> I am surprised all of the comments so far are so negative. They can take carbon out of the air and make jet fuel with it. We still need jet fuel. It makes flying carbon neutral.
This is either an oversimplification or the technology is not useful, since a naïve method of doing this means that you will have to put in the energy we got from burning the fuel to convert the carbon dioxide.

Gather $renewable energy for $x time (x > 8 hours), convert to high-energy-density fuel required for flight and burn for 8 hours to cross $continent... Seems useful to me!
