Projects: Cooking With the Sun
You can cook using the sun’s free energy! There are many plans and designs for solar ovens/cookers (listed below in related links).
A sun oven can be built using simple, household materials. The ovens are safe and easy to use. Just place your food in the oven, point towards the sun and, in a couple of hours, you’ll have a hot meal.
The oven can cook and warm many meals: rice, beans, soups, bread, cookies, cakes... you name it! This oven offers clean efficient energy without using any of the earth’s resources or polluting the air.
HOMEMADE SOLAR OVEN
The Answer Comes Up Every Morning....
Photo One: Here are the side panels of the inner box. We used pieces of 1/2 inch plywood, then framed the outside with 1x2’s. On the inner side we took metal cookie trays and screwed them to the plywood.
Photo Two: This view is the backside of ‘Photo One’. We joined the panels with screws, then cut Styrofoam (recycled from packing material) and glued them inside the frame.
Photo Three: The outer box is made from 3/4 inch plywood. We painted the entire outside with flat black paint.
Photo Four: After we had connected the panels of the inner box together, we placed it inside the outer box. We then stuffed Styrofoam down the sides and bottoms of the two boxes. Note: the floor of the inner box is made from aluminum sheeting glued to plywood and attached to the inner box. The bottom was placed on 2x2 blocks with Styrofoam placed underneath it.
Photo Five: This is one of the 4 panels of the sun collector. It is made from aluminum sheets glued to 1/8 inch particle board; the other side is painted.
Photo Six: The solar cooker top is made from two 1/8 inch plywood. Before we glued them together, each plywood had squares cut out of them. The bottom piece had a smaller square cut out while the top one had a larger one. When glued together, it provided a lip that the oven door (2 double paned glass pieces fitted into a frame), could close onto. Small hinges were used to attach the door to the top edge of the cooker. The top was then attached to the main box with screws.
Photo Seven: The sun-collector panels were attached to the solar cooker with braces bent at a 67 degree angle. The panels were bolted to the braces that were screwed into the main box. Note: The front panel was attached with wing nuts, allowing for easy access to the door. We also cut small panels to fit in the side gaps. They were attached to the main panels with little pieces of plastic as hinges and small bolts. This formed a complete sun collector around the oven.

When I was a scoutmaster we had the boys make ovens out of cardboard boxes. Lined with aluminum foil. used a surface thermometer for temp. Used a couple bricks to hold up the grate. In a small pan we placed 4 lumps of charcoal. The boys baked cake and other items. Baked food on a campout can be done without a dutch oven. But a dutch oven is the most versitile.
