Abstract:
1. A submersible electrical power generating system including a generator means for generating electricity having a support means for positioning and maintaining said generator means in a water current, wherein the improvement comprises: a rotor blade, oriented about a horizontal axis of rotation parallel to said water current, having a base with Width W, a leading edge, a tip, and a trailing edge, where said leading edge begins at a front end of said base and continues to said tip and said trailing edge begins at said tip and continues to a back of said base, where said leading edge and said trailing edge are further defined as elliptical curves having a radius of eight times the Width W where a straight line from said front of base to said tip forms a forty five angle with respect to said base, where kinetic energy in said water current causes said rotor blade to turn converting said kinetic energy to rotational mechanical energy, where said rotor blade is functionally connected to a hub having at its center a rotor shaft forming the axis of rotation where one end of said rotor shaft functionally extends interior to said generator means for transferring said rotational mechanical energy, and said rotor shaft has at an other end a perpendicular pivotal support axial extending through a channel in said hub pivotally connecting said rotor blade such that pitch of said rotor blade can be adjusted by pivoting said rotor blade around said pivotal support axial, thereafter said rotor blade is secured to said hub with a locking pin means maintaining set pitch.
