Australia Criticized For Ramping Up Gas Extraction Through '2050 and Beyond' (bbc.com) 132

Slashdot reader sonlas shared this report from the BBC: Australia has announced it will ramp up its extraction and use of gas until "2050 and beyond", despite global calls to phase out fossil fuels. Prime Minister Anthony Albanese's government says the move is needed to shore up domestic energy supply while supporting a transition to net zero... Australia — one of the world's largest exporters of liquefied natural gas — has also said the policy is based on "its commitment to being a reliable trading partner". Released on Thursday, the strategy outlines the government's plans to work with industry and state leaders to increase both the production and exploration of the fossil fuel. The government will also continue to support the expansion of the country's existing gas projects, the largest of which are run by Chevron and Woodside Energy Group in Western Australia...

The policy has sparked fierce backlash from environmental groups and critics — who say it puts the interest of powerful fossil fuel companies before people. "Fossil gas is not a transition fuel. It's one of the main contributors to global warming and has been the largest source of increases of CO2 [emissions] over the last decade," Prof Bill Hare, chief executive of Climate Analytics and author of numerous UN climate change reports told the BBC... Successive Australian governments have touted gas as a key "bridging fuel", arguing that turning it off too soon could have "significant adverse impacts" on Australia's economy and energy needs. But Prof Hare and other scientists have warned that building a net zero policy around gas will "contribute to locking in 2.7-3C global warming, which will have catastrophic consequences".

Are Small Modular Nuclear Reactors Costly and Unviable? (cosmosmagazine.com) 215

The Royal Institution of Australia is a national non-profit hub for science communication, publishing the science magazine Cosmos four times a year.

This month they argued that small modular nuclear reactors "don't add up as a viable energy source." Proponents assert that SMRs would cost less to build and thus be more affordable. However, when evaluated on the basis of cost per unit of power capacity, SMRs will actually be more expensive than large reactors. This 'diseconomy of scale' was demonstrated by the now-terminated proposal to build six NuScale Power SMRs (77 megawatts each) in Idaho in the United States. The final cost estimate of the project per megawatt was around 250 percent more than the initial per megawatt cost for the 2,200 megawatts Vogtle nuclear power plant being built in Georgia, US. Previous small reactors built in various parts of America also shut down because they were uneconomical.
The cost was four to six times the cost of the same electricity from wind and solar photovoltaic plants, according to estimates from the Australian Commonwealth Scientific and Industrial Research Organisation and the Australian Energy Market Operator. "The money invested in nuclear energy would save far more carbon dioxide if it were instead invested in renewables," the article agues: Small reactors also raise all of the usual concerns associated with nuclear power, including the risk of severe accidents, the linkage to nuclear weapons proliferation, and the production of radioactive waste that has no demonstrated solution because of technical and social challenges. One 2022 study calculated that various radioactive waste streams from SMRs would be larger than the corresponding waste streams from existing light water reactors...

Nuclear energy itself has been declining in importance as a source of power: the fraction of the world's electricity supplied by nuclear reactors has declined from a maximum of 17.5 percent in 1996 down to 9.2 percent in 2022. All indications suggest that the trend will continue if not accelerate. The decline in the global share of nuclear power is driven by poor economics: generating power with nuclear reactors is costly compared to other low-carbon, renewable sources of energy and the difference between these costs is widening.

Former Boeing Quality Inspector Turns Whistleblower, Says Plane Parts Had Serious Defects (bbc.com) 131

Thursday the BBC reported: Plane bodies made by Boeing's largest supplier regularly left the factory with serious defects, according to a former quality inspector at the firm. Santiago Paredes who worked for Spirit AeroSystems in Kansas, told the BBC he often found up to 200 defects on parts being readied for shipping to Boeing. He was nicknamed "showstopper" for slowing down production when he tried to tackle his concerns, he claimed.

Spirit said it "strongly disagree[d]" with the allegations. "We are vigorously defending against his claims," said a spokesperson for Spirit, which remains Boeing's largest supplier.

Mr Paredes made the allegations against Spirit in an exclusive interview with the BBC and the American network CBS, in which he described what he said he experienced while working at the firm between 2010 and 2022... "I was finding a lot of missing fasteners, a lot of bent parts, sometimes even missing parts...." Mr Paredes told the BBC that some of the defects he identified while at Spirit were minor — but others were more serious. He also claimed he was put under pressure to be less rigorous...

He now maintains he would be reluctant to fly on a 737 Max, in case it still carried flaws that originated in the Wichita factory. "I'd never met a lot of people who were scared of flying until I worked at Spirit," he said. "And then, being at Spirit, I met a lot of people who were afraid of flying — because they saw how they were building the fuselages."

"If quality mattered, I would still be at Spirit," Paredes told CBS News, speaking publicly for the first time. CBS News spoke with several current and former Spirit AeroSystems employees and reviewed photos of dented fuselages, missing fasteners and even a wrench they say was left behind in a supposedly ready-to-deliver component. Paredes said Boeing knew for years Spirit was delivering defective fuselages.
It could be just a coincidence, but the same day, the Associated Press ran story with this headline.

"Boeing plane carrying 85 people catches fire and skids off the runway in Senegal, injuring 10." It was the third incident involving a Boeing airplane this week. Also on Thursday, 190 people were safely evacuated from a plane in Turkey after one of its tires burst during landing at a southern airport, Turkey's transportation ministry said.

Could Stem Cells One Day Cure Diabetes? (medscape.com) 42

Brian Shelton's type 1 diabetes was treated with an infusion of insulin-producing pancreas cells (grown from stem cells). In 2021, the New York Times reported: Now his body automatically controls its insulin and blood sugar levels. Shelton, now 64, may be the first person cured of the disease with a new treatment that has experts daring to hope that help may be coming for many of the 1.5 million Americans suffering from Type 1 diabetes. "It's a whole new life," Shelton said. Diabetes experts were astonished but urged caution. The study is continuing and will take five years, involving 17 people with Type 1 diabetes.
"By fall 2023, three patients, including Shelton, had achieved insulin independence by day 180 post-transplant," MedScape reported (in January of 2024): In the phase 1/2 study, 14 patients with type 1 diabetes and impaired hypoglycemia awareness or recurrent hypoglycemia received portal vein infusions of VX-880 [Vertex Pharmaceutical's pancreatic islet cell replacement therapy] along with standard immunosuppression. As of the last data cut, all 14 patients demonstrated islet cell engraftment and production of endogenous insulin. After more than 90 days of follow-up, 13 of the patients have achieved A1c levels < 7% without using exogenous insulin.
Brian Shelton and another patient died, and while Vertex says their deaths were unrelated to the treatment, they have "placed the study on a protocol-specified pause, pending review of the totality of the data by the independent data monitoring committee and global regulators." (MedScape adds that Vertex "is continuing with a phase 1/2 clinical trial of a different product, VX-264, which encapsulates the same VX-880 cells in a device designed to eliminate the need for immunosuppression.")

And meanwhile, a new study in China (again using stem cell-derived islet tissue) has provided "encouraging evidence that islet tissue replacement is an effective cure for diabetic patients," the researchers wrote in Nature. The treatment was administered to 59-year-old, type-2 diabetic.

"Marked changes in the patient's glycemic control were observed as early as week 2," the researchers write, and after week 32, the patient's Time In Tight Range (TITR) "had readily reached 99% and was maintained thereafter."

The Automotive Cold War Is Officially Underway (insideevs.com) 170

Tim Levin reports via InsideEVs: Two things of note in the electric vehicle world happened today around the same time. First, the Geely Group-owned Chinese EV brand Zeekr debuted on the New York Stock Exchange today at a valuation of around $5.2 billion. Then, around 250 miles south in Washington, D.C., news emerged that the Biden Administration is set to quadruple tariffs on Chinese-made electric cars if they hit American roads. The timing may be purely coincidental. But after this week, one thing feels clearer than ever: the automotive Cold War between China and the West is fully underway, and EVs specifically are at the center of it all.

The Wall Street Journal got the scoop that the White House plans to announce higher tariffs on Chinese clean-energy imports in the coming days. Under the reported new policies, tariffs on Chinese EVs are set to quadruple, rising from the current 25% to a whopping 100%, anonymous sources told the outlet. In theory, that would substantially increase the cost of any Chinese-made EVs on our market, including, potentially, ones sold by known Western and other Asian brands. It's no secret why the U.S. is attempting to push back on Chinese EVs, to say nothing of other clean energy imports from that country like solar panels. China has spent years aggressively building up its capacity to manufacture electric cars. It's developed a stranglehold on the supply chains for lithium-ion batteries and the critical minerals they contain. It has lavished state incentives on both EV production and purchasing. In recent years, the country has emerged as a global EV powerhouse -- and, for the first time ever, an exporter on par with leaders like Japan and Germany.

Many still believe that China's cars are cheap and technologically subpar. But the truth is China has learned to build cars very, very well, as InsideEVs' own Kevin Williams discovered during a recent trip to the Beijing auto show. China's homegrown electrified vehicles range from the inexpensive -- some, like the BYD Seagull, cost less than $10,000 in their home market -- to higher-end, luxury-focused offerings like the Yangwang U8, a kind of plug-in hybrid competitor to the Mercedes G-Class that can "float" on water. From batteries to software, most are incredibly advanced. Car companies and policymakers in the U.S. (and Europe) say these cars pose a real threat to our nascent EV market, where many options still remain unaffordable and things like batteries and software are works in progress. In response, European Union officials have also launched investigations into Chinese imports that could lead to stronger tariffs.
"In effect, the tariffs may end up buying the U.S. some time, rather than being a permanent solution here," concludes Levin. "After all, as Kevin Williams pointed out after going to Beijing: all of these crackdowns aren't guaranteed to yield better cars from Ford, General Motors and the rest."

According to the WSJ, the new tariffs on Chinese goods will also apply to solar panels, batteries and critical battery minerals. They're expected to be announced as soon as next week.

UK Economy Emerges From Recession 29

The U.K. economy has emerged from recession as gross domestic product rose 0.6% in the first quarter, official figures showed Friday, beating expectations. From a report: Economists polled by Reuters had forecast growth of 0.4% on the previous three months of the year. The U.K. entered a shallow recession in the second half of 2023, as persistent inflation continued to hurt the economy.

Although there is no official definition of a recession, two straight quarters of negative growth is widely considered a technical recession. The U.K.'s production sector expanded by 0.8% in the period from January to March, while construction fell by 0.9%. On a monthly basis, the economy grew by 0.4% in March, following 0.2% expansion in February. In output terms, the services sector -- crucial to the U.K. economy -- grew for the first time since the first quarter in 2023, the Office for National Statistics said. The 0.7% growth was mainly driven by the transport services industry which saw its highest quarterly growth rate since 2020.

Boeing Says Workers Skipped Required Tests on 787 But Recorded Work as Completed (arstechnica.com) 127

An anonymous reader shares a report: The Federal Aviation Administration is investigating whether Boeing failed to complete required inspections on 787 Dreamliner planes and whether Boeing employees falsified aircraft records, the agency said this week. The investigation was launched after an employee reported the problem to Boeing management, and Boeing informed the FAA. "The FAA has opened an investigation into Boeing after the company voluntarily informed us in April that it may not have completed required inspections to confirm adequate bonding and grounding where the wings join the fuselage on certain 787 Dreamliner airplanes," the FAA said in a statement provided to Ars today. The FAA said it "is investigating whether Boeing completed the inspections and whether company employees may have falsified aircraft records. At the same time, Boeing is reinspecting all 787 airplanes still within the production system and must also create a plan to address the in-service fleet." The agency added that it "will take any necessary action -- as always -- to ensure the safety of the flying public."

Boeing VP Scott Stocker, who leads the 787 Dreamliner program, described "misconduct" in an April 29 email to employees in South Carolina. Boeing provided a copy of the email to Ars. "After receiving the report, we quickly reviewed the matter and learned that several people had been violating Company policies by not performing a required test, but recording the work as having been completed," Stocker wrote. "As you all know, we have zero tolerance for not following processes designed to ensure quality and safety. We promptly informed our regulator about what we learned and are taking swift and serious corrective action with multiple teammates."

Ten Years Ago Microsoft Bought Nokia's Phone Unit, Then Killed It As a Tax Write-Off (theregister.com) 82

The Register provides a retrospective look at how Microsoft "absorbed the handset division of Nokia" ten years ago, only to kill the unit two years later and write it off as a tax loss. What went wrong? "It was a fatal combination of bad management, a market evolving in ways hidebound people didn't predict, and some really (with a few superb exceptions) terrible products," reports The Register. From the report: Like Nokia, Windows Mobile's popularity peaked in 2007, then started to drop away. The iPhone was the tech item of choice for fashionistas, Blackberry was seen as essential for serious business, and Android -- with Google as its new owner -- was gaining traction. Microsoft by that time had a new CEO in Steve Ballmer, who completely and famously failed to see the shifting sands in the mobile market. He dismissed the iPhone as a threat to what he thought was Windows Mobile's unassailable market position, and was roundly mocked for it. So the scene was set for a mobile standards war, and Steve Ballmer staked his professional pride on winning it. Microsoft recruited Nokia to help out. [...]

Under [Executive VP of Microsoft Stephen Elop's] leadership, a closer working relationship with Microsoft was a given -- but in 2013 Redmond announced it was going the whole hog and buying Nokia's handset business outright for $7.2 billion. The deal was done in April 2014, a decade ago from today. Microsoft also got a ten-year license on Nokia's patents and the option to renew in perpetuity. It also got Elop back, as executive vice president of the Microsoft Devices Group. That meant stepping down as CEO of Nokia, for which he trousered an 18.8 million bonus package -- a payoff the Finnish prime minister at the time called "outrageous." Nokia retained its networking business in Finland. It purchased Siemens' half of the Nokia Siemens Networks joint venture and renamed in Nokia Networks. The Nokia board rolled the dice again on hiring another non-Suomi manager, Rajeev Suri, and this time hit a double D20 in D&D terms.

When Ballmer stepped down from the helm at Microsoft in 2014 -- shortly before the Nokia deal completion -- he left a hot mess to deal with. His plan had been to develop the mobile operating system in conjunction with Windows 10, and Windows Mobile 10 was supposed to be a part of a unified code environment. While Windows 10 on the desktop wasn't a bad operating system, Windows Mobile 10 really was. The promised synergy just didn't happen -- it was power-hungry, clunky, and about as popular as a rattlesnake in a pinata. It was this mess that Satya Nadella faced when he took over the reins. Nadella was never very keen on the phone platform and spent more time in press conferences talking about cricket or the cloud than Microsoft's mobile ambitions. It was clear to all that this really wasn't working. Elop was laid off by Redmond a year later.

It was clear that Windows Mobile wasn't going to work. Android and iOS were drinking Microsoft's milkshake, and Redmond realized the game was up. Microsoft started shedding mobile jobs -- both in Finland and Redmond. While mobile was still publicly touted as the way forward for Microsoft with Ballmer gone, the impetus wasn't there and support for the mobile OS shriveled. In 2015 Microsoft declared it was writing off $7.6 billion on the Phone Hardware division as "goodwill and asset impairment charges" -- $400 million more than it had originally paid for the Finnish firm. Nokia bought European networking giant Alcatel-Lucent in a $16.7 billion deal in 2015. Around the same time, Suri announced a move into tablets, since it had a non-compete agreement with Microsoft on mobiles. Meanwhile a bunch of former Nokia execs who'd fled Elop and Microsoft had started a mobile biz of their own: HMD. It was Finnish, but outsourced production to Foxconn in China, and was planning to make cheapish Android devices. In 2016 Microsoft sold its mobile hardware arm to HMD for an undisclosed -- but probably not large -- sum. Nadella clearly wanted out of the whole business and the Finnish startup concentrated on selling good-enough Android smartphones to Nokia's traditional cheap markets.

Star Wars Prequels

How 'Star Wars' was Influenced by San Francisco - and Architecture (sfgate.com) 49

"Without San Francisco, Star Wars wouldn't exist," says David Reat, the culture studies director of the architecture department at Glasgow's University of Strathclyde.

SFGate reports: Lucas was born and raised in Modesto, where his father expected him to run the family stationery store once he turned 18, but Lucas instead left for Los Angeles, where he studied film production at the University of Southern California, before moving to San Francisco. Despite all that these cities had to offer, Lucas constantly found himself conflicted over his feelings toward them. "The battle of living in the country versus living in the city is huge with Lucas," says Reat, who notes that this theme runs throughout the likes of "THX 1138," "American Graffiti" and the "Star Wars" series. "He sees cities as the givers and takers of things. He's fascinated by cities. He doesn't actually want to live in one. He now lives in a ranch near one. He wants to orbit them. He's a paradox."

When Lucas moved to San Francisco in the late 1960s, there were a number of huge building projects taking place across the city that piqued the burgeoning filmmaker's interest, most notably the construction of BART and a new terminal at San Francisco airport. "Infrastructure really fascinated Lucas. They were these big huge alienating spaces," says Reat. "I think Lucas was driving around San Francisco, looking at them, and seeing that they looked alien." There's a reason why Lucas was particularly interested in the architecture in San Francisco: "He's on record as saying he wanted to be an architect," says Reat. "He has referred to himself as a frustrated architect." Lucas' interest provoked him and his creative team to put extra care and thought into each of the "Star Wars" buildings, vehicles, houses, villages, cities, worlds and galaxies, especially when it came to what they symbolized and represented.

"The architecture in the films play a key role for younger viewers," says Reat, explaining that it helps to indicate who is good and who is evil. When it comes to the Death Star there are "no women, no plants, no signs of life, and it's basically the Nazis in space," continues Reat. "Lucas doesn't like modernism. He always uses it for bad things, a bit like every James Bond baddie." Meanwhile, Luke Skywalker and the rest of the light side of the Force are seen living in "exaggerated domesticity" as they sit around drinking blue milk, surrounded by creatures. "There's a care and a weirdness to their architecture, plus it's loaded with color," says Reat, who adds that these choices help to make those characters more appealing and relatable....

The San Francisco International Airport also played a key role in the making of "Phantom Menace." A tour of its maintenance bay gave the film's creative designers a jolt of inspiration when they were creating Anakin's podracer and other vehicles.

The article also adds that the inspiration for the Theed Royal Palace on Naboo in The Phantom Menace was "the Marin County Civic Center, where Lucas once served jury duty."

Scientists Find a 'Missing Link' Between Poor Diet and Higher Cancer Risk (sciencealert.com) 57

Science Alert reports that a team of researchers found "that changes in glucose metabolism could help cancer grow by temporarily disabling a gene that protects us from tumors called BRCA2." The team first examined people who inherited one faulty copy of BRCA2. They found that cells from these people were more sensitive to methylglyoxal (MGO), which is produced when cells break down glucose for energy in the process of glycolysis. Glycolysis generates over 90 percent of the MGO in cells, which a pair of enzymes typically keep to minimal levels. In the event they can't keep up, high MGO levels can lead to the formation of harmful compounds that damage DNA and proteins. In conditions like diabetes, where MGO levels are elevated due to high blood sugar, these harmful compounds contribute to disease complications.

The researchers discovered that MGO can temporarily disable the tumor-suppressing functions of the BRCA2 protein, resulting in mutations linked to cancer development...

As the BRCA2 allele isn't permanently inactivated, functional forms of the protein it produces can later return to normal levels. But cells repeatedly exposed to MGO may continue to accumulate cancer-causing mutations whenever existing BRCA2 protein production fails. Overall, this suggests that changes in glucose metabolism can disrupt BRCA2 function via MGO, contributing to the development and progression of cancer...

This new information may lead to strategies for cancer prevention or early detection. "Methylglyoxal can be easily detected by a blood test for HbA1C, which could potentially be used as a marker," Venkitaraman says. "Furthermore, high methylglyoxal levels can usually be controlled with medicines and a good diet, creating avenues for proactive measures against the initiation of cancer."

Their research has been published in Cell.

Lithium-Free Sodium Batteries Exit the Lab, Enter US Production (newatlas.com) 138

Natron Energy, a pioneer in sodium-ion battery technology, has officially commenced mass production of its lithium-free sodium batteries in its Holland, Michigan facility, offering an alternative energy storage solution with benefits such as faster cycling, longer lifespan, and safer usage compared to lithium-ion batteries. New Atlas reports: Not only is sodium somewhere between 500 to 1,000 times more abundant than lithium on the planet we call Earth, sourcing it doesn't necessitate the same type of earth-scarring extraction. Even moving beyond the sodium vs lithium surname comparison, Natron says its sodium-ion batteries are made entirely from abundantly available commodity materials that also include aluminum, iron and manganese. Furthermore, the materials for Natron's sodium-ion chemistry can be procured through a reliable US-based domestic supply chain free from geopolitical disruption. The same cannot be said for common lithium-ion materials like cobalt and nickel.

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage. [...] Natron says its batteries charge and discharge at rates 10 times faster than lithium-ion, a level of immediate charge/discharge capability that makes the batteries a prime contender for the ups and downs of backup power storage. Also helping in that use case is an estimated lifespan of 50,000 cycles.

Whistleblower Josh Dean of Boeing Supplier Spirit AeroSystems Has Died (seattletimes.com) 174

Joshua Dean, a former quality auditor at Boeing supplier Spirit AeroSystems and one of the first whistleblowers to allege Spirit leadership had ignored manufacturing defects on the 737 MAX, died Tuesday morning after a struggle with a sudden, fast-spreading infection. Seattle Times: Known as Josh, Dean lived in Wichita, Kan., where Spirit is based. He was 45, had been in good health and was noted for having a healthy lifestyle. He died after two weeks in critical condition, his aunt Carol Parsons said. Dean had given a deposition in a Spirit shareholder lawsuit and also filed a complaint with the Federal Aviation Administration alleging "serious and gross misconduct by senior quality management of the 737 production line" at Spirit.

Spirit fired Dean in April 2023, and he had filed a complaint with the Department of Labor alleging his termination was in retaliation for raising concerns related to aviation safety. Parsons said Dean became ill and went to the hospital because he was having trouble breathing just over two weeks ago. He was intubated and developed pneumonia and then a serious bacterial infection, MRSA. His condition deteriorated rapidly, and he was airlifted from Wichita to a hospital in Oklahoma City, Parsons said. There he was put on an ECMO machine, which circulates and oxygenates a patient's blood outside the body, taking over heart and lung function when a patient's organs don't work on their own.

PFAS Increase Likelihood of Death By Cardiovascular Disease, Study Shows (theguardian.com) 34

New submitter berghem shares a report from The Guardian: For the first time, researchers have formally shown that exposure to toxic PFAS increases the likelihood of death by cardiovascular disease, adding a new level of concern to the controversial chemicals' wide use. The findings are especially significant because proving an association with death by chemical exposure is difficult, but researchers were able to establish it by reviewing death records from northern Italy's Veneto region, where many residents for decades drank water highly contaminated with PFAS, also called "forever chemicals." Records further showed an increased likelihood of death from several cancers, but stopped short of establishing a formal association because of other factors. [...]

Veneto's drinking water was widely contaminated by a PFAS-production plant between 1985 and 2018. Researchers first found an excess of about 4,000 deaths during this period, or about one every three days. Part of the region was supplied with water from a different source, giving researchers the opportunity to compare records for tens of thousands of people who drank contaminated water and lived near those who did not. Though PFAS can affect the cardiovascular system in different ways, it is largely a problem because it produces stubbornly high and dangerous levels of cholesterol. The levels are difficult to control because they aren't caused by dietary or lifestyle choices that can be addressed with adjustments, but hormonal changes that affect the metabolism and the body's ability to control plaque in arteries. The study's authors suspect that post-traumatic stress disorder caused by the environmental disaster, which upended lives across the region, may also be contributing to circulatory disease. The evidence of a jump in kidney cancer was also "very clear," [said Annibale Biggeri, the peer-reviewed study's lead author, and a researcher with the University of Padua]. In the study's first five years, 16 cases were recorded, while 65 were recorded in the last five years. It also found elevated levels of testicular cancer during some time periods.

The records "showed clearly" that earlier life exposures led to higher levels of mortality, except for women who have multiple children. Previous research has found levels were higher in women with only one child. The chemicals accumulate in placentas and are passed on to children during pregnancy, which reduces levels in the body. Mortality levels among women who were of child-bearing age were generally lower, but increased in older women. The chemicals will be passed down to children for generations, said Laura Facciolo, a Veneto resident who drank contaminated water. She said the findings underscore the need to ban PFAS, and the disaster's injustice.
The findings have been published in the journal Environmental Health.

America's Wind Power Production Drops For the First Time In 25 Years (yahoo.com) 110

An anonymous reader quotes a report from Bloomberg: U.S. wind power slipped last year for the first time in a quarter-century due to weaker-than-normal Midwest breezes, underscoring the challenge of integrating volatile renewable energy sources into the grid. Power produced by turbines slipped 2% in 2023, even after developers added 6.2 gigawatts of new capacity, according to a government report Tuesday. The capacity factor for the country's wind fleet -- how much energy it's actually generating versus its maximum possible output -- declined to an eight-year low of 33.5%. Most of that decline was driven by the central US, a region densely dotted with turbines.

Wind is a key component of the effort to cut carbon emissions, but the data highlights the downside of relying on intermittent energy sources tied to the effects of global weather. Last year's low wind speeds came during El Nino, a warming of the equatorial Pacific that tends to weaken trade winds. La Nina, the Pacific cooling pattern that dominated in 2022 and is poised to return later this year, usually has the opposite effect.
The U.S. Energy Information Administration shared the findings in a report published earlier today.

G7 Reaches Deal To Exit From Coal By 2035 148

An anonymous reader quotes a report from Reuters: Energy ministers from the Group of Seven (G7) major democracies reached a deal to shut down their coal-fired power plants in the first half of the 2030s, in a significant step towards the transition away from fossil fuels. "There is a technical agreement, we will seal the final political deal on Tuesday," said Italian energy minister Gilberto Pichetto Fratin, who is chairing the G7 ministerial meeting in Turin. On Tuesday the ministers will issue a final communique detailing the G7 commitments to decarbonize their economies. Pichetto said the ministers were also pondering potential restrictions to Russian imports of liquefied natural gas to Europe which the European Commission is due to propose in the short-term.

The agreement on coal marks a significant step in the direction indicated last year by the COP28 United Nations climate summit to phase out fossil fuels, of which coal is the most polluting. Italy last year produced 4.7% of its total electricity through a handful of coal-fired stations. Rome currently plans to turn off its plants by 2025, except on the island of Sardinia where the deadline is 2028. In Germany and Japan coal has a bigger role, with the share of electricity produced by the fuel higher than 25% of total last year.
"This is another nail in the coffin for coal," said Dave Jones, Ember's Global Insights program director. "The journey to phase out coal power has been long: it's been over seven years since the UK, France, Italy, and Canada committed to phase out coal power, so it's good to see the United States and especially Japan at last be more explicit on their intentions."

"The problem is that whilst coal power has already been falling, gas power has not. G7 nations already promised to 'fully or predominantly' decarbonize their power sectors by 2035, and that would mean phasing out not only coal by 2035 but also gas. Coal might be the dirtiest, but all fossil fuels need to be ultimately phased out."

Countries Consider Pact To Reduce Plastic Production By 40% in 15 Years (theguardian.com) 43

Countries are for the first time considering restrictions on the global production of plastic -- to reduce it by 40% in 15 years -- in an attempt to protect human health and the environment. From a report: As the world attempts to make a treaty to cut plastic waste at UN talks in Ottawa, Canada, two countries have put forward the first concrete proposal to limit production to reduce its harmful effects including the huge carbon emissions from producing it. The motion submitted by Rwanda and Peru sets out a global reduction target, ambitiously termed a "north star," to cut the production of primary plastic polymers across the world by 40% by 2040, from a 2025 baseline.

It says: "The effectiveness of both supply and demand-side measures will be assessed, in whole or in part, on their success in reducing the production of primary plastic polymers to sustainable levels." The proposal calls for the consideration of mandatory reporting by countries of statistical data on production, imports and exports of primary plastic polymers. A global plastic reduction target would be similar to the legally binding Paris agreement to pursue efforts to limit global temperature increase to 1.5C above preindustrial levels, Rwanda and Peru said.

Behold the World's Largest 3D Printer (apnews.com) 31

They're calling it "the world's largest 3D printer," but also "the factory of the future" — not just a 3D printer, but a manufacturing system. It's the succcessor to a 3D printer that could create an entire house, cutting construction time and labor, according to the Associated Press. And this one "may one day create entire neighborhoods." It has a voracious appetite, consuming as much as 500 pounds (227 kilograms) of material per hour... The university wants to show how homes can be constructed nearly entirely by a printer with a lower carbon footprint. The buildings and construction sector accounts for roughly 37% of global greenhouse gas emissions, largely due to the production and use of materials such as cement, steel and aluminum that have a significant carbon footprint, according to the United Nations Environment Programme. Such printed buildings can be recycled, which is unique compared to current construction. "You can basically deconstruct it, you can grind it up if you wish, the 3D printed parts, and reprint with them, do it again," Dagher said before the event...

But it can be used for a variety of other creations and already has been used for a range of things, from boats to defense department structures.

The project is partly funded by the U.S. military, according to the BBC. "Maine University says it hopes the printer can be used to make affordable housing, as well as bridges, boats and wind turbines."

Boeing Accused of Retaliating Against Two Engineers in 2022 (reuters.com) 51

Reuters reports that America's Federal Aviation Administration "is investigating a union's claims that Boeing retaliated against two employees who in 2022 insisted the planemaker re-evaluate prior engineering work on 777 and 787 jets."

The employees' union "said the two unidentified engineers were representatives of the FAA, which delegates some of its oversight authority and certification process to Boeing workers." The FAA noted on Tuesday that in 2022 it boosted oversight of planemakers by protecting aviation industry employees who perform agency functions from interference by their employers. A December 2021 Senate report found "FAA's certification process suffers from undue pressure on line engineers and production staff."

"Boeing can tell Congress and the media all it wants about how retaliation is strictly prohibited," said SPEEA Director of Strategic Development Rich Plunkett. "But our union is fighting retaliation cases on a regular basis, and, in this specific case, Boeing is trying to hide information that would shed light on what happened...."

Last week, Boeing quality engineer whistleblower Sam Salehpour, who raised questions about Boeing widebody jets, told senators he was told to "shut up" when he flagged safety concerns. He has said he was removed from the 787 program and transferred to the 777 jet due to his questions.

Boeing has "zero tolerance for retaliation," according a statement quoted by Reuters, in which the company says they "encourage our employees to speak up when they see an issue. After an extensive review of documentation and interviewing more than a dozen witnesses, our investigators found no evidence of retaliation or interference. We have determined the allegations are unsubstantiated."

The union's version of the story? "After nearly six months of debate, the two engineers, with backing from the FAA, prevailed. Boeing re-did the required analysis." The two engineers were still Boeing employees, however, and Boeing management was not pleased. When they came up for their next performance reviews, the two engineers received identical negative evaluations... Even after the manager of the two engineers admitted that he had rated them both poorly at the request of the 777 and 787 managers who had been forced to resubmit their work, Boeing refused to change the engineers' performance evaluations.

At this point, one of the engineers left in disgust; the other filed a formal "Speak Up" complaint with Boeing.

TSMC Unveils 1.6nm Process Technology With Backside Power Delivery (tomshardware.com) 44

An anonymous reader quotes a report from Tom's Hardware: TSMC announced its leading-edge 1.6nm-class process technology today, a new A16 manufacturing process that will be the company's first Angstrom-class production node and promises to outperform its predecessor, N2P, by a significant margin. The technology's most important innovation will be its backside power delivery network (BSPDN). Just like TSMC's 2nm-class nodes (N2, N2P, and N2X), the company's 1.6nm-class fabrication process will rely on gate-all-around (GAA) nanosheet transistors, but unlike the current and next-generation nodes, this one uses backside power delivery dubbed Super Power Rail. Transistor and BSPDN innovations enable tangible performance and efficiency improvements compared to TSMC's N2P: the new node promises an up to 10% higher clock rate at the same voltage and a 15%-20% lower power consumption at the same frequency and complexity. In addition, the new technology could enable 7%-10% higher transistor density, depending on the actual design.

The most important innovation of TSMC's A16 process, which was unveiled at the company's North American Technology Symposium 2024, is the introduction of the Super Power Rail (SPR), a sophisticated backside power delivery network (BSPDN). This technology is tailored specifically for AI and HPC processors that tend to have both complex signal wiring and dense power delivery networks. Backside power delivery will be implemented into many upcoming process technologies as it allows for an increase in transistor density and improved power delivery, which affects performance. Meanwhile, there are several ways to implement a BSPDN. TSMC's Super Power Rail plugs the backside power delivery network to each transistor's source and drain using a special contact that also reduces resistance to get the maximum performance and power efficiency possible. From a production perspective, this is one of the most complex BSPDN implementations and is more complex than Intel's Power Via.
Volume production of A16 is slated for the second half of 2026. "Therefore, actual A16-made products will likely debut in 2027," notes the report. "This timeline positions A16 to potentially compete with Intel's 14A node, which will be Intel's most advanced node at the time."

Seagate Joins the HDD Price Hike Party, Blames AI for Spike in Demand (theregister.com) 37

Seagate has joined Western Digital in increasing the prices of hard drives, with rising demand due to the huge data requirements of AI taking the blame. AI is also behind a rapid growth in orders for Enterprise solid state drives. From a report: One of the big three makers of traditional rotating hard disk drives, Seagate informed customers that it is increasing prices effective immediately for new orders, but also for any changes to orders that are "over and above" previously committed volumes. This was disclosed in a letter from the company seen by analyst Trendforce, and comes just a couple of weeks after rival manufacturer Western Digital sent out a similar letter to customers informing them of price hikes.

According to Trendforce, the cause of the issue is two-fold: rising demand for high-capacity HDD products driven by the current craze for all things AI, and reduced production by hard drive manufacturers that means they are unable to meet the demand, leading to soaring prices. The rising demand comes from AI training requiring huge volumes of data: OpenAI's GPT-3 model is said to have been trained using 45TB of data, which may have been surpassed for newer models. And while flash-based SSDs boast high-speed and low-latency, storing everything in flash would still be costly. Seagate launched a 30TB hard drive line last year. Hard drive production was cut by as much as 20 percent over the last two years or so because of falling orders during the pandemic, and now manufacturers are unprepared for a sudden uptick in demand.
