Kind Code:
A1
Abstract:
Systems and apparatuses for delivering power and energy using deflecting beams or other oscillating members motivated to oscillate a beam assembly using an eccentrically balanced rotating body that induces deflections in the elastic beam or other oscillating member. One or more rotors may be used on the elastic beams and a mechanical output or outputs are connected to the elastic beams. The rotating body is advantageously maintained in rotation by pulses of electro-magnetic force. The oscillating beam or members are preferably driven at a natural resonant frequency to minimize losses and render more efficient the output which can be obtained. The pulse motor or motors can be powered using stored electrical energy, such as may be generated from solar panels, wind generators or other energy storage devices. One or more outputs may be used to drive heat pumps, compressors, pumps or other equipment to assist in independent energy systems.

Description:
SYSTEMS, APPARATUSES AND METHODS FOR THE TRANSMISSION AND

RECOVERY OF ENERGY AND POWER

BACKGROUND

[001] The efficient utilization of energy has been a long-felt need and while many individuals have tried to develop means to more efficiently utilize energy and produce power therefrom, there still exists a need for energy and power transformation systems which can serve a multitude of purposes and do so efficiently. There is also a need for systems which can store energy and have low transmission and/or storage losses.

[002] In attempting to solve the complex problems of efficient utilization and transformation of energy, power and related systems, various solutions have been tried. Recently, there has been a shift to the development of more sustainable and renewable resources for providing energy and converting energy into power. Accordingly, there has been a great deal of time and money spent on solar, wind and other energy and power production, generation, transmission, storage and other energy and power systems.

[003] Alternative forms of energy, such as solar and wind, seemingly have potential for being useful forms of energy generation. However, there still exist various impediments in effectively using these sources. They are still more costly than most systems generating power from fossil fuels, such as coal, oil, natural gas, and even oil and tar sands and shale. Additionally, the development of wind and solar power generation have inherent problems, such as they do not produce a consistent output. Thus, the use of fossil fuels and nuclear power remain the primary sources for the consistent provision of power because they can remain in essentially constant operation and are not subject to whether the wind may be blowing or the sun is shining.

[004] When energy is transformed, there is at least some and usually significant diminishment of output in relation to the initial input which is the result of the fact that a large amount of energy is lost as energy is transformed or merely transmitted. Thus minimizing energy loss as it goes through the transformation processes pose many significant and complicated challenges.

[005] Other longstanding problems which are associated with the generation, utilization, or other transformation or transmission of energy and power, are costly and there is typically a long time frame needed to conduct research and development. Such research and development usually results in very small efficiency gains at tremendous costs. Many of the developments in this field have taken decades; in addition, they are complex to operate and distribute power, resulting in a whole new set of challenges. Thus, the already complicated problem of efficiently generating and utilizing energy becomes increasingly complex and costly to develop.

[006] Although there has been a focus on creating systems which generate power and some which can store energy efficiently it has proved to be a great challenge to develop realistic and accessible solutions that at the same time are effective and reliable. This is even more particularly a problem in systems for homes and buildings as compared to large scale energy generation projects such as wind farms and large commercial solar generation complexes which may consume hundreds or thousands of acres of land. Even relatively constant output fossil or nuclear fuel power generation plants are often very large and expensive and are considered by many as undesirable for various reasons and produce undesirable byproducts. [007] Ironically, "clean" energy power production processes are now being challenged by some of the very same environmental groups that have demanded the development of alternative energy sources and power generation. Increasing criticism is being made of the unsightliness of large centralized power systems, such as wind farms and large scale solar powered electricity generation plants.

[008] The long-felt need for new and efficient energy systems continues. Research and development continues, as it has for about a century, along a multitude of different approaches in the valuable quest for efficient energy transformation systems which have greater economy and power production capability. Further complicating this is the fact that many other considerations and constraints may apply to any given production facility or situation.

[009] In addition to the above problems most current systems for the generation of electrical power involve generation at a large complex or industrial site. Such concentration of power generation requires relatively large transmission systems to deliver power to homes, businesses, industrial sites and other users of power. This may cause power to be distributed and transmitted over long distances with associated increased transmission and distribution losses. Although the current technologies utilize such large scale transmission systems to be more efficient, not only are they expensive, but also involve efficiency losses in transmission and are costly to build and require large initial investments. They also require substantial maintenance and pose large costs associated with getting the various permits and zoning changes which typically are needed.

[010] Another problem with large scale power production which use concentrated generation facilities and large transmission and distribution systems is that they are also more susceptible to terrorism attacks. A single power plant may provide sufficient power to supply cities. Most electrical power systems are interconnected in grids where power sources and loads can be controlled to balance demand and supply in response to changes or in reaction to more major problems, such as shutdowns in certain power generation facilities or because of faults or disruption in transmission and distribution systems. If attacks bring one or more generation facility, transmission system or distribution centers to a stop, then this may be sufficient to affect large geographical or population areas and cause power and consequential economic shutdowns.

[Oil] Such potential outages from terrorist attacks on large, concentrated systems may affect the availability or operation of other vital systems, such as water distribution, sanitation systems, information systems (such as the internet), even fuel supply systems all of which may be brought down at many attack points vulnerable to terrorism.

[012] Current systems may provide power for large areas and added safety from the malfunction of a single plant during times of heavy demand. A concerted effort by fanatical terrorists at many nodes of the national or international power grid could potentially render a wide scale shutdown of modern society because of its intense need for electrical power and the function of computer networks and the internet in complex optimization control systems which may require transfer of operational information over large areas being served and many facilities being coordinated. Thus, it may be more desirable to have decentralized power generation to reduce the risk of shutting down society due to terrorist attacks unless very costly measures are put into place.

[013] Large scale power systems currently in place have in some instances demonstrated the susceptibility of electrical power grids to failure. For example, the Northeastern U.S. and some parts of Canada experienced a multi-state power grid failure where the primary instigation of this failure was caused by the electrical generation and transmission system being subjected to very heavy load requirements from hot weather and the malfunction of a single plant which then caused consequential shutdowns at other facilities. These types of failures are demonstrative of the susceptibility of large scale centralized generation and distribution systems. Such incidents have happened more than once without terrorism being a factor. With the added risks of terrorism then the risks increase.

[014] Thus, smaller, distributed power generation systems may reduce the risk to society of fanatics or others who want to disrupt the generation and distribution of electrical power. This is in addition to the inherent risks of merely controlling and operating complex power systems.

[015] Most home power production systems are either fuel dependent, solar, or wind. The fuel capacity of small scale fuel systems is usually very small compared to what might be a long term outage. Solar systems for home and individual buildings are very susceptible to sunshine variations, due to regular natural processes such as day and night, cloud cover, seasonal fluctuations in incident solar radiation, or other possible vicissitudes of nature. Wind systems are equally or even more susceptible due to the fact they require the wind to blow. Battery storage may or may not be cost effective or cost prohibitive and may not provide the capacity to meet consumer demands during periods power cannot be produced from the sun or wind. This is particularly true when power is needed during sustained periods of time. Thus, solar and wind systems are often susceptible to intermittent operation and production of power. This may be soluble due to the rotation of the earth on a daily basis, but cloud formations and the absence of adequate wind are natural phenomena which can last for relatively long periods of days or weeks and thus severe damage to frozen food supplies, supplies of water and other facilities become very troublesome.

OVERVIEW OF SOME PREFERRED APPARATUSES

[038] The inventions may include deflecting members, such as elastically deformable beams or other structures having a rotating or other oscillatory body or bodies. In some preferred embodiments this is an eccentrically weighted rotating body or bodies mounted upon the deflecting members for inducing oscillation of the deflecting members. In some preferred embodiments the oscillations are induced at the natural resonance of the deflecting members.

[039] In some preferred embodiments the rotating body or bodies may have at least one magnet which is mounted on them. In addition, there is an electromagnetic pulse motor or other driver for sustaining movement of the oscillating. In some embodiments, an electromagnetic pulse motor is included which interacts by magnetic field and without contact with the rotor or rotor magnets. The pulsed magnetic drive provides intermittent pulses at a desired and preferably controlled time. As the driver magnet or magnets are pulsed with controlled magnetic fields the resulting torque applied to the rotor maintains rotation or other oscillation of the rotors.

[040] The amount of startup energy may be reduced by having the eccentrically weighted or other rotating body or bodies begin to rotate under the force of gravity and then maintain rotation with small consumption of electricity that is used to provide pulsed magnetic fields or other non-contacting torque inducers to maintain rotation or other oscillation inducing drivers. [041] The rotation of eccentrically weighted body or bodies causes the supporting members or beams to deflect and create an oscillating action and force. The oscillating action can be from a spinning weight or other suitable apparatuses.

[042] The mechanical output may be used to power one or more fluid working devices, such as a pump or compressor for pumping or compressing fluids, electromagnetic generators which generate current which may be stored in batteries, capacitors or other suitable apparatuses, or other means to store energy, now known or hereafter developed.

[043] The produced mechanical, electrical or other form of power can be used to power the pump or compressor for real time use, or be used to store energy in various forms for use at a later time to maintain a consistent or adequate power to be supplied. Water can be pumped in elevation to provide stored potential energy. Gases can be compressed to also store energy in the form of pressured gas.

[044] In some systems, a battery may be used as an energy storage device or devices for driving the oscillating mechanical force. The battery or other energy storage device may be powered by solar or wind electricity generators or other alternative input of power which can be stored and then used as a power source to generate electrical power used to maintain the oscillating system in motion.

[045] The description of specific apparatuses, systems and subsystems and methods included herein illustrate various embodiments according to this invention.

FIRST EMBODIMENT

[046] Fig. 1 shows a diagrammatic view of important parts of a first preferred system 100 according to a preferred embodiment of the inventions shown or described herein. The main parts of system 100 advantageously include a main support 110 which is used to support a beam assembly 120. The beam assembly moves, such as in an oscillatory action, when in operation.

[047] The beam assembly 120 oscillates in response to an oscillation inducing system 130. Oscillation inducing system 130 advantageously uses a rotating weight which is unbalanced relative to the center of rotation. The oscillation driver 140 may be powered by a battery 150 or other suitable source of power. As shown, the battery or batteries can be charged by a solar array 160 powered by the sun 170. The solar array can be made according to suitable technologies now known or hereafter developed. Other sources of energy or direct power are also possible in some forms of the invention.

[048] As shown, solar array 160 is electrically connected to supply electrical power to a controller 180 which distributes electricity as further explained below. Controller 180 is advantageously designed to control distribution of power to the battery. It may also be configured to have a second section 185 used to control delivery of electrical power to the oscillation driver 140 as will be more fully described below.

[049] The system of Fig. 1 also has an output 190. Output 190 is advantageously mechanically coupled to the beam assembly 120 for pivotal movement and functions by deriving power from the displacement of beam assembly 120. Output 190 may be used to drive different types of power consuming units (not illustrated in Fig. 1).

- Beam Support

[050] The beam support 110 is the primary support for the various parts of the system 100 and in particular is designed to support the beams 120 or other deflecting members and other portions of system 100. [051] Support 110 as shown is a column which may be suitably connected to mounting framework (not shown). The mounting framework may include a foundation or other supporting structure (not shown) used to support the lower or first end of the beam support 110. The opposing second end or upper portions of beam support or supports 110 are advantageously connected to a building which acts as a suitable superstructure. For example, the upper end may be supported by an elevated portion of the mounting framework, such as a ceiling joist of a building (not shown) or a brace or mainstay (also not shown).

[052] The framework is preferably made so as to mount the beam support 110 in a relatively rigid condition as compared to the deflecting members described in greater detail below. However, it may alternatively be suitable to have other frameworks which are hereafter determined or found suitable for the functions described herein.

[053] Mounted upon the beam support 110 are the deflecting members 120. Connections between the beam support and the beam assemblies or other deflecting members can be of various constructions. As shown in Fig. 1, the beam assembly connection is pivotal as described further below. Other alternatives some of which are described below may also be found suitable or preferred depending on the particulars of a given installation or further experimentation made hereafter.

[054] The beam support 110 can be made of a variety of suitably strong and preferably substantially rigid materials, such as concrete, steel, wood, fiberglass or various other materials suitable for the installation involved.

- Beam Assembly or Assemblies

[055] Fig. 1 shows one preferred version of the beam assembly 120 which forms a deflecting member. In this version the deflecting member or assembly is mounted in a cantilevered configuration upon support 110. The configuration also uses the oscillator connection in a position which is distal to the output 180 and thus forms a second degree lever arrangement. A top view of the apparatus is shown in Fig. 2 which depicts the deflecting members and the mounted rotating body and one possible way in which the apparatus may be constructed.

[056] In the embodiment of Fig. 1 the beam assembly is preferably a support advantageously in the form of a pair of beams in a parallel or substantially parallel relationship extending from the support in parallel or other suitable configuration depending on the geometry of the support and applied loads.

[057] In a single cantilever arrangement as shown in Fig. 1, and other configurations shown below it may alternatively be possible to have deflecting beams which may converge or be oriented relative to one another in non-parallel or specially shaped configurations to provide dynamic response capabilities which may be found advantageous in certain forms of the inventions according hereto. As shown, the beams 121 are arranged along opposing sides of support 110. They may be joined by cross members arranged and connected to tie the parallel beams 121 in a configuration which can be visualized as a ladder-shaped assembly. This is indicated by the cross members 122, 123 and 124.

- Connection of Beam Members to Support

[058] In Fig. 1 the two deflecting beam members 121 are shown to have connections to support 110 which are pivotal. The pivotal connections are advantageously provided on both front and rear sides of columnar support 110.

[059] As illustrated, the connections 112 have a bearing support piece or block 114 fixed to the beam. A pivot shaft 115 is provided which may be provided at each side or be mounted through the support column 110. Bearings 116, such as ball or roller bearings are provided to allow free angular displacement upon each side of the support to the beams forming parts of beam assembly 120.

[060] As further indicated herein other beam assembly connections may also be used. They can also be connected in any other suitable alternative way to the support at one or more couplings 112.

- Rotating Body

[061] Fig. 1 also shows that system 100 includes at least one rotating body 131. Rotating body 131 is shown in greater detail and in isolation in Fig. 3. The rotating body 131 has a head portion 133. Head portion 133 is connected to a pivot journal part 135 using an arm or swing arm 132. The journal part is advantageously provided with a shaft aperture 136. The journal part may be adapted to either mount a suitable bearing or a shaft extending through shaft aperture 136 may be mounted for rotation using a suitable bearing or set of bearings (not specifically shown) mounted in the rotating body mounting blocks 124.

[062] Rotating body 131 has an angularly varying non-uniform moment of inertia. This may be more simply termed as being imbalanced relative to the axis of rotation. This imbalance in the rotating body 131 causes the rotating body to accelerate under the force of gravity between the top dead center position shown in Fig. 1 and to decelerate from the dead bottom position of 180 degrees as it moves to the top dead center position. Thus the angular velocity of the rotating body will typically vary and in particular the angular movement of rotating body 131 varies in angular speed and/or otherwise.

[063] The mechanical force applied by the rotating body upon the supporting beam assembly 120 also may vary. At the top dead center position the vertical force carried by the beam assembly is the weight of the rotating body less the centrifugal force applied in an upward direction when the weight is at the top dead center position in rotation. Although the dynamics of the precise force applied is more complex due to any Coriolis acceleration or other dynamics caused by the deflection of the beam assembly in response to this oscillatory force which is relatively smaller when the rotating body is at top dead center as compared to when the rotating body is a bottom dead center.

[064] The resulting effect of this varying force is that the beam assembly oscillates in substantially vertical displacement as a result mostly of elastic deformation. This oscillatory movement is best timed to be at a frequency which is tuned to the natural frequency at which the beam assembly resonates. This can be affected by many different parameters including weight, weight displacement, weight distribution, structural parameters of the beam assembly, the mounting system used to support the beam assembly, the load and other factors which are known or hereafter recognized to provide resonant oscillation with the natural frequency to achieve more elastic storage of energy and greater efficiency.

[065] The deflection of the distal portions of the beam assembly produce deflection at the preferred location of the output 190 which may vary depending on magnitude of the driving forces which in the construction of Fig. 1 are oscillation forces. These oscillation forces and associated displacement are configured to apply output force on the output 190. Depending on the magnitude or resistance of the output the bending moments produced in the beam assembly will vary and may be of either positive or negative sense at the reaction point of the output connection and other positions along the beam assembly.

[066] The specific shape and construction of suitable rotating bodies which can be used in constructions according to the inventions hereof may vary considerably while being operable. - Magnet or Magnets

[067] Fig. 3 shows that the rotating body preferably has at least one magnet or more preferably multiple magnets 137, 138 and 139. In the preferred construction shown the magnets are permanent magnets and do not require any transmission of electrical current thereto. Alternatively, electromagnets may be used and a suitable sliding electrical connection may be possible but is not preferred in the embodiment of Fig. 1 and most others described herein.

[068] As indicated above the rotating body 131 is preferably driven by a driver which keeps the rotating body in orbit despite mechanical losses and the resistance provided by the rotational mounting and the output resistance.

[069] As shown, the driver is in the form of an electromagnetic pulse motor having electromagnets 141, 142 and 143. Electromagnets 141-143 are pulsed with electrical current in a suitable pattern found most advantageous to the particular dynamics of the system for which they are being used and economy of energy.

[070] The pulse motor driver 140 is controlled by controller 185 which advantageously senses the angular position of the rotating body using one or more detectors 186. At the desired times the controller 185 releases electrical charge pulses which generate magnetic fields using windings 145 about electromagnet cores 146 which intermittently pulses the magnet or magnets 137-139 on rotor 131. The pulsing, intermittent action of the electromagnetic pulse motor eliminates the need for continuous energy expenditure and thus can be tuned to the minimum amount needed to maintain rotation. The electromagnetic pulses are timed to optimally occur in conjunction with the magnet or magnets on the rotating body to provide torque thereto.

[071] This may be optimal by having each electromagnet pulse for each magnet on the rotating body to simultaneously fire. Another mode of operation may have the electromagnets of the drive fire sequential. Still another mode is to have the appropriate electromagnets fire sequentially and in each instance of where any rotor magnet is in position to have torque applied thereto. A further alternative is to have an optimization program which applies appropriate magnetic pulses as needed and are not continuous to potentially provide reduced maintenance. What will be optimal may vary from construction to construction and may benefit by using some of these techniques during a part of the cycle, such as at startup, during sustained periods, or upon shut down. Shut down may also provide an opportunity to back-feed electrical charge through the controller to the battery for storage.

[072] Fig. 1 also shows a battery 150 which acts as a store of energy, in the form of electro-chemical energy for controlled use by the pulse motor using controller 185 and electrical control 180 which controls the draw from the battery and charging thereof using a power source, such as electrical power source 160. As shown, the electrical power source may be photo-voltaic or other solar cells, or alternative sources of energy, such as from electrical mains, generators, wind electricity generators, or other suitable energy source which supplies usable power. The stored electrical energy of battery 150 for example can then be used to power the pulse apparatus or other device driving the rotating body.

SECOND EMBODIMENT

[073] A second embodiment is depicted in Fig. 4 with Fig. 5 showing in greater detail added features. The second embodiment has features which are numbered as in the first embodiment except the features of the second embodiment are in the 200 numeral range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above except the following differences.

- Beam Assembly Springs [074] Figs. 4 and 5 show another preferred alternative system 200. The system 200 indicates possible advantage to provide elastic energy storage in the form of one or more springs. As shown the springs are arranged with an upper spring 217 and a lower spring 218. As configured springs 217 and 218 are connected between the beam assembly 220 and the support 210. Alternative connection configurations are possible.

[075] Springs 217 and 218 may serve in either tension or compression whichever best serves operation of the oscillatory movement of the beam assembly 220.

[076] Such springs may alternatively be formed using other known spring configurations, such as air or other gas springs, wound springs, and many other possible types now known or hereafter developed and found suitable to facilitate operation or efficiency of system 200.

[077] System 200 also differs in that the power source 260 may be of various types of electrical power storage, such as provided by battery 250, or using other electrical energy storage subsystems, for instance capacitive or other suitable devices.

[078] An additional aspect of system 200 as shown is that it advantageously includes two position sensors 286 for providing added information for the control subsystem or subsystems being used.

THIRD EMBODIMENT

[079] A third embodiment is depicted in Fig. 6. The third embodiment has features which are numbered as in the first embodiment except the features of the third embodiment are in the 300 numerical range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above except the following differences.

- Dual Outputs [080] The system 300 is like system 100 except it has two outputs 390 which will have expected different displacements. Thus the outputs can be used to drive appropriate pieces or equipment or pieces of equipment best utilizing this configuration. One example may be a pump or compressor having two stages built to use either in parallel or more likely in sequence to achieve two-stage pressure increases. This may be utilized in a heat pump, air compressor, liquid pump, compressed gas motor or other applications using such outputs.

FOURTH EMBODIMENT

[081] A fourth embodiment system is diagrammatically depicted in Fig. 7. The fourth embodiment has features which are numbered as in the first embodiment except the features of the fourth embodiment are in the 400 numerical range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above except the following differences.

- Combined Support and Outputs

[082] Fig. 7 shows that system 400 uses two outputs 490 as the outputs and supports from the deflecting beam assembly 420. This configuration may be possible in some instances and be suitable or more suitable than other configurations taught herein.

[083] Fig. 7 shows a simply supported beam configuration wherein the oscillatory forces are distributed between the output/supports. As shown, this is advantageously done with the oscillatory force centered therebetween.

FIFTH EMBODIMENT

[084] A fifth embodiment system according to certain aspects of the inventions hereof is depicted in Fig. 8. The fifth embodiment has features which are numbered as in the first embodiment except the features of the fifth embodiment are in the 500 numerical range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above except the following differences.

- Support and Beam Connection

[085] Fig. 8 shows a dual cantilevered beam construction 520. The beam assemblies may be considered in parts 521 and 522. As shown the beams are advantageously arched or otherwise shaped in a curvilinear manner to reduce overall system height and to take advantage of any synergistic effects associated with having the beam assembly supported at the desired central position. Such construction advantageously has two rotating bodies 530.

- Deflecting Members

[086] Fig. 8 shows an embodiment in which the deflecting members have a generally bow- shaped construction which may be easier to tune to a desired natural resonance frequency. The deflecting members may have other possible shapes and constructions as well. Each separate construction may be adapted to make the apparatus more efficient depending on the specific construction of the accompanying parts.

- Connection of Deflecting Members

[087] In Fig. 8 the deflecting members 521 and 522 are advantageously mounted upon the sides of the support 520. The positioning of the right and left portions 52 land 522 of the deflecting members may be adjusted by an adjustment such as in the form of a tuning piece. A tuning piece is advantageously in the form such as a movable bolt or other part which engages the central part of the beam assemblies using a mount 512. The bolt can be engaged in varying degrees and at an adjustable position to balance the resonant frequencies of the two different sides and to otherwise affect oscillatory action or dynamic response of the beam assemblies. This may facilitate adjustment of the natural frequencies and thus allow the two beam subassemblies to achieve matching resonance. Such coordinated natural resonance may provide elastic dynamic response characteristics for the deflecting members which is advantageous in some manner either operationally or from an efficiency standpoint.

[088] As shown in Fig. 8, the connection includes a connection or mounting piece 512 which is screwed or otherwise mounted to the support. The dampening of the connection can be varied by the coordination or dis-coordination of the mounting cap and the shape of the adjacent beam assembly part received therein. Such may also be affected by using springs as indicated above or by using an enclosed elastic ferrule to achieve the desired resonant frequencies and cooperating degree of dampening, if any dampening is found desirable for some benefit.

[089] The deflecting members can also be connected in any other alternative way such as described above and other suitable alternatives now known or discovered of developed hereafter.

- Rotating Bodies

[090] As depicted in Fig. 8, there may be more than one matching eccentrically loaded rotating body or rotor 530. In the case that there are more than one, the eccentrically loaded rotating bodies may be advantageously built substantially similar in structure. Each additional rotating body is mounted on deflecting members 520. These may or may not be equidistant from the connection with the support depending on the loads applied by outputs 591 and 592.

[091] Each rotating body 531 and 532 may have its own separate pulse motor which may or may not run from the same input and operate as the same frequency and develop the same forces. Operation out of phase may be found superior in some cases, or other operational regimes may be found most preferred for different applications and installations having different loads. As shown, the outputs 591 and 592 drive compressors 593 and 594. SIXTH EMBODIMENT

[092] A sixth embodiment system 600 is depicted in Fig. 9. The sixth embodiment has features which are numbered as in the first embodiment except the features of the sixth embodiment are in the 600 numerical range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above embodiments except the following differences.

- Drive Assemblies

[093] System 600 advantageously uses a cantilevered construction similar to that depicted in Fig. 8. However system 600 has dual drivers associated with each rotating body. The upper drivers 641 and lower drivers 642 have control systems and position sensors (not shown) analogous to those shown for system 100 but adjusted or added to in order to provide pulsed driving of the rotating body 630 at more than one position about the angular displacement range of the rotating body.

[094] The system configuration may be preferred in certain installations. One possible advantage may be that the system 600 can be started after the imbalanced rotors are de-energized and left to swing into a downward position. Automatic restart would be facilitated by the lower drives 642 which may apply torque in as many passages as needed to achieve full rotation. This may involve pendulum action until the rotors have achieved positions where the upper drivers can apply torque and using controllers and position sensors to determine the direction of rotation implemented by the control system.

[095] During operation the rotors may operate in phase, out of phase or in another relationship which facilitates the use of the outputs to drive pumps, compressors or other inner equipment 691 and outer equipment 692 connected to the oscillating beam assemblies 620 which have first sides 621 and second sides 622. [096] It is also possible that only upper drivers 641 may be needed once operation has reached the desired angular velocity to potentially reduce the amount of energy consumed in maintaining operation.

- Dual Outputs Along Each Side

[097] Another possible advantage of system 600 is that torque may be applied to the rotors 630 at both the top and bottom or other suitable positions to help drive the added load of dual outputs 690 which are connected to the beam assemblies extending in each direction from the support 610. The upper and lower drives may also be used to adjust the angular velocity in a more controlled manner than provided merely by gravitational force converted into angular momentum under the first embodiment and others which may be constructed by the systems and apparatuses according to the inventions hereof.

SEVENTH EMBODIMENT

[098] A seventh embodiment system 700 is depicted in Figs. 10 and 11. The seventh embodiment has features which are numbered as in the first embodiment except the features of the seventh embodiment are in the 700 numerical range instead of in the 100 numerical range. Otherwise the construction is adequately described by the above descriptions except the following differences.

- Support, Beams and Beam Couplings

[099] Support 710 is constructed differently and has two uprights 711 and 712 which support a horizontal support member 713 to which the beam assemblies are mounted upon an upper surface thereof.

[0100] The horizontal support member 713 has three beam mounting couplings 718 which are used to connect three parallel beams 721, 722 and 723 into beam assemblies 720 extending in each direction to form two beam assemblies 726 and 727 which are at the first or left side and the second or right side as pictured in Figs. 10 and 11. The two beam assembly parts 726 and 727 extend from the centrally located support member 710.

[0101] In the configuration shown in Figs 10 and 11 the distal ends of the beams are connected by transverse beam end pieces 724 and 725. Thus the beam assemblies 726 and 727 preferably operate in unison. However, the opposing beam assemblies may be in phase, out of phase or in a more complex deflection relationship if found desirable.

- Rotating Bodies

[0102] Figs. 10 and 11 show dual rotors 731 and 732 at the first side mounted upon the first beam assembly 726 and dual rotors 733 and 734 at the second side mounted upon the second beam assembly 727. As shown the rotors are formed as wheels.

[0103] Each rotor may have one or more diametric members 731 which allow them to be supported upon first and second shafts 728 and 729 at the first and second beam ends 726 and 727. Due to the connected nature of the beam assembly ends using the end pieces 724 and 725, the rotors turn in unison at each end.

[0104] The rotors can be provided with opposing mounting sections 735 and 736 which are preferably used to provide added strength where the diametrical spoke or arms 731 connect thereto. The weight of the mounting sections is preferably different so that the imbalance causes the oscillatory forces to be developed to deflect the beam assemblies at their natural frequencies.

[0105] Due to the inclusion of the opposed mounting sections 735 and 736 the weights of each may be adjustable to achieve varying frequencies which in some cases may make it easier to tune the system to provide uniform deflection even though the rotors and beams are ganged together. Depending on the angular velocity and weight imbalance it may be possible to achieve lower or higher frequencies by adjusting the imbalance.

- Power Source

[0106] In this embodiment the upper and lower drivers associated with each rotor may be electromagnetic as shown above or use another form of applying torque without contact. For example air jets 749 could be used if the outputs 790 are connected to compressors 791 and a tank (not illustrated) to store energy in the form of compressed air which maintains energy capacity without losses better than batteries in many instances, particularly over long periods of inactivity.

[0107] Alternatively, the drivers may be a combination of electromagnetic and air pulsations if quicker startup is desired and storage of energy is desired in more than one type of energy storage form. This arrangement may allow air jetting at startup coupled with operation of upper and lower electromagnetic drives during further speed increase and then return to simply electromagnetic drive by the top drivers as in other embodiments described above.

POWER AND ENERGY RECOVERY

[0108] Fig. 12 shows a system 800 similar to system 600 of Fig. 9. The reference numbers used in Fig. 12 are similar to those in Fig. 9 with the exception that the leading digit is changed from "6" to "8". Other more specific reference numbers may be used below.

[0109] System 800 includes an optional secondary power recovery subsystem and a secondary energy storage subsystem which may advantageously be used in some preferred embodiments according to the invention. In a preferred version illustrated in Figs. 12-16, the secondary energy storage is embodied as a suitable secondary energy storage device 880 such as recovery cells, which may include battery cells. Other electrical energy storage devices such as capacitors may be used to store energy. Still further, the secondary energy storage may further include additional storage means for storing energy which might be employed in some systems if desired or justified. Secondary power recovery subsystem may include any combination of the recovery controller 898, supply controller 899, and circuitry 901 to direct power to primary supply cells 850 and/or secondary energy storage devices 880. More particularly, the recovery controller 898 and the supply controller 899 may be coupled together and/or to primary energy storage devices 850 and/or to secondary energy storage devices 880 to couple any given number of energy storage cells in series and/or in parallel with the recovery controller 898 or the supply controller 899 so that any of the energy storage devices may operate as supply or recovery cells. The power directed by the secondary power recovery subsystem may be generated when the permanent magnets of the rotor 830 pass by electromagnets or the power may be drawn from electromagnets during a powering down cycle as will be described in further detail below.

- Secondary Energy Storage

[0110] The secondary energy storage portion is powered by a preferred secondary power recovery subsystem 900, shown in greater detail in FIG. 13 A. The preferred secondary power recovery subsystem as shown uses part of, or all of, the energy stored in an induced electrical field in the inductor of one or more of the electromagnets, which otherwise would be dissipated and lost. Instead, this stored energy in the induction coils of the electromagnet is utilized to energize the secondary energy storage device or devices 880. Additionally or alternatively, the energy may be electronically directed to electromagnets 889 and/or electromagnets 845 to reduce the source input voltage necessary to move the rotor 830 and operate the pump/motors 890. While, for the sake of simplicity, electromagnets 845 are not illustrated in Fig. 12 as coupled to the secondary power recovery subsystem, one skilled in the art would recognize that these elements may be coupled together using conventional techniques.

[0111] As shown, the secondary energy storage devices may include recovery cells such as batteries, which may be of any suitable type. For example, battery types such as nickel cadmium, lithium ion, lead acid, solid state, and so forth may be used. Additionally or alternatively, capacitive storage devices may be used, such as ultra capacitors, super capacitors or other capacitive storage devices. These energy storage devices are also generally referred to herein as recovery cells 880 and/or recovery cells 916 and such numerals may be used interchangeably. Other suitable storage devices may also be incorporated as will be appreciated by those skilled in the art.

- Primary Power Supply for Torque

[0112] Fig. 12 shows a system in which, according to one embodiment, the upper or primary electromagnets 845 may be the primary or sole torque -inducing component of the system 800 for rotating the rotor assemblies 830. Alternatively, any electromagnets may be placed in the stator orbit and energized to develop torque upon the rotor at controlled times such as may be advantageous particularly during startup. Additional electromagnets 889 may be mounted in the stator orbit at any location as "pick-up coils" to take advantage of the changing magnetic fields produced by the forces inherent in the motion of the eccentric magnetically loaded rotor 830 past the electromagnet 889 (or electromagnet 845). Thus, any of the electromagnets (e.g. 845 or 889) may be configured in a driving mode, for driving a rotor assembly 830, or a pick-up mode, for utilizing the changing magnetic fields produced by the forces inherent in the motion of the eccentric magnetically loaded rotor 830. Moreover, any of the electromagnets may be converted to switch between the driving mode and the pick-up mode. [0113] According to one implementation, the lower positioned electromagnets 889 may be used in a convertible fashion, switching between a first mode and a second mode. In the first mode, the electromagnets 889 are used for power recovery, converting the magnetic field created between the permanent magnets passing by the electromagnets 889 to generate an electric signal. In the second mode, the electromagnets 889 assist in actively affecting the motion of the rotor. In this second mode, the electromagnets 889 may be activated to assist in moving the rotor 830 during startup or to add additional torque to the rotor using an applied electromagnetic field/force once the rotor 830 is in motion. It is noted that while electromagnets 889 are shown on a lower portion of the system 800, they may be placed anywhere around the orbit of rotors 830 as desired or required for a given application.

[0114] According to one preferred arrangement, the eccentric permanent magnet rotor 830 is balanced for maximum efficiency to transform the momentum, centrifugal force, electromagnetic force, and other forces that occur during rotation to keep the rotor in motion at any desired speed for a desired pump output from pumps 891 or 892. The electromagnets may convertibly take advantage of the changing magnetic field as previously described. The optimum weight distribution of the rotor is tuned for maximum efficiency depending on the desired pump output characteristics, while the supply controller 899 is configured to direct power to one or more electromagnets to maximize storage efficiency and minimize energy consumption of the system.

- Control of Recovery Power

[0115] The recovery or secondary power system controller 898 is used to help control operation of the recovery power, and storage within, the recovery energy storage devices 880. Additionally or alternatively, the secondary power system controller 898 may enable energy from the storage devices 880 to be used by the supply controller 899 or by the system 800 generally. Thus, the secondary power system controller 898 may be configured to direct voltage or current to, or from, the energy storage devices 880 to the primary or supply controller 899 to utilize the recovered electrical energy directly. In general, if the potential developed in the energy storage cells 880, for any cell or combination of cells in series or parallel, becomes greater than the potential (e.g., voltage) in the primary supply cells 850 then the voltage or current can be directed for immediate use in the system 800 or to source storage cells 850 for later use in the system 800. This is advantageously controlled so that a potential difference in supply cells 850 and recovery cells 880 is maintained to keep the rotor 830 in motion to optimize efficiency over varying output load demands. This potential difference from the main supply to the recovery supply typically occurs when elevated voltages exist in the secondary storage devices 880 (i.e. recovery supply) versus the primary storage or source input (i.e. main supply). Maintaining the voltages at a balance assists in making the system run smoothly and efficiently.

[0116] Once the rotor 830 is in motion, the rotor position is detected by proximity sensors which, as shown in Fig. 12, may be in the form of Hall sensors 886. Information may be provided to the recovery controller 898 via a conventional circuit (not illustrated for the sake of simplicity and clarity in the figures) to optimize the sensing and triggering of the electromagnets 845 and/or 889. Any emf generated by the system 800 may be transferred as current through electromagnets 889. The current is then communicated to circuitry 901, via wiring 842, to the recovery controller 898 and, ultimately, the energy storage devices 880.

[0117] Sensors 886, such as Hall sensors, are shown in the lower portion of system 800, however, it is understood that the sensors may be placed in any suitable location that allows the position of the rotor 830 to be determined. Furthermore, a magnet may be provided 180° from the any portion of the rotor 830, such as by an arm that extends in an opposite direction from the rotor arm in the example shown in Fig. 12 to be detected by the sensor 886. In such an instance, if the sensor 886 is implemented as a Hall sensor, it may detect the presence of the magnet. This information may indicate that the position of the rotor as 180 0 away from the Hall sensor 886 in the rotational cycle. Sensing the position may trigger the supply controller 899 to provide a pulse of current to one or more of electromagnets 845, 888, and/or 889. One skilled in the art will appreciate that the sensor 886 may be configured in any known manner, such as an optical sensor, electrical sensor, or any other conventional sensor located at any suitable point of the rotor 830 or elsewhere in the system 800 for determining where the permanent magnets of the rotor 830 are located relative to electromagnets 845, 888, and/or 889 within the rotational path.

[0118] Fig. 13A diagrammatically shows features of the secondary energy storage subsystem and the secondary power recovery subsystem referred to with regard to Fig. 12. As set forth previously, the circuitry 901 may be coupled to the electromagnets 845, electromagnets 889, or both. The upper electromagnets 845 may be additionally or alternatively connected as described herein above for other versions and, as such, need not be repeated to understand the implementations shown in Figs. 12-14.

[0119] In Fig. 13A, the primary cells 850 (originally shown in Fig. 12), which provide electrical energy through primary or supply controller 899 (originally shown in Fig. 12), may be collectively referred to as power source 902. The power source 902 drives current through electromagnets, shown schematically as inductor coil 904. When the circuit is in a first mode, the current passes to ground 906, which may be common to ground 908, as illustrated by dotted line 909. The current may pass across transistor 912 due to a signal being sent from the sensor 886 to the base or control terminal of the transistor 912 to "close" (or turn "on") the transistors, i.e. allow conduction from the emitters to the collectors and thus act as a path to ground to help dissipate excess induced current and pass it to ground 906. When the sensors 886 (e.g. Hall sensors) detect that the rotor 830 is in a position such that one or more of the permanent magnets on the rotor are moving away from one or more of the electromagnets 845, a signal sent from the sensor 886 to the base or control terminal of the transistor 912 is altered to "open" (or turn "off) the transistors, i.e. prevent conduction from the emitters to the collectors and thus direct current through diode 914. The remaining recovery current is directed from coils of the electromagnets 904 through a diode 914 to power recovery cells 916, which may correspond to the energy storage devices 880 shown in FIG. 12.

[0120] The recovery current from the electromagnet 904 may be directed via the recovery controller 898, shown in FIG. 12, but not shown in FIG. 13A for the sake of convenience. The recovery controller 898 may additionally or alternatively control the output path from the recovery cells 916 (where recovery cells 916 may include supply cells 850 and/or recovery cells 880) to direct power to other portions of system 800. For example, the recovery cells 916 may provide supplemental or replacement voltage to the electromagnets 904. Additionally or alternatively, the recovery cells 916 may power opto-isolators or other desired component.

[0121] Since the supply voltage used to drive the electromagnet 904 is relatively high, the sensor 886 preferably includes one or more opto-isolators (not shown) between the sensor(s) 886 and the transistor 912. The opto-isolators may isolate high voltage and low voltage electronics . As mentioned above, the sensor(s) 886 may be powered by the recovery cells 916, though the electrical path between these components is not shown for the sake of simplicity.

[0122] Other configurations may be used to supply current to recovery cells 916. For example, as shown in Fig. 13B, circuitry 900' similar to circuitry 900 may be used in which the transistor 912, power supply 902, and Hall sensor circuitry 910 are removed, disabled, or otherwise not active in the circuitry 900'. Such a circuit 900' may be used in the case of electromagnets that are configured in the pickup mode as opposed to the driving mode or convertible configuration. The pick-up coils of the electromagnet 904' produce a changing emf field on both sides of the electromagnet 904' as the permanent magnet of the rotor 830 approaches the collector coils and as it accelerates past. This generates a signal at the electromagnet 904' which may be used in circuit 900'. Thus, the circuit 900' in this passive state does not require the sensor 886, power supply 902, or transistor 912. Moreover, a secondary recovery cell 917 coupled to a diode 913 may be utilized such that charge is collected both when the permanent magnet is moved toward and away from the electromagnet 903', thus generating two voltage spikes of opposite polarities and possibly differing magnitudes.

[0123] Fig. 14 depicts recovery circuitry 1000, which may augment, supplement, be used in place of circuitry 900. The circuitry 1000 may be coupled to electromagnets 845, electromagnets 889, or both. The upper electromagnets 845 may also be connected as described herein above for other versions and, as such, need not be repeated to understand the implementations shown in Figs. 12-16. Electromagnets 845 and/or electromagnets 888/889 may additionally or alternatively be provided anywhere along the rotational path of rotor 830 as shown in Fig. 12 and are represented in Fig. 14 by inductor coils 1003, 1004, and 1005.

[0124] In Fig. 14, the primary cells 850 (originally shown in Fig. 12), which provide electrical energy through primary or supply controller 899 (originally shown in Fig. 12), are collectively referred to as power source 1002. The power source 1002 drives current "I" through the circuit as demonstrated by the arrows associated with the "I"s. When the circuit is in a first mode, the current passes to ground 1006, which may be common to ground 1008, as illustrated by dotted line 1009. The current may pass across transistor 1012 due to a signal being sent from the sensor 886 to the base or control terminal of the transistor 1012 to "close" (or turn "on") the transistors, i.e. allow conduction from the emitters to the collectors and thus act as a path to ground to help dissipate excess current and pass it to ground 1006. The majority of the current in the circuit is directed to the transistor 1012 since it is positioned in a direct path to ground when conducting and current directs to the shortest path to ground.

[0125] Fig. 15 shows the same circuit as Fig. 14, but with the transistor 1012 in an "open" or "off position. This state may occur when the sensors 886 detect that the rotor 830 is in a position such that one or more of the permanent magnets on the rotor are moving away from one or more of the electromagnets 845 or that the electromagnets 845 no longer need to provide a torque to the rotor 830. In this mode, current is not drawn from the power source 1002. However, each electromagnet 1003, 1004, and 1005 will have residual recovery current "I" stored therein. This remaining recovery current is directed from the electromagnets 1003, 1004 and 1005 to power recovery cells 1016 and 1017. Recovery cell 1016 is charged, via diode 1014, from the residual current in electromagnets 1004 and 1005. Recovery cell 1017 is charged from the residual recovery current in electromagnet 1003, which may at least in part be derived from the residual current in electromagnets 1004 and 1005 gathered when the transistor 1012 was "on" or "closed." The current from the electromagnet 1003 flows into the positive terminal of the recovery cell 1017. In an exemplary operation, the transistor 1012 may be "on" for 5 ms and "off for 10 ms, though other times and cycles may be selected to optimize performance.

[0126] Fig. 16 illustrates an alternative recovery circuit for circuitry 900. Power supply 850 provides a current to electromagnets 889. When then sensors 886 place the bipolar transistors 930 in an "on" state, current is drawn from the power supply 850 through the electromagnets 889 to ground 950. When the sensors 886 place the bipolar transistors 930 in an "off state, the residual current within the circuit and within the electromagnets 889 is drawn through diodes 960 to charge recovery cells 880. The recovery cells 880 may then provide power back into circuitry 900, to sensors 886 or for any other suitable purpose.
