While governments around the world continue the long, hard work of regulating away the future use of fossil fuels, scientists have discovered how to remove carbon dioxide already in the atmosphere. Researchers at the Oak Ridge Laboratory unexpectedly discovered a chemical reaction that converts carbon dioxide into ethanol. This discovery was made as the researchers attempted to uncover a series of chemical reactions that could turn CO2 into fuel. As it turned out, the first step in this series of reactions was quite enough to make it happen. The resultant ethanol is a cleaner fuel that could be used power generators or vehicles.
