Randy Atkins: Carbon dioxide would be plucked from within your car's exhaust system, or a factory smokestack, by a new chemical engineered in Omar Yaghi's lab at UCLA.

Omar Yaghi: It's simple to make, using cheap starting materials.

Randy Atkins: Yaghi says the crystal's framework traps CO2 specifically, using the shape of its openings and electric charge.

Omar Yaghi: They're strong enough to hold the carbon dioxide in the reservoir, but weak enough to be able to remove carbon dioxide later so that you can reuse the material to capture more carbon dioxide.

Randy Atkins: Yaghi says collected CO2 could be pumped underground and permanently sealed away in natural geologic formations.  With the National Academy of Engineering, Randy Atkins, 103.5 FM, WTOP Radio.
