After a very quick trawl I came across this article. This was the closest I found to getting 2xO and 1xC in the five minutes I devoted to it: 1xO and 1xCO, carbon monoxide.

So these guys have a product in their labs that can use solar energy to convert CO2 into oxygen and the necessary feedstock to create synthetic energy products. Surely this is the ultimate Green Tech product in the making?? Something that uses the sun's power to get rid of greenhouse gas carbon dioxide, give us much-needed oxygen and a source for alternative energy to help reduce dependence on oil/gas.
Why wasn't this all over the media? That article was out almost 2 years ago now. Why isn't this product being heavily invested in and by now rolled out on a massive scale to fix the (claimed) climate change issue cause by (supposedly) carbon dioxide? You think that maybe the people who will make a lot of money out of carbon trading, wouldn't make any money out of a product like this? Just call me cynical.
