European chemists claim to have demonstrated the feasibility of generating jet fuel (kerosene) from concentrated sunlight, carbon dioxide, and water. See the article in Chemistry World for details.
So ... we take a greenhouse gas - CO2 - and water plus sunlight and viola, jet fuel/hydrocarbons. Is this a way to have unlimited supplies of something formerly available only from fossil sources? It sure sounds like it. The question, of course, is whether it can be done at a reasonable cost.
