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
The technology relates to an upright tubular fixed-bed reactor body comprising a heat -dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Ficher-Tropsch, which are prone to heat build-up. The heat pipe is
This invention relates to a system that continuously measures and monitors the dynamic behaviour of turbomachine blades in order to provide early warning of incipient blade failure. This would enable management to take corrective action in order to prevent failure and downtime. The system can be
This invention relates to an alternate oxidant for a delay composition, and more particularly to a delay composition including a fuel and an oxidant in the form of antimony hexitatridecoxide having the formula Sb6O13. The invention also relates to the use of antimony hexitatridecoxides as an oxidant
A cost-effective, highly efficacious trough assembly for collecting and removing drops with minimal air-side pressure drops for use in evaporative heat exchangers or cooling towers. The innovation reduces water consumption and required fan power. The elimination of a rain zone reduces the required

SUNSPOT is a solar thermal power plant with rock-bed storage, containing a unique set of patented and individually licensable Stellenbosch University technologies. The SUNSPOT cycle is appropriate and efficient for generating, storing and deploying solar power in arid regions.

A cost-effective tip appendage design that reduces tip leakage vortices in axial flow fans to improve fan performance. The appendage is robust in that it is applicable to various axial flow fan designs and can be installed on currently operational units through retrofitting due to its simplistic
Power plant efficiency is generally determined by projected electricity tariffs and power plant life cycle costs during the design phase. This technology can be installed below wet cooling tower fills to significantly enhance the thermal performance of the cooling towers, resulting in a reduction in
This technology uses Unmanned Aerial Vehicles (UAVs) fitted with a camera to calibrate heliostats in large Concentrating Solar Power (CSP) or Concentrating Solar Thermal (CST) tower systems. The UAV does not have a single fixed position and provides several advantages over traditional methods using
The inverse Class-F power amplifier (PA) comprises an appropriately biased GaN active device, input matching network, and output wave-shaping and matching network. The novel design of the wave-shaping and output matching network ensures minimal overlap of the drain voltage and current waveforms, and

The Solar Tracker has been developed at the Cape Peninsula University of Technology. It is an efficient mechanism for positioning a solar collector to track the sun. This device is adept to intermittent adjustment of the position of a solar energy collection surface, ensuring that the surface
