We show analytically and numerically that the presence of nonzero odd moments leads to a macroscopic current. For a noise with a vanishing third moment we find that the current changes sign as the potential or the noise strength is increased. Possible physical situations are discussed including motor-protein motion and driven systems like fluidized beds.4 pages, latex, 2 figuresCondensed Mattertext
