Through dividing all blades into four or more blade groups including a certain number, which is three or more, of the blades, the blade located in the rearmost portion of each blade group in a direction of rotation is selected as a main blade, and remaining blades are selected as auxiliary blades, the length of each of the auxiliary blades is set to be shorter than the length of the main blade, and corresponding inner edge portions are positioned to the front, in the direction of rotation, of a normal line that passes through an outer edge portion of the blade, and an extension line of a chord line that connects the outer edge portion and the inner edge portion of the blade to one another are made to intersect with the main blade that is adjacent to the front in the direction of rotation.

Systems and methods related to floating powerhouse for hydropower turbine systems are presented. A turbine system may be coupled to floating powerhouse that can include a floating platform. A pressurized water delivery system can be coupled to the floating powerhouse and can accommodate vertical and/or horizontal movement of the floating power house. The pressurized water delivery system can include a segmented penstock coupling the turbine to an intake, and individual segments of the penstock can be free to rotate about a substantially horizontal axis, such that in response to variations in a tailwater height, the floating platform rising and falling does not disrupt fluid flow from a fluid source.

A turbocharger (10) having a compressor housing (15) and a bearing housing (17). The compressor housing (15) including an elliptical shaped wall (16) extending between an air inlet (11) and a volute (13) formed by the compressor housing (15). The bearing housing (17) forms a flat bearing housing wall (14) opposing the compressor wall (16) wherein the compressor wall (16) and bearing housing wall (14) form an elliptical diffuser (12) between the air inlet (11) and the volute (13).

Systems and methods related to linear turbine systems are presented. Each embodiment described herein may be designed as a single-stage, linear, impulse turbine system. In an embodiment, a linear turbine includes a first shaft extending along a first axis; a second shaft extending along a second axis, the second axis being separated from and substantially parallel to the first axis; a first plurality of buckets to travel a first continuous path around the first shaft and the second shaft along a first plane, the first path including a first substantially linear path segment between the first axis and the second axis; and a nozzle configured to direct a first fluid jet to contact the first plurality of buckets in the first linear path segment.

A wind compressor system having one or more wind turbines and a plurality of wind compressors located proximate the one or more wind turbines. The wind compressors optimize the energy created by the wind turbines by redirecting and converging the wind from the wind compressor to the wind turbines. Each of the wind compressors comprises an obstruction having a size and shape adapted to converge the wind currents by means of a Venturi effect toward the one or more turbines thereby increasing the velocity and force of the wind hitting the wind turbine. A plurality of transporters coupled to the wind compressors. The transporters configured to move at least one wind compressors to a location that maximizes the force of the wind encountered by the turbine.
