Feynman's ratchet optimization: maximum power and maximum efficiency regimes

The optimal performance of the Feynman ratchet-and-pawl engine is analyzed by taking the power and the efficiency of the engine as objective functions. The power-efficiency curves are also obtained. These curves show a loop shape similar to those characteristic of some real heat engines. Explicit an...

Zusammenfassung:	The optimal performance of the Feynman ratchet-and-pawl engine is analyzed by taking the power and the efficiency of the engine as objective functions. The power-efficiency curves are also obtained. These curves show a loop shape similar to those characteristic of some real heat engines. Explicit analytical expressions are reported in the so-called linear regime. (Author)
