Power by Sea Water

When we think of vehicles running on water we think of  hydrogen engines, well there is another way.
The Navy researchers at the U.S. Naval Research Laboratory have another way.

They have come up with a way to convert sea water into a liquid hydrocarbon fuel. The proof of concept has taken place by flying a replica of a World War II P-51 Mustang with the fuel.

The  hydrocarbon fuel can be extracted with a 92% efficiency rate bring the cost of fuel the fleet down to a predicted $3-$6 per us Gallon. If ships could be fitted with a convert to do this on board then no refuelling would be required giving greater sea time at reduced cost.
