One of the main factors that led to this research on wind and solar energy hybrid application was the need to empower rural communities with communication technology, namely cellular phones which are now widely used in Zambia. A major constraint to the use of these devices in the rural areas is...

Zambia, like most developing countries, relies heavily on woodfuel as the major source of energy for cooking and heating. Over two thirds of the country’s population either dwell in areas that are very far away from the national grid or have not been electrified for reasons ranging from lack of...

In this work, a report is given of a centralized smart metering system intended to run an algorithm designed to address the problem of peak-hour energy deficit in Zambia. A survey study conducted in Lusaka to establish household power-usage patterns led to the development of the load-management...

Access to reliable and affordable energy is an essential input to sustainable development. Most of the rural communities in Zambia lack access to modern energy. Renewable energy technologies offer a solution to this. Through the help of various stakeholders, various renewable energy technologies...

The traditional high concentrating photovoltaic systems have proved to be expensive as they use high grade silicon solar cells, highly specular reflecting materials and require tracking arrangements which are equally expensive. The problem of un-even illumination creates heat-sinks which have not...

The production of energy from fossil fuels and nuclear materials has environmental drawbacks. These drawbacks include the creation of nuclear waste and the pollution associated with fossil fuels which lead to global warming and climate change. It is apparent that alternative and sustainable...

A high absorptance (>0.90) is an essential factor in the efficient use of a .solar collector. However, equally important is the need to keep the emittance as low as possible (<0.20). Both the.absoptance and emittance depend on the optical properties of the coating and the substrate. The solar...

The reduction of Masuku Cassiterite gravity concentrate by charcoal was investigated in the temperature range of 850 to 1100oC. A combination of sample weight loss measurements, exist gas analysis and chemical analysis of the reaction products was used to monitor the course of the reaction.The...

A numerical model for determining the size of a forced - convection solar fish dryer comprising of a drying bin (in which the fish is kept), aflat plate solar collector and a fan, has been developed. The model comprises of two sections with the first section calculating the technical parameters...
