What Happens After Throughput to DNA Storage Drives Surpasses 2 Gbps? (ieee.org) 35

High-capacity DNA data storage "is closer than you think," Slashdot wrote in 2019.

Now IEEE Spectrum brings an update on where we're at — and where we're headed — by a participant in the DNA storage collaboration between Microsoft and the Molecular Information Systems Lab of the Paul G. Allen School of Computer Science and Engineering at the University of Washington. "Organizations around the world are already taking the first steps toward building a DNA drive that can both write and read DNA data," while "funding agencies in the United States, Europe, and Asia are investing in the technology stack required to field commercially relevant devices." The challenging part is learning how to get the information into, and back out of, the molecule in an economically viable way... For a DNA drive to compete with today's archival tape drives, it must be able to write about 2 gigabits per second, which at demonstrated DNA data storage densities is about 2 billion bases per second. To put that in context, I estimate that the total global market for synthetic DNA today is no more than about 10 terabases per year, which is the equivalent of about 300,000 bases per second over a year. The entire DNA synthesis industry would need to grow by approximately 4 orders of magnitude just to compete with a single tape drive. Keeping up with the total global demand for storage would require another 8 orders of magnitude of improvement by 2030. But humans have done this kind of scaling up before. Exponential growth in silicon-based technology is how we wound up producing so much data. Similar exponential growth will be fundamental in the transition to DNA storage...

Companies like DNA Script and Molecular Assemblies are commercializing automated systems that use enzymes to synthesize DNA. These techniques are replacing traditional chemical DNA synthesis for some applications in the biotechnology industry... [I]t won't be long before we can combine the two technologies into one functional device: a semiconductor chip that converts digital signals into chemical states (for example, changes in pH), and an enzymatic system that responds to those chemical states by adding specific, individual bases to build a strand of synthetic DNA. The University of Washington and Microsoft team, collaborating with the enzymatic synthesis company Ansa Biotechnologies, recently took the first step toward this device... The path is relatively clear; building a commercially relevant DNA drive is simply a matter of time and money...

At the same time, advances in DNA synthesis for DNA storage will increase access to DNA for other uses, notably in the biotechnology industry, and will thereby expand capabilities to reprogram life. Somewhere down the road, when a DNA drive achieves a throughput of 2 gigabases per second (or 120 gigabases per minute), this box could synthesize the equivalent of about 20 complete human genomes per minute. And when humans combine our improving knowledge of how to construct a genome with access to effectively free synthetic DNA, we will enter a very different world... We'll be able to design microbes to produce chemicals and drugs, as well as plants that can fend off pests or sequester minerals from the environment, such as arsenic, carbon, or gold. At 2 gigabases per second, constructing biological countermeasures against novel pathogens will take a matter of minutes. But so too will constructing the genomes of novel pathogens. Indeed, this flow of information back and forth between the digital and the biological will mean that every security concern from the world of IT will also be introduced into the world of biology...

The future will be built not from DNA as we find it, but from DNA as we will write it.

The article makes an interesting point — that biology labs around the world already order chemically-synthesized ssDNA, "delivered in lengths of up to several hundred bases," and sequence DNA molecules up to thousands of bases in length.

"In other words, we already convert digital information to and from DNA, but generally using only sequences that make sense in terms of biology."

NYC Fails Controversial Remote Learning Snow Day 'Test,' Public Schools Chancellor Says (nbcnews.com) 60

New York City's public schools chancellor said the city did not pass Tuesday's remote learning "test" due to technical issues. From a report: "As I said, this was a test. I don't think that we passed this test," David Banks said during a news briefing, adding that he felt "disappointed, frustrated and angry" as a result of the technical issues. NYC Public Schools did a lot of work to prepare for the remote learning day, Banks said, but shortly before 8 a.m. they were notified that parents and students were having difficulty signing onto remote learning.

This is the first time NYC Public Schools has implemented remote learning on a snow day since introducing the no snow day policy in 2022. The district serves 1.1 million students in more than 1,800 schools. Banks blamed the technical issues on IBM, which helps facilitate the city's remote learning program. "IBM was not ready for primetime," Banks said, adding that the company was overwhelmed with the surge of people signing on for school. IBM has since expanded their capacity and a total of 850,000 students and teachers are currently online, Banks said. "We'll work harder to do better next time," he said, adding that there will be a deeper analysis into what went wrong.

28-Ton, 1.2-Megawatt Tidal Kite Is Now Exporting Power To the Grid (newatlas.com) 65

Minesto, a marine energy tech developer based in Sweden, has deployed their new Dragon 12 tidal energy harvester to the Faroe Islands. Operating like an underwater kite, the Dragon 12 "uses lift generated by tidal flows to fly patterns faster than the currents, harvesting renewable energy," reports New Atlas. From the report: Where devices like Orbital's O2 tidal turbine more or less just sit there in the water harvesting energy from tidal currents, Minesto's Dragon series are anchored to the sea bed, and fly around like kites, treating the currents like wind. Just as land-based wind energy kites fly in figure 8 patterns to accelerate themselves faster than the wind, so does the Dragon underwater. This, says Minesto, lets the Dragon pull more energy from a given tidal current than other designs -- and it also changes the economic equations for relevant sites, making slower tidal flows worth exploiting.

These are by no means small kites -- the Dragon 12 needs to be disassembled to fit in a shipping container. It rocks a monster 12-meter (39-ft) wingspan, and weighs no less than 28 tons. But compared to other offshore power options like wind turbines, it's an absolute minnow, and extremely easy to install using a single smallish boat and a sea bed tether. As with any renewable energy project, the key figure here is LCoE (levelized cost of energy) -- so what's it gonna cost? Well, back in 2017, Minesto projected about US$108/MWh once its first hundred megawatts of capacity are installed -- with costs falling thereafter as low as $54/MWh.

The Dragon 12, like other tidal devices, will be more effective in some places than others -- and Denmark's Faroe Islands, an archipelago in the chilly North Atlantic between Scotland and Iceland, offer ideal conditions. Home to about 55,000 people and more than a million puffins, the Faroe Islands funnel tidal currents through a number of slim channels. This accelerates the water significantly, and thus increases the energy that devices like the Dragon 12 can harvest. That's where the first Dragon has been deployed, and on Friday, it was connected to the local power grid to begin delivering energy.
You can watch a video of the Dragon 12 on YouTube.

Sam Altman Seeks Trillions of Dollars To Reshape Business of Chips and AI (wsj.com) 54

Sam Altman was already trying to lead the development of human-level artificial intelligence. Now he has another great ambition: raising trillions of dollars to reshape the global semiconductor industry. From a report: The OpenAI chief executive officer is in talks with investors including the United Arab Emirates government to raise funds for a wildly ambitious tech initiative that would boost the world's chip-building capacity, expand its ability to power AI, among other things, and cost several trillion dollars, according to people familiar with the matter. The project could require raising as much as $5 trillion to $7 trillion, one of the people said.

The fundraising plans, which face significant obstacles, are aimed at solving constraints to OpenAI's growth, including the scarcity of the pricey AI chips required to train large language models behind AI systems such as ChatGPT. Altman has often complained that there aren't enough of these kinds of chips -- known as graphics processing units, or GPUs -- to power OpenAI's quest for artificial general intelligence, which it defines as systems that are broadly smarter than humans. Such a sum of investment would dwarf the current size of the global semiconductor industry. Global sales of chips were $527 billion last year and are expected to rise to $1 trillion annually by 2030. Global sales of semiconductor manufacturing equipment -- the costly machinery needed to run chip factories -- last year were $100 billion, according to an estimate by the industry group SEMI.

TSMC To Build Second Japan Chip Factory, Raising Investment To $20 Billion (reuters.com) 44

Taiwanese chipmaker TSMC announced plans to build a second chip factory in Japan by the end of 2027, bringing total investment in its Japan venture to more than $20 billion. "Taiwan Semiconductor Manufacturing Co announced plans in 2021 to build a $7 billion chip plant in Kumamoto in southern Japan's Kyushu," notes Reuters. From the report: In a statement, TSMC, the world's largest contract chipmaker, said its majority-owned unit Japan Advanced Semiconductor Manufacturing in Kumamoto would build a second fabrication plant, or fab, in response to rising customer demand. The second fab will begin construction by the end of this year and with both factories the site is expected to have total monthly capacity of more than 100,000 12-inch wafers to be used for automotive, industrial, consumer and high performance computing-related applications, TSMC said. The capacity plan may be further adjusted based upon customer demand, it added.

TSMC's expansion in Kyushu is central to the Japanese government's efforts to rebuild the country's position as a leading chip manufacturing centre and ensure the stable supply of chips amid trade tensions between the United States and China. The decision to build a second fab is a vote of confidence by TSMC in Japan where construction of the first fab has run smoothly and which, Reuters has reported, it sees as a source of diligent workers with a government that is easy to deal with.

Report Reveals Decline In Quality of USB Sticks, MicroSD Cards (techspot.com) 71

A new report from German data recovery company CBL found that devices using NAND chips from reputable brands are declining in quality, with reduced capacity and their manufacturers' logo removed. Furthermore, some USB sticks use the old trick of soldiering a microSD card onto the board. TechSpot reports: Most of the janky USB sticks CBL examined were promotional gifts, the kind given away free with products or by companies at conferences. However, there were some "branded" products that fell into the same inferior-quality category, though CBL didn't say if these were well-known mainstream brands or the kind of brands you've probably never heard of.

Technological advancements have also affected these NAND chips, but not in a good way. The chips originally used single-level cell (SLC) memory cells that only stored one bit each, offering less data density but better performance and reliability. In order to increase the amount of storage the chips offered, manufacturers started moving to four bits per cell (QLC), decreasing the endurance and retention. Combined with the questionable components, it's why CBL warns that "You shouldn't rely too much on the reliability of flash memory."

The report illustrates how some of the components found in the devices had their manufactures' names removed or obscured. One simply printed text over the top of the company name, while another had been scrubbed off completely. There's also a photo of a microSD card found inside a USB stick that had all of its identifying markings removed. It's always wise to be careful when choosing your storage device and beware of offers that seem too good to be true.

Over 2 Percent of the US's Electricity Generation Now Goes To Bitcoin (arstechnica.com) 106

"In the last few years, the U.S. has seen a boom in cryptocurrency mining," writes Ars Technica. But they add that the U.S. government "is now trying to track exactly what that means for the consumption of electricity. Specifically, a crucial branch of the U.S. Department of Energy.

"While its analysis is preliminary, the Energy Information Agency (EIA) estimates that large-scale cryptocurrency operations are now consuming over 2 percent of the U.S.'s electricity." That's roughly the equivalent of having added an additional state to the grid over just the last three years."

While there is some small-scale mining that goes on with personal computers and small rigs, most cryptocurrency mining has moved to large collections of specialized hardware. While this hardware can be pricy compared to personal computers, the main cost for these operations is electricity use, so the miners will tend to move to places with low electricity rates. The EIA report notes that, in the wake of a crackdown on cryptocurrency in China, a lot of that movement has involved relocation to the U.S., where keeping electricity prices low has generally been a policy priority.

One independent estimate made by the Cambridge Centre for Alternative Finance had the US as the home of just over 3 percent of the global bitcoin mining at the start of 2020. By the start of 2022, that figure was nearly 38 percent... The EIA decided it needed a better grip on what was going on... To better understand the implications of this major new drain on the U.S. electric grid, the EIA will be performing monthly analyses of bitcoin operations during the first half of 2024.

The Energy Information Agency identified 137 bitcoin mining operators, of which 101 responded to inquiries about their full-capacity power supply. "If running all-out, those 101 facilities would consume 2.3 percent of the US's average power demand," the article points out. And they add that in at least five instances, the Agency found bitcoin operators had "moved in near underutilized power plants and sent generation soaring again...

"These are almost certainly fossil fuel plants that might be reasonable candidates for retirement if it weren't for their use to supply bitcoin miners."

IEA Lowers Renewables Forecast For Clean Hydrogen (reuters.com) 34

Although hydrogen-dedicated renewable energy capacity is expected to increase by 45 GW between 2022 and 2028, the estimates are 35% lower than what the International Energy Agency (IEA) forecasted a year ago. Reuters reports: There is growing political momentum for low-emission hydrogen but actual implementation has been held up by uncertain demand outlooks, a lack of clarity in regulatory frameworks, and a lack of infrastructure to deliver hydrogen to end users, the IEA said in an emailed response to questions. Slow progress on real-world implementation "is a consequence of barriers that could be expected in a sector that needs to build up new and complex value chains," the IEA said. Uncertainties have been exacerbated by inflation and sluggish policy implementation.

Expected renewable energy capacity for hydrogen production represents just 7% of the capacity pledged for the same period and one tenth the sum of government targets for 2030, IEA said in its report. Around 75% of expected capacity is based in three countries, with China taking the lion's share, followed by Saudi Arabia and the United States, the IEA says.

Microsoft AI Engineer Says Company Thwarted Attempt To Expose DALL-E 3 Safety Problems (geekwire.com) 78

Todd Bishop reports via GeekWire: A Microsoft AI engineering leader says he discovered vulnerabilities in OpenAI's DALL-E 3 image generator in early December allowing users to bypass safety guardrails to create violent and explicit images, and that the company impeded his previous attempt to bring public attention to the issue. The emergence of explicit deepfake images of Taylor Swift last week "is an example of the type of abuse I was concerned about and the reason why I urged OpenAI to remove DALL-E 3 from public use and reported my concerns to Microsoft," writes Shane Jones, a Microsoft principal software engineering lead, in a letter Tuesday to Washington state's attorney general and Congressional representatives.

404 Media reported last week that the fake explicit images of Swift originated in a "specific Telegram group dedicated to abusive images of women," noting that at least one of the AI tools commonly used by the group is Microsoft Designer, which is based in part on technology from OpenAI's DALL-E 3. "The vulnerabilities in DALL-E 3, and products like Microsoft Designer that use DALL-E 3, makes it easier for people to abuse AI in generating harmful images," Jones writes in the letter to U.S. Sens. Patty Murray and Maria Cantwell, Rep. Adam Smith, and Attorney General Bob Ferguson, which was obtained by GeekWire. He adds, "Microsoft was aware of these vulnerabilities and the potential for abuse."

Jones writes that he discovered the vulnerability independently in early December. He reported the vulnerability to Microsoft, according to the letter, and was instructed to report the issue to OpenAI, the Redmond company's close partner, whose technology powers products including Microsoft Designer. He writes that he did report it to OpenAI. "As I continued to research the risks associated with this specific vulnerability, I became aware of the capacity DALL-E 3 has to generate violent and disturbing harmful images," he writes. "Based on my understanding of how the model was trained, and the security vulnerabilities I discovered, I reached the conclusion that DALL-E 3 posed a public safety risk and should be removed from public use until OpenAI could address the risks associated with this model."

On Dec. 14, he writes, he posted publicly on LinkedIn urging OpenAI's non-profit board to withdraw DALL-E 3 from the market. He informed his Microsoft leadership team of the post, according to the letter, and was quickly contacted by his manager, saying that Microsoft's legal department was demanding that he delete the post immediately, and would follow up with an explanation or justification. He agreed to delete the post on that basis but never heard from Microsoft legal, he writes. "Over the following month, I repeatedly requested an explanation for why I was told to delete my letter," he writes. "I also offered to share information that could assist with fixing the specific vulnerability I had discovered and provide ideas for making AI image generation technology safer. Microsoft's legal department has still not responded or communicated directly with me." "Artificial intelligence is advancing at an unprecedented pace. I understand it will take time for legislation to be enacted to ensure AI public safety," he adds. "At the same time, we need to hold companies accountable for the safety of their products and their responsibility to disclose known risks to the public. Concerned employees, like myself, should not be intimidated into staying silent."

Japan Will No Longer Require Floppy Disks For Submitting Some Official Documents (engadget.com) 45

Japan is aiming to phase out floppy disks and CD-ROMs, which until now were forms of physical media required for submitting some official documents to the government. Engadget reports: Back in 2022, Minister of Digital Affairs Taro Kono urged various branches of the government to stop requiring businesses to submit information on outdated forms of physical media. The Ministry of Economy, Trade and Industry (METI) is one of the first to make the switch. "Under the current law, there are many provisions stipulating the use of specific recording media such as floppy disks regarding application and notification methods," METI said last week, according to The Register. After this calendar year, METI will no longer require businesses to submit data on floppy disks under 34 ordinances. The same goes for CD-ROMs when it comes to an unspecified number of procedures. There's still quite some way to go before businesses can stop using either format entirely, however.

Kono's staff identified some 1,900 protocols across several government departments that still require the likes of floppy disks, CD-ROMs and even MiniDiscs. The physical media requirements even applied to key industries such as utility suppliers, mining operations and aircraft and weapons manufacturers. There are a couple of main reasons why there's a push to stop using floppy disks, as SoraNews24 points out. One major factor is that floppy disks can be hard to come by. Sony, the last major manufacturer, stopped selling them in 2011. Another is that some data types just won't fit on a floppy disk. A single photo can easily be larger than the format's 1.4MB storage capacity.

Blackstone Is Building a $25 Billion Empire of Power-Hungry Data Centers (bloomberg.com) 23

Blackstone is betting big on AI, plowing billions into data centers after its $10 billion takeover of QTS last year. The private equity giant is bankrolling the development of massive computing bunkers on hundreds of acres in Phoenix and other key markets to meet exploding demand from tech titans like Microsoft. With AI taking hold, QTS has become North America's top provider of leased data center capacity. But the data crunch has strained power grids. QTS estimates its data centers will tap 6 gigawatts of electricity, equal to the needs of 5 million homes.

Climate Change Cripples Panama Canal. Fixing it Could Take Years (yahoo.com) 148

"Parched conditions have crippled a waterway that handles $270 billion a year in global trade," reports Bloomberg. "And there are no easy solutions.

"The Panama Canal Authority is weighing potential fixes that include an artificial lake to pump water into the canal and cloud seeding to boost rainfall, but both options would take years to implement, if they're even feasible. " With water levels languishing at six feet (1.8 meters) below normal, the canal authority capped the number of vessels that can cross. The limits imposed late last year were the strictest since 1989... Some shippers are paying millions of dollars to jump the growing queue, while others are taking longer, costlier routes around Africa or South America. The constraints have since eased slightly due to a rainier-than-expected November, but at 24 ships a day, the maximum is still well below the pre-drought daily capacity of about 38. As the dry season takes hold, the bottleneck is poised to worsen again...

The canal's travails reflect how climate change is altering global trade flows. Drought created chokepoints last year on the Mississippi River in the US and the Rhine in Europe. In the UK, rising sea levels are elevating the risk of flooding along the Thames. Melting ice is creating new shipping routes in the Arctic. Under normal circumstances, the Panama Canal handles about 3% of global maritime trade volumes and 46% of containers moving from Northeast Asia to the US East Coast...

In the long term, the primary solution to chronic water shortages will be to dam up the Indio River and then drill a tunnel through a mountain to pipe fresh water 8 kilometers (5 miles) into Lake Gatún, the canal's main reservoir. The project, along with additional conservation measures, will cost about $2 billion, Erick Córdoba, the manager of the water division at the canal authority estimates. He says it will take at least six years to dam up and fill the site. The US Army Corps of Engineers is conducting a feasibility study. The Indio River reservoir would increase vessel traffic by 11 to 15 a day, enough to keep Panama's top moneymaker working at capacity while guaranteeing fresh water for Panama City...

The country will need to dam even more rivers to guarantee water through the end of the century.

Lamborghini Licenses MIT's New High-Capacity, Fast-Charging Organic Battery Tech (techradar.com) 81

An anonymous reader quotes a report from TechRadar: Thanks to new Massachusetts Institute of Technology (MIT) research, which was part-funded by Lamborghini, we could soon see the end of difficult-to-source and often problematic rare metal materials featuring in the batteries of future electric vehicles. The MIT study's aim was to replace cobalt and nickel, typically used as a cathode in today's lithium-ion battery technology, with organic materials that could be produced at a much lower cost. This would also reduce the impact on the planet and conduct electricity at similar rates as cobalt batteries. [...] The research, which has been running for six years, has culminated in a novel organic material that could be a direct replacement for cobalt and nickel. According to details recently released by MIT, this material consists of many layers of TAQ (bis-tetraaminobenzoquinone), an organic small molecule that contains three fused hexagonal rings.

It's a complicated subject for those not donning lab coats for a living, but these TAQ layers can extend outward in every direction, forming a structure similar to graphite. Within the molecules are chemical groups called quinones, which are the electron reservoirs, and amines, which help the material to form strong hydrogen bonds, which ensure they don't dissolve into the battery electrolyte (something that has previously blighted organic cathode compounds), thus extending the lifetime of the battery. It comes as no surprise that Lamborghini has licensed the patent on this technology, seeing as it funded the research and has a certain Lanzador high performance electric vehicle in the pipeline.

Researchers say that tests of the material revealed that its conductivity and storage capacity were comparable to that of traditional cobalt-containing batteries. Also, batteries with a TAQ cathode can be charged and discharged faster than existing batteries, which could speed up the charging rate for electric vehicles. This speedy rate of charge and discharge could help give something like Lamborghini's Lanzador a performance edge, while super-fast charging capabilities will negate the need for lengthy charging stops -- something the Italian marque's discerning clientele will likely be opposed to. However, Lamborghini is also part of the wider Volkswagen Group and seeing that the primary materials needed to manufacture this type of cathode are already commercially available and produced in large quantities as commodity chemicals, we may see the battery tech filter down to more affordable EVs in the future.

OpenAI Ceo Sam Altman Is Still Chasing Billions To Build AI Chips 11

According to Bloomberg (paywalled), OpenAI CEO Sam Altman is reportedly raising billions to develop a global network of chip fabrication factories, collaborating with leading chip manufacturers to address the high demand for chips required for advanced AI models. The Verge reports: A major cost and limitation for running AI models is having enough chips to handle the computations behind bots like ChatGPT or DALL-E that answer prompts and generate images. Nvidia's value rose above $1 trillion for the first time last year, partly due to a virtual monopoly it has as GPT-4, Gemini, Llama 2, and other models depend heavily on its popular H100 GPUs.

Accordingly, the race to manufacture more high-powered chips to run complex AI systems has only intensified. The limited number of fabs capable of making high-end chips is driving Altman or anyone else to bid for capacity years before you need it in order to produce the new chips. And going against the likes of Apple requires deep-pocketed investors who will front costs that the nonprofit OpenAI still can't afford. SoftBank Group and Abu Dhabi-based AI holding company G42 have reportedly been in talks about raising money for Altman's project.

30TB Hard Drives Are Nearly Here (tomshardware.com) 74

Seagate this week unveiled the industry's first hard disk drive platform that uses heat-assisted media recording (HAMR). Tom's Hardware: The new Mozaic 3+ platform relies on several all-new technologies, including new media, new write and read heads, and a brand-new controller. The platform will be used for Seagate's upcoming Exos hard drives for cloud datacenters with a 30TB capacity and higher. Heat-assisted magnetic recording is meant to radically increase areal recording density of magnetic media by making writes while the recording region is briefly heated to a point where its magnetic coercivity drops significantly.

Seagate's Mozaic 3+ uses 10 glass disks with a magnetic layer consisting of an iron-platinum superlattice structure that ensures both longevity and smaller media grain size compared to typical HDD platters. To record the media, the platform uses a plasmonic writer sub-system with a vertically integrated nanophotonic laser that heats the media before writing. Because individual grains are so small with the new media, their individual magnetic signatures are lower, whereas magnetic inter-track interference (ITI) effect is somewhat higher. As a result, Seagate had to introduce its new Gen 7 Spintronic Reader, which features the "world's smallest and most sensitive magnetic field reading sensors," according to the company. Because Seagate's new Mozaic 3+ platform deals with new media with a very small grain size, an all-new writer, and a reader that features multiple tiny magnetic field readers, it also requires a lot of compute horsepower to orchestrate the drive's work. Therefore, Seagate has equipped with Mozaic 3+ platform with an all-new controller made on a 12nm fabrication process.

Google CEO Tells Employees To Expect More Job Cuts This Year (theverge.com) 53

Google has laid off over a thousand employees across various departments since January 10th. CEO Sundar Pichai's message is to brace for more cuts. The Verge: "We have ambitious goals and will be investing in our big priorities this year," Pichai told all Google employees on Wednesday in an internal memo that was shared with me. "The reality is that to create the capacity for this investment, we have to make tough choices." So far, those "tough choices" have included layoffs and reorganizations in Google's hardware, ad sales, search, shopping, maps, policy, core engineering, and YouTube teams.

"These role eliminations are not at the scale of last year's reductions, and will not touch every team," Pichai wrote in his memo -- a reference to when Google cut 12,000 jobs this time last year. "But I know it's very difficult to see colleagues and teams impacted." Pichai said the layoffs this year were about "removing layers to simplify execution and drive velocity in some areas." He confirmed what many inside Google have been fearing: that more "role eliminations" are to come. "Many of these changes are already announced, though to be upfront, some teams will continue to make specific resource allocation decisions throughout the year where needed, and some roles may be impacted," he wrote.

World's First Floating Offshore Wind Farm To Be Taken Offline For Up To 4 Months (electrek.co) 142

An anonymous reader quotes a report from Electrek: The world's first floating offshore wind farm, Hywind Scotland, is coming offline for three to four months for "heavy maintenance." Hywind Scotland's operator, Norwegian power giant Equinor, says that operational data has indicated that its wind turbines need work. The pilot project has been in operation since 2017. The five Siemens Gamesa turbines will be towed to Norway this summer. An Equinor spokesperson said, "This is the first such operation for a floating farm, and the safest method to do this is to tow the turbines to shore and execute the operations in sheltered conditions."

Norwegian contractor Wergeland Group will undertake the work. The spokesperson added, "Wergeland is the closest port with offshore wind experience and sufficient water depth that can service these turbines." As the world's first floating offshore wind farm, Hywind Scotland has trailblazed for much larger floating wind farms now in the pipeline. Its five floating wind turbines have a total capacity of 30 megawatts (MW). It generates enough electricity to power the equivalent of 34,000 households in the UK. Each turbine's maximum height, base to turbine, is 253 meters (830 feet). [...] Equinor said in December 2022, when Hywind Scotland turned five, that it was the world's best-performing offshore wind farm, achieving a capacity factor of 54% over its five years of operations.

Why a School Principal Switched from Smartphones to Flip Phones (msn.com) 90

Last week's story about a reporter switching to a flip phone was just part of a trend, argues a Chicago school principal who did the same thing.

"I do not feel punished. I feel free." Teachers said they could sense kids' phones distracting them from inside their pockets. We banned phones outright, equipping classrooms with lockboxes that the kids call "cellphone prisons." It's not perfect, but it's better. A teacher said, "It's like we have the children back...."

And what about adults? Ninety-five percent of young adults now keep their phones nearby every waking hour, according to a Gallup survey; 92% do when they sleep. We look at our phones an average of 352 times a day, according to one recent survey, almost four times more often than before COVID. We want children off their phones because we want them to be present, but children need our presence, too. When we are on our phones, we are somewhere else. As the title of one study notes, "The Mere Presence of One's Own Smartphone Reduces Available Cognitive Capacity...."

I made my screen gray. I deleted social media. I bought a lockbox and said I would keep my phone there. I didn't... Every year, I see kids get phones and disappear into them. I don't want that to happen to mine. I don't want that to have happened to me. So I quit. And now I have this flip phone.

What I don't have is Facetime or Instagram. I can't use Grubhub or Lyft or the Starbucks Mobile App. I don't even have a browser. I drove to a student's quinceañera, and I had to print out directions as if it were 2002... I can still make calls, though people are startled to get one. I can still text. And I can still see your pictures, though I can "heart" them only in my heart. The magic of smartphones is that they eliminate friction: touchscreens, auto-playing videos, endless scrolling. My phone isn't smooth.

That breaks the spell. Turning off my smartphone didn't fix all my problems. But I do notice my brain moving more deliberately, shifting less abruptly between moods. I am bored more, sure — the days feel longer — but I am deciding that's a good thing. And I am still connected to the people I love; they just can't text me TikToks...

I'm not doing this to change the culture. I'm doing this because I don't want my sons to remember me lost in my phone.

A Huge Battery Has Replaced Hawaii's Last Coal Plant (canarymedia.com) 122

Julian Spector reports via Canary Media: Hawaii shut down its last coal plant on September 1, 2022, eliminating 180 megawatts of fossil-fueled baseload power from the grid on Oahu -- a crucial step in the state's first-in-the-nation commitment to cease burning fossil fuels for electricity by 2045. But the move posed a question that's becoming increasingly urgent as clean energy surges across the United States: How do you maintain a reliable grid while switching from familiar fossil plants to a portfolio of small and large renewables that run off the vagaries of the weather? Now Hawaii has an answer: It's a gigantic battery, unlike the gigantic batteries that have been built before.

The Kapolei Energy Storage system actually began commercial operations before Christmas on the industrial west side of Oahu, according to Plus Power, the Houston-based firm that developed and owns the project. Now, Kapolei's 158 Tesla Megapacks are charging and discharging based on signals from utility Hawaiian Electric. The plant's 185 megawatts of instantaneous discharge capacity match what the old coal plant could inject into the grid, though the batteries react far more quickly, with a 250-millisecond response time. Instead of generating power, they absorb it from the grid, ideally when it's flush with renewable generation, and deliver that cheap, clean power back in the evening hours when it's desperately needed.

The construction process had its setbacks, as did the broader effort to replace the coal plant with a roster of large-scale clean energy projects. The Kapolei battery was initially intended to come online before the coal plant retired. Covid disrupted deliveries for the grid battery industry across the board, and Kapolei's remote location in the middle of the Pacific Ocean didn't make things easier. By summer 2021, Plus Power was hoping to complete Kapolei by the end of 2022, but it ended up taking another year. Even then, it has joined the grid before several of the other large solar and battery projects slated to replace the coal plant's production with clean power.

Microsoft's New Battery is a Test of AI-Infused Scientific Discovery (fastcompany.com) 29

Harry McCracken, writing for FastCompany: Recently, Microsoft built a clock. Well, "built" may be overstating things. Members of the company's quantum computing team found a small digital clock in a wood case on Amazon -- the kind you might mistake for a nicer-than-usual trade show tchotchke. They hacked it to run off two experimental batteries they'd created in collaboration with staffers at the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL). Then they dressed up its enclosure by adding the logo of Azure Quantum Elements, the Microsoft platform for AI-enhanced scientific discovery that had been instrumental in developing the new battery technology.

The point of this little DIY project was to prove the batteries worked in a visceral way: "You want to have a wow moment," explains Brian Bilodeau, the head of partnerships, strategy, and operations for Azure Quantum. And the person the quantum team hoped to wow was Microsoft CEO Satya Nadella. Not that getting Nadella's attention was such a daunting prospect. Throwing vast amounts of Azure high-performance computing (HPC) resources at a big, hairy technical challenge such as materials research is the sort of challenge he's predisposed to take a personal interest in. Still, the tangible evidence of success made for a memorable moment: "I was very, very excited to see it come through," Nadella remembers.

The coin-sized CR2032 batteries powering the clock looked like the ones you might find in a pocket calculator or garage door opener. But on the inside, they used a solid-state electrolyte that replaces 70% of the lithium in garden-variety batteries with sodium. That holds the potential to address multiple issues with lithium batteries as we know them: their limited life on a charge, shrinking capacity over time, subpar performance in extreme temperatures, and risk of catching fire or even exploding. In addition, reducing lithium use in favor of cheap, plentiful sodium could be a boon to the fraught battery supply chain. With further development, the new material could benefit the myriad aspects of modern life that depend on batteries, from smartphones to EVs to the power grid. But Microsoft, being Microsoft, regards all this promise first and foremost as proof of Azure Quantum Elements' usefulness to the customers it's designed to serve. Unveiled last June, the cloud service is currently a "private preview" being tested by organizations such as Britain's Johnson Matthey, which is using it to help design catalytic converters and hydrogen fuel cells.
