Maine fishermen aim to sink Biden’s offshore wind farm plan

FOX Business’ Lydia Hu reports on President Biden’s wind farm plan opposed by Maine’s fisheries. New England Fishermen’s Stewardship founder Jerry Leeman explains how the plan poses a risk to marine life and the industry, saying ‘it’ll cripple us.’

The University of Maine is contributing to the global effort to improve floating machines to harness wind over deeper offshore waters.
Researchers envision turbine platforms floating in the ocean beyond the horizon, stretching more than 700 feet.
Floating turbines are the only viable option for U.S. states to capture large-scale offshore wind energy in waters too deep for traditional turbines.

As waves grew and gusts increased, a wind turbine bobbed gently, its blades spinning with a gentle woosh. The tempest reached a crescendo with little drama other than splashing water.

The uneventful outcome is exactly what engineers aimed for.

The demonstration featuring a 13-foot-tall floating wind turbine in an indoor pool aimed to ensure it can withstand the strain of powerful water and wind when much larger versions are deployed in the ocean.

It’s the University of Maine’s contribution to a worldwide race to improve floating machines to tap wind that blows across deeper waters offshore, too deep to attach turbines to the seabed with permanent pilings.

In the next decade, UMaine researchers said, they envision turbine platforms floating in the ocean beyond the horizon, stretching more than 700 feet skyward and anchored with mooring lines.

“These structures are massive,” said Anthony Viselli, chief engineer for offshore wind technology at the university’s Advanced Composites Center, after the demonstration wrapped up. “These would be some of the largest moving structures that humankind has endeavored to create. And there would be many of them.”

THREE GROUPS ARE SUING NEW JERSEY TO BLOCK AN OFFSHORE WIND FARM

As the technology advances, dozens of designs are being promoted by experts who see floating wind turbines as a way to address climate change by shifting away from burning fossil fuels.

Floating turbines are the only way some countries and U.S. states can capture offshore wind energy on a large scale. In the U.S. alone, 2.8 terawatts of wind energy potential blows over ocean waters too deep for traditional turbines that affix to the ocean floor, according to the National Renewable Energy Laboratory. That’s enough to power 350 million homes — more than double the number of existing homes in the U.S.

The first floating wind farm started operating off Scotland’s coast in 2017. In the United States, the Department of Interior two weeks ago proposed the first floating wind energy auctions for the Gulf of Maine, following lease auctions for the West Coast that began in 2022. The nearly 1 million acres up for auction off the New England coast could generate enough clean wind energy to power more than 5 million local homes, the department said.

UMaine is home to the nation’s largest team of engineers dedicated to floating offshore wind. Other big players include Equinor, which has installed a demonstration floating project of the coast of Norway; global company Principle Power, which has installed small-scale projects off Scotland and Portugal; and SBM Offshore, which has a demonstration project off France.

Floating offshore wind is still a nascent industry, however, making it expensive.

The Norwegian company Equinor postponed its Trollvind floating initiative, citing technology availability, rising costs and a strained timetable to deliver on the original concept.

Danish wind energy developer Ørsted decided to focus its efforts on fixed-bottom turbines, foregoing deeper offshore regions including Japan, Norway, Spain, Portugal and the U.S. West Coast. “We care a lot about affordability of renewable power, and floating wind is a lot more expensive than bottom-fixed,” said CEO Mads Nipper.

But others are moving forward.

Gazelle Wind Power is developing a modular platform system to make manufacture and assembly cost-effective and efficient.

“This is a global problem and this is an ideal solution in order to deliver power to shore,” said Gazelle Wind Power CEO Jon Salazar.

UMaine launched its first floating prototype a decade ago and became a surprise global leader after a study showed that the Gulf of Maine had the wind energy potential of 156 nuclear power plants, due to fast, consistent wind.

The state could meet all its home heating needs and power every car — if they were all electric vehicles — by tapping just 3% of that water. That improves the odds of successfully sharing the resource with fishermen, recreational boaters, the military and, of course, marine life. Indeed, the federal government’s lease proposal spares Maine’s key lobstering grounds from development, removing a potential obstacle.

Trailblazers in offshore wind are benefiting from work done by the oil industry, which engineered floating oil and gas rigs, said Habib Dagher, director of the Advanced Composites Center.

The university’s wind wave basin, which looks something like a swimming pool with wave and wind generators that can mimic ocean conditions up to a 500-year storm, takes that work to the next level.

On a recent day, the semi-submersible floating turbine was tethered to the bottom of the basin. Its 1:70 scale represented a real turbine standing about 800 feet (240 meters) tall atop a platform in the ocean. The goal is to have industrial scale turbines of 15 to 20 megawatts each, Dagher said.

Size and efficiency are keys to profitability. Larger wind turbines mean fewer are needed, reducing construction, installation and maintenance costs, Viselli said. With greater size and efficiency, developers envision only about 50 turbines needed to produce about the same amount of electricity as a nuclear power plant.

Full-size turbines generate peak power starting at about 20 mph. In powerful storms, they shut down automatically to avoid stressing the equipment or breaking. The mooring lines tethered to the ocean floor are made of rope nearly thick as a telephone pole and under heavy tension. That makes them safer for marine mammals.

For all the turbine technology, the platforms developed by UMaine can be built locally with concrete, a simple material that’s readily available. The university already has partners around the world interested in licensing its technology. The state of Maine plans to develop a port facility in the Searsport area to build the floating bases and attach turbines before sending them into the Gulf of Maine.

A brand new industry means some experiments in design will succeed and some will fail. And there is work to ensure that wind farms are good neighbors, overcoming objections from others using the ocean.

“We’re going to have some problems and we have to figure out how to roll up our sleeves and solve these problems,” Dagher said. “And I think we have no choice as a society but to do that.”

There is no fix for Intel’s crashing 13th and 14th Gen CPUs — any damage is permanent

There is no fix for Intel’s crashing 13th and 14th Gen CPUs — any damage is permanent

On Monday, it initially seemed like the beginning of the end for Intel’s desktop CPU instability woes — the company confirmed a patch is coming in mid-August that should address the “root cause” of exposure to elevated voltage. But if your 13th or 14th Gen Intel Core processor is already crashing, that patch apparently won’t fix it.

Citing unnamed sources, Tom’s Hardware reports that any degradation of the processor is irreversible, and an Intel spokesperson did not deny that when we asked. Intel is “confident” the patch will keep it from happening in the first place. (As another preventative measure, you should update your BIOS ASAP.) But if your defective CPU has been damaged, your best option is to replace it instead of tweaking BIOS settings to try and alleviate the problems.

And, Intel confirms, too-high voltages aren’t the only reason some of these chips are failing. Intel spokesperson Thomas Hannaford confirms it’s a primary cause, but the company is still investigating. Intel community manager Lex Hoyos also revealed some instability reports can be traced back to an oxidization manufacturing issue that was fixed at an unspecified date last year.

This raises lots of questions. Will Intel recall these chips? Extend their warranty? Replace them no questions asked? Pause sales like AMD just did with its Ryzen 9000? Identify faulty batches with the manufacturing defect?

We asked Intel these questions, and I’m not sure you’re going to like the answers.

Why are these still on sale without so much as an extended warranty?

Intel has not halted sales or clawed back any inventory. It will not do a recall, period. The company is not currently commenting on whether or how it might extend its warranty. It would not share estimates with The Verge of how many chips are likely to be irreversibly impacted, and it did not explain why it’s continuing to sell these chips ahead of any fix.

Intel’s not yet telling us how warranty replacements will work beyond trying customer support again if you’ve previously been rejected. It did not explain how it will contact customers with these chips to warn them about the issue.

But Intel does tell us it’s “confident” that you don’t need to worry about invisible degradation. If you’re not currently experiencing issues, the patch “will be an effective preventative solution for processors already in service.” (If you don’t know if you’re experiencing issues, Intel currently suggests the Robeytech test.)

And, perhaps for the first time, Intel has confirmed just how broad this issue could possibly be. The elevated voltages could potentially affect any 13th or 14th Gen desktop processor that consumes 65W or more power, not just the highest i9-series chips that initially seemed to be experiencing the issue.

Here are the questions we asked Intel and the answers we’ve received by email from Intel’s Hannaford:

How many chips does Intel estimate are likely to be irreversibly impacted by these issues?

Intel Core 13th and 14th Generation desktop processors with 65W or higher base power – including K/KF/KS and 65W non-K variants – could be affected by the elevated voltages issue. However, this does not mean that all processors listed are (or will be) impacted by the elevated voltages issue.

Intel continues validation to ensure that scenarios of instability reported to Intel regarding its Core 13th and 14th Gen desktop processors are addressed.

For customers who are or have been experiencing instability symptoms on their 13th and/or 14th Gen desktop processors, Intel continues advising them to reach out to Intel Customer Support for further assistance. Additionally, if customers have experienced these instability symptoms on their 13th and/or 14th Gen desktop processors but had RMA [return merchandise authorization] requests rejected we ask that they reach out to Intel Customer Support for further assistance and remediation.

Will Intel issue a recall?

Will Intel proactively warn buyers of these chips about the warning signs or that this update is required? If so, how will it warn them?

Intel targets to release a production microcode update to OEM/ODM customers by mid-August or sooner and will share additional details on the microcode patch at that time.

Intel is investigating options to easily identify affected processors on end user systems. In the interim, as a general best practice Intel recommends that users adhere to Intel Default Settings on their desktop processors, along with ensuring their BIOS is up to date.

Has Intel halted sales and / or performed any channel inventory recalls while it validates the update?

Does Intel anticipate the fix will be effective for chips that have already been in service but are not yet experiencing symptoms (i.e., invisible degradation)? Are those CPUs just living on borrowed time?

Intel is confident that the microcode patch will be an effective preventative solution for processors already in service, though validation continues to ensure that scenarios of instability reported to Intel regarding its Core 13th/14th Gen desktop processors are addressed.

Intel is investigating options to easily identify affected or at-risk processors on end user systems.

It is possible the patch will provide some instability improvements to currently impacted processors; however customers experiencing instability on their 13th or 14th Generation desktop processor-based systems should contact Intel customer support for further assistance.

Will Intel extend its warranty on these 13th Gen and 14th Gen parts, and for how long?

Given how difficult this issue was for Intel to pin down, what proof will customers need to share to obtain an RMA? (How lenient will Intel be?)

What will Intel do for 13th Gen buyers after supply of 13th Gen parts runs out? Final shipments were set to end last month, I’m reading.

Intel is committed to making sure all customers who have or are currently experiencing instability symptoms on their 13th and/or 14th Gen desktop processors are supported in the exchange process. This includes working with Intel’s retail and channel customers to ensure end users are taken care of regarding instability symptoms with their Intel Core 13th and/or 14th Gen desktop processors.

What will Intel do for 14th Gen buyers after supply of 14th Gen parts run out?

Will replacement / RMA’d chips ship with the microcode update preapplied beginning in August? Is Intel still shipping replacement chips ahead of that update?

Intel will be applying to microcode to 13th/14th Gen desktop processors that are not yet shipped once the production patch is released to OEM/ODM partners (targeting mid-August or sooner). For 13th /14th Gen desktop processors already in service, users will need to apply the patch via BIOS update once available.

What, if anything, can customers do to slow or stop degradation ahead of the microcode update?

Intel recommends that users adhere to Intel Default Settings on their desktop processors, along with ensuring their BIOS is up to date. Once the microcode patch is released to Intel partners, we advise users check for the relevant BIOS updates.

Will Intel share specific manufacturing dates and serial number ranges for the oxidized processors so mission-critical businesses can selectively rip and replace?

Intel will continue working with its customers on Via Oxidation-related reports and ensure that they are fully supported in the exchange process.

Why does Intel believe the instability issues do not affect mobile laptop chips?

Intel is continuing its investigation to ensure that reported instability scenarios on Intel Core 13th/14th Gen processors are properly addressed.

This includes ongoing analysis to confirm the primary factors preventing 13th / 14th Gen mobile processor exposure to the same instability issue as the 13th/14th Gen desktop processors.

That’s all we’ve heard from Intel so far, though Hannaford assured us more answers are on the way and that the company is working on remedies.

Again, if your CPU is already damaged, you need to get Intel to replace it, and if Intel won’t do so, please let us know. In the meanwhile, you’ll want to update your BIOS as soon as possible because your processor could potentially be invisibly damaging itself — and if you know your way around a BIOS, you may want to adjust your motherboard to Intel’s default performance profiles, too.

Lastly, here is that Robeytech video that Intel is recommending to Redditors to potentially help them identify if their chip has an issue. Intel says it’s looking into other ways to identify that, too.
