地球深处的热能地球上有许多活火山，它们喷出的炽热的岩浆中蕴藏着很大的能量。美国夏威夷群岛的活火山，经常喷出岩浆，滚滚注入太平洋，激起的蒸汽热浪冲天而起。这些蒸汽不正好是火力发电厂用来驱动汽轮机发电所需的蒸汽吗？是否可以利用火山岩浆的巨大热能来发电呢？... Heat in the Deep Earth There are many active volcanoes on Earth, and the glowing magma they emit contains a great deal of energy. Active volcanoes in the Hawaiian Islands of the United States often spray magma and plunge into the Pacific Ocean, causing the heated heat waves to heat up. Is the steam not exactly the kind of steam that a thermal power plant uses to power the turbines? Is it possible to use the huge heat of volcanic magma to generate electricity? ...
