World’s oldest operating wind turbine turning 40

CleanTechnica

On May 30, the world’s oldest operating wind turbine will turn 40 years old. Tvindkraft was built in Denmark at the Tvind school in Jutland. Danish wind enthusiasts will join there again soon to celebrate the turbine’s 40th birthday.

Celebrating the birthday of a wind turbine might seem like a “snoozer” to some, but Tvindkraftwas a moment in energy history as well as something of a movement. “However, word spread in the Danish population — and also outside the country — about the mill project, and people flocked from near and far to give their opinion. Tvindkraft is an example of the place where people get together a vision, putting our heads together and put forces in, paving new roads.”

The 54-meter-high turbine has an iron and concrete tower and cone. Construction began in 1975 with teachers and volunteers, and a 1 MW turbine was installed and has been generating clean electricity for many years. Though perhaps at the time it was considered very difficult, it was a small group of people who got the job done. “How could they build what was then the world’s largest wind turbine—a machine that has operated for more than three decades and remains in service to this day—when Boeing, Westinghouse, General Electric, Hamilton Standard, Kaman, Messerschmidt-Bölkow-Blohm, MAN and others had all failed, their turbines dismantled and sold for scrap?”

They could achieve it because their motivation was much greater than profiteering. The Tvindkraft success contains purpose, and autonomy, though one might say mastery was also present. “In Drive, Pink goes on to illustrate why the traditional carrots-and-sticks paradigm of extrinsic reward and punishment doesn’t work, pointing instead to his trifecta of intrinsic motivators: Autonomy, or the desire to be self-directed; Mastery, or the itch to keep improving at something that’s important to us; and Purpose, the sense that what we do produces something transcendent or serves something meaningful beyond than ourselves.”

It is very impressive that there has been a wind turbine generating clean electricity for decades. Would any readers care to try to figure out how much it has produced over the decades and comment below?

A wind turbine in the US was actually installed over 100 years ago, and was coupled with battery storage. These stories show us what true initiative and dedication are.

    I wonder how much power this has produced in the 40 years?

    The answer from the home site producing 20,000,000 million kWh.

    and here is an ironic fact
    the main shaft came from a scraped oil tanker.

      There has to be a mistake on the website. It says annual yield is 1 mio. kWh, which is reasonable for an early 1 MW prototype so in forty years that would make 40 million kWh which is 0.04 TWh. 20,000,000 million kWh would be 20 TWh. I would think actual annual yield could be lower by half so that it should be 20,000,000 kWh and they mistakenly added a million too much. If the 20 TWh would be correct, the Tvindkraft would produce half a TWh a year, which would be 20 times more than todays 5 MW turbines, that produce 0.025 TWh a year. So another fun fact is that a modern wind turbine produces more electricity in one year (if it is 0.02 TWh and not the 0.04 TWh I calculated form the stated annual yield, then it would be two years) than this early handmade prototype produced in 40 years. They still pulled of an impressing prototype project, though.

    Happy Birthday Windy! I notice on their web page that the turbine is surrounded by buildings which I assume people work,study and/or live in. Meaning that people are in close and constant proximity with the turbine and have been for many years. Any evidence from them about the supposed ill-effects from exposure to operating wind turbines would be quite valuable. Not only are the people in close proximity to the turbine but some of them would have had years of exposure at the site. This could be an opportunity to finally dispel any doubts that Tony “Don Quixote” Abbott and Joe “Sancho Panza” Hockey seem to have about health effects from wind turbines. Then instead of wasting yet more taxpayers dollars on yet another Quixotic assault on wind turbines with yet another pointless inquiry, the money could be spent on a proper inquiry into the health, environmental and community effects of CSG mining.

      here is little about infrasound

      http://www.birds.cornell.edu/brp/elephant/cyclotis/language/infrasound.html
      Play the sound bites notice we as in you and I can not hear it that is not to say it does not have an effect however I do remember doing sound studies in the 1970 where the output of vehicle was both below and above a humans hearing level in fact the amount of infrasound in our environment is huge for instance wind through trees produce a huge level of sound in this area.

        I don’t get what you try to say with your comment. Study after study has been done about the infrasound generated by wind turbines and no effect on human health has been found whatsoever.

          Exactly onesecond
          Before we had blades in the wind no problem.
          In fact when I did my work the amount of infrasound in the background was a problem to try and find the amount of sound I was trying to measure.

            Ok, now I get it, thanks for clearing that up!

        Maybe they could make 6-blade turbines instead of 3 blade ones.

        The stealth submarines have 6 blade propellers to cut noise and avoid detection.

        The studies have been conducted by sound engineers but should be done by psychologists.

          How very true Alan it is so sad that perceived effects are born out in life.
          One may relate this to your life if you are fearful of getting sea sick guess what as soon as you get on a boat you get sick.
          Mind bad analogy because this is very well understood by the fact that middle ear rocking may result in the feeling of nauseousness.
          There is actually a very well understood term in the medical literature for perceived illness due to some outside effect.
          A simple word that comes to mind is the placebo effect.
          However this is the opposite in this case it is along these lines quote ” I am going to have some effects because of this mechanical intrusion into my life”
          As sure as the sun will come up tomorrow surprising these people have all these effects.
          I take note of your mention of Psychologists how very astute and I feel true.

      World’s clunkiest headline matches the turbine support tower. BTW, does J. Hockey’s hatred extend to Aus farmer’s iconic bore water pump windmill, could require another enquiry..those things squeak like crazy

    How many hundreds of millions of dollars has the Australian Government put into supporting the “roof-top” solar energy scheme.
    How much are we paying to support this “clean energy scam” on our quarterly electricity bill????

    Hi everyone – nice to see such an interest from down under!

    So I have some comments….

    Rob: I live and work in Tvind. I am a teacher and I work at the international youth college there. The biggest school on the campus is an international teacher training college. http://www.dnst-tvind.dk

    The windmill is about 100 metres from my office. We have not experienced any ill effects of living and working in such close proximity to a wind turbine. You get used to the gentle whistling from the blades in no time, pretty much like when you live next to the sea, the sound of waves cashing onto the shore doesn’t bother you after a while. I walk my dog around the tower several times a day. I have never come across a dead bird caused by the windmill. Some of us who live here are a bit weird, but I am sure that it is not caused by living close to the turbine, I am pretty sure we were like that already when we moved here. 🙂 I have been here for almost 20 years, and am still healthy and happy – you can tell Mr Abbott that.

    The only hazard I can think of is that the tower does attract bolts of lightning when there is a thunderstorm. The landscape around here is very flat. So, apart from a church tower a mile or so from here, and the neighbour’s silo, there are no tall buildings around. The tower and blades have taken a direct hit from time to time, and we have procedures for how to stop the windmill etc. when a thunderstorm is approaching.

    John: The turbine has been operational since March 1978, and has produced 20,5 mio kWh since then. 17,2 mil kWh as electricity – mainly for the schools at the campus, but also for the national grid – and 3,2 kWh as hot water for central heating of the schools.

    We also have solar panels on site and we aim for becoming 100% self sustainable with green power. Just need to find out how to store the electricity…

    Oh – and there’s a great song about the windmill, by singer / songwriter David Rovics…

    We’re throwing a big party on Saturday to celebrate…. Send us a greeting from down under 🙂

    Greetings,
