Archimedean modular / multi-axis rotor (AMR)
View Patent ↗An Archimedean Modular/Multi-Axis Rotor (AMR) is a wind/fluid driven electrical generating device as described which utilizes a single foil rotor and appears in an elongated Archimedean curve tapering at its ends. A plurality of AMR's can be assembled in a multiplicity of tetrahedral or other 3-dimensional type structures that generate electric power. These structures would be manufactured to facilitate easy shipping, handling, assembly, erection and maintenance. The AMR is quiet (no prop buffeting), bird friendly, can accommodate any varying orientations to the wind/fluid direction and continues to operate even when in the direct shadow of adjacent AMR rotors.
1. An apparatus to provide a means of generating electrical energy in an environmentally clean and efficient manner comprising:
a plurality of prefabricated Archimedean Modular/Multi-Axial Rotors (AMR's) responsive to a fluid, each AMR comprising:
a) a plurality of continuously attached foils helically extending along an axis of rotation and tapered at each end, each foil further comprising:
i) a lightweight material suitable for low frictional resistance, surface wear durability and/or UV radiation resistance, such as fiberglass, nylon, carbon fiber or rigid polymer, and
ii) a cross section with a surface that is flat, concave and/or convex along its perimeter;
b) a plurality of structural tubes comprising a lightweight material such as fiberglass, carbon fiber, rigid polymer, or metal and/or alloys; and wherein each foil is sintered/bonded and/or affixed to a respective structural tube, and each structural tube is sintered/bonded and/or affixed to a structural connection device that allows clockwise and counterclockwise rotation; and
wherein each structural tube drives at least one electrical generator;
wherein the plurality of AMR's are arranged to form a tetrahedral or other 3-dimensional configuration.
