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.

A method comprising:
- directing fluid flow across an aperture of a nozzle in operational relationship with a resonant cavity, a central axis of the nozzle and the central axis of the resonant cavity are 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;
- wherein directing the fluid flow further comprises directing the fluid flow across the aperture of the nozzle where the central axis of the nozzle and the central axis of the resonant cavity are parallel.

- wherein the central axis of the resonant cavity and the central axis of the nozzle are coaxial;
- and wherein the inside dimension of the nozzle is less than the inside dimension of the resonant cavity.
