Abstract: 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.

Abstract: The Vortex Hydro Turbine takes water through an inlet from the current in which it is submerged. The water inlet reduces the cross-sectional area for the water that flows into the vortex chamber and thus increases the velocity of the water into a specially designed cylindrical chamber. The top of the chamber is specifically left open allowing the water now traveling at an increased velocity to disperse toward outlet as it rotates around the chamber, and then reintegrate into the existing environmental regime. This expansion creates a low pressure area in the center of the vortex chamber that is applied to the back side of a turbine blade system either directly or through a connecting tube depending on configuration.

Abstract: A tablet comprising a core which is at least partially coated with an outer layer obtained by electrostatic deposition of a powder and subsequent fusing of the deposited powder to form a film characterised in that a surface of the tablet coated with said outer layer is contoured to provide higher regions and lower regions, the outer layer having a different colour in said lower regions to the outer layer in said higher regions.
