Title:

FLUID TURBINE SYSTEMS

Document Type and Number:

WIPO Patent Application WO/2010/027635

Kind Code:

A3

Abstract:

Various fluid turbine systems (100) and methods are described. The turbine (100) can be a vertical axis wind turbine configured to generate power from wind energy. The turbine system (100) can have a blade assembly (140). The blade assembly (140) can have a plurality of blades (142, 144, 146, 148) rotatable about an axis (Y). The turbine system (100) can have a concentrator (120) positionable upwind and in front of a return side of the blade assembly (140). The concentrator (120) can define a convex surface facing the wind. The turbine system (100) can also have a variable concentrator (110) positionable upwind of a push side of the blade assembly (140). The variable concentrator (110) can be adjustable between a first position and a second position, the variable concentrator (110) being capable of deflecting more wind toward the turbine (100) in the first position than in the second position.
