I heard about machinery to convert atmospheric CO2 to fuel that is workable now but not quite cost effective. I don’t know that because I did not see it in print, just heard it on the Coast to Coast from a weather guy who is not an AGW believer.C2C has some interesting and real guests, physicists like Michio Kaku, on sometimes. Mostly it is “spiritual” hogwash, though.
Obviously I am one of the latter, also an engineer, and I keep up with the trade rags that talk about the actual real technology not the theoretical stuff that still needs to he scaled 5 orders of magnitude. I also happen to believe that too much CO2 is just as bad as too little. We are not close to having too much and the technology will catch up as the need arises. Some basic R&D is still needed, and a big helping of capitalism.
