Dear David Keith, Thank you for the response. I enjoyed your TED presentation a while back. I'll certainly read the literature you linked. A couple of quick questions...
Say, all these AC groups (and others) are provided with unlimited funding tomorrow and the problem of what to do with the captured carbon is sorted out... 1. How quickly could we deploy air capture on large scale? 2. What do you forsee the cost per tonne of CO2 capture to be in such a scenario?
