I used rock because it helped me figure out the scale of the lithium capacitors. The device initially had multiple, much smaller capacitors which, though it had helped ensure a more constant electrical flow, had heated up a lot faster than the current iteration, causing it to lose charge. With V3, if I get around to it, I plan on maybe layering water so that there's a higher amount in the reactor and letting it run longer without having to rely a little bit on the capacitors.
very cool. but energy isnt conserved. Keep up the good work. +1
us there a specific reason you used rock? i thought it didnt have any special properties.
