title: A Two-Stroke, Two-Cylinder Piston Rotaxane Motor.
abstract: We introduce a model for a rotaxane motor. This uses two major themes of rotaxane physics, that is, the ability to change the potential of different regions of the axle (switching) and the entropy associated with free rings. The motor is based on free rings being trapped and released by potential stripes or stations. We calculate the power produced by such a motor, which is in the femtoWatt range. The power is proportional to the square of the number of rings.
