An energy tower (also known as a downdraft energy tower, because the air flows down the tower) is a tall (1,000 meters) and wide (400 meters) hollow cylinder with a water spray system at the top. Pumps lift the water to the top of the tower and then spray the water inside the tower. Evaporation of water cools the hot, dry air hovering at the ...
The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the ...
An energy tower (also known as a downdraft energy tower because the air flows down the tower) is a tall (1,000 meters) wide (400 meters) hollow cylinder with a water spray system at the top. Alternatively, temperature decreases uniformly with positive changes in altitude at a rate of ~ 16° C per mile.
The Energy Tower is a machine that produces wind. Hot and dry air is cooled within a very large vertical duct which looks like a high and very large diameter chimney. A fine spray of water is introduced across the top inlet to the duct. The water evaporates and cools the air.

Windcatcher. An ab anbar (water reservoir) with windcatchers (openings near the top of the towers) in the central desert city of Yazd, Iran. Aghazadeh Mansion in Abarkooh, Iran, has an elaborate 18-m windtower with two levels of openings, plus some smaller windtowers. A windcatcher, wind tower, or wind scoop (Persian: بادگیر) is a ...
Solar chimney. A solar chimney – often referred to as a thermal chimney – is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.
Energy tower (downdraft) – EURO-SOLAR Programme – European Photovoltaic Industry Association (EPIA) – is the world's largest solar photovoltaic (PV) industry association, representing around 95 percent of the European photovoltaic industry and 80 percent of the worldwide PV industry.
