Here's a crazy idea I've been thinking for a long time. Is tthere a way to artificially create a way to trap sunlight and turn it into gasoline in an artificial process. Basically what earth does in thousands of years but with human ingenuity we make it a lot faster and free reproducible in other countries.
I see the core problem as. We already have great gasoline infrastructure. It's very energy dense. We just need to learn how to make green gasoline.
- abpavel 10y agoWe make a lot of green gasoline already. It's called biofuel. The problem is that it takes farmland away from producing food for people into producing food for cars. And cars are much hungrier, filling landscapes with rapeseed https://en.m.wikipedia.org/wiki/Rapeseed https://en.m.wikipedia.org/wiki/Rapeseed

The process works, it just takes a tremendous amount of energy (hence the nuclear carrier part) and it requires a lot of water to create a gallon of jet fuel (20,000 gallons I believe for a singe gallon of jet fuel). The toughest part, however, is that the process would release methane gas into the air. So it's unclear if it's really greenhouse-gas neutral. In theory, though, if you could trap the methane and then sequester the hydrocarbons you made, you'd have a way to pull CO2 out of the atmosphere.
