• Popis: In a recently published letter \cite{KSLU} the influence of particle statistics on extractable work in the Szilard engine \cite{Szilard} was discussed. We point out that the expressions given there suggest no work extraction is possible in the low temperature limit if more than two particles are used and thus are not optimal. We argue that the optimal extractable work is in general higher and in particular non-decreasing in the number of particles.
