Solar Oven Designs - The Different Types Of Solar Oven Designs Available
For several decades various solar oven designs have typically been used in third world regions where electricity or other fuel sources are hard to find. Solar cookers have been used effectively in sunny African countries like Sudan to not only cook food, but also for water purification and pasteurization.
But just because first world countries have enough energy supplies, it does not excuse us from using solar cooking at home and helping to conserve that energy. What's great about solar cooking is that it uses the power of the sun to cook food - though it may take 4 times longer than a conventional oven.
Over time many solar oven designs have been mastered, but they generally fall into three main categories: parabolic solar cookers, panel cookers, and box cookers.
Parabolic Design:
A parabolic solar cooker, as the name implies, is made from any reflective material in a parabolic (bowl like) shape that focuses sunlight to a single point. It is the most effective at cooking food quickly and efficiently, however, it tends to be more expensive and hard to make by hand. Furthermore, its fixed shape makes it less portable and raises some safety concerns.
Panel Cooker:
Similar to the parabolic design, the panel design focuses sunlight to a single point. However, it is less rounded and made up of a number of small, flat, reflective panels.
The panel shape is not as efficient as the parabolic shape, but it has the advantage of being foldaway, portable, and rather simple to make. These cookers can be found in a number of interesting deigns, but the simplest is by far the one made by folding one of those reflective windscreen blinds.
Box Cooker:
Very different to the other two designs, the box cooker works by trapping the sun's heat, instead of simply focusing it on a central point. It is designed in such a way that it let's light in, but stops that heat from escaping. As more sunlight comes in, the hotter it gets.
This results in the entire area of the box to get hot and be able to cook larger portions of food at a time. This design is by far the simplest to put together - all you need is a black cardboard box with one side covered in tin foil and a sheet of clear perspex or glass on top to hold in the heat.
What's great about most solar oven designs is that they can be built from everyday materials in a few short hours. Like a conventional oven or stove, they can be used to prepare anything - such as roasted meat, steamed vegetables, rice, fried eggs, and baked bread. And since a solar cooker is used outside, it will not heat up the kitchen and place stress on your cooling system.
And if you think that over 75% of American households use their oven or stove on a daily basis - a tremendous amount of energy could be conserved if more of us used solar oven designs during summer.
So get started cooking with solar today. There are a number of commercially available solar cookers on the market. Alternatively you can make your own at home by searching online, where a variety of free solar oven designs with full building instructions are provided.
