  • Wind energy conversion devices
    Patent number: 10253755
    Abstract: A wind turbine for harvesting energy from both horizontal and vertical wind currents having an open frame structure and a central passage through the structure with at least three wind energy harvesting generally vertically disposed and rotatably mounted blades positioned about the central passage and at least three wind energy harvesting generally horizontal blades projecting radially from the central vertical axis of the device. The open frame structure includes a unique rod and cable central structure offset from the periphery of the frame. In one embodiment, the frame structure is suspended from a rotatable hub at the top of a stationary mast.
    Type: Grant
