Abstract

A multiple annulus energy storage system for generating and storing electrical power. The system characterized by individual rotating annuli which are permitted to rotate at speeds different from adjacent annuli.

Claims

1. A multiple annulus energy storage system for generating and storing electrical power, the system comprising:

a stationary housing;

a plurality of rotating annuli, the annuli disposed inside each other and received inside the housing;

electrical poles connected to each of the annuli;

field coils mounted in the housing and disposed adjacent the electrical poles; and

a power system controller connected to the field coils for receiving electrical energy therefrom and reversing the polarity of the system and exciting the coils for rotating the annuli during start up.

2. The system as described in claim 1 further including a bearing mounted in the housing and disposed adjacent the electrical poles for supporting the poles and the annuli thereon.

3. The system as described in claim 1 further including rotating shafts connected to each of the rotating annuli and the electrical poles.

4. A multiple annulus energy storage system for generating and storing electrical power, the system comprising:

a stationary housing;

a bearing surface mounted in the bottom of the stationary housing;

a plurality of rotating annuli, the annuli disposed inside each other and received inside the housing;

electrical poles connected to each of the annuli, the poles disposed above the bearing surface;

field coils mounted in the housing and disposed adjacent the electrical poles; and

a power system controller connected to the field coil for receiving electrical energy therefrom and reversing the polarity of the field coils for exciting the poles and driving the individual annuli during start-up of the system.
