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
great and good here had some more practical / technical advice on what to be
looking out for first?
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.
Each blade was 16 ft (5m) long. The systems were built in China.
This evening's paper has a report about another man who had the
same problem.

Farmhouse horror as turbine blade smashes through roof
Wednesday, June 18, 2008
By Linda McKee
A farmer has described the shocking moment a 16-foot wind
turbine blade smashed through the roof of his home as his
family slept inside.
“It was like a bomb hitting the roof of the house. It
shattered the tiles and the blade disintegrated itself,”
David Campbell told the Belfast Telegraph.
The turbine was one of a batch of 11 defective machines
installed on farms in Northern Ireland with the help of
European funding provided by the Department of Agriculture.
All 11 of the Chinese-built turbines, sourced from the same
supplier, have broken down but the farmers have been left
thousands of pounds out of pocket and they complain that
no-one is doing anything to help.
Mr Campbell said the turbines, supplied by Co Tyrone company
Adman Building & Civil Engineering, were only operating
for a matter of hours before they broke down. He said his
turbine “took off of its own accord” one stormy night in
January 2007: “It got up momentum with the wind blowing. It
went for four hours until about 4am and the three blades
came off. One of the blades went through the roof of the
house — it cut through it like a chainsaw.
“If anybody had been in line of them when they came off,
they definitely would have been killed — the blades are 16
foot long.”
