Contra-rotating homopolar motor-generator for energy storage and return
First Claim
1. An apparatus for receiving electrical energy, storing the energy as rotational mechanical energy, and delivering the stored energy to a load as electrical energy, the apparatus comprising:
- a. a plurality of electrically conducting nested coaxial concentric cylindrical shells;
b. a plurality of electrically insulating cylindrical shells coaxial and concentric with each other and with the conducting shells and disposed to insulate the conducting shells from each other;
c. an electromagnet disposed to produce a magnetic flux that is directed radially through the conducting shells;
d. a plurality of air bearings disposed to support the conducting shells in rotation about an axis;
e. an air supply connected to the air bearings to supply air flow therethrough;
f. a plurality of spokes connected to the electromagnet and to the insulating cylindrical shells to maintain the insulating shells in fixed irrotational engagement;
g. a plurality of brushes connected to the conducting shells at edges thereof to create a series electric circuit therethrough that carries electric current in opposite axial directions in adjacent conducting shells;
h. a first terminal connected to one of the brushes that is connected to an innermost conducting shell; and
i. a second terminal connected to one of the brushes that is connected to an outermost conducting shell to form a series circuit through the conducting shells and brushes to the first terminal, whereby electrical energy that is supplied to the first and second terminals is stored as rotational mechanical energy in the conducting cylinders for delivery as electrical energy to a load.

Abstract
An apparatus for receiving electrical energy in amounts of the order of hundreds of megajoules, converting the electrical energy to mechanical energy for storage, and delivering the stored energy as electrical energy in times of the order of a second comprises a sequence of stacked electrically conducting cylindrical shells having a common axis. The conducting shells are free to rotate and are separated by stationary insulating cylindrical shells. Adjacent conducting shells are connected electrically by brushes at the edges and a radial magnetic field is caused to pass through the conductors. The apparatus permits the reversal in a plasma heating coil of electric currents of amplitudes up to 100,000 amperes in a time of the order of a second.
