Unconventional superconductors contain a number of exotic phases of matter that are thought to play a role, for better or worse, in their ability to conduct electricity with 100% efficiency at much higher temperatures than scientists had thought possible—although still far short of the temperatures that would allow their wide deployment in perfectly efficient power lines, maglev trains and so on.
