摘要： A sealing system for a Gravity Power Plant having a shaft (104) with a shaft wall (105) and a piston (102) incorporates a seal assembly support base (202) anchored into the shaft wall and surrounding the piston. A seal mount has a radial flange (210) to anchor the seal mount to the support base (202) and a vertical flange (212) extending from an inner circumference of the radial flange. A seal assembly (206) circumferentially contacting the piston, has a plurality of circumferentially spaced clamp assemblies (227) to engage the seal assembly to the vertical flange, the clamp assemblies having an open position releasing the seal assembly from the vertical flange and a closed position constraining the seal assembly on the vertical flange. For seismic isolation of the seal assembly the radial flange is supported on a lower bearing (406) supported on a top surface of the seal assembly support base proximate an inner surface. The radial flange (410) extends inward from the inner surface with the vertical flange spaced from the inner surface by a radial relief (428) within a gap between the seal assembly support base and the piston. An upper bearing is supported in engagement with a top surface (411) of the radial flange (410) of the seal mount (404).

摘要： An energy storage and delivery system includes an elevator cage, where the elevator cage is operable to move one or more blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move one or more blocks from the higher elevation to the lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The blocks are moved between the lower elevation and the higher elevation by an equal vertical distance.

摘要： An energy storage and delivery system includes one or more cableways and a cage that travels along each of the one or more cableways. The cage is coupled (e.g., fixedly coupled) to one or more cables that extend between a lower elevation and a higher elevation, the cables or steel ribbons being translated along the associated cableway by a traction motor wheel to translate the cage along the associated cableway. The system is operable to pick-up, transport and deliver with the cage a plurality of blocks from the lower elevation to the higher elevation to store energy (e.g., via the potential energy of the block). The system is also operable to pick-up, transport and deliver with the cage a plurality of blocks from the higher elevation to the lower elevation at least partially under force of gravity to generate electricity via an electric generator coupled to the traction motor wheel.

摘要： An energy generating device may include a first body portion with at least one first force input structure coupled to the first body portion and configured to receive an external force. The energy generating device also may include a second body portion, the second body portion rotatable relative to the first body portion. Further, the energy generating device may include an electrical generator configured to use the relative motion between the first body portion and the second body portion to generate electricity. The first body portion and the second body portion are configured to descend through a medium at least partially under the force of gravity or ascend through the medium at least partially by buoyant forces in such a way that the medium causes a force on the at least one first force input structure by impinging on the at least one force input structure causing relative rotation between the first body portion and the second body portion. An energy generating device may include at least one first body portion, at least one second body portion, at least one torque generator configured to cause relative rotation between the first body portion and the second body portion, and at least one electrical generator configured to use the relative motion between the first body portion and the second body portion to generate electricity, wherein the first body portion and the second body portion are configured to descend through a medium at least partially under the force of gravity or ascend through the medium at least partially by buoyant forces in such a way that the torque generator causes relative rotation between the first body portion and the second body portion.

摘要： An apparatus for generating electrical power, comprising: a generator for generating electrical power; a handle having a first end that is rotatably coupled to the generator, and a second end that is rotatable 360 degrees about the generator in a substantially vertical plane from a top dead centre (TDC) position, through a bottom dead centre (BDC) position, and back to the top dead centre (TDC) position; a weight that is moveable along the handle between a first position, a piston arranged to move the weight between first and second positions. The piston being operable to move the weight along the handle from the first position to the second position, such that the weight provides a mechanical advantage as the handle rotates from TDC to BDC due to gravity acting on it, whereby rotation of the handle drives the generator thereby to generate electrical power. A corresponding method is also provided.

摘要： An energy storage system stores power received from a power grid as potential energy in compressed earth materials. The energy storage system includes a motor-generator coupled to an anchor via a tensile member. The motor-generator is configured to apply a tensile force to the tensile member. The tensile force causes the motor-generator and the anchor to apply a compression force to the earth materials in the ground, and causes the anchor to displace, thereby storing the received power as potential energy. The energy storage system provides power to the power grid by relieving some of the tensile force on the tensile member and thereby relieving some of the compression force on the earth materials. The anchor displaces towards its original position, and thereby causes the motor-generator to generate electrical power from the stored potential energy.
