The Crescent Dunes Solar Energy Project near Tonopah, Nevada powers up to 75,000 homes during peak electricity periods. So how does it work? The project uses 17,500 heliostat mirrors to collect and focus the sun’s thermal energy to heat molten salt flowing through a 540-foot (160 m) tall solar power tower. The molten salt then circulates from the tower to a storage tank where it is used to produce steam and generate electricity. One last thing – look closely at the lower left corner of this Overview and you’ll see an airplane flying over the complex!

鄰近內華達州托諾帕的新月沙丘太陽能電廠在發電峰期能夠供應多達7萬5,000戶家庭的用電。這座電廠究竟怎麼運作呢?電廠使用1萬7,500面追日鏡搜集太陽的熱能,用以加熱流入太陽能塔(高達160公尺)的熔鹽。熔鹽再從塔內流入鹽坑,在其內製造蒸氣、並產生電力。對了,請仔細地看看本圖的左下角,你會看見一架飛機飛過電廠。
