I certainly don't know.
But room temperature superconductivity would certainly be a boon. Be interesting to see what might happen with a maglev train, for instance, when the magnets got too hot.
Might just kinda roll to a halt, unless there were no wheels.
Anyway, I think 'they' will arrive at room temperature superconductivity.
And if that really has been cold fusion the last two reports, then 'they' will find a way to make it productive, too.
