TREE AND SHRUBSLeaf it to me

Why aren’t geo-physicist Klaus Lackner’s Artificial Trees being “planted?

It seemed like a good Idea..I can’t believe that something so laim as carbon dioxide emissions from cars can be responsible for so much damage and yet nothing be done…

Massachusetts Institute of Technology engineer Howard Herzog thinks Dr Lackner’s design will not hold together on the scale he proposes.

He said you would expend more energy in capturing the CO2 – in keeping the slats coated in absorbent and disposing of it – than you would save.

“Once the solvent captures the CO2, it holds it on tight,” said Dr Herzog, “and it’s going to take a lot of energy to break those bonds.”

He said that much more research was needed on the technology.

“The idea of air capture is seductive and would really be great to have,” said Dr Herzog, “but it’s important to separate out the concept from the technical details.”
