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 creating a renewable energy source. The process uses a form of electrochemical separation to siphon juice out of the typically non-partying carbon dioxide, 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 not being put into general practice yet, but it's a hopeful taste of things to come.
