An improved turbine over the old horizontal and vertical axis turbines because of its ability to capture several times the amount of wind. The basic design and process of this new machine can also work in the ocean at capturing ocean currents. Being Omni-directional (not having to turn into the wind) gives it one efficiency over the 3 bladed turbine. Another efficiency all embodiments have is its frictionless exponent. This quality helps save on wear and tear and maintenance cost. Most if not all past turbines have a static presents, being built in one basic wind capturing position. This new turbine is more dynamic because it can hide from wind damage and then open to capture more wind than its predecessors.

A wind turbine is optimized for low and high speed winds with sensing to measure climate change gases using IoT connectivity with long life serviceability. The wind turbine has an egg-shaped or elliptical profile that performs well in any physical orientation, enabling plural turbines in either horizontal or vertical stacks. A wildlife net is applied to the intake sides of the wind turbine, where the profile secures the net against displacement.

The vertical wind turbine and system generally comprises a rotor assembly having a plurality of blades, a fixed central spindle having a central axis for supporting rotation of the rotor assembly, a blade adjustment mechanism assembly for adjusting the blade angle of attack throughout rotation of the rotor assembly, and a support framework for supporting the rotor assembly at an elevated position in order to gain access to a sustained source of wind. The wind turbine may be operably coupled with a power electric generator or other device which transfers mechanical energy into electrical energy as a combined system.

The present invention teaches a vertical axis wind turbine including a base structure; a yaw system secured to the base structure; a rotatable turbine main body secured to the yaw system, a main shaft rotor including a plurality of vertical rotor blades secured to the main shaft rotor for the collection of wind energy located within the turbine main body, and an electrical control system to control the yaw system. The turbine main body includes a single spiral stator having a single vertically aligned opening. The yaw system rotates the rotatable turbine main body to align or not align the single vertically aligned opening with the wind.

In a vertical rotor apparatus that rotates in response to a moving fluid, a shaft defines an axis of rotor rotation. Rotor blades are longitudinally aligned in parallel with the shaft and each rotor blade defines an axis of blade rotation. A sensor generates a signal when any of the rotor blades are within rotor azimuthal angles of blade stall regions. A controller generates blade pitch information for the blade stall regions and an actuator, which is mechanically coupled to each of the rotor blades, alters blade pitch about the axis of blade rotation in accordance with the blade pitch information.

A rotor blade for a rotor having a vertical rotor shaft provides stream induced driving of the rotor in a direction of driving. The rotor blade includes streaming elements that are arranged successively and at a distance in the direction of driving, wherein each streaming element includes a front edge in the direction of driving and a rear edge in the direction of driving. The rear edge and the front edge are each formed such that, when streamed against by a wind component, it transmits a driving force to the rotor in the direction of driving. Furthermore, a rotor has a rotor blade and a system includes the rotor and an electric machine.

A fluidic rotor rotary machine has a rotor comprising at least one blade (4) mounted on an arm (2) rotating about a main axis (1) of the rotor, the rotor being held by a support structure (5) in an orientation such that said axis (1) is essentially perpendicular to the fluid flow direction, the blade (4) being pivotally mounted about a rotational axis (3) parallel to the main axis (1), the machine being characterized in that it comprises means for generating a relative rotational movement of the blade (4) relative to the arm (2) at the rotational axis (3), thereby varying the blade angle, said means comprising an eccentric mechanism rotating on said blade rotational axis. Application in particular to propellers and generators operating according to Lipp-type or Voith-Schneider-type kinematics, with possible mode switching.

A device and method of acquiring mechanical energy by using a wind power generator employing sails is described. A sail is mounted on a towing carriage that is used for the rotation of a propulsion wheel of the mechanical gear is added. The towing carriage is connected to a strand and the strand transfers the force originated by the sail to the propulsion wheel of the power plant. The sail has the ability of adjustment of its angle position to the direction of the wind, the total exploitation cycle of the wind power generator employing sails consists of the working part during which the sail is moving along the direction of wind.

A present invention describes unique wind turbine assembly in a shape of closed hollow cylinder formed by two sets of three adjustable to positive and negative pitch horizontal blades supported instead of central shaft by three vertical cylindrical blades, which makes this turbine responsive to omni-directional wind. Proposed design concept provides with: Significant increase of turbine efficiency exceeding 60%, which after coupling this rotor with a generator of 60% efficiency leads to overall wind generator efficiency exceeding 40%. Low turbine inertia requiring moderate start up winds and reducing turbine vibrations. Noiseless turbine operation due to its rotation around vertical axis. Environmental friendliness as low operating speed does not generate strong turbulent air flow capable to challenge birds and bugs existence. No electronic control of blades angle of attack. Ease of manufacturing and maintaining together with their reduced cost.
Conducted analysis of the proposed configuration of the wind turbine shows no necessity of additional top support for a personal use wind generator, while requires one for more powerful (community) wind turbines. Proposed additionally supporting turbine tetrahedron beam frame resolves this issue allowing increase of power of such wind generators.
