The cubes can then be deployed in a variety of applications, including mobile generators and temporary EV chargers. GM said the ideal application would be at an outdoor concert venue, thanks to the hydrogen generator’s much lower noise profile as compared to gas-powered power sources.

Why a “room-temperature superconductor” would be a huge deal

Vox

Superconductors are already employed in certain limited applications for storing energy. Batteries — from a Duracell AA all the way to a Tesla lithium-ion battery capable of holding approximately 100 kWh — store energy chemically, and can convert it to usable electricity. That necessarily involves some energy loss and inefficiency.
