The Rotatable Fish Drying Frame is aimed at formalising a specific fish-drying process already used by different communities in Africa. The frame allows for the drying of up to 100 kg of fresh fish at a time using the existing iteration. The key principle is that after one week of drying the drum

This technology involves a method for generating hydrogen in an electrolysis cell. A proton exchange membrane (PEM) is used to separate anode and cathode chambers of the cell. The space between the anode and the PEM is filled with aqueous sulfuric acid. In use, gaseous sulphur dioxide is fed to the

This process is used for generating hydrogen by providing a hydrogen chemical carrier in the presence of an active catalyst in a reactor vessel and elevating the temperature inside the reactor by electromagnetic process to allow a dehydrogenation reaction to generate hydrogen. The active catalyst is

The invention relates to a low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate-velocity wind and generate electricity efficiently for household use. Current large-scale wind turbines in South Africa are located far field and the energy generated must be transported

Postharvest table grapes are susceptible to fungal infection even when stored at the optimal temperature of −0.5°C. The most important pathogen of stored Table Grapes is grey mould, which is caused by Botrytis cinerea. Some countries fumigate their grapes with sulphur dioxide gas. However, if the

LeguPro is a protein-rich pasta, which is produced from non-traditional pasta ingredients such as peanuts, soybeans, and chickpeas. It is a cost-effective nutrient-dense high protein, healthy instant noodle product and aims to give consumers an alternative staple food product to be consumed as is or

The Agricultural Research Council - Vegetable and Ornamental Plants ( ARC-VOP), which has a solid reputation as a leader in sweet potato R&D, has developed a new variety Khumo orange-fleshed sweet potato. A 60-gram serving of boiled roots of variety Khumo, supplies the recommended daily allowance

Surfactants are amphipathic molecules with both hydrophilic and hydrophobic moieties that partition preferentially at the interface between fluid phases such as oil/water or air/water interfaces. Such characteristics confer excellent detergency, emulsifying, foaming, and dispersing traits, which

Currently, the ARC have three commercial cultivars, Ratel, Steenbok and Tredou. Ratel consists of a medium growth period whereas Steenbok consists of a short growth period with good drought tolerance making it suitable for areas with a dry climate. Tredou is the newest addition to the ARC cultivar

A method and apparatus for treating a fluid utilising nanoscience. The impurities in the fluid are trapped by the charged nanoparticles. The fluid is contained in a reactor that includes a moving magnetic system. When the reactor is in use, the moving magnetic system excites the charged

The invention relates to the use of maghemite nanoparticles at pH < 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In a conventional way of AMD treatment, these pollutants are only removed at higher pH and requires costly alkaline chemicals

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
