Why We Can’t Invent a Perfect Engine: Crash Course Engineering #10

We’ve introduced the 0th and 1st laws of thermodynamics, so now it’s time to move on to the second law and how we came to understand it. We’ll explain the differences between the first and second laws, and we’ll talk about the Carnot cycle and why we can never design a perfectly efficient engine.

Crash Course Engineering is produced in association with PBS Digital Studios.
