	Encyclopedia: Solar Tower
		A solar tower is an environment-friendly way of generating power by exploiting the temperature differential between air at ground level and air at a significant elevation.
		At the base of a solar tower is a solar collector - a huge (~25,000 acres or 100 square kilometers) transparent circular skirt made of plastic that creates a greenhouse effect and heats the air trapped in the skirt.
		Solar Tower technology is created when the sunÂ’s radiation is used to heat a large body of air, which is then forced by the laws of physics (hot air rises) to move as a hot wind through large turbines to generate electricity.

	Solar tower - Wikipedia, the free encyclopedia
		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.
		Almost as soon as the Snow Observatory opened, plans were started for a 60 foot tall tower that opened in 1908 follower 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 UCLA's Solar Cycle Program.

	New Green Energy - Solar Tower Of Power
		Announced several years ago, the 3,280-foot Solar Tower is one of the most ambitious alternative energy projects on the planet: a renewable energy plant that pumps out the same power as a small reactor but is totally safe.
		"Solar chimneys (towers) have become a hot area of research recently," said S.A. Sherif, a professor of mechanical and aerospace engineering at the University of Florida, who wrote several papers on the technology in the early 1990s and is the technical editor of the Solar Energy journal.
		"Solar towers are a good fit for power companies because they operate 24/7 and deliver maximum energy output during the hottest part of the day just when everyone's air conditioners are on high," he said.

		In 1908, Hale discovered magnetic fields in sunspots (using the 60-foot solar tower built in 1907) by applying the principle of Zeeman splitting, where a spectral line will usually be split up into several components in the presence of a magnetic field.
		Solar rotation studies were begun by Walter S. Adams in 1911 which produced very accurate spectroscopic rotation results and hinted at a velocity field that is now called supergranulation.
		Digital data obtained at the solar tower (recorded on punched paper tape) were taken in 1962 and 1963.

	SolarMission Technologies, Inc. :: The Solar Tower Project is designed to provide large scale renewable energy with ...
		Solar Towers operate on the simple principle hot air rises; the movement of rising hot air is utilized to drive turbines to generate electricity.
		The turbines are located at the base of a very tall tower in the center of the collector, and the movement of the heated air through these turbines is increased by the updraft effect created by the tower.
		The solar tower can produce electrical generation in large-scale quantities and be a competitive alternative to coal and gas based electricity generation.

		Of these technologies the solar dish/Stirling has the highest energy efficiency (the current record is a conversion efficiency of 30% of solar energy).
		Because it is "mostly concrete with a few moving parts" and does not have a lot of mechanical complexity, the solar chimney is also considered to be economically attractive because it fits into the existing investment asset classes and risk models as conventional power stations and other heavy infrastructure that investment banks are familiar with.
		Australia's only existing solar power station, White Cliffs Solar Power Station, was originally built using solar dish/steam turbine technology, but has now been upgraded to photovoltaic to obtain almost twice the electric output from the same dishes.

		It is an ambitious plan by anyone’s standards: to build the world’s tallest structure to siphon solar energy from the flat, arid landscape of Neds Corner, near the Murray River in north-western Victoria.
		A 1km solar tower would be far more conspicuous but the corresponding “footprint” of 40-odd towers would be less than 800 sq km; about 28km on a side.
		Solar towers would help Victoria, which is heavily dependent on brown coal-sourced electricity, out of its bind in the Latrobe Valley.
