摘要： Efficiency of a horizontal axis wind/water turbine (HAWT) is increased by the addition of a secondary blade associated with each main blade. The secondary blade is preferably a blade segment paralleling the main blade only in the outer reach of the main blade. The secondary blade travels rotationally ahead of the main blade and axially behind it, in an area in which air has not been disturbed by the main blades and in which disturbance of air by the secondary blade is not seen by the main blades. In one embodiment the secondary blade is carried by its associated main blade. In another embodiment, the secondary blades are carried by a ring or wheel which rotates with the main blades and the axle to which they are attached.

摘要： The invention disclosed herein comprises a system focusing water current into a relatively smaller diameter lumen, imparting vortical movement to the current, and directing the water vortex through an even smaller diameter lumen en route to turbine blades having long curved blades rotatable along an axis parallel with the lumen. Rotation of the turbine blades turns gearing interfacing with the circumference of the turbine assembly, to rotate a drive shaft connected to a generator.

摘要： A hydropower system for generating electrical energy from water flowing along a bank includes a shaft configured to rotate about a vertical axis, an electrical generator configured to generate electrical energy in response to rotation of the shaft, and a first hydrokinetic device including a plurality of blades attached to the shaft and angularly displaced from each other around the axis. A portion of the first hydrokinetic device is submerged in the water within a cavity formed in the bank, and a portion of the first hydrokinetic device extends outside the cavity and is submerged within the flowing water. The flowing water pushes on the blades located outside the cavity, which drives rotation of the first hydrokinetic device and the shaft about the axis.

摘要： A buoyancy prime mover having a wheel rotating within a housing. An upper portion of the housing communicates with a lower portion of the housing through pipes and a blower. The blower pumps high pressure operating gas through a blower pipe into a lower portion of the housing. The housing contains operating liquid having a lower buoyancy than the operating gas. The wheel has a plurality of circumferentially disposed buckets. In operation, the blower pumps operating gas into the lower housing portion, where it bubbles up into the buckets. The greater buoyancy of the operating gas causes the wheel to turn. A venturi pipe connects a gas return pipe to to a venturi disposed within the lower housing portion. A venturi low pressure area pulls operating gas through the venturi pipe into the buckets, which also causes the wheel to rotate. At steady state operation, approximately half the operating gas in the buckets comes from the blower, and about half is pulled in through the venturi. The blower reduces the operating gas pressure in the gas return pipe and increases the operating gas pressure flowing into the housing. The operating gas in that portion of the wheel which is travelling upwards reduces the weight acting on that portion of the wheel and therefore creates a down pressure on that portion of the wheel which is travelling downwards, thus increasing speed and torque. The operating liquid weight in the buckets and the speed of the rotating liquid develop the main rotating power.
摘要翻译：具有在壳体内旋转的轮的浮力原动机。外壳的上部通过管道和鼓风机与壳体的下部连通。鼓风机通过鼓风机将高压操作气体泵送到壳体的下部。壳体包含比工作气体低的浮力的操作液体。轮具有多个周向设置的桶。在操作中，鼓风机将工作气体进入下壳体部分，在其中气泡进入桶中。工作气体的较大浮力导致车轮转动。文丘里管将气体返回管连接到设置在下壳体部分内的文丘里管。文氏管低压区域将操作气体通过文丘里管引入桶中，这也导致车轮旋转。在稳态操作中，桶中的大约一半的操作气体来自鼓风机，并且大约一半通过文丘里管被拉入。鼓风机降低气体返回管中的工作气体压力并增加流入壳体的工作气体压力。正在向上行进的车轮部分中的操作气体减小了作用在车轮部分上的重量，并因此在向下行进的车轮部分上产生了下压，从而增加了速度和转矩。铲斗中的操作液体重量和旋转液体的速度产生主旋转动力。

摘要： A method and apparatus for generating buoyancy power comprising harnessing the buoyant energy contained in hydrogen and oxygen gases which are electrolytically generated under water. A first wheel is submerged in water with a second wheel submerged vertically beneath the first wheel. An endless belt engages and is stretched between the outer surfaces of the first and second wheels and is adapted to rotate the wheels when the belt is driven. A power generator is coupled to one of the wheels and is drivable therewith. As the hydrogen and oxygen gas bubbles are generated at the respective submerged electrodes of an electrolytic generator, the rising bubbles are separately caught in two columns of receptacles along one side of the belt thereby displacing the water from the receptacles and rendering them buoyant. The buoyant receptacles then drive the belt and the first and second wheels thereby causing the power generator to produce an electric current. The hydrogen and oxygen gases are then separately collected in submerged hoods as they are released from the respective columns of buoyant receptacles as the belt and receptacles move over the first wheel. Also provided are two funnels for channelling the hydrogen and oxygen gas bubbles from the submerged electrodes to the respective columns of receptacles.
