There is a reason why room temperature (ambient pressure) superconductors have been one of the holy grails of physics for such a long time: the implications are profound.
I used to be a particle physicist, and some of the more complex systems were just those used to cool the superconducting magnets down to cold enough that they become superconducting. If you can do that at ambient temp, you don't have to bother with that entire system.
Also: fusion reactors rely on superconducting magnets (or if you are JET live with the fact that you can only run your magnets for a few seconds before the overheat), so can have a large impact on future fusion reactors.
