EcoAuger
A tapered, double helical, flanged auger, coupled with hydraulic circuits used to capture energy from river currents, tidal flows, and outflows from existing dams. The ECO-Auger is driven by moving water, which forces the device to rotate. This rotation is directly coupled to a high-pressure hydraulic pump located in the device’s nose cone (See below). The nose cone, which is tethered to bridges or anchored in moving water, stabilizes the torque generated from the rotation and transfers it to the hydraulic pump. The pump supplies variable volumes of environmentally-safe fluid, at set controlled high pressure, regardless of the direction or speed of rotations. This pressure feeds an oil-driven electric generator that delivers constant electrical current through a VRS (Voltage Regulation System). As the ECO-Auger rotates, the high-pressure oil flows through check valves that are connected directly in line to the oil motor driving the electric generator.
