Electric and hydrogen technology automobiles and vehicles such as trucks, buses, ships and boats are believed to be the future of transportation; however for the time being, the problems surrounding the technologies are significant and have kept the consumers away for various reasons including the capacity of batteries and fuel cells, the lack of filling stations, and most of all the limited distance the vehicles can travel without a recharge, which for small electric vehicles can take up to 20 minutes before they can continue to travel with a full battery or fuel cell. Commercial vehicles in particular; cannot take the time to stop frequently and worst yet take the significant amount of time that it would take to recharge their systems. Hybrid vehicles still rely on gasoline which is available to increase the travel distance, but customers concerned for the environment have not yet embraced the solution and larger vehicles such as commercial trucks are not about to take the risk of being left out without fuel under any circumstances. This current invention “Airflow Power Generating Apparatus’ is for use in present and future electric and hydrogen technology vehicles and solves the challenges present today as it provides a system to charge batteries and fuel cells while the vehicle is moving forward. This system will extend the distance vehicles can travel or may eliminate completely the need to recharge batteries of fuel cells at homes or at charge stations.

This system includes a belt drive system for a wind turbine generator comprising: a tower having a wind turbine wheel rotatably attached to the tower; a generator platform attached to the tower; a generator supported by the generator platform; and, a turbine drive belt adapted to engaged with the wind turbine wheel and the generator to transfer rotational energy from the wind turbine wheel to the generator to generate electricity.

The present invention, a multi-axial variable height wind turbine, includes a wind turbine, a structural support, a tilting boom extending between said structural support and said wind turbine, a multiaxial drive mechanism extending upwardly from said structural support for receiving said tilting boom where the multiaxial drive mechanism operationally connects the tilting boom to the structural support for rotation along a plurality of axes.

The wind turbine also includes a plurality of pitched blade members extending between an inner hub and an outer ring.

A rotor blade of a rotor of a wind turbine, and to an associated wind turbine, and to a method for optimizing a wind turbine. Prior to being mounted on the wind turbine, the rotor blade is split at a parting point into an inner blade section and an outer blade section, wherein a longitudinal direction of the rotor blade is defined from the root section to the blade tip, wherein the rotor blade has at least one swirl element, wherein the swirl element has an extent in the longitudinal direction of the rotor blade, wherein a distance between a start, facing toward the root section, and an end, facing toward the rotor blade tip, of the swirl element in the longitudinal direction is referred to as total length, and wherein a distance between the parting point and the outer end of the swirl element is referred to as outer length, wherein a ratio of outer length to total length is less than 0.25.

The invention relates to a wind turbine that includes a rotor rotating about a horizontal axis of rotation substantially parallel to the direction of the wind, the rotor having a front face facing into the wind and substantially perpendicular to the axis of the wind, and a rear face situated toward a support of the rotor. At least two distinct families of blades are distributed on the rotor, each family of blades including at least two blades having a free end and a blade root end connected to said rotor. Each family of blades includes a catching blade guiding the wind toward a force blade having a surface arranged substantially perpendicular to the axis of the wind, the blade root ends of each family of blades are successively offset on an exterior surface of the rotor along the axis of rotation thereof.

A method of forming a wind turbine blade is provided which includes upper and lower blade mold halves, and a shear web having at least one aperture formed therein. A plurality of bulkheads are attached to the shear web and the shear web can be lifted and rotated, without need for a complex gantry/galactica apparatus, to be placed inside the lower blade mold. The upper mold half can then be closed with the shear web and bulkhead(s) disposed within the blade interior. A heating fluid can be pumped into the interior to pass through the bulkheads, circulating around the shear web and exiting the blade root with the assistance of a sump to pull the cold air outside the blade.

A wind driven electric generator including a rotor which intercepts air movement to turn a drive line including a first right angle drive swivelly coupled on the top of a support tower and a second right angle drive located proximate ground level to deliver rotational energy of a drive line to an electric generator located proximate ground level.

A power generating windmill having a plurality of blade extending radially outward from a central rotor in position to be engaged by a moving fluid stream is provided. Each blade partially overlaps the blade prior to and behind it to increase lift forces on the blades.

An apparatus for removing and installing a blade for a wind turbine is provided, comprising a first set of cable guides mounted within the nacelle, and a second set of cable guides positioned on an exterior surface of the rotor hub. An upper pulley block is suspended from a first hub flange and a second hub flange, wherein the upper pulley block is positioned above a third hub flange in a position for accepting the blade. A winch is positioned at a ground level, and the winch contains a lifting cable guided by the cable guides, and then reeved through the upper pulley block and a lower pulley block on a blade holding bracket, allowing the lower pulley block to be raised and lowered relative to the upper pulley block. The blade holding bracket attaches to the root end of the blade, and the lower pulley block is allowed to pivot and swivel relative to the blade holding bracket.

A method for determining an arrangement position of a vortex generator on a wind turbine blade includes: determining, for a first region of a mounting range of the vortex generator in a blade spanwise direction, an arrangement position of the vortex generator to be an angular position offset by a predetermined angle toward a trailing edge of the wind turbine blade with reference to an inflow angle of wind to the wind turbine blade; and determining, for a second region closer to a blade tip, the arrangement position of the vortex generator to be a position between a separation position of a flow on a surface of the wind turbine blade under a rated wind speed condition and a transition position of the flow on the surface of the wind turbine blade under a variable speed operation condition of a wind turbine including the wind turbine blade.
