2. Brake Failure Resulting in Blade and Structure Destruction

3. Brake Failure Resulting in an Explosion Structure Failure Resulting in Collapse

5. Horizontal-Axis Turbine Foundation with Counterweight Wind Turbine Systems Control System Braking System

6. Close up View of Hinge Structure Close up Structural Design Column is not a standard dimension found in AISC Steel Manual Hinge Calculations

7. Wind Turbine in Lowered Position Lowering Counter Balance Tension Wires Hydraulic Cylinder Tension Wires and Hydraulic Cylinder used to balance compressive and tension forces

8.  Turbine blades not active during high wind conditions.  Turbine blades not exposed to high wind intensity in lowered position.  Structure built to withstand high wind conditions.  The structural members are easy to fabricate and are readily accessible  Ease of Constrution  Maintenance and repairs easier in the lowered position

9.  Turbine and blades exposed to debris at lowered height  Transportation will take longer due to heavy components  The pivot point can be weakened over time due to fatigue  Dilemma  low energy generation due to restriction of height

12.  At night Turbines display flashing red lights Wildlife  Birds  Scientists found that birds simply fly around the farm, or between the turbines; less than 1% are in danger of colliding with the giant structures.  Bats  Attracted to Turbines  Research on an Ultrasonic Deterrent underway

13. Located in Thomasville, GA. Southern Division focuses primarily on the Southeast Greg Orff – General Manager

14.  In Depth Cost Analysis  Determine Payback Period  Construct Prototype  Design/Fabricate Larger Blades for Turbine  Prototype Testing

15.  Designed a turbine that can survive reoccurring hurricane conditions  Designing for economic feasibility  Risk of Failure reduced with new design  Full scale design flaws can be assessed with the prototype.
