Keep in mind that superconductors have a critical current below which you have to be if you want to stay in the superconductive states. So for a superconductor to be useful for energy transport, this current has to not be tiny. I haven’t had the time to read their paper so I don’t know the value of the critical current. Also if for some reason the current suddenly goes beyond the critical current, the wire will heat suddenly, with possible damage…

I didn’t know that. Thanks.

And sometimes superconducting materials are wholly impractical -- making it superconductive could make it incredibly brittle, etc. Supposedly this new material is an "apatite", which is a geological term for a kind of crystal. Who knows what properties it has, yet? Supposedly these samples were made and tested by depositing them on to a glass surface.
