Slant faced solar oven from cardboard boxes
August 9, 2007
After building several smaller ovens from cardboard boxes and cooked with great success, I decided I wanted something bigger so I could cook a whole meal, including dessert in one oven. This one reaches well over 225 degrees once heated up for an hour before food is put in, then stays consistently at 200 until food is baked. This oven has 2 inch space between the two boxes and insulated with newspapers.
The inside is lined with heavy duty aluminum foil, glued to the walls and floor, a black metal roasting pan tray is on the floor, with metal racks, and several 1/4 inch thick ceramic tile painted flat black with non toxic paint are leaned up against the back wall, to provide stored heat when a cloud comes through and blocks the sunlight.
Anytime the sun is out, and no threat of rain, I put several ovens out to preheat and begin baking breads, bisquits, cakes, casseroles, meats as the day progresses. This saves on electricity in the summer not having to heat up a kitchen to cook food.
There really is no need to pay several hundred dollars on a solar oven when you can easily build a good one, many times, for less than a meal, costing 5 bucks.
All you need is several cardboard boxes, one bigger than the other, some aluminum foil, cheap school glue, and black acrylic, tempura paint, or non toxic when dry flat black BBQ paint, and large oven turkey bags.
You can build panel cookers that fold up and be taken with you to go camping without messing with fires if the weather is sunny.
But, you must be patient cause it is slower cooking since the temps are lower, but its well worth the effort.
