Bifilar pancake coil overunity experiment

No they don't even try to understand that  P = V * I .

OK, so here are a couple more scopeshots. I made sure I was isolated and only the scope probe references are connected to the "ground" point on the circuit. Can't show the raw FG signal now but that's not a problem. That got rid of the DC offset on CH1 that I was seeing (a simple error of reference on my part, sorry). And of course now connecting/disconnecting the coil makes more of a difference. But I still see the amplified and inverted signal on CH2 that is very different from yours.

"They" understand that for an equation to yield valid results, the values that populate the variables must also be valid.

If you pull your V and I values out of your ... er.... random circuit somewhere, different branches.... well we've seen that kind of thing before and it didn't work then either.

At least I am willing and able to reexamine my results and correct them if necessary. Are you?

They don't understand that the relations between values must be right and they must have right meanings.

P = V * I

That is weirdo, this doesn't look like coil at all, ch1 should go up when the pulse starts with coil. I don't understand what it is at all, a coil with only back-emf, that would be an absolute overunity hehe.

OK, finally I am able to get something like the scope traces you showed. By inverting CH2 at the scope and by ditching the coax coil and substituting one of my own true Tesla Bifilar coils which has 685 microHenry of inductance, I get these traces.

Now.... I definitely am driving the transistor with a 20 percent high duty cycle. Are you quite sure your setup does 20 percent high and not 80 percent high? Or perhaps you've inverted your CH2 on your scope?
