ABSTRACT:
An apparatus is provided for generating electricity in response to a fluid flow. The apparatus includes a top rotor element coupled to a center axis with an arm extending substantially perpendicular to a center axis. The arm moves in response to the fluid flow to rotate the center axis. The apparatus also includes a bottom rotor element coupled to the center axis also having an arm extending substantially perpendicular to the center axis. The arm of the bottom rotor element is substantially fixed in a position relative to the arm of the top rotor element, wherein the position is offset about the center axis by about 90° from the top rotor element. The apparatus further includes intermediate rotor elements stacked between the top rotor element and the bottom rotor elements, wherein the intermediate rotor elements are in positions successively offset about the center axis in degrees to produce the 90° offset of the bottom rotor element relative to the top rotor element, and each intermediate rotor element includes a tongue and a groove for coupling to the adjacent rotor element. The tongue and groove of each intermediate rotor element are offset from one another to produce the successive offset of the rotor elements.
