So they arent counting magnets/magnetism as a source of energy like a battery then? However I'm sure these newer stronger possibly more directional/controllable batteries will have an effect in electric motors in the future. I think the newer higher temperature super conductors helps, but then I wonder if the cooling facilities of the older generation of super conductors might have been a potential future safety feature on earth but not in space.
