The engineering of making kerosene from air, water and solar is mind boggling. The problem is CO2 at 400ppm means the volume of air needing to be filtered is just vast. Using the finest current technology (Carbon Engineering ltd) just to remove the 2019 commercial aircraft emission, about a giga ton of CO2, requires an air intake 8m high, and 5000km long. To power the air induction alone would require 60% of entire electrical energy generated in the USA, and that’s before the CO2 is separated from the air, split up, the H2 is separated from the water and the Kerosene is synthesised.
Just who’s gonna pay for this?
Apologies for the grim facts.
