A method and apparatus for extracting CO 2 from air comprising an anion exchange material formed in a matrix exposed to a flow of the air, and for delivering that extracted CO 2 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 CO 2 to greenhouses where increased levels of CO 2 will improve conditions for growth. Alternatively, the CO 2 is fed to an algae culture. |
