▌作品介绍：在学校中，我们的用电量非常大。可是却找不到省电的方法。我发现，在学校的上学、下课、放学的时候楼梯上总是挤满了同学。我想如果在楼梯之间安装上弹簧，这样当同学走下去的压力再通过一系列的动能转化机器就转化成电能提供给学校使用。还可以在楼梯扶手上安装按纽，这样按下去的压力也可以转化成动力。
此文自动翻译Introduction:In school, we use a lot of electricity. But there is no way to save electricity. I found that the stairs were always crowded with classmates at school, after class and after school. I would like to install a spring between the stairs, so that when the students go down the pressure through a series of kinetic energy conversion machines will be converted into electricity for school use. You can also install buttons on stair railings, so that the pressure can also be converted into power.
