We're going to be reviewing how we make power using power conversion systems.

我们将要回顾的是，我们如何创造能量，变换系统通过是要能量。

Then we'll discuss specifically two types of power conversion systems. One is the steam cycle which we call Rankine and the other is the Brayton cycle which is the gas cycle.

然后我们会特别的讨论2种能量，转化系统，一个是蒸气循环，我们称为兰金，另外一个是布雷登循环，那是气体循环。

I deliberately chosen not to include those because I wanted to show you that nuclear plants have containments and reactor or power conversion systems which typically steam turbines.

我特意选择不将那些总结，因为我想要给你们展示核电站，已经包含了，还有反应堆或者能量转化，系统，那是典型的蒸汽轮机。

If, on the one hand, you've got biofuels which represent only a half a percent conversion of sunlight, and let's say you've got photovoltaic cells and concentrated solar power systems, the efficiency of solar in terms of pure conversion is 50-100 times greater.
