A propulsion device which takes advantage of the fact that the mass of an object will decrease if the energy density of the object changes rapidly. The energy density is changed by causing rapid mechanical deformations of the object. By these means, the mass of a rotating object is decreased to one side of its axis of rotation, creating an unbalanced centrifugal force that acts on the rotating object as a propulsive force in the direction from the lower mass half toward the higher mass half. The propulsive force is used to propel an object or hold an object in position in opposition to an outside force or provide mechanical energy for a purpose such as the generation of electricity.

1. Field of the Invention
This invention relates generally to an apparatus for providing a propulsive force and more specifically to such an apparatus in which sections of a rotating object are caused to experience a mass decrease through part of the rotational period in order to create an imbalance of forces that results in propulsion.

FIG. 1
In FIG. 1, two cylinders sit side by side. An elastic cylinder 9 is made of a material that deforms more easily under mechanical stress than the material of a cylinder 10. The material of elastic cylinder 9 should be elastic in nature so that it regains its original shape after mechanical stress is released.
