Captue CO2 Molecules Directly From Open Air


Everyone have a opinion and discuss about global warming,but these not help things very much,so we need to reduce urgent carbon emissions.
The Atmospheric Carbon Capture Systems (ACCESS) Air-Capture System, developed by Global Research Technologies in Tucson, Ariz., holds sheets of material capable of capturing CO2 molecules directly from open air. The system not only captures atmosphere CO2, but it also stores it for a considerable amount of time. To remove the molecules, the sheets are sprayed with a chemical solution that bonds to the carbon dioxide. The solution is then drained off to a separation unit, where the CO2 is isolated as pure gas through electro-dialysis.
A design goal was to avoid using toxic or corrosive chemicals that would require special handling, so ordinary PVC pipe is used to transfer the solution back to a collection unit so that it can be recycled.

The Access machine aims to capture atmospheric carbon, but storing it and re-using it for long term purposes, will always be difficult. Instead of all this, maybe one would do just fine to plant a few trees and reduce on the carbon emissions.
