Stan,
We have a science museum a few miles from my house. They have a "modern" ?? wind turbine on campus that has a span of about 40 or 50 feet, nowhere near as large as those near you. It's on a tower, not a mast, about 100' off the ground. It NEVER turns unless the wind is HIGH! Do those near you spin in 5 KT winds? Here's the one at Tellus. Also Tellus has a Bell 47 and a Wright 1903 replica in the transportation gallery.
John Osher, the hometown self-made BILLIONAIRE and philanthropist built this museum and the Booth Western Art Museum here, in town to "pay it forward." He personally started one of the first cable TV systems in the world in the 1960's here in Cartersville, and when he sold it in the late 90's, his company had grown 1000x, and ranged from Florida to Maine.
He is an aviation enthusiast and my instrument CFI is his personal pilot. Mr. Osher tasked him with ordering his brand new airplane from Cessna and going to pick it up when it was finished. It was was just a little "private" airplane called "Sovereign." ...Like this...
Ed took some training in the sim' and then he got the keys and took off without ever having flown a REAL one.
When it first got home to KVPC, Ed took me for a short ride in it. WOW!!!! Big Bizjet. The baggage area has its own ladder and an overhead light.
