Science ComedicBlade August 8, 2016 1 0
A new way of cooking, cooking is using solar heat. Especially in countries where it is difficult to get fuel for cooking this is an ideal way of preparing food. There is cooked in a kind of box or kit, which is coated with aluminum foil or is provided with mirrors. By putting these boxes in the sun, the food inside is cooked.


It was the Swiss researcher Horace de Saussure who designed the first solar cooker in 1767. Nowadays, it is possible to easily and safely with the help of to be able to cook the sun. Thanks to the new development in the field of solar cookers.
The solar cooker can be divided into three types:
  • cooking boxes
  • reflector tubes
  • collector tubes

  • Cook Boxes

    Affordable, safe, simple design and ease of use, which is the cooking box. It is an isolated kit. The interior is black and it is covered with glass or transparent foil. A mirror on the lid of the box provides for the cooking of box extra sunlight.
    A disadvantage of cooking in this way is that it takes quite a long time before the food is cooked. The mirror and the glass are very fragile and to stir by eating the coffin to be opened, whereby heat is lost. One advantage is that large quantities of food are equal ready.

    Reflector cooker

    This pan is quite expensive to buy. This sunlight is concentrated directly onto the pan. This allows the cooking times are shorter. The pan gets hotter, so even baking, frying and sterilization is possible.
    We are working on developments that cool with this pan also an opportunity will be.

    Collector Sleeves

    With this method of cooking is a collector heated. This condition, in turn, the heat to the pan. This pan can store the heat, so cooked at a different time can
    be. It takes a long time food is ready and this pan is quite expensive. Also, for the preparation of large quantities of this pan is not entirely suitable.

    Where to use

    Actually, this way of cooking wherever sunlight is applied. In the refugee camps, it is quite ideal; Here the fuel is very scarce. The people are stripped of their traditional habits and in this way its a great opportunity offered to them to prepare their meals. In the Kakuma refugee camp in Kenya is a solar cooker program asset that has been very successful, according to the UNHCR. The Refugee Foundation is supporting a similar project in Nepal.
    Also, areas where fuel can not itself be collected, but is to be purchased may be the introduction of this method of cooking to be a success.

    Solar cooker Testing

    Conducted by the ECSCR is an international test. Tested 25 solar cookers from eight different countries, SK / 14 came as one of the best performers.

    The SK-14

    This solar cooker is a reflector sleeve, and in the last 10 years developed by Dr. Ing. D. Seifert. The parabolic mirror with a diameter of 1.4 meters focuses the sunlight on the matte black pan. Within 18 minutes there is 2 liters of water brought to the boil.
    Many disadvantages of this method of cooking have been obviated, as is more practically no danger of burning and glare. The cooker can be used from one hour after sunrise and one hour before sunset.
    The pan has been designed so that the design can be adapted to materials and techniques in a particular country or area are easily at hand. The most expensive of the solar cooker's reflector. This is made from specially processed and highly durable polished aluminum strips. The SK-14 is among others produced in local workshops in:
    • Ecuador
    • Peru
    • Argentina
    • Uganda
    • Nepal

    This tube is sold with the organization DSW and the price for a kit form completed tube is about ?? 200, -

    The CooKit

    Developed by the French professor Professor Bernard. Solar Cooking International has taken up the idea for further development. The CooKit is made of simple materials, weighs about 7 ounces and folds. It is a simple cardboard box which is covered with aluminum foil. It takes about two to three hours before most of the dishes are done.

    The CooKit in Chad

    Every morning put the women in the desert CooKit in the correct position. Then every half hour, the kit a bit with the sun helped out. The cooking time will be extended by fifteen minutes when a cloud appears in the sky.
    In include Burkina Faso, Kenya, Mali and Chad, there is a special holiday for cooking with the CooKit arise ?? Id el Tachashumshir ??, or Feast of the Solar Cooking.

    The CooKit in Netherlands

    In itself, the CooKit or to use in the Netherlands. On days when the sun is shining continuously can be achieved a temperature between 100 and 150 degrees. This temperature is sufficient for the preparation of a stew of meat, chicken, fish, rice, beans, or a dried cake. Cooking will take a 2x long as cooking gas. As long as there is sunlight for 20 minutes per hour, there is no problem. In changeable weather is cooking in this way not recommended.
