Circular solar power tower

What is a Solar Tower? (with picture)

The solar tower is hollow, like a chimney, and extracts energy from the hot air rising rapidly to the top of the tower using turbines. The taller the tower, the more energy is extracted. The tower works 24 hours a day because the ground underneath the tower retains heat absorbed during the day and continues to release it at night.

A solar power tower, also known as ''central tower'' power plant or ''heliostat'' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun''s rays upon a collector tower (the target). Concentrating Solar Power (CSP) systems are seen as one viable solution for renewable, pollution-free energy.
