硅是地球表层最常见的元素,因为普通沙粒里都有硅。如果能够成功地以适合的成本把硅用作产生能量的物质,那么人类无疑将摆脱对能源的忧虑。纯硅带有与碳相同的能源密度的电池:一磅硅产生的能量与一磅碳产生的能量大致相 Silicon is the most common element on Earth’s surface because of the silicon in common sand. If silicon can be successfully used as a source of energy at a suitable cost, mankind will undoubtedly get out of energy concerns. Pure silicon Battery with the same energy density as carbon: a pound of silicon produces roughly the same amount of energy as a pound of carbon
