The seawater desalination technique presented in this article is based on a new technique for the production of water vapor which has the advantage of using solar energy with maximum evaporation efficiency. This innovation is limited to the production of steam and can be combined with a known technique of condensation of the steam in order to complete the desalination cycle of seawater. This technique is based on the simple principle that the heat transferred from the hot source to the cold

... ce is maximum if the difference between their respective temperatures is kept at its maximum. Thus, by carrying out successive operations of heating thin layers of water, the technique makes it possible to maximize the efficiency of the evaporation by bringing the temperature of the fluid to its initial value at each iteration, thus enabling, according to the Newton's law, to favor the transfer of heat to water.Then, in this paper, we present the theoretical demonstration of the soundness of this technique by using the analogy with electricity using the equivalent resistance for circuits in parallel. Next, an application of the technique which is the subject of a patent of invention is presented in the detal. It is a desalination engine for seawater using solar radiation from a Fresnel concentrator. The presented invention makes it possible to produce steam continuously by heating thin layers of sea water by the Fresnel concentrator. The development prospects of the invention are also presented using the techniques of Nanotechnology.
