How to Make a Solar Oven

Learn how to make a solar oven that works beautifully, is built to last, and costs less than a purchased solar cooker.

Sun rays reflect off the foil sides and are concentrated at the base of the cooker, where they are absorbed by the black pot. The glass cover (or clear oven cooking bag) helps hold heat and moisture in the pot. The cooker should face the sun. Raise or lower the box depending on the time of year so that you can catch the sun straight on. Shim the wire rack as needed to keep the pot level.
