Solar oven or solar cooker is a cooking device that uses sunlight as an energy source. Because this type of stove do not use conventional fuel and operating costs low, humanitarian organizations are promoting their use worldwide to help slow deforestation and desertification, caused by the use of wood as fuel for cooking.
Solar cookers can be used outdoors, especially in situations where minimal fuel consumption or fire risk becomes an important consideration.
There are different types of solar cookers. Everything uses heat and light from the sun to cook food. Some basic principles of solar cookers are as follows:
1. Concentration of sunlight. Some devices, usually a mirror or similar material metal that reflects light, is used to concentrate the sun's light and heat toward the cooking area is small, making the energy more concentrated and more potentially generate enough heat to cook.
2. Convert light into heat. The interior of the solar cookers and pans, of any material from the black, can increase the effectiveness of turning light into heat. A black pan will absorb almost all sunlight and convert it into heat, substantially improving the effectiveness of the cooker. The better ability to deliver hot pot, the faster the stove and oven work.
3. Trapping heat. Efforts to isolate the air inside the cooker from the air outside will be important. Use of hard and transparent material such as plastic bags or cover the pan made of glass allow light to enter into a saucepan. After the light is absorbed and turned into heat, plastic bag or cover made of glass will trap the heat in it such as the greenhouse effect. This allows the stove to reach the same temperature as cold and windy day as when the day sunny and hot.
Strategy heating a thing by using solar energy becomes less effective if only using one of the principles mentioned above. In general, a solar cooker using at least two ways, or even three basic principles of solar cookers to produce temperatures sufficient for cooking.
Apart from the need for sunlight and needs to place the solar cooker in the right position before use, the stove is not much different from the conventional stove. However, one disadvantage is that solar cookers are generally cook food on a hot day, when people tend to be reluctant to eat hot food. However, the use of thick pot that delivers heat slowly (such as pots of cast iron / cast) can reduce heat loss rate and by combining with the use of thermal insulation, stove to keep warm the food until the evening.
Closing stove can usually be opened to place the pot into it. Box cookers generally have one or more reflective than aluminum foil material or other reflective material to reflect more light into the interior of the box. Cooking pot and the inside bottom of the cooker should be dark colored or black. Inner walls of the stove should be able to reflect light to reduce heat loss and direct reflected light toward the pot and stove, dark basic, direct contact with the pan.
