In a preferred embodiment, pairs of oscillating wind paddles are mounted in the lee of a wind turbine of the lift type. An oscillating wind paddle assembly has an upper pair of paddles moving between a first position at substantially right angles to the direction of wind and a second position substantially parallel to the direction of the wind and mounted on arms extending to either side of a shaft to which they are connected through a one-way clutch, and a lower pair of paddles moving between a position at substantially right angles to the direction of the wind and a second position substantially parallel to the direction of the wind and mounted on arms extending to either side of the same shaft to which they are connected through a one-way clutch, one of the paddles being a drive paddle and the other a recovery paddle, the two pairs of paddles being out of phase with respect to one another.
An oscillating windmill comprising a vertical shaft and paddles mounted on opposite ends of a rod connected to said vertical shaft, said paddles moving alternately between a position substantially at right angles to the direction of wind and a position parallel to the direction of said wind, the paddles at one end of said rod being 90° out of phase with the paddles at the other end of said rod, travel of said rod being limited to less than 180°, said shaft being operatively connected to a generator.
An oscillating wind paddle assembly comprising an upper pair of paddles moved between a first position at right angles to the direction of wind and a second position parallel to the direction of wind, and mounted on arms extending to either side of a shaft to which they are connected through a one-way clutch, one of said paddles being a drive paddle and the other a recovery paddle and a lower pair of paddles moved between a first position at right angles to the direction of wind and a second position parallel to the direction of wind and mounted on arms extending to either side of said shaft to which they are connected through a one-way clutch, one of said paddles being a drive paddle and the other a recovery paddle, said upper and lower paddles being about 180° out of phase, said shaft being operatively connected to a generator.
In combination with a windmill of the lift type rotating about a substantially horizontal axis and mounted on a tower, an oscillating wind paddle of the drag type mounted for rotation through less than 180° on a substantially vertical shaft and rotating said shaft through said less than 180° at a pass, said shaft being supported by said tower and positioned leeward from said windmill of the lift type, and said shaft being operatively connected to a generator.
