  • the first aspect comprises a funnel wind turbine associated with a building structure and comprising the roof thereof
  • a Funnel wind turbine in association with an extraction device whereby air can pass through the body of the turbine in a substantially vertical direction whilst the turbine is being driven by wind striking the turbine.
  • a turbine ( 1 ) in Fig 8&9 vertical also Fig 1 1&12 is horizontal which is associated with the design of a motor vehicle so that power to assist in driving the motor vehicle can be developed.
  • a turbine in an aircraft and watercraft which can assist in developing power for use in operation of the aircraft or watercraft.
  • the turbine of the invention is associated with a generator which may be either a DC generator or an AC alternator, and used to produce power which is either supplementary to or provides a main power source for a particular application.
  • the turbine can be used for different purposes, for providing power for an air or other pump but. except where this is necessary, I shall not further describe such applications.
  • the turbine of the invention can be associated with a roof
  • structure of a building such as a water cooling tower, silo, a water tank, a house, a factory or a building for use for other purposes.
  • the actual roof can be constituted by the lower surfaces (2) in Fig 2a.2b.3a&3b of the funnel of the invention.
  • the roof structure of building is replaced by the vertical dividers (4) in Fig l,2a.2b.3a&3b of the funnel wind structure. Since the walls (4) in Fig 1.2a,2b,3a&3b of the funnel acts as a roof trussed.
  • the roof may have a high point at which the turbine ( l)in Fig 2a.2b,3a,3b is located and may be directed downwardly and outwardly therefrom.
  • the roof (2) in Fig 2a,2b,3a&3b may comprise a number of panels, in most cases be flat and which has adjacent panels, each of which are at an angle to the first panel so that, generally, the panels comprise a conical member having a number of flat surfaces.
  • the number of these will depend on the number of funnels example in Fig 2a.2b,3a&3b.
  • the combination of( l)(2)(3)(4) is an example of a funnel required for a particular application
  • the roof structure could be in the form of a truncated cone so that the floor of each of the funnels is in fact curved.
  • the adjacent funnels are separated by vertical dividers(4) in Fig 2a.2b,3a&3b which are located between the upper(3) and lower(2)in Fig 2a.2b 3a&3b members and which again terminate in a height equivalent to the required throat height for the turbine( 1 )in Fig 2a.2b.3a&3b.
  • dividers (4) as in Fig 2a,2b,3a&3b can be symmetrically placed around the turbine( 1 ) in Fig 2a,2b.3a&3b or they could, if required, be associated with a roof and mirror image structure which is offset so that the outlet throat is at a required angle to the periphery of the turbine to provide maximum energy transfer thereto Because of the structure, the turbine( l ) in Fig 1.2a.2b.3a&3b is adapted to operate in one direction and to have the throat offset from the axis, to drive the turbine in this direction may be desirable.
  • the incoming air stream will strike and enter the funnels which are directed towards the airflow.
  • the number of funnels so directed will depend on the actual total number of funnels but will be generally those which are in about 180 degrees transverse to the wind flow
  • the wind striking the funnels will be guided inwardly to the required throat so the quantity of air which passes through the turbine( 1 ) in Fig l,2a,2b.3a&3b will be substantially greater than would have been the case if the turbine had simply been open to atmosphere.
  • the efficiency of each of the funnels will vary from maximum efficiency from the funnel which is directed towards the flow, to minimal efficiency to the one which is on the edge of the area of contact.
  • the turbine( 1 ) in Fig 1.2a,2b.3a&3b acts as a restriction to general air movement, other than that which passes through the funnels and through the turbine( l ) in Fig l,2a.2b,3a&3b. the pressure on the downwind side of the turbine tends to be somewhat reduced and this means that the transfer of energy as the wind passes through the turbine is maximized as the back pressure is minimal.
  • the actual roof can be constituted b ⁇ lower surfaces of the funnel (2) of the invention
  • the support structural of the roof is the dividers (4) in fig 1.
  • fig 2a. 2b. 3a and 3b Also the upper surface of the funnel (3) and (3 a) in fig 2a, 2b, 3a and 3b, when these are combined the structure is sound, when all the funnels are combined it becomes self supporting and no more support is required
  • 3a and 3b is not required to be centre of the funnel Therefore due to location and purpose of the building it can be designed in away to take advantage of wind energy by funne ng it to the turbine ( 1 ) also using the lessor pressure on the opposite side of the building (7) as in fig 2a. 2b. 3a and 3b so it can be exhausted Also it mav be said that a concave roof 3a in fig 2b and 3b As extra advantages the shape could be used to reflect heat to a central point ( 13) in fig 2b Therefore the roof becomes a solar heater It could be said that shape of the buildings also could be designed to allow the wind load on building (7) as in fig 2a. 2b. 3a and 3b to pass through it in a controlled funnel or duct and using the funnel wind principle to harness the energy for the building (7) as in fig 2a, 2b. 3a and 3b
  • This arrangement is particularly suitable for ventilating such areas as tunnels where there can be a build-up of carbon dioxide as vehicles pass through these, or because of the ambient condition there can be build-up of other gases, such as a in a
  • turb ⁇ ne( 1 ) in Fig 4,5. &6 is built around an annular truncated con ⁇ cal( l ) in Fig 5 member located vertically with its larger diameter end adjacent to the top It could be coated so as the air or gases passing the surface a static charge is created This charge could be used to reduce harmful gas emissions
  • the internal portion of the conical member can be provided with what is effectively an inwardly directed Archimedean screw, arranged, or internal blades(9)in Fig 4&5 in the normal direction of rotation, to act as a screw pump to draw air from the lower end of the turbine upwardly
  • the arrangement is such that the device opens into the area to be evacuated.
  • the turbine( 1 )in Fig4,5&6 is exterior to the tunnel, and may be equivalent to or many stories high, and under effectively any circumstances, the turbine( 1 )in Fig 4.5&6 will be caused to rotate even if the wind speed is only slight, and the rotation of the Archimedean screw internal blades(9 in fig 5&6) will cause air to be drawn up into the cone from the tunnel.
  • this air pressure will tend to reduce as a it gets closer to the outlet, so that when it is delivered to the outside air it will be basically a low pressure, slowly moving air volume.
  • This arrangement can thus generally provide a power use-free method of ventilating substantial areas and of course depending upon the size of the area, so we shall vary the size of the turbine.
  • the inlet to the device could be adjustable to control the amount of air passing through and if this is to be restricted. then the additional power generated could be used to drive a generator for electricity or the like.
  • a turbine( 1 )in Fig 8&9 vertical and Fig 1 1 &12 horizontal of the type described in association with a motor vehicle Therefore instead of designing motor vehicle to allow airflow to pass over and around.
  • the shape allows the air flow to pass through the vehicle which turns a turbine ( l)in Fig 8&9 vertical and Fig 1 1 &.12 vertical or horizontal.
  • the design of the motor vehicle may be such that the upper(l l )in Fig 7,8.9, 10.1 1& 12 surface of the cabin can also it could be said that the motor vehicle has solar panel on the surface. Also as a combustion motor which run on hydrogen( 10)in Fig 8.9& 1 1 Therefore a hybrid system can be provided.

  • the arrangement may be such as a to act optimally when the wind is coming directly from the front of the vehicle.
  • there will be a side vector component and this may strike the funnels at a direction offset from the straight ahead.
