    The nation of South Africa has long been the leading economic power of Sub-Saharan Africa. At the present day, the nation generates some 90% of its electric power from coal, including a recently built new generation clean coal power station rated at over 4,000MW of output. Some of South Africa's thermal power stations operate courtesy of advanced air-cooled condenser technology that originated in the research of Engineering Professor Kroger at Stellenbosch University, located near Cape Town. The quest to secure future electric power has led South African officials to engage in discussions with energy officials in both Congo and Ethiopia.

    Today, solar energy is synonymous with photoelectric cells. But there is a much simpler and cheaper way to use the sun's energy. Typically, three times as much energy falls on a building's surface as is used inside it. Molecularly designing the roof's surface to capture and control solar heat can supply one-sixth of the world's energy, as was shown in field tests by the European Union.
