Abstract

An earthen solar cooker (ESC) has been designed, constructed and tested. Simple and low cost compared to other solar cookers, it is made of a rectangular cavity dug out of the ground, covered with a glass plate. In a series of tests to investigate the feasibility of the ESC, one liter of water was used to simulate food. The temperatures of water and air in the cooker as well as outside ambient air were measured for 3-4 hours. For comparison purposes, a commercially available solar box cooker (SBC) was also tested side-by-side with the ESC. The results show that the ESC can potentially provide a favorable environment for cooking food and pasteurizing water. However, its performance is not as good as SBC's, mainly due to the lack of reflective surfaces in its design.
