Regarding the blades striking the tower, part of the problem is that most of the turbines currently being manufactured are upwind turbines. When the wind blows it flexes the blades toward the tower. Downwind turbines don't have that problem, but they do have what's called "tower shadow." Every time the blades pass behind the tower they enter an area where the wind is blocked by the tower. This causes a cyclic loading on the blades, which contributes to fatigue failure and an increase in noise.
Intersting. A study of the physics in making them work must have been fantastic.

I'm guessing around 100-120 feet, if ya figger that a regular trailer would be around fifty feet...

The usual size for a trailer is currently 53 feet end to end and it weighs 16,000 lbs empty.

The cost to replace a windmill is around one million per.

I see these things all the time.

Plus $3.99, shipping and handling.

I have four in three different internet shopping carts right now.

Should I get shipping insurance?

Use a Post Office's priority mail box and you don't have to weigh them.

Given the pictures in the op, this seems a little negligent.

There's something funny about that picture.

Looks like something to warn trucks of the clearance on the signs ahead.
