Method and apparatus for extracting carbon dioxide from air
First Claim
1. An apparatus for the capture of CO2 from air comprising an anion exchange material that captures CO2 from a flow of air and from which captured CO2 is releasable by wetting or a swing in humidity;
- and a wetting or humidity source contained within an enclosure containing a growing biomass, wherein the anion exchange material is a movable filter that is moveable into and out of the enclosure.

Abstract
A method and apparatus for extracting CO2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO2 to 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 CO2 to greenhouses where increased levels of CO2 will improve conditions for growth. Alternatively, the CO2 is fed to an algae culture.
