Yesterday I wrote about the Norwegians scrubbing CO2 out of natural gas. Something else people are working on are giant CO2 scrubbers for the air. These scrubbers could be placed around the planet and work 24/7 to remover massive amounts of CO2 from the air. The scientists working on these scrubbers believe that there is the potential to take enough CO2 out of the air to put us at pre-industrial CO2 levels. Pretty amazing stuff. You can learn more about both these project on Discovery Channel.
