Submission + - Using Carbon Nanotubes to Capture Carbon Fumes (technologyreview.com)

TechRev_AL writes: A California start-up called Porifera is developing membranes containing carbon nanotubes to capture carbon dioxide from smokestacks more effectively. The membranes used to capture CO2 from smokestacks needbe selective, allowing carbon dioxide to pass through and not the other exhaust gases. This produces a concentrated stream of CO2 for capture. Porifera has found that carbon nanotubes are particular good at this--gases can move through the interior of nanotubes extremely quickly--at rates 100 times as fast as through conventional membrane materials.
