Some cool turbine blade machining pictures:
No wind.

Lafayette, Colorado. Notice the seven birds perched on the old wind turbine. Seeing them produced me realize that I’ve by no means seen this windmill spinning.
I feel this type of wind machine, iconic and symbolic of the old west, was used to pump water. I see this windmill almost each day going to perform on 95’th street, just south of Arapaho Road. It’s on Shannon’s farm, also identified as "Red Barn Farm.
These windmills often make me think of the old western motion pictures and Giant starring Rock Hudson, Elizabeth Taylor, and James Dean.
I’ve typically wondered what the science is in selecting the number, length, and shape of the blades. The new wind turbines for creating electrical power generally have only three blades but they are quite long. The 1 pictured has 18 blades. I have been told that the amount of energy that a wind turbine generates is proportional to the blade length. Accurate?
The mountains in the background are the Flatirons in Boulder.
