Last year, South Korean researchers made headlines when they claimed to have discovered a room-temperature superconductor, which they called LK99. One reason for the excitement is that such a material could enable super-efficient power transmission lines, minimizing the amount of new infrastructure needed while distributing the gigawatts of clean electricity currently coming online.
The LK99 was a failure.
