1. A fluid flow generator comprising:

  • a frame comprising a cavity and an opening in a surface of said frame connecting to said cavity;

    a contacting surface for contacting a fluid flow over said surface of said frame and positioned relative to said opening in said surface to at least partially enclose said cavity, wherein said fluid flow results from movement of said frame through a medium comprising a gas;

    a spring positioned to contact both said frame and said contacting surface; and

    an energy converting portion interposed between said frame and said contacting surface for converting energy from movement of said contacting surface relative to said frame due to said fluid flow.
