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： 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.

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 hybrid metal and composite spool includes metal rings on an outer diameter of a composite spool shell. Metal rings may include features such as annular or axial dovetail slots. Adhesive layers may be between the metal rings and composite shell which may be connected by a shrink bonded joint. The metal rings may include a single seal tooth ring with an annular radially extending seal tooth. A method for fabricating the spool may include fabricating one or more metal rings with the features therein, positioning the metal rings in place on an outer surface of an uncured composite spool shell of the spool before curing the shell, and curing the shell with the one or more metal rings positioned in place. Alternatively, rings may be heated to a temperature at least sufficient to slide rings over a cured composite shell, and allowed to cool and shrink onto shell.
