Crookwell wind turbine facts.

Each turbine is 450 feet agl. Dia of the blades is 100 meters.

100 meters is a foot ball field.

Now work out at a 12 knot wind speed tip speed.

Look at take off speed of say a 747. Wing length.
Tip vortices

8 deaths in the USA from a direct hit from a blade/ tower
18 accidents from guild wire hits.

Now these don't produce power more than 30% of the time.




These turbines are constant vortices.
