Sadi Carnot and the Thermodynamics of James Watt

A comparison of Carnot’s thermodynamic statements, published in his Reflections, with the Watt’s ideas shows that Carnot used thermodynamics, but he did not understand it properly. For instance, realize idea production work steam engine requires a consumption heat. Also, instead pressure difference boiler-to-condenser, temperature to be direct quantity for transport caloric engine. Many statements are shown express other wording. Watt realized reversible heat transfer experiment several decades prior Reflections. In addition, analogy and water fall, 1824, has been invalidated, long before its birth, by formulation first law 1774. Despite these facts, James is banished from history thermodynamics.
