Patent number: 9861933Abstract: 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.Type: GrantFiled: August 22, 2016Date of Patent: January 9, 2018Assignee: CARBON SINK, INC.Inventors: Allen B. Wright, Klaus S. Lackner, Ursula Ginster

Patent number: 9616375Abstract: Disclosed is a method for removing carbon dioxide from a gas stream, comprising placing the gas stream in contact with a resin, wetting the resin with water, collecting water vapor and carbon dioxide from the resin, and separating the carbon dioxide from the water vapor. The resin may be placed in a chamber or a plurality of chambers connected in series wherein the first chamber contains resin that was first contacted by the gas, and each successive chamber contains resin which has been wetted and carbon dioxide collected from for a greater period of time than the previous chamber, and so on, until the last chamber. Secondary sorbents may be employed to further separate the carbon dioxide from the water vapor.Type: GrantFiled: January 24, 2014Date of Patent: April 11, 2017Assignee: Carbon Sink, Inc.Inventors: Allen B. Wright, Klaus S. Lackner, Ed Leon-Guerrero, Ursula Ginster, Tymothy Catterson, Karl Madison, Ryuhei Ishikawa, George W. Grimm, Mark Malcomson, Ping Liu
