Since wind speed increases with height, increases to the tower height can mean enormous increases in the amount of electricity generated by a wind turbine. Our's - Aluminum Body, Durable and Long Lasting - Unlike rubber, PVC Rings are much more durable will not harden and crack and cause leaks - Bearing are covered and will not rust / leak. Competitor's - Plastic Body , becomes brittle under the Sun's UV Ray - Rubber ring will harden after approximately 1 year of use and will start cracking and leaking - Bearing are exposed and will rust / leak. Adjustable blade degree with included degree adjusters (Shims) Increase/decrease blade angle by installing degree adjuster under the blades "+" on the right side = Increase angle = More Torque, Less Speed "-" on the right side = Decrease angle = Less Torque, More Speed Below are comparisons between the our blades and competitor's blades. Pros - 140mm diameter, 10% larger than competitor's - High blade capacity, allow up to 6 to be installed - Covers the entire face plate to eliminate vortex.
Cons - 125mm in diameter - Only allows 3 blades to be installed - Does not cover face plate completely. Ours - Dual Metal ball bearing to prevent vertical vibration - Yaw shaft diameter: 40mm - 3cm of stabilizing distance with 2 bearings - No vibration = Increase in efficiency - Reduction in noise output - One piece design Yaw body provides more stability. Competitor's - Single bearings will not eliminate vertical vibration - Yaw shaft diameter: 35mm - Stabilizing distance effectively shorten to 1.4cm with one bearing (53% reduction) - Vibration will cause bearing to grind on yaw shaft and create a bigger play, which in turn will cause more vibration in a never ending cycle - 2 pieces design Yaw body is less stable. With Nose Cone - Smooth Performance.Without Nose Cone - Air current spins into tiny vortexes. Rotating blades present the most serious mechanical hazard. The blades may be moving at velocities over 275 miles per hour (440 km/hr).
At this speed, the tip of a blade is nearly invisible and can cause serious injury. Under no circumstances should you install the turbine where a person could come in contact with moving rotor blades. The installer of these blades is solely responsible for the use or misuse of these blades. We assume no liability for ANY injuries caused by these products. NO OPERATING COST GENERATES ELECTRICITY FROM THE ABUNDANT RESOURCE.
