Bad news, it involves me digging up the radioisotope thermoelectric generator.

坏消息就是我得把放射性同位素热电机挖出来。

If such heaters were covered with thermoelectric generators the sun's rays could be put to sequential use.

如果这样的热水器配上热电发动机，那么太阳光就可以被连续使用。

As heat escapes upwards, a thermoelectric generator converts the temperature difference into electricity that powers a small LED light.

当热量向上逃逸时，热电发电机将温差转化为电能，这种电能可为小型LED灯供电。
