Abstract
A mechanical energy storage system includes a containment vessel, a drive shaft operatively connected to a generator/motor and supported for rotation in the containment vessel. A support structure is attached to the drive shaft and configured for radial extension from a rest position proximate the drive shaft. A resilient member having a mass and extending circumferentially around the drive shaft is connected to free ends of the support structure and configured to store elastic energy when the support structure extends radially from its rest position. Upon rotation of the drive shaft, the resilient member stores both elastic and rotational energy commensurate with its mass and elastic properties.

A mechanical energy storage system, comprising:
- a containment vessel;
- a drive shaft operatively connected to a generator/motor and supported for rotation in the containment vessel;
- a support structure attached to the drive shaft and configured for radial extension from a rest position proximate the drive shaft;
- and
- a resilient member having a mass and extending circumferentially around the drive shaft, said resilient member connected to free ends of the support structure and configured to store elastic energy when the support structure extends radially from the rest position;
- wherein upon rotation of the drive shaft, the resilient member stores both elastic and rotational energy commensurate with the mass and elastic properties.
