1. Are non workers allowed to go up on wind turbines? I would love to go up
   one.

2. is it pronounced “turbine” or “turbin”? because i say “turbine”

3. I’d like to ask a question. If you have 50 turbines on a hill, all feeding
   into the grid, then they must all be kept in phase, which involves
   controlling the speed of the generator with phenomenal accuracy. I have
   often wondered – how is it done?
   With roof-top solar cells, it can be done with electronics, but I don’t
   know of any semiconductors that can handle gigawatts or even megawatts.

4. Makes me feel proud that I helped weld together many of these wind towers 

5. I’m not anti-wind power but facts are stubborn things. Wind turbines are
   not near as green as one might think. ALL energy sources impact the
   environment. There is between 6,000 to 10,000 lbs of copper in each
   turbine. Copper, like all the steel and cast-iron has to be mined,
   smelted, etc. Those gears and bearings must be lubricated too: There is
   about 80 gallons of oil in the gearbox alone. This must be changed every
   18 months to 3 years.
   Most importantly, there is between 752-800 lbs of rare earth minerals
   (mainly Neodymium and Dysprosium) used in the magnets. Almost all these
   minerals come China, which is not known as the bastion of clean
   manufacturing. This is for ONE turbine. Turbines make people feel nice
   and fuzzy “green” but reality trumps feelings.

6. Hi everyone. I want to know something.
   I want to design 10 wind turbines with 5KW each one. So that can give 50KW.
   Those 10 small wind turbines are a wind farm?. Or it’s just a wind energy
   system?

7. wwwww

8. how much wind turbines are standing in the USA?
   In Germany its over 25.000

9. Work on it and i can say, it’s amazing

10. I wish we found a cheaper way to build those things :)

11. It always amazes me how big those turbines are…

12. My handsome fiancé does this’ he’s actually in Texas at the moment 

13. sweet cool

14. Wind turbines generate DC voltage. No need to keep in phase. The DC is
    converted to AC when it is connected to the grid, using the grids’ phase
    for matching.

17. Great vid. Thx for sharing. Really captures the scale of the technology.

18. These wind farms you Green Liberals are shrieking about? Yeah, they’re
    killing scores of protected bird species, and Obama is having a ruling
    drafted to protect wind farms from any kind of penalties for any endangered
    birds that get killed. So at last we have the proof I’ve craved that you
    Leftists really do not give two shits about the earth or nature. You care
    about your little socialist agendas, but don’t worry: the best way to
    destroy a movement is to let it get strong, and since 2008 you Lefties have
    peaked. Hear that creaking noise? It’s your house of cards fixing to fall.

19. Just started working on my first turbine project last night with Mortenson
    Cons., stabbing the blades unto the hubs. I loved it!

20. You’re right. I don’t live near a wind farm. Traveled through some areas
    with wind farms, but apparently, you know more about them. Educate us,
    please!!

21. Wow that’s crazy awesome

22. For a recent (days ago) beautiful evening low flight over several hundred
    big, hard-working turbines, go to my channel and click on “Breaking Wind at
    the Rio Vista Wind Farm.”

23. That’s an Anemometer en.wikipedia(dot org)/wiki/Anemometer

24. 1:00 mute this and play Metal Gear Solid 3: Snake Eater – Song.

25. Is 1.8MW the installed capacity? What is the Capacity factor for these?

26. I have a give away contest going right now, FREE wind turbine and solar
    panel, here’s the link Free Wind Turbine Solar Panel Free Give away contest

27. Awesome video! Do you need a rectifier for EACH wind turbine or other
    device that’s hooked up? If so, do they all get wired in series with the
    charge controller ?

28. Wind turbines for the beginner How to part one by Missouri Wind and Solar

29. Great “How To” video Jeff !!!! Really opened my eyes to some new energy
    sources !
    I hope you know how important you sharing your knowledge and experience is
    to other “Utubers” !!
    Salute !!

30. I like your efforts on keeping us informed. I live in Casper Wyoming and we
    have an average of 12 mph, and often up to 35 to 45 mph, what would you
    recommend in windmill for an area that can and will have high winds?

31. Excellent video Jeff, very informative. Thanks for doing these video’s
    with all the practical and logical information for everyone to use!

32. will these work

33. Is that just a regular alternator? and can I fabricate the same deal with a
    rebuilt gear box?

34. nice presentation. just 1 question. your 300 watt wind turbin can charged
    600 amps 12 volt battery? 

35. excellent

36. Sir, thank you for this information! What solution can you give me about
    lightning conditions? Blessings from windy Cape Town ~ South Africa

37. Hi Jeff one of the best video’s to-date on the use. of Wind turbines and
    solar 

38. very instructive video.
    just the thing that i’m not sure about is about the output voltage entering
    the rectifier, is it constant or shouldn’t be there some device to regulate
    it to 12 v ?

39. FANTASTIC VIDEO!!! (,,,the content is so good that the sound trouble at the
    end is totally forgivable) Thank you very much for making this video!

40. Thank you. The first 5 minutes of this video saved me at least $100. I
    have been battling with wire running to my charge controller.. did not know
    that solid copper was a no-no.. even went with the heavier wire as wire
    gauge chart says it should handle my amps.. but only showing half of what
    should be there.. so i’ll be going with wire strand.. thanks again =]

41. What keeps the wires coming off the win turbine from twisting if the
    rotates too many times in one direction? Are there stops with the mounts
    or something?

42. Man, the best piece of info ever in the whole net. I had 2 days trying to
    understand the system until I landed here. Greetings from Panama.
    * loved it when you hooked up that radio something like KSHE 95
    came on…ha! 

43. Do you have constant speed bladed wind turbines? 

44. Can you use house wire on a ac wind turbine?

45. Is there any kind of material you can make blades out of that will rest in
    a large pitch but flatten out to a slight pitch at higher RPMs? I know this
    is probably a dumb question but I thought it was worth asking.

46. Im making a wind system in my home country and i was wonder where can i
    get the main items for the control system and can i get some links

47. I looked all over yotude, there is not one video’s on hooking up a 3 phase
    grid tie inverter, the plug and play ones, can you make one?

48. awesome video what about VAWT?

49. I know quite a bit about them myself – which is how I can tell you aren’t
    full of marketing BS! – I wouldn’t mind trying to build a working version,
    of my own wind turbine design called a “Wind Engine” (search for you-tube
    video of a mock-up working model I built). Take a look at it and let me
    know what you think.

50. all electricity flows on the surface of the wire. therefore stranded wire
    has vastly more surface area and so can carry more amperage AC or DC it
    doesn’t matter. more surface equals more amperage. For prof of this concept
    look to super high amperage cable they always have super fine stranded
    threads ie welding cable. Everyone should consider never using single
    strand AKA solid wire on anything ever ever ever.
    Looking at the death toll for romex wired houses should convince even the
    most skeptical
