Mysterious Resonant Circuit

@ Vortex1 

Excellent test. Thanks. But EM was getting approximately 17 volts across his 150 ohm 1/4 resistor. In your chart, 190F is only 11 volts.So it would seem that you are not getting as much output voltage as he was (and therefore not as much power). Would you agree with that?

Oh stupid me. He was getting 17 volts peak. That would be about 12 volts RMS. But still higher than 11 volts.

xee

The 11 volts does not represent output of my coil, rather it is a static test of 75 mA DC through the 150 ohm resistor from my DC current source. In this case it produced 190 F heating, which resistor can now be connected to coil to see if heating effect is greater or smaller. This was reference information.

How do you go from 17 volts peak to 12 volts RMS. This is not possible except with simple rules, which do not hold for irregular waveforms and are therefore highly inaccurate with high crest ratios.

Perhaps I was not clear......V

@ Vortex1,
You are probaby correct. Afterall, it is theoretically impossible to get more power out than goes in. You seem to have provided a good method of testing EMDevices results. But his sine waves looked good after he added additional RF traps.

EDIT: I guess this is a good example of how hard it is to tell how perfect a sine wave is just by looking at it.

Hi xee

I do not rule out that something interesting could be happening with EM's coil. I am just interested in getting precise power measurements, which is difficult considering crest factors. My RF powermeters do not have enough resolution or accuracy for this low power level, I cannot rely on scope waveforms unless the scope has very wide bandwith. Even then crest factors must be considered.

Please check wikipedia for a quick overview of measurement when crest factors are involved.

I do wish EM the best and hope his circuit does produce OU.

ART

As is well known, and documented, there is such a thing as "Cold"
electricty.

How do you know the device is producing "cold electricity" if it cannot be measured?
Show me a documented device that produces "cold electricity" that anyone can replicate.
Supply a circuit that truly delivers "cold electricity" and I will come up with a way to measure it.

Kind regards......V
