The Vortex Hydro Turbine takes water through two upper inlets and one lower inlet from the current in which it is submerged. The upper inlets direct the water flow into cylindrical chambers with a spiral bottom to create a vortex. The top of the chambers are specifically left open to allow the water to exit and to reintegrate into the existing native flow. This movement of the water creates a low pressure area within the center of each of the chambers which is transferred to the back side of a turbine blade system through depending tubes. Water flows thru the turbine blade via the lower inlet and out the tail pipe. The low pressure from the depending tubes, aft of the blades, increases the water velocity through the blades for increased power output. The system can be scaled as a standalone unit or as an array.
