1·The water from a water-fall needs to be controlled and contained before it can become useful energy.

从水坠水的需要加以控制，并载有前它可以成为有用的能源。

2·Energy is a resource that directs or provides the useful energy through the transformation the human needs.

能源是可以直接或通过转换提供人类所需的有用能的资源。

3·Faeces are food that has been processed by the human digestive system to extract as much useful energy as possible.

人类粪便是已经被人类消化体统为了最大化汲取能量而处理过了的食物。

4·Don't forget, no machinery is perfect and will not, therefore, convert all energy presented to it into useful energy for your use.

别忘了，没有机器是完美的，不会，因此，转换所有能源成有用的能量提交给它供您使用。

5·One way to release useful energy from plant matter is to ferment it into biofuels, as Synthetic Genomics, LS9 and Amyris are trying to do.

释放植物有用能源的一个方式是将其发酵转化为生物燃料，就如Synthetic Genomics, LS 9 and Amyris他们正在尝试做的。

6·Getting useful energy from formate is now the simplest way known for any life form to get its fuel, though it relies on the absence of oxygen.

从甲酸盐中获取所需的能量是目前最简单的维持生命方式，虽然它依赖于无氧的环境。

7·Dr Kanatzidis argues that wherever heat is generated as part of power generation, thermoelectric devices could help extract more useful energy.

Kanatzidis博士认为，热电装置可以收集发电过程中产生的热能，并将其转化为其他可用能量。

8·To generate useful energy, plants have evolved very sophisticated nano-machinery which operates with light as its energy source and gives a perfect quantum yield of 100%.

为了产生有效能，植物进化出了异常精密的“纳米机器”，它以光为能量来源，光能转化率达到了完美的100％。

9·In 1867 James Clerk Maxwell, a British researcher, wondered if you could extract useful energy from thin air, in apparent contradiction to the second law of thermodynamics.

1867年，大不列颠研究员James Clerk Maxwell想知道能否从稀薄的空气里提炼出有用的能量。这明显与热力学第二定律相矛盾。

10·The building of a real-life version of Maxwell's demon – which can turn information into useful energy – might mean that future nanomachines can be powered purely by information.

建造“麦斯威尔妖”的现实生活版本——它可以把信息转变为有用的能量——意味着未来的毫微级计算机可能纯粹地依靠信息来作为动力。
