Hello everybody! I was wondering today if physically, it'd be possible for the world to develop an air conditioner without an outdoor heat unit? I know this seems to violate the second law of thermodynamics, but the known version of the second law thermodynamics only consider this is impossible for devices that converts heat to work.
What about other types of energy? For example, if the heat I take out from a room in the infrared spectral range could be transformed by some process in energy in another spectral range, that my body does not perceive as "hot", or if this energy could be transformed to chemical or electrical energy, even charging a battery. Is that possible?
I know the process need to always increase the universe entropy, and decreasing the temperature of my room will always decrease the entropy, such that I would need another process that increases it. But can't humans develop some other process that deal with all the heat that should be generated and transform it in another energy type with a higher entropy? Specially if we could store it?
Thank you very much!
