Background
According to the solar updraft tower (Solar updrift tower) uses sunlight to heat air around a wide central bottom of a high-rise chimney tower, such as under a greenhouse roof collector structure, whereby the resulting convection air causes hot air to rise in the tower through the chimney effect. This airflow drives wind turbines placed in the chimney updraft and around the bottom of the chimney to generate electricity. Based on model calculations, it is estimated that a 100MW power plant will require a 1,000 meter tower and a 20 square kilometer (7.7 square miles) greenhouse. However, the floor area is large, and the construction, maintenance and repair are difficult.
Concentrated Solar towers (Solar towers), also known as "central tower" power plants or "heliostat" power plants, are a type of Solar furnace that uses towers to receive concentrated sunlight. It uses a series of flat movable mirrors to focus the solar rays on a collection tower.
