"Maybe there's a true thermal superconductor out there to be discovered..."
it's called a vacume, and honestly I believe that for heat, thats it, given it's role in physics....
- apothegm 7mo agoVacuum? It’s a terrible conductor. Closer to a perfect insulator.
- MisterTea 7mo agoIt's a perfect conductor of infrared radiation which is how we cool space stations without ambient air to remove the heat via convection.
- apothegm 7mo agoIndeed. But radiative cooling in vacuum is much slower than conductive cooling per unit surface area (even just in air at sea level on earth, air being a fairly poor conductor) unless you manage to concentrate the heat in your radiator at a massive temperature that most materials can’t withstand. And conductive heat transfer is what’s being measured in the context of this article.
