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

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