Superconducting materials can do amazing things that appear to defy the laws of physics, but their major drawback is that superconducting properties don’t appear unless a material is cooled to near absolute zero.

Superconductors that would work at (or near)  room temperatures would, without exaggeration, would change the world and would have massive implications for quantum computing.   

Liv Boeree shares this exclusive behind-the-scenes interview with the scientists who just unearthed one of the holy grails of physics: a room-temperature superconductor!

Their discovered material — carbonaceous sulfur hydride — shows superconductivity at 15 degrees Celsius, a temperature FAR above all previous records. It takes us a huge step closer to the long-sought goal of creating electrical systems with perfect efficiency, which would transform the world’s energy grids, computation and transportation systems entirely.
