Patent ID: 8610300

Claim:
An energy generation device for harnessing gravitational and buoyancy forces present in a moving item comprising: a plurality of buoyant members; a first passage at least partially filled with fluid and configured to receive at least one of said buoyant members such that the buoyant member is free to move within said first passage due to buoyancy forces acting on said buoyant member; a second passage configured to receive the buoyant member from the first passage such that the buoyant member is free to move within said second passage due to gravitational forces acting on said buoyant member; a first transfer mechanism for transferring said buoyant member from said first passage to said second passage; a second transfer mechanism for transferring said buoyant member from said second passage to said first passage; and at least one generator responsive to said movement of the buoyant member within the first and/or second passage for generating electrical energy.
