我们每天在马路上行走,体重会对马路产生压力,我们可以把这些压力蓄存并利用起来。我们可以发明一种受压力发电的机器,安装在路面下。它的内部有一些零件像钟表的发条一样,人们踩它一下,它就会把这些压力转化为动力,再通过机器内部的发电机转化为电力。会发电的马路$广西藤县太 We walk on the road everyday, weighed down the road, and we can store and use that pressure. We can invent a pressure-driven machine, installed under the road. It has some parts inside the watch clockwork, people step on it, it will put these pressures into power, and then through the machine’s internal generator into electricity. The road that will generate electricity $ Guangxi Tengxian too
