摘要
Water occupies 70% of the earth’s surface.It not only supports our life but also contains abundant energy.Water exists in different forms,including in oceans,rivers,and lakes,where they can evaporate upon solar radiation.The temperature difference in the atmosphere acts like a pump to pull up the evaporated water,through which the water in the cloud obtains the gravitational potential energy.Such energy then transfers into kinetic energy in the raindrops falling down[1].How to utilize the raindrops’energy has long been a fascinating question.Although traditional hydraulic power generation is more applicable to continuous flow of water,it becomes inefficient with relatively less rainfall supply[2].Therefore,a new strategy to harvest the kinetic energy stored in the form of raindrops is highly desired.
