I am intrigued by the idea but find the details hidden in the Faraday reactor and separation nanotube membrane to be hard to sanity check / the most important factor that is not well understood. (or at least, I don't understand it / have not read enough) What's the magical material in the Faraday reactor that can somehow combine CO2 + water to form hexanol? I've never heard of such a process occurring (again, probably my ignorance). And then similar question for the separation filter? If I had to guess an analogy, it strikes me as similar to mining and then recovering + refining miniscule fractions of uranium isotopes at a similar energy cost. And when you require that much energy/cost to get some small amount of material, it had better be very valuable, and not something you just burn at $3/gallon. But I am glad to be educated on how this is breaking that analogy.
