    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…

      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.
