No, professor, but it needs electricity to run, batteries to generate its electricity, sodium to feed its batteries, coal to make its sodium, and coalfields from which to dig its coal.

是的，它不停泊的方，教授。但它电力发动，原料发电，产生电原料，煤制造，煤坑采掘煤炭。而正是在这里，海水淹没数森林，这些森林在质时期就埋人沙上。

Thus were formed those immense coalfields, which nevertheless, are not inexhaustible, and which three centuries at the present accelerated rate of consumption will exhaust unless the industrial world will devise a remedy.

这样就形成那些巨大的煤田，然而，这些煤田并不是取之不尽用之不竭的，而且按照目前加速的消费速度， 三个世纪之后， 除非工业世界能够想出补救办法， 否则这些煤田将会耗尽。

Precisely. These mines extend under the waves like the coalfields at Newcastle. Here, dressed in diving suits, pick and mattock in hand, my men go out and dig this carbon fuel for which I don't need a single mine on land.

正是这样。这些矿藏摆在海水下面，像纽卡斯尔的媒坑一样。就在这方，穿上潜水衣，手拿锄和铲，我的人员去采煤，我因此用不着向上的旷藏煤。
