Pintles, Kingpins, & Slewing Rings: The Evolution of Yaw

While researching material for an article on the 100 kW Soviet wind turbine at Balaklava, Etienne Rogier sent me an article with a cross section of the famous machine’s nacelle.[1] The cross section gives a rare glimpse into the workings of the machine and how it turned about the top …

Were there two wind turbines tested on South Barrule on the Isle of Man in the early 1960s, not just one? That’s the inescapable conclusion from photos that have recently come to light. During research for an article on the development of the modern wind turbine, (see History of Conventional …

Thirty years after its publication by John Wiley & Sons, I’ve put Wind Energy Comes of Age in the public domain. The digital copy of the more than 500-page book is now open access and is available for reading on line or it can be downloaded in its entirety for free. You can find the open access digital version here: Wind energy comes of age by Paul Gipe. Print copies can still be found at used bookstores or in university libraries.

A question arose from the international wind community about a photo on the late Peter Banner’s web site. This is a photo of five of the six Maetecnic turbines on the Sandberg site in the Whitewater Wash from Banner’s web site (http://scientiaenergy.com/) that he labeled “Guengrich wind turbine.” I didn’t …

Dismantling a wind farm: all the details of a real case

The dismantling of the Muel wind farm demonstrates that circularity in wind energy is already an industrial reality. The results, with an outstanding 99.85% of materials recovered or recycled, confirm that recycling or recovering nearly 100% of a turbine is not science fiction, but the outcome of applying engineering, collaboration, and technical knowledge. The next step for the industry will be to make it faster, more cost-effective, and with greater added value in each material flow, consolidating circular economy as a standard practice in future repowering projects.

Europe should seek constructive cooperation with China on energy policy. Even though the two regions are developing very differently in socio-political terms, cooperation in the field of energy and climate policy offers enormous opportunities for the whole world. Europe and China can play a key role in the global energy transformation and in the global fight against climate change by using their resources for this purpose. This naturally requires constructive dialogue on an equal footing, in which both blocs formulate their own and shared interests and develop their relations on a clear basis. This also means that Europe and China can and should work together to convince numerous other countries that the path of renewable energies is the path to a good future for all people, a prosperous and more peaceful world that successfully overcomes the climate crisis.

Accidents & Safety

I’ve been concerned about safely working with wind energy since 1976 when I nearly killed myself taking down a 1930s-era windcharger. While wind energy is an environmentally beneficial technology–and that’s the reason we need to use it–it can and has killed. Consequently, I’ve been tracking fatal accidents in wind energy since I wrote an obituary for a colleague, Terry Mehrkam, in 1981. For this reason, my books on wind energy have always included a section on safety.

Documents Detail Harrowing Attempts to Save Chehalis Man at Wind Project Site

By

Eric Schwartz

When a trench partially collapsed on a coworker at the Skookumchuck Wind Project outside of Rainier on the morning of Thursday, Jan. 9, 24-year-old Chehalis man Jonathan Stringer didn’t hesitate. He jumped in the hole with another worker and began attempting to save his buried colleague by digging out dirt and rocks with his bare hands. That’s when another collapse completely buried Stringer, prompting a harrowing ordeal during which about 25 other workers tried in frantic shifts to save him, but ultimately failed to reach him in time.

Tower Climbing Safety

Safety

In 2013 I pulled together some links to documents on safety relative to the wind industry. These topics went beyond simply tower climbing safety and safety at height and included work around rotating machinery and other common industrial hazards. Unfortunately, the industry has changed dramatically in the past decade. Most safety documents once freely available are now securely hidden by paywalls. Moreover, even the wind energy trade associations where these documents were once located have ceased to exist, merging with other renewable trade associations. Some of the British documents are still available and I’ve provide links to them. I found one public document on the off shore industry in the USA.

Films and Videos of Historic Wind Turbines from 1925 to the Present

By

Paul Gipe

I’ve uploaded a series of films on historic wind turbines in operation to the Internet Archive. To help me keep track of them, I’ve posted the links and a short summary here. I’ve included some films in this list that are on YouTube.com as the provenance isn’t clear. Of course videos of operating wind turbines are quite common now, so I am limiting this list to those of historic interest.

Text of “Motion Picture History of the Erection and Operation of the Smith-Putnam Wind Generator” by Carl Wilcox

By

Paul Gipe

The following was a question and answer session with Carl Wilcox during the 1973 Wind Energy Conversion Systems Workshop in Washington, DC.[1] Wilcox had been a member of the Smith-Putnam team.[2] Beauchamp Smith of the S. Morgan Smith Company also attended the conference and gave a presentation just before Mr Wilcox. The “COMMENT” below was likely by him as he addressed Mr. Wilcox as “Carl.”[3] There were other luminaries at this conference, including Ulrich Hütter,[4] Jean-Marc Noël,[5] and William (Bill) Heronemus.[6]

The annals of wind energy are filled with examples of arrogance, hubris, and hype about products that failed to deliver on their promoter’s promise. One long forgotten example is the Schachle wind turbine. However, unlike the Internet wonders that bedevil us today, the Schachle wind turbine was a real piece of hardware not merely electrons floating in the ether.

Lassoing a Runaway Windmill

By

Paul Gipe

It was common knowledge on California wind farms in the 1980s that one way to stop the rotor from spinning out of control was to somehow get a rope tangled in the rotor. The rotor would then wind up the rope, wrapping it tightly around the main shaft, slowing the rotor if not stopping it. To get the rope into the rotor, it was necessary to shoot an arrow towards the rotor with a line attached. If successful, the spinning rotor would do the rest.

Museums with Wind Exhibits

Museums often have extensive permanent collections and only display a small portion at any one time. Museums frequently change their exhibits and that is the case below. The museums noted here have all changed their exhibits since I last visited. Some have created “virtual” exhibits, and these I’ve noted.

North American Open-Air Museums

European Open-Air Museums

There’s nothing like walking among the operating windmills of Zaanse Schaans in the Zaan district of Noord Holland, or strolling among the vertically-jutting blade sculpture at the Folkecenter for Renewable Energy in Denmark to gain a sense of the importance of wind in European–and thus Western–culture. For the avid wind aficionado and the scholar alike, I strongly suggest putting one of the many open-air museums in Europe on your travel itinerary. Some we discovered by serendipity others we searched out. All were worth the effort.

Note that in most western European countries there are national “windmill” days where many of the historical windmills are open to the public. Many now include some modern wind turbines as well. Often the national windmill day is the second Saturday in May though this may vary by country. In Germany, Deutscher Mühlentag is held on Whit Monday or Pfingstmontag in German. In 2023 Whit Monday was 29 May.

  • Museum Park, Deutsches Technikmuseum Berlin, Germany displays a historic stage mill, a mechanical farm windmill, and a micro wind turbine.
  • Schloss Sanssouci Berlin displays a reconstructed stage or gallery windmill that has served the palace (Schloss) since 1787. It was a mill on this site that served in the famous legend of the Miller of Sanssouci who challenged kingly power.
  • Windmill Blade Expo at the Folkecenter for Renewable Energy in Jutland, Denmark.
  • Showroom for historical Danish wind turbines at the Folkecenter for Renewable Energy in Jutland, Denmark–An extensive collection of wind turbine drive trains from the early days of Danish wind power.
  • Poul la Cour Museum–The museum is situated in the historical buildings where Poul la Cour, affectionately called the Danish Edison by Danes, conducted his research into wind energy and hydrogen storage. The site is the cradle of modern wind energy.
  • Energimuseet Vindkraft–The museums’ open-air exhibits include the original nacelle from the famed Gedser mill designed by Johannes Juul, an erect Riisager machine from the rebirth of Danish wind energy in the late 1970s-early 1980s, a cut-away wind turbine blade and more.
  • Frilandsmuseet–The Open Air Museum north of Copenhagen is one of the largest and oldest in the world. Spread across 86 acres of land the museum houses more than 50 farms, mills and houses from the period 1650-1950.
  • Museummolen Schermerhorn–Open air museum of the polder mill on the Schermer polder in Noord Holland (north of Amsterdam).
  • Germania (molen)–Platform grain grinding mill in the province of Groningen, the Netherlands. One of the more than 1,000 windmills in the Netherlands that are periodically open to the public.
  • Internationales Muhlenmuseum–in Gifhorn, Niedersachsen, Germany has 13 different windmills on display, including a Greek sail windmill.
  • World Heritage Site of Kinderdijk–The nineteen windmills of Kinderdijk illustrate the way the Dutch have used windmills to drain the polders that have made the Netherlands what it is today. Kinderdijk is most likely the world’s oldest wind farm and was in use into the 1950s.
  • De Vereniging Zaanse Molen–No tourist trip to the Netherlands is complete without a visit to Zaanse Schans and the working windmills of the Zaan district. The Society of Zaan Mills was founded in 1925, beginning with the restoration of the oil mill De Zoeker. Three years later, they opened the Mill Museum at Zaanse Schans. Now, nearly a century later, the Society possesses 12 industrial windmills, representing an important part of Dutch cultural heritage and to this day still define the Zaan skyline.
  • Museumdorf Cloppenburg is south of Oldenburg in Niedersachsen, Germany.
  • Nederlands Openluchtmuseum–Open Air Museum in Arnhem, Gelderland, the Netherlands.
  • Mola – het Provinciaal Molencentrum–East Flanders windmill museum in Belgium with four restored windmills.
  • Wind Energy Museum Norfolk Great Britain–The museum is closed in 2023. The collection depicts the evolution of polder drainage in what’s called the “Broads.” The technology for the mills and how to use them was imported from the Netherlands.
  • Deutsches Windkraftmuseum–Begun in 1997, the museum seeks to preserve some of the early electricity-generating wind turbines from the 1980s and 1990s in northern Germany. While the exhibits focus on German development of wind technology, the museum includes a Lagerwey, an early Dutch machine, early Danish wind turbines, and some American-made wind turbines as well, including a Kenetech drive train and a Bergey small wind turbine.
  • Allemolens.NL–Web site listing the location of every windmill in the Netherlands from the smallest mechanical wind pump to the giant polder draining windmills and to the multi-story stage windmills for grinding grain. They even include a few modern wind turbines as well. In Dutch.

More on Fayette Manufacturing and its One-Time Resurrection

By

Paul Gipe

While archiving articles I’d written for the American Wind Energy Association’s newsletter, Wind Energy Weekly, I came across this one about Fayette’s restructuring in 1990. At the time I was the west coast representative for AWEA in Tehachapi. There’s not a lot on my web site about Fayette. (I do mention them in my books and in articles on capacity factor and how this figure of merit can be so misleading.) Consequently, for historical reference I am posting the article with the original date that I submitted it to AWEA. See Fayette Reborn in Major Restructuring.
