Abstract:
1. A wind power generating system, comprising a plurality of vertically stacked wind acceleration modules shaped to accelerate wind passing through the modules, wherein a first one of the plurality of modules comprises: a rotor assembly; a continuously variable transmission (CVT) mechanically coupled to the rotor assembly; an electrical generator mechanically coupled to the CVT; a sensor mechanically coupled to one of the rotor assembly and the electrical generator; and a controller electrically coupled to the sensor and to the CVT, wherein the electrical generator is configured to convert mechanical energy transferred by the CVT from the rotor assembly into electrical energy, and wherein the controller is configured to determine a range of rotational velocities and is configured to control the CVT such that the electrical generator operates within the range of rotational velocities, the range of rational velocities being based upon a signal received from the sensor.
