What's important is what you can use to cool it. Using helium to cool traditional superconductors is expensive and bulky. If we can cool superconductors with small Peltier coolers or your traditional fridge setup, that's a huge advantage.
- ramraj07 3y agoIf this was the issue, aren't Peletier coolers already able to reach -80 deg C already? I remember our research camera sensors being cooled to that temperature withoutbfuss and being there for months on end.. surely some other superconductors work at this range!
- ShockedUnicorn 3y ago-80c is 193K. Looking at https://en.wikipedia.org/wiki/List_of_superconductors 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.
