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.

的，它不需要停泊的方，教授。但它需要电力发动，需要原料发电，需要钠产生电原料，需要煤制造钠，需要煤坑采掘煤炭。而正里，海水淹没了数森，些森质时期就埋人沙上了。

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.

样就形成了那些巨大的煤田，然而，些煤田并不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.

正样。些矿藏摆海水下面，像纽卡斯尔的媒坑一样。就方，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要煤。
