  Originally, the Carnot cycle is a theoretical thermodynamic cycle that
provides an upper limit on the efficiency that any classical thermodynamic
engine can achieve during the conversion of heat into work, or conversely, the
efficiency of a refrigeration system in creating a temperature difference by
the application of work to the system. The aim of this paper is to introduce
and study the economic Carnot cycles into a Roegenian economy, using our
Thermodynamic-Economic Dictionary. Of course, the most difficult questions are:
what is the economic significance of such a cycle? Roegenian economics is
acceptable or not, in terms of practical applications? Our answer is yes for
both questions.
