Abstract

A molecular motor is introduced which is composed of charges only and which does not contain any potential or interaction besides the Coulomb one. The motor is shown to transform efficiently a driven random rotation into a directed translational motion. The direction of translational motion can be chosen dynamically, so that a ''forward gear,'' a ''reverse gear,'' and even a ''neutral gear'' exist. The high efficiency stems from the fact that this motor only steps in the direction determined by the chosen gear.
