A turbine, in particular for harvesting energy in flowing air or flowing water, is easily adaptable to different application conditions and facilitating a comparably high degree of efficiency. This is achieved in that the basic shape of the turbine is cylindrical and is provided with blades which are parallel to an axis of the turbine. The blades are pivotally arranged in joints on the outer circumference of at least one turbine wheel. The blades are substantially L-shaped. The longer limb of the blade is curved preferably in a manner corresponding to the radius of the turbine casing, and the shorter limb lies within the surface line of the turbine.

The invention relates to a floatable hydroelectric generator (10) for harvesting electrical energy from the flow (R) of water in a river. The generator assembly (10) includes a floatable chassis (12) to which are connected two spaced-apart rotational axles (18). An electrical generator (not shown) is mounted on the floatable chassis (12) and coupled to the rotational axles (18). A chain (20) is connected to the rotational axles (18) via pulley wheels (16). A plurality of water receptacles (22) are fixed to the chain (20), and each being orientated, when submerged, to present their major openings towards an oncoming waterflow direction (R). A plurality of minor openings (24) is provided through a wall of each water receptacle (22). A valve member in the form of a flexible flap (26) is located within each water receptacle (22) for controlling passage of water through said minor openings (24). The flexible flap (26) is adapted to selectively permit flow of water through the minor openings (24) into each water receptacle (22); but substantially prevent flow of water through said minor openings (24) out of each water receptacle (22). The generator assembly (10) of the present invention may be deployed at a desired location within a river—optionally as part of a larger array of such assemblies—to generate electricity on a substantially continuous basis.

An improved turbine over the old horizontal and vertical axis turbines because of its ability to capture several times the amount of wind. The basic design and process of this new machine can also work in the ocean at capturing ocean currents. Being Omni-directional (not having to turn into the wind) gives it one efficiency over the 3 bladed turbine. Another efficiency all embodiments have is its frictionless exponent. This quality helps save on wear and tear and maintenance cost. Most if not all past turbines have a static presents, being built in one basic wind capturing position. This new turbine is more dynamic because it can hide from wind damage and then open to capture more wind than its predecessors.

An gas-driven generator system for generating electric power from movement of a working liquid. The system includes a gas-driven generator that includes a liquid turbine system fluidically interposed between the lower end of an elongated gravitational distribution conduit and the lower ends of plural elongated buoyancy conduits. A heavy working liquid flows from the upper ends of the buoyancy conduits and is fed into the upper end of the elongated gravitational distribution conduit. Working liquid flows down the elongated gravitational distribution conduit to actuate the liquid turbine system. An injection of refrigerant gas into the working liquid in the plural elongated buoyancy conduits induces upward flow of the working liquid. The system includes a solar thermal heating system fluidically coupled to heat exchangers that transfer heat collected by the solar thermal heating system to the working liquid through a thermal transfer fluid circuit.

A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. The pump incorporates an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.
