Sun cloth and wind purification tank

The Sun Cloth and Wind purification tank is a very simple and affordable way of treating water. A lot of people exposed to unclean water in Africa have limited monetary resources. Therefore people can take advantage of the Sun Cloth and Wind purification tank that makes efficient use of two free abundant resources in Africa which are sunlight and wind energy. The dark plastic container mounted on a roof stand is an efficient ...more »

solar Atmospheric water generator

The system is based on the recovery of the moisture in the air passing through the fins of a cooled radiator. Cooling radiator is ensured by the compression / decompression of a gas through a Stirling engine solar free piston. The water recovered by a single radiator under normal conditions of African weather is on the order of 25 to 40 liters per day, this amount is doubled near the sea. The water quality even without ...more »

Environmentally friendly water transportation for rural areas

Developed countries are used to having a supply of fresh, clean water piped straight into their houses for their convenience. In some African countries, however, especially rural areas there isn't any provision for the supply of drinking water. Women and children take water from rivers or lakes and carry this back to their house, which is very labour-intensive. I'm not dealing with the supply of fresh, clean water here ...more »

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 »

Circulation Shower

We propose a circulation shower that saves 90% on water and energy. Families can shower endlessly with only a bucket of water. Our idea is to make an Africa-proof version of the circulation shower - a proven concept. This idea has already been deployed in the Netherlands and is ready to be deployed quickly on a large scale. By making circulation showers available to all families, schools and other public institutions, ...more »

Use of a Hamster Ball-Shaped Solarball

Designed by Jonathan Liow, a graduate student at Monash University, the Solar Ball is a spherical shaped device that utilizes the power of the sun to purify water. Inspired by a trip to Cambodia, Liow sought to aid underdeveloped populations that lack access to clean drinking water. When placed in the sun, the Solarball uses evaporation to separate dirt and contaminants. The resulting condensations yields just over three ...more »

solar powered borehole coupled with an ultrafilrer

This method involves the construction of a borehole with a pump that uses solar energy to power it. The pumped water is plunged upwards into a reservoir tank after passing through four ultra filters which are installed near the tank. A small tap connected to a pipe coming from the tank is used for easy access of the water. The ultrafilters ensure removal of disease causing pathogens before the water enters the tank. this ...more »

Aqua-Cura Mobile Water Sterilisation unit

Over the previous 3 years, we have developed a water sterilising unit that can destroy bacteria, viruses and hydro toxins, without the use of any chemicals. We then combined the steriliser with a filter that removes toxic metals from water. We have had extremely successful results that was analysed by WaterLab, an accredited SANAS lab. (Please note that this is not a reverse osmoses system). This combination was installed ...more »
