Imagine this! It is feasible, but you would basically turn nuclear power into electricity then produce the jet fuel from seawater at $3-$6/gallon. Considering that it costs more than $10/gallon to deliver the fuel, this would be nice. At least this is carbon neutral. They can also generate electricity from temperature difference of the deep and the surface of the ocean. This can be extended to other applications. Details of technology is partially revealed below:
U.S. Navy Uses Seawater to Make Jet Fuel on the Go
September 26, 2012 By Tina Casey
Imagine a fighting force that can scavenge its own fuel as it marches along, and you’re either thinking about the Continental Army’s march to Yorktown or the U.S. Navy not too many years in the future. Scientists at the Naval Research Laboratory (NRL) in Washington are working on a process that can produce jet fuel from seawater. It sounds like something that would give the U.S. a powerful edge in action, so let’s call this Round 3 in the Navy’s efforts to free itself from dependency on fossil fuels.
