The answer is simple. It was a failuire of the governor. Resulted in
overspeed. One blade failed due to exceeding stress limit. Unbalance
caused remainder of problem. The governor failure was mentioned
somewhere in one of the shows.
No need to go into any "conspiracy theories" simple engineering
explanations cover it.
Most interesting, as we have had 230-odd Vestas turbines in operation
here in McLean County, Illinois for about three years. Several hundred
more turbines are scheduled for building in the next few years here
and in nearby counties. I noted propeller blade replacement being done
on one recently. Occasionally, a unit will be stopped for some
maintenance while all the surrounding ones keep ponderously rotating,
making volts and amps for Ransley up there in Chicago. I haven't seen
any bird kill problems, but there have been reports of a few bat
kills. At night, seeing acres and acres of winking red warning lights
impresses visitors. Kind of neat. The farmers like having the lease
income from the operation, and the construction crews were and are
absolute models of efficiency and care for the terrain. Not much in
the way of downsides.
They were supposed to build a fairly large windfarm here in one of the
few places where it would make sense. There is a high end development
located around 5 miles from there. A few influential people were very
vocal about how it would destroy their "view" so they had the zoning
regulations changed to prevent windmills without explicitly preventing
them. The interesting part too is the windfarm was being built with
private money not with money the government picked out of our pockets.
NIMBY strilkes again. Stuff like that is one of the reasons they are now
talking about building them offshore, in areas with both wind, and out
of view of tourist beachs and rich folk cliffs. Oh yeah, that'll make
them cheaper and more resistant to weather.
Nimby is being rammed up the rear of the only two complainers in this
county. Lacking any other reasonable argument (they tried all of them
and got shot down by science) they are using "low frequency sound" as
their objection now. County dads just _reduced_ the setbacks and
distance between towers in the local zoning. They had it at 5 times
tower height until it was pointedout that was far stricter than
anyplace else in the state.
Is there a problem with "low freuency noise" or it is just another
hoggoblin teh nimbys dreamed up?
There have been some very interesting programs on about the
development of acoustic weapons. It was on The Military channel
if I remember correctly. Back when I was a damn hippie freak,
attending loud concerts, I had some bone rattling experiences
from the large acoustic transducers in front of the stage. It's
funny how our military uses that same music to torture man
caused disaster suspects. *snicker*
"Application: Commercial application for parabolic speaker system are
listed as spaces like Airports, Shopping Malls and stadiums. They are
also used in by the police in situation like crowd control, hostage
crisis, anywhere where long throw intelligable audio is required."
I wish I could find one I could just stand to be around.
They all remind me of my mother, who is completely bonkers!
These days it's illegal to slap them upside the head in a
vain attempt to reboot their brain. *snicker*
