How'd you like to have one of these in your yard?
Mechanical Co2 Filteration "Trees" are an interesting answer to our pollution problems. I never would have thought to "build a better tree" to combat those issues. And as Kert Davies of Greenpeace said, (it's) "like taking NyQuil for pneumonia."
Columbia University geophysics professor Klaus Lackner has invented what he calls "atmosphere scrubbers": 300-foot-tall steel posts bearing giant air filters that chemically simulate photosynthesis. These "trees" can remove CO2 from the atmosphere a thousand times faster than natural trees -- 90,000 tons a year, the emissions equivalent of 15,000 cars.
I agree with the Green activists on this gripe: The invention would prolong the use of polluting fuels and delay the shift to cleaner, greener energy sources like wind and solar. It will take decades to wean humanity off its fossil-fuel addiction, he reasons, and global warming could wreak havoc much sooner.
I'm not sure I'm ready to have one of these in my yard, but at least it'll keep the cats out of the trees!
