Has anyone here actually done any serious research on modern domestic wind

I could phone all sorts of places and get lots of quotes but wondered if the

Things don't always run smoothly.

Blades 'flew off' wind turbine

A farmer from Upper Ballinderry has told how the massive
blades of a wind turbine installed on his land came loose
and flew over his house before crashing to the ground.

Gavin Hayes spent £46,000 installing the 25m-high tower 18
months ago and says he is having great difficulty having the
problem resolved.

The Department of Agriculture, which gave him a £15,000
grant for the turbine, said there have been "difficulties"
with 10 other turbines.

"It was three days after the turbine was installed that it
[the incident] happened," said Mr Hayes.

"It was really the first day there had been any real wind
since it had been set up. The wind got up and the rotors
came off the tower."

The blades, which have a diameter of 10m, flew off and the
tail went spinning in the wind.

Whats this diameter?. Do they mean length? or width? (10m, unlikely).
or is it the circle described by the blades as they turn. Anyway, not what
I would like to see.
