I understand this may not be of interest to some of you but I found it very impressive!
Recently I had the privilege of seeing a commercial wind farm in Lincoln Co. Kansas.
I had NO idea how large these machines were. I am attaching photos that may help put their mammoth size to perspective! The props were turning at about 20 RPM's. I have a small video available if anyone is interested. I'm not sure how large of file is permitted to be uploaded to my folder!
Also I am also attaching a couple informative links containing information about the pictured wind farm.

This photo is approximately 5 miles away from the nearest one pictured.
There is a 1-ton pickup at the right hand base of the Left tower.
