A fluid flow-driven energy conversion system configured to oscillate in the presence of fluid flow. The system comprises an adjustable electromechanically controlled fluidfoil, a balance beam, a compensatory weight and an angle of attack positioner to adjust the angle of attack of the fluidfoil with respect to fluid flow. The fluidfoil is controlled to permit a consistently optimum angle of attack into the prevailing flow. The kinetic energy of the oscillating action is transferred to a connector for energy transfer to one of a variety of energy storage systems for converting the energy of the linear oscillating motion to other desired forms of energy.
