Right now, all over the world, people are using energy. As we drive our cars, work on our computers, or even cook food on a wood fire, we probably do not stop to think about where the energy comes from. But when the gas is gone and there is no more coal – what then?
Scientists are finding new answers all the time. Get ready for the children whose running feet make the energy to bring water to their village; for the power station that uses warm and cold water to make energy; for the car that saves energy by growing like a plant…
現在,世界各地的人正在使用能源,當我們開車、用電腦工作,甚至是用柴火煮飯時,我們可能不會停下來思考能源從哪裡來的,但是當天然氣消失而且沒有煤炭時,然後該怎麼辦呢?
科學家一直都在尋找新答案,為了得靠雙腳奔跑取水回村莊的孩子們做準備,使用溫水和冷水來製造能量的發電站,通過植物生長來節省能源。
