Vertical Axis Wind Turbines


Mother nature spoils mankind with energy in abundance. The energy is not to be found concentrated in one spot or in just one of Platon's elements where it could be collected easily. Instead energy is rather equally distributed on the globe inherent in the radiation of the sun, in the kinetic energy of the wind and in the flow of water. Mankind has to reinvent techniques which have been used in the earliest stage of civilization. We all have to become hunters and collectors again - energy will be subject to collecting and hunting in our times. It will be one challenge to collect it in the planes and in the mountains as well as on the coasts and in the open seas, another challenge will be to store it, to save it and to use it wisely. Skills and creativity of the hunter will be needed for collecting it with new methods affording a minimum of effort. Methods and devices will resemble giant fish traps, when rotor blades are connected among each other to form a giant net structure like with the RES - Giga Tube, they may be similar to giant ring shaped traps like with the RES - Giga Wheel, or they may featuring a giant blade like with the RES - Mega Wheel. All of these devices and structures are rooted in the earliest stages of civilization when spears already where aerodynamically formed to fly and nets were manufactured to catch the prey and circles of stone have been erected to get hold on seasonal change, resembling contemporary circular structures for mirrors concentrating sunlight on one spot on a central tower resembling a menhir.

#towhomitmayconcern : Tensegrety Structure for a Wind Turbine #resgyroturbine German patent granted : https://lnkd.in/ea2iajMR https://lnkd.in/eNYWFN2R International pct application : Examiner's report available. #asktheinventor Here at the RES Institute, the patent examiner's report is available for E-wing, the electric adjustable rotor blade. Only documents classified with A could have been found as relevant state of the art. Should you be interested to learn more about this invention, please get in touch. The embodiment example shown here features a huge wheel being rotated by the power of wind. "Winds are drafted and not blown" is what R. Buckminster Fuller stated in 1946 and he was absolutely right in this different and prospective perspective of describing the phenomena called wind. Today we know that the wind is a complex three dimensional event, driven by pressure differences in the atmosphere and effects caused by the rotation of the earth itself. Therefore the current model to make use of the gigantic amount of kinetic energy inherent in the wind, by cutting out a flow column out of the atmosphere, that aims at the rotor plane of a wind turbine and will be slowed down there by three rotating rotor blades capable to convert up to 49%, according to the Betz law, of the winds kinetic energy into rotation is only one approach to convert the linear fraction of the flow into rotational energy. There are others. One of the outstanding advantages of a vertical axis wind turbine is the fact that the rotor does not have to be adjusted perpendicular to the wind. A vertical axis wind turbine that uses asymmetrical wing profiles for the rotor blades closes the efficiency gap in comparison to a state of the art wind turbine with a horizontal axis of rotation. Each of the wind turbines shown here, in front of and behind of the Oeresund bridge are twice effective by harvesting the winds energy in the windward half as well as in the leeward half of the rotors orbit. The turbine has a diameter of 300 meters. The middle sections of the three part rotor blades are rigidly connected to the upper and lower part of the outer compression ring of a spoked wheel stabilized by steel cables in a radial arrangement. The compression ring is also used as a walkable maintenance corridor giving access to the rotor profiles allowing inspection and maintenance. The middle part of the rotor blade is cantilevered from the outer compression ring 50 meters up and 50m down. #OffshoreWind #OnshoreWind #EnergyTransition #EnergySecurity #EnergyIndependence #EnergyPolicy #GreenEnergy #RenewableEnergy #WindEnergy #ClimateSolution #OffshoreWind #OnshoreWind #EnergyTransition #EnergySecurity #EnergyIndependence #EnergyPolicy #GreenEnergy #RenewableEnergy #WindEnergy #ClimateSolution #offshore #asktheinventor #reswindpower #windenergy #ewing #resblade #resgyroturbine www.res-institute.com

RES - Gyro Turbine 3

Res - Gyro Turbine saves resources by lightweight construction. https://lnkd.in/eaMmSeNB #resgyroturbine #resgigatube #resdoubleaction While the load bearing parts of a conventional wind turbine with a horizontal axis of rotation are subjected to continuous bending loads, the gyro turbine with a vertical axis of rotation, presented here, has components that are predominantly subjected to tensile and compressive forces. The fact that the center wing segment of the three-part rotor blade is simultaneously part of the load bearing structure allows to build a lightweight rotor basket, made up of compression and tension members held in place by circumferentially under-spanned ring beams. The motor-generator is integrated in a buoy with a counter weight at its lower end. Under water a counter rotating water turbine delivers extra energy and enhances the hydrodynamic stability of this dual effective offshore installation. #windturbine #offshore #asktheinventor #reswindpower #makeitfloat #windenergy #windturbine #offshore #withhydropower #asktheinventor #reswindpower #youcangetitifyoureallywant #resbigbuy

#towhomitmayconcern : Two at a time ! #resbigbuy #resgyroturbine German patent granted : https://lnkd.in/ea2iajMR https://lnkd.in/eRwkSCfG International pct application : Examiner's report available. #asktheinventor This novel floating Gyro Turbine uses the mass inertia caused by gyro forces to stabilize the turbine around the vertical axis of rotation. Coaxial and concentric to the axis of rotation, the hub of a horizontal spoked wheel is connected seventy meters above sea level to a rod-shaped buoy, the lower end of which forms a ballast body. The clockwise rotating upper rotor has a diameter of 300 meters and is conceived as a spoked wheel with an outer rim. A total of 10 rotor blades are arranged parallel to the axis of rotation and are cantilevered from the rim on both sides fifty meters upward and downward. Supporting and tension cables stabilize the rotor as radial spokes and, together with the hub and rim, form a lightweight structure that meets the Buckminster Fuller tensegrity structure criteria. The lower, counter clockwise rotating rotor is conceived as a water turbine with a smaller diameter to compensate precession of the upper gyro. The water turbine is driven by tidal current or by flowing water. The peak power of both turbines sums up to more than 50 MW, so that one buoy can replace seven of today's most powerful floating offshore wind turbines. Also much less material is needed to build this structure, which drastically can lower production costs for electricity. #makeitfloat #windenergy #windturbine #offshore #withhydropower #asktheinventor #reswindpower #youcangetitifyoureallywant #resship www.res-institute.com

#towhomitmayconcern : State of the art turbine compared to a new design. #resgyroturbine https://lnkd.in/e48pxC-Y https://lnkd.in/eVcSpURp #resblade PCT application published with research report ! https://lnkd.in/et9qwc6S Imagine a wind turbine with an inflow area of about 14000 square meters, that at wind speeds up to 12m/s delivers the same amount of electrical energy with half the structural weight of the best conventional 7 MW wind turbine and on top of this, at wind speeds above 12 m/s, when the conventional technique already requires stall regulation, delivers doubled to tripled power output in comparison. Yes, this wind turbine exists as a design: #reswindcolumn. Half the weight - this also means a drastic reduction in electricity generation costs ! The wind column is made of a lightweight steel structure that can be easily assembled, disassembled and recycled. Here just some advantages of the design associated with the structure : Instead of a mast, a very stiff, huge cylinder, built as an airy lattice shell structure, absorbs the entire bending moment. The cylinder has transverse stiffeners made of circumferentially sub-spanned compression rings, so that the cylinder acts like a giant bamboo, as it were, to form a tube structure that is stiff in bending, shear and torsion. The central segment of the three-part rotor blade is designed as a compression bar within the predominantly axially loaded parts of the supporting structure. Electrical actuators are integrated in the central part of the rotor blade, which cause the alignment of the asymmetrically profiled rotor blades to the leeward side of the respective wind direction, whereby a diameter with turning points can be aligned perpendicular to the respective wind direction. The change of the suction side on the rotor blades takes a while and is very helpful to reduce stress peaks caused by abrupt load changes on a conventional Darrieus rotor. There is so much kinetic energy in our gaseous atmosphere that it is easily sufficient to organize growth through regenerative energy. The entire wind energy industry is ripe for a mutational leap ... #asktheinventor #resgigatube #onshorewind #1for10 #windindustry #greenenergy #windenergy #windturbines #enerytransition #reswindpower

RES - GigaTube : Showdown on the Hudson River off Jersey #reswindcolumn PCT application published with research report ! https://lnkd.in/et9qwc6S https://lnkd.in/dmez_w_3 https://lnkd.in/eVcSpURp #resgigatube Would you believe that the wind column on the left requires only half the weight to achieve the same power than the conventional wind wheel on the right at wind speeds up to 12 m/s and can double to triple the power at wind speeds > 12 m/s? #asktheinventor Despite the all-steel construction, the wind column has less than half the design weight of a conventional 7 MW horizontal wind turbine. While the HAWT already has to be down-regulated at wind speeds of more than 12 m/s, the wind column can be operated without regulation at wind speeds of up to 15 m/s and beyond. Especially for offshore turbines, which are often exposed to strong winds, the electrical yield in this range can be doubled or tripled compared to a conventional HAWT. This is possible because the optimum performance of the VAWT is already achieved at a resulting inflow that is "only" three times the wind speed. The center segment of the three-part rotor blade #resblade is designed as a rod-shaped support element of the cylindrical lattice shell structure, while the nose segment and the trailing edge segment of the rotor blade can be adjusted by a maximum of 9 degrees relative to the center segment, wherein the suction side of the rotor blade periodically changes from the inner side of the orbit to the outer side of the orbit and vice versa, at a diameter alignable perpendicular to the respective wind direction with two turning points to align the asymmetrically profiled rotor blades in both halves of the orbit to the leeward side. The rotor blade is divided into longitudinal sections and has integrated actuators that have a setting and holding function in the respective longitudinal sections. The design of a cable-stayed lattice shell is scalable and can be made both smaller and larger than the 200 m tower shown here. Technical specifications : - Incident flow area 14,000 sqm - 8 rotor blades 880 t (550kg/m) - 8 rings 238 t - Tensioning ropes 400 t - Generator 300 t - Nacelle 1.216 t - Total weight 3,004 t

RES - Gyro Turbine 8

The RES GigaTube project challenges conventional turbine designs. A closer look at the advantages should convince you of the concepts superiority. The turbine shown here is slightly taller than the conventional ENERCON E126 turbine, which is one of the best HAWTs in terms of efficiency and design. The VAWT GigaTube shown on the left, with a height of 235 metres and a diameter of 70 metres, has a much better power-to-weight ratio of 360 tons/MW than the ENERCON E126 of 933 tons/MW, which speaks for itself. The Gigatube design uses variable asymmetric profiles that provide up to 30% more lift than a Darrieus rotor with symmetric profiles. Structurally, all load-bearing elements are subject to either tensile or compressive forces. However, at high speeds where lambda reaches a factor of 5, centrifugal forces must be carefully monitored. Radial spokes in the cavity between the mast and rotor divide the cavity into relatively short sections. In addition, the leeward blades are connected to the windward blades. At wind speeds above 12 m/s the centrifugal force will outweigh the lift created by the asymmetric profiles in both semicircular orbits. For this and other reasons, this turbine can be built much more economically than the reference turbine on the right. #resgigatube #windenergy #resblade #resewing #reswindpower #resactuator #offshorewind #windindustry #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #weldedsteel #steelmoduls #magneticlevitation #steelperformance #excellence from #theländ www.res-institute.com

The wind of change is blowing across the Baltic Sea. The four rotor blades of this elegant turbine are designed with a hyperbolic curvature. The rotor diameter is 200 metres at the top of the turbine and only 100 metres at the bottom. This allows the lambda value to be kept constant, resulting in twice the inflow speed at the top compared to half the speed at the bottom of the rotor. Raised 80 metres above sea level, the turbine will have a total height of 600 metres and will deliver 52.4 MW at a wind speed of 15 m/s. In addition, the VAWT's lightweight structure has a power-to-weight ratio of only 343 tonnes per MW.

RES - Giga Tube 1

We are arriving on the 25th of September in the year 2030 in front of the Öresund bridge. A new type of wind turbine is turning around to produce electricity in quantities which ten years ago were estimated not to be possible. The rising demand for clean energy had been a propellant to convert more and more wind energy with the RES - Giga tube at lower cost. How could this mutation leap in the conversion of wind energy happen? Unprejudiced SURVEY of wind turbines, state of the art in the year 2020 and also present in the GIF revealed that three quarters of the structural mass are serving the purpose to install a generator at 140 meters above sea level while the rotor accounts only about one quarter to the total mass of the turbine. At the time development of a new kind of wind turbine already had begun and on the 25th of September 2020 a new design saw the light of the day for the first time. From than on the success of the RES - Giga tube was worldwide. Later on it has been acknowledged that the fusion of the turbines load bearing structure with the rotor had been a very good idea. Radically simplifying the blueprint for a wind turbine the load bearing structure now almost entirely was made up of a multitude of rotor blades connected among each other to form a rotational hyperbolic grid shell structure. Twenty meters above sea level the generator is integrated in a ring shaped base. The rotor blades of the RES - Giga Tube wind turbine change their orientation to the orbit at each nodal joint of the grid shell structure. Therefore it was possible to reduce the overturning moment at the base substantially.


RES - Giga Tube 2

Offshore on the North Sea the Res-Giga Tube with flipped over rotor blades can convert kinetic energy of wind into electricity up to 50 MW and more per unit. The Res-Giga Tube is approximately 480 meters high and has a diameter of about 200 meters at its base. The asymmetric profiled rotor blades are regularly flipped over at nodal connectors of the grid shell structure, to change their suction side from the outside to he inside of the orbit. Lambda reaches up to five times the wind speed, allowing the suction forces resulting from uplift, - which by the way is one third higher in comparison to a symmetric profile - to be balanced between the leeward half and the wind ward half of the turbine's orbit and vice versa. One revolution of the giant tube lasts more than a minute which is important for its impact on the ecosystem as well as for its visible impression. The structure of the Giga Tube is a hyperbolic grid shell with rigid connections between the rotor blades.

#towhomitmayconcern: RES-GigaTube spinning in Cape Town https://lnkd.in/dMPX8i5 The supporting structure of the turbine consists of a central mast supporting a series of nozzles connected to the rotor formed by a cable net structure supporting variable rotor blades. These blades have a pivoting leading edge and a pivoting trailing edge connected to a rigid central section supported by the cable net. The rotor itself is divided into a windward and a leeward half. The blades themselves are variable, consisting of a rigid central section and pivoting nose and tail sections, which are either pneumatically or electrically actuated. Sensor-controlled, one diameter of the wind turbine is always oriented perpendicular to the prevailing wind direction, so that the suction side of the rotor blades faces inwards in the windward rotation and outwards in the leeward rotation. When the lambda reaches a value greater than 2, centrifugal forces override the lift generated by the rotor blades. The answer to this problem, which increases by a lambda factor up to 5, is the concave surface of the hyperbolic prestressed cable net. Spoked wheels in the void between the mast and the rotor will transfer the loads from the leeward to the windward side. In this way, the lateral force acting on the mast can be reduced. This type of design far outperforms any other type of wind turbine in its ability to ration power. #reswindpower #resgigatube #resblade #reswindpower #resactuator #offshorewind #windindustry #greenenergy #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #steelcabels #weldedsteel #steelmoduls #magneticlevitation #steelperformance #sustainable www.res-institute.com

RES - Giga Tube, Osaka Bay
#towhomitmayconcern : Pacific Wind at Oasaka Bay #resgigatube #respentagon PCT application published with examiners report : https://lnkd.in/et9qwc6S Patent granted in Germany : https://lnkd.in/eVcSpURp https://lnkd.in/e9Jzkm5W Listen mariners, when it comes to convert the energy of the wind, it is much better to do so by sailing than to ride a merry-go-round! Three of them giants are revolving in Osaka bay just in front of the Akashi peninsula. In the background we see the Akashi Kaikyo suspension bridge. The rotor of each VAWT has a diameter of 240 meters and is 630 meters tall, covering an inflow area of about 151.000 square meters. At wind speeds of 12 m/s, just one GigaTube will deliver 80 MW, and even more at wind speeds of 15 m/s, when the conventional technique already requires stall regulation, continues to convert energy up to 155 MW and beyond. The total weight of the steel construction will sum up to about 20.000 t resulting in a power to weight ratio of 250 t per MW. This is four times less than the power to weight ratio of a conventional 7 MW wind turbine. Lightweight construction with steel not only cuts down construction costs effectively , due to a modular building system, that easily can be assembled and disassembled as well as it can be completely recycled, it also leads to a drastic reduction in electricity production costs which is crucial for success in the necessary transformation process from fossil based to green energy production. #osaka #bayarea #japan #pacific #windenergy #resblade #reswindpower #resactuator #offshorewind #windindustry #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #weldedsteel #steelmoduls #magneticlevitation #steelperformance #respentagon #stuttgart #uni #sailing #sailor #mariner www.res-institute.com

RES - Giga Tube, Queen of the Baltic Sea
#towhomitmayconcern : Patent granted for the Queen of the Baltic Sea. PCT application published with examiner report ! https://lnkd.in/et9qwc6S Listen mariners, when it comes to convert the energy of the wind, it is much better to do so by sailing than to ride a merry-go-round ! Imagine a wind turbine with an inflow area of about 151.000 square meters, that at wind speeds of 15m/s delivers up to 155 MW and on top of this, at wind speeds above 15 m/s, when the conventional technique already is in stall position continues to deliver even more energy. Yes, this wind turbine exists as a design: #respentagon. Less weight - that also means a drastic reduction in electricity generation costs ! The wind turbine is made of a lightweight steel structure that can be easily assembled, disassembled and recycled. Here just some advantages of the design associated with the structure : Instead of a mast, a very stiff, huge cylinder, built as an airy lattice shell structure, absorbs the entire bending moment. The cylinder has transverse stiffeners made of circumferentially sub-spanned compression rings, so that the cylinder acts like a giant bamboo, as it were, to form a tube structure that is stiff in bending, shear and torsion. The central segment of the three-part rotor blade is a vertical tower housing an elevator shaft and a staircase, giving access to electrical actuators for the swivable and non load bearing leading- and trailing edge segments of the rotor blade, throughout the entire length of each of the five towers. In a regular spacing the five towers are interconnected by eight circular ring beams, that together with a vertical cross bracing make up the airy grid shell structure of the giant rotor. The suction side of the rotor blade is changed always perpendicular to the respective direction of the wind by vertically regular spaced actuators in such way that the suction side of the asymmetric wing profile is oriented leewards, whereby a diameter with turning points can be aligned perpendicular to the respective wind direction. The change of the suction side on the rotor blades takes a while and is very helpful to reduce stress peaks caused by abrupt load changes, which beside the poor performance are a major disadvantage of a conventional Darrieus rotor. There is so much kinetic energy in our gaseous atmosphere that it is easily sufficient to organize growth through regenerative energy. The entire wind energy industry is ripe for a mutational leap. https://lnkd.in/eVcSpURp #resgigatube #resblade #reswindpower #resactuator #offshorewind #windindustry #greenenergy #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #steelcabels #weldedsteel #steelmoduls #magneticlevitation #steelperformance #sustainable #sailing #sailor #mariner www.res-institute.com

RES - Giga Tube, Structural System
#towhomitmayconcern : Patent granted. PCT application published with examiner report ! https://lnkd.in/et9qwc6S #isaset2024 : Monday March 18th - Presentation of #respentagon, a VAWT that will deliver 80 MW. https://lnkd.in/dGUwqGx When it comes to converting the energy of the wind, it is much better to sail than to ride a merry-go-round! The video shows the red, load-bearing central segment of just one of the five three-part rotor blades. Similar to a sailing yacht, the rotor blade rotates around the rotor's axis of rotation and completes a turn of its suction side with an adjustable diameter perpendicular to the wind direction. The 18 m long and 3 m thick profile is temporarily symmetrical. The load-bearing central steel segment of the blade houses a staircase, an elevator shaft and electric actuators designed with a step-lock gearbox to shift the suction side of the rotor blade. The VAWT's rotor is 240 metres in diameter, 630 metres high and covers an intake area of approximately 151,000 square metres. A single GigaTube will deliver 80 MW at wind speeds of 12 m/s, and up to 155 MW and more at 15 m/s, where conventional technology requires pitch control. The total weight of the steel structure will be around 20,000 tonnes, resulting in a power-to-weight ratio of 250 tonnes per MW. This is four times less than the power-to-weight ratio of a conventional 7 MW wind turbine. Lightweight steel construction not only reduces construction costs through a modular building system that can be easily assembled, disassembled and fully recycled, but also leads to a dramatic reduction in electricity generation costs, which is critical to the success of the necessary transition from fossil to green energy generation. #respentagon #reswindpower #resgigatube #resblade #reswindpower #resactuator #offshorewind #windindustry #greenenergy #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #steelcabels #weldedsteel #steelmoduls #magneticlevitation #steelperformance #sustainable #sailing #sailor #mariner www.res-institute.com

RES - Giga Tube
#towhomitmayconcern : www.youtube.com/watch?v=0M55ufMdpSk The RES GigaTube project challenges conventional turbine designs. A closer look at the advantages should convince you of the concepts superiority. The turbine shown here is slightly taller than the conventional ENERCON E126 turbine, which is one of the best HAWTs in terms of efficiency and design. The VAWT GigaTube shown on the left, with a height of 235 metres and a diameter of 70 metres, has a much better power-to-weight ratio of 360 tons/MW than the ENERCON E126 of 933 tons/MW, which speaks for itself. The Gigatube design uses variable asymmetric profiles that provide up to 30% more lift than a Darrieus rotor with symmetric profiles. Structurally, all load-bearing elements are subject to either tensile or compressive forces. However, at high speeds where lambda reaches a factor of 5, centrifugal forces must be carefully monitored. Radial spokes in the cavity between the mast and rotor divide the cavity into relatively short sections. In addition, the leeward blades are connected to the windward blades. At wind speeds above 12 m/s the centrifugal force will outweigh the lift created by the asymmetric profiles in both semicircular orbits. For this and other reasons, this turbine can be built much more economically than the reference turbine on the right. #resgigatube #windenergy #resblade #resewing #reswindpower #resactuator #offshorewind #windindustry #windenergy #windturbines #enerytransition #energyabundance #steel #steelconstruction #elektromagnets #structuralsteel #weldedsteel #steelmoduls #magneticlevitation #steelperformance #excellence from #theländ www.res-institute.com
