Jack Durban's Account: Device is Real; Steven Mark wasn't

On March 16, 2008, Jack Durban wrote:

A little background on who I am and why I remained silent for over a decade.

I have been an avid inventor and product developer since I was a kid. I was drawing detailed engines and mechanisms by age 9 and just had a knack for looking at a product and finding faults in the design. In school I spent all my time drawing machines and basic circuits. I worked on my first patent in High school and it issued in 1977. Since then I have developed over 200 products that cover several industries. I currently hold 21 patents that have issued or are pending published applications. As a product developer I have prepared dozens of patents for clients and read thousands of patents during searches over a quarter century now. I have seen it all when it comes to technology and I have an open mind which is rare in my field. I have designed and worked on alternative health devices like the RIFE machines and even worked with Barry Lynes the author of "The Cancer cure that worked". I designed the world's first Brainwave analyzer to measure correlates of I.Q. with Dr. John Ertl a brilliant PhD in Cybernetics. I am putting this out there to say that I have always entered into any design or design evaluation task with eyes wide open and no preconceptions.

The reason why I didn't come forward sooner was due to an NDA [Non-Disclosure Agreement] I signed back in '96. As one who makes a living working with invention, patents and is a caretaker of others intellectual property, I have to be very careful in discussing anything of a sensitive nature. Although all NDA's have to expire by a certain date, I waited an extra 8 years just in case Steven ever surfaced again.

I have seen several so called free energy devices, and all without exception were failures. Not all were fraudulent. Some were just not well understood by their creators as not meeting the requirements of producing over unity power or work.

When I was approached by M.M. to work with Steven Marks, I wasn't overly excited after years of seeing these all crash and burn, but I was again all ears. When I saw the devices work and was able to rotate the units 90 degrees without loss of output power, I felt a chill go over me like seeing a ghost. You see I know Tesla's works as he is one of my heroes like Edison and others. I fully understood the impact of being able to rotate the device without performance depredation. The gyroscopic sensation felt when moving the device made it clear to me instantly that the coils displaced about the perimeter of the device were switching in a quadrature fashion like stators in a motor yet there were no mechanical devices in the unit. It became clear that there was a lot of current flowing from winding to winding.

The device worked and the video is real. It was shot at a mansion that Steven rented in Lemon Heights California. Steven's face does not appear in the first videos but I did notice that he does appear in the one on youtube that shows potential investors. He always wore an all black suit and shoes even when doing basic lab work. It was part of the facade.

The sad thing is that Steven was a bit of a hustler. He received millions from several investors, and never delivered the end product. Steven spent wildly on a lavish lifestyle. The seemingly sophisticated test equipment one sees in the videos was in fact a collection of audio and video gear. It was all purchased for audio development on Steven's so called 3D audio theater system that was shown at CES in 1996 or 97.

I have no doubt that Steven was not the true inventor of this device, as he was not technically savvy enough for such a feat. His only technical background was working on televisions and cars. He claimed to be an expert in Rolls Royce repair and he did own an older model but it wasn't anything outstanding.

I met Steven in 1996 when my company was hired by Mercury Marilla, Steven's boyfriend at the time, to replicate the device's capabilities by any means possible. At first I thought he was trying to find out if there was another quick way to produce the same result with an alternative approach, but I later realized he was likely looking for a second design that he could pawn off on investors so he could retain the original design.

There were many, many investors pouring in money like there was no tomorrow in the hopes of getting their hands on what appeared to be the holy grail of free energy.

There was a reason beyond the endless supply of investment dollars that kept the technology from ever being delivered, and that was the fact that the device only ran for so long before it shut down due to overheating, which averaged 20 minutes or so after it was activated. He was very frustrated with the thermal issues, but every time I came up with a solution he would say he would check it out, but nothing ever came of the remedies. He would never allow me to take the unit apart or do any dissecting at all. The design was quite simple. There were two sets of windings arranged in a fashion that very closely resemble the Tesla patent 381,970 circa 1888. There were two large chokes and polypropylene caps that appeared to be an output smoothing function. My Instincts told me that the choke and cap pair was a tuned tank, but knowing how little electronics knowledge Steven had, I could not see him being capable of doing any tank tuning, and there was no grid dip gear around. I'll be releasing more information as I get time.

Oh one little side note among many in this interesting moment in time was Steven’s use of a magnet to activate the device. This was just a ruse. The magnet, a cheap Radio Shack magnet at that was deployed only as a means of closing a simple Reed switch that closed the primary circuit. Steven thought this would throw off those who viewed live demos, as he was well aware that many potential investors were bringing their top engineers with them.

I am thinking about writing a screenplay on this, as there is much, much more to the story, including sex, crimes and misdemeanors. I have been sitting on this story for over a decade now.

Coming Forward After All This Time

Hello Sterling,

The post was at… Link here

A purely random pick after days with little sleep. For some odd reason I just thought it was time to tell the story that few have ever heard. Perhaps it was seeing all the pretenders making up stuff about the man and the machine only to profit themselves from the legacy.

I did secretly release some secrets to Keely net a few years ago and they agreed to keep my name a secret.

Now after 11 years I no longer am concerned about breeching anyone’s confidence. NDA’s only last so long!

I hope you have an open mind as the technology did indeed work.

As one who was often hired to debunk so called over unity devices I was very fortunate to play with the device and work on a couple projects with Steven both power and audio related.

I should tell you in advance that I have a pretty good idea as to how it worked but I do not know enough to build it without spending some serious time in the lab which. Post-Interview Comment

I would like to add the following...

This was part of an email of 20 March 08, between myself and one of the respected elders in the movement to reproduce the SM Device. This email is redacted and only shows one question of many and my position on Steven Mark to clarify my motives in this matter.

Let’s examine this situation.

1. If there ever was a man deserving of some knocking it is Steven Mark. I understand that you guys are walking on egg shells with this guy with the hopes that he will someday reveal the final formula; but there is little reason to believe beyond hope and despair that he ever will reveal the final answer.

2. Megalomaniacs like Steven need an audience to feed their narcissistic appetite. To give anyone the final keys to making the device work would be cutting the umbilical cord to his adoring fans. All he could gain from such an act is a thank you. Remember, Steven knows how to make these already. If he wanted to help you or anyone else he could have without hesitation long ago.

3. There are several others doing this and are well beyond where Steven is. Once he realizes this watch how quickly he comes forward to help when his obsolescence becomes a self realization and his fan base loses interest.

The reason I came forth yesterday was to tell the truth about what I experienced while working with Steven Mark. Contrary to some of the less than friendly posts regarding my inability to shed any light any light on the technology beyond what is already known, I never represented that I possessed or would reveal anything of a technical nature that would further any development underway. If I had I certainly would have finished the device myself.

What was a payoff? None for myself. Most of the feedback I received publicly was negative. The only payoff I can hope for is that if a guy like Steven Mark, a hustler and tinkerer with less than extraordinary intellect was able to reproduce this free energy device there is hope for others to replicate this device also as many others have to date.

I apologize for offending those who are still drinking the Steven Mark Koolaid but I don’t think most of you know of or appreciate the trail of shattered dreams and victims left in this mans’ wake.

All the Best,

Steven Marks TPU Patent Found

Solid State Electric Generator

Inventor : Graham Alan Gunderson

A solid-state electrical generator including at least one permanent magnet, magnetically coupled to a ferromagnetic core provided with at least one hole penetrating its volume; the hole(s) and magnet(s) being placed such that the hole(s) penetrating the ferromagnetic core's volume intercept flux from the permanent magnet(s) coupled into the ferromagnetic core. A first wire coil is wound around the ferromagnetic core for the purpose of moving the coupled permanent magnet flux within the ferromagnetic core. A second wire is routed through the hole(s) penetrating the volume of the ferromagnetic core, for the purpose of intercepting this moving magnetic flux, thereby inducing an output electromotive force.; A changing voltage applied to the first wire coil causes coupled permanent magnet flux to move within the core relative to the hole(s) penetrating the core volume, thus inducing electromotive force along wire(s) passing through the hole(s) in the ferromagnetic core. The mechanical action of an electrical generator is thereby synthesized without use of moving parts.

[0001] This application claims priority to Provisional Application 60/645,674 filed Jan. 21, 2005, entitled PERMANENT MAGNET DRIVEN ELECTRIC GENERATOR.


[0002] 1. Field of the Invention

[0003] This invention relates to a method and device for generating electrical power using solid state means.

[0004] 2. Description of the Related Art

[0005] It has long been known that moving a magnetic field across a wire will generate an electromotive force (EMF), or voltage, along the wire. When this wire is connected in an electrical closed circuit, in order to perform work, an electric current is driven through this closed circuit by the induced electromotive force.

[0006] It has also long been known that this resulting electric current causes the closed circuit to become encircled with a secondary, induced magnetic field, whose polarity opposes the primary magnetic field that first induced the EMF. This magnetic opposition creates mutual repulsion as a moving magnet moves toward such a closed circuit and attraction as that moving magnet then moves away from the closed circuit. Both these actions tend to slow, or "drag" the progress of the moving magnet generating the EMF, causing the electric generator to act as a magnetic brake, in direct proportion to the amount of electric current produced.

[0007] Gas engines, hydroelectric dams and steam-fed turbines have historically been used to overcome this magnetic braking action occurring within mechanical electric generators. A large amount of mechanical power is ultimately required to produce a large amount of electrical power, since the magnetic braking interaction resulting from induced electrical current is generally proportional to the amount of power being generated.

[0008] There has been a long felt need for a generator which reduces or eliminates this well-known magnetic braking interaction, while nevertheless generating useful electric power. The need for convenient, economical, and powerful sources of renewable energy remains urgent. When the magnetic fields within a generator are caused to move and interact by means other than applied mechanical force, electric power can be supplied without the necessity of consuming limited natural resources, thus with far greater economy.


[0009] It has long been known that the source of the magnetism within a permanent magnet is a spinning electric current within ferromagnetic atoms of certain elements, persisting indefinitely in accord with well-defined quantum rules. This atomic current encircles each atom, thereby causing each atom to emit a magnetic field, as a miniature electromagnet.

[0010] This atomic current does not exist in magnets alone. It also exists in ordinary metallic iron, and in any element or metallic alloy that can be "magnetized", that is, exhibits ferromagnetism. All ferromagnetic atoms and "magnetic metals" contain such quantum atomic electromagnets.

[0011] In specific ferromagnetic materials, the orientation axis of each atomic electromagnet is flexible. The orientation of magnetic flux within, as well as external to the material, easily pivots. Such materials are referred to as magnetically "soft", due to this magnetic flexibility.

[0012] Permanent magnet materials are magnetically "hard". The orientation axis of each atomic electromagnet is fixed in place within a rigid crystal structure. The total magnetic field produced by these atoms cannot easily move. This constraint permanently aligns the field of ordinary magnets, hence the name "permanent".

[0013] The axis of circular current flow in one ferromagnetic atom can direct the axis of magnetism within another ferromagnetic atom, through a process known as spin exchange. This gives a soft magnetic material, like raw iron, the useful ability to aim, focus, and redirect the magnetic field emitted from a magnetically hard permanent magnet.

[0014] In the present invention, a permanent magnet's rigid field is sent into a magnetically flexible, "soft" magnetic material. The permanent magnet's apparent location, observed from points within the magnetically soft material, will effectively move, vibrate, and appear to shift position when the magnetization of the soft magnetic material is modulated by ancillary means (much like the sun, viewed while underwater, appears to move when the water is agitated). By this mechanism, the motion required for generation of electricity can be synthesized within a soft ferromagnetic material, without requiring physical movement or an applied mechanical force.

[0015] The present invention synthesizes virtual motion of magnets and their magnetic fields, producing an electrical generator described herein, which does not require mechanical action or moving parts. The present invention describes an electrical generator wherein magnetic braking phenomena, known as expressions of Lenz's Law, do not oppose the means by which the magnetic field energy is caused to move. The synthesized magnetic motion thereby manifests without mechanical or electrical resistance. This synthesized magnetic motion is aided by forces generated in accordance with Lenz's Law, in order to produce acceleration of the synthesized magnetic motion, instead of physical "magnetic braking" common to mechanically-actuated electrical generators. Because of this novel magnetic interaction, the solid-state static generator of the present invention is a robust generator, requiring only a small electric force to operate.


[0016] So that the above-recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to various embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.

[0017] FIG. 1 is an exploded view of the generator of this invention.

[0018] FIG. 2 is a cross sectional elevation of the generator of this invention.

[0019] FIG. 3 is a schematic diagram of the magnetic action occurring within the generator of FIGS. 1 and 2.

[0020] FIG. 4 is a circuit diagram, illustrating one method of electrically operating the generator of this invention.


[0021] FIG. 1 depicts a partially exploded view of an embodiment of an electric generator of this invention. The parts have been numbered, with the numbering convention applied to FIGS. 1, 2, and 3.

[0022] Numeral 1 represents a permanent magnet with its North pole pointing inward toward the soft ferromagnetic core of the device. Similarly, numeral 2 indicates permanent magnets of preferably the same shape and composition, with their South poles aimed inward toward the opposite side, or opposite surface of the device. The letters "S" and "N" denote these respective magnetic poles in the drawing. Other magnetic polarities and configurations may be used with success; the pattern shown merely illustrative of one efficient mode of adding magnets to the core.

[0023] The magnets may be formed of any polarized magnetic material. In order of descending effectiveness, the most desirable permanent-magnet materials are Neodymium-Iron-Boron (NIB) magnets, Samarium Cobalt magnets, AlNiCo alloy magnets, or "ceramic" strontium-, barium- or lead-ferrite magnets. A primary factor determining permanent magnet material composition is the magnetic flux strength of the particular material type. In an embodiment of the invention, these magnets may also be substituted with one or more electromagnets producing the required magnetic flux. In another embodiment of the invention, a superimposed DC current bias can be applied to the output wire to generate the required magnetic flux, in substitution of, or in conjunction with said permanent magnets.

[0024] Numeral 3 indicates the magnetic core. This core is a critical member of the generator, determining the characteristics of output power capacity, optimal magnet type, electrical impedance, and operating frequency range. This core may be any shape, composed of any ferromagnetic substance, formed by any process (sintering, casting, adhesive bonding, tape winding, etc). A wide spectrum of geometries, materials, and processes are known in the art of magnetic cores. Effective common materials include, but are not limited to, amorphous metal alloys (such as that sold under the trademark designation "Metglas" by Metglas Inc., Conway S.C.), nanocrystalline alloys, manganese and zinc ferrites as well as ferrites of any suitable element including any combination of magnetically "hard" and "soft" ferrites, powdered metals and ferromagnetic alloys, laminations of cobalt and/or iron, and silicon-iron "electrical steel". This invention successfully utilizes any ferromagnetic material, while functioning as claimed. In an embodiment of the invention, and for the purpose of illustration, a circular "toroid" core is illustrated. In an embodiment of the invention, the composition may be bonded iron powder, commonly available from many manufacturers.

[0025] Regardless of core type, the core is prepared with holes, through which wires may pass, which have been drilled or formed to penetrate the core's ferromagnetic volume. The toroidal core 3 shown includes radial holes pointing toward a common center. If, for example stiff wire rods were to be inserted through each of these holes, these wires would meet at the center point of the core, producing an appearance similar to a spoke wheel. If a square or rectangular core (not illustrated) is used instead, these holes are preferably oriented parallel to the core's flat sides, causing stiff rods passed through the holes to form a square grid pattern, as the rods cross each other in the interior "window" area framed by the core. While in other embodiments of the invention, these holes may take any possible orientation or patterns of orientation within the scope of the present generator, a simple row of radial holes is illustrated herein as one example.

[0026] Numeral 4 depicts a wire or bundle of wires, i.e. output wire 4, that pick-up and carry the generator's output power. Typically this wire is composed of insulated copper, though other output mediums such as aluminum, iron, dielectric material, polymers, and semiconducting materials may be substituted. It may be seen in FIG. 1 and FIG. 2 that wire 4, which serves as an output medium, passes alternately through neighboring holes formed in core 3. The path taken by wire 4 undulates, passing in an opposite direction through each adjacent hole. If an even number of holes is used, the wire will emerge on the same side of the core it first entered on, once all holes are filled. The resulting pair of trailing leads may be twisted together or similarly terminated, forming the output terminals of the generator shown at Numeral 5. Output wire 4 may also make multiple passes through each hole in the core. Though the winding pattern is not necessarily undulatory; this basic form is shown by way of example. Many effective connection styles exist; this illustration shows the simplest. All successful connection methods pass wire 4 at some point through the holes in the core.

[0027] Numeral 6 in FIGS. 1, 2, and 3 points to a partial illustration of the input winding, or inductive coil used to shift the permanent magnets' fields within the core. Typically, this wire coil encircles the core, wrapping around it. For the toroidal core presented, input coil 6 resembles the outer windings of a typical toroidal inductor, a common electrical component. For the sake of clarity, only a few turns of coil 6 are shown in each of drawing FIGS. 1, 2, and 3. In practice, this coil may cover the entire core, or specific sections of the core, including or not including the magnets, while remaining within scope of the present invention.

[0028] FIG. 2 shows the same representative generator of FIG. 1, looking transparently "down" through it from above, so the relative positions of the core holes (dotted lines), the path of the output wire, and magnet positions (as shaded areas) are made clear.

[0029] The generator shown uses a core with 8 radially drilled holes. The spacing between these illustrative holes is equal. As shown, each hole is displaced 45 degrees from the next. All holes' centers lay along a common plane; this imaginary plane is centered half-way along the core's vertical thickness. Cores of any shape and size may include as few as two, or as many as hundreds of holes, and a similar number of magnets. Other variations exist, such as generators with multiple rows of holes, zigzag and diagonal patterns, or output wire 4 molded directly into the core material. In any case, the basic magnetic interaction shown in FIG. 3 occurs for each hole in the core, as detailed below.

[0030] FIG. 3 shows the same design, viewed broadside. The curvature of the core has been flattened to the page for the purpose of illustration. The magnets are represented schematically, protruding from core top and bottom, with arrows indicating the direction of magnetic flux-arrow heads pointing north, tails south.

[0031] In practice, the free, unattached polar ends of the generator's magnets may be left as-is, in open air, or provided with a common ferromagnetic path linking unused North and South poles together, as a magnetic "ground". This common return path is typically made of steel, iron or similar material, taking the form of a ferrous enclosure housing the device. It may serve the additional purpose of a protecting chassis. The magnetic return may also be another ferromagnetic core in repetition of the present invention, forming a stack or layered series of generators, sharing common magnets between generator cores. Any such additions are without direct bearing on the functional principle of the generator itself, and have therefore been omitted from these illustrations.

[0032] Two example flux diagrams are given in FIG. 3. Each example is shown in a space between schematically depicted partial input coils 6. A positive or negative polarity marker indicates the direction of input current, applied through the input coil. This applied current produces "modulating" magnetic flux, which is used to synthesize motion of the permanent magnets, and is shown as a double-tailed horizontal arrow (a) along the core 3. Each example shows this double-tailed arrow (a) pointing to the right or the left depending on the polarity of applied current.

[0033] In either case, vertical flux entering the core (b, 3) from the external permanent magnets (1, 2) is swept along, within the core, by the direction of the double-tailed arrow representing the input coil's magnetic flux (a). These curved arrows (b) in the space between the magnets and holes can be seen to shift or bend (a->b), as if they were streams or jets of air subject to a changing wind (a).

[0034] The resulting sweeping motion of the permanent magnets' fields causes their flux (b) to brush back and forth over the holes and wire 4 passing through these holes. Just as in a mechanical generator, when magnetic flux brushes or "cuts" sideways across a conductor in this way, EMF or voltage is induced. By connecting an electrical load across the ends of this wire conductor (Numeral 5, in FIGS. 1, 2) a current is allowed to flow through the load in a closed circuit, delivering electrical power able to perform work. Input of an alternating current across the input coil 6 generates an alternating magnetic field (a) causing the fields of permanent magnets 1, and 2 to shift (b) within the core 3, inducing electrical power through a load (attached to terminals 5), as if the fixed magnets (1,2) themselves were physically moving. However, no mechanical motion is present.

[0035] In a mechanical generator, induced current powering an electrical load returns back through output wire 4 creating a secondary induced magnetic field, exerting forces which substantially oppose the original magnetic field inducing the original EMF. Since load currents induce their own, secondary magnetic fields opposing the original act of induction in this way, the source of the original induction requires additional energy to restore itself and continue generating electricity. In mechanical generators, the energy-inducing motion of the generator's magnetic fields is being physically actuated, requiring a strong prime mover (such as a steam turbine) to restore the EMF-generating magnetic fields' motion, against the braking effect of the output-induced magnetic fields (the induced field (c), and the inducing field (b)), destructively in mutual opposition. It is this inductive opposition which ultimately must be overcome by physical force, which is commonly produced by consumption of other energy resources.

[0036] The electric generator of the present invention is not actuated by mechanical force. The generator of the present invention also makes use of the induced, secondary magnetic field in such a way as to not cause opposition, but instead addition, and resulting acceleration of magnetic field motion. Because the present invention is not mechanically actuated, and because the magnetic fields do not act to destroy one another in mutual opposition, the present invention does not require consumption of natural resources in order to generate electricity.

[0037] The present generator's induced magnetic field, resulting from electric current flowing through the load and returning through output wire 4, is that of a closed loop encircling each hole in the core admitting the output conductor or conductive medium (4, c). The present generator's induced magnetic fields create magnetic flux in the form of closed loops within the ferromagnetic core. The magnetic field "encircles" each hole in the core carrying output wire 4, similar to the threads of a screw "encircling" the shaft of the screw.

[0038] Within this generator, the magnetic field from output medium or wire 4 immediately encircles each hole formed in the core (c) carrying this medium or wire 4. Since wire 4 may take an opposing direction through each neighboring hole, the direction of the resulting magnetic field will likewise be opposite. The directions of arrows (b) and (c) are, at each hole, opposing, headed in opposite directions, since (b) is the inducing flux and (c) is the induced flux, each opposing one another while generating electricity.

[0039] However, this magnetic opposition is effectively directed against the permanent magnets that are injecting their flux into the core, but not the source of the alternating magnetic input field 6. In the present solid state generator, induced output flux (4, c) is directed to oppose the permanent magnets (1, 2) not the input flux source (6, a) that is synthesizing the virtual motion of those magnets (1, 2) by its magnetizing action on core 3.

[0040] The present generator employs magnets as the source of motive pressure driving the generator, since they are the entity being opposed or "pushed against" by the opposing reaction induced by output current which is powering a load. Experiments show that high-quality permanent magnets can be magnetically "pushed against" in this way for very long periods of time, before becoming demagnetized or "spent".

[0041] FIG. 3 illustrates inducing representative flux arrows (b) directed oppositely against induced representative flux (c). In materials typically used to form core 3, fields flowing in mutually opposite directions tend to cancel each other, just as positive and negative numbers of equal magnitude sum to zero.

[0042] On the remaining side of each hole, opposite the permanent magnet, no mutual opposition takes place. Induced flux (c) caused by the generator load currents remains present; however, inducing flux from the permanent magnets (b) is not present since no magnet is present, on this side, to source the necessary flux. This leaves the induced flux (c) encircling the hole, as well as input flux (a) from the input coils 6, continuing its path along the core, on either side of each hole.

[0043] On the side of each core hole where a magnet is present, action (b) and reaction (c) magnetic flux substantially cancel and annihilate, being oppositely directed within the core. On the other side of each hole, where no magnet is present, input flux (a) and reaction flux (c) share a common direction. Magnetic flux thereby adds together in these zones, where induced magnetic flux (c) aids the input flux (a). This is the reverse of typical generator action, where induced flux (c) is typically opposing the "input" flux originating the induction.

[0044] Since the magnetic interaction herein is a combination of magnetic flux opposition and magnetic flux acceleration, there is no longer an overall magnetic braking, or total opposition effect. The braking and opposition is counterbalanced by a simultaneous magnetic acceleration within the core. Since mechanical motion is absent, the equivalent electrical effect ranges from idling, or absence of opposition, to a strengthening and overall acceleration of the electrical input signal (within coils 6). Proper selection of the permanent magnet (1, 2) material and flux density, core 3 material magnetic characteristics, core hole pattern and spacing, and output medium connection technique create embodiments wherein the present generator will display an absence of electrical loading at the input and/or an overall amplification of the input signal. This ultimately causes less input energy to be required in order to work the generator. Therefore, as increasing amounts of energy are withdrawn from the generator as output power performing useful work, decreasing amounts of energy are generally required to operate it. This process endures, working against the permanent magnets (1, 2) until they are demagnetized.

[0045] In an embodiment of this invention, FIG. 4 illustrates a typical operating circuit employing the generator of this invention. A square-wave input signal, furnished by appropriate transistorized switching means, is applied at the input terminals (S), to the primary (a) of a step-down transformer 11. The secondary winding (b) of the input transformer may be a single turn, in series with a capacitor 12 and the generator 13 input coil (c), forming a series resonant circuit. The frequency of the applied square wave (S) must either match, or be an integral sub-harmonic of the resonant frequency of this 3-element transformer-capacitor-inductor input circuit.

[0046] Generator 13 output winding (d) is connected to resistive load L through switch 14. When switch 14 is closed, generated power is dissipated at L, which is any resistive load, for example, an incandescent lamp or resistive heater.

[0047] Once input resonance is achieved, and the square wave input frequency applied at S is such that the combined reactive impedance of total inductance (b+c) is equal in magnitude to the opposing reactive impedance of capacitance 12, the electrical phases of current through, and voltage across, generator 13 input coil (c) will flow 90 degrees apart in resonant quadrature. Power drawn from the square wave input-energy source applying power to S will now be at a minimum.

[0048] In this condition, the resonant energy present at the generator input may be measured by connecting a voltage probe across the test points (v), situated across the generator input coil, together with a current probe around point (i), situated in series with the generator input coil (c). The instantaneous vector product of these two measurements indicates the energy circulating at the generator's input, ultimately shifting the permanent magnets' fields in order to create useful induction. This situation persists until the magnets are no longer magnetized.

[0049] It will be apparent to those skilled in the art that a square (or other) wave may be applied directly to the generator input terminals (c) without use of other components. While this remains effective, advantageous re-generating effects may not be realized to their fullest extent with such direct excitation. Use of a resonant circuit, particularly with inclusion of a capacitor 12 as suggested, facilitates recirculation of energy within the input circuit, generally producing efficient excitation and a reduction of required input power as loads are applied.
