Abstract: The invention provides a vertical axis wind turbine to produce power relative to wind speed resulting in high torque output. During operation, all the blades of the turbine are in a continuous movement of changing their angles from fully open to fully overlap position during each rotation. At the heart of this concept is a frame circumventing the rotor, formed of a pair of top coaxial rings superimposed over bottom coaxial rings defining a central vertical axis distant from the shaft axis, each pair of top and bottom rings are freely movable by being mounted on bushings to the shaft by radially disposed beams and vertically disposed mounting members fixedly connecting the top and bottom rings. The Blade angle relative to incoming wind is controlled by these pair of rings which are controlled by the pair of weathervanes rotating on the central turbine shaft axis.

Abstract: The invention provides a single improved snow shovel and pusher combination with eight adjustable settings that is capable of providing the user an opportunity to adjust it according to their need during the process of snow removal from ground or the surface to be cleaned that could be but not limited to driveways, walkways, passages, stairs, docks and decks. To select any one of the 8 settings or adjustments of this invention, the D shaped hand grip needs to be rotated 45 degrees in clock wise direction which will change its setting or locking position. These multiple settings are useful in situations when the snow is also required to be pushed simultaneously towards right or left hand side while pushing forward before lifted and thrown away by using the snow shovel mode/setting.

Abstract: The invention provides a self directed vertical axis wind turbine which produces optimum power relative to wind speed, resulting in high torque output. During operation, all the blades of the turbine are in a continuous movement of changing their angles from fully open to fully overlap. At the heart of this concept is a frame circumventing the rotor, formed of a pair of top coaxial rings superimposed over bottom coaxial rings defining a central vertical axis distant from the shaft axis, each pair of top and bottom rings are freely movable by being mounted on bushings to the central shaft by radially disposed beams and vertically disposed mounting members fixedly connecting the top and bottom rings. Each Blade's angle relative to incoming wind is controlled by these pair of rings which are controlled by the pair of weathervanes rotating on the central turbine shaft axis.
