Safety system for flywheel system for mobile energy storage

An improved integrated system for a flywheel-motor-generator assembly providing mobile energy storage and surge power generation, said system comprising:

• an outer housing
• a vacuum housing within said outer housing wherein said vacuum housing and said outer housing define a cavity;
• a pump for circulating a liquid in a predetermined portion of said cavity so as to transfer waste heat to said radiator;
• and
• a radiator;
• said improvement comprising:
• a reinforcing wrapping;
• wherein said liquid is an energy absorbing liquid,
• wherein said vacuum housing, said energy absorbing liquid, said outer housing and said reinforcing wrapping are arranged in the specifically recited order, which arrangement forms a multiple barrier and energy dissipation mechanism protecting a vehicle and associated passengers from accidental sudden release of energy from the flywheel assembly, and
• wherein said radiator is disposed outside of said reinforcing wrapping.

An isolation system for a flywheel-motor-generator assembly providing mobile energy storage having a support system including a liquid suspension system comprising an outer housing, a vacuum housing disposed within said outer housing, wherein said vacuum housing and said outer housing define a cavity capable of being filled with liquid, a radiator fluidly coupled to said cavity, and a pump operatively connected to said radiator and said cavity, wherein said pump, said radiator and said cavity define a cooling loop whereby said liquid is circulated between said radiator and said cavity so as to transfer waste heat to said radiator, said isolation system comprising:

• a reinforcing wrapping;
• and
• a mechanical gimbal including shearable gimbal pins for protecting the passengers and the vehicle from sudden transfer of angular momentum resulting from either bearing failure or contact between said vacuum housing and said flywheel assembly,
• wherein said liquid comprises an energy absorbing suspension liquid,
• wherein said vacuum housing, said cavity in which said energy absorbing liquid and said mechanical gimbal are disposed, said outer housing and said reinforcing wrapping are arranged in the specifically recited order to form a multiple barrier and energy dissipation means for protecting a vehicle and associated passengers from accidental sudden release of energy or said angular momentum from the flywheel assembly,
• wherein said gimbal pins in said gimbal shear so as to permit said vacuum housing to gradually spin down against said energy absorbing suspension liquid disposed between said vacuum housing and said outer housing, and
• wherein said radiator is disposed outside of said reinforcing wrapping.
