A vertical axis wind turbine includes two or more cells arranged one above the other along a vertical machine axis, wherein each of the cells includes a plurality of vertical blades which are arranged within the cell distributed on a concentric circle about the machine axis and which are connected so as to be able to move together on this circle and which are rotationally fixed with a main shaft, and wherein the blades in the cell are each individually mounted so as to be able to rotate about a vertical axis of rotation which in particular runs internally through them.

A vertical axis windmill turbine comprises a support structure for supporting the vertical axis windmill turbine above ground level. At least one rotor rotates upon the support structure and has a horizontal structure having a rotational axis perpendicular to the ground level. A plurality of blades are positioned within each of the at least one rotor for causing the at least one rotor to rotate on the support structure responsive to wind force. A plurality of vanes are located on each of the plurality of blades and rotate between an open position to limit drag on the at least one rotor and a closed position that provides a rotational force to the at least one rotor. The plurality of vanes rotate between the open position and the closed position of approximately 180?. A plurality of hinges each connect a vane of the plurality of vanes to a blade of the plurality of blades. The plurality of hinges have a biasing force applied thereto to slow movement of the connected vane when approaching 0? and 180?, respectively. A plurality of vane stops associated with each of the plurality of blades prevent the vane from moving past approximately 0? and approximately 180?.

The present invention relates to a vertical axis multi-stage wind turbine generator in which multiple stages are provided in a vertical axis to construct a plurality of power generating devices in one power generation facility so that backwind power is enhanced to the maximum, and headwind power is minimized to achieve an economical and efficient power generation function.

A double turbine, includes: a rotatable deflector disc including a first base plate and a second base plate facing opposing directions along an axis of rotation; a first plural number of first vanes each pivotally mounted on the first base plate and uniformly spaced around the axis of rotation by a vane spacing angle; a second plural number of second vanes each pivotally mounted on the second base plate, and uniformly spaced around the axis of rotation by the vane spacing angle, the second plural number being equivalent to the first plural number; wherein each first vane is angularly positioned with respect to the rotation axis as between two second vanes. Multiple such double turbines can be stacked with a progressive helical twist such that each one double turbine is offset from at least one adjacent double turbine by a common twist angle with respect to the axis of rotation.

The present invention relates to a vertical rotating shaft type rotational force generator that is capable of allowing a plurality of blades rotating around blade rotation shafts and simultaneously revolving around blade revolution shafts, when receiving a pressure caused by the flow of a fluid, to provide the rotational forces generated therefrom for the blade revolution shafts. Even if no separate left and right direction control power device exists, the blade revolution shafts automatically move toward positions where rotational forces generated therein are maximized, and rotation phase angles and revolution phase angles of a plurality of blades effectively interlock with each other, so that even though the blades are located at any revolution phases, they provide the rotational forces produced to the maximum according to revolution phase always in the same rotation direction for the blade revolution shafts. Further, in the case where the flow velocity and pressure of a fluid are excessively increased due to strong winds or floods, even if no separate upward and downward direction control power device exists, the blade revolution shafts are automatically tilted in a direction where the overturning moment generated in the support and foundation of the rotational force generator and the rotating torque generated in the blade revolution shafts of blades are drastically decreased, so that the rotational force generator is prevented from turning over or collapsing due to the excessive dynamic load of the fluid, and further, the rotational force generator including each blade revolution shaft is prevented from being damaged due to excessive rotational speeds, thereby optimizing the efficiency and safety thereof.

A rotational force generator is for converting fluid flow energy (e.g., wind or water currents) into rotational force. This generator has blades that simultaneously rotate on their shafts and revolve around a central revolution shaft, ensuring continuous positive torque generation. This generator automatically aligns with the fluid flow direction without requiring external power or control mechanisms. Its novel and innovative gear-shifting mechanism optimizes rotation speeds, enhancing energy conversion efficiency. The generator's modular and scalable design enables practical deployment in urban and rural environments, such as roadsides, railways, and coastal areas. By eliminating friction losses and maximizing energy output, this invention significantly advances renewable energy generation for wind and hydro power applications.

What is disclosed is a vertical-axis wind turbine that looks somewhat similar to a vertical pole during no-wind or relatively low-wind conditions, i.e., when the turbine is waiting for relatively windy conditions, and that transitions between its waiting state and wind harnessing state automatically. Yet, to automatically transition between states, the turbine uses relatively few moving mechanical assemblies and uses no electric parts. The turbine has levers attached radially to a vertical mast and one or more wings attached to each lever. Each wing's mounting angle causes the wing to move the lever to which it is attached to deploy the wing(s) attached to that lever to rotate the mast. At an approximate rotation point of the mast, to avoid the deployed wing(s) from unduly opposing the mast's rotation, the wing's angle facilitates the retraction of the wing(s). The net drag of the wing(s) serves to rotate the mast.
