Capturing Carbon

This video from NOVA scienceNOW explains how geophysicist Klaus Lackner and two engineers, Allen and Burton Wright, teamed up to develop a technology to capture an important greenhouse gas, carbon dioxide (CO2), in the air. Modeling their design after a tree—and one of Lackner's daughter's science experiments—the team tested different materials, configurations, and coatings that together would act as leaves do to remove CO2 from the air. However, instead of mimicking photosynthesis, their process uses a manufactured fabric that attracts CO2 and pulls it out of the air for subsequent storage.
