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.
