Abstract:
An HMSWT is disclosed which is constructed of successive cage type turbine assemblies. The multiple turbine assemblies are preferably induced into a reverse rotational movement from one another in a coupling effect. A first turbine assembly is propelled and forced into a rotational movement propelled by the oncoming wind which in turn induces a second, inner turbine assembly to rotate in an opposite and reverse direction. This coupling effect enables the rotational movement of two or more turbines with the same oncoming wind and airflow. The particular design of these multiple blades not only enhance the propelling force of the wind by increasing rotational movement, but simultaneously redirects the same airflow inward increasing the velocity of the airflow and propelling it onto the inner turbine assembly.

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    The present application claims priority to and incorporates herein by reference U.S. Provisional Patent Application Ser. No. 61/505,506, filed on Jul. 7, 2011. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    A windmill is a machine which converts the energy of wind into rotational energy by means of vanes called sails or blades. The windmill has been used for hundreds of years as a way to harness the earth&#39;s power and transform this mechanical movement in order to do work. Wind power has been used as long as humans have put sails into the wind. For more than two millennia wind-powered machines have ground grain and pumped water. In the course of history the windmill was adapted to many other industrial uses. An important non-milling use is to pump groundwater up with wind pumps, commonly known as wind wheels. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for live stock and steam engines. 
         [0003]    With the development of electric power, wind power found new applications in lighting buildings remote from centrally-generated power. Throughout the 20th century small wind plants suitable for farms or residences were developed, and larger utility-scale wind generators were also constructed that could be connected to electricity grids for remote use of power. Windmills used for generating electricity are commonly known as wind turbines. In modern times the wind has been harnessed to create mechanical power to produce electricity with many more alternate applications. Windmills are essentially fans in reverse; instead of using the electricity to make wind for ventilation, they use wind to create mechanical power to in turn produce electricity. 
         [0004]    Today wind powered generators operate in every size range from small units and up to near-gigawatt sized offshore wind farms that provide electricity to national electrical networks. The idea behind it is simple and time-tested. Wind turns the blades of the windmill which in turn, turns a shaft. The shaft turns a gearbox that turns a generator. The larger the windmill, the more efficient it is and the more energy it produces. These wind turbines are very useful because they work wherever there are decent levels of wind. This means that any remote weather stations, water pumping stations, remote electrical stations and farms to name a few applications, can be powered by one or a series of wind turbines. Hybrid systems have been developed as well, that use wind turbines in conjunction with diesel generators, solar cells, and battery packs in order to deliver a more consistent source of power. 
         [0005]    However, conventional wind turbines and present construction designs have serious operational limitations which hamper their performance capabilities and power output range. Some of the disadvantages are related to the operational strength of the wind which at times is not constant and varies from zero to storm force. This means that conventional wind turbines do not produce the same amount of electricity all the time. In general with most conventional HWAT or VWAT wind turbines, the head winds have to be at least 17 mph strong to make the blades spin and thus produce energy. There will be times when they produce no electricity at all. Large wind machines have to be shutdown if the wind is too strong, to avoid damage because they cannot exceed a certain rotational speed. 
         [0006]    The conventional designs and present blade construction cannot withstand excessive rotational forces such as torsion and high tension directly associated with high rotational speeds. Unfortunately, increased energy and electrical production is directly to and absolutely require high rotational speeds. The only practical way to produce large amounts of power is to use hundreds of them in an array in a place where the wind is most constant, such as floating on platforms out to sea, as is being done in various regions of the world. The enormous size and wing or blade span is also another huge disadvantage of these conventional wind turbine designs. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    An embodiment of the present invention includes a multiple stage turbine comprising: a first cylindrical turbine assembly having a plurality of blades positioned longitudinally around a circumference of the first turbine assembly; a second cylindrical turbine assembly having a plurality of blades positioned longitudinally around a circumference of the second turbine assembly, said inner second cylindrical turbine assembly extending longitudinally within the first cylindrical turbine assembly; wherein the blades of the first turbine assembly are shaped, positioned and angled to cause rotation of the first turbine assembly in a first direction when exposed to airflow, and to channel the airflow inward toward the second cylindrical turbine assembly; and where the blades of the second turbine assembly are shaped, positioned and angled to cause rotation of the second turbine assembly in a second direction which is opposite the first direction when exposed to the airflow. 
         [0008]    According to the broad aspect of an embodiment of the present invention, there is provided a Horizontal Multiple Stages Wind Turbine (“HMSWT”). One embodiment of the present invention relates to a revolutionary new concept and design which uses the wind&#39;s natural kinetic energy to create a rotational movement which is in turn transformed into mechanical energy and generation of electrical power. The HMSWT preferably incorporates a revolutionary turbine assembly blade design and construction, innovative system functionality using aeronautical principles in blade design and coupling effect as part of a multiple turbine blade assemblies within the HMSWT. 
         [0009]    However, it will be explained and understood that the transformation of this kinetic energy from the wind creating rotational movement and mechanical energy into electrical energy is achieved by means of power generating components and accessories. As a non-limiting example, such accessories and components may include: multiple turbine assemblies connected to independent shafts which are in turn connected to permanent magnetic alternators or generators which create three phase AC or alternative current power. This electrical power may then be rectified to DC or direct current in order to charge large power storage batteries or feed a grid-synchronous inverter. 
         [0010]    An enormous advantage of the HMSWT is its turbine blade design and the multiple turbine assemblies which are preferably induced into a reverse rotational movement from one another in a coupling effect. To better explain the operational capability and advantages of this new innovative system one must understand the relationship and interaction between the multiple turbine assemblies. An outer turbine assembly is propelled and forced into a rotational movement propelled by the oncoming wind which in turn induces the second and inner turbine assembly to rotate in an opposite and reverse direction. This effect—called the coupling effect—enables the rotational movement of two or more turbines with the same oncoming wind and airflow. This effect is created by the multiple blades constructed within each of the turbine assemblies. The particular design of these multiple blades not only enhance the propelling force of the wind by increasing rotational movement but simultaneously these blades redirect the same airflow inward increasing the velocity of the airflow and propelling it onto the inner turbine assembly. 
         [0011]    The multiple blades of the inner turbine assembly are preferably positioned in reverse configuration from the outer turbine assembly as discussed below, allowing them to receive this high velocity airflow which then induces and forces a reverse and opposite rotational movement. Subsequently, a turbine assembly rotates in a reverse rotational direction from a turbine assembly positioned immediately to its inside or outside. This process can be repeated in the case where more than two turbine assemblies are constructed within the HMSWT. 
         [0012]    In the preferred embodiment, the HMSWT will be constructed with two turbine assemblies: a primary outer turbine assembly and a secondary inner turbine assembly. In an alternate embodiment, the HMSWT may be comprised of a multiple of turbine assemblies such as three or more. The HMSWT can be constructed in various sizes which directly affect output range and electrical power production. Thus, the overall size of the HMSWT may and will vary also according to the number and size of the turbine assemblies. 
         [0013]    This innovative new design and advanced operational concept enables for increased rotational speeds which directly increases the electrical power production capabilities. The advanced blade design construction of each of the multiple blade turbine assemblies are designed to accentuate rotational movement while simultaneously siphoning and propelling the oncoming airflow at a higher velocity inward. Each turbine assembly is constructed in a reverse configuration from the previous and/or subsequent turbine assembly. Therefore, it must be understood that the rotational movement of one turbine assembly induces the reverse rotational movement of the other turbine assembly and so on. 
         [0014]    This entirely new technological and innovative concept provides for increased strength and sturdiness, more compact design and construction while simultaneously achieving increased rotational speeds which directly translates into greater production capabilities of electrical energy. This new design incorporating advanced aeronautical blade construction, does not compromise on power output but rather greatly increases operational efficiency and electrical power generation through its capability of operating in adverse conditions with high head winds causing high rotational speeds. 
         [0015]    The HMSWT turbine assemblies&#39; blade design and coupling effect concept will be able to produce greater electrical power output with the same oncoming wind as compared to the conventional wind turbines and will be capable of operating in variable, strong or moderate wind conditions as well as in nonexistent wind conditions. The HMSWT operational capabilities of achieving and sustaining high rotational speeds due to its construction and the coupling effect of the multiple outer and inner turbines enable this new wind turbine concept to produce greater electrical power generation and output. The design innovation may also include and utilize reverse magnetic propulsion to provide a minimum rotational movement in order to enable electrical power production even in the absence of wind.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0030]    The present invention relates to a Horizontal Rotational design of Multiple 
         [0031]    Stages Wind Turbine (“HMSWT”). This revolutionary concept and design uses the wind&#39;s natural kinetic energy to create a rotational movement which is in turn transformed into mechanical energy and generation of electrical power. It will be explained and understood that the transformation of this kinetic energy from the wind creating rotational movement and mechanical energy into electrical energy is achieved by means of power generating components and accessories such as: multiple turbine assemblies connected to independent shafts which are in turn connected to permanent magnetic alternators which create three phase AC power. This electrical power is then preferably rectified to DC or direct current in order to charge large power storage batteries or feed a grid-synchronous inverter. 
         [0032]    In a preferred embodiment, the turbine blade assemblies may be connected directly to one or several alternators via one or multiple shafts which eliminate the use of gearboxes. However, in an alternate embodiment, the HMSWT design may incorporate multiple gearboxes, one for every turbine assembly, in order to increase the alternator&#39;s speed in the case where the turbine assemblies are rotating slower. 
         [0033]    As shown in  FIGS. 1A ,  2  and  3 , in a preferred embodiment, the HMSWT  1  incorporates two turbine assemblies: a primary outer turbine assembly  2  and a secondary inner turbine assembly  4 . Primary turbine assembly  2  includes outer blades  6 , while secondary turbine assembly  4  includes inner blades  8 . However, in an alternate embodiment as shown in  FIG. 1B , an HMSWT la may incorporate a tertiary mid turbine assembly  10  having mid blades  12 . For ease of reference, HMSWT  1  with only two turbine assemblies  2 ,  4  will be discussed hereinafter unless otherwise noted. 
         [0034]    As can be seen in  FIG. 1A , HMSWT  1  includes a ceiling  14 , a base  18  and a rotational housing  20 . In operation, wind enters the outer turbine assembly  2 , causing it to spin. The blades  6  of outer turbine assembly  2  channel the wind into the inner turbine assembly  4 , causing it to spin in the opposite direction of outer turbine assembly  2 . In HMSWT  1   a  of  FIG. 1B , the outer turbine assembly  2  channels the wind to mid turbine assembly  10 , causing the mid turbine assembly  10  to rotate in a direction opposite the outer turbine assembly  2 . The blades  12  of the mid turbine assembly  10  channel the wind to the inner turbine assembly  4 , causing the inner turbine assembly  4  to rotate in a direction opposite the mid turbine assembly  10 . Thus, in HMSWT  1   a , the outer turbine assembly  2  and the inner turbine assembly  4  rotate in the same direction, which is opposite the direction of rotation of the mid turbine assembly  10 . 
         [0035]      FIG. 2  illustrates a cross-sectional view of HMSWT  1 , illustrating the relationship between outer turbine assembly  2  and inner turbine assembly  4 . Preferably, the inner turbine assembly  4  is connected to an inner shaft  22 , while the outer turbine assembly  2  is connected to an outer shaft  24 . Outer shaft  24  is preferably hollow, such that inner shaft  22  can rotate independently therein. Inclusion of a mid turbine assembly  10  would preferably also include a third, hollow mid shaft (not shown) which rotates independently of shafts  22 ,  24 . Inner shaft  22  may also be hollow. 
         [0036]    The outer shaft  24  preferably resides within rotational housing  20 , and preferably extends down to and sits within lower coupling  26  located in base  18 . The inner shaft  22  preferably extends through the hollow portion of outer shaft  24 , and extends upward from the base  18  to the top of the HMSWT  1  where it inserts and joins into a top coupling  16 . This top coupling  16  is then fitted into a ceiling coupling  17  located in the ceiling  14  of HMSWT  1 . This ceiling coupling  17  is preferably wider in diameter than the top coupling  16 . 
         [0037]    In one embodiment, top coupling is  16  is constructed with internal roller bearings located within the sidewalls of top coupling  17  so as to allow the inner shaft  22  to rotate about its longitudinal axis therein, and provide for a tight fit and low spacing tolerance between the inner shaft  22  and the roller bearings within the top coupling  16 . This construction allows for stability during rotational operation without permitting material vibrations. Subsequently, the tightly fitted top coupling  16  is inserted into the wider ceiling coupling  17 , which provides for lateral stability and sturdiness not only for the inner turbine assembly  4  but also the outer turbine assembly  2  and the entire HMSWT  1  structure. Additionally or in the alternative, ceiling coupling  17  may include roller bearings in its side wall. 
         [0038]    Once the HMSWT 1  is assembled and parts are fitted into each other this amalgamation of all the components provides total structural strength. The HMSWT  1  concept is therefore more sturdy and reliable due to its design which can withstand greater frontal and operational forces imposed by high incoming winds such as; torsion, stress, and strain. This design can withstand much greater airflow pressures and thus achieve substantially higher operational capabilities as compared to standard HAWT horizontal or VAWT vertical air wind turbines. Consequently, the HMSWT  1  concept can achieve a higher rotational speed which directly affects and increases electrical output and consequently increasing power production. In another alternate embodiment, the outer turbine assembly  2  and inner turbine assembly  4  are separately mounted. 
         [0039]    In a preferred embodiment, in addition to wind providing the rotational movement of the HMSWT  1 , there may also incorporate magnetic assemblies located in or proximate ceiling  14  (not shown) and/or base  18  (as shown in  FIG. 3 ). Industrial magnets  28  may be installed in a reverse polarity configuration to assist in the rotation of the turbine assemblies  2 ,  4  even in the absence of or presence of weak oncoming winds. Corresponding magnetic modules  29  are also preferably mounted to the upper (not shown) and/or the lower portion of the turbine assemblies  2 ,  4  or the housing therearound. A combination of both wind and reverse magnetism can thereby create a continuous propelling force and motion which constantly rotates the HMSWT  1 . 
         [0040]    During operation, the magnetic modules  28 ,  29  installed both in base  18  and on the rotating turbine assemblies  2 ,  4  are in close proximity to one another and are of inversed polarity creating a strong repulsion resulting in a rotational force. The design and positioning of these magnetic modules  28 ,  29  will direct the rotational movement of the turbine assemblies  2 ,  4  that are being propelled clockwise and counterclockwise according to the blade configuration of the particular turbine assembly  2 ,  4 . 
         [0041]    Each of these turbine assemblies  2 ,  4  and  10  may be independently connected to separate magnetic generators by means of rotating shafts and gear assemblies, producing varied intensities of power output according to their rotational speed and cycles. Due to the installation of these magnetic leads located on the rotating turbine assemblies and the fixed HMSWT  1  structure housing, the rotational movement creates electricity as they come in close proximity. The magnetic polarity created by the rotors on the rotating turbine assemblies  2 ,  4  and  10  and stators part of the magnetic generators located in the base  18  produce electrical energy and power. 
         [0042]    In one embodiment, the outer turbine assembly  2  is supported on and rotates around upper and lower track and bearing assemblies  30 ,  32 . These track and bearings assemblies  30 ,  32  allow for lateral stability without limiting rotational movement and speed. The track and bearings assemblies are structured as would be understood by one of ordinary skill in the art, and preferably include bearings mounted around a track (not shown). Whereas shaft  22  allows the inner turbine assembly  4  to rotate, the track and bearing assemblies  30 ,  32  allow the outer turbine assembly  2  to freely rotate. In an alternative embodiment, both or all of the turbine assemblies  2 ,  4  may be mounted on track and bearing  30 ,  32 . In another alternative, one or more of the turbine assemblies  2 ,  4 ,  10  may sit on a magnetic air cushion created by magnetic modules  28 ,  29 . This would provide not only the propelling force, but simultaneously the above discussed cushion of air. 
         [0043]    HMSWT  1  may incorporate blades  6 ,  8  having a variable blade pitch design. As discussed above, the design and rotational movement of the outer turbine assembly  2  draws airflow inward while simultaneously thrusting the airflow toward the inner turbine assembly  4  and increasing its velocity and pressure. This airflow then forces the reverse rotational movement of the inner turbine assembly  4 . In order to create this reverse rotation, in a preferred embodiment the blades  6 ,  8  within the turbine assemblies  2 ,  4  are fixed position blades with an accentuated important curvature. 
         [0044]    An exemplary shape and orientation of blades  6 ,  8  and  12  is shown in  FIG. 4 . As will be understood, such blades  6 ,  8  and  12  are shown in  FIG. 4  as being substantially linear with one another for ease of explanation, although as installed in turbine assemblies  2 ,  4  and  10 , such blades  6 ,  8  and  12  would be configured in concentric rings. The shape and orientation of these blades  6 ,  8  and  12  not only creates rotational movement but also thrusts airflow  40  inward toward subsequent turbine assemblies to cause the reverse rotation thereof. The turbine assemblies&#39;  2 ,  4 ,  10  multiple blade design generates a strong rotational movement while at the same time creating a funneling effect moving the airflow inward increasing its velocity and pressure. The blade  6 ,  8  and  12  and camber design of these turbine assemblies  2 ,  4  and  10  is such that upon receiving the incoming airflow  40 , this airflow  40  is then guided, siphoned and redirected inwardly while simultaneously increasing the velocity and pressure of airflow  40 . This airflow  40  then travels inward coming in contact with the blades  8  of the inner turbine assembly  4  or, in the alternate embodiment, a mid turbine assembly  10 , creating opposite rotational thrust and movement thereof. 
         [0045]    As shown in  FIGS. 5B and 5C , in one embodiment, the blades  6 ,  8  and  12  may be designed with a variable leading edge slat  46 a or slot winglet  46   b , and/or a trailing edge winglet  44 . Such slats  46   a , slots  46   b  and winglets  44  improve the laminar flow and direction of the airstream across the blades  6 ,  8  and  12  in order to reduce turbulence, vibration and drag  40   a , especially at high rotational speeds, resulting in greater rotational thrust capabilities of each turbine assembly  2 ,  4  and  10  which translates in increased power generation. 
         [0046]    Therefore, in an embodiment including at least three turbine assemblies, the design and orientation of blades  6  cause airflow  40  to be propelled at a high pressure inward by the outer turbine assembly  2  spinning in a direction, inducing and forcing the mid turbine assembly  10  to rotate in an opposite direction. In turn, the mid turbine assembly  10  then repeats this process, inducing and forcing the airflow  40  into the inner turbine assembly  4  and causing it to rotate in a direction opposite the mid turbine assembly  10  and the same as the outer turbine assembly  2 . This induced rotational process and reversed coupling effect allows for these multiple stages of turbine assemblies to operate simultaneously but in opposite rotational direction from any subsequent and preceding turbine assemblies, generating tremendous force and pressure which translates into motion which can then be harnessed and transformed into energy and electrical power. 
         [0047]    In a preferred embodiment, the blades  6 ,  8  and  12  and turbine assemblies  2 ,  4  and  10  may be constructed of aluminum, titanium, carbon fibers, or any combination of alloys and materials which best provide high tensile strength, durability, light weight and resistance to the elements. This increases performance capabilities according to the operational environment in which the HMSWT  1  would be installed. The construction materials used for the blades  6 ,  8  and  12  and the turbine assemblies  2 ,  4  and  10  are preferably be capable of handling sustained high incoming airflow pressures and accommodate increased rotational speeds. As will be understood, construction specifications and materials which will be used will be dependent on the operational as well as on site environmental conditions in which the HMSWT  1  will be exposed to and functioning in. In a preferred embodiment, the metal of choice used in the construction of the turbine blades  6 ,  8  and  12  and assemblies  2 ,  4  and  10  is aluminum alloy and/or composite materials and/or wood in order to provide sturdiness and lightweight construction. The number of blades  6 ,  8  and  12  within the turbine assemblies  2 ,  4  and  10 , their size, thickness, camber and depth may vary according to the diameter, size and power output range and specific operational design requirements of the HMSWT  1 . 
         [0048]    The environmental conditions and operational location in which the HMSWT  1  will be adapted to and functioning in will also determine the design parameters and unit specifications. In a preferred embodiment, the blade and camber design of the multiple turbine assemblies will resemble an aeronautical wing design having a streamlined yet accentuate curvature of the upper and lower camber as well as the thickness of the wing, as seen in  FIG. 6B , in order to enhance and accelerate the airflow movement rearward. Preferably, a blade is rounded at its leading edge and widens to have a camber thickness which is larger near the front of the blade and narrows down to a relatively sharp trailing edge, as shown in  FIG. 6B . Generally, a blade preferably has an upper camber which is greater in thickness than its lower camber. 
         [0049]    As seen in  FIG. 6A , each turbine assembly  2 ,  4  and  10  may include pivoting rings  56  and  58  located horizontally at either or both of the top and bottom of the turbine assembly. Leading and/or trailing edges of the blades  6 ,  8  or  12  may be connected to the pivoting rings  56  and  58  at points  52  and  54 , respectively. Additionally or in the alternative, blades  6 ,  8  or  12  may each be connected to pivoting bearing assembly  48 ,  50 . The pivoting rings  56 ,  58  and/or the pivoting bearing assemblies  48 ,  50  may be used to pivot the blades  6 ,  8  and  12  and adjust their pitch. The pivoting rings  56 ,  58  and/or the pivoting bearing assemblies  48 ,  50  may link blades  6  or  8  or  12  together for simultaneous adjustment of blade pitch in each respective turbine assembly  2 ,  4  and  10  separately from the other turbine assemblies  2 ,  4  and  10 . A motor (not shown) as would be understood in the art may be utilized to rotate the blades  6 ,  8  and  12 . 
         [0050]    The blade design will also promote and maintain linear airflow to avoid turbulence and restriction in efficiency. The design of both the upper and lower camber sections of the blade design (seen in  FIG. 6B ) as well as the positioning of the blades within the same turbine assembly in relation to one another will compress and concentrate the airflow as it moves rearward creating higher velocity and static pressure. 
         [0051]    In an alternative embodiment as seen in  FIG. 7 , a turbine assembly may have similarities to an impeller. An impeller design receives the airflow and then inducing this airflow by creating a vacuum that siphons this airflow and increasing both its velocity and pressure. In this alternate embodiment, the design of the thickness, and upper and lower camber width of blades  60  may be diminished and highly streamlined making it much thinner in construction. In this design configuration, the positioning of the blades  60  in relation to each other within the turbine assembly is such that airflow is received and velocity is increased as it travels rearward. 
         [0052]    Although the foregoing description and accompanying drawings relate to specific preferred and alternate embodiments of the present invention and specific methods of wind power generation and regeneration as well as various wing configurations and design systems as presently contemplated by the inventor, it will be understood that various modifications, changes and adaptations, may be made without departing in any way from the spirit of the invention.
