You are absolutely wrong about the noise. I stood near the base of one of the largest wind turbines made when in full operation. No sound from the generator equipment and only a faint whish as each blade passed by. I had to listen carefully to hear it.

Turbine means only a rotor or vanes driven by movement of a fluid or air. The comparison to a jet engine noise is as far off base as anyone could ever get.

Paradoxically, small turbine wind generators are significantly noisier than the large ones. You would NOT want to have a small turbine (propeller) one attached to your house, and nearby neighbors might not like it either, depending on how nearby they are. Residential propeller generators are best when they can be 50-100 feet away from the structure they are supplying power to.

This is not a problem with the rotating (spinning) ones pictured in Reply #9

I have to respectfully disagree with you.

The noise is not necessarily generated near the rotors or tower. It is the turbine that is loud and they can be located several hundred meters away from the tower. A turbine is necessary to generate electricity.

While the health risks are debatable…physics are not.

Kracken...

I dont know how familiar you are with the principles of generating electricity, but it basically requires magnets (attached to an axle) spinning inside a coil of wire... (the principle of induction) The bigger the magnets & coil winding the more electricity you can generate... but like any mechanical device, the more mechanical energy (electricity) you want to produce the more kinetic energy (wind, steam, water) you need to convert to mechanical energy to spin the magnets. Anyway.. I digress.

A wind tubine (windmill) is no different from any other turbine.. (water, steam etc.) The axle shaft is always directly attached to the spinning blades converting the kinetic energy to mechanical energy. In the case of a wind turbine the spinning axle is directly connected to the blades. This puts the turbine on top of the support post directly behind the blades... not anywhere on the ground.
