Abstract: A device for generating substantially vertically-reciprocating motion uses a plurality of chambers in substantial vertical alignment. Each chamber has an air pocket and a buoyant member which floats at the air/water interface, and such air pockets expand and contract upon receipt of additional amounts of air from below and release of some of the air, usually to a chamber above. As the air pockets expand and contract, the interfaces are raised and lowered, and the buoyant elements are raised and lowered with the interfaces. A method uses such device to generate such reciprocating motion, which optionally may be used to drive electric generators.

Abstract: A hydraulic power device is provided. The hydraulic power device includes: a first cylinder with a cylindrical chamber, a first fluid inlet, a first fluid outlet, and a weight unit having a first piston. The first piston hermetically fits into the first cylinder and moves upwards and downwards within the first cylinder. When the first piston moves downwards within the first cylinder, the fluid in the cylindrical chamber flows out through the first fluid outlet under the pressure from the first piston, and thereby generates hydraulic power. When the first piston moves upwards within the first cylinder, the fluid flows into the cylindrical chamber through the first fluid inlet, to get prepared for subsequent hydraulic power output. The hydraulic power device in the present invention is designed to lift a weight unit with a small initial power and then generate hydraulic power utilizing the gravity of the weight unit.

Abstract: An apparatus comprising the use of at least two or more vertically disposed tubular structures with each tube filled with water, and having a nozzle-like conduit at one end. Inside each tube is a sealed cylinder or float for containing either gas or water. When gas is introduced into the float positioned at the bottom of the tube, the float begins to ascend inside the tube causing the water advancing ahead of the rising float to become increasingly more pressurized due to the buoyancy effect. Maximum or near maximum pressure levels are reached when the water advancing ahead of the rising float reaches the top of the tube and is forced through the narrow conduit and the interconnected flow line. At the top, the gas in the float is replaced with water compelling the float to sink to or near the bottom of the tube where the water is replaced with gas, and the process is repeated.

Abstract: A method is invented for converting heat in a liquid to power and generating thermal difference of the heat source liquid between the inlet and the outlet of a machine. The heat source liquid (8) is drawn to the lower right side of the cylinder (1) through the inlet (5). The heat in the heat source liquid (8) boils the working liquid (2) at the right side of the cylinder (1).

The buoyant force on the right and the gravitational force on the left of the cylinder (1) rotate the cylinder (1) to produce power. As heat is transferring to the cylinder (1), the temperature of the heat source liquid (8) is lower at the outlet (4).

This rotation drives the energy generator and generates energy, preferably electricity. The cog wheels are permitted to rotate upon the receipt of a request for energy. This results in a highly efficient source of energy or electricity.

Abstract: In accordance with the present invention, a portable wave-swash & coastal-wind energy harvester, once placed on a sea coast in the swash zone captures the mechanical energy contained in: (a) waves in the swash-zone, and (b) coastal-wind.

Abstract: A tidal power generator has a floating vessel hull that is subject to rising and falling water levels so that the hull moves vertically up and down. Linear-to-rotary converters are coupled between the vessel hull and a fixed object. The converters allow the hull to move vertically while constraining the horizontal movement of the hull.

A harborage is provided to protect the hull and the converters and to regulate the water level for the vessel hull as well as become a fixed object relative to the vessel from which a change in relative position causes power to be developed. If the hull is subject to tidal variations, vertical movement of the hull can be desynchronized from the tidal variations so as to store energy during slack tides.

In an exemplary embodiment, the buoyancy engine includes a divider to separate a liquid environment from a gas environment, and a reservoir aperture in the divider. A rotating element, approximately opposite the reservoir aperture, provides tension to, and helps rotate, a segmented chain.

As the segmented chain travels between the liquid and gas environments, a rotary motion is created which can be captured as electrical or mechanical energy.

Abstract: An engine includes a liquid reservoir and a wheel mounted for rotation about a central shaft. Float members are supported symmetrically about the wheel for rotational movement and for movement toward or away from the central shaft. Each float member is coupled with a diametrically opposed float member on an opposite side of the wheel by a connecting rod. A camming surface urges passing float members toward the central shaft, and simultaneously urges a diametrically opposed float member away from the central shaft. The wheel rotates as a result of an imbalance in the buoyant forces created by the float members. Magnetic forces can supplement the camming surface for moving the float members toward and away from the central shaft.

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: FES was created to protect Earth's atmosphere by improving efficiency of electricity facilities and enabling non-electricity producing reservoirs contribution to electrical demands! FES is an efficient pneumatic torque/rpm drive joinable with Geothermal, Hydro, Solar, Wind or other electricity generation systems can potentially increase their efficiency. FES Alpha prototype was tested by Prof. Tennyson Phd. and Hatten M. E. (BSU) in 2008. Dr. R. Reiman (BSU) and Prof. R. Adrian (M.A./E @ ASU) were consulted regarding the fuel conversion efficiency data. The FES Alpha prototype buoyant air fuel input lb/sec. value was 3.639792 lb/sec. The FES system's output shaft @ 1.66 rp/sec. was opposed by 10.91 lb/sec. This is a 299% energy efficiency conversion. It's achieved by replenishing stored and recycled energy within the FES like the trickle charge to a battery. The FES was re-engineered for this patent eliminating inertial losses and could have input/output efficiency ratios as high as 1:6 or more.

Abstract: The present disclosure relates to an apparatus and associated methods for generating energy by capturing and taking benefit of the energy generated by any quantity of air surfacing inside water. The apparatus includes a frame structure to which is rotatably mounted an upper drive wheel, a lower wheel, and a vertical fluid column container. An endless chain of gas capsule elements is mounted on the upper and lower wheels. This endless chain passes vertically up into and through the fluid column container through a seal port in the bottom of the container. As the endless chain of gas capsule elements passes vertically through the fluid in the container, fluid pressure on the elements due to the height of the column of fluid in the container produces a net buoyant force upward on the elements, causing them to rise, generating kinetic energy that turns the wheels.
