** The solar cooker is a cooking device that utilises sunlight as its source of energy. Solar cookers are used in situations where fuel is limited, as they need no fuel to work and cost nothing to use. Recently these cookers have been promoted by humanitarian organisations, to stop people cutting down trees for fire wood. These solar cookers are often used when cooking outdoors in situations where minimum fuel consumption is of high importance. A simple solar cooker can achieve temperatures of around 150° C (300° F), but food will cook as long as the temperature gets up to about 90° C (200° F). There are several different types of solar cooker including, Solar cookers are just one aspect of the every growing area of alternative energy. The solar cooker is a good design as it is accessible to a lot of people in LEDCs and MEDCs. They can be built using local everyday materials or bought ready made. They can be used to cook anything from steamed vegetables to roasted meat. Anything that can be done in a conventional oven can also be cooked in a solar cooker. If everyone prepared their hot meals using a solar oven the CO2 output would be significantly lowered. Solar cookers can also be used to pasteurise water. In third world countries this has significantly lowered cases of hepititus, gloucoma and guinea worm. A big challenge facing the solar cooker is people acceptance of the change. It is a dramatic change in the way people cook and could be difficult to get people to accept. The point at which the cooker is most powerful is the point when the sun reaches its hottest during the day. People may be less inclined to eat a hot meal at mid-day. The solar cookers take longer to cook a meal than a conventional oven, therefore people may have to wait an hour or two before the meal is ready to eat. Dull weather makes it difficult to used the cookers as there is not a strong enough source of light to heat the cooker.
