Abstract

This is a devise for capturing and accelerating wind over a wide range of potential vector angles of incidence. The main (but not exclusive) purpose of this invention is the capture, focus and acceleration of a large volume of wind and to direct that hyper wind onto a commercially obtainable wind turbine for the purpose of generating electrical power. The primary (but by no means only) intent is to make available effective on site electrical generation for the general populace. The overall and interactive elements of this invention through the use of a wide orifice of collection and strategically placed planes and diverters will facilitate the capture of a preponderance of yearly local ambient wind impinging upon the invention over a wide range of environmental contexts. Additionally the act of constricting wind through the facility of strategically configured panels effectively focuses &
accelerates the available wind by the agency of the Venture effect and in accordance with the Bernoulli formulae. This hyperactive wind force is then channeled towards a wind turbine. A finale rear acting reverse funnel will add a further boost to the kinetically hyperactive wind. Virtually all wind turbines are rendered considerably more productive through the increase of wind speed as the mathematical relationship dictates that a small increase in speed will have a power increase of three in electrical energy production. The flexibility of this invention facilitates the use of any of the wide variety of wind turbine configurations available currently and in the future.
Some examples of suitable configurations which may favorably integrated with this invention are exemplified (but by no means limited) to the following: a propeller type of horizontal axis drive turbine;
a horizontal airfoil turbine with a vertical axel; or a horizontally notating paddle wheel type turbine spinning around a horizontal axis;
or a vertical axis cone shaped turbine physically connected to the roof for support or floating magnetically. The throat shape at the terminal end of the 2nd segment referred to as the 'Accelerator Chamber'; the 'Enclosure Chamber' and the opening orifice of the rear booster funnel or 'Enhancer Chamber' of this invention may be configured with various dimensions and shapes, within limits, as deemed most suitable for the type of turbine to be purchased and conjoined with the roof top accelerator.

SPECIFICATIONS
1) General character:
This is an invention for the purpose of capturing breezes impinging upon the invention from a wide range of directions and then through the implementation of the Venturi effect speeding up the breeze so as to increase the amount of electrical current, which a commercially purchased wind turbine will be able to produce.

Description

2) Nature of the currant state of conditions which render the need and utility of the invention herby put forth.
It is desirable for urban as well as suburban homeowners building owners to be able to augment or replace the electrical power available to them as provided by the local power company. The general method for employing the wide variety of either vertical or horizontal axis wind turbines is to install them on towers ranging from 50' to 150'. This is not only an extremely costly process but has been rendered virtually impossible by the height restrictions generally imposed by local government entities.
Further impositions imposed by the objections of neighbors for reasons of esthetics and noise effectively eliminate or greatly restrict the installation of wind turbines even when attached to short towers or even roofs or at the sides of buildings. An even further debilitating problem with urban installations derives from the fact that breezes in an urban environment are greatly diminished and flow becomes divergent by obstacles. Further problems derive from the fact that the natural quality of unattended wind is to frequently and rapidly change direction. The required low altitude placement along with the obstacle problems and direction changes results in urban wind speeds of such low velocity and poor quality, as to render prior methods of utilization miniscule in result. This invention overcomes virtually all the above mentioned difficulties by using an esthetically pleasing configuration which will capture a larger volume of wind; focus it into a uniform stream;
accelerate it towards one direction and then bring it to bear upon a strategically placed wind turbine in a fully enhanced hyper state through the implementation of the Venturi effect both fore and aft of the turbine. Previous attempts to utilize Venturi and Bernoulli physical principles have proven of limited utility and effectiveness because these attempts have generally tried to affix baffles to the turbine, which becomes the primary support of the intensifier. This invention works because it rather turns the solution around by using the capturing and intensifying system as the support.
Because of the configuration of this invention sound attenuation is inherently accomplished but additionally because of its flexibility greater levels of sound insulation are made readily attainable. it should be added that every installation would inherently vary to some degree from the preferred embodiment as it is anticipated that angles and sizes as well as materials are suitably adaptable to the functionality of this invention in accordance with the dynamics of any particular situation.

3a) The Inventive Idea This invention relates to a method for capturing wind at some suitable part of a budding or near a building. The preferred configuration being that of the top of any building in any habitable context, and will be of most advantage in an urban setting. Through the use of a wide frontal orifice or scoop;
consisting of 4 panel surfaces sloped so as to render the front orifice considerably larger than the terminal orifice. Also a central Fore Fin Diverter protruding somewhat past the plane of the orifice an enhanced volume of wind may be captured. The wind wafting in a general direction towards the device is first captured and then focused into the second chamber referred to as the Venturi accelerator. The utility of the invention will be highest when the central axes of the device is pointed in the direction of the most consistently, predominantly yearly wind flow of the building site. This may be clearly and effectively determined through the use of a wind rose diagram of the area or site specific. The impinging breeze which may be approaching the scoop segment of the invention from any direction within a range of approximately 1800 depending on the angles of the flanking scoop surfaces and the configuration of the central Fore Fin Diverter will be captured and directed into the Venturi Accelerator segment. The Venturi Accelerator segment will through the agency of the Venturi effect greatly increase the speed of the captured wind. The Venturi Accelerator will not only greatly increase the speed of the wind but will also act through the agency of constriction and focus and straighten the flow of wind by greatly diminishing any flutter or eddy effects and bouncing the flow into a uniform direction. The wind will be converted into an essentially unidirectional uniform stream directly at the wind turbine. The wind turbine centered at the plane of the terminal orifice will be able to receive and utilize the hyper energized and uniform wind flow to produce a greatly enhanced quantity of electrical energy. The wind after passing by the wind turbine will then continue through the postern Venturi funnel in reverse, which will further enhance the flows kinetic energy. The most irrefutably unique aspect to this assemblage is the Fore Fin Diverter. This artifice enables the invention to capture a more diverse range of impinging wind angles. Even winds approaching at an obtuse angle to the horizontal axis of the mouth (50) of the scoop will be captured and diverted back into the maw of the Venturi funnel, at a substantially increased volume. It is the additional artifice of the concave surface of the Fore Fin Diverter by employing the principle of angle of incidence being equal to the angle of reflection which enables this device to more effectively divert even those oblique winds back into the Venturi accelerator tunnel so as to effectively direct those otherwise lost breezes into energy production. This process is enhanced by the inherent quality of wind which tends to reflect in more of an arc formation than a strict angular bounce as indicated by the wind vector lines of action (20b). This will tend to cause a smoother and more focused diversion and linearity as the Venturi funnel constricts the wind towards the wind turbine. Conversely, breezes impinging upon the assemblage from an approximately parallel direction to that of the central axis will be virtually undeterred from their passage to the Venturi accelerator section because of the curved nose configuration of the Fore Fin Diverter due to the tendency of wind to flow around curved objects with very little vector divergence.

3b) Improvements rendered by the invention:

The improvements that this invention renders first of all come in the fact that the effective air mass is increased by the concentration of the wind impinging on the large area of the scoop, which is focused into a small area at the face of the turbine blades. I have found through study of wind rose diagrams that most localities have distinctly predominant wind patterns. In actuality wind patterns are generally limited within a directional vector of 120 to 180 . This fact enables the invention to effectively utilize the preponderance of available wind potential for virtually any building site.
Secondly, the location of the invention on the roof of the budding and the fact that the upper segment may be considered by most civic statutes to be an appendage of the building and not solely the building itself will thus take advantage of the maximum height enhancement that conditions and civic regulations would allow.
Thirdly through the inherent funnel shape of the chamber the Venturi effect is employed to increase the speed of the wind. Additional improvements are derived from the fact that the turbine in the configuration of the invention becomes hidden and virtually indistinguishable from the roof like assemblage. Noise problems are diminished because the scoop and Venturi tunnel covers half the wind turban blade exposure. Additional sounds baffles may be placed flanking the turbine for further sound attenuation at the constricted tunnel segment (10). Other advantages include the fact that the wide range of angular capture of wind without the necessity of turning always for the fixing of the structure and the inherent rigidity and stabilities this allows not only for the main assemblage but also for the wind turbine. Considerably less wear and tear and also considerably less noise will derive from the fact that all the elements of energy production can remain fixed and stable in one direction (save for the fins of the wind turbine itself of course). The length and size of the funneling surfaces can more effectively focus and hyperactivate breezes as size limitations of previous incarnations no longer apply.

4) BRIEF DRAWING DESCRIPTIONS:

While the drawings are not necessarily to precise scale all objects are relatively proportion to each other.

5) DETAILED DESCRIPTION OF DRAWINGS
Figure 1 In the enclosed drawings, which illustrate some of the various embodiments of the invention; Figure 1 is a perspective showing the invention installed onto a generic structure such as a home;

-Element (1) constitutes the left vertical wind scoop panel (as one faces in front of the Fore Fin Diverter's (5) widest edge (5c) looking back towards the narrowest edge (5d)).
This panel may be placed at any suitable angle to the central axis (50) within the limits of 89 and 1 . The lip or frontal edge of this panel (1 a) has flexibility as to its configuration from curvilinear to rectilinear to planer to polygonal. The preferred embodiment shown in the drawing illustrates the panel positioned perpendicular to a supporting roof (34). In this configuration it can most practically be attached and braced to the roof structure and to the other invention segments to which it is attached. The angle of the main panel surface as it spans from fore lip edge (1a) to its terminal edge (1b) should be strategically placed so as to appropriately accommodate the primary wind vectors and significant site factors over a years wind vector variation. The most advantageous situation would be to accommodate the median and mean wind vectors over the year for the site under consideration while factoring in all the particulars of the site such as cross street configurations; nearby structures and wind effecting vegetation. The resulting function of seasonal variations should result in a determination of volume capture maximization. Also structural rigidity and esthetic predilections should be factored in as determinants of the final shape and direction of this panel.
The final disposition of panel (2) and the relation of fore lip (2a) and terminal edge (2b) can be determined in the same fashion as panel (1). It is undesirable and unnecessary to attempt to encompass all winds as illustrated by the most relevant wind rose diagram.
Winds are once again extremely variable from moment to moment and other systems, which attempt to be totally accessible to all the vicissitudes of wind direction, not only fail at this but also suffer a number of ancillary debilitating effects. It is functionally suitable to find a medium angle, which will capture a preponderance of wind directions. Another consideration to be taken into account is the fact that the closer the angle formed by (1) and (2) to the limit of 90 the more diminishment in effectiveness the invention will realize in electrical production. Panel (3) acts as the top horizontal capturing plane. It may again assume a wide variety of shapes and angles from curvilinear, rectilinear to polygonal to flat. In the preferred embodiment illustrated in figure 1 it is flat and perpendicular which facilitates its uniform closure with panels (1) and (2). This also facilitates a rigid and structurally sound installation.
Lip (3a) can be angled to that of the central axis (50) within a range of 89 to 1 with the limitation that the fore lip (3a) is to remain further away from the central axis (50) than (3b). In the preferred embodiment illustrated by Figure 1 the panel is shown to decline from front to back at approximately Panel (4) is the bottom plane of the scoop. Its shape determining factors closely match those of panel (3) Element (5) in Figure 1 is the Fore Fin Diverter.
As previously mentioned the most distinctive and unique aspect of this invention is the use of the Fore Fin Diverter. The Diverter is the element which enables even a wide angled mouth configuration to effectively capture, focus, enhance, and employ all but the most divergent wind vectors impinging upon the invention.
The Diverter is a vertical fin like element, which may be located anywhere within the plane of the scoop frontal orifice. It may be configured at any angle to the edges, which border the plane of the frontal orifice and may extend at any distance. The preferred embodiment as illustrated in Figure 1 is for the Fore Fin Diverter to be located and directed Wong the central access of the invention (50). It is configured to be perpendicular to panels (3) and (4). In this configuration it can act as a structural column transferring load all the way to the ground and providing rigidity to the 2 attached panels (3) and (4). It extends out beyond the scoop's frontal orifice for a few feet.
This configuration serves to enhance the volume of obliquely impinging wind vectors. The more the diverter protrudes beyond the plane of the frontal scoop orifice (1a, 2a, 3a, & 4a) the more divergent wind vectors may be captured.
The limits to this protrusion will be determined by community setback regulations and the esthetic precepts of the owner of the building. The front nose of the Diverter (5c) is configured in a semicircular arc. The flanking walls to either side (5a, & 5b [see Fig. 2]) are concave when viewed from their exterior. The final arc radius of the two walls will be a function of the width, deployment angle and the most extreme angle of wind vector that is deemed to be accessible. The terminal edge (5d) should be as small as possible in order to render the entire configuration as aerodynamic as possible and as structural considerations will allow.

Figure 2 The secondary tubular configuration behind and uniformly attached to the scoop (1, 2, 3, & 4) is the Venturi Accelerator Chamber (here on referred to as the Accelerator Chamber) consisting of 4 panels (6,7,8, & 9)(see also Fig. 3). The finale shape, and dimensions will be determined by the functional considerations of the shape of the Scoop's terminal orifice; the shape of the turbine rotor (or paddle) sweep; the aerodynamic qualities which are mathematically determined to produce the highest 'hyperization' with the lowest flutter and drag and with consideration given to structure and cost. In the preferred embodiment illustrated in Figure 2 the Accelerator Chamber is formed into a rectangular smoothly decreasing funnel shape with panels angled at approximately 30 from the central axis.
Another determining factor in the overall linear dimension along the central axis of this chamber is the sweep of the wind turbine configuration, which will be selected to conjoin with the invention. The aft edges are to just comfortably encompass the sweep of the paddles or blades of the wind turbine with a margin of setback to accommodate torque or bend. The angle of the chamber walls then becomes a function of the limiting factors. It may very well be found upon further testing that a particular site wind vector condition may determine a series of ovular tubes of uniform dimension with a size diminishment and shape morphing to be embodied by the series of concatenating tube segments.
This configuration may be advantageous, as some research has suggested. The other 3 panels are to form a complete enclosure arrayed symmetrically about the central axis (50). Again they may each form distinct curvilinear, rectilinear or polygonal surfaces forming a funnel like shape with the primary limitation that the fore lips (6a, 7a, 8a, & 9a) are further away from the central axis (50) then the aft edges (6b, 7b, 8b, & 9b). Again as previously mentioned the formation of the Accelerator Chamber may be found to advantageously consist of a series of uniform tubes with diminishing sizes in concatenation with indistinct panels.
The following series of panels attached to the Accelerator Chamber's aft edges (6b, 7b, 8b, & 9b) form the Enclosure Chamber. The Enclosure Chamber is preferably configured with 4 distinct panels (10, 11, 12, & 13) of a rectilinear nature. A curvilinear configuration may under certain circumstance deemed advantageous. The main purposes of this camber are to facilitate the hyper flow of the incoming winds; and also to diminish any noises produced by the wind turbine, which it surrounds.
The sides are to be placed just back of the turbine paddles or blades with margin provided for potential torque, bending and drift. The length of the panels along the central access will approximately be sufficient to totally enclose the sweep of the turbine's blades or paddles as well as the turbine body.
Following the Enclosure Chamber (10,11, 12, & 13) comes the Augmenting Chamber consisting of four panels (14, 15, 16, & 17). The configuration and dimensions of the element are also flexible within the parameters of a required increasing of size from fore to aft, which must fit structurally and esthetically and aerodynamically to the proceeding series of chambers. The purpose of the Augmenting Chamber is to utilize the physics of the Venturi principle as brought to bear by the Bernoulli functions to further accelerate the wind traveling through the invention. The general interpretation of these principles dictates that the best configuration of this chamber would be a truncated cone shape measuring 2 to 3 times the length of the preceding Enclosure Chamber. The Augmenting Chamber in this embodiment will be centered by the central axis.
Both of the orifices (14a, 14b 15a, 15,b, 16a, 16b, 17a, & 17b) are to circumscribe a plane perpendicular to the central axis. The angle of the cone walls to that of the central axis will be between;
15 - 30 .
Circumstances and economics may dictate that a rectilinear chamber formation be used. This may prove suitable but aerodynamic factors and the Bernoulli functions should be referred to in the process of making this decision.
Also in this view are shown the placement of a typical commercial wind turbine (in this case a vertical axis turbine) (20); the pole and splayed leg stanchions for support as well as the horizontal braces (22a, & 22b). Panel (12) from the bottom of the Enclosure Chamber has been left out for the purpose of showing the turbine legs (21) and the horizontal braces (22a & 22b) Figure 3 Shows all the elements previously mentioned. It also illustrates the placement of a typical commercial wind turbine (in this case a vertical axis turbine) (20). Also shown is the support pole and angled stanchions (21) All the surfaces of the invention should me made weather proof utilizing the same or similar method of weatherproofing as that employed by the building to which the invention is to be attached. All The inner surfaces of the collecting cone (1 a, 1 b, 2a,2b,3a, & 3b) should all be of a smooth surface, which is congruent both functionally and esthetically to that of the associated building. Attachment of tall the elements of the cone and that of the cone to the building structure should be dependent and congruent to that of the associated building. In general the preferred embodiment would be that of either steel or wooden studs which are screwed or nailed together in a standard structural system as determined by the ruling code of the site context. Bracing should be employed again as determined by the building code of the community; with preference being given to the variety of approved Simpson metallic bracing products. Weatherproofing of the outer exposed surface may be by any suitable material but in the preferred embodiment an application of EPDM
rubberized weatherproofing can be effectively utilized for both the inside and outside surfaces as well as the associated building roof. This would result in a uniform weather proofing system, which would function effectively and produce an esthetically positive effect. In whatever material and system weatherproofing is to be performed esthetic considerations are of major consequence to the acceptability of the entire system of building & invention.

The vertical concentrating cone elements (2a) & (2b) should be affixed to all other elements as well as the building structure as previously mentioned. The configuration of these two elements is more restricted than that of the scoop elements (1 a & 1 b) in that the angle they form with each other needs to fall within the range of 30 to 45 and they should be symmetrically displaced about the central axis of the invention as determined by the central axis of the wind turbine (6) which has been selected for the particular installation in question. The configuration of the wind turbine and in particular the axel direction will have the most direct bearing upon the shape and size of the funnel opening (5). All types of turbines may be accommodated with only moderate adjustments to the finale orifice of the venturi funnel. Vertical axis turbines maybe accommodated by sizing the terminal orifice to coincide with the sweep of the paddles configured around the axis. A pole with triangular 45 stabilizing legs can be used to firmly affix the commercially purchased horizontal axis turbine to the roof with stanchions and appropriate screws. Further stabilization from the pole extender to the horizontal panel of the venturi tunnel terminal orifice would be further encouraged in the preferred embodiment.
This would be most efficaciously accomplished through the use of a horizontal tubular metal attachment extending perpendicular to the central axis of the device with sufficient length to be able to affix a pair of horizontal stabilizing metal tubes in an approximately parallel direction from the cross tube brace under the paddles back to the reinforced venturi tunnel terminal orifice. This may be accomplished with suitably formed brackets and screws. When a propeller configured horizontal axis turbine is chosen all other elements would essential remain the same. The primary changes would be in the fact that the venturi terminal orifice would be sized and shaped to make the orifice open to the full extent of the blades with a minimum of wind blockage. A more circular rather than rectangular shape given to the terminal orifice would be preferable but not really of substantial bearing. Also there would be a requirement to tighten up the gimbals on the turbine which allow the blade and axle assembly to rotate horizontally which is usually a capacity afforded most such devices so that they will be continuously faced into the wind. This necessity is obviated by the invention, as is the illumination of the deleterious effects that derive from this act of repeated rapid directional gyration. A horizontal axis turbine may be suitably installed with the appropriate adjustment of the terminal orifice to encompass the full sweep of the blades and the disengaging any horizontal wind gyration gimbals which the turbine system may contain. The new magnetically levitating cone shaped turbine may likewise easily accommodated by the employment of a suitably uplifting platform attached to the roof upon triangulated stanchions as previously described and horizontally braced again as previously described.

It should then be sloped down in one continuous surface to the terminal mouth of the venturi augmenter so that the terminal edge is in line with the top edge of the paddle or propeller sweep and sufficiently back from the edge of the sweep so as to prevent any collision of the paddles or propellers with this edge. To this end some torque should be accounted for in the spin of the paddles or props, but aside of this margin of safety the other edge should be placed as close to the sweep of the paddles or propellers as practical. The finale angle of the top plan will ultimately be a function of the height of outer lip (1b) and (3b) and the distance between the out lips and the terminal mouth edges (5a, 5b, 5c, & 5d) As previously mentioned the ultimate exact dimensions and configuration of the assembly can maintain a certain degree of flexibility within the ranges of utility determined by site conditions and the angles of the 4 planes of the device which have upper and lower limits as previously prescribed.
