Sketch of two researchers

We are two major environmental researchers who is interested on the various environmental problems.
We put our knowledge for the benefit of the poor as the southern hemisphere countries which know a lot of problems. One approach we enable to found that there was huge problem with drinking water. That's why we try to build a system to desalinate seawater. Our next challenge will be to solve the problems of famine.

THE ABSTRACT :

Targets of the technical study: - to invent an economical system which uses the solar energy in order to desalinate water - to optimize our system - to be able to desalinate about 1 litre per hour - a simple and cheap construction

Context of the study:

Nowadays we are trying to economize more and more energy. The use of solar energy for production of drinking water is a priority for many countries because the desalination of salted water through ordinary distillation is more expensive operation because it requires a lot of energy.
For poor countries in energy and drinking water resources, solar desalination of salted water becomes an economical and social development stake.

System chosen: Systems with cylindro-parabolic reflector

The cylindro-parabolic reflectors are systems in a "U" shape. The cylindrical reflectors concentrate the sun rays on a glass receiver tube located along the focal line of the reflector.
