Abstract: A wheel hub for capturing energy created by road bumps and converting that into energy to be used in moving a vehicle in it's current direction of motion. Energy return is accomplished by elastic spring means, although the physical principle of operation is not directly obvious. Any road shock imparted upon the wheel will result in a radial displacement of an outer wheel hub and thus a radial force toward the center of the wheel. The radial force will be released as an axial rotation imparted upon a wheel hub assembly, thus increasing the axial speed in the current direction of motion. The principle is similar to that causing the earth to rotate around the sun. The wheel hub assembly will not wobble erratically since there is a dampening component by virtue of a vehicles weight and moment of inertia of a rotating wheel. Additionally, total shock absorbtion, is increased.
