I have read in several places that superconducting materials are the closest phenomenon to perpetual motion known to science (constant flowing electrons within a circuit without resistance). The problem is that the energy required to cool the inducting material to its superconducting temperature would be far more than would be produced. However in space we have two advantages. One is the fact that it is a frictionless vacuum environment (you could rotate a disk with magnets on it without friction resistance) and the second is that parts of space are near absolute zero. Therefore theoretically you can have a free rotating dynamo inducting on a superconducting material at the surrounding ambient temperature. There would be no EMF feedback to slow the rotation of the disk. The freely moving magnets would induce a current on the superconducting coils without resistance. The energy could then be stored or used. And no energy would have been consumed in cooling the coils to superconducting temperatures. I must have missed something? Won’t this work?
