A rotor including soft rotor structures fixed to the rotor shaft, which rotor structures are of a soft material such as canvas or the like. The rotor structure is a loop arranged to form an asymmetrical cone when an air or water current flows through the loop.

A rotary device that converts a linear fluid movement to a rotational fluid movement to generate power includes a front sail and a plurality of sail pairs situated around a shaft. In some embodiments, each of the sail pairs includes oppositely disposed sails in the same longitudinal plane. In some embodiments, the front sail and/or each sail of the sail pairs can include a flap and/or an airfoil.

A traction mat system and a method of manufacturing comprising a mat having a grip layer adhered to or mate integral to the surface of the mat. The grip layer can be a textured material foil sheet combined to a top surface and/or a bottom surface of the mat system. The texture of the grip layer is retained when the mat is contoured with a raised pattern to give the entire surface of the mat a texture to improve traction and grip. A method of manufacturing comprises a traction mat system wherein the traction mat can comprise of manufacturing step for placing a grip layer on the mat surfaces, for placing the foil sheet and/or aggregate on the mat. Each operation can be performed for both surfaces simultaneously or can be its own operation such as one surface at a time, or both surfaces at once.

A turbine system includes a shaft extending along an axis. A first spoke has a first end, attached to the shaft, and a second end. A second spoke has a first end, attached to the shaft, and a second end. A third spoke has a first end, attached to the shaft, and a second end. A turbine blade is attached to the second end of the first spoke, the second end of the second spoke, and the second end of the third spoke. The turbine blade extends continuously circumferentially about the axis. The turbine blade is spaced a distance apart from the axis and in non-contact with the shaft.

The present invention is an improved wind turbine comprising: a wind turbine wheel having a hub, a rim and a cable extending between the hub and the rim; a set of airfoils rotatably carried by the cable and disposed between the hub and the rim; a cinch attached to the cable and disposed between adjacent airfoils; and, an upturned section included in at least one airfoil in the set of airfoils and disposed at a trailing edge of the airfoil wherein each airfoil has a different angle of attack relative to an adjacent airfoil.

A tension airfoil assembly includes an outer rim located concentrically with a hub supported by a plurality of spokes, each spoke extending therebetween. A series of airfoils, each airfoil having an aerodynamically lifting shape extending between a leading edge and a trailing edge. Each airfoil of the series of airfoils is assembled to the tension airfoil assembly by coupling an area of the airfoil proximate the leading edge to a leading edge spoke and an area of the airfoil proximate the trailing edge to a trailing edge spoke. The airfoils are arranged having a gap provided between the trailing edge of each forward located airfoil and the leading edge of each trailing located airfoil. The tension airfoil assembly can be employed as a propulsion and/or lifting device integrated into a vehicle, such as an airplane, a helicopter, a tandem rotor helicopter, etc.

A rotor (10) for power driving includes a hub (12), a plurality of fixed jibs (14), and a plurality of vanes (16). The hub (12) is adapted to be coupled with a mechanical shaft (24) which is driven by winds, water flows or tides as driving sources. The fixed jibs (14) are arranged around the hub (12) circumferentially and spaced from one another. Each fixed jib (14) extends in a radial direction perpendicular to an axial direction of the shaft (24). Each vane (16) is elastically fixed at one of the fixed jibs (14) such that the vanes (16) on which external forces act are elastically movable relative to the fixed jibs (14) and rebound after removal of the external forces.

The present turbine is intended for use in the field of renewable energy. The turbine comprises a rotor with a guide apparatus disposed thereon, said guide apparatus having inlets for a working fluid which are in the form of ducts that spiral around each other in helices and have nozzles situated along a tangent to the circle of rotation. The guide apparatus is configured in the form of adjacent ducts which are open along their entire length or along at least a significant portion of their length and are situated on second order surfaces of revolution or on portions of such surfaces, and in particular on convex-concave surfaces of the pseudosphere type with a cone in the pole of an axial cowl of the rotor. The result is in simplification of the structure and reduction in the turbine mass, the gyroscopic effect and the starting speed of the working fluid.

A wind control blade (31) of a wind guide (30) of the present invention forms a 20 wind control blade lateral curved surface gradient angle (32), a 30 wind control blade longitudinal spiral twist angle (33), a 180 wing control blade alignment angle (34), and a 15 wind control blade rear gradient angle (35). In addition, a turbine blade (41) forms a 30 turbine blade lateral curved surface gradient angle (42), a 40 turbine blade longitudinal spiral twist angle (43), and a 120 turbine blade alignment angle (44). The 20 wind control blade lateral curved surface gradient angle (32) and the 30 wind control blade longitudinal spiral twist angle (33) of the wind control blade (31) have more gradual and wider incidence angles than the 30 turbine blade lateral curved surface gradient angle (42) and the 40 turbine blade longitudinal spiral twist angle (43) of the turbine blade (41). Accordingly, since more wind enters into the central direction of the inner side of the turbine blade (41) and a primary whirlwind is generated, much higher acceleration can be obtained.

The present invention is an improved wind turbine comprising: a wind turbine wheel having a hub, a rim and a cable extending between the hub and the rim; a set of airfoils rotatably carried by the cable and disposed between the hub and the rim; a cinch attached to the cable and disposed between adjacent airfoils; and, an upturned section included in at least one airfoil in the set of airfoils and disposed at a trailing edge of the airfoil wherein each airfoil has a different angle of attack relative to an adjacent airfoil.
