Water Battery
The World’s Biggest Water Battery
We can use the power of water to make clean energy, without any smelly smoke
or dirty pollution.
我們可以用水力製造乾淨的能源，還不會製造汙染跟濃煙！
That’s why, high in the mountains of Switzerland, they’ve just built the
world’s biggest water battery!
現在瑞士在一座高山上，蓋了世界最大的水電池！
It’s made of two huge lakes, one high above, and one down below. To make
electricity, water moves super-fast from the high lake down to the low lake,
through big long tunnels!
這個電池由兩座湖構成。水會從比較高的湖，通過隧道流到比較低的湖裡面，這樣就可以發電！
Inside the tunnels are huge turbines. They look like the blades of a fan, but
much, much bigger!
隧道裡面有很大很大的渦輪，長得很像電風扇的葉片。
The power of the rushing water makes the turbines spin really fast. As the
turbines spin, they make electricity!
水沖過渦輪，渦輪會開始高速轉動，就可以產生電力！
This water battery is so big it took 14 years to build, and it can make
enough electricity to power 900,000 homes! That’s more than they need in
Switzerland, so they want to share it with the rest of Europe.
蓋這個水電池一共花了14年，生產的電力可以供應九十萬個家庭使用。因為自己用不完，瑞士打算跟其他國家分享！
Lots of clean energy for folks all over Europe, for years, all thanks to the
world’s biggest water battery!
