Patent number: 10669985Abstract: 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.Type: GrantFiled: August 23, 2017Date of Patent: June 2, 2020Assignee: CALIFORNIA ENERGY & POWERInventors: William DeRuyter, Michael Allawos, Peter L.

Patent number: 7287954Abstract: A wind turbine apparatus, comprising an upright shaft defining an upright axis, at least two blades operatively connected to the shaft to rotate about the shaft axis as the blades are wind driven about the axis, the lowermost portion of each blade being offset, azimuthally, relative to the uppermost portion of each blade, baffles carried by the blades to project directionally to receive impingement of wind for creating torque transmitted to the blade to effect blade rotation about the axis.Type: GrantFiled: September 30, 2005Date of Patent: October 30, 2007Assignee: California Energy & PowerInventors: Christopher Piper Toby Kinkaid, Peter L.
