Submission + - First solar power plant that works at night (dailymail.co.uk)
surveyork writes: The world's first commercial Concentrated Solar Power (CSP) plant that generates power at night has recently been commissioned.
"The Gemasolar Power Plant near Seville in southern Spain consists of an incredible 2,650 panels spread across 185 hectares of rural land.
The mirrors — known as heliostats — focus 95 per cent of the sun's radiation onto a giant receiver at the centre of the plant.
Heat of up to 900C is used to warm molten salt tanks, which create steam to power the £260million station's turbines.
But, unlike all other solar power stations, the heat stored in these tanks can be released for up to 15 hours overnight, or during periods without sunlight."
