What is a solar furnace?

Sun furnace is any device that creates heat by concentrating sunlight using reflectors. A small solar furnace can be used to cook food without consuming firewood, while a larger solar furnace can produce electricity by heating gas. There have been attempts to introduce this technology to developing countries in order to minimize deforestation related to firewood, but only with limited success. Take two mirrors, direct them to focus and the intensity of sunlight in this focus will increase approximately three times. This is because instead of illuminating the sun, focusing gains light from the sun and two mirrors. Do ten mirrors and start to get the levels of heat that are useful for applications such as food cooking.

At least a few groups of fans produced a solar furnace that generates more than a thousand degrees of heat, capable of reducing most of the organic material to ashes.One place, a function of how exactly the mirrors can focus on focus. The solar furnace is one of those technologies that our ancestors would consider extremely useful, even if they had only means to produce highly reflective mirrors that didn't. Ancient mirrors were only polished silver or copper, while modern mirrors consist of a thin layer of aluminum stored on glass.

The system for stimulating the dishes is a sun furnace that uses parabolic mirrors to focus sunlight on rock salt that melts and can be used to heat water and steam for turbine control. These solar furnaces are more effective than photovoltaic solar cells. It is said that the Greek inventor of Archimedes used a solar furnace to ignite enemy ships during the war, but this is unlikely, because this technology did not reflect it exactly to the target of more than a few feet since then.
