High-temperature superconducting tape for magnets at 50+ tesla

This should have implications for various nuclear fusion reactor designs:

"High Temperature" is relative. The paper shows they're working at 30 K and below, and the performance falls off at high current in the 30 K tests. Performance at 4.7 K is outstanding.

Liquid nitrogen runs about 77 K, so you don't get this sort of performance at liquid nitrogen temps. This means I can't build my own 50 T magnets yet.

I'd be so happy with my own 5 T Polywell, I could just sing! Let these guys play with their 50 T projects ... I personally am too careless laying down tools and having stuff in my pockets to come anywhere near such a monster! I can just imagine the safety rules you would need to work in such an environment!

Welders need not apply. :D
