This technology provides a method for making a nanofluid by nuclear irradiating a mixture of a base fluid and precursor to form the nanofluid. Nanofluids exhibit superior thermal properties such as enhanced thermal conductivity, viscosity, heat transfer coefficient, dielectric strength, etc. However
The technology relates to a sol-gel based, uniform carbon-coating method for producing high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce uniformly carbon-coated lithium-ion batteries that overcome the challenges of

The technology relates to an upright tubular fixed-bed reactor body comprising of a heat-dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Fischer-Tropsch, which are prone to heat build-up. The heat pipe

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 renewable energy powered street light which provides off-grid lighting. Powered by a combination system of a vertical axis wind turbine, a solar panel, and a rechargeable battery system. Twerly™ uses a vertical axis wind turbine (VAWT) to harvest wind energy and a standard 140W photovoltaic (PV)

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
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
