CO2 only accounts for 0.04% of the atmosphere, guess you need to concentrate or isolate it before pump into your solution, also gas solubility in water is low,

CO2 only accounts for 0.04% of the atmosphere, guess you need to concentrate or isolate it before pump into your solution, also gas solubility in water is low, so you might need to reduce temperature or change air pressure to increase CO2 solubility. I just read Haber-Bosch process today, looks like your process could be similar. You mentioned use nanotube to extract alcohol, is this process similar to chromatography? Do your nanotube's half-life long and stable, and the production now is in industrial scale and low-cost?
