Filed:

Apr 9, 2010

Appl. No.:

12/798717

Inventors:

William DeRuyter - Norco CA, US
Michael Allawos - Glendora CA, US
Peter L. Coye - Claremont CA, US

Assignee:

California Energy & Power - Glendora CA

International Classification:

F03D 7/06

US Classification:

415 21

Abstract:

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