| Scientists Make Fuel from CO2 Emissions and Sunlight Posted: 26 Nov 2009 10:52 AM PST Scientists from Sandia National Labs have successfully field-tested a machine that uses solar energy to convert CO2 waste from power plants into fuels such as gasoline, diesel, and jet fuel. Cylindrical in shape, the device has both a hot and cold chamber with 14 Frisbee-like rings in the middle. The rings’ outer edges–made of iron oxide–are solar heated to 2,700 degrees which forces the composite to lose oxygen atoms. As the rings rotate (one revolution a minute), they move in towards the cool chamber. There, carbon dioxide is added and the iron oxide composite takes back its missing oxygen atoms. The resulting carbon monoxide would be used in creating a synthesized liquid combustible fuel.       |
