The novel floating gyro turbine uses the inertial mass generated by gyroscopic forces to stabilise the turbine around its vertical axis of rotation. The hub of a horizontal spoked wheel is connected to a rod-shaped buoy situated seventy metres above sea level. The wheel is coaxial and concentric with respect to the axis of rotation. The lower end of the rod forms a ballast body. The upper rotor, which rotates clockwise, has a diameter of 300 metres and is designed as a spoked wheel with an outer rim. Ten rotor blades, arranged parallel to the axis of rotation, cantilever from the rim on both sides by fifty metres in both upward and downward directions. The rotor is supported and tensioned by cables which stabilise it like radial spokes. Collectively, these cables, the hub and the rim form a lightweight structure that meets the criteria for a Buckminster Fuller tensegrity structure. The lower rotor, which rotates anticlockwise, is designed to function as a water turbine with a smaller diameter, thereby compensating for the precession of the upper gyro. The water turbine is driven by tidal currents or flowing water. The combined peak power output of the two turbines exceeds 50 MW, meaning that one buoy can replace seven of today's most powerful floating offshore wind turbines. Furthermore, using this structure requires significantly less material, which could lead to a substantial reduction in electricity production costs.

The RES-Gyro Turbine saves resources by lightweight construction

The load-bearing components of a conventional wind turbine with a horizontal axis of rotation are subjected to continuous bending loads. In contrast, the gyro turbine with a vertical axis of rotation presented here has components that are predominantly subjected to tensile and compressive forces. The centre wing segment of the three-part rotor blade simultaneously forms part of the load-bearing structure, enabling the construction of a lightweight rotor basket comprising compression and tension members held in place by circumferentially underspan ring beams. The motor-generator is integrated into a buoy with a counterweight at its lower end. In underwater conditions, a counter-rotating water turbine delivers additional energy and enhances the hydrodynamic stability of this dual-purpose offshore installation.

Tensegrety Structure For A Wind Turbine: https://lnkd.in/eNYWFN2R

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.
