摘要:
The present invention relates to a hydroelectric power generator for a river. More particularly, the hydroelectric power generator for a river, while being installed in a river or in water stored by a dam, can induce the flow velocity of water inside a turbine system and produce power using the rotating turbine, can use environment-friendly energy by controlling the amount of water flowing inside, can be installed at various places including a place with a small head drop, and can be configured in various sizes.

A tidal stream impeller generator. The generator is a closed container, housing generators and related equipment in a non-flammable environment. The generator housing has affixed to it impeller blades, oriented to maximize the force captured from the movement of seawater with tides at depth. The housing and impeller blades rotate about a conduit, the conduit serving as an axle as well as a conduit for cables, pipes, and related structures to enter the housing without breaching the watertight housing. The conduit passes through end caps on the housing, through watertight bearings.

Some embodiments of a turbine system described herein provide a turbine that rotates in response to off-axis fluid flow, such as water flowing in a generally horizontal direction that is generally perpendicular to a vertical axis of rotation. The rotation of the turbine can drive a generator to output electrical energy.

A centrifugal impellers structure is mounted to a transportation vehicle that has a wheel and a wheel hub and includes first and second centrifugal impellers. The first centrifugal impeller is in operative coupling with a free wheel hub axle mounted to the wheel hub and includes a top plate and a bottom plate, between which blades are mounted. The plates each form at least one inlet. The blades are arranged not to shield and block the inlets and define therebetween channels communicating with the inlets. The second centrifugal impeller is coupled to a rim of the wheel and includes a top plate and a bottom plate, between which blades are mounted. When the first and second centrifugal impellers are caused to rotate, the first centrifugal impeller generates an aerodynamic force that drives the second centrifugal impeller and the second centrifugal impeller generates a rotary force to drive the wheel.

摘要:
An auger shaped, fluid medium engaging member is disclosed which includes a helically or auger shaped outer region disposed about a longitudinal axis which passes through a central region of the member. The auger shaped outer region establishes at least one auger or helically shaped fluid medium engaging surface, which intercepts the flow of a fluid medium such as air or water, for effecting rotational movement of the fluid medium engaging member about its longitudinal axis. The auger shaped, fluid medium engaging member may be coupled to an electrical generator, for generating electrical energy upon rotational movement.

A hydraulic/pneumatic turbine transmission (10) for converting a pressurized fluid source (26) to rotary motion of variable torque and rpm is disclosed. Turbine transmission (10) generally has housing (12) including main body housing (12a) and front housing cover plate (12b). An output shaft (11) is rotatably secured within housing (12) and has a main turbine runner (16) radially attached thereto. Main turbine runner (16) includes a plurality of concentrically disposed subrunners of progressively smaller diameter. A pair of diametrically disposed variable position nozzles are provided and disposed within housing (12) to selectively supply pressurized fluid to any one of the plurality of subrunners. A plurality of arcuate scavenge ports (33) are provided within housing (12) to allow a pressurized fluid to exit subsequent to impact on main turbine runner (16). Variable position nozzles (23) can be independently controlled to produce 2x-1 output speeds, where x is equal to the number or subrunners.
