The army knows that its branches must reorganize their thinking on how to engage in the "theatre of war" in the new cold war of the 21st century world. One thing that the military leaders of the stress is the desire for the forces deployed in the theatre to be more independent of the energy. Currently, the US Army has policies and procedures in place to interact with allies or local populations sympathetic to help its forces in the field get their need of energy and water when committed in a foreign military campaign. However, this is not entirely reliable, as the United States could well find themselves facing unilateral military activities or have itself in a situation where its allies can help with resources as necessary to conduct its military actions with success.
The US Army is very interested in some alternative energy sources that, with good research and development from a technological perspective, can make independent, or much less much more energy on the battlefield. One of the things which greatly interested the military along these lines is the development of the small nuclear reactors, which could be portable, the local electricity of theatre. The army was impressed by combustion how clean nuclear reactors are and how energy efficient they are. Making them portable for the typical war of the armed forces highly mobile, small scale of operations today is something that they are research. More important than the US military believes that these small nuclear reactors would be useful to involve removal of hydrogen (fuel cell) of sea water. He also thinks that the conversion of water to hydrogen in this way would have less negative impact on the environment than its current practices of remaining provided by in the field.
Sea water is, in fact, the higher interest by the military when it comes to the issue of alternative energy supply. Sea water can be continually "used" for hydrogen, which in turn powers advanced fuel cells. Using the OTEC, sea water can also be continuously converted desalinated and drinking water. Drinking water and hydrogen for power are two of the things that a military force deployed near future it will be especially.
In the nuclei of nuclear reactors - which, as mentioned above are very interesting devices, as portable, US Army - we encounter temperatures above 1000 degrees Celsius. When this level of temperature is mixed with a thermochemical water-sharing procedure, we have on our hands the most effective way to break water into its components, which are oxygen and molecular hydrogen. Minerals and salts that are contained in sea water would have to retrieve via a process of desalination to make clear how the process of separation of the water. These could then be used, such as vitamins and salt shakers, or simply sent to the Ocean (recycling). Vehicles, using the power of nuclear reactors to extract hydrogen from the sea to entry in the fuel tanks advanced power cells, land-based aircraft and the like, is clearly high on the list of R & D priority military.
