Patents Form # 5 NEW ZEALAND Patents Act 1953 COMPLETE SPECIFICATION AFTER PROVISIONAL 579564 DATED: 9 September 2009 TITLE: Fluid Driven Generator We, 1) HOSEGOOD, David Andrew 2) HOSEGOOD, Christine Helen Address: 1) C/o Seaview Marina, 100 Port Road, Lower Hutt, New Zealand, 5010 2) C/o Seaview Marina, 100 Port Road, Lower Hutt, New Zealand, 5010 Nationality: 1) New Zealand 2) New Zealand do hereby declare the invention for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement: FEE CODE - 1050 Received at IPONZ on 12 December 2011 Fluid Driven Generator Field of Invention The invention relates to a fluid driven generator, typically a wind powered generator, for producing electrical power.

Background of Invention Fluid powered generators are known and widely used, such as water and wind powered generators. These known generators utilise turbines and gear boxes to produce and control the speed of the turbine which can place severe limitations and stresses on the generator, especially in situations of high wind. Normally in the advent of high winds wind powered generators have to be shut down to avoid damage to the wind generator. In high winds, especially high wind gusts, gear boxes in the generators cannot handle the stresses and the strains of such wind gusts which can result in the gear boxes can actually completely disintegrate, thus rendering the wind generator useless.

Current solutions for generating electricity is by mounting very large wind turbines in prominent places on the side or peaks of hills to take advantage of the available wind to generate electricity. Other power generation solutions are • To use coal fired installations, not clean and green • Thermal installations such as geothermal installations • Diesel powered j et turbines • Hydro power generation • Solar cell installations are not currently or widely used in New Zealand as they are deemed to expensive to set up • Nuclear power Hydro power generation, solar power generation and wind generation fall into the category of being renewable resources..

Small wind powered generation devices for home units incorporated with solar cell back up and grid connection are currently known, but not widely used, mainly due to reliability and high set up cost.

The actual size of the current wind generators to date, is only one of the problems as a small unit 1 Received at IPONZ on 12 December 2011 currently can produce 6 kilowatts of power, at full power and weighs approximately two and a half ton.

The larger wind turbines have huge towers and although they have the capacity to generate large amounts or power they spend a lot of time off line due to maintenance and insufficient winds. Though in high winds they are switched off and feathered The current cost of wind generator components is expensive as the components are generally not manufactured in New Zealand and have to be shipped to site from overseas manufacturers As mentioned previously gearbox failures are a great possibility. So a regular maintenance regime is strictly adhered to reduce down time.

In New Zealand and elsewhere in the world the wind generators are at the mercy of high winds. High winds render the wind generators inoperable, in fact when these conditions occur the wind generators are switched off and the blades are feathered and turbine constantly kept facing the wind to ensure they do not run out of control. If however this control is lost the blades will over run the unit and disintegrate and destroy the tower Sometimes the opposite of high winds can occur. Such low or lack of wind creates its own problems, especially for the large wind turbines as these require an electric motor to start the unit rotating once the winds are constant are able to maintain that momentum.

Another problem with wind generators, especially the large wind turbines is the noise they make. The tip speed of turbines is quite excessive and creates noise (a thumping or swooshing noise).

Blades have to be constantly checked for stress fractures. Stress fractures have been discovered in all or most of the wind turbines although the public are generally not told of this problem they are consistently being repaired by fibreglass experts that are part of the general maintenance teams and inspections.

With small wind generators they are not easily upgradeable, thus if a particular unit does not produce the desired power output it has to be replaced with a new unit that does. Also the units have to be maintained regularly, thus providing a high maintenance cost. 2 Received at IPONZ on 12 December 2011 All devices that rotate and are of a considerable size have to be maintained and the current design and nature of the construction of the current wind generators is extremely high and starts to erode in to the benefits of having wind powered generators.

As for the smaller wind powered devices they are not upgradeable and are extremely costly to set up and are generally used for the remote installation or farmer who needs power in a remote situation.

Wind power generation for the home is said to provide about 25 to 30 percent of power. What is needed for this to happen is a decent power supply provide by a wind generator, decent Ups-inverter and a good rectifying system or control system to manage the system. Too many people are led to believe that the adding of a wind generator to a house will solve all their power problems.

However current configurations do not help, with the size and price they become cost prohibitive. So a small system of the current type could cost in excess of twenty thousand dollars as all wind generating devices need to have some form of storage facility such as decent batteries to handle the loads expected for when there is no wind for as much five days or more supply.

The systems are also recommended to have a solar cell system to add charging capacity for those windless days especially when not connected to the national grid, for example in a remote farm installation. These installations are expensive and tend to be beyond the average citizen from purchasing said devices.

It would seem that at present current research has not been able to solve all the current difficulties associated with wind powered generators, or found or developed a wind powered generator that has a much broader commercial use than the current known wind powered generators.

Description of Drawings The following description will describe the invention in relation to preferred embodiments of the invention, namely a fluid driven generator, typically a wind powered generator, for producing electrical power.

The invention is in no way limited to these preferred embodiments as they are purely to exemplify the invention only and that possible variations and modifications would be readily apparent without departing from the scope of the invention.

It is envisaged that wind powered generators subject of the invention will be cheaper and more efficient and easier to install and set up and more attractive for the average citizen.

The wind powered generator of the invention will subsidise the existing power usage with not just a monetary return, but also overall 35 to 45 percent reduction in power usage from the national grid and in a high wind regions be able to supply power back to the national grid.

The wind generator is able to be upgraded as the kilowatt range can be increased with the addition of further coiled array.

With the aid of a PLC and a Grid tie the wind generator is able to be self controlled and at the same time monitor the batteries, the load feed power back into the national grid.

Figures 1 to 13 show a preferred embodiment of the invention, namely a wind driven generator, however it is envisaged that the generator could be driven by other fluids such as water either in hydro or tidal environment without departing from the overall scope of the invention.

The wind generator 10 includes radially spaced blades 60 attached via spokes 70(only one pair shown) to a fluid generator drive unit 40 mounted to a vertical support 37.

The generator unit has an outer housing 40 with at least one stationary radial coiled array 21, at least one rotatable magnetic hub 30 in which the radial coiled array is situated therein.

The magnetic hub 30 is attached to the outer housing such that as the outer housing 40 is caused to rotate as a result of the blades 60 being driven by the wind, the magnetic hub 30 rotates around the 12 Received at IPONZ on 12 December 2011 radial coiled array in order to produce electrical power.

Turning to figure 2 which shows a coiled array arrangement for producing low to medium voltage electrical power. The radial coiled array 20 consisting of 42 equally spaced coils 24 (all shown) extending radially outwardly from a central axis 23. The 42 coils are arranged into six groups Al-G1, A2- G2, A3- G3, A4- G4, A5- G5 & A6- G6 of seven coils each.

Coil A1 is connected via connection 25 to coil A2 which is connected via connection 26 to coil A3 which is connected via connection 27 to coil A4 which is connected via connection 28 to coil A5 which is connected via connection 29 to on coil A6 which completes one phase, This is repeated for the other coils for groups one, two, three and four. Similarly groups five and six can be connected in a similar fashion as well.

The seven group phase outputs A' to G' are connected to a bridge rectifier R. The circuit diagram for the rectifier R is shown in figure 11. The rectifier R enables a low to medium voltage of 12 to 68 volts of electrical power to be obtained per coil array arrangement shown in figure 2.

It is envisaged that other connection arrangements and configurations can be achieved in order to achieve a desired voltage and/or amperage output or a desired number of phases. For example for a three star Delta arrangement each connected coil in a group is 120 degrees apart and creates a 3 phase output.

Turning to figure 2A which shows a coiled array arrangement for producing high voltage electrical power. The radial coiled array shown in figure 2A consists of 42 equally spaced coils 24 extending radially outwardly from a central axis 23. The 42 coils are arranged into three groups A1 - A14 B1 -B14, CI - CI4, of fourteen coils each.

Coil A1 is connected via connection 201 to coil A2 which is connected via connection 202 to coil A3 which is connected via connection 203 to coil A4 which is connected via connection 204 to coil A5 which is connected via connection 205 to coil A6 which is connected via connection 206 to coil A7 which is connected via connection 207 to coil A8 which is connected via connection 208 to coil A9 which is connected via connection 209 coil A10 which is connected via connection 210 to coil All which is connected via connection 211 to A12 which is connected via connection 212 to coil A13 which is connected via connection 213 to A14 which then completes one phase. This is repeated for the other coils for groups, i.e. the B group and C group. 13 Received at IPONZ on 12 December 2011 The three group phase outputs A' to C' are connected to a bridge rectifier R. The circuit diagram for the rectifier R is shown in figure 11 A. The rectifier R enables a high voltage of up to 180 volts of electrical power to be obtained per coil array arrangement shown in figure 2.

The magnetic hub includes 56 equally circumferentially spaced apart magnets such that magnets are adapted to align with every fourteenth coil.

Each radial coiled array has a heat sink and one or more 500 volt bridge and control cct rectifiers labelled 1 through to 7 (see figure 11 A) a sizeable amperage and voltage coming out of one array.

A wind generator with a single radial coiled array and magnetic hub combination produces 700 watts of power with an excess of 120 -180 volts.

Figures 3 and 12 show two types of coiled array arrangements, figure 3 shows a two stacked coiled array arrangement 21, 21' and figure 12 a three coiled array 21, 21', 21 "stacked arrangement.

For (fig 3) 20 the two stacked arrangement there would be required two magnetic hubs and similarly for the three stacked arrangement three magnetic hubs (fig 13).

The two stacked arrangement shows two radial coiled arrays 21, 21' stacked apart on a shaft 22 along central axis 23.

The stacked arrays 21,21' above a base plate 47 and situated above a vertical support 37.

Each array 21, 21' is adapted to be stationary relative to each respective magnetic hub 30 (figures 4 & 5) and is adapted to fit with the magnetic hub 30 such that the outer face of the coils 24 are aligned in the same plane as the magnets 32 on the magnetic hub 30.

In figures 4 & 5 there is shown more details of the magnetic hub 30 as it is in respect of a two stacked radial coiled array. An upper magnetic hub 31 sits on top of a lower magnetic hub 31' such that in use both hubs rotate in unison.

Each hub 31, 31' has 48 equally spaced apart magnets 19 which in use align in the same plane as the radial coils such that as the hubs rotate each magnet 19 of the hub rotates pass each coil 24 of 14 Received at IPONZ on 12 December 2011 the corresponding coiled array.

The upper hub 31 has a shaft 33 that slides and fits within an opening in the lower hub 31 such that the two hubs can be stacked together. The opening has bearings 34, preferably: magnetic bearings.

The lower hub has a shaft 35 that fits within a bearing lined opening 34 in the vertical support 37'such that the hubs are able to rotate relative to the vertical support 37.

Turning to figures 6 to 10 and 17. A hollow outer sheath 40 (figure 6 & 7) fits over the and fully encloses therein the hubs 31,31'. The hubs 31 , 31' are attached to the outer sheath by way of 'Jesus' nut/bolt arrangement 45 that extends through and opening 46 in the top of the outer sheath 40 so that both the outer sheath and hubs are able to rotate as one unit. The outer sheath (in respect of two stacked arrangement) has an upper portion 41 and a lower portion 42, where the upper portion 41 corresponds to the upper hub and the lower portion 42. The outer sheath 40 includes an upper circumferential rim 43 and a lower circumferential rim 44. The circumferential rims include fixing holes 48 for attaching one end of spokes 70 (figs 1, 9 & 17). The spokes 70 are arranged in pairs and an end of one spoke 70 of each pair is attached to via fixing hole 48 to the upper circumferential rim 43 and an end of the other spoke is attached to via a fixing hole 48 to the lower circumferential rim 44. The other ends of the spokes of each pair are attached via fixing holes 52 of blade supporting segment 50 (fig 1, 8, 9 & 17). Anumber of segments 50 are joined together to form a circular band that is spaced from via spokes 70 and surround the outer sheath 40 (fig 1, 9 & 17). The spokes are arranged and attached to the segmented band such each pair of spokes is arranged in X configuration as shown in figs 1, 9 & 17 (note not all the number of spokes are shown). It is envisaged that up to at least 20 pairs of spokes will be required. The spokes 70 would consist of three parts, two elongate strands of tensioned wire/rod and an adjustable tensioner whereby two ends of the wire rod are connected to the adjustable tensioner and the two free ends attached to the circumferential rim 43, 44 and segment 50, thus the spokes are able to be tensioned to the desired tension in order to maintain the shape and integrity of the blades 60 (figs 1 & 17) relative to the outer sheath 40. Blades 60 are attached equally spaced apart to the circular band and are shaped like a wing (fig 10) such that as the wind blows the effective and efficient face of the blades 60 are presented so that the blades are able to rotate in a circular direction relative to the outer sheath 40 and in so doing cause the outer sheath 40 to rotate, thus causing the magnetic hubs to rotate relative to the respective radial coiled array to produce electrical power for use.

Figures 14 shows a cross section of a magnetic hub 30 showing magnets 19 in position with Received at IPONZ on 12 December 2011 spacings 19' there between for use in a 3kilowatt version of the wind powered generator.

Figure 15 shows a cross section of a 6 stacked array wind powered generator. The array 20 is surrounded by the magnetic hub 30 which is surrounded by the shroud 40 mounted on plinth 35. Figure 16 shows a similar, but partial view shown in figure 15, however only 2 of the arrays are shown.

Figure 18 shows another variation on attaching the wings 60 to the shroud 40. Instead of using spokes 70 as shown in figures 1, 9 & 18, in figure 18 the spokes are replaced with rods 80 (only one shown) and tensioning cables 81. The rod 80 is fixed/attached at one end to the outer surface of the shroud 40 and the other end of the rod 80 is fixed/attached to the wing 60, preferably at the mid portion of the longitudinal extent of the wing. In order to maintain the wing in the correct position, tensioning cables 81 are attached. The cables 81, preferably at least four per wing are attached at one end to the fixing holes 48 on the rims 43, 44 of the shroud 40 and radiate outward therefrom and are attached to the wing 60 at positions along the wing as shown in figure 18.

Each radial coiled array has a heat sink and four 500 volt bridge rectifier for a sizeable amperage and voltage coming out of one array.

A wind generator with a single radial coiled array and magnetic hub combination produces one kilowatt of power with an excess of 120 -180 volts.

A wind generator with a two radial coiled array and magnetic hub combination produces two kilowatt power with an excess of 280 volts.

A wind generator with a three radial coiled array and magnetic hub combination produces 3 kilowatt of power with an excess of 360 to 390 volts.

The wind generator is designed to have one moving part.

The wind generator is controlled by a PLC where the PLC is adapted to control the voltage or amperage output or control the rotational speed.

The PLC is adapted to control the voltage or amperage by altering the number of phases within each radial coiled array. 16 Received at IPONZ on 12 December 2011 The PLC is programmed to monitor battery state, power usage and wind speed of the generator.

The outer housing and magnetic hub combination spin on a horizontal plane with the blades rotating around the outer housing and magnetic hub combination and the blades aligned vertically.

The outer housing and magnetic hub combination spin on a vertical plane with the blades rotating around the outer housing and magnetic hub combination and the blades aligned horizontally.

The wind generator includes a clutch/braking device, typically electronically operated, to control the rotational speed of the generator.

The wind generator can be mounted on a vertical support or on a horizontal support.

This innovative wind generator differs most other types of wind generator that is it has only one moving part.

The wind generator is able to be upgradable from a 700 watt device to a 1.4 kilowatt device by adding a further radial coiled arrays and magnetic hubs then a 2.8 kilowatt then device 3.5 kilowatt and then finally 5.6 kilowatt with no great difficulty.

By exchanging the magnetic hubs and the addition of further coiled arrays the wind generator can be configured to suit the desired power requirements such that the wind generator can be configured to run in parallel to improve amperage with same voltage or in series to opt for increase voltage and same amperage. This configuration can be carried out as an initial fixed wired system or with the help of PLC. Or common voltage controlled relays. Or alternately the fluid drive generator / wind generator can be configured from the start as a 5.6 kilowatt or greater device and control by PLC as to what configuration it will be depending on the wind conditions.

The combinations are numerous to say the least for example by adding all the deltas together in a radial coiled array can achieve a 14 phase or 28 phase generator.

Each coiled array comes with its own bridge rectifier and heat sink in order to achieve the best voltage and amperage from the radial coiled array. 17 Received at IPONZ on 12 December 2011 The standard single one 700 watt device major components are: • One clutch/braking device electronically operated • One coiled array inclusive of basic rectifier not controlled • Two standard sealed bearings one at base of unit and one in the centre of coiled array • One base • One splined shaft • One PLC or common relay controller • Turbine + blades Operation of basic unit load control can be • Battery/Ups • National grid • Heating under floor type, • Water heating The PLC is programmed to monitor and control battery state, power usage and wind speed of the generator, load requirements, load shedding etc.

If wind speed gets too high and load decreases the generator will normally want to run faster, however the PLC or control relay device will then detect this increase in speed and redirect additional power to either heat-sinks, water heating, under floor heating or dump surplus power on the national grid. The extra load created at this point will slow the generator down thus enabling it to run during higher winds \ Failing this the PLC can operate the electronic clutch to slow down the unit. As a fail-safe the PLC can completely shut the generator down.

The rotor i.e. wings can be made from stainless steel components or suitable plastic materials or any other suitable material.

The outer housing and magnetic hub can be made from plastic materials or any other suitable material.

The wind generators can be installed on top of light poles, or existing houses or other building structures.

In respect of a wind turbine for fluid driven generator, the wind turbine rotates on a horizontal 18 Received at IPONZ on 12 December 2011 plane, with the blades being on the outside of the hub and rim, connected to the rim mounted from the mid section of the blade in a vertical position. So that if viewed the blades connected to the rim would have a portion below the rim and a portion above the rim.

In one embodiment, when viewing the rotor and hub connected to a fluid driven generator and in a vertical position the blades would be in a parallax. In another embodiment, when viewing the rotor and hub connected to a fluid driven generator and in a horizontal position the blades would be as in a common propeller.

In both embodiments the turbine creates rotary motion as wind moves across the surface of the blades. This creates a low pressure area and on the opposite side of the blade a high pressure area. As the two surface areas are of a different size lift is created, as lift is created this overcomes drag and forward motion takes place. As this is repeated over all blades the forward motion results in the turbine rotating, which in turn, turns the magnetic hub inside the shroud. The magnetic hub's motion creates a magnetic flux in the coiled array as the magnets pass over the coils this we measure as and recognise as electricity. The amount of electricity developed depends on how fast the turbine turns,how many coils it has in the array and how many phases are in operation and what configuration they are in.

Advantages a) Cheap to produce at present b) It only has one moving part c) Clean and green uses a renewable resource d) As the device does not create carbon emissions it qualifies for the stamp of approval from the government as a clean green product carbon friendly product e) Affordable for the everyday citizen f) Can be used in standalone applications. g) Can produce low to medium voltage electrical power. h) Can produce high voltage electrical power. i) Interchangeable to suit desired and required power outputs. j) Able to provide low to medium voltage electrical power. k) Able to provide high voltage electrical power.
