ABSTRACT:
An improved turbine and generating system for generating electrical power from the energy of flowing water, such as a tide, in a water course are disclosed. The turbine features peripheral inward flow and axial outward flow. A flow divider means is provided to ensure that the outward flow is substantially uniform along the turbine shaft in both directions. The turbine wheel is made up of radially extending scoops and generally circular disks, to define chambers. Preferably the chambers are of continuously decreasing cross-sectional area, measured perpendicular to water flow therethrough. Baffles may be provided preventing water from entering certain of the chambers formed between the scoops and disks of the turbine to ensure that a net rotational impetus is given to the turbine by water flow thereagainst. The structure supporting the turbines and generators in and above the watercourse may include a causeway for vehicular traffic.
