Scientists Found a Way To Cool Quantum Computers Using Noise (sciencedaily.com) 7

Slashdot reader alternative_right writes: Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

in an alternate future where the Russians beat us to the moon and Apollo never ended, we did this in 1973..

Well, in that alternate future, the surface of the moon might be glowing, but that's not a reactor. :-)

It certainly got close to that. If you haven't watched, definitely check it out. Pretty amazing show.
