Patent ID: 7244103

Claim:
A round honeycomb rotor for propellers comprising, curved tubular trapezoids comprising a set of pieces surrounded by tubular cylinders, at the center of said cylinders is an axle operably linked to an alternator or engine, wherein the perimeters of said pieces have round curved tubular trapezoidal shapes being peripherally enclosed by said tubular cylinders which are concentric among themselves and assembled in modules, the positions of said pieces between said concentric tubular cylinders coincide or alternate forming curved trapezoidal shaped tubes that are linked among themselves, wherein the structure of said rotor has a round honeycomb shape with the axle assembled in the middle and operably linked to an alternator or engine, and wherein each tubular cylinder comprises four or more of said pieces and the cylinders are assembled in one or more pairs, wherein said round trapezoidal pieces are curved to allow a larger wind contact surface to maximize wind performance, wherein said curved tubular trapezoids can have any known regular or irregular geometrical shape, wherein said round curved tubular trapezoids have smaller wind entry surfaces and larger wind exit surfaces, and wherein the tubular cylinder comprising the largest diameter comprises an exit funnel comprising a tubular conical shape that reduces wind exit surfaces.
