Abstract:
1. A reaction turbine system for harnessing energy from liquid flow comprising a shaft; a shaft support which elevates the shaft, permits rotation of the shaft and orients the longitudinal axis of the shaft horizontally and perpendicular to the direction of liquid flow; at least one blade support member fixedly mounted to the shaft for rotation in a plane perpendicular to the longitudinal axis of the shaft; a plurality of turbine blades mounted to the at least one blade support member, each turbine blade being straight or helical, maintaining for the full length of the turbine blade a constant radial distance from the shaft as the other turbine blades, and having a tear-dropped airfoil cross-section oriented in the same direction around the circle of rotation as the other turbine blades; with the reaction turbine system arranged such that the section of the reaction turbine system where the turbine blades rotate directly against the direction of liquid flow is outside the liquid flow, wherein the liquid flow is in the form of a jet of liquid directed at the reaction turbine system.
