edit this page Sunstoves in the Republic of South Africa by Dr. T.B. Scheffler At the Transvaal Provincial Administration's Witvinger Nature Reserve, six different types of solar cookers from various parts of the world were tested under practical conditions, and several types were built. It was found that not a single model could compete with Sunstove for user acceptance. At the Department of Physics of the University of Pretoria we are privileged to be able to further improve the Sunstove - which is already the world's best. Aspects being investigated are aimed at:
- increasing the thermal performance without increasing the cost.
- making the unit even more user friendly.
- making it suited to further applications.
- developing suitable black pots and other accessories.
The Sunstove initiative came from Mr Richard C Wareham, Milwaukee, Wl - an American with long-time strong links to South Africa. Since 1992 he has designed and sponsored several models which have been manufactured and marketed The manufacture has been in Springs, RSA. The most thermally efficient solar cooker is probably of the vacuum tube type, which retails at several hundred dollars.
