Stanford Ovshinky’s Energy Conversion Devices Inc company in Troy, Michigan is claiming a phenomenal improvement in high temperature superconductivity: the University of Houston reckons it has got a ceramic to superconduct at minus 48oC, which is pretty hot if you don’t have to go out in it, but Ovshinsky’s mob have what they call a multiphase ceramic material that has a varied composition and reckon they have detected superconductivity in one phase of the material at a remarkable minus 13oC – the sort of air temperature we had last winter; across two contiguous phases, their new stuff superconducts at around minus 105oC or so.
