Tired of the air not doing enough for you? Well, a new project called Green Freedom -- headed up by researchers at the Los Alamos National Laboratory -- seeks to improve air's contribution to our planet. The new technology would provide a method of extracting CO2 from the air and then converting the gas into fuel for cars or airplanes -- thus sucking out toxins from our atmosphere while creating a renewable energy source. The process uses a form of electrochemical separation to siphon juice out of the typically poisonous gas, yet has a low environmental impact with a small waste-stream output. The plan calls for the use of existing plants, which will stem the need to build new facilities, enabling the environmental footprint to remain relatively small. Clearly, it's n
