First there is the energy required to power giant wind machines all day long, not to mention the electricity needed to pump coolant around tubes laid under the sand.

首先，这需要一整天启动风机制冷，更不要说还要大量电力在沙子下通过管道泵送制冷剂。

Steam generated by the heat of a cooling down reactor has enough force to run a turbine, which then runs a pump that provides coolant to the core.

由冷却的反应堆产生的蒸汽足够运行一台涡轮机，然后该涡轮机运行一台水泵为反应堆提供冷却剂。
