Concentrated Solar Power

Concentrated Solar Power Plants
The newly opened Archimede solar plant in Sicily is able to generate electricity after the sun goes down, via innovative use of salt to store up heat for later use.
The solar plant generates electricity at night by using what is known as Concentrated Solar Power, absorbing the sun's heat and later using it to boil water and drive electricity-generating turbines. Concentrated Solar Power plants differ from photovoltaic plants, which generate power directly from sunlight.
It is more common for Concentrated Solar Power plants use a synthetic oil to store heat, but Archimede uses molten salt, which possesses a heat capacity able to drive its temperature up over 1000 degrees Fahrenheit. Even when the sun starts goes down, the salt is still hot enough to continue to boil water throughout the night.
