Abstract

Solar box cookers are simple. But they are real, functioning appliances that can be made of many different things depend on our requirements or needs. Solar cookers are perfect example of appropriate technology. There are many NGO's and other groups worldwide now designing, constructing and using these simple, elegant and effective devices. A solar box cooker is designed, constructed and tested at Universiti Malaysia Sarawak (UNIMAS) as my "Projek Tahun Akhir". The solar box cooker is tested by using 3 different setups or methods. Various design changes were examined. Results show the advantages of double glazing and black absorption plates in the base of the cooker. The optimum combination of these changes resulted in an increase of 88% in cooking power compared to the basic design. Cooking temperatures of 87.5°C were reached within two hour. These temperatures and heating rates allow practical cooking of many foods. Solar cookers are also can be use to dye clothes, sterilize medical supplies, stored/dry food and even soil.
