  • Publication number: 20030075928
    Abstract: The apparatus converts mechanical, or kinetic, energy into electricity, the energy being produced through the relative movement of two pistons toward and away from each other. At least one object (which can be either magnetized, a rod, or both) reciprocates between the first and second pistons as these pistons move toward each other, on odd numbered approaches the object moves from the first piston to the second and on even numbered approaches it moves from the second piston back to the first piston. A conductive coil in one of the pistons converts the kinetic energy of the magnetized reciprocating object into electrical energy. To drive the object toward the second piston with greater speed (hence greater energy content) a current of appropriate polarity applied to the coil in the first piston ejects the object with said increased speed.

  • Patent number: 4014168
    Abstract: Typical embodiments of the invention can be used for photon generation, plasma containment or for atmospheric and/or space vehicle propulsion. Illustratively, a large dome of insulating material supports an array of smaller insulating domes. Conducting electrodes that are embedded in the external surfaces of these smaller domes are coupled to a high frequency alternating current. The electrical potential on these electrodes produces ionization in the medium external to the dome array. The ions, charged with a potential that is the same as electrode voltage, are repelled from the dome array in a preferred direction. This action establishes a resultant force that can be used to drive the array through the medium in a direction opposite to that of the ions. The ionization phenomena produced in accordance with the described technique also generates abundant photons.
