Whoa, gasoline produces 20 pounds of CO2 per gallon burned. So 100 gallons per ton of CO2. At $2/gallon, that's $200/t to produce. And then we have to spend potentially more than that to clean up the pollution. Planetarily, we iz a stupid.

But for the record, I absolutely don't believe it's that cheap to take CO2 out of the air at scale. So this whole thing is a pipedream.
