Interesting idea. I wonder if you could increase the efficiency/speed massively by injection pure CO2 and water, rather than harvesting from the air. Combine this with a carbon capture system, even make a closed loop powerplant that burns the gas, and captures the CO2.
The basic system could be handy in remote locations, though it doesn't really say how much equipment would be needed per litre of fuel made per day, or whatever.
