Parabolic solar cookers concentrate sunlight to a single point. When this point is focused on the bottom of a pot, it can heat the pot quickly to very high temperatures which can often be comparable with the temperatures achieved in gas and charcoal grills. The highly reflective parabolic shape has the property of bringing parallel rays of light (such as sunlight) to a central focal point. If the axis of symmetry(Center of parabola) is aimed at the sun, any object that is located at the focus receives highly concentrated sunlight, and therefore becomes very hot. This is the basis for the use of this kind of reflector for solar cooking.
Because it uses only concentrated sunlight, it requires no additional fuel source and is a completely renewable cooking solution that produces no greenhouse emissions at all. SunFire Solar Cookers have a lifespan of 5 to 10 years, and can save an enormous amount of emissions and lives in its use. The reflective coating loses its properties after 8-10 years, once replaced your SunFire Solar Cooker will be as good as new. This is a product you can leave to your grandchildren.
Foil replacement can costs as little as R200.00 ZAR.

Sunbags or retained heat bags allow you save eb=ven more time and money.
Simply Cook your meal 50% of the way, pop the pot in the retained heat bag and wait for it to finish Cooking. Yes it really works…!!!
The Sunbag allows you to turn your Solar Cooker into a Two plate stoves, effectively doubling your Cooking capacity. We estimated that when these 3 appliances are combined, cooking fuel costs can be reduced by
The Health, nutrition and Environmental benefits are staggering.
