Shorting coil gives back more power

[romerouk]

now after almost 6 hours I need to change or discharge the battery, is shows 7.2volts.
I had no load at all, not even the LED's connected

Well done Romero !
Keep at it and let us know, if you could get it to selfrun just on
a cap.
Many thanks.

Regards, Stefan.

Have you tried rundown test runs, like how long from 1000rpm to 0 with and without the shorted coil?  This will give you a better idea.  If you have a meter that can measure hz, you can set up an rpm sense coil so you know what speed to start the timer.

You might find some drag, and also this method can help you lessen it possibly by trying different things.

Hi. Since my understandings are on the pop-sci level, I have a stupid question: is it possible to obtain all these nice effects presented in this thread, using an L-C oscillator?

Hi, again. I found a link, of which content can be useful for experimenters: how to make a Zinc Negative Resistance Oscillator: http://home.earthlink.net/~lenyr/zincosc.htm
