On prediction of solar cooker performance and cooking in pyrex pots

Abstract Results of experiments conducted on the Arafa cookers that featured insulated receivers with Pyrex pots are presented. The utility of an absorption plate is described. A method is outlined whereby the performance curves of solar cooking are transformed into strainght lines. The resulting S -constants are utilized for the prediction of the time-temperature relationships of cookers operating at various levels of insolation for a given charge.
