Removing CO2 from the Atmosphere

Alongside research to reduce the amount of carbon dioxide (CO2) from emissions is research to remove the greenhouse gas from the air. Unfortunately most of the traditional methods are energy intensive and don’t work well, amongst other issues. Now being reported in the Journal of the American Chemical Society is news of cheap compound being used to capture CO2 from the air.

Polyethylenimine is cheap and readily available material and has achieved one of the highest CO2 removal rates ever observed, for humid air. To further impress the researchers, the material is able to quickly and easily release the CO2 as well. Though it may seem odd that researchers would want to release the captured CO2, the gas can be used to make other substances. For example, recaptured CO2 could be used to create gasoline or petroleum based plastics and medicines. Alternatively, the CO2 could just be sequestered somewhere permanently while the cleaned polyethylenimine is used to capture more CO2.

PLANTS remove CO2 from the atmosphere - Algae grown in enormous 'Atolls' at the Mouth of the Mississippi would prevent uncontrolled algal blooms that lead to 'Dead Zones' in the Gulf. The algae farmed could be HARVESTED to be made into ALGAL OIL FUEL like that the US Air Force has Contracted to be produced. The ADDED BONUS is Hurricane Protection from the New Barrier Islands.
