Wind energy and solar power water purifier: looking for partners in Spain, Portugal, Greece

Several are places in constant need for drinking water, especially isolated places, rural areas or small islandic territories only to mention a few. The system patented by an Italian inventor includes a prism structure, consisting of a plurality of slabs (glass or plastic material, but also of photovoltaic panels or other materials), hermetically connected, leaving open the lower surface which is immersed in the water so that it can enter into the prism autonomously. The prism is anchored to a support structure permanently fixed to the bottom of the basin. The facility, hermetically closed by the slabs and water at the lower side, becomes an “assisted solar furnace”. Inside the prism, placed just immediately below the water surface, there are electrical resistors powered by the renewable source (wind turbine, etc) associated with the system. Those resistors, combined with the energy collected from the irradiation of the sun, have the function to heat (about 20° to about 100 °C) and bring quickly to boil the water surface inside the prism. The steam thus generated is then conveyed, by convective motions, into a separate reservoir placed below sea level, in which, due to the reduced temperature, the steam condensates and turns into purified water. The liquid thus obtained can be transferred and then be used. The water produced at the end of the process is desalted and suitable for pharmaceutical or other industrial uses. After further cheap remineralisation processes, the water can become drinkable. The system is cost-effective and efficient. The inventor estimated the yield and the energy needs compared to a module of about 5 m of side: placed in the Mediterranean environment, the system, associated with 8 MW wind turbine, with 6 hours of sunshine per day could produce more than 100 m³ of water. The inventor is interested in finding an industrial partner to license the patent and start commercialize the product derived.
