what is solar furnace about 500 words
Answers
Answer:
A solar furnace is a structure that uses concentrated solar power to produce high temperatures, usually for industry. Parabolic mirrors or heliostats concentrate light(Insolation) onto a focal point. The temperature at the focal point may reach 3,500 °C (6,330 °F), and this heat can be used to generate electricity, melt steel, make hydrogen fuel or nanomaterials.
The largest solar furnace is at Odeillo in the Pyrénées-Orientales in France, opened in 1970. It employs an array of plane mirrors to gather sunlight, reflecting it onto a larger curved mirror.

History
Edit
The ancient Greek / Latin term heliocaminus literally means "solar furnace" and refers to a glass-enclosed sunroom intentionally designed to become hotter than the outside air temperature.[1]
During the Second Punic War (218–202 BC), the Greek scientist Archimedes is said to have repelled the attacking Roman ships by setting them on fire with a "burning glass" that may have been an array of mirrors. An experiment to test this theory was carried out by a group at the Massachusetts Institute of Technology in 2005. It concluded that although the theory was sound for stationary objects, the mirrors would not likely have been able to concentrate sufficient solar energy to set a ship on fire under battle conditions.[2]
The first modern solar furnace is believed to have been built in France in 1949 by Professor Félix Trombe. It is now still in place at Mont Louis, near Odeillo. The Pyrenees were chosen as the site because the area experiences clear skies up to 300 days a year.[3]
Another solar furnace was built in Uzbekistan as a part of a Soviet Union "Sun" Complex Research Facility impulsed by Academician S.A. Asimov.[4
