A vertical axis wind turbine (VAWT) with improved and optimized wind-directing, wind-shaping, and wind-power conversion features is disclosed. The shapes of these features directly affect the ability of the VAWT to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency of the invention is significantly improved over previous efforts, to the point that the invention can convert wind energy into electrical power at a price-to-performance ratio that competes with or surpasses existing alternative energy technologies.

A turbine engine system includes a fire chamber and a helical fan. The fire chamber includes a first cylindrical body having a first central axis; a first elongated hollow shaft extending co-axially along the first central axis; a plurality of wings fixedly secured to an exhaust plate and the first elongated hollow shaft; a plurality of combustion chambers disposed within a thickness of the first cylindrical body; a plurality of fuel injectors; and a plurality of spark plug injectors. The helical fan includes a cylindrical body having a second central axis; a second elongated hollow shaft extending co-axially along the central axis and in gaseous communication with the first elongated hollow shaft; and a plurality of blades extending from an inner wall of the cylindrical body to an outer surface of the elongated hollow shaft.

The present invention discloses a wind power generation tower. The wind power generation tower, according to one embodiment of the present invention, can implement wind power generation by accelerating wind speed even for low speed wind and simultaneously increasing the utilization efficiency of the wind which rotates blades, thereby improving overall power generation efficiency. In addition, the wind power generation tower, according to the one embodiment of the present invention, can increase the intensity of the wind by a Venturi effect and simultaneously increase the drop in pressure of the wind escaping the wind power generation tower by using the vortex generated at the rear surface of the wind power generation tower in a cylindrical shape, thereby improving the rotation of the blades provided to the inside of the wind power generation tower so as to enable faster rotation of the blades.

This presents a Utility Model related to an improvement introduced in a piece of equipment conceived to capture wind power generated by the displacement of trains, subways, vehicles in generaloverall trucksalong railroads, roads, etc., and to convert it in electrical power, thus using such considerable energetic potential. Considering that the assembly of one or a plurality of wind rotors (P) and respective electricity generators (G) are assembled on semi-tows (K) of the type engaged and handled by a truck (mechanical horse), considering that the trailers (K) provided with means for storing the electrical power generated, such as batteries (B), or other means for electricity transmission and storage. Thus, the aerogenerators (P) may be displaced to the points with the biggest flow of passing vehicles, and may also be positioned on the direction where the natural (predominant) winds are favorable to the best use of the wind potential.

Wind driven apparatus is provided including upright support means and a plurality of wind directing wall members protruding outwardly from the upright support means at spaced apart intervals. The area between two adjacent wind directing wall members creates a wind collection section for collecting and directing wind in use. At least one opening is defined in the upright support means in each wind collection section for allowing wind, air and/or air pressure collected in the wind collection section to pass through said at least one opening and into an inner compartment defined in the upright support means. Drive shaft means provided in the inner compartment of the upright support means and rotatable means provided on and/or associated with the drive shaft means are rotatable as a result of air pressure and/or air flowing into the inner compartment via said at least one opening. Rotation of the drive shaft means can be used to drive electricity generating means, hydraulic pump means and/or drive transmission means in use.

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 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.

A wind turbine assembly include a housing, a turbine disposed in the housing and configured to rotate about an axis, the turbine including a rotor and a plurality of blades which protrude from an outer surface of the rotor, and a funnel configured to collect fluid stream energy through a fluid inlet opening and to direct at least a portion of the collected fluid stream energy into the housing and in a first direction toward the turbine, and the funnel and the housing are configured to rotate together about an axis independently of the turbine blades.

A compact self contained Engine using wind power to generate electricity. Each engine is able to operate 2 generators simultaneously. It is possible to install multiple units of the engine for large scale commercial use.

A system for harnessing wind energy to charge the electric storage battery of a vehicle, whether the vehicle is parked or in motion. While the vehicle is being driven, a roof-mounted, internal wind turbine harnesses wind energy and causes rotation of the shaft of an electric generator mounted to an interior surface of the roof. For charging the battery while the vehicle is parked, an external wind turbine is storable in the vehicle when not in use and attaches to the internal wind turbine. Cups of the kind used in cup anemometers are attached to radial arms that extend from an external shaft of the external wind turbine and catch ambient wind currents while the vehicle is parked, causing the external shaft and the generator shaft to rotate.
