Abstract:
This thesis investigates the application of solar water heating in South Africa. The solar water heating system investigated work on the thermosiphoning effect or natural convection. An extensive literature study has been undertaken to investigate this phenomena. The three partial differential equations (governing equations) are non-dimensionalized and a similarity solution is applied to obtain two coupled non-linear ordinary differential equations. These equations are then solved in MATLAB to obtain the velocity and temperature profiles. Two scenarios were considered, a vertical wall with a c

Abstract:
Life is not easy for the low-income rural population of Southern Africa. This includes those living in the informal settlements around cities. It is in part due to shortcomings in basic services such as water, sanitation and electricity. More than half of the households are without running water. One of the day-to-day problems is gathering and carting sufficient water for domestic use from communal water sources. The water is often of dubious quality, and waterborne pathogens cause a range of bacterial, viral and parasitic diseases. Children and people with compromised immunities are especiall

Apart from all being renewable and sustainable, each of the renewable energy sources has its specific characteristics and advantages that make it well suited for specific applications and locations. Solar photovoltaic and wind turbines are well established and are currently the mostly used renewable energy sources for electricity generation in

Abstract:
Increased standards of living and indoor comfort demands have led to an increase in the demand for air-conditioning in buildings in South Africa. Conventional vapor compression systems use refrigerants that damage the ozone layer and contribute significantly to the global warming effect. Therefore, there is an urgent need to implement environmentally cleaner ways of satisfying this air-conditioning demand and absorption cooling systems have shown great potential to do so. This project is concerned with finding the technical and economic effectiveness of solar powered absorption cooling systems

Abstract:
Studies undertaken by Eskom in 2001 identified three sites near the Northern Cape town of Upington which are suitable for a 100 MW Concentrating Solar Power (CSP) generating plant. Of the CSP technologies investigated, the central receiver option was identified as best for the Northern Cape, however almost none of Eskom’s analysis was made public. The basis of the central receiver’s suitability versus other CSP options is not publicly known. Given recent advances in concentrating systems, an argument exists for reassessing the suitability of various solar thermal technologies for bulk power ge

Abstract:
M. Tech. Architectural Technology<br>South Africans are faced with the challenge of becoming less dependent on fossil-based electricity (which is very commonly used in the heating of homes), because it is not only becoming less affordable, but also less sustainable. Wood-burning fireplaces have developed over thousands of years, and an analysis thereof reveals that a correctly designed and constructed wood-burning masonry fireplace is a valid alternative to electrical heaters. The research design consists of a survey of existing wood-burning masonry fireplaces and chimneys in South Africa. Thi

Their simplicity, however, belies their potential to make a major contribution to the reduction of greenhouse gas emissions as well as stimulate local markets and macroeconomies. Solar water heaters have many benefits, they empower individuals and nations to contribute to environmental protection, save the homeowner money and create employment and skills development.

Abstract:
Vapour pressure (interchangeably referred to as atmospheric humidity) and solar radiation data are, for different reasons, difficult data to obtain in South Africa. Relative humidity measuring instruments (from which vapour pressure values can be obtained) require constant maintenance , while solar radiation can only be measured electronically. Data from both of these variables are, however, required as inputs to the Penman-Monteith equation, which has become the internationally accepted reference for the estimation of potential evaporation. It is necessary, therefore, to produce estimates of
