Sun Cooking is the Best Practice in Indonesia

The considerations on how the oven chamber, the aperture area and the mirror reflector area of solar box cooker were designed are described. A model of evaluation, which uses the oven temperature information has been derived, so that the cooker performance can be derived without involving the uncertainty about the heat capacity of the cooker interiors. It is also used to conform the effect of design change on the performance. This paper reviews a concept in design technology that is combined with a dissemination mechanism through a community education and the societal background why sun cooking is needed. A preliminary test of concentrator cooker K10 is briefly described.
