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

主要的热源是来自航天器部件的电热和来自核动力源——放射性同位素热电发电机的废热。

A turbine spins a magnet inside a coil to produce electricity, and since electromagnets need a power source, this turbine is powered by wind.

涡轮机旋转线圈内的磁铁来发电，由于电磁体需要电源，因此该涡轮机由风提供动力。

Renewable energy could be a power source, and that could really drive community development, and so I decided that I'll go ahead, and create this company called Solar Bear.

可再生能源可以成为一种能源， 可以真正推动社区发展，所以我决定继续前进， 创建这家名为 Solar Bear 的公司。

Permanent magnets do not need a power source, but this means that we can also turn electromagnets on and off, which is pretty cool when you think about it.

永磁体不需要电源，但这意味着我们也可以打开和关闭电磁体，想想看，这真是太酷了。

But I think that does show their power in the market, which is, of course, a source of tension in the music industry, and so is this issue of merch cuts.

但我认为这确实显示了他们在市场上的力量，这当然是音乐行业紧张的根源，商品削减问题也是如此。

LIKE any other electrical device, a pacemaker needs a power source. Since the first permanent pacemaker was installed in 1958, manufacturers of implantable medical devices (IMDs) have tinkered with many different ways of supplying electricity to their products.

和其他所有的电子设备一样，一个起搏器同样需要能源。自从1958年第一个永久起搏器被植入后，可植入医疗设备的制造商就在不断尝试为其产品提供电能的各种方法。
