Abstract:
1. An electro-dynamo device, comprising: a stator comprising a plurality of stator arms and a stator core characterized by ferromagnetic properties at cryogenic operating temperatures and paramagnetic properties at non-cryogenic temperatures; a plurality of stator coils attached to the plurality of stator arms; a rotor connected to a rotatable shaft, the rotor comprising a plurality of rotor arms and a rotor core characterized by ferromagnetic properties at cryogenic operating temperatures and paramagnetic properties at non-cryogenic temperatures; and a plurality of high-temperature superconductors attached to the plurality of rotor arms, wherein the rotor is configured to rotate with respect to the stator such that the plurality of high-temperature superconductors interact with the plurality of stator coils to produce a current in the plurality of stator coils when operating in a generator mode and to provide torque on the rotatable shaft when operating in a motor mode.
