Researchers believe that artificial photosynthesis that sucks excess CO2 out of the air could one day help fight climate change. But capturing the gas is only half the challenge. The other half is what to do with it once you've got it. Lauren Sommer reports on a potentially breakthrough technology that uses artificial photsynthesis to turn CO2 from the air into industrial chemicals and natural gas.
