Producing Renewable Liquid Fuels from Atmospheric Carbon Dioxide

In summary, the US Navy has a process to extract CO2 from seawater and use electricity generated by the nuclear power plant to produce kerosene for aircraft.

I think Vonnegut weathers a lot better than Groucho Marx.

I guess reading my link was too much to ask, so here’s a picture:

The atmospheric pressure was the same. The fraction of oxygen in the atmosphere was closer to 30% than the current 20%. This is well-established geologically.

There is definitely some upper limit to stable atmospheric oxygen proportion, whatever it happens to be.

There has to be a difference between the energy required to lock CO2 away, chemically and producing a fuel with it. I realize it's an attractive idea to combine the two functions in one process but feasibility must be an issue
