Abstract: Methods, systems, and devices for dynamic wind turbine rotational speed control are described. The method may include attaching a vane shaft to a support arm of the wind turbine, the vane shaft partially inserted into a cylindrical aperture of an airfoil of the wind turbine, rotating an airfoil around a vertical axis of the wind turbine, and controlling, via a torsion spring of the wind turbine, when a rear stop of the speed control assembly exerts a force on the airfoil to reduce the rotational speed of the wind turbine, where the torsion spring is configured to facilitate the rear stop to exert the force on the airfoil when a rotational speed of the wind turbine around the vertical axis exceeds a set rotational speed, where a portion of the vane shaft is inserted into a helical portion of the torsion spring.

Abstract: A method for balancing a wind turbine having a vertical axis. The method includes transmitting, via a turbine shaft, mechanical power to an alternator or generator; supporting, via a support structure, a vane shaft and the turbine shaft; and balancing the wind turbine based at least in part on freely moving objects within a hollow chamber of a balancing channel. In some cases, the support structure couples the vane shaft to the turbine shaft. In some cases, the balancing channel is coupled to the vane shaft.

Abstract: An embodiment of a vertical axis wind turbine (VAWT) with a turbine shaft for transmitting mechanical power. Coupled to the turbine shaft is a support structure with a vane rotatably coupled to the support structure at a vane shaft. The vane rotates the vane shaft, support structure and the turbine shaft around the center of the turbine shaft when the vane is acted upon by the wind. A centrifugal compensation rod is connected to the vane. The centrifugal compensation rod counteracts the centrifugal forces acting upon the vane as the vane rotates about the center of the turbine shaft. Embodiments of the vertical axis wind turbine increase the efficiency of the wind turbine by reducing wind resistance. Some embodiments develop power when the vanes move into the wind instead of simply reducing drag on the side of the turbine that moves into the wind.
