Could you create an AC that recycles its displaced heat?
Since AC’s work based off of moving heat from one place to another, and basically all energy-producing systems work based off of converting heat into mechanical energy, could you not create an AC that recycles the heat it displaces into a generator of sorts that goes back into powering the unit ?
Obviously it wouldn’t be able to power it fully, and i haven’t crunched any numbers on the matter to know if the amount of electricity saved would be in the ballpark of being useful, but it could at the very least be more economical, and reduce the adverse effects of everyone having their AC pushing heat outside and making it even hotter.
Would this not work for some reason or would it work but not be worth doing? Apologies if this is an already commonly known thing.
