| 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.

First Claim:
Show all 19 claims |
I claim:
1. A charged particle energy storage device comprising:
- a vacuum tube for housing a plurality of electrons circulating within the vacuum tube;
- a magnetic field generator for providing a magnetic field having closed magnetic field lines within the vacuum tube; and
- an electron source for delivering a plurality of electrons into a predetermined path within the vacuum tube, the electrons having a substantially uniform velocity such that the predetermined path comprises a spiral about an axis that is parallel to a closed magnetic field line of the magnetic field;
- a gas source for delivering a plurality of gaseous particles into the vacuum tube such that the gaseous particles interact with the electrons to form energized particles; and
- a valve to control an opening in the vacuum tube such that the energized particles can be removed from the vacuum tube through the opening.
