An ECAT circuit variation with a large air core coil in the background


Shown on this page are some of the first ECAT circuits I built in 1993-1994 while on the team of the Advanced Technology Group. The circuits consisted of air core coils varying in size and winding configuration. The underlying ECAT theory was to use cross phasing of various frequencies in such a way as to produce a virtual energy pump thereby providing an anomalous power gain within the circuit.

From 1993 through the first half of 1996, hundreds of coils and winding designs were tried. For the most part the work was empirical in its beginning stages, little substantiated science was available from which to base my work.

Various researchers in the so-called Free Energy1 area have focused on various configurations of pulse capture circuits where the back EMF of an inductor was thought in some way to capture energy from the ether and add it back into the circuit, thereby presenting gain. As with any free-minded group the Fee Energy folks seemed totally against ever duplicating in detail a particular circuit offering by me, and for whatever reason used modified designs or components hoping there magic was just as powerful as the original experimenter. This resulted in many Internet published attempts at duplicating one or more of the ECAT circuits and of course leading to total failure by those trying.

One design that was an off shoot of the initial ECAT research (although never acknowledged as such) was the TEP2 or the 'Time Energy Pump'. The TEP design was in its own right a good look into the possibility of using solid state devices in a closed loop, yet it fell short of sustained usable excess energy.

Another researcher that worked with TEP designs can be found at CTG Labs3.

There is one so-called acid test proposed by those wishing to suppress certain research, using applied terms such as 'Over Unity', a condition where (Output/Input or (COP4) > 1). This proclaimed test states that such a device must self-run, producing an unlimited source of power without any external input energy. This proposed test is totally a diversion from the truth and is proposed as a way for energy utilities, suppliers and regulators to hide or otherwise discredit valid research in this area.

Let me try to explain in somewhat simple terms what the last paragraph is really about and why I can show that the so-called acid test is invalid. You need to form a mental picture of two areas separated by an infinite wall and a large door between the two areas. On the other side of the door is endless potential energy in the form of a high-speed wind. On your side you have a wind generator just waiting for a wind to begin providing you with electricity. All that is needed is to open the door and allow the wind to drive your wind generator and you have an endless supply of electricity. So far it seems simple enough, just push the door open, get the generator working and use some of the produced electricity in a device to keep the door open. It won't work this way and I hope I can present a clear picture of just why it will not.

ECAT depends on what I call 'Poly-Phasing', the capturing external (virtual) energy during a critical phase of the trigger pulse.

The following picture is of the  large air core power coil with inner load coil. A neon bulb held within the power coil will indicate a high voltage electric field. If one were to replace the power coil and the load coil with similar transformer configuration on a conventional core, this ECAT design would not show the effect of external energy capture.


So what is Polyphasing? Another example is in order, assume you are standing on a crowed street corner in New York City, where the ambient noise would be defining, yet you would be able to hear and identify individual sounds at different sound levels (pressures) and frequencies. The sound you hear is a mix of all audible sounds around you, some weak, some normal and some extreme in loudness. If you could in some way selectively pick certain sounds and properly phase them, you could arrive at a sound pressure greater than any one of the individual sounds. This is ECAT, it coheres the energy around it in such a way that it can be absorbed by its air core coil, resulting in an overall increase in kinetic energy.

The basic ECAT circuit with the polyphasing transformer which is the center point this ECAT design


This ECAT design is operated at a respectable frequency of 4.3Khz, the trigger frequency and resulting sub frequency on which the power harmonics are developed. The polyphasing transformer is of a Theta core design and is made from a material that saturates at a desired saturation point. The space between the power coil and the load coil is the area from which the additional energy is absorbed.

This ECAT circuit is initialized with a 12V DC supply, either battery or some form of converter. The driver pulse 50% duty cycle supplied from a conventional generator or solid state multi-vibrator and drives a single MOSFET transistor.

The test points are indicated in the upper left corner of each image






Conventional electronic engineering considers spurious phenomenon an unwanted artifact and uses various methods of filtration and feedback to cancel and remove such phenomenon. By today's standards this ECAT circuit is considered to be a very poorly designed switching circuit.

In my initial ECAT work, when transformers were changed from air core to core material (ferrite's or metallic) the potential for seeing anomalous power gains disappeared, until the following design was developed.

After considerable work with the new ECAT design a workable unit was designed that drives a 120V @12W lamp bulb. The matching transformer used to interface to the 120 volt bulb is a standard 60hz design and suffers considerable loss when running under the high frequency of ECAT. This transformer loss will be eliminated with a proper high frequency design, but currently the 60Hz form wastes some 6 watts of the total input power of 8.25 watts.

This ECAT variation has an input power of 8.25 watts and supplies 12 watts to the light bulb as shown and suffers a loss in the conversion transformer of some 6 watts. Therefore the total power produced by this ECAT is 18.11 watts for an input of 8.25 watts. The power gain is therefore 18.11 / 8.25 =  2.194

The following picture show this ECAT in operation.

The next photo shows ECAT and its 12 watt ligh bulb before power is applied.

The next photo is another closeup of ECAT driving the 12 watt lamp.

In the preceding photo, notice the strange light at the bottom of the bulbs filament. This light is from high voltage arcing at the base of the bulb.

The input power rails are stabilized with both 0.01uf ceramic capacitors along the rails and one very large 2kuf capacitor to insure the voltage does not contain low ripple or high frequency components.

Considerable design information was obtained during tests arriving at this point in ECAT history. The following scope photos show what is seen at the switching MOSFET drain during the OFF cycle of the pulsed operation. As can be seen, the excess energy capture occurs during the OFF period of the MOSFET.

In earlier ECAT designs (top of page) one can see that a large heat sink was used on the MOSFET driver, while in this design one can see that the heat sink has been drastically reduced in size and is only required should the load be disconnected from the circuit. During a load condition the quiescent current is only 90ma, yet if the load is mismatched, the current can go well over 1amp and the MOSFET begins to heat. Under normal operation the MOSFET and its heat sink is cool (not cold like the transformer) but cool.

With addition of an HF matching transformer the following scope photo is what is seen on the secondary of this matching transformer.  As can be seen the secondary voltage is quite high and the pulse shape is more uniform than with the older 60Hz transformer.
