A self-directing vertical axis turbine includes a base, a primary hub rotatably coupled to the base for rotation about a first axis, primary support arms extending from the primary hub, a positioning arm rotatably coupled to the base for free rotation about the first axis, a secondary hub rotatably coupled to the positioning arm for rotation about a second axis that is spaced apart from and generally parallel to the first axis, secondary arms extending outwardly from the second hub, and capturing elements. Each capturing element is rotatably coupled to respective primary and secondary arms. The positioning arm and the primary hub are independently attached to the base to allow rotation about the base at different times and speeds. The positioning arm rotates based upon forces imparted by a fluid upon the capturing elements and transferred to the positioning arm by the secondary arms and the secondary hub. |
