Are EVs a Fire Risk?

A relative was recently considering an EV when a neighbor suggested if they did buy an EV not to park it in the garage. Left unsaid was why. Similarly his Fox watching sister said if he did buy an EV he better install a smoke detector in the garage. Again, …

DAF-Indal: The Canadian Darrieus

DAF-Indal[1] began working with Canada’s National Research Council and provincial utilities to develop Darrieus wind turbines using Canada’s abundant aluminum in the mid 1970s.[2] They constructed about a dozen small prototype Darrieus turbines less than 5 meters in diameter and about 9 meters tall in the mid to late 1970s, rated variously from 4 kW to 12 kW.[3] One was installed in the Arctic for Canada’s Defence Research Establishment.[4] Another was installed in Texas at the USDA’s Bushland Experiment Station in a wind-assisted pumping test. Another was installed on Block Island, Rhode Island.[5] One was still standing—inoperative–outside Toronto in 2007.[6]

Floating wind could power UK to net zero

In sum, around three-quarters of the technical potential for offshore wind involves floating offshore wind farms. Indeed, all offshore wind, both floating and fixed-bottom, could provide more than 2100 TWh of UK electricity (see HERE). This is much more than the UK will ever need to meet net-zero greenhouse gas policy objectives, or indeed any other policy objectives.

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.

Man Falls to Death from E66 in Germany

By

Paul Gipe

On October 16, 2003 a 25-year old technician fell inside a 100-meter tall Enercon E66 tower, struck his head, and died according to an account in a local German newspaper. The man, unnamed in the Prinzitger Zeitung article, was performing warranty service on a ladder when he fell.

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.

Failed Dream: the Bearingless Wind Turbine Rotor of the Late 1970s

By

Paul Gipe

On paper the composite bearingless rotor seemed too good to be true: a wind turbine rotor that enabled the blades to change pitch without bearings in the hub. And the wind turbine would passively use aerodynamic forces to orient the rotor downwind of the tower. It was the height of simplicity and would be cheap to build. What could go wrong? The short answer: everything. Eventually the nearly 400 wind turbines using the concept in California during the Great California Wind Rush of the early to mid 1980s were scraped off the face of the earth for scrap. And therein lays a sprawling tale.

NREL’s Wild West of Wind: a Glimpse of California’s Past

By

Paul Gipe

While interviewing Brian Smith about his early career during the Great California Wind Rush, he mentioned that NREL had done a retrospective on the history of the lab. Specifically, he suggested I take a look at the chapter titled the Wild West of Wind. Yee ha! Brian was right. He and Walt Musial have some great tales in that chapter. If you weren’t working in California’s wind industry then and you want a flavor of what it was like, take a look. The title is a pretty accurate summary of the times.

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.
  • Dutch Windmill and Watermill Database–Working historic windmills and watermills of the Netherlands with a searchable database and interactive map. The map identifies individual windmills and when they are open to visitors. The home page is in English, map data is in Dutch but understandable to English-speakers.
  • La route des moulins–Interactive map and list of windmills and watermills by region with a description of the specific mill in French. Includes a description of the Centre Molinologique.
  • Deutsche Gesellschaft für Mühlenkunde und Mühlenerhaltung–The German society for the preservation of wind and water mills. They too have an interactive map of the mills throughout the country. The map can be searched by town, village, or state. The detailed data includes the type of mill and its construction.

Other Open-Air Museums
