Turning Carbon Dioxide into Fuel

Could concentrated solar energy be used to reverse combustion and convert carbon dioxide back into gasoline? That's what scientists at Sandia National Laboratories, in Albuquerque, NM, aim to find out by building a novel reactor that can chemically "reenergize" carbon dioxide. The device uses a two-stage thermochemical reaction to break down carbon dioxide to produce carbon monoxide, says Nathan Siegel, a senior member of technical staffat Sandia's Solar Technologies Department and one of the...Full Story
