-80c is 193K. Looking at https://en.wikipedia.org/wiki/List_of_superconductors there are 3 superconductors that work at that temperature or higher. But they all need very high pressures (150 GPa or higher). Which is close to the pressure in the centre of the earth (380 GPa). A more reasonable superconductor that's widely used is YBCO, which at 95K (-178c) is cooled using liquid nitrogen. And I believe that's at normal pressures. |
