For this to work, the wire's surface must be extremely clean, allowing electrons to move freely and spread along the wire to create a uniform temperature. A material with a critical temperature of -193 °C could superconduct at room temperature, provided some sections were kept to -253 °C, they found. In principle, the colder these refrigeration points are, the fewer you need, Dubi says.

Okay, thanks! But it reads like this guy's name is really spelled Doobie. ;') Thanks allmost and decimon.

To shake Tesla’s hand, ask him a question...

Considering this is an innate state of the conducting material itself I'm highly skeptical.
Quantum effect?

That joke would work even if part of it were not supercooled.

The width and breadth of the effect would have to be astronomical in proportion. Please. Bug the the hell out of me if find it...

Unfortunately Tesla is beyond our current reach. But the US Government confiscated many of his notes we’ve never seen.
