Bifilar pancake coil overunity experiment

[TinselKoala]

OK, so the previous results were using my TBF coil. Here's one using the coax bifi. It has a lot less inductance so I went up in frequency to 110 kHz for this test. Note that the integral across two cycles is _decreasing_ overall, which means the scope sees the negative portion of the trace as being greater in area than the positive portion of the trace.

Does this now mean OU?

With these the result was the following.

Now these input and output powers, are the input and output powers of the coil. The input power of the coil is the power dissipated in the resistance of the coil as heat, and the power stored in the coil. The output power is also less by the power dissipated in the resistance of the coil.

These are the real powers consumed by the coil and generated by the coil, they have a real physical meaning, these are not arbitrary or fictional values.

The jury is still out on that one. I'm not convinced that these measurements actually equate to actual input and output power of the total circuit, which is what actually matters.

Can you measure the static resistance of your coil, so i can calculate the powers actually stored and generated by the induction in the coil?

The DC resistance of the TBF coil used is 3.90 ohms.

No, these measurements don't equate to the actual input and output power of the total circuit. These are the input and output powers of the coil. Because what interests what concerns the research, is the induction in the coil, not the whole circuit.

The DC resistance of the TBF coil used is 3.90 ohms.

The dissipation in the resistance of the coil is relatively small, the results were the following.

Input power was 8.838 uW
Input induction power was 8.837 uW
Output power was 7.202 uW
Output induction power was 7.203 uW

Now you are facing the issue of false precision. Your results cannot be more precise than the _least_ precise number that goes into the calculations.

Yes, and i made the area of the ch2 input part slightly larger, this is the least precise, and this also changes the final result the most. Yet, if it were the actual size, the input power were slightly lower, but there still were no overunity.
