Szilard's demon revisited

We show that piston fluctuations are of crucial importance in the analysis of a Szilard engine. Some engines which do not require information in order to perform a Szilard cycle actually do not work. We pinpoint the mechanism and stages which require work investment when a measuring instrument is reset.
