Solar Tower

$70.1

A solar tower is a structure used to support equipment for studying the sun, and is typically part of solar telescope designs. Solar towers are used to raise the observation equipment above the atmospheric disturbances caused by solar heating of the ground and the radiation of the heat into the atmosphere. Traditional observatories do not have to be placed high above ground level as they do most of their observation at night when ground radiation is at a minimum.The horizontal Snow solar observatory was built on Mount Wilson in 1904. It was soon found that heat radiation was disrupting observations. Almost as soon as the Snow Observatory opened, plans were started for a 60 foot tall tower that opened in 1908 followed by a 150 foot tower in 1912. The 60 foot tower is currently used to study helioseismology while the 150 foot tower is active in UCLAs Solar Cycle Program. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Ps20 Solar Power Tower

$78.07

High Quality Content by WIKIPEDIA articles The Planta Solar 20 or PS20 solar power tower is a solar thermal energy plant in Sanlucar la Mayor near the southern Spanish city of Seville. It is the worlds most powerful solar power tower. The 20 megawatt solar power tower produces electricity with large movable mirrors called heliostats. Solar thermal energy (STE) is a technology for harnessing solar energy for thermal energy (heat). Solar thermal collectors are defined by the USA Energy Information Administration as low, medium, or hightemperature collectors. Low temperature collectors are flat plates generally used to heat swimming pools. Mediumtemperature collectors are also usually flat plates but are used for creating hot water for residential and commercial use. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Solar Tres Power Tower

$68.51

High Quality Content by WIKIPEDIA articles Solar Tres is a planned 15 MW power plant based on solar thermal energy. It is located west of the city of cija, in Andalusia, Spain. Solar Tres is based on the solar power tower concepts pioneered in the U.S.s Solar One and Solar Two demonstration projects. Solar Tres uses a molten salt as its working fluid, allowing it to be stored in the molten state for power generation at any time. The project, which has received a subsidy of five million Euro from the European Commission, makes use of the Solar Two technology tested in Barstow, California, but will be approximately three times the size. Solar Tres will make use of several advances in technology since Solar Two was designed and built. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Solar Power Tower

$68.51

High Quality Content by WIKIPEDIA articles The solar power tower (also known as Central Tower power plants or Heliostat power plants or power towers) is a type of solar furnace using a tower to receive the focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the suns rays upon a collector tower. Early designs used these focused rays to heat water, and used the resulting steam to power a turbine. However, designs using liquid sodium in place of water have been demonstrated; this is a metal with high heat capacity, which can be used to store the energy before using it to boil water to drive turbines. These designs allow power to be generated when the sun is not shining. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Practical Solar, Inc.

$58.94

High Quality Content by WIKIPEDIA articles Practical Solar, Inc. is an American manufacturer of heliostats used for concentrating solar power, as well as for residential and commercial natural lighting (daylighting) applications. The company, located in Boston, Massachusetts, introduced its heliostat system for sale in February 2009. Practical Solars heliostats are small in the spectrum of heliostats commercially available for harnessing solar thermal energy. They each have 8 square feet (0.74 meters) of reflector area. To put this in perspective, the heliostats in a solar power tower project in Seville, Spain each have reflectors nearly 1,300 square feet in size (120 square meters). Practical Solars heliostat system is the first computercontrolled heliostat system that can be installed by hand, using only hand tools. Practical Solars founder Bruce Rohr suggested in Northeast Sun magazine that small heliostats are more reliable and more costeffective per square meter of reflective area than the larger heliostats typically used in solar power tower projects.
