Wind turbines for vertical wind turbines, that is, self-adjusting stationary blades and wind routers which further enhance the operation and efficiency of each wind turbine on the main axis of the turbine. Depending on the height of the turbine, there may be one or more routers, depending on the height of the turbine, taking into account the rotor height of about 3 meters, it would have 3 wind routers of 1 m each.

A wind powered turbine is disclosed that comprises two concentric cylinders. The first cylinder is located within the perimeter of the second cylinder. Both the first cylinder and the second cylinder comprise a plurality of blades. The first cylinder and its blades move in response to wind activity. The second cylinder and its blades do not move when the first cylinder and its blades are moving. The curvature of the blades of the first cylinder and the curvature of the blades of the second cylinder are in different directions with respect to each other.

The wind turbine comprises a rotor which rotates with respect to a stator about a rotation axis. The rotor comprises at least one narrow blade and at least one wide blade fixed with respect to one another, and the lateral extension of the wide blade is at least 1.5 times that of the narrow blade.

A Savonius-type rotor assembly is improved by utilizing a plurality of blades, shaped and interconnected by a plurality of shaped surfaces, forming a rotor shell exposed to a flowing fluid that efficiently redirects the surface flow along each shaped surface directly against the flowing fluid at its blade tip as each blade tip is pointed directly into the flowing fluid. Each shaped skin surface has a concave section and a convex section. The concave section of each shaped surface forms the concave portion of one blade, and the convex section of the same shaped surface forms the convex portion of an adjacent blade. On a cross-sectional plane perpendicular to the rotor axis, each shaped surface follows an s-shape, and the concave section substantially follows an Euler spiral segment that is tangent at its outer end to the circumference of the rotor.

A wind power collection device, a gas storage device, and a power generation system, where the wind power collection device includes an impeller, an outer side wall of the impeller is composed of four mutually spliced flow guide surfaces, radial cross sections of the four mutually spliced flow guide surfaces correspond to four mutually spliced flow guide curves, the flow guide surfaces are formed by rotating and stretching the flow guide curves around an axis line of the impeller in an axial direction; and the flow guide curves include a segment of convex first logarithmic spiral line and a segment of concave second logarithmic spiral line, and the first logarithmic spiral line and the second logarithmic spiral line of the flow guide curves are smoothly and transitionally connected at one side close to the axis line.

A vertical-axis turbine extending longitudinally along an axis of rotation is disclosed, wherein the turbine has first and second blades disposed around the axis of rotation, the first and second blades having proximal portions and distal portions located relatively close to and away from the axis of rotation respectively, and body portions located between the proximal portions and the distal portions. The turbine also has a rotor assembly coupled to an end of the first and second blades. The proximal portion of the first blade contacts the body portion of the second blade and the proximal portion of the second blade contacts the body portion of the first blade to form a closed volumetric region around the axis of rotation. The shape of the first and second blades may be defined by twisting a sheet of flexible material according to a frame comprising two or more pairs of battens.
