U.S. Navy Has Found A Way To Turn Seawater Into Fuel

I follow, I'd seen something about a newer process someone hadninvemted, I'd wondered if that might've been a derivative of it, maybe not, didn't know, just wondered...

Sadly, I believe it takes more energy to crack the hydrogen/oxygen bond than the energy you derive from cracking it. If it didn't, you would have a perpetual motion machine

CPT Jack Durish - We do it on Nuclear Submarines all the time. Distill the sea water, then use the distilled water in our O2 Generators, then keep the oxygen and pump the hydrogen overboard. No reason why the Hydrogen could not be bottled/containerized and used as fuel, depending on the type engines on a specific Navy platform in use.

MCPO Roger Collins - Granted, H collected as a byproduct of another process wouldn't "cost" anything. However, two issues come to mind: (1) You are using energy generated by a nuclear plant to crack the H-O bond to produce O2 needed for breathing Surface ships that are not nuclear propelled don't have such a power source to crack the H-O bond. Where will that energy come from? (2) Surface ships don't need to produce 02 for breathing.

The total today is about 160. The United States is the main navy with nuclear-powered aircraft carriers (10), while Russia has nuclear-powered cruisers. ... Congress has mandated that the U.S. Navy consider nuclear power as an option on all large surface combatants (cruisers, destroyers) and amphibious assault ships.

LOL, yeah, one would hope, I'd suppose...
