Probably some kind of horrific bomb.

It looks like the big technological leap in relation to 'How can we use superconductors to hurt things' is to use them in making advanced EMP devices. It doesn't seem like anyone has figured out any other obvious use cases for them that massively change or improve upon the other horrific devices that we've already come up with.

In regards to potential for use in war crimes, it could be a lot worse.

One thing I could think of would be miniaturized railguns. A large part of the bulk in rail guns at the moment is the cooling system for the electro magnets and capacitors to deal with inefficient power delivery.

A room temperature superconductor would fit both problems.

That would make some orbital insertions a lot cheaper, too.

Railguns have the unfortunate side effect of applying their full acceleration over just the length of their rails, which tend to be relatively short compared to the thickness of the atmosphere.

They're fun to shoot some bullets at hypersonic speeds, not so much to impart higher than orbital speeds to complex structures when they get pancaked before leaving the muzzle.

Room temp superconducting magnets should make motors and power generation a bit more efficient. Magnetic plasma confinement gets a shit load easier as well.

Those are currently viable with conventional technologies. Explosively pumped magnetic coils with some big-ass capacitors. You could probably do something similar with a spark gap instead of a coil.

Room temperature superconductors would make them easier to build. Probably smaller.
