Here are five models of homemade solar cookers.
On either end are reflector-type, with the left being also a parabolic. The three in the center are box-type ovens.
Notice the dogs? They were more interested in the tantilizing aroma of a solar-cooking meatloaf than the shade.

 

 

 

 

 

 
satellite dish cooker One can even use (recycle) an old satellite dish. The shape of the dish will determine the parabolic angle which will in turn determine the focal point (where you put the cooking pot). You may have to adjust distances accordingly. The dish used here measured 24" x 22" and its focal point was 18" from the dish. Use a wide focal area for cooking. A pinpoint might melt your pot.

 

 

 

 

 
Cakes, chicken, meatloafs,and even fish cook easily at 160 degrees. This oven reaches 250 degrees, so be sure to check food regularly. Box-type cookers can come in a variety of shapes to better use available sunlight. cake and meatloaf
