The TPU uncovered? (A PROBABLE technique.)

Actually, that is my POS "el cheapo" FG... Around $120 brand new on ebay. Sine out is great, sawtooth not bad, but the squares are smoothed a little too much (rounded one corner)

It is a Victor VC2002 up to 2mhz @ 10v max.

My good FG is a BK 3025 up to 5mhz @ 15v max. (nice clean waveforms)

My scope is a BK 1590A 100mhz 4-channel

@EM

Good observation. Another is on the video DVD I got from JDO. When he states "DC at 5Khz with hash", someone quickly states something to the effect "not AC?", and he quickly replies "YES IT IS AC, but for all intents and purposes it is DC." Check it out, you will see what I am talking about. The one I originally watched on google video was too cruddy to catch this, or else I just plain missed it.

The first scope shot is a nice oscillating kick. 

The second looks to be a resonating kick.

To think I had always relegated scopes of these as "transformer action", then wrote them off whenever found, and in many cases tried to clear the signal so I could look for "kicks". UGGGGGGHHHH!

Someone check my logic please.

Say I have four controls, each 1/4 of the circumference of my TPU.

1. I mix three seperate truly resonant square wave frequencies
2. pass them into the first Control through a hf blocking diode.
3. the signal then comes out of the first control, and I pass it into a seperate inductor to phase it.
4. I then pass this into the second control
5. I repeat step 3 into another inductor to phase it yet again.
6. I pass this into the third control
7. I repeat step 3 to phase it again
8. I pass this into the fourth control.
9. I pass this through a hf blocking diode back into the first control. (It should be in phase now if I remember correctly.)

Would this work? If so, then this would be a simple design three oscillator one signal generated rotating field. Three signals designed specifically for summing for increased power. (W/ coinciding rise fall of previous description.)

If so, then the mid frequency could be found with a nine-volt, just as EM did in his post. Scope the output, calculate the natural resonant frequency based upon duration of harmonics in the shot, then both divide and multiply by three.  Or divide by three twice, and use this as the high frequency. Should be pretty simple.

EM, you just posted the simplest means I know to find the natural resonant frequency of the coil I can think of! Good job! That sure beats scoping around with the FG process I have been doing! That should work with any coil system!

no one has come forward and explained Paul's experiment as of today.

SM told us the kicks are overunity and that they are current kicks. the voltage kicks we see in Paul's scope shots are not overunity. they are a basic electrical reaction due to Lenz's law.

all things being ideal, the voltage kicks seen in Paul's post would have been closer to the 20V level, not 12V.

they are higher than the applied voltage--why?

because of Lenz's law, the inductor will produce a counter emf, and it is this cemf that we see as the 12V spikes.

the two concentric pancake coils is more complicated than it needs to be. wind a simple single air core inductor (solenoid) to give you about the same inductance as your pancake coil (about 20uH) and pulse it the same way. you'll get almost the same scope shot, with no ringing or resonance. the spikes will be there, both negative and positive as before.

every piece of wire no matter how long has some inductance, and every device that will drive this piece of wire has a finite output impedance (50 Ohm typical for function generators, and the crirical missing element in duff's model), so in theory it should be possible to produce these voltage kicks on demand. in fact in practice, it should be impossible to get rid of them.

so at the end of the day, what do we have? we have some transient cemf produced that exceeds the applied input voltage level, but current does not increase nor does the power, leaving us with exactly what we put in, minus some natural losses.

but we still don't have the kicks SM talked about, because the above kicks are not increases in current, and they aren't overunity.

so until now the peanut gallery has been mostly quiet about this. forgive me for breaking my promise of keeping quiet

Now,when you're talking about it I think I may have something interesting. Mistakenly I modified my Bedini monopole simplified in such way that it became self-oscillating. I can light a NE-2 neon placed instead of charging battery. The voltage here is mostly at power source level but there are one or two sweet spots of POT when voltage rises up to 50V. I placed a 10uF/250V capacitor at the output connected with the neon. Interesting and curious effect - light spectrum changed from red-purplish to pure orange on both neons (second one is normally in that circuit). Unfortunately I didn't tested it longer then a second or two because charging that cap to 250V or up with such high frequency oscillation is a matter of 1 second or even faster. I have no oscilloscope, sorry.Two analog ammeters would be also good (one on power supply and one between neon and cap). I don't state it's OU, just cannot check. :-(

Maybe help me improve this circuit, I'm a little scared of possible capacitor explosion due to overvoltage.

The kick is at the top of the bell curve edge hidden in the ringing. The next pulse in amplifies it. Unfortunately the DC part also causes its demise. The ringing in the DC part is the 2 forces fighting for control. The DC wins as shown by the stability of the voltage.
