The key to motivating a capitalist nation to participate in carbon capture is to first discover a way to profit off of the captured carbon.

That’s simple enough, create a process where CO2 is removed from the air and turned into oil. The chemistry of the individual steps is already known and achievable, the hard part is the energy input required to make it work.

Edit: Okay so I typed the reply and then went and read the paper. Turns out that what I described is kinda-sorta what they’ve done, although it’s certainly not a finished or industrially viable process at this point.

This is a bit of an issue when what they want out of the oil is the energy. If you have enough energy to make oil, why not just use the energy directly?

the one vaguely sensible use case is as portable fuel, but then it raises questions such as “why do we still have combustion cars” and “don’t cars actually kinda suck? shouldn’t we be running more trains instead?”
