Page "Mars Hill, Maine" Paragraph 15

Mars Hill Mountain underwent a wind power project in the fall of 2006.

Developers installed 28 GE 1. 5 MW Wind Turbines along the top and northern section of the mountain, which overlooks Canada.

The windmills are assembled in multiple parts.

The towers, which are composed of three support sections stacked one on top of another with a combined weight of 20, 000 pounds, are 80 meters ( 262 feet ) tall.

Each of the turbine's three blades ( together, a rotor ) are approximately 37. 5 meters ( 123 feet ), for a total rotor diameter of approximately 75 meters ( 246 feet ).

Rotor diameters are comparable to the wingspan of a Boeing 747 jet-liner.
