Fireflies and some fish have the power to manufacture their own light, but the process seems to consume a large amount of energy.

萤火虫和某些鱼类可以用自己的能量自身产生光，但这个过程似乎会消耗大量的能量。

The best part is that the process can power itself—plutonium releases energy as it destroyed by fission, and that energy can power the burner.

最棒的是这一过程能够自我供能——钚被裂变破坏时释放能量，这一能量可以供给燃烧炉。

Instead it has to be manufactured by splitting water into hydrogen and oxygen, a process that consumes energy.

这种依靠人工的将水分离成氢和氧的过程也是需要消耗能量的。

The U.S.Department of Energy gave the Vehicle Research Institute a $500,000 grant to improve the biogas refining process and then demonstrate whether the fuel can be cost-competitive in cars.

And it's always going to come down to calculating the appropriate free energy, and how it changes in the process.

这总是涉及到计算,适当的自由能，以及这些自由能在过程中如何变化。

This is visualizing the process of the conversion of mechanical energy into chemical and electrical energy very nicely.

这一模拟恰到好处地演示了,机械能到化学能和电能的转换过程。

Global revenues from clean tech businesses--including air and water purification, advanced materials, distributed power generation, renewable energy, and process controls, such as sensors to monitor air and water--now surpass 85 billion pounds, according to the Cleantech Venture Network, a for-profit membership group that connects venture and institutional investors with entrepreneurs.

The spring is wound for half a minute, and then unwinds over six minutes, charging a battery in the process, and providing enough energy to run the radio for an hour. (This means the radio's spring-controller circuit is no longer necessary.) Thus, Freeplay has switched from making solely spring-powered devices to making battery-powered devices that are equipped with a clockwork mechanism for recharging and emergency use.
