Parabolic solar cookers essentially concentrates sunlight from the dish to a central point where a pot or a pan can be placed. The heat is immediate as soon as the dish is focused to the Sun, and it is comparable to gas or fire.
Free cooking with the Sun.
The parabolic solar cooker is an extraordinary appliance that provides totally free energy using only sunlight. It uses the same principle as a magnifying glass on a bigger scale, and this allows you to cook as if you were using your gas plate or oven-top at home. This unit will boil a liter of water in approximately 4 minutes.
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 (Centre 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 and upon replacement, the cooker will function as normal.

Quirky side-effect include getting more cellphone reception if you stand in the right spot – luckily not the same as the cooking point which can be handy in remote areas but not something we can “sell as a feature”.
Another free extra benefit is placing a candle in the focal point, you’ll be amazed at how much light you actually get, a great garden ornament or free spotlight.
