Energy news and Small Homes

http://www.futuristech.info/4/post/2014/01/video-solar-energy-efficiency-to-be-improved-by-harvesting-heat-energy.html Researchers at MIT have developed a solar thermophotovoltaic device that experimentally demonstrates a three-fold increase in energy conversion efficiency. Their device builds upon solar thermophotovoltaic technologies, adding a nanophotonic absorber-emitter that is tuned for optimal collection of sunlight and thermal emission above the photovoltaic band gap.
