ABSTRACT:
Instead of the usual heavy structural elements or large collection of guy wires, a lightweight, portable frame for a wind turbine includes three inverted L-shaped inner frame sections supported by generally disc-shaped, heavy feet, and connected together at their top ends by a Y-shaped coupler, and three smaller inverted L-shaped outer frame sections also supported by feet and connected at their top ends to the inner frame sections, the inner and outer frame sections defining a Y-shaped structure when viewed from above. Additional strength is achieved be extending cables between the frame sections, i.e. by running a cable around the top and bottom of the Y-shaped structure.
