TIL: superconductivity at 100K

[timelets]

REBCO becomes superconducting at temperatures of around 90-100K, rather than the 4K critical temperature of Iter’s magnets; this means that cooling can be achieved with liquid neon, hydrogen or even nitrogen rather than liquid helium, making cryogenics simpler and cheaper.

Nitrogen would be totally cool!

That would be the holy grail, but it looks like a stretch now.
