A wind power generator includes a flexible sheet or fabric supported under tension within a housing frame which guides an airflow therethrough and across the surfaces of the membrane. As the airflow passes over the surfaces, vortices are created which cause the membrane to vibrate. Energy conversion units are coupled to the membrane to tap the oscillatory motion and convert it into other useful energy forms, e.g., electrical, hydraulic or mechanical. Alternately, the membrane can be formed of a plurality of fabric strips which are connected to the energy conversion unit and are dimensioned in width equal to the pitch of the vortices. The distances between the strips preferably are also equal in dimension to the vortices\pitch.

A device for generating energy derived from a moving fluid comprising: a. housing means for guiding the moving fluid generally parallel to a predetermined direction; b. means disposed within the housing means for oscillating generally transversely to the predetermined direction in response to the movement of the fluid, said oscillating means including a generally flat flexible membrane supported within the housing means under tension, said membrane positioned so as to have at least one edge disposed so as to divide the fluid flow to pass over the surfaces of said membrane such that vortices are created which cause said membrane to oscillate; and c. means coupled to at least a portion of the surface of said membrane for converting the oscillatory motion thereof into energy which is derived from the energy of the moving fluid.
