So I saw some papers on arXiv that explore the notion of playing around with the Stefan-Boltzmann law using metamaterials: http://arxiv.org/abs/1109.5444 http://arxiv.org/abs/1411.1360 I know enough physics that it looks rather interesting, but I don't know enough math to judge how credible it is, particularly since I was a little unclear if the system was actually built and tested or not. What are people's take on it? p.s. I put this in the Quantum Physics folder due to the Stefan-Boltzmann law ultimately being a quantum mechanical phenomenon. If a different folder would be more appropriate, feel free to move it.
