Time scale is also something I want to know about. "Can I remove CO2 from the air and turn it into something valuable in a way that is cost effective?" is one question. Another question is, "Can I remove CO2 from the air and turn it into something valuable faster than a tree?"

My guess is that it would be much more effective to capture and remove CO2 directly at the source, for example at a cement plant. While this could be done at a fossil fuel plant as well, it seems a lot less attractive: you give back most of the energy you just got from burning the fuel.
