And that heat is then captured from the dancefloor and transferred to a series of 200-metre-deep boreholes which can be charged like a thermal battery.

然后，从舞池中产生的热量被收集并输送到一系列200米深的钻孔中，可以像热电池一样充电。

Uranus spends twenty Earth years like this, heating the deeper planet in one hemisphere while chilling the other, like charging a thermal battery.

天王星像这样度过了二十个地球年，在一个半球加热更深的行星， 同时冷却另一个半球，就像给热电池充电一样。
