SOLAR COOKING

Solar Cookers use sunshine as a source of heat for cooking
as an alternative to fire.
A solar box cooker traps the sun's energy in an insulated
box; such boxes have been successfully used for cooking,
pasteurization and fruit canning. Solar cooking is helping
many developing countries, both reducing the demands for
local firewood and maintaining a cleaner breathing
environment for the cooks.
The first known western solar oven is attributed to Horace
de Saussure in 1767, which impressed Sir John Herschel
enough to build one for cooking meals on his astronomical
expedition to the Cape of Good Hope in Africa in 1830.
Today, there are many different designs in use around the
world.
