Mechanical devices are often described which claim to produce a net directional thrust from motion confined within the device. Thus far, no such device is known to have accomplished this claim without some reaction force transfer (usually of a viscous or frictional nature) to the external environment. Paul Brown presents examples of arguments sometimes used to justify the mechanical production of net thrust.
