It's incredibly lightweight, an exceptional conductor of heat and electricity and it's more than 100 times stronger than steel.

而且重量轻到令人难以置信, 而且是电优质导体，甚至比钢强100倍。

Sitting in a warm room reduces the power available from thermocouples.

处于温暖房间中会减少电偶产生可用能量。

Today, you learned about how engines turn thermal energy into work and how to calculate their efficiency.

，了解了电机如何转换能量 电偶工作原理以及如何计算它们有效性。

Russian investigators have detained three managers of the Norilsk power plant in Siberia on suspicion of breaching environmental protection regulations.

俄罗斯调查人员以涉嫌违反环境保护规定为由，拘留了西伯利亚诺里尔斯克电厂三名经理。

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

第二是选择电材料导性差（这样不同部分就能保持不同温度）但是导电性良好。

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

一种暴露在夜空就能发电简单电设备。

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电效应现象——而且还建立了一个模型来证明这个想法可行性。

The main heat sources were the electrical heat from spacecraft components and waste heat from their nuclear power sources – the Radioisotope Thermoelectric Generators.

主要源是来自航器部件电和来自核动力源——放射性同位素电发电机废。

Internally, the tower features a 1.2-megawatt cogen system that contributes to heating and cooling requirements; while floor-to-ceiling windows and column-free floor plates maximise natural light, reducing the extent of artificial lighting needed during the day.

在内部，塔楼具有 1.2 兆瓦电系统，有助于满足供暖和制需求，而落地窗和无柱地板最大限度地利用自然光，减少白所需人工照明。

So it turns out that there is an industry that is perfectly positioned to take us from the few geothermal power plants we have today to the hundreds of thousands that we need to meet demand.

结果发现，有一个产业，定位非常理想，可以把我们从仅有几座地电厂现况带到我们满足需求所需要数十万座电厂。

While the scientific accuracy of  this story has since been debunked, the concept is largely the same as that behind  South Africa's largest renewable energy project - the 250-metre-tall, 6.5sqkm  Redstone Solar Thermal Power Plant.

虽然此故事科学准确性已被揭穿，但其概念与南非最大可再生能源项目——250 米高、6. 5 平方公里红石太阳能电厂背后概念基本相同。
