AB: The paper examines the role of unrestrained expansion in atmospheric entropy production. Lack of mechanical equilibrium is shown to be a far larger producer of internally generated entropy than other internally generated entropy production processes. Isentropic expanders are used to explain atmospheric entropy production. Unrestrained expansion can account for the discrepancy between the energy that would be produced if the heat were carried by Carnot engines and the energy actually produced. Having an expander in more important to mechanical energy production than reducing friction losses. The method of analysis is also applicable to: the solar chimney and to the atmospheric vortex engine.
