Copper Indium Gallium Selenide - not just for solar cells anymore

The heat conversion properties of Copper Indium Gallium Selenide (CIGS for short) have long been one of the primary elements of photovoltaic cells.

But according to Discover magazine, the alloy is being put to different uses. They can also be used for, say, converting the heat from factories into the electricity used to run the factories. This doesn't mean that said factories will suddenly become the industrial equivalent of a perpetual motion machine, but it could cut down on outside fuel costs and reduce dependence on ubiquitous and dirty coal-powered electrical plants.

Research is also going into vehicles. CIGS can be used to convert heat from car engines into the electricity needed for radio, AC and other non-locomotive functions of a vehicle, seriously reducing the draw on batteries and saving consumers money and the hassle of needing a jump if the heat-generated power can be stored efficiently.

It isn't quite comic book science fiction Halo technology, but it's step toward fuel efficiency and keeping dirty car batteries out of landfills.
