  • Publication number: 20130270836
    Abstract: An apparatus, system and methods that on the one hand, maximise work done by gravity, by allowing free fall of an object with a heavy mass to harness energy and output therefrom, and on the other, maximises efficiency by counterbalancing this heavy mass by another similar mass such that only the net difference of the said two masses needs to be worked upon by input power mechanisms in order to lift the fallen object back up to its original position, along the direction of gravity or otherwise, to repeat the cycle. A plurality of such units are employed in synchronised tandem to maintain a steady RPM of the gear/flywheel/shaft connecting a high output generator. Still further, auxiliary energy generation mechanisms to further augment efficiency of the system are disclosed.

  • Publication number: 20130116850
    Abstract: Embodiments of the present invention relate to an approach for moving (e.g., lifting and lowering) objects (e.g., structures, cars, etc.) to generate and store energy to address energy shortage conditions. Specifically, the weight of an object is utilized to accumulate potential energy over a period of time through conversion of a source of energy (e.g. electricity) into potential energy when available power (i.e. supply) from the source of energy exceeds demand (e.g., an energy surplus condition is identified). This potential energy is then converted into another form of energy (e.g. electricity) over a period of time when excess power is needed (e.g., an energy shortage condition is identified).

  • Publication number: 20100126804
    Abstract: The buoyancy-gravity engine according to the present invention comprises buoyancy gravity rollers (1) which is constructed with specific dimensions and shape so as to perform its function effectively; a buoyancy chamber; a float regulation machine; a gravity machine with at least one wheel (3); a De-Pressure transfer box (9A); an interlinked BG roller (1) transfer mechanism; and a liquid compensator. The BG Roller (1) travels up and down through the buoyancy column and the gravity machine. When the BG roller (1) moves down in the gravity machine at least one wheel (3) of the machine is rotated due to the eccentric weight of the roller (1) in one end of the wheel (3). The roller (1) then slips down from the fingers of the wheel and rolls down to the mouth of the DP transfer box (9A). The roller is then pushed into the buoyancy column, and due to the inherent law of buoyancy, the roller (1) automatically reaches the top of the buoyancy column and again falls into the fingers of the gravity machine.

    Abstract: An electrical generator is driven by gravitational force provided by a plurality of pairs of water tanks. Each pair of water tanks is suspended by an elongated chain supported by a series of pulleys. The water tanks in each pair of water tanks move between an upper position and a lower position alternately by filling selected ones of the water tanks with water and draining from the other selected ones of the water tanks. The vertical movement of the water tanks alternately filled with water is translated by ratchet wheels and bevel gear wheels to rotate the electrical generator in the same direction for generating the electrical power.

  • Patent number: 6220394
    Abstract: A weight operated mechanical drive consists of a cylindrical weight that is suspended by a helically threaded drive screw which passes through and engages with complementary threads within a bore defined along a rotational axis thereof. The weight turns the drive screw as it falls due to the force of gravity. The weight is prevented from rotating about the axis of the screw while it is failing by a wheel which is attached thereto and which rolls against a retaining bar that runs alongside the weight along the weight's path of travel. The retaining bar is also used to wind the weight. To do so, the retaining bar is rotated around the rotational axis of the drive screw. This action forces the weight along a path defined by the helical threads of the drive screw. The retaining bar is formed as a helix around a column through which the weight drops.

  • Patent number: 4981014
    Abstract: A shell having a closed upper end and an open lower end, and a weight in the form of a piston sealingly slidable in the shell. In one form partial vacuum is produced in the shell above the weight and atmospheric pressure consequently raises the weight. In another form, pressurized air lifts the weight, against the action of weight. The weight has driving connection with a load, such as a generator, and upon being permitted to drop, acting by its potential energy, drives the load. The partial vacuum is produced in one form, by heating and cooling units; and in another form, by natural heating and cooling. A plurality of power plants are utilized to drive a single load, so that one weight can be raised, and the power plant re-activated, while others continue to drive the load, thereby maintaining continuity of drive.

  • Patent number: 4438656
    Abstract: An improved power transfer device utilizes an input power source supplemented by an unbalanced weight assembly which increases the torque on an output shaft as a function of load associated with the device. The input shaft is provided with a drive gear in operable engagement with an internal toothed ring gear, and the ring gear is provided with a plurality of diametrically opposed, radial extensions to which weight support arms are pivotably attached. The remaining free ends of the weight support arms are attached to the outer extensions of a cruciform support and are further in parallel alignment with and fixedly secured to elongated weights, such securement being offset from a central portion of the weights. A difference in load between the input shaft and output shaft results in the ring gear shifting in an unbalanced manner relative to the output shaft so as to deliver an additional torque to the shaft through the shifting of the unbalanced weights.
