Navy is looking to use seawater as fuel...
US Navy: Converting Seawater Into Fuel a 'Game-Changer' | Defense News | defensenews.com
The Navy is researching using seawater to power their ships and planes. |
I think we have the solution to the rising sea levels!

Chlorine?

While converting seawater to fuel is feasible, this is bordering on fodder for the Unicorn Corral, especially in the quotes from the Navy personnel.
1st Rule of Fight Club, er, Thermodynamics is that energy cannot be created. I think it's a safe bet that these "reactor systems" require a large input of energy (electricity?). I don't believe for a moment that they will be able to use this to create fuel without some outside source of energy. Now, if they use it to fuel planes that take off from a nuclear powered ship, sure I can see that being useful. |
I'm with darcane. This just sounds wrong. I can see the dissolved CO2, but where is the hydrogen coming from? I'm not aware that there is dissolved H2 in water that can be extracted. And even then, there appears to be a process that requires the input of energy.
Al in all, this sounds like a less than zero sum game. |
I just had the visual of a f-14 with a fish bowl style HHO system zip tied to the rudder

It is.

Electricity is needed along with catalysts to power the reaction and the equipment. This has been doable in the lab for decades. The unique part of the NRL application is the use of certain catalysts that provide long chain (C7 and above) output instead of the usual methane. This allows for a possible drop in fuel for diesel and JP-8. The electricity is problematical, but not overly so if you allow a unit compact enough to be placed on a nuclear powered ship with an abundance of excess electrical output or in-theater where an electrical grid is available. The wild-ass-guesstimate of 6-8 dollars a gallon is the point of the exercise. Providing fuel to front line units and protecting that fuel all along the supply chain becomes very expensive. 60-80 dollars a gallon are numbers I have heard thrown around for JP-8 to the front. In some theaters, that number can hit 120 dollars a gallon. Providing fuel in theater cuts your costs dramatically even at $10 a gallon pricing. And, it provides you with greater security. Looking forward, the technology can be widely applied to consumer markets when nuclear power-plants become common. The ability to turn excess electricity into liquid fuel during off peak hours will be invaluable. Here is more discussion from Green Car Congress: http://www.greencarcongress.com/2014...0408-navy.html And a link to the NRL download of the 2010 paper: http://www.greencarcongress.com/2014...0408-navy.html |

As I read it, the rest of the article implies that ships will produce the fuel needed to power themselves. And I'm sorry, that is not going to happen. |
