    摘要: A fluid turbine may include a vertically-orientable shaft having at least one opening extending transversely therethrough, a first blade portion configured for vertical orientation on first side of the shaft, a second blade portion configured for vertical orientation on a second opposite side of the shaft, at least one rod extending through the shaft opening and connectable at a first end to the first blade portion and at a second end to the second blade portion. A reinforcing sleeve may extend through the shaft opening and may be interposed between the rod and the shaft opening for reinforcing at least one of the shaft, the at least one shaft opening, or the rod against forces exerted by the first and second blade portions when fluid impacts the first and second blade portions.

    摘要: A coupling system for coupling a curved object to a central shaft, the curved object includes an inner surface facing the central shaft and an outer surface. The system includes a coupling member for coupling the curved object to the central shaft; at least one pocket integrally formed on a curved surface of the curved object and defined as a depression with respect to at least one of the inner and outer surfaces. The pocket includes: a flat portion having an aperture for holding the coupling member; and a flange portion which merges continuously from the flat portion to the curved object and is shaped such that the flat portion is disposed perpendicularly to the coupling member; a fastening member for fastening the coupling member to the flat portion. The thickness of the flat portion and flange portion is the thickness of the curved object.

    摘要: An industrial structure for wind energy harvesting includes an industrial housing requiring venting and a vent outlet, An industrial fan associated with the vent outlet evacuates exhaust, forming an exhaust flow zone opposite the vent outlet. The exhaust flow zone is defined by first and second boundaries extending from the industrial structure on first and second sides of the vent outlet. At least one wind turbine is positioned external to the vent outlet including a turbine blade portion and an electric generator. The at least one wind turbine is positioned with respect to the vent outlet such that during each rotational cycle, the blade portion is partially within the exhaust flow zone and partially outside the exhaust flow zone straddling the first boundary.

    摘要: Systems, methods, and computer program products are disclosed for determining a power curve for a fluid turbine. Determining a power curve for a fluid turbine includes receiving an indication of a fluid speed condition; if a predetermined load compliant with an MPPT protocol for the fluid turbine operating under the fluid speed condition is available, obtaining the predetermined load; and applying the predetermined load to the fluid turbine, thereby adjusting a rotational velocity in accordance with the MPPT protocol and the fluid speed condition; if the predetermined load is unavailable, applying a plurality of candidate loads in an iterative manner in accordance with the MPPT protocol and the fluid speed condition; determining an MPPT-compliant load that generates greater power; applying the MPPT-compliant load to the fluid turbine; and storing the MPPT-compliant load in association with the fluid speed condition for subsequent application.

    摘要: A flat-packable wind turbine assembly kit, includes a flat-packed bendable airfoil having an upper edge and a lower edge. The flat-packed bendable airfoil is capable of assuming a predefined curvature upon assembly. The flat-packed bendable airfoil includes upper connecting elements distributed along the upper edge and lower connecting elements distributed along the lower edge of the flat-packed bendable airfoil. The flat-packed bendable airfoil also includes a flat-packed upper plate including an upper mating orifices distributed in a contour corresponding to the predefined curvature. Further, the flat-packed bendable airfoil includes a flat-packed lower plate including lower mating orifices distributed in the contour corresponding to the predefined curvature. Thus, upon assembly when the upper connecting elements are connected to the upper mating orifices and when the lower connecting elements are connected to the lower mating orifices, the flat-packed bendable airfoil assumes the predefined curvature.

    摘要: System, methods, and computer readable medium are disclosed for altering orientation of fluid turbines within a cluster. Altering orientation of fluid turbines within a cluster includes a first turbine assuming a first orientation relative to a direction of fluid flow; a second turbine in proximity to the first turbine, and assuming a second orientation relative to the first orientation, wherein the first and/or second orientations are adjustable to mitigate interference with downstream turbine operation; a processor for receiving an indication that the first turbine imposes interference on the second turbine; based on the indication, determine a third orientation enabling the first and second turbines to produce greater aggregate electrical energy than would be produced with the first turbine in the first orientation and the second turbine in the second orientation; and transmit a signal for changing one of the first and second orientations to the third orientation.

    摘要: Systems, methods, and computer readable medium are disclosed for coordinating rotation of adjacent turbines. Coordinating rotation of adjacent turbines includes receiving first rotational orientation information from a first turbine having a first open concave surface and corresponding convex surface; receiving second rotational orientation information from a second turbine having a second open concave surface and corresponding convex surface; receiving fluid flow direction information relative to the first and second turbines; calculating a rotational speed adjustment to cause, at instantaneous times, the first and second open concave and corresponding convex surfaces to be simultaneously transverse to the direction of fluid flow; outputting a control signal embodying the rotational speed adjustment to thereby regulate rotation of the first and/or second turbines such that at the instantaneous times, the first and second open concave and corresponding convex surfaces are transverse to the direction of fluid flow.
