They are pushing for ever higher transition temps, they think they will get it to room temperature, I'll believe it when I see it though. 151K is pretty significant as it stands and the next question can it be scaled up to commercial levels? Nice if you can make a 2 cm long strip that becomes superconductor at 151 K but we really need thousands of kilometers of the stuff.
