You missed the part where I said “make hydrocarbon fuels [em]from CO2[/em].” If the fuel you’re burning is made from CO2 that you just pulled out of the air, you’ve got a closed loop with no net emissions. The overall effect is no different than if you were using electric vehicles.

Other advantages: no need to wait for sufficiently good batteries. No need to convince people to replace their cars with new ones that take hours to “refuel” instead of minutes. No need to retool the car companies or build a bunch of recharging stations. Just install new stuff at the refineries and you’re good to go.

Overall energy efficiency is lower, but with FF that’s less of a concern.

In any case, I think that’s the case we should make. If electric cars turn out to be more competitive after all, then fine.
