Simple Working Overunity Device!

Sorry but I'm not following... may be missing something here...

you're pumping 30V pulses into a coil at freqs over 1.7MHz,
and getting out 1V AC at what freq?
In any case, it sounds like you're getting 1V that pulses the LED... If you would connect 2 LEDs, one p-n and the other n-p, to the same
wire terminals of the secondary, you would rectify the AC and the LEDs would blink in turn, wouldn't they?
But still, if we're measuring 1V AC and that is powering the LEDs,
would you not be much better off pumping your 30V pulses directly into the LED?

Seems to me you're still using quite a lot of power to get out very little...

I'm not sending in 30V pulses.  I'm sending in about 1.5V pulses, and the resonance of the first coil is changing this into a 30V sine wave.

The sine wave is somehow induced in the second coil, but due to losses of transmission it is reduced to about 1V.  The frequency on the second coil matches the frequency on the first coil.

The LEDs should blink in turn, yes, but I wouldn't really be able to see it blinking.  It is blinking on and off 1.7 million times per second.

I'm really learning a lot through this experiment.  I'm a senior in Electrical Engineering and they just don't teach us about this RF stuff at my university.

You see, I told you I wasn't following

Yeah weird eh, I also noticed that my university electrodynamics books said very little on RF and related stuff...
I was lucky enough to find an old 1950s textbook on radio waves and transmission circuits, which helped me out a lot back in the day.
But it would be nice if they'd teach this in high schools or college... seems to me you've missed something if you don't know at least some about it...

anyways, how much are you getting out extra compared to your input?
You said a little but how much is that?

what happens if you connect the aluminum core to the signal ground of the freq gen, but still keep the circuit open?

I got 1 VAC out, with about a -5 mV DC bias.  And enough current to light the LED.  I haven't measure the input or output power, if that's what you're asking for.

I did try grounding the core when I was first trying to resonate the primary coil by itself.  That didn't seem to have any noticeable effect though.  I was also checking for any kind of significant voltage developed on the core (for TPU application), but was unable to get anything more than some weak noisy signal.

I don't think I mentioned this yet, but the reason I set this thing up was to try to recreate the MIT "WiTricity" effect.  It was only when I saw the huge gain on the primary coil that I thought "hmm...overunity?".

"magnetically coupled resonance"

"WiTricity" is 40% efficient and directional - doesn't sound very good.

I believe Tesla worked with this at one point and considered it worthless since it was electromagnetic.
