We all know that the increasing concentration of carbon dioxide in the atmosphere has a major impact on the Earth climate. But now, chemists at the University of California at San Diego (UCSD) have developed "a device that can capture energy from the sun, convert it to electrical energy and split carbon dioxide into carbon monoxide and oxygen."As carbon monoxide can easily be converted to liquid fuel, this prototype device kills two birds with one stone: it helps saving fuel while reducing the concentration of a greenhouse gas. Still, this device needs some improvements before an industrial deployment.
