The intense, glowing brightness at the top of the tower is caused by a highly advanced molten salt heat receiver.How It WorksThe Mirrors: The plant features over 40,000 highly precise tracking mirrors called heliostats. These mirrors follow the sun's trajectory throughout the day and reflect concentrated sunlight directly toward the top of the tower.The Glow: The "blinding" light isn't coming from lightbulbs; it is the sheer intensity of thousands of sunbeams focusing onto a single point. This intense energy heats up a mixture of liquid molten salt running inside the receiver to temperatures over 550°C.The Thermal Battery: The heated salt acts like a massive thermal battery. When electricity is needed, the hot salt converts water into high-pressure steam, which turns a traditional turbine to generate electricity.Why It Can Run At NightBecause the molten salt stores heat so effectively, the Redstone CSP plant can continue to boil water and generate full-scale electricity for up to 12 hours after the sun goes down. This allows the plant to provide clean, non-intermittent power to up to 200,000 South African homes, especially during peak night hours.

Formula 1 Dad :
That’s called a Concentrated Solar Power (CSP) system, it uses mirrors to direct the solar rays to the top of the tower and converts it to electricity.

One of the reasons why we are going to experience hotter summer temperatures and drought they act like they are bringing clean energy instead they are accelerating the global warming

not a solar plant, thats for a steam turbine.

Arefa lekoko :
Hundreds or thousands of mirrors (called heliostats) are arranged around a tall tower.
2. The mirrors track the sun and reflect sunlight toward a receiver at the top of the tower.
3. The concentrated sunlight creates extremely high temperatures in the receiver.
4. That heat is transferred to a working fluid, commonly molten salt or another heat-transfer fluid.
