jet fuel from sea water

While entering some local gasoline prices at ashevillegasprices.com, I ran across the following article in the sidebar: "Navy Turns Sea Water Into Jet Fuel."

This sounds absolutely fascinating; combining CO2 with hydrogen to produce long-chain hydrocarbons for fuel. I loved chemistry in school, but never knew that this process was a possibility. Hope it works.

There is plenty of CO2 and hydrogen to be had. Even if the fuel doesn't end up cheaper than fossil hydrocarbons, the raw materials are far more abundant than oil reserves.

Thinking further down the road, it seems likely that this line of research could enable interplanetary spacecraft refuel on another planet, moon or asteroid using locally available raw materials. Not necessarily water, of course, though that is present in large quantities in a few places around our solar system.
