New Compact High Temperature Superconductor Cable

In the superconductor field, "high temperature" means liquid Nitrogen and above. Liquid Nitrogen is cheaper than milk. You can also buy a compressor and refrigeration system to make your own for about a million dollars.

This material, that can handle a flux of 2800 Amps in a 7.5mm diameter cable brings it close to the time that fermionic coupling of Heim Theory can be tested. Give it another year or two.

No, it doesn't. It means more like "over 30k".

I do note that someone has added additional definitions, the last of which covers yours. However, it seems to apply more to the "technical; applications" field rather than the SC field itself. None-the-less, in the context of this thread, it is still bite-a$$ cold.

Nevertheless, cooling something down to and maintaining it at 30K is far easier and cheaper than 4K, which is the temperature of liquid Helium.

Heck, you can use Neon rather than Helium.
