Why do you consider them "terribly intimidating"? I agree they ARE huge... I mean, do you find tractor trailer trucks terribly intimidating? or airplanes? I mean those things actually kill people... They aren't stationary... and they're a heck of a lot louder than a windmill... Not to mention the pollution they create. And as for the noise... how many homes are built in and amongst the wind farms anyways? None that I've ever seen... Most wind farms are well away from large population centers/areas... Perhaps a farm house or two from the people leasing the land for the placement of them?
Sorry, I guess I just don't understand
People don't want global warming and complain about our dependence and overuse of fossil fuels, yet those same folks don't want and complain about harnessing wind power... Either they're "bird killers" or "eye sores" or in your case, too loud and intimidating... Maybe they'd be more acceptable if they looked more like the "little" Dutch windmills used for grinding grain and pumping out water? Most folks think they're "pretty". Folks think the Dutch ones are no threat because they're turning slow, I believe the modern windmills turn about the same speed... they're just bigger. Not to mention the screams and complaints when there are brow/black outs and there's no electricity to run their air conditioning or their TV sets. The power has to come from someplace.
Actually Deb, those aren't the longest blades or largest wind generators... Vestas makes much longer blades, in service since early 2014:
"The Vestas V164 came online in January 2014, nearly three years after the project ... Among its features, it includes the world's longest turbine blade at almost 85-metres." Started out at 80M... either way, 262-279' The Vestas plant right down the road from me builds these blades (and the generators/complete units). http://www.windpowermonthly.com/10-biggest-turbines
As an aside, the discussion really started out discussing vertical wind generators:
which aren't anywhere near as huge, don't take up anywhere near the amount of space, and don't make any more noise than the windmill type in my experience, which is minimal to begin with... The noise from the windmill type is simply a "whoosh" as the blade sweeps past over head... The generators 300' above your head make no noise at all... And the vertical ones make a very faint whirring sound, again simply from the wind moving through the vanes.
I suppose there could be a chance of resonating in the blades/vanes at a specific RPM... physically possible... it would cause a resonate "tone" or frequency that may or may not be audible, but that's one of the things tested for in development and designed out as it would put additional stress on the blades/vanes causing earlier failure of the system.
