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.

当量向上逃逸时，机将温差转化为能，这种能可为小型LED供。

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

如果这样的水器配上动机，那么太阳光就可以被连续使用。

It was by three RTGs, or radioisotope thermoelectric  generators.

它由三个 RTG（放射性同位素机）组成。

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

将来，有人想把材料铺在马路下面。

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的简单设备。

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

第二是选择的材料的导性差（这样不同部分就能保持不同的温度）但是导性良好。

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效应的现象——而且还建立了一个模型来证明这个想法的可行性。

Each probe is equipped with a long-lasting radioisotope thermoelectric  generator, which converts heat from the decaying plutonium 238 isotope into electric power.

每个探测器都配备了长效放射性同位素机，可将衰变钚 238 同位素产生的量转化为能。

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.

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