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.
Working principle View to the East from the parabola center One of the 63 heliostats. The principle used is the concentration of rays by reflecting mirrors (9,600 of them). The solar rays are picked up by a first set of steerable mirrors located on the slope, and then sent to a second series of mirrors (the concentrators), placed in a parabola and eventually converging on a circular target, 40 ...
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.

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.
Scheffler cooker at JNV school in Leh, India.. Wolfgang Scheffler (born 1956) is the inventor/promoter of Scheffler Reflectors, large, flexible parabolic reflecting dishes that concentrate sunlight for solar cooking in community kitchens, bakeries, and in the world's first solar-powered crematorium.

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 ...
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]
A modified version of SG3 was exported to Ben-Gurion National Solar Energy Center at the Ben Gurion University in Israel. In 2006, a joint project led by the Solar Thermal Group with commercial partner Wizard Power, and funding from Australian's Government's Renewable Energy Development Initiative, [3] began the design and construction of SG4 .
