A solar mirror contains a substrate with a reflective layer for reflecting the solar energy, and in most cases an interference layer. This may be a planar mirror or parabolic arrays of solar mirrors used to achieve a substantially concentrated reflection factor for solar energy systems.
Liquid-mirror telescopes have rotating mirrors that consist of a liquid metal such as mercury or a low-melting alloy of gallium. These mirrors do not solidify and they are used while liquid and rotating. The rotation shapes them into paraboloids that are accurate enough to be used as primary reflectors in telescopes.
Parabolic reflectors are popular for use in creating optical illusions. These consist of two opposing parabolic mirrors, with an opening in the center of the top mirror. When an object is placed on the bottom mirror, the mirrors create a real image, which is a virtually identical copy of the original that appears in the opening. The quality of ...
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 ...
A solar power tower, also known as 'central tower' power plant or 'heliostat' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target).
A solar parabola is a parabolic mirror that concentrates the sunlight to reach high temperatures. In Auroville 's collective kitchen, a large solar parabola on the roof provides heat for cooking. The solar parabola can also be used for industrial building.
The mirror rotates on an altazimuth mount. The Solar Two solar-thermal power project near Daggett, California. Every mirror in the field of heliostats reflects sunlight continuously onto the receiver on the tower. The 11MW PS10 near Seville in Spain. When this picture was taken, dust in the air made the converging light visible.
