Wait, are they saying 33 Kelvin is high temperature when it comes to super conductors?

Traditionally (or at least when I was at University ~20 years ago) anything above 30 Kelvin is considered a high temperature super conductor.

Not really, I think that now superconductors that can be cooled down by just liquid nitrogen are considered high temperature. That’s 77k.

I am not sure why they put the -240C figure in the article, but if their superconductor really needs that temperature then it’s not high temperature.
