Recently a friend of mine threw out a question that I thought I knew but on closer thought didn't seem likely. We were thinking about energy transfers and whether removing heat from an object or the air could be done in a way as to store the heat as energy. Basically, we were thinking that in theory there would be a way to steal energy from something by removing the heat. Obviously we have no idea how to do this but the theory seems sound. What we were thinking, in analogy, is if we looked at a bucket of water and envisioned the bucket as a room and the water as the energy of heat, would there be a way to suck the water (heat) out of the bucket (room) such that there would be a viable source of water (heat or energy) collected and stored for other purposes. It seems this is possible, though niether of us could think of how or what the process might be called. But what we couldn't agree on was whether the same could be done with cold instead. In the analogy, were one to suck the heat out, we'd figure it would leave the room cooler, but what we really want to know is whether one could "suck" (for lack of a better term) the cold out of a room and make it hot, without bringing in something burning or some source of heat added to dissipate the cold. Basically can you rob cold from a room to generate heat without inserting any heating agents.
