Alas no amps to amount to any thing. I still think it is neat

Its astonishing that it works. To use electricity you need the push(volts) that it has. But to get it to do work you need current or flow(amps). It is a weak spark and it takes it while to build up. So there is not much amps to work with.
Walter Levin was using it to make more of way to get his students to think then suggesting that it will work as a power source.

...as if I don't have millions of better things to do.
Neat toy. The most puzzling aspect about it is it's symmetry, at least for those who have not studied bistable systems.
