Abstract:
A flywheel system for storing and releasing energy comprising:an inner rotor rotatable about a first axis; an outer rotor rotatable about a second axis which intersects on at least one dimensional plane with said fist axis, said outer rotor counter-rotating relative to said inner rotor; a first plurality of drive wheels positioned around said first axis and movable interfacing with said inner rotor and a first end of said outer rotor; and a second plurality of drive wheels positioned around said second axis and movably interfacing with said inner rotor and a second end of said outer rotor, wherein said outer rotor is a containment vessel for said inner rotor, and said outer rotor substantially surrounds said inner rotor in a radial direction and restricts debris from said inner rotor in a radial direction, and said first plurality of drive wheels and said second plurality of drive wheels substantially surround said inner rotor in an axial direction and restrict debris from said inner rotor in an axial direction.
