Wind power negatives

[emi_ula]

Hey,

I am environmental engineer (from Poland)and I am engaged in subject of mitigation of wind farms adverse impact on environment, which one of you realize of the hazard connected to wind turbines?? Have you heard of infrasound emissions or Vibroacoustic disease ????

[Mr.Whip]

Interesting topic. Did they ever come up with a (safe distance) from wind farms to avoid VAD. I'm sure with large windfarms those low frequency disturbance's travel miles. What info can you share with us???

Thanks Randy

Symptoms Frequency
General feeling of discomfort 4 Hz – 9 Hz
Head symptoms 13 Hz – 20 Hz
Influence on speech 13 Hz – 20 Hz
Lump in throat 12 Hz – 16 Hz
Chest pains 5 Hz – 7 Hz
Abdominal pains 4 Hz – 10 Hz
Urge to urinate 10 Hz – 18 Hz
Influence on breathing movements 4 Hz – 8 Hz

Most of researches on this case concludes that "if you cannot hear a sound, it does not affect you"- but my question is-how about UV - you can't see it but it affects you anyway .

There are some tests made on guinea pigs that respond (its ear's cochlea )to infrasounds at frequency below 10 Hz, yet guinea pig is considered to be less sensitive than human.

Human response to infrasounds is based on bending of sensory cells of inner ear due to vibrations, and the inner hair cells are connected to auditory nerve fibers that send signals to the brain.

Generally, most of the sound coming from turbines measurements are performed by A-weighting, which is based on human audibility curve, and as a matter of fact it does not represent infrasounds. G -weighting is another method that is more suitable.

I have always had the instinctual feeling that solar is the best way to go, as it seems very passive and noninvasive.

No offense to other methods but solar makes the most sense to me. I guess it does take up space but rooftops can be utilized.

I agree, solar, in my opinion, does not have any impact on environment ... It is least invasive.

Over the next 20 years better materials for air foils and transmissions and smoother controls and electronics for handling high levels of electrical power should become available.

Useless in large portions of U.S.

There is a large cost involved in wind farms, but more so in areas of the world where temperatures drop below freezing with regularity. Has anyone here seen the frozen wind farms up north right now? I wonder what these composite materials are going thru with all the weight of the ice hanging on those long blades? Will the cost of repairs negate the savings forseen as posible? Just some thoughts for now....

I was just sent this link by a friend. It seems odd that people would be against wind power as this site clearly is. Sure it's not perfect, but it is far more perfect than other methods of power generation in my opinion. Is there similar groups and North America and can someone explain to me why one would be so against wind...and don't say it's because they have stock in BP

A couple of things I've heard about are the birds that are killed by the blades and the amount of torque that make turbines mounted on buildings a problem for the structural integrity of the building. Also, engineers seem to think that the power generated by wind isn't concentrated enough to make it feasible as a replacement for fossil fuels.

Windy Hill Wind Farm - Wikipedia, the free encyclopedia

Windy hill is about an hour down the road from me. It's been providing over 3,500 homes with power for the last 11 years. We also get baseline backup from coal fired stations some 1000km south, but with windy hill and just two hydro plants )on one the barron river, one on the burdekin,) where I live we could be using 100% green power, 20% wind, 80% hydro. The fact we are not is due 100% to the fact the coal industry lobbys the state government to keep those coal fired stations burning coal and making them money, even though it's utter crap for the planet.

But hey, at least it makes rich people richer. Go fossil fuels, hey?

Bugger that. More wind and water turbines please.
