Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies. These problems are related to navigation, recreation, irrigation and hydropower generation. The complete

The invention relates to the design of a robust membrane for desalination using membrane distillation (MD). Although MD technology has advanced over the years, its industrial application for the treatment of brackish water and seawater is still lagging. This invention exhibits advantages over the

A system which harvests thermal energy from various sources such as sunlight, cars, power plants, factories and other industries, and converts it into electricity. The harvested heat energy is stored in a storage tank, with water used as an energy storage medium. This then flows along a gradient to

The technology is capable of treating high-temperature wastewater as a membrane for removing oil from wastewater One of the key challenges with membrane filtration devices is the issue of fouling and concentration gradient build-up on the surface of the membrane, which subsequently decreases its

Hydrogen and fuel cell technologies offer zero emissions and are a clean alternative to fossil fuels. HySA Systems, at the University of the Western Cape, have made improvements in the performance, reliability and cost competitiveness of fuel cell components and systems. These have been demonstrated
