The innovative structural design makes it possible to build a large wind turbine with a vertical axis of rotation. Compared to a conventional three-blade turbine, a single wind column of this type replaces ten to twenty conventional turbines. The cost of electricity is halved. The turbine operates at maximum efficiency at wind speeds three to four times higher than average and therefore has no negative impact on flora and fauna. Due to its filigree design, it is hardly noticeable in the landscape, at least from a distance. I am willing to license this invention to others on the basis of a fair agreement.

RES-GigaTube: Patent granted! https://lnkd.in/eVcSpURp https://lnkd.in/dzukUu5
Build one wind turbine instead of ten to solve the energy shortage! One GigaTube produces more electricity than ten of the most advanced 7 MW horizontal-axis wind turbines. The rotor blades form an integral part of the supporting structure and can be adjusted to ensure that, regardless of the wind direction, the suction side of the blades is always facing into the wind. Additionally, the GigaTube has a new generator which uses electromagnetic force to generate electricity and compensate for the tilting moment of the rotor. As the support structure is primarily designed to withstand axial forces, much less structural mass is required than in conventional wind turbine construction, where the support structure must withstand pressure and bending tension forces, necessitating expensive reinforcements. Thanks to economies of scale, electricity production costs can be reduced by about half. If Tesla can build a Giga Factory in two years, why can't we build this concept in one? In total, only two thousand of these GigaTubes would be needed to meet the impending climate goals by 2035.

#resvawtcolumn4 Introducing the Queen of the Baltic: https://lnkd.in/daF7kDaS
In terms of converting wind energy, sailing is a more effective method than the conventional approach. Consider a wind turbine with an inflow area of around 151,000 square metres. When operating at wind speeds of 15 metres per second, it can deliver up to 155 MW. Furthermore, it continues to generate additional energy at wind speeds exceeding 15 metres per second, even after the conventional technique has reached its maximum capacity. This innovative wind turbine design is a tangible reality. Reducing the weight would also significantly decrease the cost of electricity generation. The turbine is made from lightweight steel that can be quickly assembled, taken apart and recycled. The following section will present a number of the advantages of this design. Instead of a mast, a highly rigid, substantial cylinder constructed as an airy lattice shell structure is used to accommodate the entire bending moment. The cylinder incorporates circumferential sub-spanned compression rings in its transverse stiffeners, enabling it to act as a giant bamboo tube structure with high stiffness in bending, shear and torsion. The central segment of the three-part rotor blade comprises a vertical tower that houses an elevator shaft and a staircase. This provides access to the electrical actuators of the swivable, non-load-bearing leading and trailing edge segments of the rotor blade throughout the entire length of each of the five towers. The five towers are connected by eight circular ring beams in a regular pattern of spacing. These beams, in conjunction with vertical cross bracing, constitute the open grid shell structure of the giant rotor. The suction side of the rotor blade is always perpendicular to the wind direction, with the suction side of the asymmetric wing profile oriented leeward. This is achieved using vertically spaced actuators that align with turning points perpendicular to the wind direction. Altering the suction side of the rotor blades is time-consuming, but highly beneficial in reducing stress peaks caused by sudden changes in load. These peaks represent a significant drawback of a conventional Darrieus rotor, resulting in poor performance. The abundance of kinetic energy in our gaseous atmosphere provides a rich source of potential for growth through the utilisation of regenerative energy. The entire wind energy industry is poised for a transformative leap forward.

#resvawtcolumn5 Giant Turbines need Giant Blades: https://lnkd.in/dQZA_Ush
When it comes to converting wind energy, sailing is much more efficient than riding a merry-go-round! The video shows the red, load-bearing central segment of one of the five three-part rotor blades. Similar to a sailing yacht, the blade rotates around the rotor's axis and completes a turn of its suction side, adjusting the diameter perpendicular to the wind direction. The 18 m long, 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 with a step-lock gearbox that shifts the suction side of the rotor blade. The VAWT's rotor has a diameter of 240 metres, is 630 metres high, and has an intake area of around 151,000 square metres. A single GigaTube will deliver 80 MW at wind speeds of 12 m/s and up to 155 MW at 15 m/s, whereas conventional technology requires pitch control at this speed. 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 lower than the power-to-weight ratio of a conventional 7 MW wind turbine. Not only does lightweight steel construction reduce construction costs through a modular building system that can be easily assembled, disassembled and fully recycled, it also leads to a dramatic reduction in electricity generation costs. This is critical to the success of the transition from fossil to green energy generation.

Patent granted in Germany: https://lnkd.in/eVcSpURp
Listen, mariners! When it comes to converting wind energy, sailing is much more effective than riding a merry-go-round! Three of these giants are revolving in Osaka Bay, right in front of the Akashi Peninsula. In the background, you can see the Akashi Kaikyo suspension bridge. Each VAWT's rotor has a diameter of 240 metres and stands 630 metres tall, covering an inflow area of around 151,000 square metres. At wind speeds of 12 m/s, just one GigaTube will deliver 80 MW; even at wind speeds of 15 m/s — when conventional techniques require stall regulation — it continues to convert energy up to 155 MW and beyond. The total weight of the steel construction is about 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 cuts construction costs effectively due to a modular building system that can easily be assembled, disassembled and completely recycled, but also leads to a drastic reduction in electricity production costs, which is crucial for the successful transformation from fossil-based to green energy production.

#resvawtcolumn7 Doubled efficiency at half the weight: https://lnkd.in/e5Bu4Dvv
PCT application published with research report! https://lnkd.in/et9qwc6S https://lnkd.in/eVcSpURp
Despite its all-steel construction, the wind column weighs less than half as much as a conventional 7 MW horizontal wind turbine. While a HAWT has to be down-regulated at wind speeds of over 12 m/s, the wind column can operate without regulation at speeds of up to 15 m/s. For offshore turbines, which are often exposed to strong winds, the electrical yield in this range can be doubled or even tripled compared to a conventional HAWT. This is possible because the VAWT's optimum performance is achieved at an inflow that is 'only' three times the wind speed. The centre segment of the three-part rotor blade is designed as a rod-shaped support element of the cylindrical lattice shell structure. Meanwhile, the nose and trailing edge segments of the rotor blade can be adjusted by up to 9° relative to the centre segment. This periodically changes the suction side of the rotor blade from the inner to the outer side of the orbit and vice versa. The diameter is aligned perpendicular to the respective wind direction, with two turning points that align the asymmetrically profiled rotor blades in both halves of the orbit to the leeward side. The rotor blade is divided into longitudinal sections, each with integrated actuators that perform a setting and holding function. The cable-stayed lattice shell design is scalable and can be made smaller or larger than the 200 m tower shown here. Technical specifications:

Can you believe that the wind column on the left requires half the weight of the conventional wind wheel on the right to achieve the same power at wind speeds up to 12 m/s, and can produce twice or even three times the power at speeds greater than 12 m/s?

Taking a closer look at the advantages should convince you of the concept's superiority. The turbine pictured here is slightly taller than the ENERCON E126, one of the most efficient and well-designed HAWTs. With a height of 235 metres and a diameter of 70 metres, the VAWT GigaTube on the left has a much better power-to-weight ratio of 360 tons/MW than the ENERCON E126 with a ratio of 933 tons/MW. The column design uses variable asymmetric profiles that provide up to 30% more lift than a Darrieus rotor with symmetric profiles. 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. Additionally, the leeward blades are connected to the windward blades. At wind speeds above 12 m/s, the centrifugal force outweighs 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.

#rescolumn15 A Different Philosophy Converting The Wind Energy: https://lnkd.in/ecxAX7X6
PCT application published with research report ! https://lnkd.in/et9qwc6S
Imagine a wind turbine with an inflow area of about 14,000 square metres that delivers the same amount of electrical energy as the best conventional 7 MW wind turbine at wind speeds up to 12 m/s, but with half the structural weight. On top of this, at wind speeds above 12 m/s, when the conventional technique already requires stall regulation, it delivers a power output that is double or triple that of the conventional turbine. Yes, this wind turbine exists as a design. #reswindcolumn. Its reduced weight 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. Some of the advantages of the design are that, 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 in the form of circumferentially sub-spanned compression rings, meaning the cylinder acts like a giant bamboo 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 integrated into the central part of the rotor blade cause the asymmetrically profiled blades to align with the leeward side of the wind direction. This allows a diameter with turning points to be aligned perpendicular to the wind direction. The suction side of the rotor blades changes gradually, which is helpful in reducing stress peaks caused by abrupt load changes on a conventional Darrieus rotor. There is so much kinetic energy in our atmosphere that it can easily be used to drive growth through regenerative energy. The entire wind energy industry is ready for a leap forward.

International pct application : Examiner's report available.
The patent examiner's report for the E-wing, the electric adjustable rotor blade, is available here at the RES Institute. Only documents classified as A could be found to be relevant to the state of the art. If you would like to learn more about this invention, please get in touch. The example shown here features a large wheel that is rotated by wind power. In 1946, R. Buckminster Fuller stated that 'winds are drafted and not blown', and he was absolutely right in his different and prospective description of the phenomenon of wind. Today, we know that wind is a complex, three-dimensional phenomenon driven by pressure differences in the atmosphere and the effects of the Earth's rotation. Therefore, the current model of cutting out a flow column from the atmosphere that aims at the rotor plane of a wind turbine, where it will be slowed down by three rotating blades capable of converting up to 49% of the wind's kinetic energy into rotation, according to Betz's law, is only one approach to converting the linear fraction of the flow into rotational energy. There are others. One outstanding advantage of vertical-axis wind turbines is that the rotor does not need to be adjusted to face perpendicular to the wind. A vertical-axis wind turbine that uses asymmetrical wing profiles for the rotor blades is more efficient than 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 the Øresund Bridge, is twice as effective as it harvests wind energy in both the windward and leeward halves of the rotor's 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 parts of the outer compression ring of a spoked wheel, which is stabilised by steel cables arranged in a radial pattern. The compression ring is also used as a walkable maintenance corridor, providing access to the rotor profiles for inspection and maintenance purposes. The middle section of each rotor blade cantilevers 50 meters up and down from the outer compression ring.
