First off most plants evolved in an environment where CO2 levels ranged from 2,000 to 5,000 ppm. Current levels represent plant starvation and require more water uptake. Second. No mention of the economics let alone how you will exchange an exhaust heated collection box at refueling time. The real answer is more wind, more solar (when it is cost effective) and fusion power plants. Search - Bussard Fusion - to see what some possibilities are for small fusion plants. The Bussard design produces very few neutrons if fueled by Boron 11. If we are going to go to an all electric car or even bio-fueled plug in hybrids we are going to nead a lot more electricity quick. I don't like fission power because of the plutonium problem.

An interesting piece about the power of human ingenuity. It raised a few questions the piece didn't answer like: will this work for smokestack emissions? or, is it really feasible for motorists or gas station attendants to swap these boxes out every time we fill our tanks? and, what if somebody doesn't fill up every time? Still, I'm looking forward to reading more on an invention that could revolutionize how we react to the critical problem of global warming

Doesn't present the perspectives of any skeptics.

Reminds me of the cold fusion stories. If it seems too good to be true, it probably is...
