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.

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.

Another Long-Forgotten Wind Turbine–This Time on the Isle of Man

By

Paul Gipe

The research for an article on the history of early wind turbines took me down one fascinating rabbit hole after another. Previously, I mentioned Dimitri Stein and his Nordwind turbine on the Island of Neuwerk in the Wattensee. Another long-forgotten wind turbine I’d never heard of before was off the west coast of England on the Isle of Man.
