Description

31 03 25 The present invention relates to a hydrogen-fuelled gas turbine power system and turbine components, also referred to for the environmentally acceptable production of electrical 5 energy. For example, as suitable for National Grid distribution. Background: Around the world, the most commonly used source of power is fossil fuels. Wherein power is produced in power stations which burn the collected fossil fuels within a furnace, using the 10 heat from the furnace to turn water within a closed system into steam. This steam travels through the closed system wherein it impacts and rotates a turbine. This turbine in turn rotates a generator shaft, allowing the generator to produce power. However, there are problems associated with using these fossil fuel-based power stations, specifically the amount of pollution produced. As the burning of fuels in the furnace produces 15 large amounts of CO2 and other greenhouse gases which are then released into the atmosphere. The fumes from the furnace may also include other pollutants such as sulfur dioxide which when released into the atmosphere produces acid rain. Their furnaces may also produce solid waste in the form of ash and dust which needs to be disposed of. Lastly, the process of gathering the fossil fuels to use in these furnaces can cause further 20 environmental damage. In particular, mining and fracking damage the landscape and can produce more pollutants. Therefore, there is a need to provide a system that can produce power without damaging the environment. To this end, several environmentally friendly, or green, power-generating methods have 25 been developed. These alternative methods include solar power, which gathers energy from sunlight to heat water or provide power through the photoelectric effect, wind power, and wave power, which uses the kinetic energy from the wind, from waves, or from tides to rotate a turbine, which powers a generator as described above. Though these new methods do not produce pollution when in use like the fossil fuel-based 30 systems, these new systems do have their own set of problems. The first problem is that many of these environmentally friendly systems are unreliable, or insufficient as a power source as their ability to provide power is weather dependent. For example, solar panels may not produce sufficient power, if any, on a cloudy day or at night when there is little or no 31 03 25 sunlight. Similarly, the wind and / or wave power systems rely on there being sufficient wind to provide kinetic force to the turbine, so on days where there is no wind these systems may not work, further, during storms or days where there are high winds these systems may need to be shut off to avoid the risk of damaging the system’s turbines. This means that the output 5 of these systems is inconsistent, meaning that as a power source, these systems are unreliable. Further, these new systems often require new infrastructure to operate. As the users would need to manufacture the solar panels or turbines used in each of these new systems. Then these new features would need to be installed at a suitable location, which in the case of 10 wind turbines may be very remote, or in the case of wave turbines the location would need to be on the coast where space is limited. Either way, the outputs of these systems would then need to be coupled to a power grid, which may be difficult if the system is in a remote area. And the further the distance between the power generating system and the consumers using the power, the more energy may be lost through the system, thereby reducing the efficiency 15 of these new systems. All of this new infrastructure would require materials to build and the process of gathering and using such materials would produce a large amount of pollution in itself. The present application is effectively a divisional application of GB 232862.2 by the same inventor but filed within the priority year. 20 Relevant prior art includes WO2010 / 003205A1, AT514480A1, and US2018 / 328216A1. Therefore, there is a need for a new power generating system that not only produces less pollution than the fossil fuel power stations, but is also more reliable than the green power systems that are weather dependent, and preferably would be configured to use existing infrastructure or be able to be configured in any desired location. 25 Summary: The present invention in its various aspects is as set out in the appended claims. The present invention provides an alternative system for generating power, which may adopt the existing infrastructure from fossil fuel power stations to reduce the materials and costs 30 needed to implement the system and ensure that the system is suitably close to the end consumers. The present invention provides . 31 03 25 a power generating system comprising: a hydrogen-fuelled jet (40), wherein the output (42) of the jet (40) is coupled to a hollow channel (50); one or more first rotating members housed within the hollow channel (50) downstream from the jet (40); one or more second rotating members coupled to the one or more first rotating members; wherein the second rotating members are configured to be actuated by the rotation of the one or more first rotating members; one or more generators (30,30’) coupled to a respective second rotating member, wherein the rotations of the second rotating member power the generators (30,30’); wherein the first rotating member comprises a turbine wheel (60) comprising a plurality of turbine blades (62); wherein the wheel (60) is positioned at least partially within the channel (50) such that the rotational axis of the wheel is perpendicular to the elongated length of the channel, and is configured to be rotated by the exhaust flow traveling through the channel (50); and wherein the second rotating member comprises a spindle (70) that extends along the rotational axis of the turbine wheel (60) wherein the spindle (70) of the one or more turbine wheels (60,60’) extends from both sides of the turbine wheel (60,60’), with one or more generators (30,30’) coupled to each side of the spindle (70) wherein the system comprises a plurality of channels (50, 50’), wherein each 5 channel of the plurality of channels comprises a respective hydrogen jet (40,40’) coupled to one end of the channels (50,50’), such that the exhaust from each jet (40,40’) flows through a respective channel of the plurality of channels (50,50’); wherein each of the plurality of channels (50,50’) comprises one or more turbine wheels (60,60’) with each wheel comprising a spindle (70) coupled to one or 10 more generators (30,30’); and wherein the one or more wheel housings (80) are coupled to two or more of the plurality of channels (50,50); with the turbine wheels (60,60’) within the housings (80) positioned such that at least one blade (62) of the wheel extends into each of the two or more channels (50,50’) coupled to the wheels housing (80). 31 03 25 The present invention therefore provides a specific form of hydrogen fuelled power generation and does so in a format, as mentioned in the background, which may be particularly suitable for localised power generation. In this respect it is particularly beneficial that one or more generators are coupled to each side of the spindle. Hence, the spindle from 5 which the power generated by the rotating members is conveyed to the generators for the generation of electrical power can convey that power / energy to a plurality of generators as a balanced mechanical load. This is beneficial as it enables adaptation of the generators without having to take the system off-line, which with hydrogen power and the greater potential for explosion is more safely left in an equilibrium state of operation rather than 10 being stopped / started. Furthermore, one generator may be, for example, configured to supply power into the electrical grid and the other generator, for example may be configured to supply power for localised usage. This enables the two electrical systems to be maintained separately, such as, electrically, on either side of a meter appliance and enables a change of the distribution of the power t output o occur without any actual switching taking 15 place. As mentioned this is useful for hydrogen powered generation as the consistency of operation at a stable, elevated temperature is highly desirable for optimal operation. In a further aspect of the invention the one or more generators are configured to generate electrical power at a different frequency and / or voltage. This is particularly useful were high voltage, such as three-phase output is required alongside a single phase output. It not 20 necessarily being practical to isolate a single phase for, for example localised 240 V operation, as this will give unbalanced load on any three-phase generator generating for example 415 V. Further, having generators on either side of the spindle gives balanced load upon the spindle and again, more stable operation for power where, as maintenance operations 25 typically require stopping the equipment and as mentioned when using hydrogen fueled equipment, stable constant operation is preferable for both efficiency and improved safety. This new power-generating system replaces the furnace and water system used in a fossil fuel power station, with a jet engine, in particular a hydrogen jet. As the name suggests the 30 jet used in the system would be powered by hydrogen which is abundant in the atmosphere and can be easily extracted, it may also be extracted for example through the electrolysis of water. This means that the fuel required in this system can be gathered with less pollution being produced. Further, when hydrogen is burned as fuel the only product produced is 31 03 25 water vapor, meaning the jet would produce far fewer pollutants when compared to the fossil fuel furnace. When in use the output, or exhaust, of the jet would be coupled to a hollow channel, such that the compressed air ejected from the jet is forced down the channel. This compressed air 5 from the jet replaces the steam used in the fossil fuel system, when using existing infrastructure, the hollow channel would be coupled to the channel of the closed water system so that the compressed air impacts the turbine coupled to the generator, thereby turning the generator to produce power. However, the turbine in this new system does not need to be completely closed, as there is no need to prevent the compressed air from 10 escaping once it has been used. This means there is no closed pressurized system as there would be needed when steam is used as in the fossil fuel system, this is preferable as such pressurized systems may become hazardous if the steam system ruptures, which may cause an explosion of force from the steam system, or if the steam within the system was to leak where it may burn personnel or damage nearby equipment. However, in the claimed 15 system such dangers can be avoided by simply releasing the air back into the atmosphere after it has impacted the turbine. It is noted that this system is more reliable than the solar, wind, or wave-based power systems as the system is not weather dependent, needing only hydrogen fuel for the jet and air to be channeled through the jet, to operate. This system can also be implemented in any 20 location, unlike the structures needed for wind or wave power, and can even use the existing infrastructure from a fossil fuel power station, thereby reducing the number of materials and labor needed to implement the claimed system compared to these other alternatives, which also reduces the amount of position produced building the claimed system. It should be noted that, in some cases, the claimed system may be implemented on its own 25 without the need for existing infrastructure from a fossil fuel power station. In such cases, the system would still comprise a hydrogen jet located, such as by being coupled, at the end of a hollow channel, such that the compressed air from the jet is ejected into the channel, and the airflow of the compressed air travels down the channel, downstream from the jet. Wherein the channel would house one or more rotating members, in this case, a rotating member 30 refers to an object or mechanism designed to rotate when actuated, for example, the rotating member may comprise propellors, hollow tubes, or turbine mounted within the hollow channel or the walls of the channel, downstream from the jet. Wherein the rotating members are configured to rotate as the compressed air from the output of the jet passes over the surface of the rotating member. 31 03 25 These rotating members with the channel would be coupled to one or more secondary rotating members. These secondary rotating members may be coupled directly to the first rotating member or coupled via a suitable object such as a belt, chain gears, or flywheels. Regardless of how the second rotating member is coupled to the first rotating member, the 5 secondary rotating member would be configured to be rotated by the first rotating member as it rotates. This allows the energy from the compressed air to be used outside of the hollow channel, via the secondary rotating members. These secondary rotating members would then be coupled to the generator, so that as the member rotates it actuates the generator so that power is produced. 10 In a preferred embodiment of this system, the first rotating member would comprise a turbine wheel and the secondary rotating member comprises a spindle that passes through the center of the turbine wheel. It is preferable that the turbine wheel is positioned such that the direction of the turbine wheel’s rotations is parallel to the direction of the flow from the jet exhaust and the elongated length of the channel extending from the jet exhaust. This would 15 allow a more efficient transfer of energy from the exhaust airflow and the blades of the turbine. The direction of the turbine blade motion would be in the same direction as the exhaust flow, meaning there are no tangential force components leaching energy from the interaction between the gas in the exhaust flow and the turbine wheel blade. It is also noted that with the wheel in this position, the turbine blades can be relatively flat profile, with the 20 end of the blade remote from the wheel being substantially planar, similar to the shape of a paddle, in a plane perpendicular to the exhaust flow. This will allow the maximum amount of contact between the blade and the exhaust flowing through the channel, and as previously mentioned, as the blades are not curved there are no tangential deflections or redirection of the exhaust flow during the impact with the wheel which may reduce the amount of energy 25 being transferred from the exhaust flow to the turbine wheel. This also means that the wheel’s rotation axis, and the spindle that extends along said rotation axis are positioned to be perpendicular to the elongated length of the exhaust channel. This positioning will allow the spindle to extend out of the channel to be coupled directly to a generator, such that the rotation of the spindle drive the generator to produce 30 power. By using this form for the rotating members, the system would allow the generators to be coupled to the sides of the exhaust channel allowing the system to be more compact compared to other options. It is also noted that multiple generators can be attached to a single spindle allowing a more efficient transfer of energy from the spindle to the generators 35 as all the generators would be driven simultaneously. Further, the direct coupling between 31 03 25 the generators and the spindle means that there are no secondary members, belts, or other intermediate moving parts that would reduce the efficiency of the energy transfer between the spindle and the generators. Further, it is noted that the generators can be arranged around the spindle in an array that would provide a more compact design compared to other 5 means of driving multiple generators, which require these intermediate moving parts. Though it is noted that in some cases, the system may include one or more tertiary rotating members, positioned between the spindle and the generator. Wherein the rotation of the spindle turns the tertiary member, and the rotation of the tertiary member drives the generator. It is noted that in general, it would be preferable not to include these members as 10 they would reduce the efficiency of the energy transfer between the spindle and the generator as the tertiary member In a more preferable embodiment, the turbine wheel and spindle would be in a separate housing coupled to a side of the exhaust channel, wherein the coupled sides of the exhaust channel and housing would be open such that at least one blade of the turbine wheel can 15 extend into the exhaust channel, using this system, the turbine wheel may use blades with a larger surface area compared to a system wherein the wheel is housed within the channel, these larger blades would allow for more energy to be transferred to the wheel for a given volume of the exhaust flow through the channel. Additionally, this arrangement of the turbine wheel prevents the exhaust flow from applying force to both sides of the wheel 20 simultaneously, namely the top and bottom of the wheel. When the wheel is within the channel the force on the top of the wheel is counteracted in part by the force in the same direction applied to the bottom of the wheel, whereas the wheel in the housing would only receive force at one end of the wheel thereby allowing the wheel to accelerate to a greater velocity compare to the wheel within the channel that is affected by opposing forces. 25 Regardless of the arrangement chosen for the wheel, another benefit of this system is that depending on the size of the exhaust channel, multiple turbine wheels may be positioned within a single channel, more, specifically, there may be several turbine wheels as described above positioned at different points along the elongated axis of the exhaust channel, it is noted that as the flow of the exhaust from the jet is limited to the channel the flow is capable 30 of rotating multiple wheels simultaneously as it travels down the length of the channel. In some cases, the additional wheels may be positioned at different points around the circumference of the channel, this may be preferable because by positioning the wheels at different positions around the channel’s circumference the blades on each of the wheels would cover a different portion of the channel when looking down the elongated length of the 35 channel, thereby allowing the wheels to capture the flow of the jet exhaust as each point in 31 03 25 the cross-section of the channel, this ensures that more energy is capture from the jet exhaust when compared to a single wheel. The problem with these arrangements with multiple wheels is that as the exhaust gas travel further down the channel, they begin to lose momentum and therefore have less energy to 5 transfer to the turbine wheels. Further, when the exhaust flow passes over each wheel energy is transferred to the blades of the wheel, this result is a decrease in the energy of the exhaust flow causing further losses in the exhaust gas momentum. This loss in momentum means that at a certain point along the length of the channel, there will be insufficient force in the exhaust flow to turn the turbine wheels in the channel. This effect can be overcome by 10 having the wheels positioned at different points on the circumference of the channel, as the offset between the wheels means that exhaust flow that does not contact the upstream wheels may be captured by the downstream wheels allowing the downstream wheels to receive more energy per a given volume of hydrogen jet’s exhaust gas flow. However, even with such off-sets between the wheels there will still a point be a point downstream from the 15 jet where the exhaust flow is insufficient to rotate the turbine wheel. To overcome this effect, the system may comprise two or more channels, wherein the turbine wheels are positioned between the channels, such that the blades of the wheel extend into each channel. In these cases, there would be a hydrogen jet coupled to an end of each of the channels, such that when the exhaust flow from each channel reaches the 20 wheel, they all rotate the wheel in the same direction allowing more force to be applied to the wheel. In these systems when there are multiple wheels, each wheel will be a different distance from each of the hydrogen jets and preferably each wheel will be positioned such that the closest jet to each wheel is a different jet. with such an arrangement we can ensure that each wheel is sufficiently close to at least one jet exhaust such that the flow in the 25 channels can rotate the wheel and generate power. The simplest example of a multi-channel system comprises two parallel channels, with a hydrogen jet positioned at the first end of the first channel and the opposite end of the second channel, such that when the hydrogen jets are active the flow from the exhaust of each jet travels down their respective channel in the opposite direction relative to the flow in 30 the other channel. Then one or more turbine wheels would be positioned in between the channels such that one side of the wheel extends into the first channel and the opposite end of the wheel extend into the second channel. With this arrangement, the flows in each channel rotate the wheels in the same direction thereby increasing the rotational velocity of the wheel compared to a system comprising a single channel. 31 03 25 Further, when the above-mention system includes multiple wheels, the wheels would be positioned along the channels such that the closer the wheel is to one jet, the further that same wheel would be from the other. This results in the force being delivered to each wheel being roughly consistent regardless of the wheel’s position in the channel, as the total force 5 acting on each wheel averages out to be about the same due to the cross-flow caused by the flow in each channel flowing in opposite directions. It is noted that this effect can be achieved with more than two channels, by having a plurality of parallel channels, wherein the flow in each pair of adjacent channels travel in opposite directions, with the plurality of wheels being positioned in between adjacent channels as described above. By using this 10 arrangement, the system ensures that there is sufficient force to drive each of the turbine wheels in the system to produce the maximum amount of power for a given number of hydrogen jets in the system. It is also noted that instead of having a separate hydrogen jet for each of the channels in the system, the claimed system may instead comprise a hydrogen jet coupled to the end of a 15 channel which downstream from the jet separates into multiple channels. This way a single hydrogen jet can be used to supply an exhaust flow to multiple channels. In doing so the wheel in each channel can be positioned closer to the jet thereby reducing the amount of energy loss due to the exhaust moving down the channel. This system would also allow more turbine wheels to be attached to a single jet, due to the larger surface area of the 20 plurality of channels compared to a single channel. However, it is noted that the size of the channels in these cases would be significantly smaller compared to the system where each channel comprises a respective jet. This in turn limits the size and / or number of the wheels and generators that can be used with each channel. Meaning that even though this system would produce more energy compared to a single-channel system, the system would 25 produce less energy compared to the system with a plurality of channels where each channel comprises a respective jet. It is also noted that the various systems described above may maximize the number of generators coupled to each turbine wheel to further increase the system’s power output. More specifically, as the elongated spindle is positioned perpendicular to the elongated 30 length of the channel, there is hypothetically no limit to the size of the spindle that can be used, especially if the turbine wheel is in a separate housing as described above, instead of being positioned within the channel itself. As the user increases the size of the wheel’s spindle there will be a larger surface area for mounting generators. As such the size of the spindle can be increased to increase the number of generators the turbine wheel can drive. 35 It is therefore preferable for the user to use longer wheel spindles so that more generators can be mounted to each of the turbine wheels in the system. 31 03 25 However, it is noted that there is a limit on how much the size of the spindle can be increased. In particular, as the size of the spindle increase so does the spindle’s mass, resulting in the wheel needing more force to accelerate the spindle to a desired rotational velocity. Similarly, each generator mounted to the spindle will produce friction as the spindle 5 is turning, therefore by increasing the number of generators attached to the spindle the amount of friction acting on the spindle increases, further increasing the amount of force needed to drive the spindle. Eventually, the spindle would become too heavy to be driven by the hydrogen jet, or the amount of friction would become too high preventing the wheel from driving the spindle. 10 Therefore, the user must compromise when deciding the size of the spindle and the number of generators attached to each spindle. In particular, the user will determine a suitable number of generators that can be driven by the spindle based on the output of the hydrogen jet being used to drive the turbine wheel. Also, the user may determine a suitable size for the spindle based on the output of the hydrogen jet and the size of the wheel being used to drive 15 the spindle as the size of the wheel would affect the maximum size of the spindle that said wheel my drive when placed into the exhaust flow of the hydrogen jet. It is also noted that the system described above is easily scalable. As most of the examples described above use the claimed system within a power station to provide a large amount of energy to a grid. It may also be possible to scale down the power system to a more mobile 20 system, for example, the system may be scaled down to be used as a backup generator for powering a single building or site, or scaled down even further to be used within a device such as an electric car. In such cases, the system would need to comprise a generator housing, wherein the hollow channel extends through the housing, with a miniature hydrogen jet coupled to the housing at the first end of the channel, with the various members and 25 generators suitably scaled down to fit within the housing surrounding the hollow channel. Using this Jet Generator method, the electric car is now producing electricity to drive the electric motor to drive the car. This replaces the electric car battery thus giving its own set of advantages, such as: -No mining for Cobalt or Lithium to produce the battery, the ‘drive’ battery is not required. 30 -No long charging times (refuelling time will be like petrol stations of today). -No charging points (there is no battery to charge). -No recycling or pollution (from thousands of old car batteries that will occur as they are no longer able to hold their charge). -No fuel Anxiety (as in planning your journey via charging points). 31 03 25 This Jet Generator can be extended to all transport, for Road, Rail, or Sea. By using the systems described above the claimed invention provides an environmentally friendly powergenerating system that produces less pollution compared to fossil fuel power stations and present-day transport. And may adopt the infrastructure of said fossil fuel stations to reduce 5 the pollution and costs of building and installing the system. Further, the claimed system is also more reliable than other environmentally friendly energy solutions, such as solar and wind power. This is because the claimed system is not weather dependent and therefore requires less downtime. Instead, the claim system’s output is only reliant on the amount of hydrogen fuel being supplied to the jet. Further, the claimed system requires less downtime 10 as the units within the system such as the jet, generators and turbine wheels can simply be replaced with a new unit when maintenance checks or repairs are required. Lastly, the claimed system is also scalable allowing the same mechanism to be utilized in a variety of applications beyond only a power station. It is also noted for clarity that in the present invention, the term jet has been used. This may 15 alternatively be described as a gas turbine, hence a jet engine herein is a gas turbine engine. Further, it is noted that the general turbine wheels disclosed above may preferably be in the form of a Pelton wheel, as these wheels comprise the broad paddle-shaped blades required in the disclosed invention. Though it should be noted that Pelton wheel are more commonly used in hydroelectric system where the wheel would be driven by flowing water. 20 For this reason, Pelton wheels are normally formed from steel to make the wheel more ridged as sufficiently strong to support the weight of the water flowing over it. In contrast, in the claim invention the turbine wheels are driven by the gaseous exhaust from the jet, which will be significantly lighter than water due to its lower density. Because of this is would be preferable to for the Pelton wheels of the claimed invention to be formed from a lighter, less 25 dense material than steel, as this would reduce the mass of the wheel and in turn reduce the wheels inertia allow the exhaust flow to move the wheel more easily. For example, the turbine wheels may be formed from a carbon fiber composite, or any other suitably ridged material with a density equal to or less than 2g / cm3. This lower density would allow the exhaust fumes to more easily drive the turbine wheel and thereby produce a more efficient 30 transfer of energy from the exhaust to the generators coupled to the wheel. 31 03 25 Detailed description: The claimed invention is illustrated in reference to the following drawings: Figure 1: depicts a coal furnace power station Figure 2: depicts an example of the claimed system comprising a hydrogen jet connected to 5 a hollow channel containing a turbine wheel. Figure 3: depicts the system of Figure 2 with a generator coupled to the turbine wheel. Figure 4: depicts the system of Figure 2 with a plurality of generators coupled to the turbine wheel. Figure 5: depicts an example of how additional generators can be coupled to a single turbine 10 wheel. Figure 6: depicts an example of the claimed system that uses multiple turbine wheels. Figure 7: depicts an example of the claimed system that uses multiple turbine wheels and multiple channels. Figure 8: depicts the system of Figure 7 with additional turbine wheels. 15 Figure 9: depicts the system of Figure 8 with turbine wheels attached to both sides of the hollow channels Figure 10: depicts the claimed invention comprising a plurality of channels, with each channel comprising a corresponding jet and with a plurality of turbine wheels coupled to the channels. 20 The invention depicted in these figures comprises the following features, it is noted that like features are indicated by like reference numerals: 10 - Coal power system 12 - Coal furnace 25 14 - Closed water system 20 - Power generating turbine 30,30’ - Generator 30A, 30A’ - First generator array 31 03 25 30B, 30B’ - Second generator array 40, 40’ - Hydrogen jet 42 - Jet output 50,50’- Hollow channel 5 60, 60’- Turbine wheel 62 - Turbine wheel blade 70 - Spindle 80,80’ - Turbine wheel housing 90 - Exhaust flow arrow 10 100 - Wheel rotation arrow The present invention will now be described with reference to the figures: Figure 1 depicts an example of a coal power station 10 currently used to generate power. Such systems rely on burning coal or other fossil fuels to generate heat which will in turn heat water within a closed system. More specifically, the system comprises a fuel furnace 12 15 that contains part of a closed water system 14, allowing the heat from the furnace 12 to be transferred to water within the closed water system 14. This water turns into steam which can be channeled through the closed system to a turbine 20. Wherein the steam impacts the turbine blades and turns the turbine 20 which would then turn a generator 30 to generate power. The problem is that these systems generate a lot of greenhouse gases and other 20 pollutants when the fuel is burned, additionally, the mining and fracking used to gather the fuel can damage the environment and produce more pollution including releasing more greenhouse gases into the atmosphere. Therefore, there is a need for a more environmentally friendly alternative. In particular, one which can use existing infrastructure, such as the depicted coal-burning system 10, to reduce the amount of labor and materials 25 needed to form the new system. Figure 2 provides an example of the infrastructure that can be used to convert the existing infrastructure into a more environmentally friendly system for generating power. In particular, the figure depicts a hydrogen jet 40 coupled to a hollow channel 50 such that the exhaust output 42 of the jet 40 ejects the exhaust fumes down the elongated length of the 30 channel as indicated by the arrows 90, thereby creating a gaseous fluid flow down the channel 50. Then a rotating member can be inserted into this exhaust flow such that the exhaust from the jet 40 flows over the member forcing it to rotate as indicated by the arrows 31 03 25 100. This rotating member can then be coupled to the existing generator 30 such that the member drives the generator 30 as it rotates. This part of the system is configured to replace the fuel furnace 12 depicted in Figure 1, and provides a more environmentally friendly alternative as the hydrogen burned within the jet only produces water vapor when burned. 5 Therefore, this system no longer produces hazardous combustion products, such as greenhouse gases like carbon dioxide, or Sulphur dioxide which can produce acid rain when released into the atmosphere. The system would also produce less pollution when gathering the required fuel as hydrogen is abundant in the atmosphere and can be produced through the electrolysis of water, thereby reducing the pollution produced by removing the need to 10 mine the fuel for the power station. It is also noted that the system does not need a pressurized system, such as the pressurized water system 14 depicted in Figure 1. This is because as previously stated it is the exhaust fumes ejected from the hydrogen jet 40 which drive the downstream components of the system, thereby removing the need to generate steam, as required in the fossil fuel system. 15 Further, as the exhaust fumes only comprise air and the water vapor produced from the hydrogen used in the jet 40 which is not at risk of harming the atmosphere, there is no need to store the fumes within a closed system and instead, the exhaust fumes may be released into the atmosphere. This can be achieved by simply allowing the exhaust flow to exit the end of the channel 50 which is remote from the jet engine 40. Additionally, it is noted that 20 pressurized systems can be dangerous to personnel in proximity to the system as any leaks of faults within the structure of the pressurized system 14 may cause steam to be ejected into the surrounding potentially scolding or burning personnel or damaging nearby equipment, or worst a fault in the system may lead to an explosive rupture which may eject shrapnel into the surrounding area. Therefore, the claimed system also provides a safer 25 alternative by removing the need for a pressurized system entirely. Figure 2 depicts an example of the preferred arrangement for the claimed system. In this system, the rotating member is in the form of a turbine wheel 60 wherein the wheel comprises a plurality of turbine blades 62 coupled to a central spindle 70. In use, the turbine wheel 60 is positioned such that the wheel is within or at least partially within the channel 50, 30 such that at least one of the blades 62 are within the path of the exhaust flow through the channel 50. It is noted that in contrast to the turbines depicted in Figure 1, the turbine wheel 60 is positioned such that the wheel is perpendicular to the elongated axis of the channel 50, such that the wheel rotates in a direction that is parallel to the flow of the exhaust fumes within the channel. Note that the typical turbines 20 used in the current system are 35 positioned such that the rotation of the turbine is perpendicular to the direction of the gas flow through the turbine. Due to the positioning of the traditional turbine 20 the blades of 31 03 25 these turbines need to be twisted or facing at an angle to capture and deflect the gas passing through the turbine to allow the turbine 20 to rotate. However, this tangential deflect that occurs when the gas flow impacts the twisted or angle turbine blades would result in some of the energy of the captured gas being lost, as the gas would accelerate in the 5 direction of the deflection effectively leeching some of the energy that could have been transferred to the turbine blade. In comparison, the claimed turbine wheel 60 would comprise a plurality of paddle-like blades 62 which would extend in a direction perpendicular to the surface of the wheel’s spindle 70 and is substantially flat with the plan of the blades 62 being perpendicular to the direction of the gas flow within the channel 50. Note that due to the flat 10 profile of the claimed turbine wheel blades 62 and the facing of the blades 62 on the wheel 60, there is a more efficient transfer of energy from the flowing exhaust gases and the turbine, especially as there are no tangential elements that may leech energy away from the turbine wheel 60. This would allow the turbine within the claimed invention to absorb more energy compared to a single turbine in the typical orientation. 15 It is noted that in some cases the turbine wheel 60 may be housed completely within the channel 50, however, in these cases there is a risk that the force acting on one end of the wheel 60 would be counteracted by the force exerted on the other side of the wheel, therefore, it is preferable to have the wheel 60 to be positioned so that the wheel 60 is only partially within the channel 50. This way the user ensures that there is a net force that can 20 rotate the wheel 60. In these cases where the wheel 60 is not completely housed within the channel 50, there will be an external housing 80 coupled to a side of the channel 50, with the wheel 60 being positioned within the housing such that part of the wheel 60 extends into the channel 50 while maintaining the orientation described above. In the most preferable arrangement, the wheel 60 would be positioned such that half of the wheel extends into the 25 channel 50. This way at least one blade 62 would be completely within the channel 50, this would help to maximize the amount of the exhaust flow that is captured by the wheel blades 62, while also removing any counter rotation caused by the opposite side of the wheel which is being contained within the external housing 80. Figure 3 depicts how a generator 30 can be mounted to the system described above. In this 30 example the spindle 70 of the turbine wheel 60 acts as the generator shaft, which drives the generator 30 as it rotates. It is noted that with this arrangement the rotation of the wheel 60 turns the spindle 70 which then drives the generator, without the need for any additional rotational members which may decrease the energy efficiency of the energy transfer between the wheel 60 and the generator 30. Additionally, this arrangement allows the 35 generator to be coupled to the side of the channel 50. With this arrangement, the claimed system may provide a more compact design compared to the current power-generating 31 03 25 systems as the channel 50 only needs to be as long as the wheel 60, and with the spindle 70 and generator 30 being positioned perpendicular to the channel 50 they can be positioned anywhere along the length of the channel 50. Figure 4 depicts a further example of the claimed system wherein instead of coupling a 5 single generator 30 to the spindle 70 is connected to an array of generators 30. In these cases, multiple generators 30 are coupled to the spindle such that the shaft of the generator contacts the side of the spindle 70 so that as the spindle 70 rotates it rotates the generator shafts driving the generators 30. Using this arrangement multiple generators can be driven simultaneously thereby increasing the system’s power output compared to a system with a 10 single generator 30. Figure 5 depicts a further example of a system containing an array of generators 30. In this case, the spindle 70 extends from the wheel 60 in both directions with generators 30,30’ coupled to each side of the spindle 70. Further as shown in the depicted example, the length of the spindle can be extended to allow further generators to be coupled to the spindle 70. In 15 the depicted example, each side of the spindle 70 features two generator arrays (30A,30’A, 30B,30’B), and it should be noted that the spindle can be extended to allow further generator arrays to be coupled to the spindle 70. Further, though not depicted in these examples, the spindle 70 may be coupled to tertiary members such as belts or chains which couple to further generators that are more generators that are more remote from the spindle 70. As 20 noted above the additional generators 30,30’ would increase the power output of the overall system as all of the generators 30,30’ can be driven simultaneously. However, it is noted that the addition of each generator 30,30’ and any tertiary members would increase the amount of friction acting on the spindle 70. Additionally, the size of the spindle 70 would need to be increased to accommodate the additional generators 30,30’ 25 further increasing the amount of friction on the spindle 70. Therefore, there needs to be a compromise between the amount of power the system generates and the number of generators 30,30’ coupled to the turbine wheel, this decision would be based on different factors such as the velocity of the exhaust exiting the jet and the size of the turbine wheel. In general, it is probably best to have only one array of generators 30,30’ on each side of the 30 spindle to reduce the amount of friction acting on the spindle 70, while producing a sufficiently large amount of power from the turbine wheel 60. Figure 6 depicts another example of the claimed system that uses multiple generators 30,30’ to produce more power, however in this example the system comprises an additional turbine wheel 60’ positioned downstream from the first turbine wheel 60. It is noted that each wheel 35 within the channel may have one or more generators 30,30’ coupled to the wheels’ 31 03 25 respective spindle 70. As with the previous example, this arrangement increases the amount of power produced by the claimed system by having multiple generators 30.30’ being driven simultaneously. However, the system with multiple wheels 60,60’ helps to improve the efficiency of the system compared to the previous example with a single wheel 60 as there 5 would be less friction acting on each wheel 60,60 due to each wheel having few generators 30,30’ to drive and also having a smaller spindle 70. In the depicted example each of the turbine wheels 60,60’ are housed within their respective housing 80 coupled to the channel 50 as described above. However, in some cases, each of the turbine wheels 60,60’ in a plurality of turbine wheels 60,60’ may be placed within a single 10 housing 80. Though it is noted that it is preferable to have each wheel 60,60’ within a respective housing 80. This is because the wall of the housing channel forms a channel around the wheel, that helps to direct some of the exhaust flow from the channel 50 around the wheel thereby increasing the force acting on the wheel blades 62. However, when the housing contains multiple wheels 60.60’ there is no longer a wall surrounding the wheel that 15 can direct the fumes and therefore there would be a loss of force acting on the turbine wheels 60,60’. One problem with the arrangement shown in Figure 6, is that the wheels 60,60’ in the channel 50 are adjacent such that the first wheel 60 is directly in front of the second wheel 62. This means that when the system is in use the first wheel 60 may block or partially block 20 the exhaust flow from reaching the downstream wheel 60’ thereby reducing the amount of force exerted on the second wheel, this problem would be made worst by introducing additional wheels into the channel. However, this problem may be addressed by offsetting the wheels 60,60’ at different angles around the circumference of the channel 50. This way adjacent wheels 60,60’ do not obstruct each other, thereby allowing each wheel to receive 25 more of the exhaust flow increasing the force acting on the wheel blades 62 thereby increasing the amount of energy that is transferred to the spindles 70 allowing the system to generate more power. It is also noted that when the system comprises multiple wheels 60,60’ the wheels that are placed further downstream may not receive sufficient flow to power the generators 30,30’ 30 attached to it. More specifically as the exhaust fumes from the jet 40 travel down the channel 50, they will start to lose energy and eventually, the fumes will have insufficient energy to turn the turbine wheel 60’ even if the wheel is off-set relative to the upstream wheels as described above. One way of addressing this issue would be to reduce the distance between jet 40 and the turbine wheels 60,60’. One way to achieve this would be to have the wheel 35 blades overlap like the teeth of interlocking gears, however, in such a system the wheels will 31 03 25 likely obstruct each other as they try to turn. Another solution would be to have the channel 50 divided into several smaller channels, wherein each of the smaller channels comprise one of the plurality of wheels 60,60’ thereby allowing each wheel to be placed equidistance from the jet 40 and without the wheels 60,60’ obstructing one another. However, it is noted 5 that each wheel would only receive a portion of the overall exhaust ejected from the jet which may reduce the amount of power each wheel generates, and may therefore reduce the overall power produced by the system. The preferred solution to this problem is illustrated in Figure 7. In this system, there are two parallel channels 50,50’ each channel comprising a hydrogen jet 40,40’ coupled to one end 10 of the channel such that the exhaust ejected from the jets 40,40’ travel down their respective channel 50,50’. In this system, the turbine wheels 60,60’ are located in between the channels such that the blades 62,62’ of the wheels 60,60’ extend into each of the channels 50.50’. the key aspect of this arrangement is that the exhaust flow through each of the channels is in different directions such that the flow from the channels creates a cross 15 current over the wheels 60,60’. In this case, the term cross-current is referring to how the flow in each of the channels rotates the turbine wheel 60,60’ in the same direction, clockwise or anti-clockwise, despite the flows being in different directions. In the case of the depicted example as there are two parallel channels, the exhaust flow in the channels 50,50’ are in opposite directions as indicated by the arrows thereby creating the cross-current over each 20 of the turbine wheels 60,60’. It is noted that this cross-current helps to average the amount of force each turbine wheel 60,60’ receives from the jets coupled to the system, as the distance between the turbine wheels 60,60’ and jets 40,40’ would average over the length of the channels 50,50’ for the turbine wheel closes to the first jet 40 would be the furthest from the other jet 40’ and vice versa. By using this arrangement for the system, the velocity of 25 each wheel 60,60’ would be higher allowing each wheel 60,60’ to drive more generators 30,30’ and thereby produce more power. It is noted that even though the depicted example in Figure 7 comprises only two channels 50,50’ and two turbine wheels 60,60’, it is noted that the same arrangement may comprise additional wheels and / or additional channels, so long as each turbine wheel extends into at 30 least two of the channels. For example, Figure 8 depicts an example of this arrangement with four turbine wheels coupled to a pair of parallel channels 50,50’. Other arrangements may include a plurality of parallel channels with turbine wheels coupled between each pair of channels, in some cases the system may comprise two channels that divide into a plurality of smaller channels, with the smaller channels forming parallel pairs of channels like those 35 depicted in Figure 7 and 8, with the turbine wheels positioned in between pairs of channels. Another arrangement would comprise a plurality of channels forming a regular shape such 31 03 25 that the exhaust flow from the jets flows around the perimeter of the shape with the turbine wheels positioned at the corners of this shape to receive the flow from two jets simultaneously. Of these options, the plurality of parallel channels would be preferable as this arrangement can be more compact for a given number of turbine wheels. Further, 5 having a plurality of smaller channels coupled to a single jet reduces the amount of hydrogen fuel that needs to be used to operate the system, while the cross current in the channels helps to maximize the system’s power output. Figure 9 depicts another example of the claimed invention which utilizes a pair of parallel channels 50,50’ each comprising a respective hydrogen jet 40,40’. In this example the 10 system utilizes more turbine wheels 60, by hove wheel housing 80 attached to both sides of each channel 50,50’. With this arrangement the same two channel 50,50’ depicted in the previous figures may now drive more turbine wheels 60,60’simultaneously. As each of the wheels 60 is coupled to a respective array of generators 30,30’ this arrangement would increase the overall power produced when compared to the system from the previous 15 figures. However, it should be noted that only the turbine wheels in between the two channels 50,50’ would benefit from the cross-current flow described above. This means that the outer turbine wheels, refereeing to the wheels that are only attached to the outer edge of a single channel would have a lower driving force compared to the center wheels, and therefore would likely produce less power. Though it should be noted that these outer 20 wheels may be offset relative to the central wheels, such that the outer wheels are nonparallel to the central wheels, this off-set ensures that there is a lower area of overlap between the blades 62 of each wheel, thereby allowing each of the turbine wheels 60,60’ to receive more of the exhaust flow within the channel thereby increasing the driving force acting on each wheel. 25 Figure 10 depicts an example of the claimed system that uses a plurality of parallel channels 50, similar to the previous examples each channel comprises a respective hydrogen jet 40 couple to one end of the channel. Note that the channels are arranged so that the jet 40 is at the opposite end of the channel 50 relative to the adjacent channels, thereby creating a cross-current between the channels as the exhaust flow will be in opposite directions in 30 adjacent channels. As with Figure 9, the system of Figure 10 comprises turbine wheels 60 coupled to both sides of each channel, thereby increasing the number of turbine wheels 60 and in turn increasing the number of generators 30 the system can drive simultaneously to increase the systems output. However, by utilizing more channels the system is able to produce a cross-current flow over a greater number of turbine wheels 60, as more wheels 35 can be placed in between the parallel channels, and therefore can produce a higher average driving force across all of the turbine wheels 60 in the system, which in turn increase the 31 03 25 average energy output of the power system, it is noted that this system may still comprise one or more outer turbine wheels which are only coupled to a single channel 50, as with the previous example these outer turbines may be coupled to the channel at an off-set compared to the central channel to reduce the amount of obstruction between the turbine 5 wheels within the same channel. It should also be noted that the arrangement shown in Figure 10 may be extended to include more channels 50 and more turbine wheels 60, however, the inclusion of more channels would require the system to use more jets 40, and in turn would use a greater amount of fuel therefore, the user would need to come to a compromise in regards to the optimum number of channels 50 and in turn the maximum 10 number of turbine wheels 60 that can be driven for a certain amount of hydrogen fuel. By using the systems described above the claimed invention provides an environmentally friendly power generating system, wherein the system uses the output from the hydrogen-fuelled jet 40 to rotate a generator 30. It is noted that the burning of hydrogen within the jet produces fewer pollutants compared to the burning of fossil fuels. Further, this system may 15 adopt existing power station turbines 20 and generators 30 coupled to the jet output 42 to reduce the costs and materials needed to implement these systems. Instead, the user may use the above-mentioned turbine wheels 60,60’ to transfer power from the jet output 42 to the generators 30,30’, as these systems are more easily scalable to allow the user to produce a generator that is best suited for the user’s needs. 20 This new system not only reduces the amount of pollution produced during production, and from the gathering and burning of fuel, but the claimed system is also more reliable than other environmentally friendly energy solutions, such as solar and wind power. This is because the claimed system is not weather dependent and therefore requires less downtime. Instead, the claim system’s output is only reliant on the amount of hydrogen fuel 25 being supplied to the jet 40. Further, the claimed system requires less downtime as the units within the system such as the jet 40 and turbine wheels 60,60’ can simply be replaced with a new unit when maintenance checks or repairs are required.
