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 »
H2O Solar tank tank is a solar powered water purifying tank. It is made of two portions of tanks one on the upper and one on the lower part. It is a portable tank with two wheels and it can be pushed or pulled with ease. The tank is equipped with an ultra violet light and semi permeable membrane. H2O Solar tank also have a solar powered water pump.
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 »
The pain and sufferings of 345 million in Africa and 743 in world has kicked off us to gear up latent humanity to start-up the social development project to bring back and sustain the smiling face of affected people. Safedrop is an innovative & Eco-friendly partnership enterprise that delivers Solar Water Pasteurizer to ensure safe drinking water from surface water replacing the contaminated water at affordable rate which ...more »
we can build big dams and drill wells with sustainable rain catchment/sand filtration system that runs and is controlled by solar powered equipment that can purify and pump out gallons of water to the needy.
where i stay we have alot of sunshine all year round but grappled with a problem of accessing clean water. But research has shown that we have alot of water underground water. The only problem is of how to access it but the means are available in todays developed world. what is needed is drilling it from the ground and pumping it out of the ground using a solar water pump. some filters and storage facilities with a capacity ...more »
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 »
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 »
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 »
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 »
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 »
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 »
