Abstract:
A rotational power transfer device comprising:a rotatable shaft having a first end and a second end; a housing having a first open end and a second open end, wherein said open ends are configured to form a path to receive fluid flow through said housing, said shaft operably disposed in a position transverse to said path having said first end rotatably connected to said housing and a second end rotatably connected to said housing and a remainder of said housing substantially containing said fluid path about said shaft; a plurality of arm structures attached to and positioned equally around said rotatable shaft, said plurality of arm structures extending radially outward from an upper portion of said rotatable shaft; a plurality of pin structures attached to and positioned equally around said shaft, said plurality of pin structures extending radially outward from a lower portion of said shaft; a plurality of panel members, wherein each panel member of said plurality of panel members is attached to a corresponding arm structure such that said panel member hangs downwardly from said corresponding arm structure, and wherein said panel members extend below said pin structures such that each pin structure of said plurality of pin structures is oriented in such a manner that one of said panel members is prevented from swinging in the direction of a pressure flow applied thereto from said fluid flow and an opposing panel member is not prevented from swinging in the direction of said motion force applied thereto, the force applying a rotating force on said device; a screen connected adjacent said first end an configured to prevent debris from entering without substantially affecting fluid flow thereby; and energy converting means attached to said shaft of said device for converting energy provided thereby to electricity.
