Room temperature superconductors would make a lot of new things possible, like smaller and better motors, generators, RF filters, low frequency antennas, etc.

Room temperature superconductors would make a lot of new things possible, like smaller and better motors, generators, RF filters, low frequency antennas, etc. No matter how slow you needed a load to turn, you could wind a motor to do it without gear reduction. Gear trains in large scale wind turbines are a huge maintenance issue, and failure mode. With superconducting generators, they could be converted to direct drive. The only limits are critical temperature and critical field strength.
