There's always the air-gasoline route. That's right! With enough chemical engineering and materials science, we can extract jet fuel from air and water. You extract out CO2 from the air, and H2 from water. You turn the CO2 and hydrogen into carbon monoxide, and then Fischer-Tropsch chemistry and some other magic gets you hydrocarbons out the other end! The problem is the economics of that process can't compete with oil from the ground.

Even factoring in emissions?
Given oil from the ground is adding long buried CO2 to and steadily increasing atmospheric insulation whereas fuel-from-air is using what is already there.
Is this another example of discussions about oil not factoring in the negative externalities to make it look good?
