There are three types of solar cookers, solar box cookers or oven solar cookers, indirect solar cookers, and Concentrating solar cookers [2-10]. Figure 1 shows different types of solar cookers namely. A common solar box cooker consists of an insulated box with a transparent glass or plastic cover that allows solar radiation to pass through.

There are three common types of solar cookers which are; (1) concentrating solar cookers, (2) box solar cookers, and (3) panel solar cookers. An appealing solar cooker must be user friendly, locally available at an affordable price, and must be able to reach high cooking temperatures in a short period of time. Concentrating solar cookers are .

The literature on solar cookers is very limited and has focused mainly on household solar cookers, while solar cookers for institutional applications have been ignored. This study contributes carried by comparing application levels type of solar cooker. This paper presents a short review on different types of solar cookers.

"solar panel cooker" that can reach temperatures of between 120 and 150 C for cooking, roasting or boiling. It should be noted that there are other types of solar cookers that can reach higher tempera-tures for frying or grilling food. 1.1 Types of solar cookers There are three different types of solar cookers:

limited the use of solar cookers in Mozambique, as discussed by Otte [10]. To overcome some of the limitations of direct solar cookers, a thermal storage is essential in the solar system. Solar heat can then be collected while the sun is available and stored for later use. So, a solar stove with heat storage, which has a potential to enable

Basic Methods of Solar Water Pasteurization-Solar Cookers A simple method of pasteurizing water is to simply put blackened containers of water in a solar cooker.3 There are many types of solar cookers, but a solar box cooker is sketched in Fig. 1.

and need treatment even without any contact with solar cookers. I only want to mention that albinos, who not rare in Africa, should not come close to solar cookers, because they lack protective pigment in the skin and eyes. 2.1 Infrared and visible light The IR part of the spectrum is further divided as follows: IR-A: von 780 nm bis 1400 nm

new cooking technology we are working with is called Insulated Solar Electric Cookers, or ISECs. These cookers are very efficient. At LEF, we use solar power, and that makes us 100% energy self sufficient at the residential level. But unlike other off-grid projects, 90% of our electricity never goes through a battery.

atmosphere because solar cookers concentrate a large amount of light to a relatively smaller absorbing surface. The area that sunlight is collected from is called the aperture area. Before how solar cookers concentrate light is discussed, the law of reflection must first be understood.

Fortunately, Djibouti possess ample amount of solar radiation and this offers solar cooking as one of the most attractive options. Solar cookers have a long history dating back almost to 18th century. According to B. Halacy and C. Halacy [2], the first experiments on solar cookers were carried out by a German Physicist named Tschirnhausen (1651-

A SOLAR COOKING DAY The day opens bright without much cloud. So, it is time to take the covers off the solar cookers at about 8.30 a.m. The kids are very keen to volunteer for the job because mom has promised them something special today. The aluminum covers are, in fact, all-weather covers that protect the solar box cookers from rain and

One alternative to cooking with wood is using solar cookers. These devices use energy from the sun to cook food without producing any pollution. While there are many designs for solar cookers, a simple solar cooker can be made from everyday materials. There are many factors that can influence the effectiveness of a solar cooker including the

Even if only 5 percent of persons facing fuel shortages in the year 2005 use solar ovens, roughly 16.8 million tons of firewood will be .

Keywords—Solar Box Cookers, Reflectors, Insulation, Vessels, Storing heat, Testing 1.

that, kerosene oven, Solar over with box type, and solar oven with parabolical shape. Seven brands of solar ovens were tested [6]. 66 families were involved in this study. The most utilized cookers were solar, wood stoves, and open fires. The percentage of using a solar oven for all days was 38%, and for cooking meals was 35%.

Solar cooking takes less time than gathering wood, peat, dung or other traditional fuels. Solar cooking can help keep family members safe in areas where collecting firewood or fuel can be dangerous. Solar cooked food is healthier. Solar cookers can be used to pasteurize water. 3.

A 'solar cooker' is a device which uses the energy of direct sunlight to heat for cooking purpose. Lots of designs of solar cookers currently available in use are costlier. Commercial solar cookers are costlier since made from high grade materials which a common man cannot afford. To overcome this problem low cost eco-friendly

HOW SOLAR COOKERS WORK Fuel: sunlight Sunlight is the fuel. A solar cooker needs an outdoor spot that is sunny for several hours. Solar cookers don't work at night or on cloudy days. Convert sunlight to heat energy Dark surfaces get very hot in sunlight. Food cooks best in black pots with tight lids to capture the heat. Retain heat
