能源问题就好像一枚硬币的两面,一面是我们从哪里取得能源,就是能源的采集问题.笔者在上几期中已经简要地介绍了几种主要的新能源,尤其是可再生新能源,包括风能、太阳能等.另一面是如何储存采集到的能源.我童年的时候,看过一部叫做《变形金刚》的动画片,对片中“擎天柱”和“霸天虎”争夺能量块的情节记忆犹新,因为能量块可以供他们完成星际旅行.动画片的情节很精彩,可是在现实中,能量的储存就不那么简单了.能源储存的问题不仅仅是国际科 The issue of energy is like two sides of a coin, on the one hand where we derive energy, which is the issue of energy harvesting. The author has briefly outlined several major new sources of energy, particularly renewable energy sources, including wind energy , Solar energy, etc. The other side is how to store collected energy. When I was a child, I watched an animated film called “Transformers” The battle for energy blocks is vividly remembered because the energy blocks allow them to complete the interstellar journey. The animated plot is fantastic, but in reality, energy storage is not that easy. The issue of energy storage is not limited to the International Section
