Generally "high-temperature" means liquid-nitrogen temperatures - in general, 77K is a common lab benchmark for these materials.
EDIT: See, for example, this paper on the superconductor in question, which gives properties at 77K and zero magnetic field: https://www.sciencedirect.com/science/article/abs/pii/S0921453497001202 https://www.sciencedirect.com/science/article/abs/pii/S09214...
- Dylan16807 8y agoThey're cooling it to about 30K, at which point nitrogen is frozen solid.
- azernik 8y agoInteresting. That's around the liquid hydrogen range - still cheaper than helium, but probably not as easy to work with as nitrogen. I guess their requirements for critical field were high enough that the 77K GdBaCuO performance wasn't good enough?
- Dylan16807 8y agoGoing by the link stephen_g found, it has around 1.8x the needed capacity at 30K, 1x at 50K, and 0.2x at 77K.
- ginko 8y agoGiven the spectacular ways wind turbines can fail, I'm not sure if I'd like liquid hydrogen to be involved there.
