a solar oven

A solar oven or solar cooker is a way of harnessing the sun's power to cook food. A metal box forms the simplest solar oven. A set of large mirrors or a large Fresnel lens to focus sunlight to a single point may also be added. On a sunny day a black baking tray or cooking pot can convert thousands of watts of light into heat, in addition to any infra-red. Temperatures in a typical oven can reach 200°C (400 degrees F).

Diffusion of innovations theory, discussed in the book of the same name by Everett Rogers, discusses adoption of solar ovens in Lesotho. Although solar ovens were safer and cheaper to use than oil burning ovens, Lesotho women resisted using them. Agencies such as the Peace Corps have tried to use "change agents" to influence the women. But these change agents have differed from the women in class and norms and were not effective in spurring change. Researchers have found that the diffusion process works better if the change agent trains a local aide who belongs to local social networks and can better influence locals.
