Researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small space that current methods can’t remove heat quickly enough.
This could turn out to be important for future smartphones and other computers. With more computing power in smaller and smaller devices, removing the heat from the microprocessor is beginning to limit how much power can be squeezed into a given space.

I wanted to add more, but as my house started to runaway towards zero Kelvin, my fingers were freezing and slowing down too much to continue. I was posting from my phone, and I can’t be arsed porting my password manager across, so posted as AC in my ice cold A/C, while feeding AC back to the grid.

Sucks to be so greedy, ain't it?
If you would only export half of it and use the other half to heat your home, you wouldn't become super-conductive.

Not greedy as such. Just forgot the thermostat and without the laws of thermodynamics to asympote it towards an energy equilibrium it got out of hand. Barely made it to the off switch before I was too frozen to move.

Carnot is a bitch when it comes any useful energy from heat differentials.
