  • Patent number: 9157414
    Abstract: A wind energy apparatus is made up of a plurality of modular wind energy devices or units. Each unit has a housing and at least two turbines mounted on the housing. Each of the turbines has a blade set extending upward from the housing. Each blade set has a vertical axis extending upward in relation to the housing. Each of the turbines has a generator connected thereto, each generator being disposed in the housing, and having a rotor and a stator. Each turbine is rotatably mounted with respect to the housing, and mounted to the rotor so that they rotate together. Each housing has a positive connector and negative connector on each side of the respective unit. The units, when placed together, connect their respective poles, positive and negative, together completing a circuit. Therefore, one may connect multiple units together.
