Need, no, but it would be awesome. In fact with enough excess energy we could afford to generate enough liquid nitrogen at scale to have superconducting lines

In fact with enough excess energy we could afford to generate enough liquid nitrogen at scale to have superconducting lines to improve efficiency.
- nine_k 2y agoThe problem with the current crop of REBCO superconductors is not the cryogenics but the actual ceramic material being brittle. You can't make a wire or a cable, you can only operate with stiff, thin, fragile bars. On top of that. it's not cheap, $100-200 per meter of typical 200kA power band. I suppose copper is like an order of magnitude cheaper just for the cable, ignoring the whole liquid nitrogen piping.
- nullc 2y agoThe critical field in high temp superconductors is also much lower, which limits the current you can put through it.
