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。

Temperature differences between the body and the ambient air mean that thermoelectric couples can generate useful quantities of juice.

人体与外部环境的温差意味着热电偶能够产生一定数量能量。

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，种电能可为小型LED灯供电。

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

如果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。

In the future, some people want to put thermoelectric materials under the roads.

将来，有人想把热电材料铺在马路下面。

Raman's team has developed a potential solution: a simple thermoelectric device that generates power when it's exposed to the cold night sky.

一种暴露在寒冷的夜空就能发电的简单热电设备。

The second is to choose a thermoelectric material which conducts heat badly (so that different parts remain at different temperatures) but electricity well.

第二是选择的热电材料的导热性差（样不同部分就能保持不同的温度）但是导电性良好。

Then, the exhaust heat from the bottom plate of the thermoelectric device would be used in the traditional way to warm water up.

其次，从热电设备中位于底部的薄片中出来的排气可以用于传统方式来加热水。

They suggest that a phenomenon called the thermoelectric effect might be used instead—and they have built a prototype to show that the idea is practical.

他们提出可以利用一种名为热电效应的现象——而且还建立了一个模型来证明个想法的可行性。

The reason thermoelectric materials have not, in the past, been applied successfully to the question of solar power is that to get a worthwhile current you have to have a significant temperature difference.

为什么在过去热电材料没能成功地应用到太阳能上呢，是因为如果要获得有价值的电流必须有巨大的温度差。
