Description of technology
A solar cooker, or solar oven, is a device which uses the energy of sunlight to heat food or drink to cook it or sterilize it.
The three most common types of solar cookers are box cookers, curved concentrators (parabolics) and panel cookers.
Box cookers
Box cookers cook food at moderate to high temperatures and often accommodate multiple pots. Worldwide, they are the most widespread.
Parabolic cookers
Curved concentrator cookers, or "parabolics," cook fast at high temperatures, but require frequent adjustment and supervision for safe operation.
Panel cookers
Panel cookers incorporate elements of box and curved concentrator cookers. They are simple and relatively inexpensive to buy or produce.
