CROSS-REFERENCE TO RELATED APPLICATIONS
The present application is a continuation-in-part (CIP) of U.S. patent application Ser. No. 13/927,324, filed on Jun. 26, 2013, which in turn is a CIP of U.S. patent application Ser. No. 13/222,629, filed on Aug. 31, 2011. All of the above applications are herein fully incorporated by reference for all purposes.


TECHNICAL FIELD
Generally, the present disclosure relates to renewable energy. More particularly, the present disclosure relates to vertical axis wind turbines.
BACKGROUND
In the present disclosure, where a document, an act and/or an item of knowledge is referred to and/or discussed, whether directly and/or indirectly, then this reference and/or discussion is not an admission that the document, the act and/or the item of knowledge and/or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge and/or otherwise constitutes prior art under the applicable statutory provisions and/or is known to be relevant to an attempt to solve any problem with which the present disclosure is concerned.
Identification of new non-fossil fuel based energy sources, which are both commercially viable and/or environmentally benign, has become an important national security and/or technological need. With increasing domestic energy consumption, such technological development not only enhances national security, reduces visual pollution, fuels economic growth, creates jobs and/or contributes to global environmental sustainability, but also reduces foreign energy dependence.
Many countries and/or businesses often commit to make better use of renewable and/or nonpolluting energy sources. Wind energy is a popular source explored by many not just because wind energy is renewable and/or nonpolluting, but also because wind energy is free. Although wind farms with acres of large wind turbines have proved relatively successful, such wind farms are relatively rare and/or generally involve substantial economic investment, visual pollution and/or contentious land use issues. A broader, simpler, more visually appealing and/or geographically universal wind turbine construction and/or management approach may be required to bring wind energy to its full potential.
Also, in United States, utility poles are ubiquitous and/or often include power transmission capabilities. In fact, miles of open roads, spreading through wide-open spaces, are lined with a seemingly endless amount of utility poles. A significant amount of wind energy, which often encounters these poles, remains underutilized. Thus, by better utilizing already existing utility poles for wind energy generation, increasing domestic energy consumption can be more effectively managed without substantial economic investment.
Additionally, some electric utility companies, such as electric distribution cooperatives, do not generate electric power. Rather, these companies purchase electricity from another entity. Thus, these companies are caught in the middle of a vibrant energy supply and/or demand market and, generally, do not have control over rising energy costs. Similarly, these companies also often face arbitrary political mandates and/or unreasonable customer demands for prompt provision of renewable energy without having any control over how to provide such energy.
Accordingly, there may be a need to more efficiently create and distribute renewable energy, decrease dependency on centralized electric energy generation, lessen fossil fuel use in electricity generation, minimize foreign energy dependence, reduce the price of electricity, create a new renewable energy business model, while implementing a job creating solution using an already existing infrastructure.
While certain aspects of conventional technologies have been discussed to facilitate the present disclosure, no technical aspects are disclaimed. The claims may encompass one and/or more of the conventional technical aspects discussed herein.

FIG. 1A illustrates an example mode of operation of a vertical axis wind turbine according to the present disclosure. Any element of a vertical axis wind turbine 100 can include metal, plastic or a lightweight composite material and be rustproof. Vertical axis wind turbine 100 includes a plurality of support arms 21, 22, a housing 23, a generator and a plurality of blades 26.
Arms 21, 22 are coupled to each other via a coupling rod 29. Coupling rod 29 is coupled via a bent rod 16 to a utility pole 10 above a plurality of power lines 11, which are resting on a horizontal cross-arm 12 via an insulator 13. Cross-arm 12 is supported by a support arm 25. In another example embodiment, arms 21, 22 are individually coupled to utility pole 10. In yet another example embodiment, arms 21, 22 are coupled in a V-shape, an L-shape, or an A-shape to utility pole 10. In yet still another example embodiment, arms 21, 22 are operative for coupling to a cell site, an antenna, a house roof, a transmission tower, a water tower, a lamppost, or a sign pole. In yet additional example embodiment, arms 21, 22 can form and/or be included in a bracket.
Housing 23 is coupled to arms 21, 22 via a plurality of caps 32, 33 and a plurality of shafts 24, 30, which vertically extend through arms 21, 22. Housing 23 rotates on a vertical axis of rotation and with respect to arms 21, 22.
Housing 23 also includes an outer wall defining a space within housing 23. The space is interior space and can be sealed to be waterproof and/or airtight. Although housing 23 is shown in a cylindrical shape, housing 23 can be of other shapes, such a sphere, a cube, a cuboid, a prism, a cone, a pyramid, and so forth.
A generator is stationed within the interior space. The generator generates an electric current in response to at least partial rotation of housing 23 and/or blades 26. The electric current can include an alternating current (AC). However, in another example embodiment, the electric current can include a direct current (DC). Regardless, the generator is coupled to a distribution transformer 14 via a wire 18, which conducts the generated electric current. The generator can include a generator shaft. Distribution transformer 14 is coupled to utility pole 10 via a plurality of bands 17, which also couple a bent rod 16. Bands 17 are adjustable via a plurality of adjusters 19.
Blades 26 are coupled to an external surface of the outer wall of housing 23. Blades 26 extend in a vertical direction, parallel to the external surface of housing 23. Blades 26 are coupled to the external surface of housing 23 via a connector and a band extending around the outer wall of housing 23. In another example embodiment, the band can rotate with respect to the generator and/or housing 23.
Caps 32, 33 are coupled to opposing sides/bases of housing 23. Caps 32, 33 can be stationary with respect to housing 23. Although a portion of caps 32, 33 is hemispherical, such as dome shaped, in general, caps 32, 33 can be flat and/or rectangular and/or any other shape, such as a circle, a triangle and so forth. Each cap 32, 33 includes a bearing. Housing 23 rotates around the bearings. Cap 33 includes an opening for wire 18, which connects to power lines 11 via distribution transformer 14, a coil 20 and a plurality of connecting wires 15. The opening for wire 18 can include a grommet. Cap 32 is coupled to arm 21 via shaft 24 extending into a portion of cap 32. Cap 33 is coupled to arm 22 via shaft 30 extending into a portion of cap 33.
In another example embodiment, vertical wind turbine 100 can include a heater to generate a small amount of heat near bearings. For example, such generated heat can be used to keep the bearings from freezing. Such heater can be self-powered, such as via a battery, or powered via the generated current from turbine 100.
FIG. 1B illustrates another example mode of operation of a vertical axis wind turbine according to the present disclosure. Some elements of this figure are described above. Thus, same and/or similar reference characters identify same, and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Note that the opening for wire 18 is depicted via opening 27, which can include a grommet. Also, note that the connector for blade 26 is depicted via a connector 31, such as a bridge, like a bar, a shaft, and others. Resultantly, blades 26 are coupled to the external surface of housing 23 via connector 31 and the band extending around the outer wall of housing 23.
A difference between FIGS. 1A and 1B is a placement of vertical axis wind turbine 100. In FIG. 1B, coupling rod 29 is coupled via bent rod 16 to utility pole 10 below power lines 11. Thus, vertical axis wind turbine is positioned below power lines 11.
In another example mode of operation, on utility pole 10, at least one vertical axis wind turbine 100 is positioned below power lines 11 and at least one vertical axis wind turbine 100 is positioned above power lines 11. For example, two opposing vertical axis wind turbines 100 can be positioned below power lines 11 and two opposing vertical axis wind turbines 100 can be positioned above power lines 11. For another example, a plurality of adjacent vertical axis wind turbines 100 can be positioned below/above power lines 11 on one side of utility pole 10 and plurality of adjacent vertical axis wind turbines 100 can be positioned below/above power lines 11 on opposing vertically extending side of utility pole 10. For yet another example, a plurality of vertical axis wind turbines 100 can be positioned on one side only. Note that any number of turbines 100 can be coupled to pole 10 in any combinatory manner.
FIGS. 2A and 2B illustrate a top view of an example embodiment of a vertical axis wind turbine in operation according to the present disclosure. Some elements of this figure are described above. Thus, same and/or similar reference characters identify same, and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Vertical axis wind turbine 100 is coupled to utility pole 10 via cap 32, shaft 24 and arm 21. Vertical axis wind turbine 100 rotates on a vertical axis in a direction D. As vertical axis wind turbine 100 rotates, an electric current is generated by the generator stationed within housing 23. Note that blades 26 are below are 21.
FIG. 3 illustrates an internal perspective view of an example embodiment of a vertical axis wind turbine according to the present disclosure. Some elements of this figure are described above. Thus, same and/or similar reference characters identify same, and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Note that the band around housing 23 is depicted as a band 28, which can extend horizontally and/or diagonally in any manner. A central shaft 316 can extend from an external surface of cap 32 into a gear box 310. Although central shaft 316 can rotate at a low speed and include a plurality of shaft-to-shaft stabilizing bearings 311, in another example embodiment shaft 316 can also remain stationary. Central shaft 316 includes a first gear wheel mounted thereon. A generator 313 includes a generator shaft 312 with a second gearwheel mounted thereon, which can rotate at a high speed. The first gear wheel meshes with the second gear wheel in gear wheel box 310. Although central shaft 316 and generator shaft 312 are parallel to each other, in another example embodiment, shaft 316 and shaft 312 are not parallel to each other. Generator shaft 312 extends from a base 314 mounted on a surface 315 of cap 33 through generator 313 into gear box 310. Generator 313 can include a controller or at least one magnet. Thus, as housing 23 rotates, central shaft 316 rotates and thereby facilitates meshing of gear wheels within gear box 310, which in turn power generator 313 to generate an electric current for conduction via wire 18 to distribution transformer 14. Band 28 can rotate with respect to 313 generator and/or housing 23. Note that at least one of shaft 316 and shaft 213 can be stationary with at least one of the first gear wheel and the second gear wheel rotating. In another example embodiment, at least one of arms 21, 22, housing 23, caps 32, 33, connector 31, band 28, coupling rod 29, shafts 24, 30, bent rod 16 and blades 26 includes non-conductive material, such as porcelain or composite polymer materials.
FIG. 4 illustrates a side view of an example embodiment of a vertical axis wind turbine according to the present disclosure. Some elements of this figure are described above. Thus, same and/or similar reference characters identify same, and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
Cap 32 includes a bearing 420. Cap 33 includes a bearing 410. Using bearings 410, 420, housing 23 rotates on a vertical axis. In another example embodiment, bearings 410, 420 are coupled to a heater to generate a small amount of heat near bearings 410, 420 to keep bearings 410, 420 from freezing.
Housing 23 has a housing roof 23T and a housing sidewall. Housing roof 23T is coupled to the housing sidewall. Blades 26 are secured to an external surface of the housing sidewall. Housing roof 23T has a central opening 23A through which central shaft 316 extends, but central shaft 316 is also coupled to housing roof 23T via a connection hardware 317. Central shaft 316 is stabilized by a connection to cap 32 via a shaft bearing 316A.
Central shaft 316 includes a first gear wheel 430. Generator shaft 312 includes a second gear wheel 440 meshing with first gear wheel 430 at a meshing point (MP). As central shaft 316 rotates with housing 23, first gear wheel 430 meshes with second gear wheel 440 at MP and powers generator 312. Generator shaft 312 is located in an offset position from a central axis of housing 23. As previously noted, generator 312 is secured to base 314 of cap 33 with a lower bearing, which allows axial rotation of generator shaft 312. However, note that at least a portion of shaft 312 can be co-axial to shaft 316.
In another example embodiment, by incorporating vertical wind turbine 100, as described herein, on already existing infrastructure, energy produced via turbine 100 can reduce a demand for energy from a power plant thereby efficiently creating and distributing renewable energy, decrease dependency on centralized electric energy generation, lessen fossil fuel use in electricity generation, minimize foreign energy dependence, reduce the price of electricity, create a new renewable energy business model, while implementing a job creating solution using an already existing infrastructure. Moreover, turbine 100 can produce electricity incrementally without overloading the electrical grid. Furthermore, by placing turbine 100 on top of utility poles 10, whether above or below transmission lines 11, more wind power can be captured.
FIG. 5 illustrates a perspective view of an example embodiment of a vertical axis wind turbine having a top vertical axis wind turbine according to the present disclosure. Some elements of this figure are described above. Thus, same and/or similar reference characters identify same, and/or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.
A wind turbine 200 is coupled to arms 21, 22 via shafts 24, 30, which extend through arms 21, 22. Shafts 24, 30 can rotate, and/or be fixed with respect to arms 21, 22. Housing 23 includes a top vertical axis wind turbine 32, which replaces cap 32 as shown in FIGS. 1A-4. Turbine 32 includes a base 32.1 and a plurality of foils 32.2 having a plurality of open spaces 32.3 in-between. Note that wire 18 can extend via shaft 24. Note that turbine 32 can be coaxial with cap 33 or have different axis with respect to cap 33. Turbine 100 and turbine 200 can be co-axial.
Base 32.1 can be of any shape, such as a parallelogram, a quadrilateral, an ellipse, a triangle, a polygon, a character, a symbol, and/or others in at least one dimension. Base 32.1 includes a plurality of magnetic transformers disposed around outer perimeter of base 32.1.
Shaft 24 can be coupled to base 32.1. Shaft 24 can also remain de-coupled with base 32.1. Shaft 24 can also avoid contact with base 32.1. Shaft 24 can extend through base 32.1. Shaft 24 can also be coupled to shaft 316 for dependent wind capture. However, shaft 24 can also be de-coupled from shaft 316 for independent wind capture. Shaft 24 can be segmented. Shaft 24 can include a rotor mounted thereon, which can include a plurality of magnets disposed around outer perimeter of the rotor.
Base 32.1 can include a first magnet having a first polarity. The rotor can include a second magnet having a second polarity. The first magnet and the second magnet are positioned such that the first magnet and the second magnet are adjacent when axially aligned. The first polarity and the second polarity are such that the first magnet and the second magnet repel each other at least when installed as described herein and thereby enable levitation, such as floating and/or suspension, of the rotor above base 32.1. In any combinatory manner, the magnets can be identical to and/or different from each other in number, material, shape, size and/or any dimension, such as length, width, height, depth, area, volume, breadth, density, temperature, resistance and so forth.
Foils 32.2 extend spirally/helically about shaft 24 with spaces 32.3 in-between, while coupled to shaft 24. Foils 32.2 can extend in a rotating manner such that turbine 32 appears like an auger. Note that turbine 32 faces skyward, whether vertically or diagonally. In any combinatory manner, foils 32.2 can be identical to and/or different from each other in number, material, shape, size and/or any dimension, such as length, width, height, depth, area, volume, breadth, density, temperature, resistance and so forth. Foils 32.2 can be curved. Foils 32.2 are shaped to maximize wind energy capture irrespective of wind source, speed and/or direction. Foils 32.2 can be triangular of any type. Foils 32.2 can be linear, curvilinear and/or others. Foils 32.2 can be equally spaced apart and/or non-equally spaced apart in any manner.
The first magnet and the second magnet provide that the rotor and foils 32.2 levitate magnetically off base 32.1. Such levitation reduces friction and enhances ease of rotation, which can allow for avoiding inclusion of at least one bearing. Turbine 32 can include an axial flux alternator using variable resistance coils, which can be individually and/or selectively turned on or off depending on wind conditions and electrical draw requirements. The coils can also be used to selectively produce mechanical drag for foil braking in high wind conditions and/or for maintenance. The alternator enables efficient energy generation at low rotational speed. The magnets can be shielded from external exposure, such as weather and/or animals. The first magnet and the second magnet can be segmented. Alternatively, the first magnet refers to a plurality of first magnets and the second magnet refers to a plurality of second magnets.
Foils 32.2 can include magnets positioned at their tips. Foils 32.2 are magnetically levitated, such as via floating, above base 32.1, which can reduce friction, noise, vibration, energy loss and/or facilitate in more efficient energy generation. Alternatively, foils 32.2 are coupled to base 32.1, but base 32.1 magnetically levitates above another base.
The alternator includes the magnetic transformers and at least one of the magnets. In any combinatory manner, the magnetic transformers can be identical to and/or different from each other in number, material, shape, size and/or any dimension, such as length, width, height, depth, area, volume, breadth, density, temperature, resistance and so forth. The magnetic transformers can include a cored coil and/or a coreless coil. The magnets can be passive magnets.
