14  During high winds, turbine not  active  exposed  Structure durable in high winds  Ease of Fabrication and Construction  Ease of Access for Maintenance and Repairs 14

15  Debris present at lowered position  Transportation will take longer due to heavier components  Hinge fatigue  Dilemma  Height Restriction 15

32  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 32

33  Delays in component procurement  Minor design adjustments for machine shop production  Assistance needed in implementing electrical components  Output of anemometer difficult to work with  Discovery of permanent placement for prototype 33

34  Successful design of turbine system for hurricane-prone regions  Fabrication of a prototype  Structurally sound with little to no stresses that may cause failure or fatigue  Fail-safes implemented to account for any malfunctions 34
