Trees draw carbon dioxide out of the air and forests are considered an important part of the global warming solution. But a scientist as Columbia University has an idea for artifical structures ("trees) that would be 1,000 times more potent.Sharon Vaknin at GreenTech reports:
"Klaus Lackner, a professor of geophysics at the university, has been working on the project since 1998, according to a CNN report, and is optimistic about a near-future application.
Modern improvements in coal-fired power plants have reduced carbon emissions, but Lackner is seeking a different function. The "tree" would be used to trap carbon that has already been emitted into the air by car gasoline or airplane fuel, CNN reports.

Unlike the real thing, the synthetic "tree" doesn't need direct sunlight, water, a trunk, or branches to function, as it looks more like a cylinder than a soaring Redwood. The concept, which Lackner says is flexible in size and can be placed nearly anywhere, works by collecting carbon dioxide on a sorbent, cleaning and pressurizing the gas, and releasing it. Similar to the way a sponge collects water, the sorbent would collect carbon dioxide." See full article.
