This process would be ideal for countries in the archipelago or those that are surrounded by bodies of water. However I think it would be a bit costly.

Awesome!!That's really a great idea to produce electricity from salty water.The process is explained so clearly and precisely.Great work!!

We must promote and apply the use of green energy. We promote Solar Powered Water Purification system, a systems turn polluted water from surface sources or from contaminated wells into safe, clean drinking water that powered by Solar Power that are not harmful to our environment. thank you for the post Author.

Consider the CO2 required for making activated charcoal/carbon and that this material will probably need replacing at regular intervals as well. Factor in pumping, filtration and the permits required for intake structures (impingement & entrainment) of biotic organisms in sensitive estuarine waters. Nuclear fusion starts to sound good right about now.

For every 1 cubic meter of fresh water mixing with 1 cubic meter of salt water (3.5% normal sea water), a theoretical maximum energy of 2 MW/cu. m per second is available. This energy will be low efficiency unless ionic membranes are utilized (see Marc Andelman´s patents-charge barriers), which would increase the cost. Just consider the pumping costs and filtration costs of that quantity of water before one chases the salination dream (many rivers unfortunately have high levels of sedimentation).

Very interesting idea.
I see two application for this:
1. Solar electric power generator.
The expose to sun light salt water will evaporate and then condensate the vapor as it is in conventional solar desalination, then the fresh water and salt water will be combine in the cell to produce electricity. Close loop system. I wonder what the efficiency will be.
2. Use fresh water, let say from rivers, as fuel for sea ships instead of bunker oil.
It is clean renewal energy driven by sun energy similar to wind power.

If this can generate power from mixing normal salt water and VERY salty water, could this be used for desalination? It takes power to separate fresh water from salt water (from the ocean), leaving behind extremely salty water. Mix this extremely salty water with normal salt water (again, in the ocean) to produce energy to power the separating of fresh water from salt water, and so on. Even if it only provided SOME of the power needed for desalination, it would help. One of the problems with desalination is that it produces very salty water that has to be dumped back in the ocean (not good for sea life). The other is that it requires power. Let one problem solve the other.

Logical first place to install this technology would be seaside water treatment facilities. They already reclaim methane from waste water and use it for energy production.

Since the power seems to come from a difference in salinity, it provides up yet another reason build a pipeline from the Red Sea or Mediterranean to the Dead Sea.
Some electricity would be generated from the 1100 foot fall from sea level to the Dead Sea, the lowest place on the surface of the earth. Additional power would come from mixing ordinary sea water with the extremely salty water of the Dead Sea. The two might make the project economically viable.
In addition, the salt water inflow would prevent the Dead Sea from drying out and the salt water that's brought it could be used for fish farms before being released into the Dead Sea. And in the end, this is a form of solar power, the energy ultimately coming from evaporation off the Dead Sea. It also wouldn't be complicated by the difficulties of building a power plant between a river and and ocean.
