Parabolic Solar Cooker. A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, [1] and advanced, large scale solar cookers can cook for hundreds of people.

The solar furnace at Odeillo in the Pyrénées-Orientales in France can reach temperatures of 3,500 °C (6,330 °F). A solar furnace is a structure that uses concentrated solar power to produce high temperatures, usually for industry. Parabolic mirrors or heliostats concentrate light onto a focal point.
A parabolic trough is shaped as a parabola in the x-y plane, but is linear in the z direction. A parabolic trough is made of a number of solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length up to 15 metres (49 ft 3 in) or more.

Solar cookers use sunlight for cooking, drying and pasteurization. Solar cooking offsets fuel costs, reduces demand for fuel or firewood, and improves air quality by reducing or removing a source of smoke. The simplest type of solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated ...
The solar furnace of Uzbekistan was built in 1981, and is located 45 kilometers away from Tashkent city. The furnace is the largest in Asia. It uses a curved mirror, or an array of mirrors, acting as a parabolic reflector, which can reach temperatures of up to 3,000 degrees Celsius. The solar furnace of Uzbekistan can be visited by the general ...
Solar cookers are being used by hundreds of thousands of people throughout the world. Solar cookers can also pasteurize or sterilize water to provide safe drinking water without using or collecting firewood. Kyoto Box is based on the original "Hot box" solar cooker, invented by De Sasseur in 1767. [citation needed]
