Abstract: A centrifugal force propulsion device includes an eccentric rotor rotatably mounted to a base via a shaft. The rotor has an aperture therein which is substantially larger than the shaft, such that the rotor is able to rotate at speed away from the shaft, as well as move longitudinally perpendicular to the axis of rotation. A drive motor drives the rotor through a stretchable flexible belt. As centrifugal force rotates the rotor toward a longitudinal standing position alone away from the shaft and drive motor, and as the drive belt is stretched, the increased tension therein pulls the drive motor and base ahead following the rotor, thus pulling the device in a desired direction.
