    r u in drugs man?

    well, because of the fairly high speed of the blades, relative to windspeed (speed of tips here idk 4-6 times windspeed i guess) all air travelling through the rotor will pass a blade atleast within say 0.2 bladelength, or 10% the rotordiameter,
    if my brain serves me right ;p which aerodynamically is quite close.
    the 3 blade design is a nice tradeoff between material cost, smoothness of power, noisyness, effectiveness, durability, operating envelope, etc.

    People who don’t work in the utility business have no understanding of how the grid works. Generation has to almost exactly match demand 24/7/365. If demand exceeds generation, you have blackouts. If generation exceeds demand, you have overload which usually leads to blackouts. That means sources of generation must be close to 100% controllable by man. Wind is 0% controllable by man, therefore it needs conventional backup 24/7/365 which then increases pollution.

    Comprende?

    you, are an idiot

    I now realize where all this wind is coming from. It’s these Giant Fans going up everywhere!! I bet it’s these commie-alqada terrorists! They turn these fans on “High” and blow up some wind storms, tornados and hurricanes. Now that America has a muslim “green” president….he gonna blow the USA clean off the Earth!!!!

    the design of that 3 fin wind turbine seems like its not taking full advantage of the wind , where as other designs would

    Way back in 1894, a little girl named Madeline Crothe was skipping through the woods when a mysterious man in black snatched her. He brought her to his house, tourtered her, and starved her to death. Send this to 6 videos in the next 30 min. and you will be safe, but if you don’t… at approximately 1: 34 tonight you will wake up to see an aneorexic child holding a bloodied up knife and she will kill you

    Wow! I would love to go to that school! Just think, it even adds to the learning experience. They can just walk outside for a field trip to learn about wind energy! Wind energy is not about global warming. It’s about using something that can never go away…There shall never be a day when wind is used up. Besides, you aren’t going to put a wind farm in a place where there’s no wind. You’re always going to use it where it can work best – in places where the wind is almost always blowing.

    I think these wind turbines look like abstract art on the landscape. They fascinate me :)

  11. HoosierHokie says:

    Why do anti-global warming people seem so angry about alternative energy sources? Is anyone really saying that windmills are being designed to provide 100% of our energy needs? No. How is providing alternative energy sources ruining our country?

    And please don’t tell me that you believe that windmills create more pollution than burning fossil fuels. I’m sure I must have misread that.

  12. futuremodal says:

    Electricity needs to be available AND CONTROLABLE 24/7/365. Because of that irrefutable fact, wind power is completely worthless by itself. The dirty little secret is that all wind power has to be backed up by conventional power, usually natural gas. Wind power is a waste of capital, and because of the need for perpetual backup, actually adds to pollution. This is just another example of why the global warming hoax is ruining our country.

    Wind power can be a good deal. Where I live, the power company has to buy back the power that you generate from wind turbines.

    Bravo Bravo ^^

    More renewable energy the better. I think they should look into water, it is pretty important.

    hell ya guy under me

  18. BinkieMcFartnuggets says:

    They wanted to cash in on what Iowa had a lot of. There was no way to really harness boredom so they went with wind.

    SLIPKNOT Hometown lol nice

    TYPE THIS ON YOUTUBE:”Al Gore sued by over 30.000 Scientists for fraud / John Coleman” DISCOVER THE TRUTH ABOUT GLOBAL WARMING!

  21. Zackerybob says:

    i don’t know about that but you miss the big picture here: this is the future of energy, whether you like it or not. Oil is running out and we need to find renewable ways of energy and all you complain and think about is how much it cost to install these things??

  22. scwallac says:

    Can you tell me which part of the video states that the school district spent any of their own money on this? I guarantee you this was some sort of gov’t grant or corporate donation.

    no, nuclear is the future

  24. JuciestPineapple says:

    Imagine having a seat on one of the tips of the windmills! Yay!

    it looks like you need to do some research into how much energy it takes to mine and refine the uranium needed to create a nuclear reactor not to mention the chances of a Chernobyl again
