Interestingly, if we add an offset tax to gasoline it'd only be 30 cents a gallon for inefficient capture (a lot, politically, but not harsher than living in your house for a year). With newer capture technologies it could be closer to 4 cents a gallon, which is less than the price difference between gas stations. The second-order effects are that once you build thousands of these capture stations there's huge financial upside to making them even better. Tax actually seems very feasible.
