> With regards to turning it back into electricity, that is not feasible due to the way entropy works. You would just generate more heat than electricity in the process I'm aware that it would be wasteful, but you already have the heat. As it is vented from the ac to the atmosphere at the moment as a total loss, generating any electricity at all must be a win? Something like a Sterling engine, perhaps?
