Abstract
An improved rotor blade used in combination with a submersible electrical generator comprises a rotor base with width W, a leading edge, a tip, and a trailing edge. The leading edge and the trailing edge are defined as elliptical curves having a radius of 8.0(W). A straight line drawn from the front of the base to the lip forms a forty five degree angle with respect to the rotor base. The rotor blade is functionally connected to a rotor shaft through a pivotal support axial which allows the pitch of the blade to be set and maintained. The pitch is set to harness the kinetic energy of flowing water thereby generating electricity.
