A quote from Nelso Rocha's last message to me:

About your test i'm glad that you could duplicate yourself the " apparently "magnetic field exclusion with your new configuration ;) nice ! Hope you explore this theme and see if that  are only made by high frequency , or something more happen ;)  like stack other pancake coil and look to that like one capacitor exchanging charges between each plate  (two pancake coils ) .

Been working on this base platform circuit Nelson Rocha published.  He indicates this is an excellent starting point for researching radiant energy transfer.  Once better understood, it should be possible to loop this circuit with minimal modifications.


The Toroid, is connected like a joule thief. D2 C3 C4 and R1 are fine tuning the timing of the oscillation of the toroid.
The tip122 (q1) opens en closes, S1 of T2 to ground. basically pulsing the transformer. output on p1 and p2 on T2 is back emf, when q1 closes.

If we now connect p1 and p2 of T2  to a bifilar coil.... bingo.

But... i like to use the resonant frequency, which is much higher than this circuit. But if I look at the coils of Nelson, those resonant frequencies would be a lot higher. Maybe he has tuned down the resonant frequency, by adding capacitance... or he simply doesn't use the resonant frequency

I tried tuning down the resonant frequency, by adding parallel capacitance to the bifilar coil. And it works. tuned it down from 600KHz to 125kHz by adding a 10nF cap. So the coils can be tuned low enough for this pulse generator.

The toroid (determines the frequency), for use of the joule thief, could also be a bifilar coil (i just love them). T2 is a step up transformer. making the pulses into the kV range.

It works.
I made a joule thief with a bifilar coil, a mpsa13 darlington npn and a 10k tunable resistor. It resonated at around 44kHz, showing sharp pulses. (dc input was 1,5V 0,3A)


Then I hooked up a self made (so it could handle the high freq) pulse step up transformer between the positive and the collector.
The secondary now showed simultaneous pulses on its ends, opposite phase. around 300V Perfect!

I made the pulse step up transformer, using a radio frequency ferrite rod, with a single wire tight winding( 1 layer) around it as the secondary, taped it, and wound the primary, as a bifilar winding(. with much spacing (less windings). also one layer

Im so happy it works. I have been searching for this. :D

Next step, is hooking up the bigger flat pancake bifilar coil, and tuning it down, so the pulses match the resonant frequency.

OK, the pulses where there but it didnt work out with the bifilar pancake coil hooked up. I guess the impedances where off. I will leave this alone for now.

oh man just when you think you got something...  BAM... something like impedance kicks you.

you will get there. nice work!

Thanks Russ,
It was a bit disappointing, but I also expected it. I made the joule thief bifilar coil, on top of the secondary single wire coil, that stepped up the voltgage of the pulses. The scope signal was promising, but the power was absent.

 I also tested it with the step up tranformer in between the collector and positive, as in Nelson Rocha's design. And it does work.
Just not like I need it (would need to rebuild coils... )

If one observes closely, Nelson's basic exciter circuit with the addition of a boost transistor is supplying the radiant energy to the pancake coil set.  From there it gets a little tricky to figure out where things go.

This image gives a pretty clear view of his pancake coil set.  Notice the blue wires appear to be the typical single stack Tesla bifilar pancake coils.  I think these coils are for capturing the radiant energy.  The outer white and clear audio cable coils are a little different.  They look to be side-by-side bifilar--interesting concept I hadn't considered before.  Not sure how the behavior differs between the two coil styles, but it's certainly worth investigating.  One has to presume if the geometry is different, electrically they will be different as well.  I would suspect this design focuses the energy towards the blue coils that actually captures the radiant energy instead of blasting it into space radially away from the outer perimeter of the exciter coils.

What needs to be seriously considered in this image is that Nelson is showing us everything that is necessary for a true self-running, free energy device.  It's right there in plain view if we can come to understand how and why it works as he has demonstrated.

I've wondered about that also.
he uses speaker wire,  and the outside coils seem parallel wound, so not like tesla,  1 layer of 2 wires,  but two layers of parallel wires(series connected) . i tried this and it works.

so maybe,  the blue middle coil,  is 1 coil.
consisting of 2 parallel windings (but series connected like tesla)
the capacitance, dielectric field,  crosses over the white dielectric material, in the center.

I can't remember if the phases are opposite at the wire endings. (resonating at res freq)

it would need HV to act as capacitor plates. to bridge the white dielectric.

What I'm getting at by mentioning the two "styles" of bifilar pancake coils is purely a spatial relationship.  Remember, dielectricity acts within a surface, magnetism acts within a volume.  So of the two styles, one is probably preferable for the exciter and the other for the collector/accumulator.  We can talk about bypassing Lenz Law here, because my hunch is the BEMF from the load will not in any way effect the source.  I think Nelson made that clear here when he passed the strong magnet over the coil and it did nothing to the source input power, or the load for that matter.

Keep in mind in this test Nelson wasn't using his radiant driver.  I think he was just proving the behavior of the side-by-side coils.

I've been studying Nelson's videos and had another look at his radiant box.  I think I'm starting to better understand how he got this to work.

Plenty of juice to fire-up that big shop lamp.


My take on things:

The white side-by-side bifilar coil on the left is being energized with/by the high-output board with the fan & heatsink.  This provides the amps.  Not certain what kind of a signal this is, but suspect it is quite similar to an induction cooker.

The board on the right with the yellow-taped transformer is likely the radiant exciter, the output of which probably goes to the blue bifilar coils.  This provides the voltage.

The clear side-by-side bifilar coil on the right is most likely the output coil.  The entire coil stack is what one might classify as a mixer.  This is where volts X amps is happening.  The spacing between the two blue coils gooped with silicone likely sets up the proper phase angle so the voltage and amperage signals can mix in-phase into usable output power.

The board on the bottom left could be a separate exciter that drives one of the blue coils, or it could just be the rest of the primary exciter--not really sure as yet.  Maybe it synchronizes the frequency of the exciter with the high-output board.  Based on it's placement, this makes the most sense.

What I am feeling pretty confident about is the mixing concept here.  From watching the videos Nelson has published and seeing the timeline of his development, this concept seems the most likely.  Even Nelson's learning circuit had two outputs--high and low voltage, which makes me think he was considering joining these outputs back together at some point in the future.  That is something he has successfully done with his pancake coil stack.  Sure looks to me like a very logical and well thought out progression that has led to a successful self-running device.  In the video above, the universal power supply is only there for testing purposes; it's quite obvious the 24 volt output from this power supply could be looped back in place of the benchtop supply he uses to start the device.  This is identical to how the Ruslan device was looped and I know Nelson spent quite a bit of time on that thread at overunity.com--it's a very practical solution that he would implement.

To be honest, I'm not seeing anything in Nelson's radiant box that I would call magical.  Everything has a purpose.  What I think he discovered how to do is mix volts and amps to get true usable power and it looks like pancake coils is the most straightforward way to accomplish this task.

or he simply doesn't use the resonant frequency
That's my guess at the moment.  He just uses the radiant spikes (unipolar) to charge the dielectric between the two bifilar coils.  The high-power driver that creates the magnetic frequency pushes the charge built up between the two bifilar coils into the output coil.  When that happens you get amps from the driver and the volts from the dielectric and there's your over unity.

Found something interesting in Nelson's training circuit...

Connected as Nelson shows in bucking style configuration, if pulsed with DC, there's an interesting back swing not obvious just looking at a voltage or current signal, but when you turn on the math trace and calculate watts, you can clearly see the reverse power spike.  Pretty sharp too, less than 200ns at its zero crossing.
