2027 Chevy Bolt Odd Noise at Low Power Levels

Since receiving our 2027 Chevy Bolt 20 February, I’ve noticed an odd noise at low power levels, upon deceleration, or at neutral or zero power levels. I’ve been driving EVs for 12 years now and the noise is not a normal EV sound. It’s not the whine of the motor/generator, …

Dean Thomas, son of Robert Thomas, the designer of the Wind Harvest Vertical Axis Wind Turbine is still plugging away on the design. He’s built a 1/40-scale model of a guyed giromill. Based on published information, the optimum solidity for maximum efficiency is 16% so he’s using four blades, two …

I’ve previously written about the history of Wind Harvest’s Vertical Axis Wind Turbine from the mid 1970s. (See Wind Harvest VAWT—a Jungian Vision (the Backstory). Recently, Dean Thomas, the son of Wind Harvest’s founder Robert Thomas, contacted me with more on the history of the turbine’s development from someone who …

We drove to Los Angeles from Bakersfield to meet a friend for lunch Sunday. That may not sound like much to those driving a gasser or a long-range, big battery EV, but it’s significant to us. We drive a 2027 Chevy Bolt, the least expensive EV in the US. We …

It’s been one month since our 2027 Bolt was hand delivered. I am still working through the new driver’s interface and changes to the controls, but we’re using it. I’ve now driven more than 1,000 miles so I can report on actual and reported range, and the traction battery’s capacity. …

The New Geography Of Wind Power In Canada

Ontario’s return to renewable procurement is the clearest sign that one of Canada’s largest electricity markets has accepted a reality it spent years resisting. The timing is propitious as I prepare to provide an update to a global audience on North American wind energy through the World Wind Energy Association. Electricity demand is rising as transport, buildings, and industry electrify. Refusing wind and solar in that environment was never a long-term strategy. It was a pause wrapped in politics.

Whatever Happened To The Affordable Car?

Most of us have forgotten how the Big Three snookered the Obama administration into creating two classes of fuel economy standards — one for passenger cars and another for light trucks. In theory, the light truck provision was to benefit farmers who needed them to get their goods to market, but the automakers used that exception to create a whole new class of vehicles that were never intended to work for a living, The SUV originally was little more than a pickup truck with a passenger car body on top. The companies promised the Obamans they would use the bailouts offered them to build new fuel efficient small cars, but as soon as the ink was dry, they forgot all about those promises and went full tilt boogie into cranking out high end pickups and SUVs.

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.

Tower Work and Do-it-Yourselfers

By

Paul Gipe

Any wind turbine and tower that cannot be safely lowered to the ground for servicing should have a fall arresting system for ascending, descending, and working atop the tower, a sturdy work platform, and safe, clearly identifiable anchorage points for attaching your lanyard. No one should climb a tower of any type unless they’ve received training in tower safety. . .

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.

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.
