  • 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.

  • Energy storage device having a plurality of single charged particles and a charge neutralizer
    Patent number: 6140752
    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.
