Create Your Own Solar Cooker 

 
SOLAR COOKING

You can cook almost anything with the sun and a "low tech" solar oven!
Homemade solar box cooker (you can make one of these out of plywood or even cardboard) These cookers can reach temperatures in excess of 300 f! This solar oven is constructed of a plywood box within a larger, outer plywood box. The space between the boxes is insulated with approx. 2" of "Perlite", the soil amendment gardeners use, although most people use regular fiberglass insulating material. (this was an experimental material that does work very well) The reflector is an ordinary glass mirror, however, aluminum foil or reflective mylar can be used just as effectively. Covering the oven is 1/4" tempered glass. Lining the inner walls is aluminum roofing type flashing. On the floor of the oven are two flat black cookie sheets with black barbecue type grills that the pots rest upon. The idea is to get the sunlight concentrated into the oven by orienting the box and tilting the reflector. The oven will then quickly heat up because the sun's heat energy is trapped under the glass cover. The black surfaces and the dark food containers absorb the heat. I use black porcelain steel pots, oven cooking bags, and various containers that have been painted black with barbeque paint.
