Superconductivity fight

Preprint server removes ‘inflammatory’ papers in superconductor controversy

This is about that business of high-pressure room-temperature superconductors (i.e. "we got them to work at room temperature we only need a huge pressure to do it") as opposed to normal-'pressure low-temperature superconductors (i.e. "we got them to work at normal pressure we only need a low temperature to do it"). The low temperature is probably easier but yeah, room-temperature superconductors, if you believe the results, which there are obviously some who don't.

The temperature of superconductivity was a hot topic back in the 90’s when I was learning about it. Terrible straight-line extrapolation from essentially 2 groups of data points to show how it was all but inevitable that we would get room temperature superconductivity sometime soon. Motivated reasoning in abundance.
Would you like your chakras realigned?

Our lecturer had just written a textbook on superconductivity in which he wrote that he'd left the chapter on high-Tc until last in the hope that someone would have figured out how it worked by the time he got around to it. That was also back in the 90's.

Really high temperature superconductivity would be fantastic for fusion power... ;)
