SODIS Water Station

The SODIS method has been proven to be a simple and low cost method of purifying bacterial contaminated water in rural areas. My proposal here is to up-scale and streamline the SODIS method in the form of large water stations positioned at central locations within the communities. The entire system consists of the following 4 main points: 1. WATER COLLECT POINT: a floating weir is positioned in the lake or river where ...more »

SOLAR DISTILLATION

Not to be confused with solar sterilization or disinfection, solar distillation purifies even muddy, salty or otherwise undrinable water through evaporation and condensation. The power of distilation to purify saltwater makes it unique among the treatment methods featured on this page. A solar still can actually be a cheap and simple piece of shaped plastic or glass, or they can be more highly designed devices. To work, ...more »

The Sun-powered Water Well Solution

The main source of drinking water must be protected from deliberate pollution and spread of disease like guinea worm. The water is shared with animals, and is used by humans for cooking and drinking in the villages of Africa. Our solution to this program is to integrate a Sun-powered Water Well into the villages of Africa. This Water Well is eco-friendly and environmentally safe. As opposed to similar Merry-go-round ...more »

Solar Powered Ultraviolet water treatment Device

SOLAR POWERED ULTRAVIOLET WATER TREATMENT DEVICE Introduction Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV energy penetrates the outer membrane, passes through the cell body then disrupts DNA stopping reproduction. UV treatment does not ...more »

Elevated borehole Reservoir system

After discussions with a colleague with extensive experience in ground water research and borehole pumping projects, I learned that ground water extraction by means of solar powered borehole pumps have been proven quite successful in providing a considerable quantity of fairly clean, drinkable water to farms and rural communities. It is also a fairly simple system that works independently, requires little maintenance; ...more »

Artificial leaf makes clean energy from dirty water

If one day in the not too distant future you can go to the dollar store, buy a thin, flat device the size of a playing card, dunk it in a quart of dirty bath water and use it to generate about 100 watts of electricity 24 hours a day, you can thank the Air Force. Along with other federal agencies, the Air Force Office of Scientific Research has been pouring funds into the development of an “artificial leaf,” a low cost ...more »

Cheap Solar helical rotor pumps

We can very well see that there are some areas in Africa that has rivers but lack the means to connect these rivers for the use of its water in house holds and farms. This is because they lack electrical power to aid in the activity. Solar water systems use the power of the sun to drive a submersible electric pump and are ideal for boreholes with a high yield. The pumps I am setting on is the - helical rotor pumps - ...more »
