I am talking about hydrocarbon fuel made out of carbon dioxide captured directly from air, which makes it possible to kill two birds with one stone: to get rid of the CO2 that so many of us love to hate, and second, to make fuel that is environmentally-friendly as it is not obtained from oil but from one of the greenhouse gases.
