FIGURE 5 is a schematic of a thermal power system in accordance with an embodiment of the present disclosure.

Disclosed herein are catalyst systems to release energy from atomic hydrogen to form lower energy states wherein the electron shell is at a closer position relative to the nucleus. The released power is harnessed for power generation and additionally new hydrogen species and compounds are desired products. These energy states are predicted by classical physical laws and require a catalyst to accept energy from the hydrogen in order to undergo the corresponding energy -releasing transition.

Classical physics gives closed-form solutions of the hydrogen atom, the hydride ion, the hydrogen molecular ion, and the hydrogen molecule and predicts corresponding species having fractional principal quantum numbers. Atomic hydrogen may undergo a catalytic reaction with certain species, including itself, that can accept energy in integer multiples of the potential energy of atomic hydrogen, m · 27.2 eV, wherein m is an integer. The predicted reaction involves a resonant, nonradiative energy transfer from otherwise stable atomic hydrogen to the catalyst capable of accepting the energy. The product is H(l/p), fractional Rydberg states of atomic hydrogen called "hydrino atoms," wherein n = 1/2, 1/3, 1/4, ... , 1/p (p≤137 is an integer) replaces the well-known parameter n = integer in the Rydberg equation for hydrogen excited states. Each hydrino state also comprises an electron, a proton, and a photon, but the field contribution from the photon increases the binding energy rather than decreasing it corresponding to energy desorption rather than absorption. Since the potential energy of atomic hydrogen is 27.2 eV, m H atoms serve as a catalyst of m · 27.2 eV for another (m + 1 )th H atom [1]. For example, a H atom can act as a catalyst for another H by accepting 27.2 eV from it via through-space energy transfer such as by magnetic or induced electric dipole-dipole coupling to form an intermediate that decays with the emission of

91.2 continuum bands with short wavelength cutoffs and energies of m ² · 13.6 eV nm In m

addition to atomic H, a molecule that accepts m · 27.2 eV from atomic H with a decrease in the magnitude of the potential energy of the molecule by the same energy may also serve as a catalyst. The potential energy of H ₂ O is 81.6 eV. Then, by the same mechanism, the nascent

H ₂ O molecule (not hydrogen bonded in solid, liquid, or gaseous state) formed by a thermodynamically favorable reduction of a metal oxide is predicted to serve as a catalyst to form H(l / 4) with an energy release of 204 eV, comprising an 81.6 eV transfer to ΗΟΗ and a release of continuum radiation with a cutoff at 10.1 nm (122.4 eV).

In the H -atom catalyst reaction involving a transition to the H ^a H state, m p = m + l

H atoms serve as a catalyst of m · 27.2 eV for another (m + 1 )th Η atom. Then, the reaction between m + l hydrogen atoms whereby m atoms resonantly and nonradiatively accept m · 27.2 eV from the (m + 1 )th hydrogen atom such that mH serves as the catalyst is given by

m - 21 ^' 2 eV + mH + H→ + m - 212 eV

a. a.

H * →H + [ m + l) - 1 ² ] · 13.6 eV - m - 212 eV

m + l m + l

mH fast + me → mH + m - 212 eV

And, the overall reaction is

a,

H→ H + [ m + l) - l ² ] - 13.6 eF

p = m + l

The catalysis reaction ( m = 3) regarding the potential energy of nascent H ₂ O [1] is

After the energy transfer to the catalyst (Eqs. (1) and (5)), an intermediate

is formed having the radius of the H atom and a central field of m + 1 times the

central field of a proton. The radius is predicted to decrease as the electron undergoes acceleration to a stable state having a radius of l/(m + 1) the radius of the uncatalyzed hydrogen atom, with the release of m ^{2 .} 13.6 eV of energy. The extreme-ultraviolet continuum radiation band due to the H intermediate (e.g. Eq. (2) and Eq. (6)) is

predicted to have a short wavelength cutoff and energy given by

and extending to longer wavelengths than the corresponding cutoff. Here the extreme- ultraviolet continuum radiation band due to the decay of the H* [aH/4] intermediate is predicted to have a short wavelength cutoff at E = m ² - 13.6 = 9· 13.6 = 122.4 eV (10.1 nm) [where p = m + 1 = 4 and m = 3 in Eq. (9)] and extending to longer wavelengths. The continuum radiation band at 10.1 nm and going to longer wavelengths for the theoretically predicted transition of H to lower-energy, so called "hydrino" state H(l/4), was observed only arising from pulsed pinch gas discharges comprising some hydrogen. Another observation predicted by Eqs. (1) and (5) is the formation of fast, excited state H atoms from recombination of fast H ⁺ . The fast atoms give rise to broadened Balmer a emission.

Greater than 50 eV Balmer a line broadening that reveals a population of extraordinarily high-kinetic-energy hydrogen atoms in certain mixed hydrogen plasmas is a well-established phenomenon wherein the cause is due to the energy released in the formation of hydrinos. Fast H was previously observed in continuum-emitting hydrogen pinch plasmas.

Additional catalyst and reactions to form hydrino are possible. Specific species (e.g. He ⁺ , Ar ⁺ , Sr ⁺ , K, Li, HC1, and NaH, OH, SH, SeH, nascent H ₂ O, nH (n=integer)) identifiable on the basis of their known electron energy levels are required to be present with atomic hydrogen to catalyze the process. The reaction involves a nonradiative energy transfer followed by q · 13.6 eV continuum emission or q · 13.6 eV transfer to H to form

extraordinarily hot, excited-state H and a hydrogen atom that is lower in energy than

unreacted atomic hydrogen that corresponds to a fractional principal quantum number. That is, in the formula for the principal energy levels of the hydrogen atom:

where a _H is the Bohr radius for the hydrogen atom (52.947 pm), e is the magnitude of the charge of the electron, and ε _o is the vacuum permittivity, fractional quantum numbers:

replace the well known parameter n = integer in the Rydberg equation for hydrogen excited states and represent lower-energy-state hydrogen atoms called "hydrinos." The n = 1 state of hydrogen and the states of hydrogen are nonradiative, but a transition between

two nonradiative states, say n = \ to « = 1 / 2 , is possible via a nonradiative energy transfer. Hydrogen is a special case of the stable states given by Eqs. (10) and (12) wherein the corresponding radius of the hydrogen or hydrino atom is given by

(13)

where p = 1,2,3,... . In order to conserve energy, energy must be transferred from the

hydrogen atom to the catalyst in units of an integer of the potential energy of the hydrogen atom in the normal n = l state, and the radius transitions . Hydrinos are formed by

reacting an ordinary hydrogen atom with a suitable catalyst having a net enthalpy of reaction of

m - 21.2 eV (14) where m is an integer. It is believed that the rate of catalysis is increased as the net enthalpy of reaction is more closely matched to m · 27.2 eV . It has been found that catalysts having a net enthalpy of reaction within +10% , preferably +5% , of m · 27.2 eV are suitable for most applications.

The catalyst reactions involve two steps of energy release: a nonradiative energy transfer to the catalyst followed by additional energy release as the radius decreases to the corresponding stable final state. Thus, the general reaction is given by

(15)

(corresponding to the 1 in the denominator) and a central field equivalent to \ m + p ) times that of a proton, and is the corresponding stable state with the radius of

that of H .

The catalyst product, H (1 / p), may also react with an electron to form a hydrino hydride ion H (1 / p), or two H (1 / p) may react to form the corresponding molecular hydrino H ₂ (l / p^j . Specifically, the catalyst product, H (1 / p) , may also react with an electron to form a novel hydride ion H (1 / p) with a binding energy E :

where p = integer > 1 , 5 = 1 / 2 , is Planck's constant bar, μ _ο is the permeability of vacuum, m is the mass of the electron, μ is the reduced electron mass given by where m is the mass of the proton, a _o is the Bohr radius, and the ionic

radius is . From Eq. (19), the calculated ionization energy of the

hydride ion is 0.75418 eV , and the experimental value is 6082.99 ± 0.15 cm ^-1 (0.75418 eV). The binding energies of hydrino hydride ions may be measured by X-ray photoelectron spectroscopy (XPS).

Upfield-shifted NMR peaks are direct evidence of the existence of lower-energy state hydrogen with a reduced radius relative to ordinary hydride ion and having an increase in diamagnetic shielding of the proton. The shift is given by the sum of the contributions of the diamagnetism of the two electrons and the photon field of magnitude p (Mills GUTCP Eq. (7.87)):

where the first term applies to H- with p = 1 and p = integer >1 for H (l I p and a is the fine structure constant. The predicted hydrino hydride peaks are extraordinarily upfield shifted relative to ordinary hydride ion. In an embodiment, the peaks are upfield of TMS. The NMR shift relative to TMS may be greater than that known for at least one of ordinary H ^" , H, H ₂ , or H ⁺ alone or comprising a compound. The shift may be greater than at least one of 0, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -1 1, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, - 22, -23, -24, -25, -26, -27, -28, -29, -30, -31, -32, -33, -34, -35, -36, -37, -38, -39, and -40 ppm. The range of the absolute shift relative to a bare proton, wherein the shift of TMS is about -31.5 relative to a bare proton, may be -(p29.9 + p ² 2.74) ppm (Eq. (20)) within a range of about at least one of ± 5 ppm, ± 10 ppm, ± 20 ppm, ± 30 ppm, ± 40 ppm, ± 50 ppm, ± 60 ppm, ± 70 ppm, ± 80 ppm, ± 90 ppm, and ± 100 ppm. The range of the absolute shift relative to a bare proton may be -(p29.9 + p ² 1.59 X 10 ^-3 ) ppm (Eq. (20)) within a range of about at least one of about 0.1% to 99%, 1% to 50%, and 1% to 10%. In another

embodiment, the presence of a hydrino species such as a hydrino atom, hydride ion, or molecule in a solid matrix such as a matrix of a hydroxide such as NaOH or KOH causes the matrix protons to shift upfield. The matrix protons such as those of NaOH or KOH may exchange. In an embodiment, the shift may cause the matrix peak to be in the range of about -0.1 ppm to -5 ppm relative to TMS. The NMR determination may comprise magic angle spinning ^l H nuclear magnetic resonance spectroscopy (MAS ¹ H NMR).

H (1 / p) may react with a proton and two H (1 / p) may react to form H ₂ (1 / p) and H ₂ (1 / p) , respectively. The hydrogen molecular ion and molecular charge and current density functions, bond distances, and energies were solved from the Laplacian in ellipsoidal coordinates with the constraint of nonradiation.

The total energy E _T of the hydrogen molecular ion having a central field of + pe at each focus of the prolate spheroid molecular orbital is

where p is an integer, c is the speed of light in vacuum, and μ is the reduced nuclear mass. The total energy of the hydrogen molecule having a central field of + pe at each focus of the prolate spheroid molecular orbital is

The bond dissociation energy, E _D , of the hydrogen molecule H ₂ (1 / p) is the difference between the total energy of the corresponding hydrogen atoms and E _T

H ₂ (1 / p) may be identified by X-ray photoelectron spectroscopy (XPS) wherein the ionization product in addition to the ionized electron may be at least one of the possibilities such as those comprising two protons and an electron, a hydrogen (H) atom, a hydrino atom, a molecular ion, hydrogen molecular ion, and H ₂ (1 / p) ⁺ wherein the energies may be shifted by the matrix.

The NMR of catalysis-product gas provides a definitive test of the theoretically predicted chemical shift of H ₂ (1 / p) . In general, the ¹ H NMR resonance οf Η ₂ (1 / p) is predicted to be upfield from that of H due to the fractional radius in elliptic coordinates

AB _T

wherein the electrons are significantly closer to the nuclei. The predicted shift,— - , for

B

H ₂ (1 / p) is given by the sum of the contributions of the diamagnetism of the two electrons and the photon field of magnitude p (Mills GUTCP Eqs. (11.415-11.416)):

where the first term applies to H ₂ with p = 1 and p = integer >1 for H ₂ (1 / p) . The experimental absolute H gas-phase resonance shift of -28.0 ppm is in excellent agreement with the predicted absolute gas-phase shift of -28.01 ppm (Eq. (28)). The predicted

molecular hydrino peaks are extraordinarily upfield shifted relative to ordinary H ₂ . In an embodiment, the peaks are upfield of TMS. The NMR shift relative to TMS may be greater than that known for at least one of ordinary H ^" , H, H ₂ , or H ⁺ alone or comprising a

compound. The shift may be greater than at least one of 0, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, -29, -30, - 31, -32, -33, -34, -35, -36, -37, -38, -39, and -40 ppm. The range of the absolute shift relative to a bare proton, wherein the shift of TMS is about -31.5 ppm relative to a bare proton, may be -(p28.01 + p ² 2.56) ppm (Eq. (28)) within a range of about at least one of ± 5 ppm, ± 10 ppm, ± 20 ppm, ± 30 ppm, ± 40 ppm, ± 50 ppm, ± 60 ppm, ± 70 ppm, ± 80 ppm, ± 90 ppm, and ± 100 ppm. The range of the absolute shift relative to a bare proton may be - (p28.01 + p ² 1.49 X 10 ^-3 ) ppm (Eq. (28)) within a range of about at least one of about 0.1% to 99%, 1% to 50%, and 1% to 10%.

The vibrational energies, E _vib , for the 1 transition of hydrogen-type

molecules H ₂ (1 / p) are

(29)

where p is an integer .

The rotational energies, E _rot , for the J to J + l transition of hydrogen-type molecules H ₂ (1 / p) are where p is an integer and / is the moment of inertia. Ro-vibrational emission of H ₂ (1 / 4) was observed on e-beam excited molecules in gases and trapped in solid matrix.

The p ² dependence of the rotational energies results from an inverse p dependence of the internuclear distance and the corresponding impact on the moment of inertia / . The predicted internucl ear distance 2c' for H ₂ (1 / p) is

At least one of the rotational and vibration energies of H ₂ (1/p) may be measured by at least one of electron-beam excitation emission spectroscopy, Raman spectroscopy, and Fourier transform infrared (FTIR) spectroscopy. H ₂ (1/p) may be trapped in a matrix for measurement such as in at least one of MOH, MX, and M ₂ CO (M = alkali; X = halide) matrix.

In an embodiment, the molecular hydrino product is observed as an inverse Raman effect (IRE) peak at about 1950 cm ^"1 . The peak is enhanced by using a conductive material comprising roughness features or particle size comparable to that of the Raman laser wavelength that supports a Surface Enhanced Raman Scattering (SERS) to show the IRE peak.

Representative energy magnitudes are 0.8 eV and 1 eV, respectively. In an embodiment, the radiation from the SF-CIHT cell comprises short wavelength radiation such as extreme ultraviolet (EUV) and ultraviolet (UV). The cell gas such as helium or the operating pressure such as about vacuum may favor the emission of short wavelength light. In an embodiment, the photocathode is responsive to ultraviolet radiation from the SF-CIHT cell. Since radiation of higher energy than the work function may be lost to kinetic energy and potentially heat, the work function of the photocathode may be matched to be close to the energy of the light such as ultraviolet radiation. For example, the photocathode work function may be greater than 1.8 eV for radiation of shorter wavelength than 690 nm, and the photocathode work function may be greater than 3.5 eV for radiation of shorter wavelength than 350 nm.

In an embodiment, the effectiveness of a photocathode is expressed as quantum efficiency defined as the ratio of the emitted electrons and the impinging photons or quanta of light. In an embodiment, the quantum efficiency is optimized by at least one of providing a strong electric field and optimizing the geometry, temperature, and material composition by means such as adding additives such as alkali metals. In an embodiment, the photocathode is selected to optimize the photon absorption parameters, electron transport properties, and surface energy states to achieve maximum photoelectron efficiency. In the latter case, the surface may be treated or activated to negative electron affinity such that conduction electrons reaching the surface have a higher energy than vacuum electrons and consequently optimally form photoelectrons. The surface of diamond, for example, can be treated or activated to negative electron affinity by cesiation, hydrogenation, coating with monolayers of LiF and RbF, and phosphorous doping using PH ₃ chemical vapor deposition. The surface of GaN photocathodes may be activated with Cs and oxygen. Other exemplary dopants comprise silicon and germanium. In a semitransparent mode embodiment, the film thickness on the back on the window is selected to optimize the quantum efficiency wherein a wavelength dependent manner, the absorption of incident photons increases with film thickness while the probability of electron transport to the surface deceases. In an exemplary semitransparent embodiment, the photocathode film thickness may be in at least one range of about 0.1 nm to 100 um, 1 nm to 10 um, 10 nm to 5 um, and 100 nm to 1 um. In general, the electrode, cathode or anode, thickness such as the electrode film thickness may be in at least one range of about 0.1 nm to 100 um, 1 nm to 10 um, 10 nm to 5 um, and 100 nm to 1 um.

In an embodiment, the photocathode comprises multiple layers to convert a wider range of photon wavelengths. The multi-layer photocathode may comprise thin layers that are transparent for photons for successive layers along the propagation path. In an exemplary embodiment, the top layer may be selective to the least penetrating light, and the successive layers are arranged to be selective based on the rate of attenuation or the penetration depth in the layered structure. In an exemplary three layer photocathode, the top layer may be selective for the least penetrating wavelengths and have the corresponding highest work function, the middle layer may be selective for the intermediate penetrating wavelengths and have the corresponding intermediate work function, and the bottom or farthest layer along the light propagation path may be selective for the most penetrating wavelengths and have the corresponding lowest work function. Other combinations of penetration depth, relative layer position, and work function are within the scope of the disclosure.

The anode comprises a material capable of collecting electrons. The anode work function may be as low as possible to increase the cell voltage according to Eq. (34). The anode work function may be lower than at least one of about 2 V, 1.5 V, 1 V, 0.9 V, 0.8 V, 0.7 V, 0.6 V, 0.5 V, 0.4 V, and 0.3 V. The anode may comprise at least one of an alkali metal such as cesium, calcium aluminate electride (C12A7:e) having a work function of about 0.76 eV, phosphorus doped diamond nanofilm having a work function of about 0.9 eV, and scandium-doped tungsten.

At least one electrode of the cathode and anode may have at least a portion of its surface structured or non-planar such that a portion of the incident light may reflect to at least one of another photocathode, a portion of the photocathode, and an optical element such as a mirror that is reflective of the light and reflects it onto another portion of the photocathode or at least one other photocathode. In this manner, the photocathodes received multiple bounces (reflections) of the incident light to increase the absorption cross section of the photocathode for producing photoelectrons. In an embodiment, the photocathode comprises a structured substrate to increase the efficiency wherein the photon absorption path in the photocathode is increased while the electron escape path remains the same or less than as for a planar substrate. An exemplary structured surface has zigzags with alternate interior angles of 45°. In another embodiment, the zigzag angles can alternate between 45° and 90°. Other angles are within the scope of the disclosure.

In an embodiment, increased photon absorption within the material while decreasing the distance the photoelectrons have to travel to the surface can be achieved by at least one of changing the angle of incoming radiation and using multiple total internal reflections within the photocathode. Using the latter method, regarding reflection of photoelectrons from the back surface of the photocathode, facilitates the attainment of greater than 50% conversion efficiency for some materials when each photon produces at most a single photoelectron. For example, some GaN photocathodes are grown on a thin buffer layer of A1N, which has large bandgap energy and serves as a reflection layer. The efficiency of the photo-conversion as a function of incoming radiation angle increases with angle relative to normal incidence until reaching the point of total reflection. Moreover, if the photocathode that is operated in a semitransparent mode can be grown on a transparent substrate such that it has a zigzag photoactive layer, the conduction electrons are produced closer to the escape surface than in the case of a flat substrate, and therefore should have higher probability to escape into vacuum. Alternatively, the photocathode is grown on a planar surface to avoid substantial degradation from lattice mismatch. For example, GaN is typically grown on a matching crystal lattice of sapphire or silicon carbide substrates with C-plane at the surface. In another embodiment, similar reflective systems and methods may be applied to the anode. In a semitransparent mode cell, the anode may comprise a double reflection type where the metal base is mirrorlike, causing light that passed through the photocathode without causing emission to be bounced back to the photocathode for a second illumination.

In an embodiment, PE or PV converter replaces the baffle 8d. The windows of the PE or PV converter may serve the functions of the baffle as a means to impede the upward trajectory of the ignition product flow and provide transparency for the light into the light to electricity converter, the PE or PV converter in this embodiment. In an embodiment, at least on of the baffle 8d and the window may be very thin such as about 1 A to 100 A thick such that it is transparent to the UV and EUV emission from the cell. Exemplary thin transparent thin films are Al, Yb, and Eu thin films.

The coilgun may comprise at least one current coil along a barrel comprising a guide for the pellet or shot, a power supply to provide a high current and a magnetic field in the at least one coil, and a switch to cause the current to flow to pull the shot or pellet towards the center of the coil wherein the current is switched off before the shot or pellet experiences a reverse force by passing the coil center. The switch may be one of the disclosure such as one comprising an IGBT. The power supply may comprise at least one capacitor. In an embodiment, current is flowed through the shot or pellet to create a shot or pellet magnetic field by the application of external power or by an external time dependent field such as a time dependent magnetic field. The shot or pellet current flow may be achieved by magnetic induction. The magnetic induction may be caused by the time-varying magnetic field of the current coils. In an embodiment, the temporal current flow to the at least one current coil is controlled to propel the shot or pellet along the barrel.

In an embodiment, the speed and location of the delivery of a shot or pellet on the roller electrode surface can be controlled to controllably repair any ignition damage to the surface. The control can be achieved by controlling the timing of the shot or pellet accelerating current pulse, as well as the current, position, and steering capability of the railgun injector, for example. The controlled-position delivery with the control of the roller speed and ignition current can facilitate the bonding of the shot or pellet to the electrode. The bonding may be by at least one of sintering, fusing, and welding of the shot or pellet to the electrode surface at the desired position. In an embodiment, a specific percentage of shot or pellets may be made to have less to none of the hydrino reactants such as at least one of hydrogen and HOH. In an embodiment, this can be achieved by forming the shot without the addition of at least one of steam and H ₂ in the pelletizer. The reduction or elimination of H ₂ O and H ₂ may be achieved by eliminating the supply or reducing the solubility in the melt by lowering the melt temperature during shot formation. Alternatively, pellets may be made absent or with diminished amounts of at least one of H ₂ and H ₂ O. The corresponding "dud" shots or pellets may be applied separately or mixed with ordinary ones at a desired percentage. In an example, one shot or pellet out of integer n is a dud that becomes bonded to the electrodes when injected. The integer n can be controlled to be larger or smaller depending on the amount of damage there is to be repaired. In an embodiment, ignition powder is recovered, forgoes the shot forming process, and is injected into the electrodes by a plasma railgun injector or augmented plasma railgun wherein some of the powder supports the plasma to cause it to be propelled. At least one of the ignition current and ignition plasma supported by ignition of other shots may cause the powder to bond to the electrodes. Excess material may be machined off by means such as by use of a precision grinder or lathe.

Alternatively, the excess material may be removed by electrical discharge machining (EDM) wherein the EDM system may comprise the electrodes and power supply.

In an embodiment of the railgun injector, the electric current runs from the positive terminal of the power supply, up the positive rail, across the armature comprising the fuel shot or pellet, and down the negative rail back to the power supply. The current flowing in the rails creates an azimuthal or circular magnetic field about each rail axis. The magnetic field lines run in a counterclockwise circle around the positive rail and in a clockwise circle around the negative rail with the net magnetic field between the rails directed vertically. In other embodiments such as an augmented railgun, current is channeled through additional pairs of parallel conductors, arranged to increase the magnetic field applied to the shot or pellet. Additionally, external magnetic fields may be applied that act on the shot or pellet when current is flowed through it. The shot or pellet projectile experiences a Lorentz force directed perpendicularly to the magnetic field and to the direction of the current flowing across the armature comprising the shot or pellet. The Lorentz force F that is parallel to the rails is given by

F = Li x B (37) where i is the current, L is the path length of the current through the shot or pellet between the rails, and B is the magnetic flux. The force may be boosted by increasing either the diam eter of the fuel shot or pellet or the am ount of current. The kinetic energy of the shot or pellet may be increased by increasing the length of the rails. The projectile, under the influence of the Lorentz force, accelerates to the end of the rails and exits to fly to the inter- electrode region. The exit may be through an aperture. With the exit, the circuit is broken, which ends the flow of current. For an exemplar}' current of 1 kA, shot diameter of 3 mm, and B flux of 0.01 T, the force is 0.03 N. The corresponding kinetic energy for 5 cm length rails is 0.0015 J. From the kinetic energy, the final velocity of an 80 mg shot is 6 m/s.

Water that is vaporized by the hot shot may be condensed into the bath by the bath chiller. The shot may be hot to provide drying. The elevated temperature of the shot may be from the residual heat from the melted state that has not fully cooled and from the resistive heating in the railgun from the current flow through the shot to cause the

Lorentz force. In an embodiment, the cell, the pelletizer such as the one comprising to chambers, the water bath, and the injection railgun may be maintained in continuity regarding the gas pressure and evacuated cell atmosphere.

Details of the ignition system 8a and its power supply 2 are shown in FIGURE 2H2. Details of the ignition system 8a and the photovoltaic converter system 26a are shown in FIGURE 213. In an embodiment, the fuel may be injected by augmented railgun injector 8f. The power supply 2 may receive power from the photovoltaic converter 26a and supply a high current to roller electrodes 8 to cause ignition of fuel to form plasma in ignition location 8e. The upward trajectory of the ignition products may be interrupted by the light transparent baffle 8d that may be concave. The ignition products may be recovered by at least one of gravity in the evacuated cell 26 and by the augmented plasma railgun recovery system comprising Helmholtz coil magnets 8c and the current flowing between electrodes 8 through the plasma. The augmented plasma railgun recovery system may comprise permanent magnets with electromagnets such as Helmholtz coils as adjustable or shimming magnets to refine the magnetic field to give fine control over the fuel recovery process. Details of the ignition 8a and the fuel formation and delivery system 8b comprising the ignition product recovery system 8c, and the pelletizer to form shot fuel 5a, and the injection system 8f are shown in FIGURE 2H4. In an embodiment, the magnets such as 8c may be located outside of the cell 26 wherein the cell material is permeable to the magnetic field of the magnets. In an embodiment, shot fuel may be injected into the roller electrodes 8 by the augmented railgun injector 8f that is fed pellets from water reservoir 11 of pelletizer 5a, conveyed by auger agitator 16a or a water jet agitator fed by agitator water jet line 15 (FIGURE 215). The roller electrodes 8 may receive high current from power supply 2 that flows through each sequentially injected shot to cause ignition of the fuel to form a brilliant light emitting plasma that is converted into electricity by photovoltaic converter 26a (FIGURES 211, 212, and 213). The upward trajectory of the ignition products may be interrupted by the light transparent baffle 8d, and the ignition products may be recovered by at least one of gravity in the evacuated cell 26 and by the augmented plasma railgun recovery system comprising

Helmholtz coil magnets 8c and the current flowing between electrodes 8 through the plasma. The ignition products may flow into a first vessel 5b of the pelletizer 5a that may comprise a crucible 5d that may be insulated with insulation 5e. The products may be heated by inductively coupled heater 5f to a melt. Shot that does not ignite may flow to the first vessel 5b of the pelletizer 5a along with the recovered ignition products. The melt may flow into the second vessel 5c of the pelletizer 5a wherein the melt may be exposed to at least one of steam and hydrogen gas supplied by inlet lines 5g and 5h. The gases may be recirculated to incorporate the gases into the melt that drips out the shot dripper 5i and quenched in the water reservoir 11 to form shot. The reservoir may have a cooling system 31a wherein the hot coolant flows into the water reservoir cooling system 3 la through inlet 3 Id, and chilled coolant exits through outlet 3 le. The temperature of the bath in connection with the evacuated cell 26 may be controlled to control the vapor pressure of water vapor in the cell. The cell pressure may also be controlled using vacuum pump 13a shown in FIGURES 211, 212, and 213.

In an embodiment shown in FIGURES 216 and 217, the pressure in the first vessel 5b and the second vessel 5c of the pelletizer 5a are the same such that the metal head pressures are equilibrated wherein the metal head pressure in the second vessel 5c may be determined by the height from the exit of the metal passage 5j to the metal level in the second vessel 5c and the metal head pressure in the first vessel 5b may be determined by the height from the exit of the metal passage 5j to the metal level in the first vessel. The metal level in the second vessel may automatically adjust due to this principle to be maintained nearly constant on average. In another embodiment, the pressure in the two vessels is different such as in the case that elevated pressure gas such as at least one of hydrogen and steam is added to the second vessel to be incorporated into the shot. In this case, a pump such as an

electromagnetic pump 5k may control the metal level in the second vessel 5c. The level may be sensed with a sensor such as a conductivity sensor or an optical one such as an infrared sensor and the level controlled by the electromagnetic pump power supply and a computer. The pelletizer may comprise at least one sensor for the flow of metal into the input of the pump 5k with a safety shut off valve to turn off the current to the pump when there is at least one of reduced volume or flow of metal into the pump. Similarly, flow sensors may be located in the vessels such as 5b and 5c that serve to provide input data such as at least one of melt flow and melt volume to a controller to shut off the heaters such as 5f and 5o when there is inadequate melt volume or flow in these sections of the pelletizer.

In an embodiment shown in FIGURES 216 and 217, each shot dripper produces shot in single file at a rate that matches the injection rate and the ignition rate to achieve a steady state power output and continuity of mass flow. This matching rate and single file aspect of the shot stream from the dripper may be used to load the injector such as the railgun injector at the matching rate. Each shot discharged from the dripper is initially in a molten state. The shot may be cooled in route to the input to the injector. The shot may be flowed single file along a water slide 51. The water slide 51 may comprise a conduit such as a channel, chute, or trough having streaming water such as that provided by water jet 16 or a water bath 11 that cools the shot as it flows from the dripper to the input to the injector such as the railgun. The channel may direct shot directly to the railgun injector without discharging them into the water bath 11. The water may flow around the rails in a manner to load the shot onto the rails to be injected. Alternatively, the channel may discharge the shot into a water bath 11 that may be shallow enough to maintain a single file shot stream that flows to the injector input. The water may be recirculated through a chiller 3 la to maintain a low temperature and remove the heat released in the partial cooling of the shot. The shots may arrive in single file to the railgun injector 8f such that at least one of the slide and shallow bath may replace the agitator such as the auger 16 or water jet 16a (FIGURE 215) to facilitate loading the railgun injector 8f.

When the shot cooling is ceased with the shot having an elevated temperature, less cooling load will result from the water-stream slide versus the full water reservoir system of cooling the shot to a much lower temperature. In an embodiment, the shot may be cooled just sufficiently to form a thin solid shell on the outer surface such as a shell having a thickness in at least one range of about 1 nm to 100 um, 10 nm to 10 um, and 100 nm to 1 um. In an embodiment, the hot shots will require at least one of less energy, lower ignition current, and less time under ignition power to ignite by arriving preheated; thus, some of the heat from the pelletizer is recovered. Moreover, the ignition may be more complete such that the fuel formation and power release is more efficient with higher gain. The only partial cooling with the injection of preheated shot may serve as the heat recuperator. The preheated temperature may be in at least one range of about 100 °C to 950 °C, 300 °C to 900 °C, and 400 °C to 900 °C. The ignition energy per shot may be essentially that to melt the thin shell. The ignition product may comprise at least one of plasma, molten metal, and elevated temperature molten metal. The products may be recovered to the input to the pelletizer while still at an elevated temperature such as at least one temperature range of about 100 °C to 950 °C, 300 °C to 850 °C, and 400 °C to 900 °C. The hot powder may be further elevated in temperature by the heater such as the inductively coupled heater. The elevated temperature may be in at least one range of about 965 °C to 3000 °C, 965 °C to 2000 °C, and 965 °C to 1500 °C. With preheated power, the pelletizer input heat energy may be a small fraction of that to melt room temperature ignition product. In an optimized flow of reactants, the round trip energy consumption comprising the contributions from melting the preheated thin-shelled shot and melting the hot recovered products to an elevated melt temperature may be minimized.

Consider an exemplary embodiment of a 77 mg Ag shot corresponding to a sphere of 2.5 mm diameter having a density of 90% of the of pure Ag due to incorporated H ₂ and H ₂ O wherein the powder temperature at the inlet to the first vessel of the pelletizer is about 900 °C, the Ag melt is heated to 1300 °C, the shot shell thickness is about 1 um, the temperature of the shot injected into the roller electrodes is about 800 °C, and the shot may ignite when the shot melts. Then, considering just the metal as the dominant contributor, the round-trip input energy for the reactants is about 20 J compared to about 400 J of output light. In an embodiment shown in FIGURES 218 and 219, the injector comprises a pump such as an electromagnetic pump 5k that pumps molten fuel such as molten silver metal treated with a source of hydrogen and a source of catalyst such as H ₂ and steam into the gap between the electrodes such as roller electrodes 8. The pump 5k may operate by the same principle as that of the railgun wherein a current is passed through the melt and a

perpendicularly applied magnetic field creates a Lorentz force in the desired direction of flow. Other electromagnetic pumps known in the art capable of pumping the molten fuel such as those using special coils that work on the principle of induction are within the scope of the disclosure. The pump may also comprise a mechanical pump. In an embodiment, mechanical molten metal pumps incorporate graphite or ceramic impellers.

The pump 5k may comprise and electromagnetic pump that comprise powerful, permanent magnets and DC current to propel the molten metal, eliminating a mechanical pump impeller. A motive force is directly applied to the liquid metal by supplying an electrical current through the metal within a strong magnetic field according to the Lorentz Force Law. In an embodiment the strength of the current directly controls the force on the metal, and hence the volume of flow. In an embodiment, the magnetic field is supplied by high-strength, permanent magnets, and the current is direct, or DC current, supplied by industry standard rectifier power supplies. In an embodiment, the result is an electromagnetic pump with higher flow rates at reduced energy consumption compared to AC

To operate at high temperature such as that of the mel ting point of silver such as in the range of 962 °C to 1300 °C, the tube of the electromagnetic pump may comprise a high-temperature metal such as a refractory metal such as molybdenum, tantalum, niobium, or tungsten pump tube. In the case that the pump tube is difficult to machine, it may be fabricated by other methods known in the art such as casting, electrical discharge machining, and metal printing.

In an embodiment, the pump tube has at least one property of wettability by silver such that it is protected from reaction with H ₂ O and is non-reactive with water. Suitable exemplary materials for the tube that lack H ₂ O reactivity with sufficient melting points are at least one of the metals and alloys from the group of Cu, Ni, CuNi, Haynes 188, Haynes 230, Haynes HR-160, Hastelloy C, Hastelloy X, Inconel, Incoloy, carbon steel, stainless steel, chromium-molybdenum

(chromoly) steel such as modified 9Cr-lMo-V (P91), 21/4Cr-lMo steel (P22), Co, Ir, Fe, Mo, Os, Pd, Pt, Re, Rh, Ru, Tc, Ta, Nb, and W. Any oxide coat on the inner wall of the pump tube that may decrease the current through the pump tube walls and the connection with the melt such as silver melt inside of the tube may be removed by methods known by those skilled in the art such as at least one of chemical, mechanical, and plasma etching and electroplating. The chemical method of removing the inner wall oxide may comprise etching with acid and neutralization. The plasma method of removing the inner wall oxide may comprise at least one of electrical discharge machining and vapor deposition. In an embodiment, any oxide coat is removed for the inside of the pump tube by means known in the art such as acid or plasma etching. The inside of the tube may be coated with the metal of the fuel melt such as silver or silver-copper alloy to protect the inside wall from oxidation until put into use. The coating may be achieved by at least one method comprising application of the molten metal, electroplating, electroless plating, vapor deposition, chemical deposition, and other methods known by those skilled in the art.

The pump further comprises bus bas or metal tabs having electrical connections to the side of the tube in this same area that introduce an electrical current flow into the molten metal. The bus bars may be attached with high resistance welds, or ceramic feed-throughs 5k31 (FIGURES 2124 and 2127) may be used for the bus bars of the EM pump tube that supply current to the pumped molten metal such as the Ag metal. Ceramic feed-throughs may be cooled by means such as gas or water cooling. Each EM pump bus bar or tab may be contacted directly to the molten metal such as molten silver by the steps of (i) machining penetrations such as rectangular penetrations in the sides of the tube wall on opposite walls that are each a tight fit with the bus bar when the tube is at an elevated temperature, (ii) heating the tube to expand the penetrations to accommodate the bus bars, (iii) inserting the bus bars through the penetrations, (iv) cooling the tube to compression bond the bus bars to the pump tube, and (v) operating the pump at a lower temperature than that used to expand the penetrations to accommodate the insertion of the bus bars. Alternatively, each EM pump bus bar or tab may be contacted directly to the molten metal such as molten silver by the steps of (i) machining flaps in the sides of the tube wall on opposite walls that are each a tight fit with the bus bar, (ii) inserting the bus bars through the slits of the flaps, and (iii) mechanically squeezing the flaps onto the bus bars to form a compression bond of the bus bars to the pump tube. In another embodiment, the tabs may be welded to inwardly projecting dimples made in the opposite side walls of the flattened tube. In another embodiment, the current may be selectively supplied to the melt inside of the tube by increasing the contact area of the pump bus bar with the metal relative to the area in contact with the pump tube wall. The contact area with the melt may be increased by inserting the bus bar into the melt by having it protrude through the pump tube wall inside of the tube. The inner protrusion may comprise a shape or structure such as a curved plate to increase the surface area of contact with the melt. The bus bar may be fastened to the pump tube wall by at least one of welds and compression bonding. Exemplary pump tubes and bus bars comprise at least one from the group of zirconium, niobium, titanium, and tantalum.

The bus bars may each comprise a coating of low conductively such as an oxide coat at the region of contact of the bus bar with the tube wall at the penetration. Exemplary bus bars and the corresponding low conductivity coatings are zirconium and zirconium oxide, niobium and niobium oxide, titanium and titanium oxide, nickel and nickel oxide, and tantalum and tantalum oxide, respectively. The oxide may be formed by heating in oxygen or by anodizing. The sections that are desired to be conductive that contact the melt may be masked during oxidation, or the oxide may be removed from the melt contact regions after the bus bar is coated with oxide by means such as mechanical abrasion, chemical etching, or chemical reduction. The high resistance between the bus bar and the cell wall causes the low resistance electrical path to be through the metal melt inside the pump tube. The electrical current may flow across the flattened section while the magnetic flux may pass through the flattened section at right angles to the current flow, and this may produce a force on the metal that is at right angles to the current and magnetic flux. The electromagnetic pumps may operate on direct current or alternating current. In the former case, the magnets may comprise permanent magnets or DC electromagnets. When operated with alternating current, the magnets comprise AC electromagnets. In the AC case, the direction of the flow of electricity in the metal may change every half-cycle, and the electromagnets may also be powered by the same alternating current such that the magnetic field may also change direction every half-cycle, so the force on the metal may pulsate but may always be in the same direction. The pump may be convection cooled. Although, if the pumped metal temperature such as silver is high such as 1000 °C and higher, the pump may be cooled with supplemental cooling such as forced convection and water-cooling. In an embodiment, energy is dissipated as ohmic heating of the metal by the flow of current through the metal to cause pumping by electromagnetic pump 5k, and this energy supplements the heating by the heater 5o of the second vessel 5c. In an embodiment, the metal may be directly resistively heated by flowing current through it using electrodes in contact with the metal.

The pump 5k may comprise a 3-phase linear annular induction pump. The pump may comprise two annular tubes separated by a space. The metal may flow through the annular space between two concentric tubes wherein the inner of the two tubes may contain a magnetic core, through which the lines of a moving radial magnetic field are looped. A 3- phase stator around the tube may develop the field. The flow of induced currents may be circular, within the annular space, cutting the lines of the field. An axially exerted force may result that may move the liquid metal through the pump. The pelletizer may comprise a flow meter such as one known by those skilled in the art. The flow meter may comprise a Lorentz force velocimeter or Lorentz flow meter that measures the integrated or bulk Lorentz force resulting from the interaction between the liquid metal in motion and an applied magnetic field. The flow meter may comprise one based on Faraday's law of induction wherein a magnetic field is applied along the transverse x-axis, a set electrodes are applied along the transverse y-axis, and the flow of the conducting molten metal along the z-axis produces a voltage across the electrodes that is linearly proportional to the velocity of the flow according to Faraday's law of electromagnetic induction. The flow meter may comprise a contactless electromagnetic flow meter that operates by measuring the amount of distortion in a magnetic field that is caused by movement of a conductor within that magnetic field. To achieve this, permanent magnets may be set near the moving material. The moving material may or may not be contained within a pipe or conduit. The amount of shift of the magnetic field may be measured in the direction of melt flow corresponding to the velocity of the melt that is read out by a calibrated indicator as a flow rate.

The pressure of the molten fuel may be sufficient to form shot 5t as it ejects out of a nozzle 5q. The gas pressure may be elevated relative to the cell pressure such as in at least one range of about 0.01 Torr to 100 atm, 1 Torr to 10 atm, 10 Torr to 5 atm, and 100 Torr to 1 atm. The electromagnetic pump 5k may develop a pressure greater than that of the gas pressure to cause melt flow and ejection from the vessel and nozzle. The shot 5t may comprise projectiles that enter the inter-electrode region to cause contract between the otherwise non-contacting electrodes 8. The consequential high current flow results in ignition of the fuel such as the formation of plasma. In an embodiment, the fuel may comprise a continuous stream rather than shot or a combination of intervals of continuous stream mixed with shots. In an embodiment, the pressure in the pelletizer 5a developed by the pump 5k is greater than at least one of the pressure of any gases applied to the melt such as H ₂ and steam and the pressure corresponding to gravity at a height of the electrodes over the nozzle 5q. In the latter case, after leaving the nozzle 5q, the ejected fuel has sufficient kinetic energy to transport it to the ignition site between the electrodes against gravity.

In an embodiment, the ignition products are recovered and collected in the first vessel of the pelletizer 5b and are melted. The melt may be pumped by at least one electromagnetic pump 5k. In an embodiment, the inlet of the first vessel 5b may be aligned along the vertical axis (z-axis) of the cell 26. The melt may flow from the first vessel 5b into the pump 5k that pumps the melt into the second vessel 5c. The second vessel 5c may have a section that bends such that the melt flow direction gradually changes from along the negative z-axis to along the positive z-axis towards the injection or ignition site comprising the region of closest proximity of the opposing separated electrodes 8. At least one of the first vessel 5b and the second vessel 5c may be pipe-like. The vessels comprise an arc, semicircle, U-shape, or other such shape to permit the receipt of ignition product from the cell at the inlet and ejection of regenerated fuel into the electrodes of the cell at the outlet or nozzle. In an embodiment for improved packaging of the electromagnetic (EM) pump in the pelletizer, the EM pump height from the pump tube to the top of the EM pump is reduced. The height of the permanent magnet such as a neodymium magnet and a shallow magnetic pole piece of the magnetic circuit may give the desired overall height. This EM pump section distal to the pump tube may be cooled. The distal section may comprise a thermally insulating spacer and a cold plate in the magnetic circuit to thermally isolate and cool the distal magnet. The cool or cold plate may comprise a micro-channel plate such as one of a concentrator photovoltaic cell such as one made by Masimo or a diode laser cold plate that are known in the art.

The second vessel 5c may comprise at least one manifold that supplies at least one of H ₂ and gaseous H ₂ O to the melt such as hydrogen manifold and input lines 5w and steam manifold and input lines 5x as the melt flows towards a nozzle 5q at the end of the pipe-like second vessel 5c directed at the injection site. In an embodiment, the H ₂ and H ₂ O injection system comprises gas lines, manifolds, pressure gauges, regulators, flow meters, and injectors and may further comprise a H ₂ -steam mixer and regulator in case that both gas are injected with a common manifold. In an embodiment, liquid water may be injected into the melt. The injection may be achieved by at least one of a pump such as a peristaltic pump and gravity feed. In an embodiment, the metal of the fuel may comprise a copper-silver alloy. H ₂ gas injected into the melt through hydrogen manifold and input lines 5w may be used to reduce any oxide of the alloy such as CuO formed during the operation of the cell.

Additionally, oxide of the alloy may be reduced in situ in the cell by addition of hydrogen gas that may be intermittent. Oxide of the alloy may also be reduced by hydrogen treatment outside of the cell.

The pelletizer 5a may be heated with at least one heater such as at least one inductively coupled heater. In an embodiment, the inductively couple heater may comprise and inductively coupled heater power supply 5m. The pelletizer 5a may be heated with a first inductively coupled heater coil 5f that may extend along the first vessel 5b from its inlet to the inlet of the electromagnetic pump 5k. The first inductively couple heater comprising coil 5f may be circumferential to the first vessel 5b having crucible 5d and insulation 5e. The heater may further comprise a second inductively coupled heater coil 5o that may extend along the second vessel 5c from the outlet of the electromagnetic pump 5k to the nozzle 5q of the second vessel 5c. The second inductively couple heater comprising coil 5o may be circumferential to the second vessel 5c having crucible 5d and insulation 5e. The

corresponding first and second heating coils define a first and second heating section or zone. The first section may be heated to a temperature that is at least above the melting point of silver (962 °C) to form the melt that is pumped. The vessel and coil may comprise a high Q cavity further comprising the recovered product melt. In an embodiment, a gas such as at least one of H ₂ O and H ₂ may be injected to increase the resistivity of the melt to improve the coupling of the radiation from the inductively coupled heater with the melt. The second section may be superheated relative to the first. The temperature of the melt in the second section may be maintained in at least one range of about 965 °C to 3000 °C, 965 °C to 2000 °C, and 965 °C to 1300 °C. An optical pyrometer, thermistor, or thermocouple may be used to monitor the temperature of the melt. In an embodiment, power dissipated in the pump 5k due to mechanisms such as resistive heating may contribute to heating the melt. The superheating may increase the absorption of at least one treatment gas such as at least one of H ₂ and steam in the melt.

In an embodiment, the pelletizer may comprise a plurality of heaters such as inductively coupled heaters each comprising an antenna such as a coil antenna and an inductively coupled heater power supply 5m to supply electromagnetic power to heater coils 5f and 5o through inductively coupled heater leads 5p. The inductively coupled heater power supply 5m may comprise a shared power supply to the plurality of antennas wherein the power to each antenna may be adjusted by a circuit such as a matching or tuning circuit. In another embodiment, each antenna may be driven by its independent power supply. In the case, of shared or separate power supplies, each heater may further comprise a controller of the power delivered by each coil. In another embodiment, the inductively coupled heater comprises one antenna driven by one power supply wherein the antenna is designed to selectively deliver a desired proportion of the power to each of the first heating section and second heating section. The heating power may be divided between the two sections according partition means such as fixed differences in (i) antenna gain achieved by different numbers coil turns for example, (ii) variable, controllable antenna gain, (iii) switches, and (iv) matching or tuning networks. The two coil sections may be connected by additional inductively coupled heater leads 5p between the sections that may bridge the electromagnetic pump 5k. The leads may be designed to transmit rather than dissipate power such that the heating power is selectively delivered and dissipated into the fuel melt by the coils 5f and 5o.

The sections heated by inductively coupled heaters may each comprise a crucible comprising material transparent to the radiation such as RF radiation of the inductively coupled heater. Exemplary materials are silicon dioxide such as quartz or silica, zirconia, and sapphire, alumina, MgF ₂ , silicon nitride, and graphite. Each crucible may be insulated with high temperature insulation 5e that is also transparent to the radiation of the inductively coupled heater. The portion of the second vessel 5c that is in contact with the

electromagnetic pump 5k may comprise a conductor and a magnetic-field-permeable material such that the applied current and magnetic field of the pump 5k may pass through the melt. The RF transparent sections may be connected to the conductive and magnetic-field- permeable section by joints such as ones comprising a flange and a gasket. The joint may comprise a clamp such as a C-clamp, clamshell type, bolted fittings, or tightened wires. The joints may operate at high temperature and may be stable to molten fuel. An exemplary gasket is a graphite gasket. Alternatively, the gaskets may comprise a wet seal type common in molten fuel cells wherein the fuel is liquid in the vessel and is solid at the perimeter of the joints or unions of the vessel with the pump wherein the temperature is below the melting point. The union may comprise at least one of the penetration for the pipe bubbler and the valve.

In the case that the pump is of a type suitable for a common crucible and tube material and the pump tube, the pump tube through the electromagnetic pump 5k may comprise a material that is transparent to the radiation of the inductively coupled heater. The material of the pump tube may be the same material as that of at least one of the first vessel and the second vessel. The joint may comprise a ceramic-to-ceramic joint wherein ceramic comprises a material that is transparent to the radiation of the inductively coupled heater such as at least one of silica, quartz, alumina, sapphire, zirconia, MgF ₂ , and silicon nitride.

Alternatively, in the case that the pump is of a type suitable for a common crucible and tube material and the pump tube comprises the common or the same material as at least one of the vessels, the joint may be eliminated such that there is continuity of the vessel through the pump. An exemplary material of at least one of the vessels and the pump tube of an exemplary induction-type or mechanical pump is silicon nitride. In another embodiment, at least one component from the group of the first vessel, the second vessel, the manifold section of the second vessel, and the pump tube may be comprise a material that absorbs the radiation of the inductively coupled heater such as a metal or graphite such that the fuel metal contained in the component is heated indirectly. The heater may heat the component, and heat transfer from the heated component may secondarily heat the fuel metal inside of the component.

In a specific exemplary embodiment, the first vessel 5b comprises an RF transparent material such as quartz. The quartz section of the first vessel is connected to a metal elbow such as a high-temperature stainless steel (SS) elbow that connects to a metal pipe tube such as a high-temperature stainless steel (SS) pipe tube of the electromagnetic pump 5k. The tube connects to the second vessel 5c that comprises a metal elbow such as a high- temperature stainless steel (SS) elbow that further connects to an RF transparent material such as quartz. The quartz tube ends in the nozzle 5q. The second vessel may further comprise an S or C-shaped section that may penetrate the cell and align the nozzle 5q with the gap 8g of the electrodes 8. The each joint between sections that connect may comprise a clamp and a gasket such as a graphite gasket. In an embodiment, the pelletizer comprises a short heating section 5b such as an RF transparent section, a metal joint transition to the pump tube, the electromagnetic pump 5k that may be in a vertical section of the vessel 5b, a transition to an elbow such as a metal elbow having a metal fitting or penetration for a pipe bubbler 5z that runs through a second longer RF transparent heating section 5c that ends in the nozzle 5q. The RF transparent sections comprising the first and second vessels may comprise quartz, the quartz to metal joints may comprise quartz and metal lips on the joined sections held together with clamps. An exemplary pipe tube size and vessel size are 1 cm ID and 2 cm ID, respectively. The pipe tube may comprise a high temperature stainless steel, and the RF transparent vessel may comprise quartz.

In another embodiment, at least one of the pelletizer components such as the melt conduit components and gas delivery component comprising at least one of the first vessel 5b, second vessel 5c, pump tube, manifold section of the second vessel 5c (FIGURE 2111), and pipe bubbler 5z (FIGURE 2113) may comprise a material that absorbs at least some power from the inductively coupled heater(s) and indirectly heats the fuel melt such as silver or Ag-Cu alloy melt. In the latter case, the vessel walls such as quartz, silica, sapphire, zirconia, alumina, or ceramic walls may be transparent to the RF power of the inductively coupled heater. The pelletizer components may comprise high temperature stainless steel, niobium, nickel, chromium-molybdenum steel such as modified 9 Cr-lMo-V (P91), 21/4Cr- lMo steel (P22), molybdenum, tungsten, H242, TZM, titanium, chromium, cobalt, tungsten carbide, and other metals and alloys that have a melting point higher than that of the fuel melt. The metal may have a high efficiency for absorbing the radiation from the heater. The components such as the vessels may be narrow to effectively heat the fuel melt indirectly. Exemplary vessels are tubes having tube sizes of the 1/4 inch to 3/8 inch ID. The melt contact surfaces of the components such as the vessels, pump tube, and pipe bubbler may be pre-oxidized by means such as heating in an oxygen atmosphere in order to form a passivation layer to prevent reaction with injected steam or water that becomes steam. In an embodiment, the walls of the component may be wetted with the melt such as silver melt that protects the walls form reaction with water. In this case, water reactive metals may be used for the pelletizer component. The joints may be welds, Swagelok, and others known in the art for connecting metal parts. The parts may be made of the same materials as the pump tube such as at least one of zirconium, niobium, titanium, tantalum, other refractory metal, and high temperature stainless steel such as at least one of Haynes 188, Haynes 230 and Haynes HR-160.

In an embodiment, at least one vessel of the pelletizer that is heated by at least one of the inductively coupled heaters such as 5f and 5o comprises a material such as a metal that absorbs the radiated power of the inductively coupled heater and indirectly heats the metal such as silver that is contained in the vessel. Exemplary metals that are very efficiency at absorbing the RF radiation of the inductively coupled heater are tantalum, niobium, ferrous metals, and chromoly metal. In an embodiment, at least one vessel of the pelletizer comprises tubing comprising a material that efficiently absorbs the radiation from the inductively coupled heater such as tantalum, niobium, or a ferrous metal such as chromoly. The tubing may be coiled to be permissive of heating a longer length section within a coil of an inductively coupled heater. The tubing may have a small diameter such as in the range of about 1 mm to 10 mm to effectively indirectly heat the metal inside of the tubing. The tubing such as polished or electro-polished tubing may have a low emissivity. The tubing may be wrapped with insulation such as insulation substantially transparent to the radiation of the inductively coupled heater. The insulation may be effective at minimizing the conductive and convective heat losses and may further at least partially reflect infrared radiation from the tubing to decrease radiative power losses. In an embodiment, the pelletizer may further comprise a vacuum chamber or a cell extension that provides a vacuum chamber around at least of portion of the pelletizer. The vacuum about the vessels may decrease conductive and convective heat losses and lower the required heater power to maintain the melt at the desired temperatures. The vacuum may further decrease oxidation of the tubing that maintains its desired low emissivity.

In the gas treatment section comprising gas manifolds, the vessel wall may be comprised of a material that has a diminished to low permeability to hydrogen and is capable of a high temperature. Suitable materials are refractory metals such as tungsten and molybdenum and nitride bonded silicon nitride tube. The vessel may be lined with insulation in the absence of the inductively couple heater in the manifold section. This section may be insulated and heated by the contiguous section of the second vessel from which the melt flows into this section. If necessary, in addition to insulation, the temperature may be maintained by an inductively coupled heater that heats the metal wall and indirectly heats the melt. Alternatively, another type of heater such as a resistive heater may be used. In an embodiment, the manifold section further comprises a mixer to increase the rate of incorporation H ₂ and gaseous H ₂ O into the melt. The mixer may comprise an

electromagnetic type such as one that utilizes at least one of current and magnetic fields to produce eddy currents in the melt or mechanical type that comprises a moving stirrer blade or impeller. The H ₂ and gaseous H ₂ O become incorporated into the melt to form molten fuel that is ejected from a nozzle 5q at the ignition site. The pelletizer 5a further comprises a source of H ₂ and H ₂ O such as gas tanks and lines 5u and 5v that connect to the manifolds 5w and 5x, respectively. Alternatively, H ₂ O is provided as steam by H ₂ O tank, steam generator, and steam line 5v. The hydrogen gas may be provided by the electrolysis of water using electricity generated by the generator.

The ejection of elevated pressure melt from the nozzle 5q achieves injection of fuel into the electrodes wherein the elevated pressure is produced by the at least one

electromagnetic pump 5k. The pressure may be increased by controlling the cross sectional area of the ejection nozzle 5q relative to that of the melt vessel 5c. The nozzle orifice may be adjustable and controllable. Sensors such as conductivity or optical sensors such as infrared sensors and a computer may control the pressure of pump 5k and the injection rate. The nozzle 5q may further comprise a valve such as one of the disclosure that may provide additional injection control. The valve may comprise a needle type with the nozzle opening as the valve seat. In an embodiment of the SF-CIHT cell comprising an electromagnetic pump 5k, a fast controller such as a fast current controller of the electromagnetic pump serves as a valve since the pressure produced by the pump is eliminated at essentially the same time scale as the current according to the Lorentz force (Eq. (37)) that depends on the current. The shot size may be controlled by controlling at least one of the nozzle size, the pressure across the nozzle orifice, vibration applied to the nozzle with a vibrator such as an electromagnetic or piezoelectric vibrator, and the temperature, viscosity and surface tension of the melt. The movement of the shots may be sensed with a sensor such as an optical sensor such as an infrared sensor. The position data may be feedback into at least one of the controller of the injection and the ignition to synchronize the flow of fuel into the ignition process. The nozzle 5q may be surrounded by a Faraday cage to prevent the RF field from inducing eddy currents in the shot and causing the shot to deviate from a straight course into the electrode gap where ignition occurs.

The shot formed by surface tension following ejection from the nozzle 5q may radiate heat and cool. The flight distance from the nozzle 5q to the point of ignition between the electrodes 8 may be sufficient such that the metal forms spheres, and each sphere may cool sufficiently for a shell to form on the outside. To enhance the cooling rate to assist in the formation of at least one of spherical shot and spherical shot with an outer solid shell, the ejected molten fuel stream may be sprayed with water such as water droplets with a sprayer such as one of the disclosure. An exemplary water sprayer is Fog Buster Model #10110, U.S. Patent No. 5,390,854. Excess water may be condensed with a chiller to maintain a rough vacuum in the cell. In an embodiment, the sprayer and water condenser or chiller may be replaced with a nozzle cooler 5s that may cool the shot 5t just as it is ejected. The cooling may comprise at least one of a heat sink such as one comprising a thermal mass that radiates heat, a heat exchanger on the nozzle with lines 3 Id and 3 le to a chiller, and a chiller 31a, and a Peltier chiller on the nozzle 5s. The melt flowing into the nozzle section of the pelletizer 5a may have a substantially elevated temperature in order to absorb applied gases such as H ₂ and H ₂ O in the upstream gas application section. The melt temperature may be quenched with the nozzle cooling. The temperature may be lowered to just above the melting point just as the melt is ejected. The lower-temperature melt may form spheres, and each may

subsequently form a solid shell with radiative cooling as it travels from the nozzle to the electrodes. Using a rough, high capacity cooling means such the heat sinking and the heat exchanger and chiller, the temperature at ejection may be established to within a rough temperature range such as to within about 50 °C of the melting point of the melt. A more precise temperature near the desired temperature such as to within about 1 to 5 °C of the melting point of the melt may be achieved with a highly controllable, low capacity cooler such as the Peltier chiller. The pelletizer 5a may further comprise a chiller to cool the inductively coupled heater which may comprise a separate chiller or the same chiller as at least one of the nozzle chiller 31a and power converter chiller such as the PV converter chiller 31. The ignition system 8a (FIGURE 2H2) may also be cooled with a heat exchanger that rejects the heat to a chiller that may comprise one such as 31 that also cools another system such as the PV converter. The ignition system cooler may cool at least one of the electrical connecting bearing such as the plain bearing or slip ring, the roller shafts, and the roller electrodes. The ignition system cooler may comprise a heat exchanger such as a water jacket about the slip ring. The water jacket water may also flow through the shafts 7 and roller electrodes 8. The water flow may be connected with the shafts 7 through water tight, shaft sealing bearings or watertight slip rings at the ends of the shafts that are well known in the art.

The ignition of the fuel forms hydrinos and oxygen that may be pumped off with a vacuum pump 13a (FIGURE 212) such as a root pump, a scroll pump, a cryopump, a diaphragm pump, a dry vacuum root pump, and others known to those skilled in the art. Excess water and hydrogen may be recovered and recirculated. The water may be removed by differential pumping. In an embodiment, hydrogen and oxygen formed in the plasma may be removed by pumping and other means of the disclosure such as by the separatory means. The removal of the hydrogen and oxygen may be used as a means to remove excess water. In the case that an atmosphere comprising water is maintained at the electrodes, excess water may be removed by pumping. The water may be condensed at a chiller in the cell 26 or connected with the inside of the cell 26 and reused. Hydrogen may be recovered with a scrubber such as a hydrogen storage material. Alternatively, it may be pumped off as well using pump 13a, for example. The pressure may be maintained in a pressure range that prevents at least one of excessive attenuation of the light emitted by the cell and allows the ignition particles to fall substantially unimpeded under the influence of gravity. The pressure may be maintained in at least one pressure range of about 1 nanoTorr to 100 atm, 0.1 milliTorr to 1 atm and 10 milliTorr to 2 Torr.

The ignition of hot fuel may require less energy than that of cold fuel; so, the timing of the ignition may be earlier in the hot-fuel case. The timing of the ignition may be controlled to achieve the formation of light in a desired region such as one that provided light directed towards the power converter such as the photovoltaic converter 26a (FIGURE 212). In the case that fuel is injected from below the roller electrodes 8, the roller speed may be increased to transport the fuel upward to cause the light to be emitted in the desired region. The system may comprise an ignition current delay element such as a delay line to delay the ignition as the fuel is transported by the rollers such that the light is produced in the desired region. The power may be controlled by controlling the injection rate and size of the shot. The flow rate may be controlled by controlling the pumping rate. The H ₂ and H ₂ O content may also be controlled by controlling the gas absorption conditions such as gas pressures, exposure time, and melt temperature to control the power output of the SF-CIHT cell.

In an embodiment to in situ repair the electrodes such as roller electrodes 8, the melt such as molten silver may be injected absent at least one of gas treatment and cooling such as with the water spray, the heat exchanger and chiller, or the Peltier chiller. The untreated metal serves as "dud" material in that the ignition to form hydrinos is absent such that the material may bond to the electrode surface. The bonding may be more dispersed and uniform in the case that the melt is not cooled into shot having an external shell. Molten droplets may impact the electrode surface with injection to cover the surface over time with new metal. The excess metal may be machined by means of the disclosure such as by use of at least one of a dressing wheel, precision grinder, and lathe. The milling may be achieved with a fixed abrasive blade that mills the surface as the roller electrode rotates. The height of the blade may be adjustable. Alternatively, the excess material may be removed by electrical discharge machining (EDM) wherein the EDM system may comprise the electrodes and power supply. Each electrode may have a dressing wheel to condition the surface. The rollers may be smoothed and formed to a desired radius by at least one of milling, grinding, lapping, super finishing and heat-treating. In another embodiment, the electrode mending or repair system comprises a sensor such as an optical sensor such as a laser to detect roller damage. A controller may control the deposition, removal of excess material, and dressing to repair blast damage to maintain the electrodes within certain desired size tolerances.

In an embodiment that may be independent of the cell's orientation with respect to gravity, the ignition products may be recovered by at least one of an electrostatic and an electromagnetic recovery system. In an embodiment, the electrostatic recovery system comprises at least one set of electrodes that may be maintained at high voltage that causes the ignition product powder to become charged by one electrode such as the positive (negative) electrode and the charged particles are collected by the oppositely charged electrode such as the Negative (positive) electrode. The particles may be charged by electrons produced by a discharge at the negative electrode such as a coronal discharge. Alternatively, particles such as ones comprising silver may become positively charged in a high field between the ESP electrodes. The direction of the electric fields created by the electrodes may be such that the particles travel in a trajectory that is along at least two directions of a Cartesian coordinate system. The particles may travel directly to a collector that may be the input of the pelletizer. The powder may be melted in the pelletizer, and an electromagnetic pump may pump the melt to transport it. The melt may be treated with gases to become fuel and injected into the electrodes.

In another embodiment, the ignition product powder may be transported

predominantly along one axis of the Cartesian coordinate system to be collected on at least one collection electrode. The powder may then be transported to the pelletizer by at least one transporter such as a mechanical and electrostatic transporter. The electrodes may comprise barrier electrodes wherein a charge is maintained on the surface of the collection electrodes. The collected charged powder may be maintained in a charged state. The power may be transported by a series of electrically isolated collection electrodes wherein electrode n + 1 of the series of integer n electrodes is electrically charged by the application of a voltage while electrode n is discharged or oppositely charged such that the powder is attracted to electrode n + 1 and no longer attached or is repelled by electrode n. The series of electrodes may be sequentially activated and deactivated electrically to move the powered to a desired location such as to the pelletizer. The n series of electrodes may move the powder in any desired direction such as vertically in the case that the standard design with the light directed vertically is operated in an upside-down orientation. In an embodiment, the series of electrodes may move the powder to a plasma-containing region of the cell wherein the augmented plasma railgun recovery system of the disclosure may complete the recovery of the powder. In the case that the plasma conductivity is low, an electrostatic precipitator may be used to collect the ignition products or direct them to a region that has a high conductivity. In a region of high plasma conductivity, the ignition product may be recovered by at least one of a barrier electrode electrostatic precipitator and an augmented plasma railgun recovery system.

The electrostatic precipitator (ESP) may comprise a high voltage power supply that may be run off of at least one of the photovoltaic (PV) converter and the power conditioner of the PV converter power. The power supply may supply power between the ESP electrodes to cause the electrostatic precipitation. In an embodiment, the ESP precipitator further comprises a set of electrodes such as a central electrode such as a wire electrode 88 (FIGURE 2123) of a polarity and at least one counter electrode 89 of opposite polarity. The wire electrode may create a coronal discharge with the counter electrode(s). The wire may comprise objects such as sharp needles to intensify the electric field. The counter electrodes such as the collection or precipitator electrodes may comprise at least one of the cell walls and the inlet or region around the inlet to the pelletizer. The ESP power supply such as a high voltage power supply may apply a high negative voltage to the central electrode such as the wire electrode, and the collection electrodes such as at least one of the cell walls and inlet may be grounded. The particles such as ones comprising silver become positively charged and are collected on the negative wire or rod. In an alternative embodiment, the high voltage power supply may apply a high positive voltage to the central electrode such as the wire or rod electrode, and the collection electrodes such as at least one of the cell walls and inlet may be grounded such that the positively charged silver particles collect on the cell walls and inlet. (The opposite occurs for the two cases, when the particles are negatively charged.) The collected particles may be transported to the inlet to the pelletizer. The transport may by at least one of gravity, electrostatic fields, electromagnetic fields, and mechanically. Alternatively, at least one electrode may comprise at least one wire (88 of FIGURE 2123), wire gauze (89 of FIGURE 2123), or a wire mesh that is substantially non-blocking of the emission of the cell to the PV converter. The electrodes may comprise a refractory conductor such as a refractory metal such as Mo or W such that cooling may be achieved predominantly by radiation. In an exemplary embodiment, a central wire was charged negatively to between 500 V and 1500 V while two counter electrode plates at a radius of 10 cm were grounded. The cell pressure was about 30 to 50 mTorr. Positively charged silver particles were electrostatically collected at 50 mA on the negative central electrode. The particles were neutralized upon contacting the central wire, and the neutralized sliver particles fell by gravity to a collector. The electric field strength may be increased to provide a higher ESP force and ESP effect by decreasing the spacing of the electrodes, and by increasing the applied ESP electrode voltage. The time of action and the ESP effect may be increase by increasing the vertical length of the electrodes along the trajectory of the ignition products.

In an embodiment, the cell 26 may comprise a transmission line or waveguide designed to have impedance that reflects the plasma and particles at a desired distance from the blast region based on the impedance matching of the plasma medium for propagating alternating frequency power along the cell. The alternating frequency may be characteristic of the ignition waveform that may be controlled. The dimensions of the cell may be controlled. The controls may facilitate plasma power propagation into a region of the cell until the impedance for the plasma power propagation is no longer matched to the cell impedance. The plasma impedance may be controllably changed through the conductivity of the plasma that may drop along the propagation path due to ion-electron recombination. The plasma propagation may be halted or reflected. The recovery of the ignition products may be at least partially facilitated by the halting or the reflection of the plasma.

At least one polarity of electrode may comprise a UV mirror surface such as those of the disclosure such as MgF ₂ coated Al to at least one of reflect the emission of the cell and prevent the ignition product from adhering. In the latter case, another anti-adhering coating comprises sapphire. In another embodiment, the walls may comprise aluminum foil such as Al foil that may comprise a thin protective oxide coat as an anti-adhering surface. The walls may comprise at least one of molybdenum such as Mo foil with an oxide coat, tungsten carbide (WC), WC coated metal such as WC-coated Mo or W, tungsten, Ta, Nb, TaW, carburized metal such as steel or related alloys, anodized aluminum, alumina such as alpha alumina that may be sputter coated on a substrate such as stainless steel, graphite, Grafoil, graphene, and graphite coated conductor such as graphite coated Cu, Mo, or W as an anti- adhesion material. In an embodiment, the walls may comprise carbon-coated support such as a ceramic or metal support. The carbon may comprise graphite. The graphite may be applied by means known in the art such as a liquid spray that is cured on the support. Other means comprise vapor deposition, sputtering, chemical deposition, and others known in the art. The walls may comprise a support such as a metal coated with graphite that may be pyrolytic graphite. The coating may be with pyrolytic graphite tiles. The coating may be boron carbide (e.g. B ₄ C), fluorocarbon polymer such as Teflon (PTFE), zirconia + 8% yttria, Mullite, Mullite-zirconia, or Mullite-yttria stabilized zirconia (YSZ) that may operate at high temperature. The coating such as one on high-temperature stainless steel or copper may comprise anodized aluminum. The aluminum may be applied by coating methods known in the art such as thermal spray or arc spraying and electroplating. The aluminum coating may be anodized. The anodization may be performed in an electrolysis cell such as one comprising a sulfuric acid electrolyte. In an embodiment, the cell walls such as ones comprising surfaces that resist wetting or adhesion of the ignition product may be angled or tilted from the direction of the propagation trajectory of the ignition product particles to facilitate the ignition product particles deflection from the walls without adhesion. At least one of the cell walls and cell top may comprise a corrugated surface of a material such a anodized aluminum or graphite that resists ignition product adhesion so that the ignition product particles such as molten Ag particles do not impact perpendicularly and adhere. In an embodiment, the walls may comprise a foil that may be stretched to absorb impact from particles from the blast to prevent them from embedding. In another embodiment, the foil may be angled relative to the blast direction to deflect the particles to avoid adhesion. In an embodiment, the walls may comprise different materials in order to provide desired selective capabilities such as heat resistance and reflection of UV light in desired cell regions. For example, the top portion of the cell walls nearer the PV converter may comprise MgF ₂ coated Al to reflected UV light, and the bottom portion of the cell walls at the electrodes and ignition product inlet may comprise graphite, Mo, or tungsten carbide to operate at high temperature. The high temperature of the bottom section of the walls may facilitate returning the ignition product close to or above its melting temperature to reduce the input energy to regenerate the fuel shot by the pelletizer. A hydrogen atmosphere, low oxygen partial pressure due to pumping, or an oxygen getter may protect the oxidizable components such as graphite and aluminum from oxidation. The same applies to oxidizable electrode

components.

The ESP system may further comprise a barrier electrode section to charge the particles. In an embodiment, at least one of the walls and surface to the photovoltaic (PV) converter may be positively charged to repel positively charged silver particles to prevent them from adhering to the cell wall or PV converter. The particles may be positively charged by a high voltage coronal discharge. In another embodiment, at least one of the walls and the surface of the photovoltaic (PV) converter may comprise a barrier electrode or may have a barrier electrode between the region of ignition and the wall or PV converter. The barrier electrode may be charged to the same polarity as the ignition product particles to repel them and prevent adhesion to the wall or converter surface. In an exemplary embodiment, the particles such as silver particles are positively charged, and the barrier electrode is positively polarized to repel the particles.

In another embodiment, eddy currents are induced in the particles by time-varying fields such as radio frequency fields that comprise excitation fields. The eddy currents may induce a field to be produced by the particles. The induced field may interact with the excitation field to cause the particles to undergo at least one of trapping and translation. The excitation field may be controlled to achieve a translation away from at least one of the cell walls and the PV converter to prevent adhesion. At least one antenna and RF generator may apply the RF field. The at least one antenna may comprise a set of electrodes. The antenna may comprise an RF coil. The coil and RF generator or power source may comprise an inductively coupled heater. To prevent adhesion on at least one of the cell wall and the PV converter, the coil may surround the region where the ignition product is desired to be confined. In an embodiment, a standing electromagnetic wave is maintained in an inductively coupled cavity formed by opposing antennae orientations that induces eddy currents in the metallic particles and traps them in the cavity. The trapping action of the radio frequency field on the particles reduces their velocities acquired from the ignition blast so that gravity may eventually make them drop to the bottom of the cell to be collected into the inlet of the pelletizer. The system to prevent particle adhesion may comprise an RF source and at least one antenna to induce eddy currents in the particles and may further comprise an applied field such as at least one of a static magnetic field and a static electric field. The static magnetic field may be applied by at least one of a permanent and an electromagnet. The static electric field may be applied by a set of electrodes and a power supply. The frequency of the antennae-excited electromagnetic trapping system may be in at least one frequency range of about 1 Hz to 100 GHz, 1 kHz to 10 GHz, and 100 kHz to 100 MHz. The frequency may be selected based on the particle size. A higher frequency may be applied for smaller particles. One skilled in the art may test different coil geometries, power, and frequency to achieve a force such as levitation of the metal powder ignition product or its expulsion from the top cell region.

In an embodiment, ionized particles of the plasma formed by ignition of the solid fuel are prevented from electrostatically adhering to surfaces of the cell such as the window of the PV converter, the PV converter, and the cell walls. In an embodiment comprising magnets such as 8c (FIGURE 2110) that produce a magnetic field perpendicular to the direction of the ignition and plasma current across the electrodes, at least a portion of the ionized particles are swept away from the window of the PV converter and the PV converter by the Lorentz force, and at least a portion of the remaining unionized particles do not electrostatically adhere to the surfaces due to their electrical neutrality. The neutral particles may elastically scatter from the surfaces. In an embodiment, the particles are further prevented from

electrostatically adhering to the surfaces by electrical neutralization by means such as grounding. The grounding may be achieved by using a conductor in contact with the un- neutralized particles. The material may have at least one of the characteristics of a low work function, high surface area, high thermionic activity, and high photoelectric activity. The material may comprise a metal that is cessiated. In an embodiment, a means to neutralize the charged particles such as positively charged particles comprises a source of neutralizing electrons such as at least one an electrical ground path and free electron injector. The injection of free electrons may be by means such as an electron beam and a photocathode. The photocathode may emit photoelectrons due to the illumination with the appropriate high- energy light from the plasma. The photocathode may be one of the disclosure such as GaN. Neutralization may also be achieved by using a heated filament that emits electrons when heated such as a W or thoriated W filament. A positive bias may be applied between an accelerating grid and the filament to improve the amount of current injected into the plasma to neutralize it.

In an embodiment, at least one of the photovoltaic (PV) cells and panels are tilted away from being in the transverse plane to the propagation direction of the particles from the ignition of the solid fuel shots. The array of at least one of the PV cells and panels may be arranged as a Venetian blind such that the moving particles from the ignition graze them at an angle. In an embodiment, the grazing incidence prevents the particles from adhering to the at least one of the PV cells and panels. The particles may elastically scatter. Small particles have a high surface tension to form spheres that may facilitate the elastic scattering and non- adherence. The tilted PV cells and panels may elastically deflect or scatter the particles to a non-adhering surface such as a graphite, aluminum, zirconium, or WC surface. The non- adhering surface may comprise vertical slats connecting the upper edge of one member and the lower edge of a contiguous member of the array arranged as a Venetian blind

configuration. The particles may drop or be transported from the non-adhering surface to the inlet of the pelletizer. The grazing incidence feature of the PV converter may be applied in combination with other methods of the disclosure to prevent adhesion of the particles such as the use of crossed current such as ignition current and magnetic fields applied by magnets to cause a Lorentz force deflection of the particles, and the PV cells may be each coated with an non-adhering surface such as aluminum. In an embodiment, the tiled or Venetian blind PV configuration may increase the surface area of the PV converter to permit higher power output.

In an embodiment, the plasma and plasma emission are incident each of a series of mirrors such as UV mirrors of the disclosure at shallow incidence angle. The shallow or grazing angle results in a much higher reflection coefficient than that of a more normal incidence angle. The series of mirrors selectively separates the light from the particles. The particles may undergo inelastic collisions with the mirrors to be removed from the plasma while the light is reflected through the series of mirrors to be directed onto the PV converter. The particles comprising the solid fuel ignition product are collected at the inlet to the pelletizer. The collection may be by gravity flow or other means of the disclosure.

In another embodiment, the collection electrode may comprise a mechanical transporter such as a bucket elevator. Alternatively, the transporter may comprise a conveyor belt wherein the powder may adhere electrostatically and be transported mechanically to the pelletizer. Charged electrodes may generate an electrostatic field that induces a mirror dipole in the conducting particles and holds the particles on the belt electrostatically by the charge and induced charge interaction. The belt may be charged by the mechanism of a van de Graaf generator. The conveyor may comprise a van de Graaf generator. Alternatively, the fields may be created with current carrying wires that alternate in current direction and are embedded in an insulator. Such a transporter is well known in the art of photocopying wherein an electrostatic binding plate binds and transports paper that has an oppositely induced polarization charging. The powder may be released where desired such as into the pelletizer by discharging the fields. The discharge may be achieved with illumination as in the case of the selenium plate of photocopying technology. In another embodiment, particles may adhere to a magnetized conveyor such as one comprising a belt that comprises surface electrodes that supply current through the particles when in contact with the conveyor surface. The particle current gives rise to a particle magnetic field that interacts with the magnetization of the conveyor belt to cause the particles to adhere. The particles may be released by terminating the current through the conducting particles. In both the electrostatic and magnetic embodiments, the particle may fly off of the belt due to the centrifugal force at top belt rollers. They may also be mechanically removed with a scraper for example. In an embodiment, the mechanical transporter such as the conveyor belt may replace the railgun injector shown in FIGURE 216 wherein fuel shot replaces the particles of the present disclosure.

The stationary electrodes 8 of FIGURES 2110-2123 may be shaped to cause the plasma and consequently the light emitted for the plasma to be projected towards the PV converter 26a (FIGURE 212). The electrodes may be shaped such the molten fuel initially flows through a first electrode section or region 8i (FIGURE 2112) comprising a neck or narrower gap to second electrode section or region 8j having a broader gap. Ignition preferentially occurs in the second section 8j such that plasma expands from the second electrode section 8j towards the PV converter 26a. The necked section may create a Venturi effect to cause the rapid flow of the molten fuel to the second electrode section. In an embodiment, the electrodes may comprise a shape to project the ignition event towards the PV converter, away from the direction of injection. Suitable exemplary shapes are a minimum energy surface, a pseudosphere, a conical cylinder, an upper sheet parabola, an upper half sheet hyperbola, an upper half sheet catenoid, and an upper half sheet astroidal ellipsoid with the apex truncated as a suitable inlet comprising the first section. The electrodes may comprise a surface in three dimensions with a split that may be filled with insulation 8h between half sections (FIGURE 2112) to comprise the two separated electrodes 8 having an open circuit gap 8g. The open circuit is closed by injection of the melt shot causing contact across the conductive parts of the geometric form comprising the gap 8g. In another embodiment, the electrodes may comprise a rectangular section of the three- dimensional surface that is split. In either embodiment, the split 8h may be formed by machining away material such that the geometric form remains except for the missing material comprising the split 8h. In an embodiment, the velocity of the shot may be controlled to be sufficient to cause the plasma and emitted light to be in region 81 directed to the PV converter 26a.

In an embodiment, the injector 5zl is designed to limit the heat transfer rate from the plasma to the injector such that the water at its flow rate to sustain a desired power from the hydrino process does not boil while within the injector. The injector 5zl may comprise i.) a minimum surface area, ii.) material of low heat transfer rate, iii.) surface insulation, and iv.) radiation shields to limit the heat transfer to the flowing water. In an exemplary embodiment wherein the hydrino reaction is H ₂ O to H ₂ (l/4) + l/2O ₂ + 50 MJ, the minimum water flow rate to generate X watts of power is given by

Flow Rate = (X watts/50 MJ/mole H ₂ O) X (1 liter H ₂ O /55 moles) (39)

In the exemplary case wherein X = 500 kW, the flow rate is 0.18 ml/s. The power to cause 0.18 ml per second of water to boil from an initial temperature of 0 °C is 490 W. Thus, the injector 5zl is designed such that its maximum rate of acceptance of heat from the cell such as from the plasma corresponds to a power of less than 490 W. Using the relation:

wherein P is the pressure, p is the density of water, and v is the velocity, a water injection pressure of 3 atm corresponds to a nozzle 5q flow rate of 25 m/s. The size of the orifice of the nozzle 5q to deliver 0.18 ml/s (0.18 X 10 ^-6 m ³ ) at this flow rate is 7.2 X 10 ^-9 m ² (95 um diameter disk). Given a tube of twice this diameter with 3 cm immersed in the plasma, the plasma contract area of the tube is 1 X 10 ⁵ m ² which requires that the heat transfer rate be less than 490 W/ 1 X 10 ⁵ m ² or 4.9 X 10 ⁷ W I m ² .

In an embodiment, micro-water droplets such as in the range of 0.1 to 100 um diameter may be formed by an aerosolizer such as an ultrasonic aerosolizer. The ultrasonic frequency may be high such as in a range of about 1 kHz to 100 kHz. The aerosolization may result in the formation of ice crystals. The water may be injected into vacuum. The expansion into vacuum may cool the water to form ice. The evaporation of the water injected into vacuum may form the ice. The evaporation may cool the tip of the injector 5zl that may cause the injected water to form ice. At least one of the injected water and tip may be cooled by chiller 31a. The cooling may be to a temperature that results in ice crystal formation of the injected water while preventing the tip from icing up and clogging.

The open circuit is closed by injection of the melt shot causing contact across the conductive parts of the gap 8g only in the bottom layer. In an embodiment, the shot may be delivered along the y-axis. The nozzle 5q may deliver the shot horizontally along the y-axis to the top of the electrodes (FIGURES 2117 and 2118). The light may constrained to predominantly propagate upward due to an electrode design that permits the plasma from the ignited top-loaded shot to expand predominantly in the positive z-direction along the z-axis towards the PV converter 26a.

In a tested embodiment, the shot injection rate was 1000 Hz, the voltage drop across the electrodes was less than 0.5 V, and the ignition current was in the range of about 100 A to 10 kA.

Magnets such as 8c of FIGURES 2117 and 2118 may cause plasma particles such as those from the shot ignition to be directed away from the region 8k (FIGURE 2112). In an exemplary embodiment wherein the Lorentz force is directed in the negative z-axis direction, the magnets and channel 8g comprises an electromagnetic pump that performs at least one function of (i) injecting shot in region 8j into the gap 8g to be ignited, (ii) pumping shot that has adhered to the upper part of the electrodes such as at region 8j into the gap 8g to be ignited, (iii) ejecting un-ignited shot and particles from the region 8i and the gap 8g and (iv) recovering the ignition product and un-ignited shot to the pelletizer. The ejection and recovery may be by the Lorentz force formed by a crossed applied magnetic field such as that from magnets 8c and ignition current through at least one of the plasma particles and shot such as silver shot adhering to the electrode surfaces such as 8i, 8g, and 8j . The ignition current may be from the source of electrical power 2 (FIGURE 2110).

Consider the Cartesian coordinates with the z-axis from region 8k to 81 of FIGURE 2112. In an embodiment, the electrodes may comprise an upward (positive z-axis oriented) V-shape with a gap at the 8g at the bottom of the V (FIGURES 2117 and 2118). The open circuit may be closed by injection of the melt shot 5t from nozzle 5q causing contact across the conductive parts of the gap 8g at the bottom of the V. The V may be formed by flat plate electrodes mounted on opposite faces of supports that form a V with a gap at the bottom. Exemplary electrode materials comprising a conductor that operates a high temperature and resists adhesion of Ag are W, WC, and Mo. The supports may be water-cooled. The supports may be a least partially hollow. The hollow portions may each comprise a conduit for coolant that flows through the conduits and cools the electrodes.

In an embodiment, the electrodes may further comprise a lower section having vertical walls or near vertical walls at the gap 8g. The walls may form a channel. In an embodiment, the electrodes further comprise a source of magnetic field such as a set of magnets at opposite ends of the channel of the electrodes. The magnets may produce a magnetic field parallel to the electrodes or channel axis and perpendicular to the ignition current. The channel with crossed current and magnetic field may comprise an

electromagnetic (EM) pump. The EM pump may pump adhering shot into the electrodes to be ignited. In an embodiment, the Lorentz force due to the crossed magnetic field and ignition current may at least one of pump the shot adhering to the walls of the upper portion of the electrode downward to be ignited and pump ignition particles downward away from the PV converter to be recovered in the inlet to the pelletizer. In an exemplary embodiment, the shot 5t may be injected horizontally long the y-axis, on top of the V-shaped electrodes 8 (FIGURES 2117 and 2118). In an embodiment, magnets 8c are positioned to apply a magnetic field along the y-axis, along the trough of the V-shaped electrodes 8. The circuit is closed and x-axis-directed ignition current flows by shot providing a current path across the gap 8g wherein the magnetic field is transverse to the current. The crossed current and magnetic field create a Lorentz force according to Eq. (37) to push out any metal shot adhering to the electrodes. The Lorentz force may further push the ignition particles downward to region 8k (FIGURE 2112) to recover un -ignited shot and to recover ignition particles. The Lorentz force causes the flow of the adhering shot into the ignition section of the electrodes at the gap 8g and causes the ignition plasma to be directed and flow into a collection region such as inlet of the fuel regeneration system such as the pelletizer. In other embodiments of the disclosure, the electrodes and magnets may be designed to direct the plasma in an upward arch to perform at least one function of (i) injecting shot in region 8i into the gap 8g to be ignited, (ii) ejecting shot that has adhered to the upper part of the electrodes such as at region 8j, (iii) ejecting un-ignited shot and particles from the regions 8i, 8j, and the gap 8g and (iv) recovering the ignition product and un-ignited shot to the pelletizer, while avoiding guiding ignition particles to the PV converter 26a.

In an embodiment, the shot is delivered along the y-axis (FIGURES 2117 and 2118). The nozzle 5q may deliver the shot horizontally along the y-axis to the top of the electrodes. The solid fuel may be delivered as a stream of shots, a continuous stream, or a combination of shot and a stream. The light may constrained to predominantly propagate upward due to an electrode design that permits the plasma from the ignited top-loaded shot to expand predominantly in the positive z-direction along the z-axis towards the PV converter 26a. The electrodes may further comprise at least one magnet such as a set of magnets 8c separated at opposite ends of the electrodes to produce a magnetic field in a direction perpendicular to the ignition current. The Lorentz force due to the crossed current and magnetic field may cause the ejection of adhering shot and the flow of the plasma particles to the regeneration system such as the pelletizer. The Lorentz force may be in the negative z-direction. In the case that the Lorentz force is in the negative z-direction, a region, section, or layer such as the ignition layer of the electrodes 8 may comprise a channel that may act as an electromagnetic pump for the ejection of ignition particles and shot that is not ejected as particles and plasma. The size of the channel may be selected to provide flow restriction to the high pressure expanding ignition plasma that forces the plasma and light to expand towards the region 81 of the electrodes (FIGURE 2112). The ignition portion of the electrodes may form a shallow channel comprising a short electromagnetic pump tube such that the particles and adhering shot fills the pump tube and restricts the path for the emitted light to be only along the positive z-axis. The strength of the crossed current and magnetic field and well as the dimensions of the channel provide the pump pressure through the channel comprising the electromagnetic pump tube. The width of the pump tube and any splay are selected to distribute the current from the source of electrical power 2 for ignition and pumping to achieve optimization of both.

In the case that the shot is injected on the same side as that desired for the expansion of the plasma such as side 81, the source of electrical power may deliver the ignition current without substantial time delay. The injection may be timed to avoid the n +1 th injection from being disrupted by the pressure wave from the ignition blast of the nth injection wherein n is an integer. The timing may be achieved with blast and injection sensors such as at least one of optical, current, voltage, and pressure sensors and a controller. The controller may control at least one of the electromagnetic pump pressure, the nozzle valve, and the ignition current.

In case of shared lines, the area of contact of the line with the electrode may be adjusted depending on the average local coolant temperature to achieve efficient heat transfer from the electrode to the coolant. In another embodiment shown in FIGURE 2123, the electrodes and bus bars of the ignition system may be cooled by a passive cooling system 3 lh comprising a heat exchanger such as one comprising air fins and optionally heat pipes to the air fins. In an embodiment shown in FIGURE 2123, the photovoltaic conversion system may also be cooled by a passive cooling system 3 li comprising a heat exchanger such as one comprising air fins and optionally heat pipes to the air fins. In an embodiment shown in FIGURE 2122, the photovoltaic (PV) cells or panels 15 of the photovoltaic converter 26a are cooled with heat exchanger 87 wherein the hot coolant flows into the photovoltaic converter cooling system 31 through inlet 31b and chilled coolant exits through outlet 31c.

The ejection velocity may be controlled to compensate for the deceleration of gravity to maintain a desire injection rate. The height of the nozzle 5q may be adjusted to support a maximum injection rate. The maximum height may be based on the rate a stream of fuel melt forms isolated spheres or melt shot. In an embodiment, the SF-CIHT generator comprises a user interface such as a touch-screen display of a computer to control the generator further comprising a computer with sensors and control systems of the injection system, the ignition system, the fuel recovery system, the fuel regeneration system such as the pelletizer, and the converter system such as at least one of the photovoltaic and photoelectron converter system. The a computer with sensors and control systems may sense and control the electromagnetic pump, inductively coupled heaters, injector flow, nozzle, ignition system current and pulse rate, product recovery system such as applied magnets and currents and electrostatic precipitator (ESP), photovoltaic (PV) converter system, cooling systems, power conditioning and other system monitoring and controls to operate the generator known by those skilled in the art.

In an embodiment, a parameter to be measured may be separated from a region of the system that has an elevated temperature that would damage the sensor during its measurement. For example, the pressure of a gas such as at least one of H ₂ and H ₂ O may be measured by using a connecting gas line such as a cooling tower that connects to the cell such as 5b or 5c and cools the gas before entering a pressure transducer such as a Baratron capacitance manometer.

The cell may comprise few to no or moving parts. In an embodiment, the cooling may comprise heat rejection to an air-cooled heat exchanger. Exemplary, air-cooled systems for the electrodes 3 lh and PV conversion system 3 li are shown in FIGURE 2123. In this case, the cell may comprise no or very few moving parts. The only moving part may comprise a mechanical pump to circulate coolant, and it may be replaced with one with no moving parts. In the case that the coolant is a liquid metal such as an alkali metal such as sodium, the pump may comprise an electromagnetic pump that may have no moving parts. In an embodiment, the electromagnetic pump coolant may be nonflammable. Alternatively, heat pipes and air fins or Peltier chillers may be used to remove the heat as a means of non- mechanical heat rejection. Exemplary heat pipes are a copper heat pipe with soldered longitudinal copper fins using water or acetone as the working fluid and an aluminum heat pipe with soldered longitudinal aluminum fins using ammonia as the working fluid. The source of heat may be the ignition electrodes wherein the heat may be rapidly conducted away from the electrode surface to the cooling system by large cross section thermal bus bars 9 and 10 comprising highly thermal conductive material such as copper, silver, or a silver- copper alloy. The source of heat may also comprise the PV converter.

The mechanical vacuum pump may also be replaced to eliminate it as a system with moving parts. In an embodiment, the vacuum in the cell may be maintained by at least one getter 13b (FIGURE 2123) such as at least one for oxygen, hydrogen, and water. An oxygen getter such an oxygen reactive material such as carbon or a metal that may be finely divided may scavenge any oxygen formed in the cell. In the case of carbon, the product carbon dioxide may be tapped with a CO ₂ scrubber that may be reversible. Carbon dioxide scrubbers are known in the art such as organic compounds such as amines such as monoethanolamine, minerals and zeolites, sodium hydroxide, lithium hydroxide, and metal- oxide based systems. The finely divided carbon getter may also serve the purpose of scavenging oxygen to protect oxygen sensitive materials in the cell such as vessels or pump tube comprising oxygen sensitive materials such as Mo, W, graphite, and Ta. In this case, the carbon dioxide may be removed with a CO ₂ scrubber or may be pumped off with the vacuum pump where fine-divided carbon is used solely for component protection.

In an embodiment, a medium other than standard ones such as water or air may be used as the working medium of the heat engine. In exemplary embodiments, a hydrocarbon may replace water in a Rankine cycle of a turbine-generator, and supercritical carbon dioxide may be used as the working medium of Brayton cycle of a turbine-generator. Alternatively, the hot cover 5b4 may serve as a heat source or a heater or a light source. The heat flow to the heat engine or heater may be direct or indirect wherein the SF-CIHT generator may further comprise a heat exchanger or heat transfer means such as one of the disclosure.

At least one of the cell chamber 5b3 and the reaction cell chamber comprising the chamber formed by the cone 5b2 and top cover 5b4 may be evacuated with pump 13a through pump lines 13b and 13c, respectively. Corresponding pump line valves 13d and 13e may be used to select the pumped vessel. The cell may further comprise a high temperature capable sensor or sensors for at least one of oxygen, hydrogen, water vapor, metal vapor, and total pressure. The water and hydrogen pressure may be controlled to a desired pressure such as one of the disclosure such as a water vapor pressure in the range of 0.1 Torr to 1 Torr by means of the disclosure. In an exemplary embodiment, the desired gas pressure is maintained by a valve and a gas supply wherein the valve opening is controlled to supply a flow to maintain the desired pressure of the gas with feedback using the measured pressure of the gas. The H ₂ O and H ₂ may be supplied by hydrogen tank and line 5u that may comprise an electrolysis system to provide H ₂ , H ₂ O/steam tank and line 5v, hydrogen manifold and feed line 5w, H ₂ O/steam manifold and feed line 5x, H2/steam manifold 5y, direct H ₂ O/H ₂ injector 5zl, and direct H ₂ O/H ₂ injector valve 5z2. Oxygen produced in the cell may be reacted with supplied hydrogen to form water as an alternative to pumping off or gettering the oxygen. Hydrino gas may diffuse through the walls and joints of the cell or flow out a selective gas valve.

The metal vapor in the sealed reaction cell chamber 5b31 may coat the cell walls to suppress vaporization and migration of the wall material. In an embodiment, a surface such as an inner cell surface may be initially coated with a material such as a coating of the disclosure, a metal, or another metal having a lower vapor pressure than the material of the surface. For example, a Mo cone may be internally coated with W to lower the internal Mo vapor pressure. The coating may further protect the surface from at least one of oxidation and evaporation of the material of the surface. A composition of matter such as a gas may be added to the reaction cell chamber 5b31 atmosphere to stabilize or regenerate at least one surface in the cell. For example, in the case that at least one of the cone 5b2 and the top cover 5b4 comprise tungsten, iodine gas may be added to the reaction cell chamber 5b31 atmosphere to cause W to redeposit on at least one of the W cone 5b2 and W top cover 5b4 surfaces. The external surfaces of the cone 5b2 and top cover 5b4 may similar be

regenerated. The cone reservoir 5b may be operated at a lower temperature than at least one of the top cover 5b4 and cone 5b2 to cause the metal vapor of the fuel melt to condense in the cone reservoir 5b to supply the regeneration of the fuel such as one comprising injected molten fuel metal and at least one of H ₂ O and H ₂ . At least one of the reaction cell chamber 5b31 and the cell chamber 5b3 housing the cell 26 may be operated under vacuum to prevent oxidation of the cell components such as the cone 5b2 and top cover 5b4. Alternatively, at least one of the reaction cell chamber 5b31 and the cell chamber 5b3 may be filled with an inert gas to prevent at least one of oxidation and evaporation of the cone 5b2 and the top cover 5b4. In an embodiment, the metal vapor from the fuel melt coats the inner surfaces of the reaction cell chamber 5b31 and protects them from oxidation by the H ₂ O fuel. As given in the disclosure the addition of H ₂ gas or the application of a negative voltage to the cell components such as the cone 5b2 and top cover 5b4 may reduce or avoid their oxidation. The top cover 5b4 may comprise the material of an incandescent light bulb such as tungsten or tungsten-rhenium alloy. The inert gas may be one used in an incandescent light bulb as known by those skilled in the art. The inert gas may comprise at least one of a noble gas such as argon, krypton, or xenon, and nitrogen, and hydrogen. The inert gas may be at reduced pressure such as a pressure used in an incandescent bulb. The inert gas pressure may be in the range of about 0.01 atm to 0.95 atm. In an embodiment wherein the metal of the top cover 5b4 such as Mo or W is transferred by evaporation and deposition to another cell component such as the outer wall of the cone 5b2, the cell chamber that houses the cell, and a component of the PV converter 26a, the metal such as a metal coating maybe be removed and recycled by exposing the coating to oxygen and collecting the metal oxide. The oxygen exposure may be at an elevated temperature. A metal coating on the PV panels 15 may be cleaned by exposing the panel surface to oxygen and cleaning off the metal oxide.

All particles independent of size and density experience the same gravitational acceleration. In an embodiment, the reaction cell chamber 5b31 is operated under vacuum or the absence of cell gas other than fuel such as water vapor such that metal vapor particles may be confined to a desired region of the reaction cell chamber 5b31 by the effect of gravity. The region may comprise the electrode region. In another embodiment, the reaction cell chamber 5b31 is operated under a partial vacuum with a heat transfer gas present to cause the metal vapor to form particles that fall under the force of gravity to cause confinement of the metal vapor. The confinement may be to the electrode region. The heat transfer gas may comprise hydrogen or an inert gas such as a noble gas such as helium that comprises a high heat transfer agent. The pressure of the heat transfer gas may be adjusted to achieve the desired confinement. The desired confinement condition may comprise a balance of the effects of aerosolization by the gas and gravity.

In another embodiment, the reaction cell chamber 5b31 is operated under an inert atmosphere. The inert gas may have a lower density than the metal vapor of the solid fuel melt such as the vapor from molten Ag or Ag-Cu. Exemplary lower density inert gases are at least one of hydrogen and a noble gas such as at least one of helium or argon. The metal vapor may be confined to the electrode region of the parabolic reflector dish 5b2 due to the presence of the more buoyant inert gas. The difference in densities of the metal vapor and the inert gas may be exploited to control the extent of the confinement such as the volumetric displacement of the metal vapor. At least one of the selection of the inert gas based on its density and the pressure of the inert gas may be controlled to control the confinement of the metal vapor. The SF-CIHT generator may comprise a source of inert gas such as a tank, and at least one of a pressure gauge, a pressure regulator, a flow regulator, at least one valve, a pump, and a computer to read the pressure and control the pressure. The inert gas pressure may be in the range of about 1 Torr to 10 atm. In an embodiment, any atmospheric convection currents due to temperature gradients in the atmosphere of the reaction cell chamber 5b31 may be formed to favor a desired confinement of the metal vapor. The cone reservoir 5b may be cooler than the metal vapor and other proximal cell components in contact with the metal vapor such as the parabolic reflector dish 5b2. The gas convection current may be towards the cone reservoir 5b due to its lower operating temperature. The metal vapor may condense in the cone reservoir 5b to enhance the vapor flow direction towards the cone reservoir 5b and increase the metal vapor confinement. The cone reservoir 5b2 may be cooled. The coolant coil comprising the antenna of the inductively coupled heater 5f may be used to cool the cone reservoir 5b, or it may be cooled by a separate cooling coil or heat exchanger. In the case that heat is removed through the reservoir 5c, the corresponding thermal power may be controlled by controlling the heat gradient along the reservoir 5c and its cross sectional area. A schematic of the inductively coupled heater feed through assembly 5mc is shown in FIGURES 2124-2126. The inductively coupled heater comprises leads 5p that also serve as coolant lines connect to a chiller 31 through inductively coupled heater coolant system inlet 5ma and inductively coupled heater coolant system outlet 5mb. In an embodiment, the inductively coupled heater coil leads penetrate into a sealed section of the generator such as at least one of the cell 26 or the lower chamber 5b5. The lead 5p penetrations of a wall to the cell component that is heated such as at least one of the penetrations of the flange of the inductively coupled heater feed through assembly 5mc and the penetrations of the lower vacuum chamber 5b5 may be electrically isolated such that the leads 5p do not electrically short.

In an embodiment, the confinement of the metal vapor may be controlled by forced gas flow using at least one blower as given in the disclosure for metal powder. In another embodiment, the metal vapor may be confined by flowing a current through the vapor using a current source and by the application of magnetic flux to cause a Lorentz force towards the cone reservoir 5b as given in the disclosure. In another embodiment, the metal vapor may be confined with an electrostatic precipitator as given in the disclosure.

In an embodiment, following startup the heater may be disengaged, and cooling may be engaged to maintain the cell components such as the cone reservoir 5b, EM pump, electrodes 8, cone 5b2, window 5b4, and PV converter 26a at their operating temperatures such as those given in the disclosure.

The SF-CIHT cell power generation system includes a photovoltaic power converter configured to capture plasma photons generated by the fuel ignition reaction and convert them into useable energy. In some embodiments, high conversion efficiency may be desired. The reactor may expel plasma in multiple directions, e.g., at least two directions, and the radius of the reaction may be on the scale of approximately several millimeter to several meters, for example, from about 1 mm to about 25 cm in radius. Additionally, the spectrum of plasma generated by the ignition of fuel may resemble the spectrum of plasma generated by the sun and/or may include additional short wavelength radiation. FIGURE 3 shows an exemplary the absolute spectrum in the 5 nm to 450 nm region of the ignition of a 80 mg shot of silver comprising absorbed H ₂ and H ₂ O from gas treatment of silver melt before dripping into a water reservoir showing an average optical power of 527 kW, essentially all in the ultraviolet and extreme ultraviolet spectral region. The ignition was achieved with a low voltage, high current using a Taylor- Winfield model D-24-75 spot welder. The voltage drop across the shot was less than 1 V and the current was about 25 kA. The high intensity UV emission had a duration of about 1 ms. The control spectrum was flat in the UV region. In an embodiment, the plasma is essentially 100% ionized that may be confirmed by measuring the Stark broadening of the H Balmer a line. The radiation of the solid fuel such as at least one of line and blackbody emission may have an intensity in at least one range of about 2 to 200,000 suns, 10 to 100,000 suns, 100 to 75,000 suns.

The UV and EUV spectrum may be converted to blackbody radiation. The conversion may be achieved by causing the cell atmosphere to be optically thick for the propagation of at least one of UV and EUV photons. The optical thickness may be increased by causing metal such as the fuel metal to vaporize in the cell. The optically thick plasma may comprise a blackbody. The blackbody temperature may be high due to the

extraordinarily high power density capacity of the hydrino reaction and the high energy of the photons emitted by the hydrino reaction. The spectrum (100 nm to 500 nm region with a cutoff at 180 nm due to the sapphire spectrometer window) of the ignition of molten silver pumped into W electrodes in atmospheric argon with an ambient H ₂ O vapor pressure of about 1 Torr is shown in FIGURE 4. The source of electrical power 2 comprised two sets of two capacitors in series (Maxwell Technologies K2 Ultracapacitor 2.85V/3400F) that were connected in parallel to provide about 5 to 6 V and 300 A of constant current with

superimposed current pulses to 5kA at frequency of about 1 kHz to 2 kHz. The average input power to the W electrodes (1 cm X 4 cm) was about 75 W. The initial UV line emission transitioned to 5000K blackbody radiation when the atmosphere became optically thick to the UV radiation with the vaporization of the silver by the hydrino reaction power. The power density of a 5000K blackbody radiator with an emissivity of vaporized silver of 0.15 is 5.3 MW/m ² . The area of the observed plasma was about 1 m ² . The blackbody radiation may heat a component of the cell 26 such as top cover 5b4 that may serve as a blackbody radiator to the PV converter 26a in a thermophotovoltaic embodiment of the disclosure.

In an embodiment, the converter comprises a plurality of converters that are ganged to comprise combined cycles. The combined cycle converters may be selected from the group of a photovoltaic converter, a photoelectronic converter, a plasmadynamic converter, a thermionic converter, a thermoelectric converter, a Sterling engine, a Brayton cycle engine, a Rankine cycle engine, and a heat engine, and a heater. In an embodiment, the SF-CIHT cell produces predominantly ultraviolet and extreme ultraviolet light. The converter may comprise a combined cycle comprising a photoelectron converter then a photoelectric converter wherein the photoelectric converter is transparent to ultraviolet light and may be primarily responsive to extreme ultraviolet light. The converter may further comprise additional combined cycle converter elements such as at least one of a thermoelectric converter, a Sterling engine, a Brayton cycle engine, and a Rankine cycle engine.

In an embodiment, the high current of the disclosure through the fuel activates the hydrino process without detonation. This aspect of the disclosure was confirmed

experimentally by applying 25 kA at a voltage drop of about 1 V across a Mo foil using a spot welder (Taylor- Winfield model D-24-75 spot welder, 75 KVA). A photoelectron effect was observed at a metal foil photocathode from UV emission in the absence of visible emission. The effect successively diminished to zero as the welder was repetitively activated. The result was attributed to residual hydrogen reacting to form hydrinos wherein the high current initiated the reaction. The dark nature of the effect indicated the selective emission of UV photons by the hydrino process to cause the photoelectron effect. The effect diminished as the hydrogen in the Mo foil was consumed or driven out by the applied welder power.

V. Other Applications In an embodiment, the output power of the SF-CIHT cell is emitted as electromagnetic radiation that is transmitted to a load by the load receiving the radiation with an antenna. The emission may be achieved by powering a transmitter with electrical power generated by the SF-CIHT cell. The radiation may be directional by using directional and aligned emitting and receiving devices such as antenna. In another embodiment, the power is transferred by induction such as magnetic induction. The magnetic induction may be at radio frequencies such as in the frequency range of about 1 kHz to 1 GHz, at any desired power level.
