Is there any material that readily absorbs heat at wavelengths between 8 and 13 micrometers? Instead of beaming the heat to space, could you instead put that special coating on a parabolic reflector and use it to heat up an absorbing material at the focal point? And then put a frying pan on top of that and cook an egg?
- analog31 9y agoThere's a statement of the 2nd law of thermodynamics, that forbids you from passively transferring heat from a cold body to a hot body.
- kardos 9y agoAh of course. So best case it can accelerate warming cold things to ambient temperature
- mlonkibjuyhv 9y agoIt's completely unnecessary. In a system capable of doing that, you might just as well boil your eggs at the source. Thermal equilibrium, and all.
