Patent ID: 10876515

Abstract:
An accelerator and water turbine assembly is provided for mounting in a tidal stream having a water turbine (12) and a water flow accelerator for providing a turbine driver current having a speed greater than that of the uninterrupted ambient tidal stream in which the accelerator has an accelerator body member (11) having a water flow facing front face (13) and side faces (14) depending therefrom around which the water flows adjacent each of the side faces as a turbine driver current and in which the water turbine (12) is mounted to be at least partially shrouded by the accelerator body member from the accelerated turbine driver current flowing adjacent and relatively close to a side face of the accelerator where the water flow achieves substantially maximum velocity and in which the accelerator is laterally spaced apart from the turbine driver current modifying effect of any other flow obstruction.
