I was wondering how to store energy in the best way. I got this idea displayed in picrel.
A superconductor is coold to the appropriate temperature and layed in a circle. We put energy in it to create a current which just flows in a circle. Because of the lack of elictrical resistance, we wouldnt have any energy losses, so we could just have this energy going circles to keep it saved. Later we could take the energy out of it again. This would be a way to save electrical energy with multiple advantages over accumulators. They wouldnt age and the capacity wouldnt be limited like accumulators are. But there could be magnetic fields that could cause problems, i dont konw about that one. What do you think?
