Why should I use the sun to cook?
The Sun:The sun, the Earth's star, is very hot and powerful. The core of the sun is approximately 15 million degrees Celsius and 4.5 pounds of sunlight hit the Earth every second!
More sun!All terrestrial and most aquatic plant life use the sun's energy to produce all their food. So why shouldn't humans? Renewable, Usable, Free Energy:
For many centuries, humans have been using fire as a source of fuel. Fire uses lots of wood to burn, and when wood was used african cooking pots photos in small enough quantities to allow time for new trees to grow in place of old ones, everything was great. Now, the demand for wood for other products, coupled with the increased population of the Earth is making wood for fuel scarce. Deforestation is a problem all over the World, especially in countries that depend on wood for fuel.

Our friend, the sun, is always there for us. Capturing energy from the sun is simply using energy that is currently not being used. It is also free to harness the suns power, an asset to anyone who pays electric bills. In regions of the World where there is no access to electricity or gas fuel, the benefits of solar power are tremendous.
How does solar cooking work?
Solar energy, in the form of light, can be reflected and effectively concentrated or focused into such a way that it can be used to cook food. The rays of light must be directed through panel positioning to focus on the place where food will be placed for cooking. This can be done through parabolic models that directly focus solar energy to a single point or through paneled models that direct the suns rays into a central location.This energy in the form of light must be converted into heat in order to be effective for cooking. Black pots, pans, and parts of the cooker are used as light absorbers. As the light is absorbed, it is converted to heat and transferred to the food, heating it to temperatures necessary for cooking, pasteurization and sterilization.
The heat energy must be retained within the cooker for a sufficient amount of time to be useful in raising and sustaining the temperature. Retention of heat is best done through insulation. Insulation involves absorbing and trapping heat. While this is mainly achieved through materials used in the construction of the cooker, (cardboard, adobe, concrete, hay, or trapped air), type of cooking device can also affect efficiency.For additional information on this topic:

How do I build my own solar cooker?
In order to build a solar cooker for ordinary use the following items will be needed:
Reflective surface material: Aluminum, tin, mirror, glass, etc.
Cooking Utensils: For faster cooking paint pots black (if not otherwise so).
Insulation: Adobe, tire (rubber), soil, ash, cardboard, trapped air, etc.
Container: Cardboard box, baskets, wood, etc.
Plans for each of the following designs can be accessed by clicking on the headings below. For further examples and designs an extensive list of plans for building solar cookers has been compiled by. The following are the three main styles that have been developed and implemented in the field:

Where have solar cookers been used?
These women stand next to their panel cookers in Burkina Faso A Kenyan woman bicycles home with the solar cooker she has just completed. The box type solar cooker here carried by three African women, was easily constructed with cardboard.
These three men are fashioning their own parabolic panel out of clay.
The box cookers seen here in Tanzania were made out wood.
This basket was woven especially for the purpose of being made into a solar cooker.

This modified box-style solar cooker was built by while she served as a in Paraguay. Newspaper was used as insulation, and a hole dug into the ground for use as an outside box. In this picture a cake is being baked.
