A high efficiency induced-flow wind power system engages and converts both potential (to-pull) and kinetic (to-push) wind energies to effective airflow power, delivering induced (accelerated) airflow power in a controlled flow field to a turbine/rotor, impelling a 360-degree torque on the turbine/rotor and, as a result, extracting (converting) more than 80% of the combined effective wind power to mechanical power. The induced push-pull effect results in higher efficiency wind-to-mechanical power extraction (conversion). The induced-flow wind power system can be coupled with (i) an electrical generator, inverter/converter for generating AC and DC power, (ii) pressurized vessel for effective energy storage (iii) a pressurized structure, such as an air supported structure, to ensure its structural integrity. The Induced-Flow Wind System embodiment comprises: a passive-flow nozzle, an active-flow nozzles and a turbine encased in housing interposed within the flow field of the active-flow nozzle and coupled with an electrical generator or a compressor.

The high performance hybrid turbine, if used as a wind turbine, can operate at much higher wind speeds than conventional wind turbines.
