1. Come visit drdino.com’s multimedia section for long ages & evolution-bashing info. subscribe 2 mii pliiase :)

   intro: there is no unambiguous evidence which proves star formation is taking place: just because dust gets blown in certain directions, doesn’t mean it collapses into a new star!!! dust just clears from one area and goes to the next and a star which is ALREADY THERE is now exposed when it was previously hidden by dust!!! but u don’t see that explanation in textbooks … drdino.com

2. @ecotricity Don’t get me wrong, I am all for turbines everywhere they can be built. But at least here in the States, we don’t have battery/electric operated heavy equipment. The technology for that has existed for a very long time, but they are just not being produced. What I am saying is that we should build as many of these as we can NOW, while it’s cheaper. This type of electric construction equipment will come with a premium price, like any new product.

3. @WockneysRedBarrel No it’s not like saying those things atall. It’s simple enough – no need for bogus analogies: You’d need to erect 1200 turbines a day to counteract the growth in CO2 emissions from Asia.

   This is the point you need to address. Not some bogus strawman point you just made up because you don’t like the actual facts & figures.

   The UK gov are wasting billions of taxpayers money on these things – money that could be spent on schools, hospitals or medical research.

   Peace

4. @MMGWsceptic On your point, that these 3 turbines will make no difference to UK/global total CO2 emissions, this is like saying.

   “Don’t bother fixing the pothole in the road outside my house, there’s millions more on other roads elsewhere”.
   “Close the local school, its only one of many tens of thousands in the UK”.
   “Doesn’t matter if I run someone over and kill them, because that life is only of many thousands that are lost on the roads each year”.

5. @bodybager – For a 2MW turbine operating for 20 years “the energy use is paid back in 0.40 year [146 days], or 2% of a 20 year lifetime”.

   – “During its lifetime, the wind turbine [2MW, operating for 20 years] allows us to recover nearly 31 times the environmental contamination caused by its manufacture, start-up, operation and decommissioning.

6. I invented a breakthrough source of energy, which contradicts the law of conservation of energy. I have a PROOF that there are electrodynamic phenomena which contradict the law of energy conservation. It will cost about $1200 to make a 6 kW generator in mass production. Value of the energy produced yearly about $5400. I am looking for $300 000 for a prototype and for $3M for patents.

8. @SmallWindTurbines

   if you have a small rooftop windturbine, you need a battery and an inverter, you loose at least 20% of the electricity you produce. and batteries are really expensive
   big wind farms produce cheaper electricity than small rooftop wind turbines

9. It’s an artful; presentation, nice work. Who did the editing?

10. And you are planning to build 14 of these things near us at westhunspill?
    Made / installed / operated by non u/k jobs?
    Only operate at 30% of rated output?
    Devaluing homes wherever they grow?
    Once there ,open the gates for more?
    Never recoup the cost and energy of what it cost to build them?
    Cost per unit –turbine / against nuke?
    I hope you are building your next batch to place out to sea or on some desolate moor somewhere where there are no people to abuse?

11. What a giant waste of manpower and resources. 7% of all the electricity is lost in transmission. Wasteful. The same raw materials and labor should go to putting smaller rooftop wind turbines at the point of use. Then the 7% for the life of the equipment will be saved, used. Look at my videos of wind power, it’s a far better approach than these big wind farms. Then there’s all the copper it takes to carry the power from some remote location. Peace.

12. So to put it another way, you’d need to erect 450,000 of these turbines each year just to counteract the annual growth in CO2 emissions. That’s 1200 per day.

    This is neither physically possible nor economically viable.

13. Total energy per yr = 6MW x 20% avg output x 365 days x 24 hrs = 10512 MWhrs

    CO2 saving = 10,512 MWHr x 0.7 tons of CO2 / MWHr for coal = 6400 tons of CO2.

    Note: This only translates into a real saving if the standby backup generation is CO2 free (eg. hydroelectric or nuclear)

    Total global est man-made CO2 emissions = 3×10^10 tons / yr. The UK emits 2% of this.

    So these 3 turbines will save 0.001% of UK & 0.00002% of global emissions which are growing at 3% / yr as China & India grow

14. Just to clarify: These turbines produce 2MW each when the wind is blowing at optimum speed. However average output over the year is only 20% due to wind speed variation. At times the output will fall to zero when the wind is too weak or too strong. So standby conventional generation is needed for these periods greatly increasing the cost and reducing CO2 savings.

15. Look at “Rare Earth Mineral Mining in China” on Youtube

16. what song is this

17. Look , if you guys think wind power sucks like hell, there’s other thing like water power or geometrical power. Anyway this renewable energies saves tons of money. So either say shit about this wind power and protest outside the government buildings of US while getting a high bill OR let Earth live longer and get CHEAPER bills. But GREAT VIDEO!

18. Wind energy. If we took 1 tillion dollars the cost of the wars in you know where. 1 trillion/4 million (estimated cost of scale for a commercial one wind turbine) would net 25 billion wind turbines. One wind turbine can generate 2.5MWh electricity. 2.5MWh can power 350 homes in a northern cold state. 25 billion X 250 homes? I think that pretty much covers the US needs for power. Just having fun here, don’t shoot the messenger.

19. design and build for increased energy efficiency

20. Immigration? Dude if you aren’t an American Indian, you are an immigrant or a descendant thereof. If it wasn’t for immigration, there wouldn’t be a United States, Merry Christmas.

21. wow there are some weird oppinions here…..
    anti wind energy? wtf?

22. I think the best way to reduce carbon emissions in the west is to have an immigration moratorium. Statistics clearlyu show the USA population grew by 100 million in the last 40 years and nearly all the growth was due to immigration.
    The west could drasically reduce carbon emissions with a reduction in immigration and population and would have nearly stable growth in the USA with a moratorium on immigration.

23. u obviously know nothing about wind energy huh. the ones i just finished building were Vestas 3.5MW in Iowa. 62 of them can power about 50,000 homes and are expected to last 20-30 years.

24. This is just a hippy dream. The only serious energy is from coal and oil. It is harsh, I know.

    The wind energy is not viable.

25. I think what they mean is all 3 units combined produce 15 million kilowatt hours….

26. Free Energy is real and its here! The Oil companies are doing everything they can to stop this

    information. If you want a Free energy machine , get the blueprints at LT-MAGNET-MOTORdotCOM , Join the

    revolution!

27. I looked into becoming a distributor for these turbines. But a word to the wise, look at the power curve for this turbine, it took me asking about 20 times to get it. No wonder they were so reluctant to let it go, the 2kW model does start producing power in 5 mph wind. The problem is that it only produces the 2kW rated power in winds that are over 45mph. Where in the US does the wind consistently blow at more than 45 mph. When I asked the company, the response was the Bering straight.

28. @devonthemaster10 Dude, what are you smoking? Now wind energy is going to cause global warming??? what a frickin moron.

29. @kint909 some windturbine are noisy when in action….

30. @vox1philippines WHAT about the noise?

31. Put the things along the interstate and let traffic pay your light bills.

32. Seems like it would have reliability problems due to pressure constantly alternating between the top and bottom of the sail. Also, bearing pressure seems uneven. Anyone have experience with these?

34. how much is it

35. HOW about the noise?

36. who cares if a few birds get smoked? If we don’t address global warming then the birds and all other animals are going to be a lot worse off.

37. Yeah, the Savonius. Who knows, maybe some interest if you optimize the aero characterisitics. BTW, why is the video speeded up when you see the unit at high rpm (just look at the clouds in the sky scuttling about like Concorde) ?

38. That should be functional in a way that one could morf the area, so at night time that could be huge. :)

39. How much are they? Can they be purchased in or near Ohio?

40. Very exciting. Are you hiring? I would love to learn how to install these exciting wind turbines.

41. It looks like a piece of modern art.. to boot…

42. ow much duz eet cost to bye wung?

43. What are the blades made of? Fiberglass? If warped or damaged the bearings won’t last. Is there a censor for balance?

44. Half! I want a paycheck from the power company!

45. @devonthemaster10 Whats wrong with global warming? Is it wrong to avoid freezing to death?

46. @texme wind turbine not windmill

47. @dusteroo There were two units installed at the green man, burning man event of 2007.

48. ok,wind energy is not the answer the air flow of the earth is a vital key to life ,so in fact we may make global warming worse

49. have you thought of incorporating a maglev type frictionless bearing?

50. nice. color it with rainbow colors :)
