Description

We accept the idea of power of a Force of Nature as it arises from Sadi Carnot’s Waterfall Analogy. We show in what sense power is experientially and conceptually primary, and how it can be used for motivating the energy principle (rather than taking power as derived from the concept of energy). We use a macroscopic steady-state model of irreversible thermal engines for demonstrating that Carnot’s notion of power cannot be derived from the concept of energy.
