Dissipative heat engine is thermodynamically inconsistent [PDF]

, 2009
A heat engine operating on the basis of the Carnot cycle is considered, where the mechanical work performed is dissipated within the engine at the temperature of the warmer isotherm and the resulting heat is added to the engine together with an external heat input.
