Abstract:
The CWE Concepts are designed to extract the maximum possible wind energy passing through a given square footage area of influencing machine interface at given calculated velocities, to deliver that energy to two power take off shafts for end user&#39;s useful work (electrical power generation and other requirements). A multi-bucket “S” rotor, airfoils, baffles and cowling combined, utilize one hundred percent of that moving air volume most efficiently. Our strategies are to use smaller units, yielding more power than existing designs while being installed at much lower levels, urban friendly, less visible, nearly-enclosed rotating machinery, quieter, and safer for indigenous wildlife populations. We plan to market for commercial and residential customers, in turn providing HVAC and electrical power augmentation to utility companies—a reliable and robust addition to the national power grid. Our goals—reduce dependency on foreign oil and provide a clean alternative.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    The present invention relates generally to “Green” renewable wind energy capture to be used for useful work. The California Wind Engine “S” Rotor system units are designed to enhance the capture of wind energy much more efficiently and reliably while presenting a reduced public perception of unsatisfactory sight visibility interruption both urban and rural. The invention finds application in rural Wind Farm placements, high-rise and commercial building electrical and other power augmentation installations as well as residential and ranch/farm unit installations. 
         [0002]    More particularly, the present invention relates to great potential for urban-friendly placements whereby civil urban and rural planning departments will have a much easier task in reviewing and attaining approval consideration for satisfying the general public&#39;s needs and aesthetic desires of such wind-driven applications. Current wind energy capture devices tend to garner adverse public acceptance when considering noise pollution, eye disturbance, and hazards to indigenous bird, bat and wildlife populations. 
         [0003]    Therefore, the need exists for increasing safety for wildlife, the public in general, reduced horizon interruption, reduced noise pollution and greatly reduced visible rotation components. The need exists for installations placed at much lower elevations, units that are far more capable of power generation when compared with similar-sized wind “sweep” areas of current wind energy capture designs and concepts. Pleasant public acceptance and the potential for mass production and marketing of the present invention lend credence to the concept of economies of scale while reducing the dependence on foreign oil for our nation. 
       SUMMARY OF THE INVENTION 
       [0004]    The present invention provides physical features, shapes and material considerations of the California Wind Engine elements that are within the ordinary skill of those skilled in the art and includes end-user&#39;s needs and potential geographical requirements (as in inclement weather climes). The goals include robust, reliable year-round performance of the units to be more efficient, lower visibility, quieter and safer for the wildlife population while benefiting the environment. 
         [0005]    Specific considerations of the present invention include the following elements. Best ratio of rotor diameter to rotor chassis width and an airfoil shape, length and degree of the leading edge wind ramp will be discussed. Venturi-effect design and number of degrees of rotor rotation of the downwind opening for wind pressure relief of “used wind exhaust” flow, size, length, shape and placement of the Wind Reversal Ducting System and the size, shape and leverage position of the weather vane rudders and fins. The upwind gust detection system, over-speed governor, variable air volume vanes and wind ramp dump panels as well as anti-icing systems are a part of these specific considerations. 
         [0006]    Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0027]    In  FIGS. 1 through 19 , the CWE System presents a means of maximizing the efficiency of horizontal and vertical “S” Rotor wind turbines  5  deployed for the purpose of capturing wind energy  16 ,  18 ,  19 ,  20 ,  21 ,  23 , &amp;  30  for mechanical and electrical power production. The system employs various unique ducting and cowling enclosure designs which foil and redirect relative oncoming wind flow  16 , to permit the wind rotor turbine to exhibit positive rotational wind pressure through about three hundred degrees of rotation. The used wind exhaust  23  flows out of the unit downwind of the unit chassis  5  most efficiently via a convergent/divergent Bernoulli-Venturi design set of baffles and cowling enclosures ( FIG. 1  &amp;  FIG. 2 ). The exhaust opening radius permitting relief and escape of used wind  23  is approximately 60 degrees to allow that used wind to exhaust. A single barrel horizontal rotor assembly  1  is utilized for this CWE Description. The complete ducting, cowling and related systems and structure consists of nine (9) unique Concept Elements as follows: (See  FIG. 1  &amp;  FIG. 2 ) 
         [0028]    1. Spill Plates (Splates)  15 : solid circular plates affixed at each end of the rotor assembly to prevent captured, compressed wind inside the turbine bucket voids  1  from spilling out of the sides under Load conditions. 
         [0029]    2. Wedge-shape curved Wind Ramp  11 : Airfoil designed Wind Ramp installed at the bottom half of front of the rotor Chassis  5  leading edge. 
         [0030]    3. Wind Keeper Cowling Baffle  8  located across the top of the Wind Engine Chassis  5 , curving around the rotor bucket circumference  15  downwind, toward the backside of the Chassis  15  to seal rotor bucket voids a limited number of degrees of clockwise  9  rotation past the 12:00 o&#39;clock position. 
         [0031]    4. Cowling Enclosure concept  5 : Encloses the rotor assembly with designed side enclosures, Wind Keeper Baffle  8  top enclosure and flat sheet bottom enclosure full length of the CWE main body Chassis  5 . 
         [0032]    5. Wind Reversal Ducting System (WRDS)  6  linear ducts are mounted on both sides of lower Chassis  5  externally, allowing wind to flow internally, to reverse flow into the upwind bucket voids  1  to cancel backdraft effect. 
         [0033]    6. Weather Vane System  4 ,  10 : Small Servotabs  10  hinged to fins mounted on booms extend forward to detect approaching wind direction  16 . Large Rudders  4  are hinged to vertical Fins on booms extending downwind of the main unit Chassis  5 . Upwind Gusts detected by the Servotabs  10  control the Anti-Servotabs  4 , which move the Rudders  4  to accentuate weather vaning for moving the Chassis body  5  continuously toward best wind reception  16 . 
         [0034]    7. Aircraft-style Anti-Icing  13  prevent ice formation in cold weather. 
         [0035]    8. Wind Ramp  11 ,  12  and WRDS Neutralizing system incorporated to slow the rotor rotation  9 , and with Brakes  3  to lock rotor  1  for maintenance and safety. 
         [0036]    9. Governor system (not shown in FIGURES) for controlling maximum rotor rotation  9  and protect the CWE from over speeding past structural limits. 
         [0037]    CWE final configuration regarding number of bucket blades  1  and design may be varied for best efficiency. Configuration as shown to be considered, but CWE does not specify the six bucket “S” blades as a requirement of the CWE patent Design. 
         [0038]    CWE Concept Element #1 
         [0039]    Spill Plates (Splates)  FIG. 5  and  FIG. 6   
         [0040]    Splates  15  encloses both ends of the rotor bucket assembly  1  with two solid covers  15  to prevent captured compressed wind inside the turbine bucket  1  void to spill out from the sides of the rotor  1 , thereby decreasing the effectiveness of the compression stroke. 
         [0041]    CWE Concept Element #2, Wind Ramp 
         [0042]      FIG. 5 ,  FIG. 6 . &amp;  FIG. 7   
         [0043]    A Wind Ramp  11  is placed at the leading edge of the CWE Unit Chassis which blocks Wind Energy  18  from striking the rotating Rotor Bucket Blades  1  on the lower, upwind portion of the Rotor  1  and below the Rotor Axle  2  from the 6:00 to 9:00 o&#39;clock positions.  24 (See  FIG. 6 ). That Wind Pressure is constantly diverted from the horizontal, up the wedge-shaped airfoil  11  into the rotating Rotor Turbine  1  at or above the elevation of the Rotor Axle  2 . This allows that directed Wind Energy to flow up  18  into the arriving Bucket Voids  1  to assist rotational propulsion up to the maximum Compression Stroke area from 9:00-12:00 O&#39;clock regime  24 . The lateral edges of the Wind Ramp have vertical, curved Baffle Plates  14  on both sides that rise up with the curved Wind Ramp surface  11  and as those Plates  14  rise, they also curl inward slightly. This is to assist in retaining the flow of that portion of the oncoming Captured Wind  18  so that it does not easily spill out over the lateral side of the Ramp prior to injection into the Bucket voids  1 . Configuration of the Wind Ramp  11  and Side Baffles  14  may be varied for maximum efficiency. (See  FIGS. 7 and 8 .) For explanation of the CWE operation concept, it will always be assumed that the Wind is blowing from the left to right  16  on the Drawing Pages (a few exceptions are where the CADD reverses positions for clarity). The front of the CWE is usually facing to the left of the page. The CWE concept claims that the Rotor Buckets are seen rotating in the clockwise direction  9 . Reference  FIG. 6 , the top of the Rotor is at 12:00 with hour-hand designations of a circular clock  24  to be at 3:00 o&#39;clock 90 degrees to the right, 6:00 is at the bottom and 9:00 is at the far-left clock position. Exhausted Wind  23  flows out of the 3:00 area. 
         [0044]    CWE Concept Element #3 
         [0045]    Wind Keeper Baffle ( FIG. 9  &amp;  FIG. 10 ) 
         [0046]    A Wind Keeper Baffle  8  is located across the top of the rotor with its leading edge at the 12:00 o&#39;clock position and curves down the backside of the vertical axis of the rotating rotor assembly. It is supported by the side cowling rotor enclosure portion of the CWE chassis  5  and is curvature-shaped to fit close to the rotor bucket circumference of rotation  9 . This design is to assist the end plate retention of compressed wind energy  16  sealed inside the bucket voids to an engineered design point of release to allow the used wind to exhaust downwind. That period of holding the wind flow from the 12 o&#39;clock to the 1:30 position is designed to increase the efficiency of the CWE before allowing the used wind  23  to exhaust out of the bucket void. Just prior to at the calculated point of beginning to release  8 , the keeper baffle  8  shape radius out downward and flares upward to a minor degree, to provide the top of the convergent/divergent Bernoulli-enhanced Venturi  26  exhaust portion of the CWE chassis  5 . 
         [0047]    CWE Concept Element #4 
         [0048]    Chassis Cowling # 4  ( FIG. 1  &amp;  FIG. 2 ) 
         [0049]    The underside of the CWE Chassis  5  is enclosed, extending from the leading edge of the wind ramp  11  common to the downwind end of the unit to the exhausted wind lip. The rotor  1  is enclosed on both sides from the rotor axle  2  down to the underside plate. The side cowling  5  sweeps up just aft of the axle  2  to tie into the horizontal keeper baffle assembly  8  atop the chassis  5 . Incorporated into the wind flow sheet metal is the top flare of the keeper baffle  8  and a matching sweep with the underside plate to complete the effect of a Venturi effect design downwind to an exhaust wind outlet to assist in most efficiently drawing out of the used Wind. Materials and design may be varied to achieve desired results. (See  FIG. 5 ). 
         [0050]    CWE Concept Element #5 
         [0051]    Wind Reversal Ducting Systems (WRDS) ( FIG. 11  &amp;  FIG. 12 ) 
         [0052]    Horizontal wind intake Ducts  6  are shown mounted on both sides of the outside Chassis enclosure  5 , below the Rotor axle  2 . They are open upwind to the prevailing wind flow  16 . The purpose is to capture that portion of the wind energy  20  that is flowing past, just outside of the Wind Ramp airfoil. That captured wind  20  flows inside the horizontal ducts  6 . The Duct tubes  6 , either square or rectangular in shape, conduct that captured wind  20  internally to flow along the lower horizontal longitudinal alignment of the Chassis body  5 . The Duct tubes  6  turn 90 degrees toward the centerline of the Chassis  5  behind and below the rotating Rotor  1 . Internal fixed vanes  28  assist the captured wind  20  to turn in that 90 degree configuration, a standard HVAC ducting practice. The wind  20  then vane-turns 28 another 90 degrees to complete 180 degrees of turn, a “U”-turn of direction. The wind  20  is now being forced into an upwind direction inside the confined Rotor Cowling  5  space. The contained wind  20  is then vented into the rotating Bucket  1  voids as they continue past the “clock” positions where they just completed exhausting the used wind. This is designed to eliminate any back draft suction that would affect those Buckets  1  rotating up into the clear at the 9 o&#39;clock position above the Wind Ramp lip. CWE WRDS  6  size, shape, internal vanes  28 , intake flaring design, and internal Variable Air Volume (VAV) vanes  7  may be varied for eliminating back draft suction and control of excess wind speeds. WRDS Ducts  6  may also be placed along the bottom of the Chassis  5  for compactness of unit, with the desired Wind Reversal effect  20  and back draft elimination to be the same. 
         [0053]    CWE Concept Element #6 
         [0054]    Servo Tabs and Rudder Weather Vane System  FIG. 13   
         [0055]    Small vertical fin/rudder tabs  10  mount vertically on an extension or dual rod extensions well out in front of the wind ramp leading edge to sample variations in the direction of the wind  16 , such as gusts, as they approach the CWE unit. The tabs  10  work to maximize the effectiveness of the entire unit by for maintaining alignment with the wind  16  for maximum efficiency in wind capture. This is based on the premise that the unit body is balanced on a vertical shaft bearing  17  and is free to rotate about the azimuth. As the tabs  10  upwind find a wind change, cable rigging or sensors will transmit that information back to servo tabs mounted on a free swinging large rudder and vertical fin assembly  4  for assisting the rotor assembly to weather vane into the best wind condition  16  constantly. A simpler version of the weather vane feature could preclude the use of upwind tabs  10  and hinged rudders  4 , and merely have large vertical fins mounted fixed on downwind extension pole supports for attaining relative wind orientation. Application of servo tabs  10  and rudder weather vane system  4  will be used on wind engines mounted to allow swivel and constant hunting for head winds  16 . Some application that has fixed chassis mounts will not require this feature. Wind farms that have predicted wind direction will not require this system  4 ,  10 . Design and configuration for CWE models are may be varied to achieve desired results. 
         [0056]    CWE Concept Element #7 
         [0057]    Anti-Icing System  FIG. 1 ,  FIG. 2 , and  FIG. 14   
         [0058]    The primary wind driven mechanical or electrical generating machinery attached to the PTO shaft  2  may also have an accessory drive case which can drive a small self-contained electrical source which, through electrical slip rings at the rotor axle  2  will power heated leading edges of the horizontal bucket blades  1  and the splates  15  outer circumference for anti-icing service (leading edge potential for icing depicted  13 ,  FIG. 14 ). Rotor rotation  9  centrifugal force will fling any ice that forms out and away at the backside exhaust area, to be shed downwind. All inlets that are part of the fixed ducting may be fitted with embedded leading edge elements for heating to allow continued reliable operation in freezing weather. Anti-icing for those leading edges  13 , the front of the wind ramp airfoil  11  and the top lip of the wind keeper baffle/cowling  8  could alternatively be supplied with pneumatic ice protection boots similar to those fitted on aircraft wings and fins leading edge surfaces. In addition, a small compressor may be driven at the accessory case to maintain compressed air in an accumulator tank built into the CWE chassis  5  for use in bad weather. Another ant-ice consideration could be to pump anti-ice fluid weep at the fixed leading edges, as used in aircraft technology innovation. All of these methods will be engineered to activate automatically upon ice buildup detection  13  and to ensure the CWE remains operation in icy weather. Anti-icing features will be installed only on models utilized on wind farms that are predicted to freeze during the winter months. 
         [0059]    California Wind Engine Concept Element #8 &amp; #9 
         [0060]    Rotor Brake System/Ramp Rpm Limiter/Overspeed Governor  FIG. 15  and  FIG. 16   
         [0061]    The CWE Rotor Braking System  3  will be utilized for maintenance, Rotor over-speeding, and emergencies. The CWE Ramp System  11 ,  12  to be built to allow the wind Ramp to rise or modify shape  12  to prevent prevailing wind  16  from striking the bucket voids  1 , &amp;/or retard the efficiency of the airfoil to reduce the driving force for rotating the Rotor. This action to be activated, controlled by a service technician. This process decreases the rotation speed of the CWE Rotor  1  assisting in slowing the Rotor to a complete stop. Wind Ramp  11  may be designed to move up into position to block the force of the wind at the Power Stroke sequence  16  of the Rotor above the Rotor Axle and at the same time expose an open area below the Axle level  12  providing means for the oncoming Wind Energy  16  to force against the lower, returning Bucket Blades  1 ,  FIG. 16 . Additionally, as part of the Braking System  3 , the hinged VAV Vanes  7  in the WRDS linear outside ducts  6  will operate to closed position, thereby preventing Wind Energy flow  16  from entering the WRDS duct  6 , aiding in the braking process. Once all rotation has come to a safe and complete stop, conventional fail-safe braking assemblies with the use of automotive style calipers and brake pads  3  binding against the Spill Plate  15  outer circumferences hold the CWE Rotor  1  stabilized, stationary for servicing. Specifics of the mechanical design are may be varied to achieve desired results. Also, prevention and control of high-wind-condition Rotor over-speed will utilize these systems automatically, controlled by the Over-Speed Governor for safety and structural consideration (not seen in Drawings). 
         [0062]    General Construction Expectations &amp; Comments 
         [0063]    Physical dimensions, shapes and materials of the CWE Elements may be varied with engineering and design teams based at various wind farms and to include end user&#39;s needs and geographical locations. 
         [0064]    1. Specific considerations will include:
       (A) Best ratio of rotor diameter- to rotor chassis, body and width.   (B) Wind ramp length, airfoil shape, and degree of approaching wind direction change within the ramp&#39;s area of influence, from horizontal to upward, toward the vertical.   (C) Venturi effect design and number of degrees of rotation of opening to downwind for used wind exhausting and “clock position” to flare past 12 o&#39;clock top-dead center.   (D) Size, length and shape of the Wind Reversal Ducting System.   (E) Size, shape and position of the rudder and weather vane fin(s) downwind and upwind directional sensor servo tabs as applicable may all be varied for most efficient design       
 
         [0070]    2. All materials to be incorporated into the structure of the CWE units may be varied to achieve desired results. Design lubrication systems and chassis unit pivot axle when required may be included. 
         [0071]    3. Existing Standard Material Engineering and Conventional Construction Means and Methods are to be incorporated into the unique design concepts as contained herein. Unit chassis and body, rotor bearings, monopoles or other types of towers, building mount conditions, PTO shafts, spline or key designs, types of generator or other machinery to be driven such as electrical power production, transfer of the power or product generated to get down to the user interface at the base of the tower or building is understood to be of conventional mechanical, electrical and structural means. 
         [0072]    4. The single-barrel horizontal placement of the rotor turbine described herein is used for an example. That horizontal placement and the described six each rotor buckets are not a part of this patent, only the nine concept elements are for efficiency enhancement described herein of such rotor installations. The assumption is the power stroke is from 9 o&#39;clock through to the top of the assembly with the rotor bucket at the top 12 o&#39;clock and past to the engineered number of degrees rotation where used wind begins exhausting downwind in these example descriptions. At the 6 o&#39;clock position, the bucket blades are rotating upwind and forward wind resistance is blocked and deflected upward positively by the shaping of the wind ramp airfoil. 
         [0073]    5. The CWE Design Concepts are for providing powerful and efficient delivery of the prevailing renewable wind energy down to the ends of the two PTO shafts with high torque values to be applied for useful work. That is the purpose of the present invention. 
         [0074]    Civil Urban Planning Departments, and Other Items 
         [0075]    1. The CWE overall concept has major green renewable wind energy capture for useful work uppermost in mind and the CWE “5” Rotor is much more environmentally friendly compared to many other wind capture designs already in place with regard to indigenous bird and nature populations in such assemble wind farms and building installations. 
         [0076]    2. Urban and rural planning departments should have a much easier task in reviewing and approving considerations for satisfying of the general publics&#39; need and aesthetic desires with the CWE Design. The CWE units will be offered in a variety of exterior finishes. The exterior fixed-type surfaces can be offered with painted murals, such as bluish skies with background white puffy cumulus cloud overlays for example, for pleasant eye appeal. 
         [0077]    3. Continuing the theme concerning urban planning departments, a large percentage of the CWE rotating-power-producing machinery (the turbine bucket assembly) is concealed behind the fixed chassis design ducting and cowling enclosures. For those units which are designed with the Omni Azimuth directional swiveling feature, that movement around the pivot axle will be no more noticeable to the public than natural weather changes of wind direction. Man sizes of the CWE are to be offered on the market. Large public utility wind farm units can be customized for the various quantities of winds extant at those diverse locations along with the de-icing/anti-icing options, and the Omni directional option, as needed. 
         [0078]    4. The CWE design lends itself to the possibility of mass production for resulting economies of scale similar to HVAC air handler fan units and similar units that are manufactured for building construction in urban areas for example. HVAC Direct Drive need could be driven directly by one of the rotor PTO shafts. Farm units in the Plains States, might be more utilitarian in appearance. The PTO shafts available at both ends of the wind rotor axle may be used to mount an air compressor on one end to supply compressed air to operate pneumatic tools for maintenance operations. The other end may be fitted for an electrical generator to provide stored electrical energy through rectifiers into a battery bank and shared electrical energy aiding in incoming public utility electric meter power. This will be a consideration for farm and rural use in particular. Multi-purpose and quiet, utility with reliability. 
         [0079]    5. Rural tornado-prone areas might have a tower feature that would allow the unit to “kneel” to the ground, or retract downward telescopically upon manual or automatic command, if such a storm threat appears.
