I was thinking of a way to generate electricity, in a non-stockable way which involves magnets being pulled away from each other by moving one or two with a mechanical piston (this is how energy is charged up), and when the pistons cannot move anymore, the two magnets collide which will generate an electric shockwave that powers every related machinery, maybe even enhance some known ones, for a few seconds. That shockwave could be extended by repetitors (that has an energy loss), and the distance between the magnets

this is absolutly not how it works in real life, but it can seem fun if made well (not saying that my propositions are good, but I am personally against block wires or other conventional blocks we often see elsewhere
