(Source: US Department of Energy) Can we turn carbon dioxide into fuel, rather than a pollutant? A group of researchers asked that question and found a way to say yes. In a new study from the U.S. Department of Energy's Argonne National Laboratory and the University of Illinois at Chicago, researchers were able to convert carbon dioxide into a usable energy source using sunlight. Their process is similar to how trees and other plants slowly capture carbon dioxide from the atmosphere, converting it to sugars that store energy. One of the chief challenges of sequestering carbon dioxide is that it is relatively chemically unreactive. 'On its own, it is quite...
