Abstract: An apparatus for producing high output and low cost/time, sustainable energy from a fluid flow, such as wind or water natural currents. 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.

Abstract: An apparatus and method for producing high output and low cost/time, sustainable energy (e.g., wind or water) via natural currents that is environmentally friendly and includes a gravity-assisted equalizing control system is provided. Wings with a large surface area can be included in the design, as well as an optional 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 wings of the device, the fluid flow induces motion in the wings, which causes a shaft to move, creating torque at the generator. The outcome is a coordination of harmonizing the wings pitch angle to the natural frequency of a fluids specific velocity. The device can adapt itself to the velocity of the surrounding fluid through a rotational sweeping control system that produces a more streamlined profile to maximize reliability.
