Abstract

A method and apparatus for extracting COfrom air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted COto controlled environments. The present invention contemplates the extraction of CO2 from air using conventional extraction methods or by using one of the extraction methods disclosed; e.g., humidity swing or electro dialysis. The present invention also provides delivery of the COto greenhouses where increased levels of COwill improve conditions for growth. Alternatively, the COis fed to an algae culture.
