Solar Ovens

Solar ovens are a low-tech, low-cost option to heating and cooking food. Similar to a crock pot, a solar oven is essentially a well-insulated portable box that captures and holds the sun's heat. There are a number of commercially available models and many do-it-yourself designs.

Solar ovens, once a quaint idea for an elementary science project, are making a comeback as a staple for emergency preparedness supplies and as an affordable convenience for low-income people in developing countries.
