Abstract

A turbine (2) for operation in a body of moving water has a hub (4) mounted for rotation about a vertical axis and one or more arms (8) extending outwardly from the hub. A ballasted turbine-blade assembly (16) is connected to each arm at a position spaced from the hub, such as at the end of the arm. In operation the blade assembly is movable relative to the hub in a direction substantially parallel to the axis of rotation of the hub, and the blade assembly is ballasted so that its buoyancy in the water is sufficient to support at least a portion of the arm and/or of the blade assembly above a surface of the water. The turbine is advantageously of large size, and the hub and arm are positioned above the surface of the water, with only a foil portion (20) of the blade assembly beneath the surface of the water.
