Yes, and that reminds me of something interesting, but off-topic. I once asked a solid-state physicist at my institute if he could make an "anti-microwave oven" that would cool beer. And he said it would be impossible, and gave me an analogy that I think is really cool (or at least gave me the seeds of the analogy). If you blow a wind into a forest, you will easily make the trees sway, but to try to blow a wind into the forest to stop the trees from swaying is really tough, since they are all swaying in different directions and velocities. He kind of said, if it was a single type of molecule, it might be possible, but if you have a mixture of molecules, it's going to be basically impossible.
