Seawater could be used to fuel up US Navy's ships after they vowed to cut their petroleum use in half by 2015, reveal scientists.

Willauer said that the non-petroleum fuel, which would cost between 3-dollar and 6-dollar per gallon to produce, is comparable to current prices of petroleum fuel.
If the desired results are achieved by the researchers, the petroleum alternative could turn out to be a boon for the Navy in terms of its alternative energy goals, and it would provide a faster and safer process of refueling, that is usually costly, time-consuming and a risky process, to its expanding fleet.
