I have the vision of hundreds of thousands of solar light concentrators used to produce energy and sweetwater. The lightconcentrators are ten feet off the ground to allow agriculture below. With the heated water are driven the sterling-generators to produce electricity, hydrogen and mechanical power. About a third of the surface is covered by these sunlight concentrators based on devirated fresnel lenses. A system of canals let the seawater to the concentrators and are simultanouly used as well to speed up the codensation of the water vaporated in many serial modules as the cooling of the sterlington motors. The earth would green up, man would have to eat and to live and the climate effect would slowly fade out. It could be that easy... My websites: Webdesign aus Düsseldorf
