A Bedini circuit I built with a reel to reel motor John gave me
a few years ago.

Pretty cool and interesting SG. Very fast and very efficient.
Charges batts pretty good. I never measured efficiency. If I put
1 batt bank on the output or 4, it doesn't really change the input
it doesn't care. Of course can grab the shaft to increase the load
and the input does not increase.

5000 rpm it draws 1 amp avg
10,000 rpm it draws only 1/5 of an amp avg
