DETAILED DESCRIPTION OF THE EMBODIMENTS FIG. 1 shows a sectional elevation view of an electric device 10, while FIG. 2 shows a perspective view of electric device 10. In one or more embodiments, electric device 10 is an electrical alternator while in other embodiments, electric device 10 is an electrical motor. For ease of description, electric device 10 will be described as a linear electric alternator to generate an electric output based on rotation of a driveshaft 12 by an outside source, however, it will be appreciated that electric device 10 may alternatively be provided with an electric input in order to drive driveshaft 12 as an electric motor. In any event, a driveshaft 12 extends along a driveshaft axis 14 and passes axially through the center of the linear electric alternator assembly 10. Driveshaft 12 is supported by a pair of bearings 16a, 16b in a fixed axial position. Positioned along driveshaft 12 is at least one harmonic cam 18 with a cam radius R _c . In one or more embodiments, positioned along driveshaft 12 in spaced apart relationship to one another are two harmonic cams 18a, 18b. Positioned radially outward from driveshaft 12 is at least one power generation assembly 20, which power generation assembly 20 may generally be positioned adjacent the outer periphery of a cam 18 at approximately the cam radius Rc. Each power generation assembly 20 has a magnet assembly 22 and a coil assembly 21 axially aligned with one another along a coil assembly axis 25, wherein at least a portion of the magnet assembly 22 is reciprocatingly disposed within a stator cylinder assembly 24 of the coil assembly 21. In one or more embodiments, such as in the illustrated embodiment, a portion of each of a first magnet assembly 22a and second magnet assembly 22b may be reciprocatingly disposed within coil assembly 21 along coil assembly axis 25. In one or more embodiments, such as in the illustrated embodiment, two power generation assemblies 20a, 20b are provided, each power generation assembly 20 having first and second magnet assemblies 22a, 22b. Each coil assembly 21 is defined along coil assembly axis 25 and includes a stator cylinder assembly 24 having a stator cylinder 60 along which is radially disposed at least one electromagnetic windings or coil 68. Windings 68 may connect to an electrical terminal 27 from which one or more leads 29 extend. Coil assembly axis 25 is spaced apart from but generally parallel with driveshaft axis 14 of driveshaft 12. Each magnet assembly 22 generally includes a cam follower assembly 26 attached to a magnet slide arm 28, which may be any reciprocatable member, such as a magnet slide or yolk, to which is mounted a magnet 30. In one or more embodiments, magnet 30 is one or more permanent magnets. In such embodiments, magnet 30 may be a plurality of discreet permanent magnets arranged to have alternating polarities. In other embodiments, magnet 30 may be an electromagnet formed of energizable electromagnetic windings or coil. In embodiments with first and second magnet assemblies 22a, 22b, the respective magnet slide arms 28a, 28b oppose one another in coil assembly 21 and are adapted in some embodiments to reciprocate along coil assembly axis 25, thereby causing the magnet 30 to induce a flow of electric current in windings 68. Each cam follower assembly 26 engages a corresponding cam 18 and acts on its associated magnet slide arm 28. A magnet slide chamber 32 is generally defined within coil assembly 21 and disposed to receive at least a portion of magnet slide arms 28a, 28b. Depending on the particular power output requirements of linear electric device 10, in some embodiments, movement of opposed magnet slide arms 28a, 28b may mirror one another, moving away from or towards each other during a stroke, while in other embodiments, movement of opposed magnet slide arms 28a, 28b may follow one another, moving in the same direction along coil assembly axis 25 during a stroke. In other embodiments, only a single cam 18 may be provided on driveshaft 12 and only a single magnet assembly 22 may be disposed within a coil assembly 21. In one or more embodiments, linear electric device 10 includes at least two power generation assemblies 20 symmetrically spaced about driveshaft axis 14. In the illustrated embodiment, a first power generation assembly 20a and a second power generation assembly 20b are shown, each having a magnet assembly 22 and a coil assembly 21. In other embodiments, three or more power generation assemblies 20, each with a corresponding magnet assembly 22 and coil assembly 21, may be symmetrically spaced about driveshaft axis 14. Each coil assembly 21 may have either one or two magnet assemblies 22 disposed for reciprocating movement within the coil assembly 21. Where linear electric device 10 is an alternator, as will be explained in more detail below, as driveshaft 12 is rotated by an external source (not shown), such as from an internal combustion electric alternator, wind turbine, water turbine or other rotary equipment, cam 18 is likewise rotated. As cam 18 rotates, the harmonic or undulating shape of cam 18 forces each cam follower assembly 26 engaging cam 18 to have a back and forth, linear movement. Moreover, because each cam follower assembly 26 is constrained within a stator cylinder 24, the linear movement is along coil assembly axis 25 within coil assembly 21. As such, rotational movement of cam 18 results in linear movement of cam follower assembly 26. Since cams 18 are fixedly mounted on driveshaft 12, cam 18 is rotated through an angle by driveshaft 12. The harmonic or undulating shape of cam 18, therefore determines the stroke of each magnet assembly 22, and in particular, the linear movement of magnet slide arm 28, within a stator cylinder 24 of coil assembly 21. In one or more embodiments, a first flange 44 is attached to a first end 46 of driveshaft 12 and a second flange 48 is attached to a second end 50 of driveshaft 12. As shown, a flywheel 52 may be mounted on first flange 44. The power generation assemblies 20 are mounted in a housing or enclosure 53. A sump casing 54 may be attached to the enclosure 53 adjacent the first end 46 of driveshaft 12 and a sump casing 56 may be attached to enclosure 53 adjacent the second end 50 of driveshaft 12. FIG.3a illustrates one embodiment of a coil assembly 21 disposed along a coil assembly axis 25. Specifically, coil assembly 21 has a stator cylinder assembly 24 formed of a stator cylinder 60 extending between a first end 62 and a second end 64 and generally formed of a cylinder wall 66. A first set of electromagnetic windings 68 is disposed along cylinder wall 66 between the first and second ends 62, 64. In one or more embodiments, the windings 68 may be one or more electric coils. In one or more embodiments, a second set of windings 70 may likewise be disposed along cylinder wall 66. In some embodiments, second set of windings 70 may be spaced apart from first set of windings 68, while in other embodiments, windings 68, 70 may abut one another. Although not necessary, in one or more embodiments, windings 68 extend around the full perimeter of cylinder wall 66. Windings 68 as described herein are not intended to be limited to a particular shape or configuration along cylinder wall 66, but may take any form known in the prior art and may generally include, but are not limited to, one or more wires which form loops perpendicular to coil assembly axis 25, parallel to coil assembly axis 25 or angled relative to coil assembly axis 25. In this regard, the coil density the first set of electromagnetic windings 68 may be the same as or different than the coil density the second set of electromagnetic windings 70. For example, the first set of electromagnetic windings 68 may have a first coil density and the second set of electromagnetic windings 70 may have a second coil density different than the first coil density. Windings 68 may connect to an electrical terminal 27 from which one or more leads 29 extend. Thus, where the electric device 10 is a linear electric alternator, persons of skill in the art will appreciate that leads 29 may be used to deliver an electrical output from windings 68, whereas, where the electric device 10 is an electric motor, persons of skill in the art will appreciate that leads 29 may be used to deliver an electrical input to windings 68, as described below. In one or more embodiments, windings 68 have an outer winding edge 61 closest to the first end 62 and an inner winding edge 63 closest to second end 64. Similarly, windings 70 have an outer winding edge 65 closest to the second end 64 and an inner winding edge 67 closest to first end 62. Inner dead center (IDC) of the stator cylinder 60 is defined approximately equidistance between the outer edge 61 of windings 68 and the outer edge 65 of windings 70. In one or more embodiments, the inner winding edge 67 of windings 70 is closer to IDC than the inner winding edge 63 of windings, while the outer winding edge 65 of windings 70 is approximately the same distance from IDC as the outer winding edge 61 of windings 68. Moreover, outer dead center (ODC) of the stator cylinder 60 is defined approximately at the outer edges 61, 65 of the respective windings 68, 70. Magnet slide chamber 23 is defined within stator cylinder 60 between the outer edges 61, 65, and thus represents the portion of stator cylinder 60 where current is generated by movement of a magnet slide arm 28 therein. FIG. 3b illustrates another embodiment of a coil assembly 21, where only a single set of windings 68 is carried by stator cylinder 60. Specifically, coil assembly 21 has a stator cylinder assembly 24 formed of a stator cylinder 60 extending between a first end 62 and a second end 64 and generally formed of a cylinder wall 66. Windings 68 are disposed along at least a portion of cylinder wall 66 between the first and second ends 62, 64. Windings 68 have a first outer winding edge 61 closest to the first end 62 and a second winding edge 63 closest to second end 64. IDC of the stator cylinder 60 of FIG.3b is defined approximately equidistance between the outer edges 6163 of windings 68. ODC of the stator cylinder 60 of FIG. 3b is defined approximately at the outer edges 61, 63 of windings 68. Windings 68 is shown as having leads 29 for electrical connection thereto. Coil assembly 21 may also be characterized as having a particular coil density of electromagnetic windings 68. It will be appreciated that in or more embodiments, where multiple coil assemblies 21 may be present in an electric device 10, the coil densities of the coil assemblies 21 may differ in order to permit greater output options for electric device 10, as described in more detail below. One benefit to the above described electric device 10 is because of the manner in which forces are transferred from the driveshaft 12, to the cam 18 to the cam follower assembly 26, the forces are balanced with little torque placed on the components. For these reasons, lower strength, lower temperature materials may be used to manufacture certain components of electric device 10. Such materials may include plastics, ceramics, glass, composites or lighter metals, which also have the added benefit of reducing the overall weight of the electric device of the disclosure. Turning to FIG. 4A, an exploded side view of a magnet assembly 22 is illustrated. Magnet assembly 22 generally includes a magnet slide arm 28 to which is mounted a magnet 30. Magnet assembly 22 is attached to a cam follower assembly 26 attached, all generally aligned along axis 71. Cam follower assembly 26 is an elongated structure 72 having a first end 74 and a second end 76. A notch or opening 84 in structure 72 is formed between ends 74, 76, which notch or opening 84, as described herein, is disposed for receipt of a cam 18 and in particular, a cam shoulder 138 (see FIG. 5a). Each end 74, 76 may be a cylinder which ends 74, 76 may be interconnected by a cam follower arm 78. In some embodiments, cylindrical end 74 may be of a larger diameter than cylindrical end 76, while in other embodiments, cylinder ends 74, 76 may be of the same diameter. Cam follower arm 78 may be rigidly attached to each cylindrical end 74, 76, or pivotally attached to one or both cylindrical ends 74, 76. In this regard, elongated structure 72 may be a unitary body or may be formed of interconnected components, such as cylindrical ends 74, 76 interconnected by cam follower arm 78. In one or more embodiments, cam follower arm 78 is pivotally attached to cylindrical end 74 and rigidly fixed to cylindrical end 76. In one embodiment, cam follower arm 78 is pivotally attached to cylindrical first end 74 and pivotally attached to cylindrical second end 76, permitting at least one degree of freedom therebetween. In one or more embodiments, an axially extending slot 80 may be formed in first end 74 and an additional axially extending slot 82 may be formed in second end 76. First and second cylindrical ends 74, 76 may be interconnected by cam follower arm 78 so that slots 80, 82 are oriented to extend along planes that are generally parallel to one another. Cylindrical ends 74, 76 are spaced apart from one another by cam follower arm 78 to form opening 84 between slots 80, 82. In any event, cam follower assembly 26 may include at least one engagement mechanism 86 carried by the first end 74 and adjacent opening 84. In one or more embodiments, cam follower assembly 26 may include a first engagement mechanism 86 carried by the first end 74 and adjacent opening 84 and a second engagement mechanism 88 carried by the second end 76 and adjacent opening 84 so that the first and second engagement mechanisms 86, 88 oppose one another. Engagement mechanisms 86, 88 may be mounted on their respective ends 74, 76 so as to extend into opening 84. The opposing engagement mechanisms 86, 88 are disposed to clamp, bear against or otherwise engage the harmonic surface of cam 18. In one embodiments, engagement mechanisms 86, 88 may be rollers that are mounted in above described slots 80, 82 and at least partially extend into opening 84. Thus, in FIG. 4a, a first roller 86 is mounted in first slot 80, and a second roller 88 is mounted in second slot 82. Preferably, each roller has a rotational axis that is generally parallel with the rotational axis of the other roller and which axii are generally perpendicular to the planes along which the slots 80, 82 are formed. In one embodiment, roller 86 is of a larger diameter than roller 88 because roller 86 is utilized primarily to transfer the load to magnet slide. An adjustable spacer 90 may be mounted on arm 78 between rollers 86, 88 and opening 84. Spacer 90 is adjustable to move radially relative to combined assembly axis 71, towards or away from opening 84 in order to align cam follower assembly 26 with a cam 18. In one embodiment, adjustable spacer 90 may be a pad that bears against outer surface 145. An internal lubrication passage 92 may be defined and extend within arm 78. Lubrication passage 92 is in fluid communication with a port 94 opening adjacent roller 86 so as to lubricate the bearings 87 of roller 86; a port 96 opening adjacent roller 88 so as to lubricate the bearings 89 of roller 88; and a port 98 disposed along the outer surface 100 of arm 78. Cylindrically shaped second end 76 of cam follower assembly 26 may have a bore 102 formed therein, and may have one or more windows 103 opening into bore 102. While the engagement mechanisms 86, 88 of cam follower assembly 26 have generally been described as rollers in some embodiments, it will be appreciated that the engagement mechanisms 86, 88 of cam follower assembly 26 can be any structure that is disposed to bear against, ride along or otherwise engaged one or more surfaces of harmonic cam 18. For example, rollers 86, 88 and slots 80, 82 may be replaced with opposing pads (not shown) that clasp opposite surface of cam 18. In this regard, elongated structure 72 of cam follower assembly 26 may simply be an elogated body having a first end 74 and a second end 76 with a radially extending notch or opening 84 formed in elongated structure 72 between the two ends but without the additional slots 80, 82. In this embodiment, one or more engagement mechanisms 86, 88 may be mounted in the radially extending notch 84 to engage a cam 18. Magnet slide arm 28 is attached to cam follower assembly 26 at the first end 74 of structure 72. Disposed on magnet slide arm 28 is a magnet 30. In one or more embodiments, magnet 30 is a permanent magnet. In other embodiments, magnet 30 may be electromagnetic windings or coil. Although not limited to a particular shape, in one or more embodiments, magnet slide arm 28 is a central rod or shaft 104 on which magnet 30 is mounted. In one or more embodiments, magnet slide arm 28 may be formed of a first annular guide body 110 spaced apart from a second annular guide body 112 of similar diameters and interconnected by shaft 104. Shaft 104 may be solid or have a bore formed therein, but is of a smaller diameter than annular guide bodies 110, 112 so as to form an annulus 116 between the spaced apart annular guide bodies 110, 112. At least one, and preferably two or more, annular grooves 118 may be formed around first annular guide body 110 for receipt of a seal ring (not shown). Likewise, at least one, and preferably two or more, annular grooves 120 may be formed around second annular guide body 112 for receipt of a seal ring (not shown). Although two annular guide bodies are not necessary, in some embodiments, magnet slide arm 28 utilizes two annular guide bodies 110, 112 spaced apart from one another along shaft 104 in order to ensure proper alignment of magnet 30 as magnet slide arm 28 reciprocates within stator cylinder assembly 24 (see Figs.1 and 2) as described herein. In one or more embodiments, magnet 30 may include a plurality of discrete permanent magnets 34 generally axially adjacent one another on shaft 104, each adjacent discrete permanent magnet 34 having axially opposed polarities or poles (not shown). In one or more embodiments, the plurality of discrete permanent magnets 34 may be arranged in an alternating magnetic configuration so that adjacent discrete magnets 34 face one another with the opposite magnetic polarity. The discrete magnets 34 may be mounted on shaft 104 and held in position by annular guide bodies 110, 112, or as shown, in between first and second retainers 36, 37, respectively. Retainers 36, 37 may be lock washers, retaining rings, bolts, fasteners or any other mechanism that can be utilized to promote radial orientation f a magnetic field (not shown) of the discrete magnets 34 forming magnet 30, i.e., substantially perpendicular to the stator cylinder assembly 24 (see Figs.1 and 2) for increased efficiency of linear electric device 10. In one or more embodiments, magnet 30 may extend fully within annulus 116 between first and second annular guide bodies 110, 112 and be secured on shaft 104 by first and second annular guide bodies 110, 112. With reference to FIG. 5a, harmonic cams 18a, 18b are shown in more detail mounted on driveshaft 12. As described above, driveshaft 12 extends along a driveshaft axis 14 between a driveshaft first end 46 and a driveshaft second end 50. Barrel cams 18a, 18b are mounted along driveshaft 12 in spaced apart relation to one another. Each cam 18 includes a cam hub 136 formed about a hub axis which cam hub 136 is mounted on driveshaft 12 to be coaxial therewith. Each cam 18 further includes a circumferential cam shoulder, disk or plate 138 extending around the periphery of cam hub 136. Cam shoulder 138 is generally of an undulating, harmonic curvilinear shape, and can be characterized as having a certain frequency, where frequency may generally refer to the number of occurrences of peaks and troughs about the 360-degree circumference of cam shoulder 138, a peak and abutting troughs together forming a lobe. In the electric device 10 as described herein, the cam shoulders need not be limited to a particular shape. However, in one or more embodiments, the amplitude of the peaks of each cam shoulder 138 of each cam 18a, 18b are the same, with the depth of the troughs and the height of the peaks being substantially equal, while in other embodiments, the depth of the troughs may differ from height of the peaks. Likewise, in some embodiments, the frequencies of the cams 18a, 18b may be the same, while in other embodiments, the frequencies of cams 18a, 18b may differ. By altering the depth of the troughs, the height of the peaks and the number of lobes, the power generation, as well as the waveform shape of the electrical output, from any given power generation assembly 20 engaging a cam 18 can be precisely controlled. In this regard, by altering the number of lobes and/or the shape of a cam 18, the function of a gearbox as used with prior art power alternators can be replicated, and thus, the need for a gearbox between the prior art alternator and a driving source (such as an internal combustion engine, wind turbine, water turbine or the like) can be eliminated. This in turn, eliminates the frictional losses that would otherwise arise from a gearbox, thus improving overall efficiencies of the power alternator of the current disclosure as compared to those power alternators of the prior art. For example, a cam 18 with only two lobes will result in slower reciprocation of a magnet of magnet assembly 22 through windings of a coil assembly 21 as described above, when compared to a cam 18 having more lobes. Thus, in one or more embodiments, by increasing the number of lobes of a cam 18, a higher electrical output may be achieved. Where electric device 10 is an electric motor, in one or more embodiments, by increasing the number of lobes of a cam 18, a higher revolution per minute (RPM) of driveshaft 12 can be achieved without the use of a gearbox. In the embodiment of FIG. 5a, each curvilinear shaped cam shoulder 138 extending around cam hub 136 is illustrated with two peaks, namely a first peak 140a and a second peak 140b, with a corresponding number of troughs 141 formed therebetween, such as a first trough 141a (not shown on cam 18b) and a second trough 141b (not shown on cam 18a). As such, the illustrated cam shoulder 138 creates two complete cycles about the 360-degree circumference of cam hub 136 and thus represents double harmonics. In other embodiments, cam shoulder 138 may have a different number of peaks 140 and troughs 141. In other words, the frequency of the curvilinear shape forming cam shoulder 138 may be selected to exhibit a desired number of peaks 140 and troughs 141 for a specific power generation requirement. Cam shoulder 138 is further characterized as having an inwardly facing track or first surface 142 and an outwardly facing track or second surface 144, as well as an outer circumferential surface 145. First and second surfaces 142, 144 may generally oppose one another on opposite sides of cam shoulder 138 and may be disposed for engagement by one or more engagement mechanisms such as first and second engagement mechanisms 86, 88. Each cam 18a, 18b may be mounted on driveshaft 12 so as to be aligned with a driveshaft index reference 146. In particular, each cam 18 may include a cam index 150, such as the first cam index 150a and second cam index 150b of cams 18a, 18b, respectively. In one or more embodiments, cams 18a, 18b are generally mounted on driveshaft 12 so that the indexes 150a, 150b are generally aligned with one another relative to a specific reference point 146 on driveshaft 12. When the indices 150a, 150b are aligned with one another, the opposing cams 18a, 18b mirror one another and the respective peaks 140 of the two cams 18a, 18b align with one another, meaning that the respective peaks and troughs occur at the same angular position about driveshaft 12 relative to reference point 146. As such, the peaks 140 of each cam 18a, 18b face one another and the troughs 141 of each cam 18a, 18b face one another. When the indices 150a, 150b are aligned, opposing magnet slide arms 28 as described above within a stator cylinder assembly 24 will move harmonically in unison. For the avoidance of doubt, references to cams 18 “mirroring” one another herein simply mean that the respective troughs or peaks occur at the same angular position about driveshaft 12, but not necessarily that the curvilinear shape of the cam shoulders 138a, 138b are the same. Finally, the top of each peak 140 corresponds with inner dead center (IDC) of stator cylinder assembly 24 (see FIG. 3), while the bottom of each trough 141 corresponds with outer dead center (ODC) of stator cylinder assembly 24. In other words, when a cam follower assembly 26 (see FIG.4A) engages a cam shoulder 138 at a lobe peak 140, the magnet slide arm 28 (see FIG.4A) driven by the cam follower assembly 26 is closest to IDC of stator cylinder 60 (see FIG.3). Likewise, when a cam follower assembly 26 (see FIG.4A) engages a cam shoulder 138 at a trough 141, the magnet slide arm 28 (see FIG.4A) driven by the cam follower assembly 26 is closest to ODC of stator cylinder 60 (see FIG.3). FIGS. 5b and 5c are illustrative cam profiles of cam shoulders 138a, 138b to better describe possible embodiments of the curvilinear shape of cam shoulders 138a, 138b. In one or more embodiments as illustrated in FIG.5b, the curvilinear shape may be a sinusoidal shape, with a peak 140 occurring equidistance between successive troughs 141, while in other embodiments as illustrated in FIG.5c, the curvilinear shape may be a segmented polynomial shape, with the peak 140 occurring between two successive troughs 141 but skewed or shifted closer to one trough 141. In any event, cam shoulder 138a may be associated with the first cam 18a and cam shoulder 138b may be associated with the second cam 18b. Each cam shoulder 138 forms a guide or track along which a cam follower (see FIG.4A) moves. As such, the shape of cam shoulder 138 governs reciprocating, axial movement of a corresponding magnet slides within a stator cylinder, such as stator cylinder 60 described above. The shoulder shape, as represented by the profiles of FIGS. 5a, 5b is therefore an important part of the operation of some embodiments of electric device 10. It will be appreciated that cam shoulders 138a, 138b are illustrated in FIGS.5b and 5c as they would oppose one another on driveshaft 12 when radially indexed to substantially mirror one another. As such, peaks 140 oppose one another and troughs 141 oppose one another so that the opposing features have approximately the same radial position on driveshaft 12 relative to the driveshaft index 146 (see FIG.5). Generally, each cam 18 has at least one lobe 151 formed of a peak 140 bounded by a trough 141. In the illustrated embodiment, each cam 18 is shown with a first lobe 151a and a second lobe151b. Each peak 140 has a maximum peak amplitude PA. Each lobe 151 has an overall wavelength distance W, defined as the distance between successive troughs 141 across a peak 140. Each trough 141 has a maximum trough depth TD. Moving clockwise along the circumference of a cam shoulder 138 (or left to right as shown in FIGS.5b and 5c), each lobe 151 has an ascending side or shoulder portion 153 and a descending side or shoulder portion 155. Additionally, in some embodiments, to ensure that the opposing magnet slide arms 28 driven by cams 18a, 18b are continuously moving, no portion of the curvilinear shaped shoulder of cam 18a is parallel with any portion of curvilinear shaped shoulder of cam 18b. As such, opposing curvilinear shaped cam shoulders 138a, 138b, whether of a sinusoidal shape or a segmented polynomial shape, are constantly diverging or converging from one another. In other words, no portion of cam shoulders 138a, 138b are parallel since this would result in a loss of momentum of movement of the opposing magnet slide arms 28 within the magnet slide chamber 23. With specific reference to FIG. 5b, cam 18a is shown as having a sinusoidal shaped cam shoulder 138a. As such, first lobe 151a ₁ is located approximately equidistance between a first trough 141a ₁ and a second trough 141a2. In particular, the maximum peak amplitude PAa ₁ occurs at approximately ½ the overall wavelength distance W for lobe 151a ₁ . As such, first lobe 151a ₁ is symmetrical in shape, illustrated by wavelength distance W _as of an ascending shoulder portion 153a ₁ from the first trough 141a ₁ to the peak or apex 143a ₁ of lobe 151a ₁ being equal to the wavelength distance Wds of descending shoulder portion 155a ₁ from the peak or apex 143a ₁ of lobe 151a ₁ to second trough 141a ₂ . First trough 141a ₁ has a trough depth TDa ₁ that is substantially the same as trough depth TDa ₁ of second trough 141a ₂ . Similarly, second lobe 151a2 is of substantially the same shape as first lobe 151a ₁ . In this regard, lobe 151a ₁ has an ascending shoulder portion 153a ₁ that is of substantially the same shape as descending shoulder portion 155a ₁ . As such, the absolute value of the average slope Sa ₁ of ascending shoulder portion 153a ₁ between trough 141a ₁ and peak 140a ₁ is approximately the same as the absolute value of the average slope Sa2 of descending shoulder portion 155a ₁ between peak 140a ₁ and trough 141a ₂ moving clockwise (left to right in Fig.5b) along cam shoulder 138a. As with cam 18a, cam 18b is shown as having a symmetrical sinusoidal shaped cam shoulder 138b. As such, first lobe 151b ₁ is located approximately equidistance between a first trough 141b ₁ and a second trough 141b ₂ . In particular, the maximum peak amplitude PAb ₁ occurs at approximately ½ the overall wavelength distance W for lobe 151b1. First trough 141b1 has a trough depth TDb ₁ that is substantially the same as trough depth TDb ₁ of second trough 141b ₂ . Similarly, second lobe 151b ₂ is of substantially the same shape as first lobe 151b ₁ . In this regard, lobe 151b1 has an ascending shoulder portion 153b1 that is of substantially the same shape as descending shoulder portion 155b1. As such, the absolute value of the average slope Sb ₁ of ascending shoulder portion 153b ₁ between trough 141b ₁ and peak 140b ₁ is approximately the same as the absolute value of the average slope Sb2 of descending shoulder portion 155b1 between peak 140b1 and trough 141b2 moving clockwise (left to right in Fig.5b) along cam shoulder 138b. In any event, cams 18a, 18b are angularly mounted on driveshaft 12 (see FIG. 5a) to mirror one another so that the lobes 151 of the respective cams opposed one another with corresponding peaks 140 in general alignment and the number of lobes 151a of cam 18a corresponds with the number of lobes 151b of cam 18b. In this regard, the opposing features may be angularly aligned with one another so that opposing peaks 140 and opposing troughs 141 generally occur at the same angular position about driveshaft 12 relative to index 146. Although in some embodiments, the opposing cam shoulders 138a, 138b of spaced apart cams 18a, 18b are generally disposed to have substantially the same sinusoidal shape, adjustments to portions of the shape of a particular shoulder, including the width of circumferential surface 145 and/or the shape of inwardly facing track 142 of a cam shoulder 138 may be utilized to adjust relative movements of opposing first and second magnet assemblies 22a, 22b, respectively, for a desired purpose. Thus, in some embodiments, the trough 141a ₁ of one cam 18a may be shaped to include a flat portion 147 that lies in a plane perpendicular to driveshaft axis 14 and the axis of cam hub 136 or otherwise be deeper than the corresponding opposing trough 141b ₁ of cam 18b, which is illustrated as generally curved through the entire trough 141b ₁ . In other words, the trough depth TDb ₁ of trough 141b ₁ is greater than opposing trough depth TDa ₁ of corresponding trough 141a ₁ . Similarly, peak 140a ₁ of cam 18a may have a rounded shape at its apex 143, while the shape of opposing peak 140b1 of cam 18b may have a flat portion 149 that lies in a plane perpendicular to driveshaft axis 14 and the axis of cam hub 136 at its corresponding apex 143. In the illustrated embodiments, because each flat portion 147, 149 of the corresponding cams 18a, 18b lies in a plane perpendicular to driveshaft axis 14 and the axis of cam hub 136, it will be appreciated that flat portions 147, 149 are in parallel planes. With specific reference to FIG.5c, cam 18a is shown as having a segmented polynomial shaped cam shoulder 138a. As such, first lobe 151a ₁ is asymmetrical in shape, with the maximum peak amplitude PAa ₁ occurring closer to second trough 141a2 as opposed to first trough 141a ₁ , illustrated by wavelength distance Was from the first trough 141a ₁ to the apex 143 of lobe 151a ₁ as being greater than the wavelength distance W _ds from the apex 143a ₁ of lobe 151a ₁ to second trough 141a2. In other words, wavelength distance Was from the first trough 141a ₁ to peak 140a ₁ of an ascending shoulder portion 153a ₁ of lobe 151a ₁ is greater than the wavelength distance W _ds from the peak 140a ₁ to the second trough 141a ₂ of a descending shoulder portion 155a ₁ of the lobe 151a ₁ . In these embodiments, first trough 141a ₁ has a trough depth TDa ₁ that is substantially the same as trough depth TDa ₂ of second trough 141a ₂ , which is substantially the same as maximum peak amplitudes PAa ₁ and PAa2 of lobes 151a ₁ and 151a2, respectively. Similarly, second lobe 151a ₂ is of substantially the same shape as first lobe 151a ₁ . However, because lobes 151a ₁ and 151a ₂ are asymmetrical, lobe 151a ₁ has an ascending shoulder portion 153a ₁ that is shallower in shape than the steeper shape of descending shoulder portion 155a ₁ . As such, the absolute value of the average slope Sa ₁ of ascending shoulder portion 153a ₁ between trough 141a ₁ and peak 140a ₁ is less than the absolute value of the average slope Sa ₂ of descending shoulder portion 155a ₁ between peak 140a ₁ and trough 141a2 moving clockwise along cam shoulder 138a. It will be appreciated that the steeper shape (or greater slope) of descending shoulder portion 155a ₁ results in faster movement of a corresponding magnet during a retraction stroke of a magnet assembly as compared to the extension stroke of a magnet assembly within a stator cylinder. Cam 18b is shown in FIG.5c as having a segmented polynomial shaped cam shoulder 138b. As such, first lobe 151b1 is asymmetrical in shape, with the maximum peak amplitude PAb1 occurring closer to second trough 141b ₂ as opposed to first trough 141b ₁ , illustrated by wavelength distance W _as from the first trough 141b ₁ to the apex 143b ₁ of lobe 151b ₁ as being greater than the wavelength distance Wds from the apex 143b1 of lobe 151b1 to second trough 141b2. In these embodiments, first trough 141b1 has a trough depth TDb1 that is substantially the same as trough depth TDb ₂ of second trough 141b ₂ , which is substantially the same as maximum peak amplitudes PAb1 and PAb2 of lobes 151b1 and 151b2, respectively. Similarly, second lobe 151b2 is of substantially the same shape as first lobe 151b1. However, because lobes 151b ₁ and 151b ₂ are asymmetrical, lobe 151b ₁ has an ascending shoulder portion 153b ₁ that is shallower in shape than the steeper shape of descending shoulder portion 155b ₁ . As such, the absolute value of the average slope Sb1 of ascending shoulder portion 153b1 between trough 141b ₁ and peak 140b ₁ is less than the absolute value of the average slope Sb ₂ of descending shoulder portion 155b ₁ between peak 140b ₁ and trough 141b ₂ moving clockwise (left to right in Fig.5c) along cam shoulder 138b. In any event, cams 18a, 18b are angularly mounted on driveshaft 12 relative to index 146 (see FIG.5a) to mirror one another so that the lobes 151 of the respective cams opposed one another with corresponding peaks 140 in general alignment and the number of lobes 151a of cam 18a corresponds with the number of lobes 151b of cam 18b. In this regard, the opposing features may be angularly aligned with one another so that opposing peaks 140 and opposing troughs 141 generally occur at the same angular position about driveshaft 12 relative to index 146. In one or more embodiments, each descending shoulder portion 155 of a segmented polynomial shaped cam shoulder 138 further includes a substantially linear portion 157 extending from each lobe apex 143 toward the second trough 141. While portion 157 may be linear or flat, it will be appreciated that it is not perpendicular to driveshaft axis 14 or the axis of cam hub 136 (and thus, a magnet slide continues to move as its associated cam follower moves across linear portion 157 during operation of electric device 10.) In other words, linear portion 157 has a slope greater than zero. In preferred embodiments, linear portion 157 has a slope of greater than zero and less than approximately 20 degrees. Thus, descending shoulder portion 155a ₁ of lobe 151a ₁ of cam 18a includes a linear portion 157a ₁ extending from apex 143a ₁ . Similarly, opposing cam 18b has a descending shoulder portion 155b ₁ of lobe 151b ₁ with a linear portion 157b ₁ extending from apex 143b ₁ . The other lobes 151a ₂ , 151b ₂ likewise include linear portions 157 as described. In one or more embodiments, opposing linear portions 157 have the same slope. In one or more embodiments, at least one, or both ascending shoulder portion 153 of a segmented polynomial shaped cam shoulder 138 may likewise include a substantially linear portion (not shown) similar to linear portion 157, extending from each lobe trough 141 extending towards an apex 143. Again, while such portion may be linear or flat, it will be appreciated that it is not perpendicular to driveshaft axis 14 or the axis of cam hub 136, and thus, a magnet continues to move within its stator cylinder as its associated cam follower moves across such linear portion and the slope of such portion would be greater than zero. The cam shoulders 138a, 138b of spaced apart cams 18a, 18b illustrated in FIG.5c are generally disposed to have substantially the same segmented polynomial shape at least along the opposing descending shoulder portions 155a ₁ , 155b ₁ . However, because the shape of the segmented polynomial shoulder governs movement of a magnet within a stator cylinder, and in particular, how fast a magnet moves within its stator cylinder, then the opposing ascending shoulder portion 153 of cams 18a, 18b may differ. As such, in one or more embodiments, the discreet slope Sa ₁ at any given point along the ascending shoulder portion 153a ₁ of cam 18a may differ from the discreet slope Sb1 at any given point along the ascending shoulder portion 153b1 of cam 18b. For example, the initial shape of ascending shoulder portion 153b1 adjacent trough 141b ₁ may be steeper than the initial shape of ascending shoulder portion 153a ₁ adjacent trough 141a ₁ , resulting in faster movement of the one magnet towards IDC and thus faster movement of the magnet as compared to the movement of the opposing magnet governed by ascending shoulder portion 153a ₁ . Regardless, it will be appreciated that for the overall segmented polynomial shape of opposing cam shoulders 138a, 138b, the trough depth TDa ₁ of trough 141a ₁ is substantially the same as the opposing trough depth TDb ₁ of corresponding trough 141b1. Similarly, peak 140a ₁ of cam 18a has substantially the same peak amplitude PAa ₁ as the peak amplitude PAb ₁ of opposing peak 140b ₁ . The length L of linear portion 157 may be selected to correspond with a particular desired waveform. It will be appreciated that while opposing cam shoulders 138a, 138b are constantly diverging or converging without any parallel portions of their respective segmented polynomial shapes, the opposing linear portions 157 of a shallow slope result in slower movement apart of opposing magnet assemblies in a stator cylinder, thereby permitting a substantially constant magnet slide chamber volume for a period of time without having the magnets stop in the stator cylinder. In one or more embodiments, opposing linear portions 157 have the same length L. However, it will be appreciated that in this embodiment, while the peak 140a of each lobe 151a of cam 18a is substantially aligned with the corresponding peak 140b of each lobe 151b of cam 18b, no portion of segmented polynomial shaped cam shoulder 138a is parallel with any portion of segmented polynomial shaped cam shoulder 138b. Likewise, the angular alignment of cams 18a, 18b relative to the driveshaft index reference 146, and also to one another, may be adjusted to achieve a particular purpose. Cam 18a may be angularly rotated a desired number of degrees relative to driveshaft index reference 146 (and cam 18b) in order to adjust the movement of the magnet slide arm 28 associated with cam 18a relative to the magnet slide arm 28 associated with cam 18b. In some embodiments, one cam 18, such as cam 18b, may be rotated approximately .5 to 11 degrees relative to the other cam 18, such as cam 18a. FIG. 6a illustrates a magnet assembly 22 engaged with cam 18a on a driveshaft 12 which includes an opposing cam 18b. While only one magnet assembly 22 is illustrated engaged with cam 18a, it will be appreciated that multiple magnet assemblies 22 may be engaged with cam 18a as described herein. Moreover, where an opposing cam 18b is mounted on driveshaft 12 as shown, cam 18b is likewise disposed for engagement by one or more magnet assemblies 22. For purposes of clarity, however only magnet assembly 22 as illustrated will be discussed. Specifically, cam follower assembly 26 engages cam 18a so that the shoulder 138 of cam 18a extends into opening 84 of cam follower assembly 26, allowing first roller 86 to engage inwardly facing track 142 of cam 18a and second roller 88 to engage outwardly facing track 144 of cam 18a. Adjustable spacer 90 bears against outer surface 145 of cam shoulder 138. Spacer 90 can be radially adjusted to correspondingly adjust the position and alignment of rollers 86, 88 on tracks 142, 144, respectively. Magnet assembly 22 is constrained to reciprocate along coil assembly axis 25 which is spaced apart from driveshaft axis 14 a distance D, which may be approximately the cam radius R _c . As such, rotational movement of driveshaft 12 about driveshaft axis 14 is translated into axial movement of magnet assembly 22, and thus, magnet 30, along coil assembly axis 25 by virtue of rotation of cams 18a and 18b. In the illustrated embodiment, it will be appreciated that the shape of cam shoulder 138 is generally sinusoidal and peak 140a of cam 18a has a rounded shape at its apex 143, while the corresponding surface of peak 140a of cam 18b has a linear or flat portion 149 (as described above) at its apex 143. In other embodiments, the cam shoulder 138 may have a segmented polynomial shape, in which case, opposing peaks 140 would be rounded at apex 143 of both cams 18 and opposing troughs 141 would likewise be similarly rounded at their bottom. FIG.6b illustrates a driveshaft 12 having only a single cam 18a mounted thereon and engaged by a single radial power generation assembly 20, with a magnet assembly 22 engaged with cam 18a. In the illustrated embodiment, magnet assembly 22 has a single cam follower assembly 26 that engages cam 18a in order to reciprocate a single magnet slide arm 28 relative to a stator cylinder assembly 24 so as to generate power. Cam follower assembly 26 engages cam 18a so that the shoulder 138 of cam 18a extends into opening 84 of cam follower assembly 26, allowing first roller 86 to engage inwardly facing track 142 of cam 18a and second roller 88 to engage outwardly facing track 144 of cam 18a. Adjustable spacer 90 bears against outer surface 145 of cam shoulder 138. Spacer 90 can be radially adjusted to correspondingly adjust the position and alignment of rollers 86, 88 on tracks 142, 144, respectively. Magnet assembly 22 is constrained to reciprocate along coil assembly axis 25 which is spaced apart from driveshaft axis 14 a distance D, which may be approximately the cam radius Rc. As such, rotational movement of driveshaft 12 about driveshaft axis 14 is translated into axial movement of magnet assembly 22, and thus, magnet 30, along coil assembly axis 25 by virtue of rotation of cam 18a, whereby the magnet slide arm 28 of magnet assembly 22 moves within stator cylinder 60. Specifically, the magnet 30 carried by magnet slide arm 28 is moved along coil assembly axis 25 within magnet slide chamber 32 formed in stator cylinder 60 of the stator cylinder assembly 24. Windings 68 are mounted along cylinder wall 66 of stator cylinder 60 around magnet slide chamber 32 and extend between a first winding edge 61 and a second winding edge 63. As magnet 30 moves within magnet slide chamber 32 of stator cylinder 60 between the winding edges 61, 63, current is generated within windings 68 in a manner well known in the industry. In the illustrated embodiment, it will be appreciated that the shape of cam shoulder 138 is generally sinusoidal and peak 140a of cam 18a has a rounded shape at its apex 143, while the corresponding surface of peak 140a of cam 18b has a linear or flat portion 149 (as described above) at its apex 143. In other embodiments, the cam shoulder 138 may have a segmented polynomial shape, in which case, opposing peaks 140 would be rounded at apex 143 of both cams 18 and opposing troughs 141 would likewise be similarly rounded at their bottom. Also shown in FIG. 6b is an electrical inverter 108 electrically connected to a power source 109 via electrical leads 29, which also interconnect electrical inverter 108 to windings 69 of the stator cylinder assembly 24 to convert alternating current generated by stator cylinder assembly 24 into direct current that can be stored by power source 109. In other embodiments, electrical inverter 108 may be eliminated. Power source 109 may be any device for storing an electric charge generated by a stator cylinder assembly 24 including without limitation, batteries, capacitors and the like. It will be appreciated that power source 109 may be utilized to operate electric device 10 whereby power source 109 may supply electrical current, either directly or through electrical inverter 108, to windings 69 in order to energize windings 69 to cause magnet slide arms 31 to reciprocate within their respective stator cylinders 47. A controller 111 may also be provided to control operation of power generation assembly 20, power source 109 and inverter 108. FIG.6c illustrates a driveshaft 12 having only a single cam 18a mounted thereon, with a magnet assembly 22 engaged with cam 18a. In the illustrated embodiment, magnet assembly 22 has a single cam follower assembly 26 that engages cam 18a, however, unlike the embodiment of FIG.6b, in order to generate power, cam follower assembly 26 reciprocates a first magnet slide arm 28a relative to a first stator cylinder assembly 24a and reciprocates a second magnet slide arm 28b relative to a second stator cylinder assembly 24b. Cam follower assembly 26 engages cam 18a so that the shoulder 138 of cam 18a extends into opening 84 of cam follower assembly 26, allowing first roller 86 to engage inwardly facing track 142 of cam 18a and second roller 88 to engage outwardly facing track 144 of cam 18a. Adjustable spacer 90 bears against outer surface 145 of cam shoulder 138. Spacer 90 can be radially adjusted to correspondingly adjust the position and alignment of rollers 86, 88 on tracks 142, 144, respectively. Magnet assembly 22, and in particular, magnet slide arms 28a, 28b, are constrained to reciprocate along coil assembly axis 25 which is spaced apart from driveshaft axis 14 a distance D, which may be approximately the cam radius R _c . As such, rotational movement of driveshaft 12 about driveshaft axis 14 is translated into axial movement of magnet assembly 22, and thus, magnet 30 carried on each of magnet slide arms 28a, 28b, along coil assembly axis 25 by virtue of rotation of cam 18a, whereby magnet slide arm 28a of magnet assembly 22 moves within stator cylinder 60a and magnet slide arm 28b of magnet assembly 22 moves within stator cylinder 60b. Specifically, the magnet 30 carried by each magnet slide arm 28 is moved along coil assembly axis 25 within its magnet slide chamber 32 formed its respective stator cylinder 60a, 60b of the stator cylinder assembly 24. Windings 68 are mounted along cylinder wall 66 of each stator cylinder 60a, 60b around magnet slide chamber 32 and extend between a first winding edge 61 and a second winding edge 63. As magnet 30 moves within magnet slide chamber 32 of its respective stator cylinder 60a, 60b between the winding edges 61, 63, current is generated within windings 68 in a manner well known in the industry. Thus, it will be appreciated that in this embodiment, a single cam 18a is utilized to actuate first and second magnets 30 disposed on opposite sides of cam shoulder 138 from one another along a single coil assembly axis 25. Also shown in FIG. 6c is an electrical inverter 108 electrically connected to a power source 109 via electrical leads 29, which also interconnect electrical inverter 108 to windings 69 of the stator cylinder assembly 24 to convert alternating current generated by stator cylinder assembly 24 into direct current that can be stored by power source 109. In other embodiments, electrical inverter 108 may be eliminated. Power source 109 may be any device for storing an electric charge generated by a stator cylinder assembly 24 including without limitation, batteries, capacitors and the like. It will be appreciated that power source 109 may be utilized to operate electric device 10 whereby power source 109 may supply electrical current, either directly or through electrical inverter 108, to windings 69 in order to energize windings 69 to cause magnet slide arms 31 to reciprocate within their respective stator cylinders 47. A controller 111 may also be provided to control operation of power generation assemblies 20, power source 109 and inverter 108. Controller 111 may be utilized to selectively energize one or both sets of electromagnetic coils 68 depending on the output requirements a power generation assembly 20 and electric device 10. For example, under certain output conditions for electric device 10, only one power generation assembly 20 shown in FIG. 6c may be energized, while under other output conditions, both power generation assembly 20 shown in FIG.6c may be utilized. In this same vein, one power generation assembly 20 shown in FIG. 6c may have a first coil density and the other power generation assembly 20 may have a second coil density different than the first coil density such that the power generation assemblies 20 when energized have different power outputs for driving cam 18a. Controller 111 may be utilized to selectively energize a set of windings 69 with a particular coil density depending on the desired power output at a particular time. FIG. 6d illustrates a driveshaft 12 having two cam 18a, 18b mounted thereon, with a magnet assembly 22 engaged with each of cams 18a, 18b. In the illustrated embodiment, magnet assembly 22a has a cam follower assembly 26a that engages cam 18a, while magnet assembly 22b has a cam follower assembly 26b that engages cam 18b. Each cam follower assembly 26 reciprocates first and second magnet slide arms 28 mounted opposite from one another about shoulder 138 of its respective cam 18a, 18b. Specifically, cam follower assembly 26a reciprocates a magnet slide arm 28a relative to a first stator cylinder assembly 24a and reciprocates magnet slide arm 28b relative to a second stator cylinder assembly 24b. Likewise, cam follower assembly 26b reciprocates a magnet slide arm 28c relative to a third stator cylinder assembly 24c and reciprocates a magnet slide arm 28d relative to stator cylinder assembly 24b. Thus, stator cylinder assembly 24b is disposed to receive magnet slide arm 28b within a first end 62 and magnet slide arm 28d within a second end 64. With respect to stator cylinder assembly 24b, a stator cylinder 60b extending between the first end 62 and the second end 64 and generally formed of a cylinder wall 66. A first set of electromagnetic coils or windings 68 is disposed along cylinder wall 66 between the first and second ends 62, 64, as are a second set of windings 70, spaced apart from first set of windings 68. In other embodiments, stator cylinder assembly 24b may be replaced with two separate stator cylinder assemblies 24 having only a single set of windings 68, such as stator cylinder assembly 24a. Cam follower assembly 26a engages cam 18a so that the shoulder 138 of cam 18a extends into opening 84 of cam follower assembly 26a, allowing first roller 86 to engage inwardly facing track 142 of cam 18a and second roller 88 to engage outwardly facing track 144 of cam 18a. Adjustable spacer 90 bears against outer surface 145 of cam shoulder 138. Spacer 90 can be radially adjusted to correspondingly adjust the position and alignment of rollers 86, 88 on tracks 142, 144, respectively. Magnet assembly 22a, and in particular, magnet slide arms 28a, 28b of magnet assembly 22a, are constrained to reciprocate along coil assembly axis 25 which is spaced apart from driveshaft axis 14 a distance D, which may be approximately the cam radius R _c . As such, rotational movement of driveshaft 12 about driveshaft axis 14 is translated into axial movement of magnet assembly 22a, and thus, magnet 30 carried on each of magnet slide arms 28a, 28b, along coil assembly axis 25 by virtue of rotation of cam 18a, whereby magnet slide arm 28a of magnet assembly 22a moves within stator cylinder 60a and magnet slide arm 28b of magnet assembly 22a moves within stator cylinder 60b. Specifically, the magnet 30 carried by each magnet slide arm 28a, 28b is moved along coil assembly axis 25 within its respective stator cylinder 60a, 60b of the stator cylinder assembly 24a, 24b. Windings 68 are mounted along cylinder wall 66 of each stator cylinder 60a, 60b. As each magnet 30 moves within its respective stator cylinder 60a, 60b, current is generated within each set of windings 68 in a manner well known in the industry. Similarly, cam follower assembly 26b engages cam 18b so that the shoulder 138 of cam 18b extends into opening 84 of cam follower assembly 26b, allowing first roller 86 to engage inwardly facing track 142 of cam 18b and second roller 88 to engage outwardly facing track 144 of cam 18b. Adjustable spacer 90 bears against outer surface 145 of cam shoulder 138. Spacer 90 can be radially adjusted to correspondingly adjust the position and alignment of rollers 86, 88 on tracks 142, 144, respectively. Magnet assembly 22b, and in particular, magnet slide arms 28a, 28b of magnet assembly 22b, are constrained to reciprocate along coil assembly axis 25 which is spaced apart from driveshaft axis 14 a distance D, which may be approximately the cam radius Rc. As such, rotational movement of driveshaft 12 about driveshaft axis 14 is translated into axial movement of magnet assembly 22b, and thus, magnet 30 carried on each of magnet slide arms 28c, 28d, along coil assembly axis 25 by virtue of rotation of cam 18b, whereby magnet slide arm 28c of magnet assembly 22b moves within stator cylinder 60c and magnet slide arm 28d of magnet assembly 22b moves within stator cylinder 60b. Specifically, the magnet 30 carried by each magnet slide arm 28c, 28d is moved along coil assembly axis 25 within its respective stator cylinder 60c, 60b of the stator cylinder assembly 24c, 24b. Windings 68 are mounted along cylinder wall 66 of stator cylinder 60c around magnet slide chamber 32, while windings 70 are mounted along cylinder wall 66 of stator cylinder 60b, spaced apart from windings 68 of stator cylinder 60b. As each magnet 30 moves within its respective stator cylinder 60a, 60b, current is generated within each set of windings 68, 70, respectively, in a manner well known in the industry. Thus, it will be appreciated that in this embodiment having two spaced apart cams 18a, 18b, aligned along a given coil assembly axis 25 are at least three stator cylinder assemblies 24a, 24b, 24c disposed to receive four magnet slide arms 28a, 28b, 28c, 28d, each of which carries magnets 30 to energize windings 68, 70 as described. Also shown in FIG. 6d is an electrical inverter 108 electrically connected to a power source 109 via electrical leads 29, which also interconnect electrical inverter 108 to windings 69 of the stator cylinder assembly 24 to convert alternating current generated by stator cylinder assembly 24 into direct current that can be stored by power source 109. In other embodiments, electrical inverter 108 may be eliminated. Power source 109 may be any device for storing an electric charge generated by a stator cylinder assembly 24 including without limitation, batteries, capacitors and the like. It will be appreciated that power source 109 may be utilized to operate electric device 10 whereby power source 109 may supply electrical current, either directly or through electrical inverter 108, to windings 69 in order to energize windings 69 to cause magnet slide arms 31 to reciprocate within their respective stator cylinders 47. A controller 111 may also be provided to control operation of power generation assemblies 20, power source 109 and inverter 108. Controller 111 may be utilized to selectively energize one or more sets of electromagnetic coils 68 depending on the output requirements a power generation assembly 20 and electric device 10. For example, under certain output conditions for electric device 10, only a limited or select number of power generation assembly 20 shown in FIG. 6d may be energized, while under other output conditions, all power generation assemblies 20 shown in FIG. 6d may be utilized. In this same vein, one or more power generation assemblies 20 shown in FIG.6d may have a first coil density and the other power generation assemblies 20 may have a second coil density different than the first coil density such that the power generation assemblies 20 when energized have different power outputs for driving cam 18a. Controller 111 may be utilized to selectively energize a set of windings 69 with a particular coil density depending on the desired power output at a particular time. In this regard, during operation of electric device 10, controller 111 may be used to dynamically switch back and forth between power generation assemblies 20 or may be used to operate all power generation assemblies 20 depending on the output requirements of electric device 10 during a particular stage of operation. FIGS.7a and 7b illustrate the stator cylinder assemblies 24 of power generation assemblies 20 symmetrically positioned around driveshaft 12. While stator cylinder assemblies 24 are generally supported by enclosure 53 (see FIG.1), for ease of depiction, the enclosure 53 is not shown in FIGS.7a and 7b. In one embodiment, six stator cylinder assemblies 24a, 24b, 24c, 24d, 24e and 24f are utilized, although fewer or more stator cylinder assemblies 24 could be incorporated as desired. In any event, the stator cylinder assemblies 24a-24f are positioned around driveshaft 12 between cams 18a, 18b. It will be understood that for ease of description, while only one power generation assembly 20a is illustrated (having stator cylinder assembly 24a with magnet assemblies 22a, 22b disposed therein), each of the stator cylinder assemblies 24 depicted are disposed to receive at least one magnet assembly 22 together forming a power generation assembly 20. In any event, a first magnet assembly 22a and a second magnet assembly 22b which magnet assemblies 22a, 22b are axially aligned with one another within a stator cylinder assembly 24a. Cams 18a, 18b are mounted on driveshaft 12 so that the cams 18a, 18b are aligned to generally mirror one another. Each magnet assembly 22a, 22b within stator cylinder 60 moves between ODC to a position adjacent IDC. It will be appreciated that the length of the stroke of a magnet slide arm 28 within cylinder 60, and more specifically, the degree of movement of a magnet 30 relative to the length of the windings 68 of a stator cylinder assembly 24, can be utilized to adjust the electrical current generated by power generation assembly 20. Rotation of cams 18a, 18b drives first magnet assembly 22a and second magnet assembly 22b away from one another along the axis 71 of stator cylinder assembly 24a towards ODC. Stator cylinder 60 constrains each magnet assembly 22a, 22b to axial reciprocation along axis 71. Rotational movement of driveshaft 12 about driveshaft axis 14 (as driven by an external power source) results in rotation of cams 18a and 18b which translates the rotational movement into axial movement of magnet assemblies 22a, 22b along axis 71 as the rollers 86, 88 of respective cam follower assemblies 26a, 22b move along the tracks 142, 144 of their respective cams 18a, 18b. While cams 18a, 18b generally mirror one another, as explained above, in some embodiments where shoulder 143 has a sinusoidal shape, the trough 141a of cam 18a may be shaped to include a flat portion 147 (a portion that lies in a plane perpendicular to driveshaft axis 14) relative to corresponding opposing trough 141b of cam 18b, which is illustrated as generally curved through the entire trough 141b, causing magnet slide arm 28a to have a different momentary displacement in stator cylinder 60 relative to magnet slide arm 28b. In particular, as shown, as cam follower assembly 26a reaches flat portion 147 of track 142 of cam 18a, magnet slide arm 28a will remain retracted at outer dead center (“ODC”) momentarily even as magnet slide arm 28b continues to translate as its cam follower assembly 26b moves along track 142 of cam 18b and back towards IDC. A similar phenomenon occurs when cam followers 26a, 26b reach an apex 143 of their respective cams 18a, 18b. As described, the apex 143b of cam 18b includes a flat portion 149 (a portion that lies in a plane perpendicular to driveshaft axis 14) relative to corresponding opposing apex 143a of cam 18a, which is illustrated as generally curved through the entire apex 143a, causing magnet slide arm 28b to have a different displacement in stator cylinder 60 relative to magnet slide arm 28a. In particular, as cam follower assembly 26b reaches flat portion 149 of track 142 of cam 18b, magnet slide arm 28b will remain extended towards inner dead center (“IDC”) momentarily even as magnet slide arm 28a continues to translate as its cam follower assembly 26a moves along track 142 of cam 18a and back towards ODC. It will be appreciated in other embodiments, it may be desirable to ensure that each magnet slide arm 28 is continuously moving within stator cylinder 60, in which case, the shape of shoulder 138 does not include a portion that lies in a plane perpendicular to driveshaft axis 14. Thus, by utilizing the shape of shoulders 138 of opposing cams 18a, 18b, the relative translation of magnet slide arms 28a, 28b can be adjusted to achieve a desired goal, such as controlling the shape of the waveform generated by virtue of movement of a magnet slide arm 28. In other words, the cams 18a, 18b control the waveform shape utilizing the curvilinear shape of cam shoulder 138 to provide desired timing for the magnet slide arms 28 as they translate within their stator cylinders 60. In addition, or alternatively, to using the shape of cam shoulders 138 to adjust relative axial movement of magnet slide arms 28a, 28b, it will be appreciated that cam 18a can be radially displaced on driveshaft 12 relative to cam 18b, thereby achieving the same objective described above. Cams 18 may be located on driveshaft 12 with a small angular displacement with respect to each other in order to cause one of magnet slide arms 28 to be displaced in the stator cylinder 60 slightly ahead or behind its opposing magnet slide arm 28. This asymmetric magnet slide phasing feature can be used to enhance power generation operations, particularly as may be desirable when different waveforms or outputs are desired from electric device 10. In FIG. 7b, power generation assembly 20a is depicted as having a stator cylinder assembly 24a and a magnet assembly 22a. Stator cylinder assembly 24a includes a stator cylinder 60 disposed to carry windings 68. Likewise, magnet assembly 22a includes a magnet slide arm 28 on which is mounted a magnet 30. It will be appreciated that as illustrated by stator assemblies 24b-24f, additional power generation assemblies 20 may be deployed about driveshaft 12 by simply increasing the cam diameter CD of cam shoulder 138. In some embodiments, where high torque is required, cam shoulder 138 may be large, with a corresponding large plurality of power generation assemblies 20. FIG.8 illustrates the stator cylinder assemblies 24a-24f and driveshaft 12 of FIG.7a in relation to enclosure 53. Thus, as shown, enclosure 53 is positioned about driveshaft 12 between cam 18a and cam 18b. Enclosure 53 is generally extends between a first end 162 and a second end 164 and includes an annular guide body portion 160 therebetween, which annular guide body portion 160 is characterized by an exterior surface 166. A central driveshaft bore 172 extends between ends 162, 164. Likewise, two or more symmetrically positioned cylinder bores 174 extend between ends 162, 164 and are radially spaced outward of central driveshaft bore 172. In the illustrated embodiment, enclosure 53 has six cylinder bores 174 symmetrically spaced about driveshaft bore 172, of which cylinder bores 174a, 174b 174c and 174f are visible. Disposed in each cylinder bore 174 is a stator cylinder assembly 24, and thus, illustrated are stator cylinder assemblies 24a, 24b, 24c and 24f. As such, enclosure 53 supports the stator cylinder assemblies 24. Opposing cam follower assemblies 26a, 26b are illustrated as engaging their respective cams 18a, 18b and extending along axis 71 into the stator cylinder assembly 24a supported in cylinder bore 174a of enclosure 53. FIG.9 illustrates the stator cylinder assemblies 24a-24f, driveshaft 12, cam follower assemblies 26a, 26b, cams 18a, 18b and enclosure 53 of FIG. 8, but with guidance caps disposed for supporting cam follower assemblies 26. In particular, a first guidance cap 198 is deployed around driveshaft 12 between its first end 46 and cam 18a, and a second guidance cap 199 deployed around driveshaft 12 between its second end 50 and cam 18b. Each guidance cap 198, 199 generally includes a central bore 201 through which driveshaft 12 extends and two or more symmetrically positioned bores 204 radially spaced outward of central bore 201 with each bore 204 corresponding with and axially aligned with an adjacent stator cylinder assembly 24 supported by enclosure 53 (in some embodiments). In one or more embodiments, a guidance cap 198, 199 may be a plate with the above described bores 201, 204 formed therein. In other embodiments, a guidance cap 198, 199 may be a plate with support cylinders passing through the plate to form each guide bore 204. The support cylinders may, in turn, seat in corresponding cylindrical-shaped reliefs formed in sump casings 54, 56, thereby providing additional support to guidance caps 198, 199. In the illustrated embodiment, each guidance cap 198, 199 has six bores 204, namely 204a, 204b, 204c, 204d, 204e and 204f, symmetrically spaced about central bore 201. Each bore 204 is disposed to receive a cam follower assembly 26 to provide support to the cam follower assembly 26 as it reciprocates into and out of its respective stator cylinder assembly 24. In particular, as shown, the bore 204 is sized to correspond with the smaller diameter cylindrical end 76 of cam follower assembly 26, allowing the smaller diameter cylindrical end 76 to magnet slide within bore 204 as magnet slide arm 28 reciprocates in stator cylinder assembly 24. In addition, one or both guidance caps 198, 199 may be utilized to inject lubricating and cooling oil into to port 98 of the cam follower assembly 26. In particular, the guidance caps may be used to transfer the oil from an oil pump (not shown) to bearings 87, 89 of cam follower assembly 26. Each guidance cap 198, 199 may include one or more ports 203 utilized to transfer the oil to port 98 of the cam follower assembly 26. FIG. 10 is a perspective view of linear electric device 10. In the illustrated embodiment, electric device 10 is generally encased by enclosure 53 and supported by a first support block 212 at one end of the linear electric device 10 and a second support block 214 at the opposite end of the linear electric device 10. In this regard, sump casing 54 cooperates with first support block 212 to enclose enclosure 53 around the first end 46 of driveshaft 12 forming an oil lubrication and cooling chamber for providing oil to cam 18a and its associated cam follower assemblies 26, while sump casing 56 cooperates with second support block 214 to enclose enclosure 53 around the second end 50 of driveshaft 12 forming an oil lubrication and cooling chamber for providing oil to cam 18b and its associated cam follower assemblies 26. An oil port 218 may be provided in each of support block 212, 214 or sump casing 54, 56. A first flange 44 may be attached to a driveshaft 12 with a flywheel 52 mounted on first flange 44. As described above, an external driving force (not shown), such as an internal combustion engine, wind turbine, water turbine or other drive system may be provided to drive rotation of driveshaft 12 where electric device 10 is an alternator. Turning to FIGS. 11a-11c, the operation of linear electric device 10 will be described with reference to a system of four stator cylinder assemblies 24, of which stator cylinder assembly 24a will be the primary focal point, with references to stator cylinder assemblies 24b and 24d. Generally depicted is driveshaft 12 on which is mounted cams 18a and 18b, each having a curvilinear shaped shoulder 138. In the illustrated embodiment, each of cams 18a, 18b has two lobes 151 formed by two peaks 140 and two troughs 141 and are disposed on driveshaft so as to be radially aligned, i.e., without a radial offset of one cam 18 relative to the other cam. A cam follower assembly 26a engaged cam 18a and a cam follower assembly 26b engages cam 18b so that roller 86 of the respective cam follower assemblies 26a, 26b engage the inwardly facing track 142 of the shoulder 38 of each cam 18a, 18b. Cam follower assembly 26a reciprocates a magnet slide arm 28a and magnet 30a within stator cylinder 60 of cylinder assembly 24a, while cam follower assembly 26b reciprocates a magnet slide arm 28b and magnet 30b within stator cylinder 60. First guidance cap 198 supports cam follower assembly 26a while second guidance cap 199 supports cam follower assembly 26b. Each stator cylinder assembly 24 includes a first set of windings 68 provided along cylinder wall 66 between the first and second ends 62, 64 and a second set of windings 70 provided along cylinder wall 66 and spaced apart from first set of windings 68. Windings 68 have an outer winding edge 61 closest to the first end 62 and an inner winding edge 63 closest to second end 64, while windings 70 have an outer winding edge 65 closest to the second end 64 and an inner winding edge 67 closest to first end 62. Movement of magnet 30a within stator cylinder 60 will be described relative to cam 18a and windings 68. Movement of magnet 30b within stator cylinder 60 will be described relative to cam 18b and windings 70. Although two sets of windings 68, 70 are illustrated, it will be appreciated that as described above in FIG. 3a, only one set of windings may be provided in other embodiments. In the illustrated embodiment, the windings 68, 70 are spaced apart from one another so that each set of windings cooperates with its own magnet slide arm 28a, 28b, respectively, while in other embodiments, each magnet slide arm 28 may cooperate with multiple sets of windings as the magnet slide arm 28 translates within stator cylinder 60. The area between opposing magnet slide arms 28a, 28b within stator cylinder 60 forms magnet slide chamber 32 with at least a portion of the windings 68 disposed around magnet slide chamber 32. Inner dead center (IDC) and outer dead center (ODC) relative to the magnet slide arm 28 for stator cylinder assembly 24a are indicated. FIG.11a illustrates the magnet slide arms 28a, 28b extended in their respective strokes so as to be closest to IDC, where each magnet slide arm 28a, 28b is at its innermost axial position within stator cylinder 60. In this position, each cam follower assembly 26a, 26b engages its respective cam 18a, 18b at a peak 140. In this position, magnet 30a of magnet slide arm 28a has been translated substantially through windings 68, whereby the magnet 30a is positioned closest to IDC within magnet slide chamber 32. Likewise, magnet 30b of magnet slide arm 28b has been substantially translated through windings 70, whereby the magnet 30b is positioned closest to IDC within magnet slide chamber 32 and adjacent magnet 30a. In this position, driveshaft 12 is illustrated as being at a reference angle of 0°. Moreover, magnet assemblies 22b, 22d are shown at a point farthest from IDC in their respective stator cylinder assemblies 24b, 24d, respectively. In FIG. 11b, as driveshaft 12 rotates, cams 18a, 18b likewise rotate and each cam follower assembly 26a, 26b begins to move along a descending portion of the shoulder track of their respective cams 18a, 18b. In doing so, the rotational motion of the cams 18a, 18b is converted into axial motion of the cam follower assembly 26. The result is that magnet slide arms 28a, 28b within stator cylinder 60 of stator cylinder assembly 24a begin to move axially away from one another (as shown by the arrows) in a retraction stroke. At this point in the retraction stroke, both magnets 30a, 30b begin to move past the windings 68, 70 with which the respective magnet slide arms 28a, 28b cooperate. As described above, the speed of movement of the respective magnet slide arms 28a, 28b can be adjusted by adjusting the slope of the descending portion of a cam 18. In the illustrated embodiment, the magnet slide arms 28 within stator cylinder assembly 24d have now moved to an IDC position, while the magnet slide arms 28 within stator cylinder assembly 24b remain retracted relative to IDC. Thus, as shown each individual power generation assembly 20 may be at a different stage of power generation depending on the orientation of cams 18 and the relative engagement of cam follower assemblies 26 with the cams 18. In FIG.11c, each magnet slide arm 28a, 28b reaches ODC of stator cylinder assembly 24a by virtue of cam follower assemblies 26a, 26b reaching the bottom of the troughs 141 of their respective cams 18a, 18b. When magnet slide arms 28a, 28b are at ODC, their respective magnets 30a, 30b may have been retracted relative to their respective windings 68, 70 so that power generation in power generation assembly 20a temporality ceases, although, as will be appreciated, power generation associated with stator cylinder assemblies 24b, 24d continues. In this regard, the magnet slide arms 28 of stator cylinder assembly 24b are shown moving inward towards IDC, while magnet slide arms 28 of stator cylinder assembly 24d are shown moving outward towards ODC, although not as retracted as magnet slide arms 28 of stator cylinder assembly 24a. In the illustrated embodiment, cams 18a, 18b are depicted with substantially sinusoidal shaped cam shoulders 138a, 138b, and as such, as described above, it will be observed that on the one side of the linear electric device 10, a portion 147 of trough 141 of cam 18a is flattened (as compared to opposing trough 141 of cam 18b which is rounded). Turning to FIG. 12, an alternative embodiment of linear electric device 10 is illustrated, wherein two or more power generation assemblies 200, such as power generation assemblies 200a, 200b, are axially aligned in series along coil assembly axis 25, together forming a coil assembly series 202, such as coil assembly series 202a. Specifically, in FIG.12, driveshaft 12 extends along a driveshaft axis 14 and passes axially through the center of the linear electric device 10. Driveshaft 12 is supported by a pair of bearings 16a, 16b in a fixed axial position. Positioned along driveshaft 12 in spaced apart relationship to one another are at least three harmonic cams 218a, 218b, 218c, such as the cams 18 described above. Each power generation assembly 200 is comprised of a first magnet assembly 222a and a second magnet assembly 222b which magnet assemblies 222a, 222b are axially aligned with one another within a stator cylinder assembly 224a disposed along coil assembly axis 25. Coil assembly axis 25 is spaced apart from but generally parallel with driveshaft axis 14 of driveshaft 12. Magnet assembly 222a includes a cam follower assembly 226a attached to a magnet slide arm 228a to which is mounted a magnet 230a. Likewise, opposing magnet assembly 222b includes a cam follower assembly 226b attached to a magnet slide arm 228b to which is mounted a magnet 230b. Each cam follower assembly 226a, 226b engages its respective cam 218a, 218b and acts on its respective magnet slide arm 228a, 228b. Opposed magnet slide arms 228a, 228b within stator cylinder assembly 224a generally define a magnet slide chamber 232a therebetween within at least one set of windings 268a through which magnets 230a, 230b translate. Power generation assembly 200b of coil assembly series 202a likewise includes a first magnet assembly 222c and a second magnet assembly 222d which magnet assemblies 222c, 222d are axially aligned with one another within a stator cylinder assembly 224b disposed along a coil assembly axis 25. Magnet assembly 222c includes a magnet slide arm 228c to which is mounted a magnet 230c. Opposing magnet assembly 222d includes a cam follower assembly 226d attached to a magnet slide arm 228d to which is mounted a magnet 230d. Opposed magnet slide arms 228c, 228d within stator cylinder assembly 224b generally define a magnet slide chamber 232b within at least one set of windings 268b and through which magnets 230c, 230d translate. Thus, power generation assembly 200a is axially aligned with power generation assembly 200b so that their respective stator cylinder assemblies 224a, 224b are positioned in series along coil assembly axis 25. Cam follower assembly 226b may include a cam follower bridge 227 interconnecting magnet slide arm 228c to cam follower assembly 226b of magnet assembly 222b. Each cam follower assembly 226a, 226b, 226d engages its respective cam 218a, 218b, 218c and is movable with respect to its respective cam 218a, 218b, 218c so that radial rotation of the respective cams 218a, 218b, 218d via rotation of driveshaft 12 can be translated into axial movement of magnet slide arms 228a, 228b and 228d. Each cam follower assembly 226 may include an engagement mechanism, such as engagement mechanisms 286, 287 and 289 as shown. In some embodiments, one or more engagement mechanisms 286, 287, 289 may be rollers as described above. Further, because cam follower bridge 227 interconnects magnet assemblies 222b and 222c, radial rotation of cam 218b is utilized to drive axial movement of magnet slide arm 228c. In this regard, the second roller 289 of cam follower assembly 226b may be of a larger diameter than the second roller 287 of the other cam followers, since both rollers 286, 289 of cam follower assembly 226b are used to transfer load from cam 218b. Thus, rollers 286, 289 may be larger in diameter than rollers 287 in order to transfer load. Additionally, cam 218b may have an inwardly facing track 142 and an outwardly facing track 144 that are shaped the same as the corresponding track inwardly facing track of cam 218a and 218c In some embodiments, linear electric device 10 includes at least two coil assembly series 202 symmetrically spaced about driveshaft axis 14, such as coil assembly series 202a and 202b. In one or more embodiments, linear electric device 10 includes at least three symmetrically spaced coil assembly series 202, while in other embodiments, linear electric device 10 incudes at least four symmetrically spaced coil assembly series 202. Moreover, while two serially aligned stator cylinder assemblies 224 with three corresponding cams 18 have been described, the disclosure is not limited in this regard. Thus, in other embodiments three or more stator cylinder assemblies 224 may be axially aligned in series along coil assembly axis 25, with a cam 18 disposed between adjacent stator cylinder assemblies 224, as well as a cam 18 disposed at opposing ends of the series of stator cylinder assemblies 224. Turning to FIG. 13a, an alternative embodiment of linear electric device 10 (of FIG. 1) is illustrated as linear electric device 400, wherein two or more power generation assemblies 402, such as power generation assemblies 402a, 402b, are positioned to be parallel with driveshaft 12 but at different diameters about driveshaft 12, and as such, utilize two or more cam pairs of different diameters mounted on driveshaft 12. As shown, driveshaft 12 extends along a driveshaft axis 14. Mounted along driveshaft 12 between driveshaft ends 412 and 413, in spaced apart relationship to one another, are at least four harmonic cams 418a, 418b, 418c and 418d, such as the cams 18 described above, with cams 418a, 418b forming a first set of cams or cam pair and cams 418c, 418d forming a second set of cams or cam pair. The cams 18 of each set oppose one another as generally described above. However, cams 18a, 18b of the first cam set have a first cam set diameter D ₁ (defined as R1*2) while cams 18c, 18d of the second cam set have a second cam set diameter D ₂ (defined as R ₂ *2) that is greater than the first cam set diameter D ₁ . In some embodiments, power generation assemblies 402a, 402b may have the same angular position about driveshaft 12 so as to be generally adjacent one another, but radially spaced apart from one another in the same plane extending radially from driveshaft 12, while in other embodiments, power generation assemblies 402a, 402b may have different angular position about driveshaft 12. More specifically, power generation assembly 402a is comprised of a first magnet assembly 422a and a second magnet assembly 422b which magnet assemblies 422a, 422b are axially aligned with one another within a stator cylinder assembly 424a disposed along a coil assembly axis 25a. Stator cylinder assembly 424a is formed of a stator cylinder 460a extending between a first end 462a and a second end 464a and windings 468a disposed along stator cylinder 460a. Coil assembly axis 25a is spaced apart from, but generally parallel with, driveshaft axis 14 of driveshaft 12. Magnet assembly 422a includes a cam follower assembly 426a attached to a magnet slide arm 428a to which is mounted a magnet 430a. Likewise, opposing magnet assembly 422b includes a cam follower assembly 426b attached to a magnet slide arm 428b to which is mounted a magnet 430b. Each cam follower assembly 426a, 426b includes a first engagement mechanism 486 and a second engagement mechanism 487 and straddles its respective cam 418a, 418b so that engagement mechanisms 486, 487 engage the cam 18. Each cam follower assembly 426a, 426b acts on its respective magnet slide arms 428a, 428b. Opposed magnet slide arms 428a, 428b within stator cylinder assembly 424a generally define a magnet slide chamber 432a within at least one set of windings 468a and through which magnets 430a, 430b translate. Power generation assembly 402b likewise is comprised of a first magnet assembly 422c and a second magnet assembly 422d which magnet assemblies 422c, 422d are axially aligned with one another within a stator cylinder assembly 424b disposed along a coil assembly axis 25b. Stator cylinder assembly 424b is formed of a stator cylinder 460b extending between a first end 462c and a second end 464d and windings 468b disposed along stator cylinder 460b. Coil assembly axis 25b is spaced radially outward from, but generally parallel with coil assembly axis 25a of magnet slide arms 428a, 428b. Magnet assembly 422c includes a cam follower assembly 426c attached to a magnet slide arm 428c to which is mounted a magnet 430c. Likewise, opposing magnet assembly 422d includes a cam follower assembly 426d attached to a magnet slide arm 428d to which is mounted a magnet 430d. Each cam follower assembly 426c, 426d straddles its respective cam 418c, 418d and acts on its respective magnet slide arms 428c, 428d. Opposed magnet slide arms 428c, 428d within stator cylinder assembly 424b generally define a magnet slide chamber 432b within at least one set of windings 468b and through which magnets 430c, 430d translate. Thus, the stator cylinder 460a associated with power generation assembly 402a is spaced apart from driveshaft 12 at a first radius R ₁ and the stator cylinder 460b associated with power generation assembly 402b is spaced apart from driveshaft 12 at a second radius R ₂ , where the second radius R ₂ is greater than the first radius R1. In some embodiments, therefore, a plurality of first stator cylinders 460a may be spaced about driveshaft 12 at the first radius R1 and a plurality of second stator cylinders 460b may be spaced about driveshaft 12 at the second radius R ₂ . In one or more embodiments, magnet slide arms 428c, 428d are longer than magnet slide arms 428a, 428b, it being appreciated that the cams 418c, 418d are spaced farther apart from one another on driveshaft 12 than cams 418a, 418b, thus requiring longer magnet slides to permit the corresponding magnet assemblies 422c, 422d to engage cams 418c, 418d, respectively. In this regard, the lengths of the shafts 104 (see FIG.3) of the various magnet slide arm 428 may be adjusted as desired. Each cam follower assembly 426a, 426b, 426c and 426d straddles its respective cam 418a, 418b, 418c, 418d and is movable with respect to its respective cam 418a, 418b, 418c, 418d so that radial rotation of the respective cams 418a, 418b, 418c, 418d resulting from rotation of driveshaft 12 can translate into axial movement of magnet slides 430a, 430b, 430c and 430d. In one or more embodiments, each cam 418 further includes a circumferential shoulder 438 extending around the cylindrical periphery of a cam hub 436. Shoulder 438 is generally curvilinear in shape and can be characterized as having a certain frequency, where the frequency may generally refer to the number of occurrences of repeating peaks and troughs about the 360-degree circumference of the circumferential shoulder 438. In some embodiments, the curvilinear shape of shoulders 438 of the first cam 418a and second cam 418b are of a first frequency and the curvilinear shape of shoulders 438 of the third cam 418c and fourth cam 418d are of a second frequency, which in some embodiments may differ from the first frequency, permitting different power generation assemblies 402 to have different electrical and/or waveform outputs. In some embodiments, it may be desirable for magnet slide arms 428a, 428b, 428c and 428d to translate in unison. In such case, the second frequency is less than the first frequency. In other embodiments, it may be desirable for magnet slide arms 428c and 428d to translate more rapidly than magnet slide arms 428a and 428b, in which case, the second frequency may be equal to or greater than the first frequency. Similarly, in one or more embodiments, the amplitude of the curvilinear shoulders 438 of each cam 418a, 418b, 418c, 418d are the same, with the depth of the troughs and the height of the peaks being substantially equal, while in other embodiments, the depth of the troughs may differ from height of the peaks, permitting different power generation assemblies 402 to have different electrical and/or waveform outputs. In some embodiments, the amplitude of the third and fourth cams 418c, 418d, respectively is less than the amplitude of the first and second cams 418a, 418b in order to adjust timing of the respective magnet slide arms 428a, 428b, 428c and 428d. Because cams 418a, 418b of the first cam set have a different diameter D ₁ than the diameter D ₂ of cams 418c, 418d, shoulders 438 of the respective cams 418 are at different diameters. As such, magnet slide arms 428a, 428b, 428c and 428d may have the same angular position about driveshaft 12 so as to be generally adjacent one another, but radially spaced apart from one another in the same plane extending radially from driveshaft 12. While only two sets of cam pairs are illustrated, any number of sets of cam pairs may be utilized, each set with a different diameter, thereby allowing the density of power generation assemblies 402 about driveshaft 12 to be increased. It will be appreciated that the greater number of power generation assemblies about driveshaft 12, the greater the power generation capacity of linear electric device 10. Thus, the foregoing arrangement allows greater alternator power output than would a traditional electrical alternator. Similar to FIG.13a in FIG.13b, a linear electric device 10 (of FIG.1) is illustrated as linear electric device 500, wherein two or more power generation assemblies 502 are positioned to be parallel with driveshaft 12 but at different diameters about driveshaft 12 to permit a desired level of power generation from linear electric device 10 across a range of RPM input speeds of the driveshaft 12 from an external source (not shown), such as from an internal combustion engine, wind turbine, water turbine or other rotary drive equipment. In the illustrated embodiment, three such power generation assemblies 502a, 502b, 502c are shown, each associated with a cam 518a, 518b, 518c mounted on driveshaft 12. While in FIG 13a each power generation assembly is described as being positioned between a pair of cams 418 (see FIG. 13a), as previously described in other embodiments, a power generation assembly need only have a single magnet assembly reciprocating in a coil assembly. Thus, shown in FIG.14b is a driveshaft 12 extending along a driveshaft axis 14. Mounted along driveshaft 12 between driveshaft ends 512 and 513, in spaced apart relationship to one another, are at first, second and third harmonic cams 518a, 518b and 518c. Cam 518a has a first cam diameter D ₁ (defined as R1*2); cam 518b has a second cam diameter D ₂ (defined as R ₂ *2) that is greater than the first cam diameter D ₁ ; and cam 518c has a third cam diameter D ₃ (defined as R ₃ *2) that is greater than the second cam diameter D _2. In some embodiments, power generation assemblies 502a, 502b 502c may have the same angular position about driveshaft 12 so as to be generally adjacent one another, but radially spaced apart from one another in the same plane extending radially from driveshaft 12, while in other embodiments, power generation assemblies 502a, 502b, 502c may have different angular positions about driveshaft 12. More specifically, power generation assembly 502a is comprised of a first magnet assembly 522a which magnet assembly 522a is axially aligned within a stator cylinder assembly 524a disposed along a coil assembly axis 25a. Stator cylinder assembly 524a is formed of a stator cylinder 560a extending between a first end 562a and a second end 564a with windings 568a disposed along stator cylinder 560a. Coil assembly axis 25a is spaced apart from, but generally parallel with, driveshaft axis 14 of driveshaft 12. Magnet assembly 522a includes a cam follower assembly 526a attached to a magnet slide arm 528a to which is mounted a magnet 530a. Cam follower assembly 526a includes a first engagement mechanism 586a and a second engagement mechanism 587a and straddles cam 518a so as to be engaged by engagement mechanism s 586a, 587a. Cam follower assembly 526a is attached to and acts upon magnet slide arm 528a which carries magnet 530a. At least one set of windings 568a along stator cylinder 560a generally define a magnet slide chamber 532a within and through which magnet 530a can translate. Power generation assembly 502b likewise is comprised of a second magnet assembly 522b axially aligned within a stator cylinder assembly 524b disposed along a coil assembly axis 25b. Stator cylinder assembly 524b is formed of a stator cylinder 560b extending between a first end 562b and a second end 564b and windings 568b disposed along stator cylinder 560b. Coil assembly axis 25b is spaced apart from, but generally parallel with, driveshaft axis 14 of driveshaft 12. Magnet assembly 522b includes a cam follower assembly 526b attached to a magnet slide arm 528b to which is mounted a magnet 530b. Cam follower assembly 526b includes a first engagement mechanism 586b and a second engagement mechanism 587b and straddles cam 518b so as to be engaged by engagement mechanism 586b, 587b, which are shown as rollers in this embodiment. Cam follower assembly 526b is attached to and acts upon magnet slide arm 528b which carries a magnet 530b. At least one set of windings 568b along stator cylinder 560b generally define a magnet slide chamber 532b within and through which magnet 530b can translate. Power generation assembly 502c likewise is comprised of a third magnet assembly 522c axially aligned within a stator cylinder assembly 524c disposed along a coil assembly axis 25c. Stator cylinder assembly 524c is formed of a stator cylinder 560c extending between a first end 562c and a second end 564c and windings 568c disposed along stator cylinder 560c. Coil assembly axis 25c is spaced apart from, but generally parallel with, driveshaft axis 14 of driveshaft 12. Magnet assembly 522c includes a cam follower assembly 526c attached to a magnet slide arm 528c to which is mounted a magnet 530c. Cam follower assembly 526c includes a first engagement mechanism 586c and a second engagement mechanism 587c and straddles cam 518c so as to be engaged by engagement mechanism s 586c, 587c, which are shown as rollers in this embodiment. Cam follower assembly 526c is attached to and acts upon magnet slide arm 528c which carries a magnet 530c. At least one set of windings 568c along stator cylinder 560c generally define a magnet slide chamber 532c within and through which magnet 530c can translate. Stator cylinder 560a associated with power generation assembly 502a is spaced apart from driveshaft 12 at a first radius R ₁ , stator cylinder 560b associated with power generation assembly 502b is spaced apart from driveshaft 12 at a second radius R ₂ , and stator cylinder 560c associated with power generation assembly 502c is spaced apart from driveshaft 12 at a second radius R ₃ , where the second radius R ₂ is greater than the first radius R ₁ and the third radius R3 is greater than the second radius R ₂ . In some embodiments, therefore, a plurality of first stator cylinders 560a may be spaced about driveshaft 12 at the first radius R ₁ ; a plurality of second stator cylinders 560b may be spaced about driveshaft 12 at the second radius R ₂ ; and a plurality of third stator cylinders 560c may be spaced about driveshaft 12 at the second radius R ₃ . In one or more embodiments, magnet slide arm 528a has a first length L1, magnet slide arm 528b has a second length L2 and magnet slide arm 528c has a third length, where L3 is longer than L2, which is longer than L1. In this regard, the lengths of the shafts 104 (see FIG.3) of the various magnet slide arm 528 may be adjusted as desired for the appropriate magnet slide length L. Each cam follower assembly 526a, 526b, 526c straddles its respective cam 518a, 518b, 518c and is movable with respect to its respective cam 518a, 518b, 518c so that radial rotation of the respective cams 518a, 518b, 518c resulting from rotation of driveshaft 12 can translate into axial movement of magnet slide arms 528a, 528b, 528c within their respective stator cylinder assemblies 524a, 524b, 524c. In one or more embodiments, each cam 518 further includes a circumferential shoulder 538 extending around the cylindrical periphery of a cam hub 536. Shoulder 538 is generally curvilinear in shape and can be characterized as having a certain frequency, where the frequency may generally refer to the number of occurrences of repeating peaks and troughs about the 360-degree circumference of the circumferential shoulder 538. In some embodiments, the curvilinear shape of shoulder 538a of the first cam 518a is of a first frequency and the curvilinear shape of shoulder 538b of the second cam 518b is of a second frequency, which in some embodiments may differ from the first frequency, permitting different power generation assemblies 502 to have different electrical and/or waveform outputs. Likewise, the curvilinear shape of shoulder 538c of the third cam 518c is of a third frequency which may differ from the first and second frequencies. In some embodiments, it may be desirable for the magnet assemblies 522a, 522b and 522c to translate in unison. In such case, the third frequency is less than the second frequency which is less than the first frequency. In other embodiments, it may be desirable for magnet assembly 522c to translate more rapidly than magnet assembly 522b and for magnet assembly 522b to translate more rapidly than magnet assembly 522a, in which case, the third frequency may be equal to or greater than the second frequency which may be equal to or greater than the first frequency. Thus, different electrical and/or waveform outputs can be achieved as desired without altering the rotational speed of driveshaft 12. Similarly, in one or more embodiments, the amplitude of the curvilinear shoulders 538 of each cam 518a, 518b and 518c are the same, with the depth of the troughs and the height of the peaks being substantially equal, while in other embodiments, the depth of the troughs may differ from height of the peaks, permitting different power generation assemblies 502 to have different electrical and/or waveform outputs. In some embodiments, the amplitude of the second and third cams 518b, 518c, respectively is less than the amplitude of the first cam 518a, as well as from one another, in order to adjust timing of the respective power generation assemblies 502b, 502c. Because cam 518a has a different diameter D ₁ than the diameter D ₂ of cams 518b, 518c, shoulder 538 of the respective cams 518a, 518b, 518c are at different diameters. As such, power generation assemblies 502a, 502b, 502c may have the same angular position about driveshaft 12 so as to be generally adjacent one another, but radially spaced apart from one another in the same plane extending radially from driveshaft 12. While only three sets of cam pairs are illustrated, any number of sets of cam pairs may be utilized, each set with a different diameter D, thereby allowing the density of power generation assemblies 502 about driveshaft 12 to be increased. It will be appreciated that the greater number of power generation assemblies 502 about driveshaft 12, the greater the power generation capacity of linear electric device 10. Thus, the foregoing arrangement allows greater alternator power output than would a traditional electrical alternator. Turning to FIG.14, linear electric device 300 is illustrated, where one or more cams 318, such as spaced apart cams 318a and 318b, are radially adjustable relative to driveshaft 312 utilizing a radial adjustment mechanism 304. Specifically, in FIG.14, a simplified longitudinal section and cutaway view of a linear electric device 300 is shown, where driveshaft 312 extends along a primary axis 314 and passes axially through the center of the linear electric device 300. Driveshaft 312 is supported by a pair of bearings 316a, 316b in a fixed axial position. Positioned along driveshaft 312 in spaced apart relationship to one another are harmonic cams 318a, 318b. A power generation assembly 302a comprises a first magnet assembly 322a and a second magnet assembly 322b which magnet assemblies 322a, 322b are axially aligned with one another within a stator cylinder assembly 324 disposed along a coil assembly axis 325. Coil assembly axis 325 is spaced apart from but generally parallel with primary axis 314 of driveshaft 312. Each magnet assembly 322 generally includes a cam follower assembly 326 attached to a magnet slide 328 to which is mounted a magnet 330. Each cam follower assembly 326 straddles its respective cam 318 and moves magnet 330 by virtue of magnet slide 328. Stator cylinder assembly 324 generally includes a stator cylinder 329 along which windings 327 are disposed. Opposed magnet slides 328 within cylinder assembly 324 generally define a magnet slide chamber 332 that allows the magnet slides to pass though the windings 327 in order to generate electric power. Rotation of the driveshaft 312 from an external source (not shown) such as an internal combustion engine, wind turbine, water turbine or other rotary power source results in rotation of cams 318a, 318b, which in turn causes magnet slides 328 to reciprocate though magnet slide chamber 332 along coil assembly axis 325, all as generally described above with respect to other embodiments. In the illustrated embodiment, linear electric device 300 further includes a second power generation assembly 302b symmetrically positioned relative to power generation 302a. Driveshaft 312 is further characterized by a first end 346 and a second end 348. Axially formed in at least one end of driveshaft 312 is a first axially extending hydraulic passage 350 and a second axially extending hydraulic passage 352, such as shown at first end 346. In the illustrated embodiment, second end 348 likewise has a first axially extending hydraulic passage 354 and a second axially extending hydraulic passage 356. A first radial passage 358 in fluid communication with the first hydraulic passage 350 is formed in driveshaft 312 and terminates at an outlet 360. Likewise, a second radial passage 362 in fluid communication with the second hydraulic passage 352 is formed in driveshaft 312 and terminates at an outlet 364. Formed along driveshaft 312 is first collar 366 and second collar 368, each extending radially outward from driveshaft 312. In one embodiment, collars 366, 368 are spaced apart from one another along driveshaft 312. Collars 366, 368 may be integrally formed as part of driveshaft 312 or separately formed. Cam 318 is mounted on driveshaft 312 adjacent outlets 360, 364 and collars 366, 368. In particular, cam 318 includes a hub 336 having a first end 337 mounted relative to first collar 366 so as to form a first pressure chamber 370 therebetween, with outlet 360 in fluid communication with first pressure chamber 370. Likewise, hub 336 has a second end 339 mounted relative to second collar 368 so as to form a second pressure chamber 372 therebetween, with outlet 364 in fluid communication with second pressure chamber 372. Radial adjustment mechanism 304 may include a hydraulic fluid source 313a in fluid communication with each of hydraulic passage 350 and hydraulic passage 352 to alternatively supply pressurized fluid (not shown) to one or the other of first pressure chamber 370 or second pressure chamber 372. In this regard, radial adjustment mechanism 304 may further include a controller 309 to control delivery of fluid from fluid source 313 to the pressure chambers 370, 372. In this regard, controller 309 may receive data from one or more sensors 311 about a condition of linear electric device 300, such as the rotational speed of cam 318 (sensor 311a) or shape of waveform being generated (sensor 311b) or the power output (sensor 311c), and control delivery of fluid from fluid source 313 in order to optimize the position of cam 318 relative to driveshaft 312 for a particular purpose. For example, it has been found that cam 318 may be in a first radial orientation relative to driveshaft 312 when a first waveform shape is desired from linear electric device 300 and cam 318 may be in a second radial orientation (different than the first radial orientation) relative to driveshaft 312 when a second waveform shape is desired from linear electric device 300. Persons of ordinary skill in the art will appreciate that application of a pressurized fluid to first pressure chamber 370 will result in radial rotation of cam 318 in a first direction relative to driveshaft 312 and application of a pressurized fluid (not shown) to second pressure chamber 372 will result in radial rotation of cam 318 in a second direction relative to driveshaft 312. Moreover, the relative pressures of the pressurized fluids in each of the chambers 370, 372 may be adjusted to adjust the radial orientation of cam 318 on driveshaft 12, as described above. It will also be appreciated that the foregoing is particularly desirable because changes to the relative position of cam 318 may be made dynamically in real time while linear electric device 300 is in operation. These changes may be based on monitoring of various operational parameters and/or conditions of linear electric device 300 with one or more sensors 315 in real time. Thus, in some embodiments, based on measurements from sensor 315, hydraulic fluid source 313 may be operated to rotate cam 318 in a first direction or a second direction relative to driveshaft 312 in order to achieve a desired output from a power generation assembly 302. Alternatively, the system may be static by maintaining the relative fluid pressure in each chamber at the same pressure. Turning to FIGS.15 and 16, cam 318 is shown with another embodiment of radial adjustment mechanism 304. Specifically, in this embodiment, driveshaft 312 includes a first lug 380 and second lug 382, each extending radially outward from driveshaft 312. In one embodiment, lugs 380, 382 opposed one another about driveshaft 312. Lugs 380, 382 may be integrally formed as part of driveshaft 312, as shown, or separately formed. Driveshaft 312 further includes a first axially extending hydraulic passage 350 and a second axially extending hydraulic passage 352, preferably of varied axial lengths. A first set of radial passages 384a, 384b is in fluid communication with the first axially extending hydraulic passage 350, each of the radial passages 384a, 384b formed in a lug 380, 382, respectively, and terminates at a ported lug outlet 385a, 385b. Likewise, a second set of radial passages 386a, 386b (shown in dashed), preferably spaced apart axially from the first set of radial passages 384a, 384b, is in fluid communication with the second axially extending hydraulic passage 352. Each of the radial passages 386a, 386b is formed in a lug 380, 382, respectively, and terminates at a ported lug outlet 387a, 387b. Cam 318 is mounted on driveshaft 312 adjacent outlets 385, 387 and lugs 380, 382. In particular, cam 318 includes a hub 388 having a hub wall 389 with a curvilinear shoulder 390 extending radially outward from the outer circumference of hub wall 389. In some embodiments, as illustrated, shoulder 390 may be shaped to have two peaks with a corresponding number of troughs, such that the cam profiles describe two complete cycles per revolution and are thus double harmonics, while in other embodiments, shoulder 390 may have other number of peaks and troughs, as desired. Formed along the inner circumference of hub wall 389 are first and second spaced apart slots 392a, 392b, each slot 392a, 392b disposed to receive a lug 380, 382, respectively. In one or more embodiments, the slots 392a, 392b may oppose one another. First slot 392a is characterized by a first shoulder 391a and a second shoulder 393a, while second slot 392b is characterized by a third shoulder 391b and a fourth shoulder 393b. In particular, lug 380 extends into first slot 392a to form a first pressure chamber 394a between lug 380 and a first slot shoulder 391a, with outlet 385a in fluid communication with first pressure chamber 394a. Likewise, lug 382 extends into second slot 392b to form a third pressure chamber 394b between lug 382 and a third slot shoulder 391b, with outlet 385b in fluid communication with third pressure chamber 394b. In one or more embodiments, such as the illustrated embodiments, a second pressure chamber 395a is formed between lug 380 and a second slot shoulder 393a, with outlet 387a in fluid communication with second pressure chamber 395a. Likewise, a fourth pressure chamber 395b is formed between lug 382 and a fourth slot shoulder 393b, with outlet 387b in fluid communication with fourth pressure chamber 395b. It will be appreciated that in some embodiments, pressure chambers 394b and 395b, as well as passages 384b and 386b and outlets 385b and 387b can be eliminated, with only a pressure chamber 394a utilized as a first pressure chamber to rotate cam 318 in a first direction relative to driveshaft 312, and only a pressure chamber 395a utilized as a second pressure chamber to rotate cam 318 in a second opposite direction relative to driveshaft 312. Moreover, during operation of linear electric device 300 employing the radial adjustment mechanism 304, pressurized fluid can be alternatingly supplied to chamber 394a or chamber 395a to dynamically adjust the radial position of cam 318 relative to driveshaft 312 as desired, rotating cam 318 either in a first clockwise direction or a second counterclockwise direction about driveshaft 312. In one or more embodiments, power generation assemblies 20 can be engaged and disengaged from the driveshaft 12 as power requirements for electric device 10 change. This is particularly true where different sets of power generation assemblies 20 are connected to different sets of cams 18, such as is the case in FIGS.13a and 13b. During start-up or when the electric device is subjected to heavy loads, both all of the power generation assemblies 20 can be used to provide power to driveshaft 12. Where power requirements are lower, electric device 10 can operate only with a portion of the power generation assemblies 20. For example, electric device 400 shows power generation assembly 402a engaging cams 418a, 418b, while power generation assembly 402b engaging cams 418c, 418d. Likewise, electric device 500 shows power generation assembly 502a engaging cam 518a, power generation assembly 502b engaging cam 518b and power generation assembly 502c engaging cam 518c. In each case, electric device 10, 400, 500, as the case may be, may include a clutch (not shown) to engage and disengage power generation assemblies 20, 402, 502 from driveshaft 12. In one or more embodiments, one or more cams 18, 418, 518 may include a clutch (not shown) that engages and disengages cams 18, 418, 518 from driveshaft 12. Such a clutch man be mechanically operated, hydraulically operated, electrically operated or operated in any other way generally known in the industry. In one or more embodiments, cams 18, 418, 518 may be rotated to engage and disengage the driveshaft 12 utilizing the radial adjustment mechanism 304 illustrated in FIGS. 14, 15 and 16, whereby rotation of cams 318 in a first direction couples cams 318 to driveshaft 312 and rotation in a second direction, opposite the first direction, decouples cams 318 from driveshaft 312. It will be appreciated that in each of the embodiments of an electric device 10 described above, the electric device 10 may be utilized as a linear electric alternator to generate electricity in the form of an electrical output or alternatively, as an electric motor to driveshaft 12. In the former case, electrical terminal 27 may be utilized to direct electrical power generated in windings 68 (and 70) away from linear electric alternator 10 via leads 29 as an electrical output, whereas in the latter case, electrical terminal 27 may be used to supply electricity to windings 68 (and 70) via leads 29 as an electrical input in order to energize windings 68 (and 70). In such case, the energized electromagnetic windings or coils may be utilized to urge magnet slide arm 28 to move axially within stator cylinder 60. In one or more embodiments, the electrical input is an alternating electric current. Turning to FIG. 17 another embodiment of electric device 400 is illustrated wherein two harmonic cams 418a, 418b are shown spaced apart along a driveshaft 412 which extends along a driveshaft axis 414 with an electric power assembly 415 disposed along driveshaft 412 between the two cams 418a, 418b and with at least one electric power assembly 420 positioned radially outward from driveshaft 412 and electric power assembly 415. As such, electric power assembly 415 is coupled to the driveshaft and functions as an axial electric power assembly or a driveshaft electric power assembly, as distinguished from the radial electric power assemblies positioned radially outward from driveshaft 412 and coupled to cams. In the illustrated embodiment, six power generation assemblies 420 are shown spaced symmetrically about driveshaft 412 so as to be spaced from one another and driveshaft 412. Each power generation assembly 420 includes a stator cylinder assembly 424 and at least one magnet assembly 422 which may be configured in some embodiments as generally described above with respect to FIGS. 1-16. In one or more embodiments, each power generation assembly 420 has a first magnet assembly 422a and a second magnet assembly 422b which magnet assemblies 422a, 422b are axially aligned with one another within stator cylinder assembly 424 disposed along a coil assembly axis 425. Coil assembly axis 425 is spaced apart from but generally parallel with driveshaft axis 414 of driveshaft 412. Each magnet assembly 422 generally includes a cam follower assembly 426 attached to a magnet slide arm (not shown) to which is mounted a magnet 430. The opposed magnet slide arms of a power generation assembly 420 are adapted to reciprocate in opposite directions along coil assembly axis 425. Each cam follower assembly 426 straddles a corresponding cam 418 and acts to move a magnet 430 through its associated magnet slide arm (not shown) within a stator cylinder assembly 424 as generally described above. In the embodiment of FIG. 17, disposed along driveshaft 412 adjacent harmonic cams 418a, 418b is a driveshaft electric power assembly 415. In this embodiment, driveshaft electric power assembly 415 is positioned between harmonic cams 418a, 418b and radially inward of power generation assemblies 420, and generally includes a stator assembly 417 and a rotor assembly 419. In or more embodiments, a plurality of power generation assemblies 420 are positioned around driveshaft 412 at a first radius and the driveshaft electric power assembly 415 is characterized by an outer radius that is less than the first radius such that the driveshaft electric power assembly 412 is positioned radially inward of the power generation assemblies 420. Although not limited to a particular configuration in electric device 400 other than being positioned along driveshaft 412 between harmonic cams 418a, 418b, in one or more embodiments, driveshaft electric power assembly 415 is coaxial with driveshaft 412, with a rotor assembly 419 mounted on driveshaft 412 and a stator assembly 417 spaced radially outward from stator assembly 417 in the general arrangement of a radial flux electric motor. In other embodiments, driveshaft electric power assembly 415 may be an axial flux electric motor, in which case rotor assembly 419 and stator assembly 417 are spaced apart from one another axially along driveshaft 412. FIGS. 18 and 19 better illustrated the positioning of driveshaft electric power assembly 415 along driveshaft 412 adjacent harmonic cams 418a, 418b. In these figures, rotor assembly 419 is shown mounted on driveshaft 412 between harmonic cams 418a, 418b. In this particular embodiment, driveshaft 412 is shown as hollow, although it need not be. As will be appreciated, stator assembly 417 and rotor assembly 419 are not limited to a particular configuration. In one or more embodiments, rotor assembly 419 may include one or more windings or coils, while in other embodiments, rotor assembly 419 may include one or more permanent magnets. Spaced radially outward from rotor assembly 419 is one or more stator assemblies 417, which in some embodiments may consist of electromagnetic windings or coils 469 while in other embodiments may consist of one or more permanent magnets (not shown). Stator assembly 417 may generally be mounted within an electric motor housing or frame (not shown) as is well known in the art. As a non-liming example, stator assembly 417 may be supported by support block, such as enclosure 53 described above, that also supports first magnet assembly 422a, second magnet assembly 422b and stator cylinder assembly 424 of the power generation assemblies 420. It will be appreciated that one of the benefits of the above-described electric device 400 is that electric power assemblies 420 may be utilized to enhance the torque output of electric device 400 and driveshaft electric power assembly 415 may be utilized to enhance the speed output of electric device 400. In other words, electric power assemblies 420 may be utilized to provide torque to driveshaft 412, while driveshaft electric power assembly 415 may be utilized to provide speed to driveshaft 412. For example, during start-up, electric power assemblies 420 may be actuated to provide torque to driveshaft 412 through harmonic cams 418a, 418b, while driveshaft electric power assembly 415 may be utilized during on-going operation of driveshaft 412. In this regard, electric device 400 may include one or more clutches (not shown) to engage and disengage radial electric power assemblies 420 or axial electric power assembly 415 from driveshaft 412. Such a clutch may be mechanically operated, hydraulically operated, electrically operated or operated in any other way generally known in the industry. In one or more embodiments, harmonic cams 418a, 418b may include a clutch (not shown) that engages and disengages cams 418a, 418b from driveshaft 412. In one or more embodiments, cams 418a, 418b may be rotated to engage and/or disengage the driveshaft 12 (and hence, radial electric power assemblies 420) utilizing the radial adjustment mechanism 304 illustrated in FIGS.14 -16, whereby rotation of cams 418 in a first direction couples cams 418 to driveshaft 412 and rotation in a second direction, opposite the first direction, decouples cams 418 from driveshaft 412. Likewise, a clutch (not shown) disposed along driveshaft 12 between cams 418a, 418b may be utilized to engage and/or disengage driveshaft electric power assembly 415 from driveshaft 12. In this regard, one or more of the controller 111, power source 109 and inverter 108 such as described above in FIGS.6 may be utilized to selectively operate power generation assemblies 420 and driveshaft electric power assembly 415 based on the output requirements of electric device 400 during a particular stage of operation. In this regard, controller 111 may be used to dynamically switch back and forth between power generation assemblies 420 and driveshaft electric power assembly 415, or may be used to operate both power generation assemblies 420 and driveshaft electric power assembly 415, again, depending on the output requirements of electric device 400 during a particular stage of operation. The electrical inverter 108 may be electrically connected to a power source 109 via electrical leads 29, which may also interconnect electrical inverter 108 to driveshaft electric power assembly 415 to convert alternating current generated by stator assembly 417 into direct current that can be stored by power source 109 or alternatively, to supply power to stator assembly 417. In other embodiments, electrical inverter 108 may be eliminated. In one or more embodiments, one benefit of the above descried electric device 10 operating as an electric motor is that the electric device can be used to alter or adjust the output RPM of the driveshaft 12 without the need for a variable frequency drive. Rather, various electromagnetic windings or coils associated with various cams may be selectively energized to produce different RMPs on driveshaft 12, particularly where the coil density among the windings differ. Thus, for example, a first set of electromagnetic windings or coils associated with a first stator cylinder and a first cam with a first number of lobes may be energized to drive the driveshaft at a first RPM speed. Thereafter, to a second set of electromagnetic windings or coils associated with a second stator cylinder and a second cam with a second number of lobes different than the first number of lobes may be energized to drive the driveshaft at a second RPM speed different than the first RPM speed. In one or more embodiments, the second cam has more lobes than the first cam, resulting in an increase in the output RPMs of the driveshaft, whereby the second RPM speed is greater than the first RPM speed. In such embodiments, opposing cams in an electric motor may be selected to have different frequencies. Moreover, in some embodiments, an electric device 10 having multiple cams 18 mounted on driveshaft 12 may be particularly suited for such adjustability. In this same vein, by adjusting the number of cams, the shape and number of cam lobes, the diameter of the cams and the arrangement of the magnetic slides relative to one another, such an electric motor can achieve significantly greater output and torque than traditional electric motors. In addition to being readily controlled to alter power output, an additional benefit of the electric devices described herein is their capability of easily controlling the waveform of the power output. An additional benefit of the electric devices described herein is that they are readily scalable for large scale power generation. Thus, an electric device has been described.
