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.

RES - Big Wheel 1

RES-Big Wheel : Something big from #theländ reaches out to the Pacific. #resbigwheel https://lnkd.in/emx99Trm has three-part rotor blades #resblade. This big wheel is not intended to spin your wheels, but on the contrary your full attention will be asked to understand its specific advantages. The big wheel can be built with diameters which lay beyond the diameters of state of the art wind turbines. A lightweight structure is used for the rotor, consisting of an outer compression ring, a nozzle and V-shaped tension cables arranged in radial order. The rotor blades themselves lay in a rotor plane and are cantilevered from the wheels outer compression ring to the outer side as well as to the inside. A rotor blade is twisted in itself and consists of a plurality of straight longitudinal sections in which the nose segment and the leading segment are adjustable in a way to either have a positive or a negative angle of incidence respective to the incoming flow. In other words: The suction side of the asymmetric wing profile can be switched from the leeward orientation to the windward orientation. Supposed, the suction side of every second or every third rotor blade is oriented to the windward side, the effect will be not only to have a gradually adjustable means to slow down the rotation of the wheel, but also to create thrust opposite to the direction of the wind, which helps to reduce the bending moment on the supporting forked mast. #OffshoreWind #OnshoreWind #EnergyTransition #EnergySecurity #EnergyIndependence #EnergyPolicy #GreenEnergy #RenewableEnergy #WindEnergy #ClimateSolution #windturbine #offshore #asktheinventor #reswindpower #windenergy #resblade

#towhomitmayconcern : https://lnkd.in/ezsfjiiX https://lnkd.in/ea2iajMR Patent granted for a rotor blade that can swap suction sides. When supported by a giant spoked wheel, a mutational leap in the conversion power of a wind turbine is possible with #resblade. Wind turbines with a capacity of 30 to 40 MW are possible with this new technology. When for example the intake side of every third rotor blade will be oriented in the wind direction, the lift force will act against the wind, resulting in two effects: First, the circumferential speed is reduced and second, the overturning moment of the bifurcated mast is reduced. #reswindpower #resonshore #resblade #asktheinventor #windenergy #windturbine #youcangetitifyoureallywant www.res-institute.com

#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 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

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

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.

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 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.
