I sort of wandered in from the Science Fiction Forum before anyone could stop me. I have a thought that I simply lack the expertise to make use of, and I thought I would drop it in the laps of people who do have the expertise to make use of it. What would be involved to pull carbon directly from the atmosphere and turn it into a substance of commercial value (say, automobile frames & bodies)? Plants, after all, do this at room temperature. The reason I have this thought is that, rather than trying to solve global warming through regulation, it makes more sense to solve the problem through appealing to the greed of my fellow primates. Better to harness all that ingenuity into the pursuit of a buck than squander same ingenuity figuring out ways to get around regulations. I suppose I'll be looking for replies, but I'm far more interested in getting you people to talk to each other than to me. Thank anyone who reads this for there time.
