  • Systems and methods for generating electron spiral toroids
    Patent number: 10201070
    Abstract: A spheromak is a plasma of ions and electrons formed into a toroidal shape. A spheromak plasma can include electrons and ions of nearly equal amounts such that it is essentially charge neutral. It contains large internal electrical currents and their associated internal magnetic fields arranged so that the forces within the spheromak are nearly balanced. The spheromak described herein is observed to form around an electric arc in partial atmosphere, and is observed to be self-stable with no external magnetic containment.

  • Energy storage device
    Patent number: 6617775
    Abstract: Electrons are arranged so they circulate along a spiral path in a vacuum. The path has a hollow symmetrical shape which is defined by a surface of a toroid. The shape is controllable by a magnetic field and the electrons can be contained within the shape. A containing force can be created by external electromagnetic fields, ions within the vacuum, or by interactions between the orbiting electrons themselves. The contained electrons store energy for later retrieval.

  • Energy storage and recovery system
    Patent number: 6603247
    Abstract: An energy storage device in which a vacuum tube and a magnetic field are used to store electrons circulating within the tube along spiral paths. The vacuum tube can have a generally toroidal shape and contains an electron gun or filament to inject electrons into the tube. Systems for retrieving electrons and precisely controlling their movement within the tube use a microprocessor control circuit that may be programmed to perform energy storage and retrieval functions.

  • Propulsion system
    Publication number: 20030019204
    Abstract: The propulsion system of the present invention includes charged particles held in a containment structure at high temperatures. Propellant is injected into the containment system where it collides elastically with the charged particles. The propellant is heated until it achieves a high velocity. It can then be ejected to produce thrust. The propulsion system can include thrusters to propel, for example, space launch vehicles and jet aircraft.
