One of the biggest problems with computers, dating to the invention of the first one, has been finding ways to keep them cool so that they don't overheat or shut down.
Instead of combating the heat, two University of Nebraska-Lincoln engineers have embraced it as an alternative energy source that would allow computing at ultra-high temperatures.
Sidy Ndao, assistant professor of mechanical and materials engineering, said his research group's development of a nano-thermal-mechanical device, or thermal diode, came after flipping around the question of how to better cool computers.
"If you think about it, whatever you do with electricity you should (also) be able to do with heat, because they are similar in many ways," Ndao said. "In principle, they are both energy carriers. If you could control heat, you could use it to do computing and avoid the problem of overheating."
They documented their device working in temperatures up to 630 degrees Fahrenheit (332 Celsius).

Electricity also only flows in one direction.
Presumably, a "heat diode" would allow heat to flow in one direction or prevent the flow altogether.

A thermal diode would likely obey the law of heat going from hot to cold which is equalization in reality. But a diode would then prevent the flow in the other direction. Hence diode..
To get cold into a hot mass there needs to be a heat pump. Which then uses power and has inefficiencies.
