Not buying. A 400 foot antenna is hard enough to build much less a windmill.

GE offers a "standard" size of wind turbine with a rotor 341 feet in diameter. Total height of 400 feet doesn't sound like much of a stretch to me. They have been in operation at Arklow Bank Wind Park in Ireland for a couple years.

That was what I was looking for. My understanding is that the size of the wind turbine is limited more by whether or not the blades can be delivered to the site.
