First postulated in 1931 by Isidoro Cabanyes who discussed it in the magazine 'La energía eléctrica', this concept uses several key effects to work; the chimney effect, greenhouse warming and low velocity wind turbines.
The sun's radiation is used to heat a large body of air under an expansive collector zone (green houses in this case),
One of the major advantages of a Solar Tower over other renewable and traditional coal & nuclear energy producers is a Solar Tower does not use any water in the energy production process.
A US Department of Energy report 'Reducing water consumption of concentrated solar power electrictity generation', states coal, nuclear and heliostat CSP technology (power tower) utilize approximatley 500 gallons of water per MWh of power produced.
The Solar Tower project earmarked for Arizona will abate the approximate usage of 528 million gallons of potable water (drinking water) per annum.'
