A vertical axis wind turbine comprising: a rotatable vertical shaft; a first horizontal shaft rotatably attached to the vertical shaft, and extending on either side of the vertical shaft, the first horizontal shaft having a first side on one side of the vertical shaft, and having a second side on an opposite side of the vertical shaft; a first wind turbine blade fixedly attached to the first horizontal shaft on the first side, the first wind turbine extending in a generally perpendicular direction from the first horizontal shaft; a second wind turbine blade fixedly attached to the first horizontal shaft on the second side, the second wind turbine blade extending in a generally perpendicular direction from the first horizontal shaft, the second wind turbine blade fixed at an operational angle with respect to the first wind turbine blade; a first motion limiting means attached to the vertical shaft, and adjacent to the first side of the of the first horizontal shaft, where the first motion limiting means extends into the rotational travel of the first turbine blade; and a second motion limiting means attached to the vertical shaft, and adjacent to the second side of the first horizontal shaft, where the first motion limiting means extends into the rotational travel of the second turbine blade.
