While these inventions are certainly miraculous, they are still cumbersome as these materials constantly require ultra-cool temperatures (usually in the form of expensive liquid helium)—not exactly something that can feasibly cover the millions of miles of cable that make up the U.S. electric grid.

But if science could somehow discover a material that acts at a superconductor at room temperature, our electric world would enter an entirely new era.
