  Recent advances in applying thermodynamic ideas to quantum systems have
raised the novel prospect of using non-thermal, non-classical sources of
energy, of purely quantum origin, like quantum statistics, to extract
mechanical work in macroscopic quantum systems like Bose-Einstein condensates.
On the other hand, thermodynamic ideas have also been applied to small systems
like single molecules and quantum dots. In this paper we study the quantum
thermodynamics of small systems of anyons, with specific emphasis on the
quantum Otto engine which uses, as its working medium, just one or two anyons.
Formulae are derived for the efficiency of the Otto engine as a function of the
statistics parameter.
