Scientists from Cornell University developed a technique that sucks up CO2 from exhaust streams and generates useful electricity as a byproduct. The device they’ve built is a kind of electrochemical cell. Think of it as a building block of batteries: It knocks electrons out of aluminum, channels them away, and leaves behind a form of oxygen called a superoxide. In air that is made up of 80 percent CO2 and 20 percent regular oxygen (as opposed to the atmosphere, which is about 21 percent oxygen and 79 percent nitrogen), the superoxide grabs the CO2 and forms a type of bleach used by pharmaceutical and textile industries, as well as in antifreeze and plastics. http://www.bloomberg.com/news/articles/2016-07-20/the-newest-way-to-clean-the-atmosphere-make-bleach
