Abstract
Extracting energy from wind. At least some of the illustrative embodiments are methods including: directing fluid flow across an aperture of a nozzle in operational relationship with an resonant cavity, a central axis of the nozzle and the central axis of the resonant cavity nonconcentric, and the resonant cavity has a resonant frequency; creating pressure waves within the resonant cavity, the pressure waves created at least in part by vortices within the fluid flow across the aperture; and extracting energy from pressure waves within the resonant cavity.
