Scarcity of water resources is becoming an increasing challenging problem in the world. This calls for new means of water utilization, including seawater. Entropy generation has been implemented in designing a new device for desalination process based on nonequilibrium thermodynamics and interfacial/electro chemistry concepts. The efficiency of the new proposed device is almost twice of the previous apparatus proposed in the literature and therefore it is classified as a new generation membrane-free machines for the desalination process required for purification of the natural seawater used as drinking water and in related chemical and biological applications.
