The apparatus has one or more wings that pivot and change their angle of attack, and oscillate with a counterbalance system that synchronizes the wings' position and speed with a mechanical leverage point on the body of the device. When a fluid flows past the wing, a pendulum causes the wing to constantly change its angle of attack such that the oscillation can harmonizing to the natural frequency of a fluid's specific velocity. The pivoting is translated into mechanical force on a shaft, which then can create torque at a generator or pump.
