Abstract
A vertical axis turbine is disclosed, having a vertically oriented rotor shaft, a plurality of radially extended arms rotatably mounted on the rotor shaft, and a chassis at the distal end of each. For each chassis, an upper blade set is on an upper portion, having upper blade panels interconnected pivotally by upper guide links, and a lower blade set is on a lower portion, having lower blade panels interconnected pivotally by lower guide links. Each chassis has an upper shaft with an upper gear, coupled to the upper guide links, and a lower shaft with a lower gear coupled to the lower guide links. The upper gear and the lower gear mesh, limiting rotation of the upper shaft and lower shaft to opposite directions with similar rotational speeds.

A vertical axis turbine, comprising:
- a rotor shaft, the rotor shaft being vertically oriented;
- a plurality of radially extended arms rotatably mounted on the rotor shaft, each radially extended arm having an end distal from the rotor shaft;
- a plurality of chassis, each of the chassis being attached to the distal end of a respective one of the radially extended arms;
- mounted on an upper portion of each chassis, a corresponding upper blade set including a plurality of upper blade panels and an upper guide link pivotally coupled to the plurality of upper blade panels, each of the upper blade panels including an upper panel first edge and an opposing upper panel second edge, each of the plurality of upper blade panels being pivotally mounted on the chassis from the upper panel first edge and being rotatable between a closed position and an open position around a pivotal axis defined by the upper panel first edge, the plurality of the upper blade panels being interconnected pivotally from the upper panel second edge by the upper guide link;
- mounted on a lower portion of each chassis, a corresponding lower blade set including a plurality of lower blade panels and a lower guide link pivotally coupled to the plurality of lower blade panels, each of the lower blade panels including a lower panel first edge and an opposing lower panel second edge, each of the plurality of lower blade panels being pivotally mounted on the chassis from the lower panel first edge and being rotatable between a closed position and an open position around a pivotal axis defined by the lower panel first edge, the plurality of the lower blade panels being interconnected pivotally from the lower panel second edge by the lower guide link;
- associated with each chassis, an upper shaft coupled with the upper guide link, and an upper gear mounted on and rotatable with the upper shaft, the coupling being configured such that an upward or downward movement of the upper guide link couples to and urges a rotation of the upper shaft about the longitudinal axis of the upper shaft;
- and
- associated with each chassis, a lower shaft coupled with the lower guide link, and a lower gear mounted on and rotatable with the lower shaft, the coupling being configured such that an upward or downward movement of the lower guide link couples to and urges a rotation of the lower shaft about the longitudinal axis of the lower shaft, the lower shaft including a lower gear mounted thereon and rotatable therewith;
- wherein, the upper gear and the lower gear mesh with one another.

A wind turbine, comprising:
- a rotor shaft, the rotor shaft having an axis;
- a radially extended arm, movably supported by the rotor shaft, having an end proximal to the rotor shaft and having a distal end, the movable support being configured such that the distal end is movable about the axis;
- a chassis attached to the distal end of the radially extended arm, the chassis having an upper portion and a lower portion;
- an upper blade panel, having an upper panel first edge and an opposing upper panel second edge, the upper blade panel pivotally mounted on the upper portion of the chassis from the upper panel first edge and being rotatable between a closed position and an open position around a pivotal axis defined by the upper panel first edge;
- an upper guide link pivotally coupled to the upper panel second edge;
- a lower blade panel, having a lower panel first edge and an opposing lower panel second edge, the lower blade panel being pivotally mounted on the lower portion of the chassis from the lower panel first edge and being rotatable between a closed position and an open position around a pivotal axis defined by the lower panel first edge;
- an upper shaft coupled to the upper guide link in a configuration wherein a movement of upper guide link couples with a rotation of the upper shaft;
- a lower shaft coupled to the lower guide link, in a configuration wherein a movement of the lower guide link urges a rotation of the lower shaft;
- and
- a coupling between the upper shaft and the lower shaft, the coupling being configured to mutually couple rotation of the upper shaft and lower shaft.
