"Yeah thats pretty stupid. The question doesnt even asked anything relevant to anything. I've taken thermodynamics and heat trasnfer and this doesnt make sense." Chipotlehero, it's a violation of the 2nd Law of Thermodynamics (also known as the Kelvin-Planck statement). In order to move heat from a low temp to a high temp you'll consume energy (for example a refridgerator). So please, next time you want to play expert can you try to know what you're talking about?
