Hey, I bet I’m not the first but superconductivity is defined by a 3-d surface where one axis is the temperature. The other two are current density and magnetic field strength. Here’s a random pic. Cheers!

Like Ken said superconductors have a critical current density, if you exceed it they stop superconducting. So you can’t put 10,000,000 amps through a hair.
Regarding maglev, most of the energy goes into pushing the train through the air and not levitation, so superconducting wouldn’t change much. Even in regular trains most of the resistance comes from air and not the rolling wheels.
I also had a revolutionary idea for charging scooters, wireless power beaming. LOL

Yes, please!!!! And please grow a beard, too!
Dave will always choose PIC. I was ROFLing on that one!
