"this stuff is claimed to superconduct all the way up to room temperature and indeed up past the boiling point of water. Its critical temperature is said to be 127C" Would this have implications about possible efficient methods of converting heat back into electricity? Or even just more ways of harnessing heat energy in general. I'm imagining heat pumps built with superconductors could be a critical part of mitigating climate change, but I'm far from a scientist and barely understand the physics here.
