What, like make stuff out of thin air? We’re already there! Get this – there’s a group of guys of in Doncaster who have hooked up a solar panel array to the roof of a shipping container and they’re using chemistry (and a lot of electricity) to make petrol out of THIN AIR. They’re extracting the carbon dioxide and water out of the air and using it to synthesise petrol. It’s a contained unit, and they don’t make a lot of it (something like a couple of litres a day) but you could put that anywhere in the world and it would work. Genius.
