If you thought photovoltaics can only get energy from the Sun, then you were wrong. An MIT team of researchers have invented a device that produces electricity from heat. The process uses the photovoltaic effect as the middleman and is three times more efficient than the most efficient lithium ion batteries on market today.

According to a new study, heat pumps are not so efficient in extremely cold climates, only being suited for moderate climates. These provide cooling in summer and heating in winter. Researchers at Purdue University have recently developed a new type of heat pump that allows residents in cold climates to halve their heating bills, due to its high efficiency.

GM's R&D has to build a prototype of a thermo-mechanical waste heat recovery system using a Shape Memory Alloy (SMA) heat engine to generate electricity from the heat in exhaust. Noticeable is the fact that GM was between the 37 other candidates that received the ARPA-E award.

This article doesn't talk about huge producers of energy, or doesn't mention the use of any prime matter to create energy, but instead it focuses on recycled one. Ener-G-Rotors, a company based in Schenectady, NY, is developing a heat recycler that can work with lower quantities of heat, under 150°C, unlike those of the competitors, aimed only to the higher-class, industrial energy producing stations.
