Silicon chip breaks “blackbody limit” to produce more electricity from heat than thought possible

Energy conservation is a no-brainer and more important than ever, but it’s not just about environmental implications. If we’re to successfully create smaller, better, more efficient technology, then the thermal energy that our gadgets waste needs to be put to much better use. This new device, which works at the nanoscale where the theoretical “blackbody limit” falls apart, could be the answer.
