If (and that's a big if) you could devise a superconductor that can operate at room temps, and IF it could be made with reasonably affordable materials...
The main impact would be on electric motor and generator efficiency, at least initially.
A typical copper wound AC generator peaks out at about 91.5% efficiency at converting mechanical force to electric power (and often can be as low as 85% under real world conditions). For superconductors, the theoretical peak is around 99.5%.
"That last three percent, it may not sound like a lot, but it is. It's tremendous."

Unfortunately, no.
Apparently this new material is a ceramic and cannot be used in wires.
ObBreakingBad: Also practical EMP. That magnet scene in season 5 would actually be possible.
