Patent ID: 8100648

Claim:
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, comprising: a rotor blade, oriented about a horizontal axis of rotation parallel to said water current, having a rotor base with Width BW, 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 said Width BW where the 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 first end of a rotor shaft forming at its center said axis of rotation where a second end of said rotor shaft functionally extends interior to said generator means for transferring said rotational mechanical energy, where the surface area of said rotor blade is defined by a profile substantially in accordance with Cartesian coordinates values of X and Y set forth in Table I wherein the point of origin is said rotor base which is constantly set on the X axis and the X and Y values of said tip are variably set forth in said Table I defining the profile at each X and Y value which when connected to said rotor base by said elliptical curves define the profile of said rotor blade at each X and Y value.
