Abstract: | This paper reports on a three-year programme to establish whether solar desalination is a viable technology for use in remote settlements in Botswana, where provision of water is the number one problem facing the people. The Rural Industries Innovation Centre at Kanye in Botswana has, since 1977, been experimenting with solar and other types of wood-burning stills with the view of adapting this particular technology for local use. The paper reports on the use of solar and wood-burning stills in remote areas of Kgalagadi District. In this district a three-year field research project was set up in October 1984 in order to conduct technical and socioeconomic research on the suitability of prototype solar stills for remote area dwellers. The conclusion is that solar desalination is an appropriate technology for some remote areas of Botswana. The brick solar stills showed a more even output throughout the year. Their production dropped by 50 percent in winter as opposed to 60 percent in the Mexican stills (made of fibreglass). Bibliogr. |
