Claim:
1. A water turbine comprising: a base; an axle extending upwardly relative to the base; a body having an axle receiving bore positioned along a longitudinal rotational axis, and the axle being positioned in the axle receiving bore such that the body rotates about the longitudinal rotational axis; a weight bearing roller assembly positioned directly between a lower end of the body and the base to facilitate the body rotating relative to the base, and the weight bearing roller assembly bearing the weight of the body; and vanes extending radially from the body, such that flowing water striking the vanes imparts a rotational force to the body; wherein each of the vanes has a proximate end and a distal end, the proximate end of the vanes is pivotally mounted to the body with the vanes being pivotally movable between an operative position, extending outwardly from the body, and an inoperative position, resting against the body; and a hydraulic linkage is connected between pairs of vanes on opposed sides of the body, and, upon movement of one vane, of each pair of vanes, to the operative position, another of the vanes, of each pair of vanes, is drawn to the inoperative position by a hydraulic force applied by the linkage.
