The [[w:solar updraft tower|solar updraft tower]] is a renewable-energy power plant for generating electricity from solar power. Sunshine falling on a greenhouse-like collector structure around the base of a tall chimney heats the air within it. The resulting convection causes air to rise up the tower by the chimney effect. This airflow drives wind turbines to produce electricity.

The solar updraft tower is a renewable-energy power plant for generating electricity from solar power. Sunshine falling on a greenhouse-like collector structure around the base of a tall chimney heats the air within it. The resulting convection causes air to rise up the tower by the chimney effect. This airflow drives wind turbines to produce electricity.

[edit] Land use

The collector diameter is around 750 m = 400,000 m^2 = 100 acre (60 soccer pitches)<ref>http://educypedia.karadimov.info/library/Solar%20Updraft%20Towers.pdf</ref>

Considering land prices as follows, the solar updraft tower will cost 100,000 - 1,000,000 USD for land only.
