The author needs to go back and take 7th grade science again. This process does NOT remove CO2 from the air, it removes if from lithium carbonate. The amount of CO2 in the air stays exactly the same. In addition, the energy to liberate the carbon requires more burning of fossil fuels than is “captured”. Why not simply use the carbon in coal? Besides all that, the mass of useful nanotubes is trivial compared with the mass of CO2 the Global Warming religious zealots want removed.
“mass of useful nanotubes is trivial compared with the mass of CO2 the Global Warming religious zealots want removed.”
I made the same comment before reading yours. See #34.
