Interesting proposition.
1. Why would your process be more cost effective and/or efficient than the commercially available processes for alcohol production?
Surely if the magic sauce is the nanotube alcohol/water separation then conventional alcohol sources from fermentation will start using it at some point and will be able to produce same fuel but cheaper and/or more efficient.
Maybe you can show that [photosynthesis -> organic matter -> fermentation] is less efficient than your process using renewables as input?
2. Why use CO2 from Air?
At 400ppm, there is 500 times less CO2 in air than in any powerplant exhaust, so using the same state of the art separation, for the same throughput, your equipment should be ~500 larger? That seems like a capex waste.
