Researchers from the University of Minnesota have announced a breakthrough in the quest to create a viable fuel alternative using greenhouse gases. The process uses two types of bacteria to create hydrocarbons from sunlight and carbon dioxide. Those hydrocarbons can in turn be made into fuel, which the scientists are calling "renewable petroleum."
