  • Patent number: 8734109
    Abstract: A foldable electric fan, comprising: a fan head, a support tube and a base, a turnover mechanism for turning the fan head up or down is provided between the top of the support tube and the fan head, is disclosed. Further, the base is foldable, and the electric fan can be arranged into a desk fan or a floor fan by turning the fan head up or down, and can be used for several different purposes in more broad fields. The fan head and the base of the electric fan can be folded-up, which reduces the space it occupies and cuts down the cost of package and transportation. Moreover, the foldable electric fan effectively reduces the inconvenience of traditional electric fans which need to be detached into several parts during package and transportation, and then assembled together for use.

  • Patent number: 8678767
    Abstract: A wind turbine includes two sets of blades. A first set of blades is placed at a front location of the wind turbine. A second set of blades is placed behind the first set of blades. The first set of blades turns in an area within a first circumference. The second set of blades are mounted at a location sufficiently away from an axis of rotation of the wind turbine so that the second set of blades turns within an area that is within a second circumference and that is substantially outside the first circumference.

  • Patent number: 8591169
    Abstract: A power generation system that generates power in low flow situations is disclosed. The system includes a set of vanes, wherein each vane is mounted on a corresponding mast, so as to selectively transmit energy from the flow medium to a rotor shaft or to freely deflect in the direction of flow, depending on whether the flow impinges on the vanes in an energy-producing or a non-energy-producing direction. This is achieved by mounting each vane on its mast, so that it deflects in the flow direction when the vane is subjected to non-energy-producing flow energy, and also coupling each vane to the mast of an adjacent vane, so that the vane exerts a pull force on the mast of the adjacent vane, when the vane is capturing energy-producing flow energy.
