Impossible Sounding Solar Plant Generates Electricity At Night

Sceptics of modern technology, behold: a newly-opened solar plant in Sicily is able to continue generating electricity long after the sun goes down. The trick lies in the plant’s use of salt to store up heat for later use.[imgclear]

Most CSP plants use a synthetic oil to store turbine-driving heat, but Archimede uses molten salt, which possesses a heat capacity able to drive its temperature up over 538C. Even when the sun starts to dip, the salt is still, as you can imagine, rather hot – hot enough to continue to boil water at night. [Guardian UK via Inhabitat]
