The 3D ultrasonic anemometer includes: an ultrasonic sensor including three pairs of ultrasonic transceivers arranged in different directions, wherein the ultrasonic sensor is installed at a rotation body rotating around a rotation axis and rotates around the rotation axis together with the rotation body; a signal processor outputting a 3D sensed wind velocity sensed by the ultrasonic sensor; and a coordinate converter converting the 3D sensed wind velocity into a 3D fixed wind velocity on a fixed coordinate system by using a rotation angle of the rotation body.

A combined omnidirectional flow turbine system includes rotors that are disposed in a vertical position and enclosed in a motionless structure that receives air flows from any external direction which are manipulated by an airfoil to cause the rotors to rotate. The motionless structure is a hollow body and it is formed by a support structure and cover, being said interior space adapted to store electronic components, which can be directly supplied by the energy, produced. On its outer surface, air particles and pollutants filters can be installed, taking advantage of the aerodynamic shape of the motionless structure, which promotes air flow adhesion along its surface, making possible to capture particles along their preferred path.

A third arc connected to the second arc having a radius of 0.4636 inches and an arc length of 0.1682 inches. A fourth arc connected to the third arc having a radius of 0.3822 inches and an arc length of 0.2263 inches. A fifth arc connected to the fourth arc having an arc having a radius of 0.3291 inches and an arc length of 0.1917 inches. The fifth arc of each side forming the slot end on the clip.

Provided is a wind power installation for converting the kinetic energy of the wind into the mechanical energy of rotation of a rotor for subsequent conversion of the mechanical energy of rotation into the electrical energy. A wind power installation includes a support frame, a shaft disposed on the support frame, and a blade system mounted on the shaft. The shaft is configured to rotate about a vertical axis and is functionally connected to an electric generator. The support frame is configured to be mounted between at least three radially arranged structures. The wind power installation can include additional blade systems disposed one above another on the shaft. Mounting the support frame between three radially arranged structures results in greater rigidity and robustness of the wind power installation, thus enabling the use of blade systems having a larger blade area and the arrangement of several blade systems on the shaft.

There may be provided a wind power system that may include a turbine that comprises multiple curved blades that rotate about a vertical axis; wind collectors that surround the turbine; wherein each wind collector comprises a set of facets that define an outlet and an opening that is bigger than the outlet; wherein the outlet faces the turbine; and a ventilation mechanism.

A vertical axis wind turbine includes a cylindrical rotor with a plurality of convex-concave blades placed in a stator which directs the wind stream. The VAWT is installed vertically towards a surface of the ground, and wherein, the stator and the rotor are formed of vertically located blades which may have numerous geometric forms. Both the stator and rotor blades have a leading edge and a trailing edge, and each blade of the stator possesses a top end that is fastened to an immobile upper plate of the stator, and a bottom end that is fastened to a lower plate of the stator. In this embodiment, each blade of the rotor includes a top end fixed to an upper plate, while a bottom end of the each blade is fixed to a lower plate.

A wind turbine having at least two blades mounted to a blade retainer and a load shaft connected to the blade retainer, such that movement of the blades due to wind causes rotation of the load shaft. The wind turbine includes a frame assembly surrounding the turbine assembly. The frame assembly includes a plurality of vanes to direct wind inside the frame assembly and towards the blades of the turbine assembly. The vanes have a half circle shaped leading edge pointing to an outside perimeter of the frame assembly. The half circle leading edge has two ends and the vanes have a side extending from each of the ends of the half circle that come together to form a trailing edge.

In a method for generating electricity from an apparent wind turbine, a compressor compresses air into compressed air storage to be released at a later time to operate the apparent wind turbine. The method contemplates determining a minimum energy production threshold and a desired energy production threshold, detecting that energy generation from the apparent wind turbine falls below the minimum energy production threshold, and causing the apparent wind turbines to produce at least the minimum energy production threshold.
