Patent ID: 8587144

Claim:
A power generator assembly for using kinetic energy from a flowing fluid to generate power, the power generator assembly including: a blade assembly having a head end for facing oncoming flowing fluid, a tail end spaced from the head end for facing in the direction of flow of the fluid, and a rotational axis extending between the head end and the tail end, the blade assembly including a blade arrangement which is arranged in generally helical fashion about the rotational axis, and at least one mounting formation connected to the blade arrangement, each mounting formation being adapted to permit mounting of the blade assembly for rotation about its rotational axis, so that in use fluid flowing past the electrical power generator assembly interacts with the blade arrangement to rotate the blade assembly about its rotational axis; a stator including one or more blades of adjustable pitch; and a generator drivingly connected to the blade assembly for generating power in response to rotation of the blade assembly.
