Design of a Solar Water Distiller Based on Frugal Considerations

Abstract

The paper focuses on technologies for purifying unsafe water. Based on the analysis of existing purifiers, a new distiller is proposed for a domestic usage. A prototype is described and tested aiming at the validation of the concept. Then, a dysfunctional analysis highlights recommendations for its improvements. A second version is proposed to fix the failures by taking into account frugal considerations for developing countries. The frugal aspects give objectives in terms of recycled materials and give advices to simplify the maintenance of the product. A discussion is finally engaged to define the advantages and the limits of the second prototype, in terms of technical performances and based on frugal considerations.
