And, we'll talk about fuel cells later in the semester when we do the unit on redox reactions and electrochemistry.
这学期我们随后会讨论燃料电池,当我们讲到,关于氧化还原反应和电化学单元时。

It's biological engines, right. Things that either produce or consume biological fuel to do different sorts of processes. Also, of course of key importance to understand what the, in that case, biological thermodynamics are.
但不只是我们制造的引擎,生物引擎也是如此,它们产生或消费生物燃料,来完成不同的过程，当然，这也是理解生物热力学的关键所在。
-
What you've built is an engine. You cool, you heat, you heat, you cool, you get back to the same place, but you've just done work to the environment.
这就是热机，我们用燃料或者热源加热，然后把它，与大气接触让它冷却。
