Captret

Browsed around on JLN Labs page yesterday evening and found ibpointless2's Captret:

I was amazed. Basically the simplest zero-point energy generator is an electrolytic capacitor.

There's a tutorial with schematics on the JLN Labs page (in French):

Blew the thick dust off my mighty breadboard. I didn't have any 9 V batteries laying around, so I took 4 dead AA batteries that totalled up to 2.78 V or so. Took a 22 uF 16 V cap and a 3.3 V LED. Put it together at t0.

Measured the batteries the next morning (t0 + 9 hours) .. still 2.78 V.
Measured the batteries just a few minutes ago (t0 + 20 hours) .. 2.86 V.

Very cool. The LED still isn't lit yet .. but it probably will be. In the meanwhile, bought a couple of the cheapest (lowest mAh) 9 V batteries. Should order some supercaps and try charging these, too.
