Patent ID: 7633175

Claim:
A process for producing electric power from a fluid flow comprising the steps of: designing a blade with a certain natural frequency such that the blade will resonate at a specific fluid flow across the blade, the blade having an airfoil cross sectional shape with a leading edge and a trailing edge, the blade having a pressure side wall and a suction side wall extending between the leading edge and the trailing edge; securing one of a magnet or a coil to the blade; securing the blade to a support such that the blade can vibrate as the fluid flows across the blade; positioning the blade with the leading edge being an upstream end in the fluid flow; securing the other of the magnet or the coil to a support near where the one of the magnet or the coil such that an electric current is produced in the coil as the magnet moves near the coil; and, passing the fluid across the blade at a speed such that the blade vibrates at a natural frequency to produce electric current in the coil.
