I wonder if you can achieve overunity in just solid state
Using nothing but the Electronics found in Disposable single use Cameras
Linking the Flash Charge boards together in such a way
That When ones changed it will then starts powering and changing up the next in line till eventually all are changed up and become in a constant state of charge.
Neat thing is capacitors tend to have "15 years Memory" and even recharge them selves with no power even after being discharged
so link all the caps so they remain individual but can be link to make one big kick starter that feds into the first cap to start the whole process
