RE: Why room-temp superconductors probably won't help computers much, if they exit at all.

Here's what I read from this website ;

The latest room-temp superconductor claims are losing their magnetism after several labs failed to replicate results.

Lead isn’t typically on the short-list of materials that researchers in the field turn to.

There’s a hitch, though: Today’s superconducting materials have to be chilled well below freezing before they do anything special.
