Windmills and Blades
Sep 8, 2016 11:48:04 #
I've seen literally thousands of these things...like many of you have but.......I had no clue how enormous the blades on these windmills actually are.
Made a stop at a rest area on I80 and there were three lined up in the parking area.
I tried to give some idea of the size of these blade but....I'm not sure the pictures convey how truly impressive they are.

Those things are huge when you get up close to them. Look, just one blade from the generator is an oversized load on an 18 wheeler.

Thanks for the photos of the blades on the trucks - they really provide a sense of just how huge they are. I saw some in a field several years ago and thought they were beautiful, but had no idea of size.

What setting did you use on your camera? I'll be heading to Holland in the near future. I will be bringing my Canon SL1 camera along with the 24-135 mm lens, any suggestions? I am a novice photographer. I'l appreciate any advice. I believe the place where we'll be going to is "Kinderdijk, an area with 19 dutch windmills.

Paul, I love the first shot. The simplicity of the wind turbines and the somber tones of the shot have a lot of impact for me. i also really enjoyed your shots of the blades in transit. They are really tremendous.

I love that first shot of the turbines in the fog. Yes these things are huge. The largest in the world was just completed here in Iowa. Instead of having a metal base, it was built of concrete. It's 377 feet from ground to hub. About 100 feet taller than those with metal bases.

Didn't realize they were that big. Putting in a large farm of them next town to us. Thanks for the set. Really interesting....George

And have you noticed how slowly they seem to rotate?
John, if you do the math, calculate the circumference of the circle the tips of the blades create each rotation, and count the rotations per minute, than convert to mph, you will be seriously surprised at the speed the blade tips make!

Sorry, I was busy baby sitting my Granddaughter, math was not an immediate option. Daddy has taken Granddaughter, I can now down math.
Blade for typical wind turbine is 116 feet, diameter of circular path 232+ feet. (+ is for shaft, which we will guess at 5 feet). 237 × pi (3.14) = ~744 feet circumference. Wind turbines routinely spin from 15 to 20 RPM. To simplify the math, we will use the max of 20 RPM. 20x744=14880 feet travel per minute. 14880x60(60 minutes per hour)=892800 feet travel per hour. 892800 ÷ 5280=169 mph.
Okay, math majors, prove me wrong. If my math is correct, it is impressive that the tips of the blades are hauling a$$.

Yes.....and since they are not really "mills" in any sense......is there a more appropriate name for them?
