... if true, this is one of the big ones. Like the discovery of atomic fission, which led to power plants and bombs.
This one leads to a lot of sci fi shit. We could never transfer energy without losing a big chunk of it to waste heat, waste that builds up and ruins everything eventually. This has held back electronics, and really almost all electrical applications for a long time.
This would fix that. Room temp superconductor is your phone no longer getting hot, your computer no longer needing a fan system. It's also easy maglev and small supercomputers.
