‘Solar’ jet fuel made out of air
Sweet.  Venus has a very dense CO2 atmosphere with negligible  amounts of oxygen and about twice the insolation of Earth.  Let's set up some high altitude blimps above the cloud layers as floating solar syngas factories.  I'm a little busy right now but in 10 years when Musk has the launch vehicles figured out I think we should do it.<p>Edit: I didn't type it because I thought it was obvious, but this would be producing fuel for rockets and other vehicles operating in exploration, not for bringing back to Earth to put in your car.
