Converting CO2

A group of scientists at the University of California, San Diego have constructed a prototype of a "splitter" that converts solar energy to electrical energy and then divides that CO₂ into CO and O. That CO is carbon monoxide is a renewal energy source and is much more environmentally friendly than its double-oxygen progenitor. Carbon monoxide is nowadays produced from natural gas, which isn't always in large supply and can be quite expensive to tap into a fuel source. The UCSD "splitting" device would seem to bypass that problem by taking an emissions producer and turning it into renewable energy. http://www.mobilemag.com/content/100/313/C12398/
