Abstract

Multiple pivots are mounted vertically or horizontally within a rotary or stationary support structure or platform. The pivots are interconnected via members, and between these pivots, a flexible sheet of material is suspended. The mechanism operates via oscillation of a flexible sheet that captures the energy in a fluid flow, and converts it into mechanical motion. The interconnected pivots act in synchronization to vary the angle of attack of the flexible sheet, creating low pressure (lift) areas that impart force into the pivots which then move in an oscillating manner, outputting the energy captured to an energy conversion device. An alternate embodiment makes use of anchors and suspension structures that suspend the entire embodiment in the middle of a fluid flow, and enable remote connection to surfaces not immediately near the location of the device.
