  • Patent number: 9599092
    Abstract: A system for generating wind energy or wind power through multiple wind turbines. Each wind turbine can be smaller than a single conventional wind turbine. A series of wind turbines are mechanically connected by a chain, cable, or similar mechanical linkage to each other and to a single generator, which is located elsewhere (i.e., not in the nacelle or on the turbine tower). This permits the size and weight of each turbine to be reduced, resulting in the ability to generate electricity at lower wind speeds (e.g., where the wind speed is below the cut-in wind speed of 4 m/s or 9 mph for conventional wind turbines). The reduction in size and weight also reduces the inertia of each turbine, increasing its efficiency.
