The book begins with familiar designs found all around and inside us (such as the \'trees\' of river basins, human lungs, blood and city traffic).
Finally, Professor Bejan explains how people, like everything else that moves on earth, are driven by power derived from our "engines" that consume fuel and food, and that our movement dissipates the pow.
It then shows how all flow systems are driven by power from natural engines everywhere, and how they are endlessly shaped because of freedom.
