Abstract: A hollow first housing with a rigid wall and a center of mass located on a portion of the rigid wall to which a weight is attached. When force is applied to tilt the apparatus then the center of mass is raised. When force is discharged, then a rocking motion of the hollow sphere device or housing will seek an equilibrium at the minimum gravitational potential energy. The rocking motion of the first housing activates a circular motion of a pendulum object. Motion of the pendulum object is passed to an electrical generator, which in turn produces electricity. The first housing may be a round circular hollow sphere, a circular cylinder, a cone, a frustrum, or may be configured in other shapes. A sail may be attached to an external surface of the first housing, at a location on the first housing furthest away from and opposite the weight.

Abstract: An apparatus is provided comprising a plurality of sections together forming a connected object, which may be a sphere. One half of the sphere can be rotated with respect to another half of the sphere in various planes or along various circular paths. In one embodiment the sphere has eight sections and can be rotated along any one of three different circular paths, A, B, and C. The plurality of sections may include first, second, third, fourth, fifth, sixth, seventh, and eighth sections. Each section may be joined to an adjacent section by a connector or in one embodiment by two connectors. Each connector may allow each section to rotate with respect to other sections. A plurality of connectors including twenty-four connectors for connecting eight sections may be provided. Each connector may be comprised of first and second curved rails and a first gear.
