At any rate, amazing product. Can I (eventually) buy one of those machines or donate somewhere to make my area CO2 free?
Edit: Or close enough to perpetual motion that it only requires the occasional replacement of nanotubes and other materials
An oil pump can pump enough oil to fuel itself (we don't need solar to power our gasoline industry). And we can eat a plant and have enough energy to cultivate more plants to eat. I would not be surprised if it works the same here.
Edit: I guess the flaw in the logic is that, where there is a lot of energy stored in oil and plants (and plants get it from soil and the sun or so, again something external), this process is the reverse of burning. So if reverse burning costs less fuel than burning, we'd have a perpetuum mobile. Is that it? I'm sorry that this wasn't immediately obvious to me (if that is even the answer), since there are so many other fuel creating and self supporting processes...
