The Externally-charged Capacitive Mixing principle

The Figure shows the principle lay-out of the external charging process. First (figure A) the capacitor is charged in sea water as explained before. This is done via an external power source and the capacitor is loaded until a certain potential has built up. If this charged capacitor is then brought into contact with the fresh water solution (figure B), the potential of the capacitor rises as a result of the expansion of the double layer. The capacitor is then discharged and energy can be harnessed. This process needs in the first step an input of electrical energy but in the second step more energy is gained due to the increased potential.


Principle of energy generation via the externally-charged capacitive mixing process.
Picture A shows the external charging process in sea water, while picture B shows the energy generating discharge in fresh water.

After the electrodes have been discharged in fresh water, they can be charged again
in sea water. Overall there is thus a transport of salt from sea water to fresh water, i.e. mixing has occurred.
