Blue Origin's Stay of SpaceX's Moon Lander Contract Gets One-Week Extension Thanks to...PDF Files (mashable.com) 80

Earlier this month Jeff Bezos' Blue Origin sued NASA over a moon lander contract awarded to SpaceX.

Now Mashable reports that "America's next trip to the moon may suddenly be delayed a bit thanks to...PDFs?" A U.S. federal judge has granted the Department of Justice a week-long extension in its lawsuit with Jeff Bezos' space company Blue Origin. The reason? Large PDF files...

According to the DOJ, there is more than 7 GB of data related to the case. However, the U.S. Court of Federal Claims' online system allows for only files of up to 50 MB in size to be uploaded. This all amounts to "several hundred" PDFs, including other file formats that would be converted to PDFs. The DOJ says it also sought to convert multiple separate documents into individual PDF batches but explained that those larger files could cause the upload system to crash. "We have tried several different ways to create 50-megabyte files for more efficient filing, all without success thus far," the DOJ said.

Instead of using the online file system, the U.S. government will transfer the documents for the case to DVDs.

Futurism reports the situation was exacerbated "because the agency staff that could have fixed the issue were at the 36th Annual Space Symposium last week."

On Twitter, space reporter Joey Roullete notes the judge's ruling means an additional one-week stay before the awarding of SpaceX's contract..

Or, as Mashable puts it, "Space exploration is currently on hold thanks to a lawsuit and a slew of pesky PDF files."

So How Close Are We Now to Nuclear Fusion Energy? (theguardian.com) 180

For a fraction of a second, 10 quadrillion watts of fusion power were produced this month by researchers at Lawrence Livermore National Laboratory.

The author of The Star Builders: Nuclear Fusion and the Race to Power the Planet explains what might happen next: The aim of these experiments is — for now — to show proof of principle only: that energy can be generated. The team behind the success are very close to achieving this: they have managed a more than 1,000-fold improvement in energy release between 2011 and today. Prof Jeremy Chittenden, co-director of the Centre for Inertial Fusion Studies at Imperial College London, said last month that "The pace of improvement in energy output has been rapid, suggesting we may soon reach more energy milestones, such as exceeding the energy input from the lasers used to kickstart the process...."

Many recent advances have been made with a different type of fusion device, the tokamak: a doughnut-shaped machine that uses a tube of magnetic fields to confine its fuel for as long as possible. China's Experimental Advanced Superconducting Tokamak (East) set another world record in May by keeping fuel stable for 100 seconds at a temperature of 120m degrees celsius — eight times hotter than the sun's core. The world's largest ever magnetic fusion machine, Iter, is under construction in the south of France and many experts think it will have the scale needed to reach net energy gain. The UK-based Joint European Torus (Jet), which holds the current magnetic fusion record for power of 67%, is about to attempt to produce the largest total amount of energy of any fusion machine in history. Alternative designs are also being explored: the UK government has announced plans for an advanced tokamak with an innovative spherical geometry, and "stellarators", a type of fusion device that had been consigned to the history books, are enjoying a revival having been enabled by new technologies such as superconducting magnets.

This is a lot of progress, but it's not even the biggest change: that would be the emergence of private sector fusion firms. The recently formed Fusion Industry Association estimates that more than $2bn of investment has flooded into fusion startups. The construction of experimental reactors by these firms is proceeding at a phenomenal rate: Commonwealth Fusion Systems, which has its origins in MIT research, has begun building a demonstration reactor in Massachusetts; TAE Technologies has just raised $280m to build its next device; and Canadian-based General Fusion has opted to house its new $400m plant in the UK. This will be constructed in Oxfordshire, an emerging hotspot for the industry that is home to private ventures First Light Fusion and Tokamak Energy as well as the publicly funded Jet and Mast (Mega Amp Spherical Tokamak) Upgrade devices run by the UK Atomic Energy Authority...

For now, publicly funded labs are producing results a long way ahead of the private firms — but this could change.

"Whether commercial fusion energy is ready in time to help with global warming or not depends on us as a society and how badly we want — no, need — star power on our side," the author concludes.

He also calls fusion energy "the only feasible way we can explore space beyond Earth's immediate vicinity."

Bitcoin-Mining Power Plant Secretly Launched in Alberta, Tapping Dormant Gas Well (www.cbc.ca) 62

"When residents of an affluent estate community in Alberta started hearing noise from a nearby power plant, they didn't expect their complaints of sleepless nights would lead to a months-long investigation that would find a bitcoin mining operation had set up shop without approval," reports the CBC: Now, Link Global, the company behind the site, is being ordered by the province's utility commission to shut down two plants until it can prove it's allowed to operate — a move the company says will cost jobs and cause the oil and gas infrastructure in which it operates to sit dormant....

Vancouver-based Link Global had set up four 1.25 MW gas generators at the site, pulling power from a dormant natural gas well owned by Calgary-based company MAGA Energy. The natural gas powers thousands of computer servers that run programs to "mine" digital currency... Work on the plant began in August 2020, and by fall — when neighbours started to get annoyed — it was operating at full capacity. There was just one problem: The company hadn't notified neighbours of its plans. Or the county. Or the provincial utilities commission — which allows power plants to be set up without approval if they meet several conditions, including only generating power for the company's own use and proving the plant has no adverse effects on people or the environment...

Alberta is littered with nearly 200,000 dormant or abandoned oil and gas wells, often because they're no longer economically viable. It has raised the spectre that landowners and taxpayers could be on the hook for the cleanup costs, which the province estimates could be up to $30 billion, as well as prompted a push to find other uses for the facilities, such as powering cryptocurrency operations. Stephen Jenkins, Link Global's CEO, said some of that abandoned energy infrastructure, is at risk of leaking methane — a greenhouse gas more potent than carbon dioxide. "We look at, OK, what can we do to use this in a beneficial way ... I don't want to say we're in the business of methane destruction, but we're in the business of beneficial use of that potential methane-generating source. You combust it properly. You don't flare it, and you control those emissions," Jenkins said...

And though the facility employs only four people, Jenkins said it's important to him to employ locally and give former oil and gas workers a path into other careers. The Sturgeon County plant's supervisor is a former pipefitter; he's now a bitcoin pro and an expert at keeping the plant online, Jenkins said. "It's a perfect use of people's skills," he said.

Of course, it's not all altruism. The company has said for every 10 MW of power, it can generate about 1.2 bitcoins per day.

Last Friday the Alberta Utilities Commission (AUC) ruled that the plant had indeed been violating their regulatory requirements, and would now also have to suffer a financial penalty which the CBC reported as "a $50,000 to $75,000 fine, reduced by up to 50% because Link Global admitted to breaking the rules..."

"More penalties could be on the way. The AUC will now review whether specific sanctions should be imposed against Link Global for operating without approval — a decision on that is expected this fall."

The CBC adds that another Link Global plant was also found to be "set up without the AUC's prior approval."

Samsung Is the Latest SSD Manufacturer Caught Cheating Its Customers (extremetech.com) 53

Crucial and Western Digital have recently been caught swapping the TLC NAND used for certain products with inferior QLC NAND without updating product SKUs or informing reviewers of this change. Now, Samsung was caught doing something similar. Samsung is "swapping the drive controller + TLC for a different, inferior drive controller," according to ExtremeTech. "The net effect is still a steep performance decline in certain tests." From the report: The other beats of this story are familiar. Computerbase.de reports on a YouTube Channel, which compared two different versions of the Samsung 970 Plus. Both drives are labeled with the same sticker declaring them to be a 970EVO Plus, but the part numbers are different. One drive is labeled the MZVLB1T0HBLR (older, good) and one is the MZVL21T0HBLU (newer, inferior). Peel the sticker back, and the chips underneath are rather different. The Phoenix drive (top) is older than the Elpis drive on the bottom. Computerbase claims a production date of April 2021 for the Phoenix, but if the 2110 and 2123 codes are production dates, this would seem to indicate March and June. It's possible that Samsung uses specific numerical codes for each month. Either way, the Phoenix drive is older and faster and the Elpis drive is newer and slower.

And -- just as we've seen from Crucial and Western Digital -- performance in some benchmarks after the swap is just fine, while other benchmarks crater. [...] The original 970 Plus starts with solid performance and holds it for the entire 200GB test. The right-hand SSD is even faster than the OG 970 Plus until we hit the 120GB mark, at which point performance drops to 50 percent of what it was. Real-world file copies also bear this out, with one drive holding 1.58GB/s and one at 830MB/s. TLC hasn't been swapped for QLC, but the 50 percent performance hit in some tests is as bad as what we see when it has been.

Tesla Files To Become an Electricity Provider in Texas (cnbc.com) 64

Tesla wants to sell electricity directly to customers in Texas, according to an application filed by the company this month with the Public Utility Commission there. From a report: The application follows the start of a big battery build out by Tesla in Angleton, Texas (near Houston), where it aims to connect a 100 megawatt energy storage system to the grid. Texas Monthly first reported on the application, submitted by a wholly owned subsidiary of Tesla called Tesla Energy Ventures. Tesla has also built several utility-scale energy storage systems around the world, including one east of Los Angeles, another underway in Monterey, California, and two in Australia -- one in Geelong, Victoria, and another in Adelaide, South Australia.

Scientists Reveal World's First 3D-Printed, Marbled Wagyu Beef (interestingengineering.com) 107

Scientists from Osaka University have manufactured the world's first 3D-printed Wagyu beef by using stem cells isolated from Japanese cattle, according to a press release. The product looks like a realistic steak piece containing muscle, fat, and blood vessels. Interesting Engineering reports: Because of its high marble content, Wagyu (Japanese cow) beef is one of the most sought-after and expensive meats in the world. Marbling, or sashi in Jaoan, refers to the visible layers of intramuscular fat that give the beef its rich flavors and distinctive texture, and because most cultured meats produced thus far resemble mince composed of simple muscle fibers rather than the complex structure of real beef steaks, 3D printing Wagyu is an extremely difficult feat.

The researchers used two types of stem cells, bovine satellite cells and adipose-derived stem cells, insulated from Wagyu cows, according to the paper published in the journal Nature Communications. Then, they incubated and coaxed the cells into becoming the various cell types required to generate individual fibers for muscle, fat, and blood vessels. These were piled into a 3D stack to resemble the marbling of Wagyu. Then, the researchers adapted a technique inspired by the one used to produce Japanese Kintaro candy, an old traditional sweet formed in a long pipe and cut into slices. The stacks were sliced perpendicularly to form lab-grown beef slices, which allowed a great degree of customization within the complex meat structure. This was how they were able to mimic the famous texture of Wagyu. According to the researchers, the synthetic meat "looks more like the real thing" and the process can be used to create other complex structures.

Western Digital Caught Bait-and-Switching Customers With Slow SSDs (extremetech.com) 92

An anonymous reader quotes a report from ExtremeTech, written by Joel Hruska: According to a report from Chinese tech site Expreview, the WD SN550 Blue -- which is currently one of the best-reviewed budget SSDs on the market -- has undergone a NAND lobotomy. While the new SSD variant performs on-par with the old drive that WD actually sampled for review, once you exhaust the SLC NAND cache, performance craters from 610MB/s to 390MB/s. The new drive offers just 64 percent of the performance of the old drive.

This is unacceptable. It is unethical for any company to sample and launch a product to strong reviews only to turn around and sell an inferior version of that hardware at a later date without changing the product SKU or telling customers that they're buying garbage. I do not use the term "garbage" lightly, but let me be clear: If you silently change the hardware components you use in a way that makes your product lose performance, and you do not disclose that information prominently to the customer (ideally through a separate SKU), you are selling garbage. There's nothing wrong with selling a slower SSD at a good price, and there's nothing right about abusing the goodwill of reviewers and enthusiasts to kick bad hardware out the door.

As a reviewer of some twenty years, I do not care at all about the fact that SLC cache performance is identical. While I didn't realize it at the time I wrote up the Crucial bait-and-switch on August 16, I've actually been affected by this problem personally. The 2TB Crucial SSD I purchased for my own video editing work is one of the bait-and-switched units, and it's always had a massive performance problem -- as soon as it empties the SLC cache, it falls to what I'd charitably call hard drive-level performance. Performance can drop as low as 60MB/s via USB3.2 (and ~150MB/s when directly connected via NVMe) and it stays there until the copy task is done. The video upscaling projects I work on regularly generate between 300-500GB of image data per episode, per encode. Achieving ideal results can require weaving the output of 3-5 models together. That means I generate up to 1.5TB of data to create a single episode. God help you if you need to copy that much information to or from one of these broken SSDs. It's not literally as bad as a spinning disk from circa 2003, but it's nowhere near acceptable performance.

TSMC Hikes Chip Prices Up To 20% Amid Supply Shortage (nikkei.com) 55

Contract chipmaking giant Taiwan Semiconductor Manufacturing told has told that it plans to raise prices on products by as much as 20%, in what would be the company's steepest single increase. From a report: The price increases and the time frames for the hikes differ depending on the client, according to reports by Taiwan's Liberty Times newspaper and other media outlets. For some companies that received TSMC's notice, the hikes took effect immediately. TSMC and other Taiwanese semiconductor companies raised chip prices by more than 10% between last fall and this spring. But with strong demand continuing to outstrip supply, TSMC decided to sharply increase prices again. The increased costs tied to ramping up production are being passed downstream, with the company enjoying better bargaining power amid the global chip crunch as well. This move likely will impact the sticker prices of end products. A TSMC spokesperson declined to comment to Nikkei about the higher chip prices. Concerns over lower profitability are another reason behind the price hikes. The company has said it will make $100 billion in capital investments over three years through 2023. That commitment has fueled qualms about a potential decline in profits as TSMC prepares to boost its overseas expansion.

The World's First 3D-Printed Steel Bridge (popularmechanics.com) 40

An anonymous reader quotes a report from Popular Mechanics, written by Laura Rider: After four long years of planning, the world's first 3D-printed steel bridge debuted in Amsterdam last month. If it stands up to the elements, the bridge could be a blueprint for fixing our own structurally deficient infrastructure in the U.S. -- and we sorely need the help. Dutch Company MX3D built the almost 40-foot-long bridge for pedestrians and cyclists to cross the city's Oudezijds Achterburgwal canal. It relied on four robots, fit with welding torches, to 3D-print the structure. To do it, the machines laid out 10,000 pounds of steel, heated to 2,732 degrees Fahrenheit, in an intricate layering process. The result? An award-winning design, pushing the boundaries of what steel can do.

Designers first came up with the concept for the bridge in 2015, with the goal of making an exceptionally efficient structure. To do so, they had to emphasize two things: simplicity and safety. To monitor the efficiency of their design, scientists at Imperial College London engineered the bridge to be a "living laboratory." A team of structural engineers, computer scientists, and statisticians developed a system of over one dozen embedded sensors for the bridge, which send live data to the university for further analysis of the bridge's performance. They monitor the bridge's movement, vibration, temperature, strain (the change in shape and size of materials under applied forces), and displacement (the amount an object shifts in a specific direction) over time. From that data, scientists built a "digital twin" -- computer science parlance for an identical, virtual rendering -- of the bridge that gets more accurate over time. With machine learning, they can now look for trends that might suggest modifications are in order.

For this bridge, designers utilized two methods of 3D printing -- Direct Energy Deposit (DED) and Powder Bed Fusion (PBF). With DED, the printer feeds material (typically in powder or wire form) through a pen-like nozzle, and an intense heat source (typically a laser, but sometimes an electron beam) melts the metal on contact. PBF works similarly in that a laser or electron beam melts powder down to build each layer. The main advantage of PBF, though, is that it operates with much smaller (and more expensive) parts, resulting in a higher-resolution project than DED could accomplish on its own. This allows designers to take their visions a step further.

US PC Market Grows 17% In Q2 2021 As Notebook Popularity Booms (zdnet.com) 17

According to analysts at Canalys, the PC market in the United States is booming. Sales in Q2 2021 have grown 17% with 36.8 million units shipped. "Notebooks and desktops led the way with a growth in shipments of 27% and 23% respectively compared to last year," reports ZDNet. From the report: HP was the leading company in the US, delivering more than 8 million devices to customers and dominating the Chromebook sector with a 42% market share. Apple suffered a 3% decline in devices shipped but still held on to the second place slot behind HP. Canalys noted that Apple was the only major PC manufacturer to see negative growth in Q2, due in no small part to waning consumer interest in iPads, according to the report. The company did see a 24% increase in notebook shipments thanks to recent success with the M1 chip.

The rest of the list is rounded out by Samsung, which saw a 51% growth in shipments year over year while Lenovo and Dell posted 25% and 11% growth respectively in Q2. Canalys attributed Lenovo's success to its growing influence over the Chromebook market while Samsung solidified its place in the tablet market, seeing a growth of 19% in the US for Q2 even as the overall tablet market shrank. [Tablet shipments were down 1% in Q2.] Following a spike in tablet interest in Q2 2020, there has been a slowdown as the COVID-19 pandemic has waned and more people spent the summer outdoors.

Misaligned Factory Robot May Have Sparked Chevy Bolt Battery Fires (arstechnica.com) 42

An anonymous reader quotes a report from Ars Technica, written by Tim De Chant: GM announced last Friday that it was recalling every Chevrolet Bolt it had ever made, including the new electric utility vehicle model that debuted this year. After a string of fires affected Bolt models, the company traced the problem to two simultaneously occurring defects in the cars' LG Chem-made batteries. The automaker initially discovered the problem in batteries from one of LG's Korean plants, and it recalled cars with those cells last November. But then more Bolts caught fire, and other LG plants were ensnared in the investigation, spurring two expansions of the recall. The problem, GM said, has been traced to a torn anode tab and a folded separator.

That's all GM has said so far. It hasn't said how widespread the defects are, nor has it said how, exactly, the fires started. But in what little information has been released, and in the timing of GM's recalls, there are clues. To decipher them, Ars spoke with Greg Less, technical director of the University of Michigan's Battery Lab. "What we're looking at is a perfect storm," Less said. The Bolt's battery packs are made up of pouch-type cells, which are essentially layers of cathodes, anodes, and separators that are flooded with liquid electrolyte and encased in a flexible polymer pouch. The torn anode tab, he said, would create a projection in what should be an otherwise flat battery. The projection brings the anode closer to the cathode. "And that would probably be OK if the separator was where it was supposed to be," he said.

But in problematic Bolt batteries, the separator wasn't where it was supposed to be. Separators are placed between the anode and cathode to prevent the two electrodes from touching. A torn tab wouldn't necessarily be an issue on its own because the separator would prevent any projection from bridging the anode-cathode gap. In cells with a folded separator, though, the gap would be missing from at least part of the battery. If the anode bridges the gap, Less said, "you have a short, and it's all downhill from there." "It wouldn't surprise me if both defects are caused by the same thing," he added. "I would imagine that the separator must be folded at the edge near where the anode tab is at. What I'm guessing is that at some point during the handling of the cell, before it's fully packaged, some part of the robot machine is catching. The tab is catching, the separator is catching -- something is catching very infrequently so that it hasn't been noticed, and it's causing this damage."

Western Digital in Advanced Talks To Merge With Japan's Kioxia Holdings (reuters.com) 15

Western Digital is in advanced talks for a potential $20 billion stock merger with Japanese semiconductor firm Kioxia Holdings, the Wall Street Journal reported on Wednesday, citing people familiar with the matter. Reuters: The companies could reach an agreement as early as mid-September, and Western Digital Chief Executive Officer David Goeckeler would run the combined firm, the report said. The news sent Western Digital's shares up as much as 15% in afternoon trading to a market cap of $21.45 billion. Kioxia Holdings, the world's second-largest maker of flash memory chips, last year shelved plans for what would have been Japan's largest initial public offering in 2020. In June, however, financial magazine Diamond said the company was planning an IPO as early as September.

Dust-Sized Supercapacitor Packs the Same Voltage As a AAA Battery (newatlas.com) 135

Scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. It's smaller than a speck of dust, safe for use in the human body, and can deliver similar voltage to a AAA battery. Prior to this breakthrough, the smallest "biosupercapacitors" developed to date were 3mm^3. New Atlas reports: The construction starts with a stack of polymeric layers that are sandwiched together with a light-sensitive photo-resist material that acts as the current collector, a separator membrane, and electrodes made from an electrically conductive biocompatible polymer called PEDOT:PSS. This stack is placed on a wafer-thin surface that is subjected to high mechanical tension, which causes the various layers to detach in a highly controlled fashion and fold up origami-style into a nano-biosupercapacitor with a volume 0.001 mm^3, occupying less space than a grain of dust. These tubular biosupercapacitors are therefore 3,000 times smaller than those developed previously, but with a voltage roughly the same as an AAA battery (albeit with far lower actual current flow).

These tiny devices were then placed in saline, blood plasma and blood, where they demonstrated an ability to successfully store energy. The biosupercapacitor proved particularly effective in blood, where it retained up to 70 percent of its capacity after 16 hours of operation. Another reason blood may be a suitable home for the team's biosupercapacitor is that the device works with inherent redox enzymatic reactions and living cells in the solution to supercharge its own charge storage reactions, boosting its performance by 40 percent. The team also subjected the device to the forces it might experience in blood vessels where flow and pressure fluctuate, by placing them in microfluidic channels, kind of like wind-tunnel testing for aerodynamics, where it stood up well. They also used three of the devices chained together to successfully power a tiny pH sensor, which could be placed in the blood vessels to measure pH and detect abnormalities that could be indicative of disease, such as a tumor growth.
The findings have been published in the journal Nature Communications.

Apple Wins Patent For Dual-Display MacBook With Virtual Keyboard, Wireless Charging Capabilities (9to5mac.com) 69

The US Patent and Trademark Office has granted a patent to Apple for a dual-display MacBook with a virtual keyboard replacing the traditional keyboard and with the ability to wirelessly charge an iPhone. 9to5Mac reports: As reported by Patently Apple, this patent was submitted three years ago, and only now has Apple won it. With this patent, the company could take a radical path and get rid of a physical keyboard. The interesting thing about this application is that while rumors suggest that Apple will remove the only touchable interface on the MacBook Pro, the Touch Bar, this patent imagines a MacBook with no physical keyboard at all. Patently Apple says this virtual keyboard could be rearranged, swapping the position of the virtual keyboard and trackpad. With a virtual keyboard, Apple could bring gestures from iOS and iPadOS as well, such as pinch, zoom, slide to select, and more. In the patent, Apple says this MacBook includes biometric sensors, which we could interpret as Face ID, fingerprint sensors (aka Touch ID), and a wireless charger, which would be in the left down corner of the notebook.

Bosch Says the Semiconductor Supply Chains In the Car Industry No Longer Work (cnbc.com) 118

An anonymous reader quotes a report from CNBC, written by Sam Shead: German technology and engineering group Bosch, which is the world's largest car-parts supplier, believes semiconductor supply chains in the automotive industry are no longer fit for purpose as the global chip shortage rages on. Harald Kroeger, a member of the Bosch management board, told CNBC's Annette Weisbach in an exclusive interview Monday that supply chains have buckled in the last year as demand for chips in everything from cars to PlayStation 5s and electric toothbrushes has surged worldwide. Coinciding with the surge in demand, several key semiconductor manufacturing sites were forced to halt production, Kroeger said.

In February, a winter storm in Texas caused blackouts at NXP Semiconductors, which is a major provider of automotive and mobile phone chips. In March, there was a fire at a semiconductor plant in Japan operated by Renesas, one of the car industry's biggest chip suppliers. In August, factories in Malaysia have been abandoned as national lockdowns were introduced to reduce the spread of the coronavirus. Volkswagen and BMW cut their production as they struggled to get the chips they needed to build their cars. These companies and semiconductor suppliers should now be looking to figure out how the chip supply chain can be improved, Kroeger said.

"As a team, we need to sit together and ask, for the future operating system is there a better way to have longer lead times," he said. "I think what we need is more stock on some parts [of the supply chain] because some of those semiconductors need six months to be produced. You cannot run on a system [where] every two weeks you get an order. That doesn't work." Semiconductor supply chain issues have been quietly managed by the automotive in the past but now is a time for change, according to Kroeger, who believes demand is only going to increase with the rise of electric vehicles and autonomous vehicles. "Every car that gets smarter needs more semiconductors," Kroeger said. Electric cars need very powerful and efficient semiconductors in order to to get more range out of each kilowatt hour of battery, he added. Kroeger said he expects the chip shortage to extend "way into 2022" adding that he hopes demand remains stable. "We need to ramp up supplies so we can fulfill that demand," he said.

World's Biggest Wind Turbine Shows the Disproportionate Power of Scale (newatlas.com) 201

China's MingYang Smart Energy has announced an offshore wind turbine even bigger than GE's monstrous Haliade-X. From a report: The MySE 16.0-242 is a 16-megawatt, 242-meter-tall (794-ft) behemoth capable of powering 20,000 homes per unit over a 25-year service life. The stats on these renewable-energy colossi are getting pretty crazy. When MingYang's new turbine first spins up in prototype form next year, its three 118-m (387-ft) blades will sweep a 46,000-sq-m (495,140-sq-ft) area bigger than six soccer fields. Every year, each one expected to generate 80 GWh of electricity. That's 45 percent more than the company's MySE 11.0-203, from just a 19 percent increase in diameter. No wonder these things keep getting bigger; the bigger they get, the better they seem to work, and the fewer expensive installation projects need to be undertaken to develop the same capacity.

45 Teraflops: Intel Unveils Details of Its 100-Billion Transistor AI Chip (siliconangle.com) 16

At its annual Architecture Day semiconductor event Thursday, Intel revealed new details about its powerful Ponte Vecchio chip for data centers, reports SiliconANGLE: Intel is looking to take on Nvidia Corp. in the AI silicon market with Ponte Vecchio, which the company describes as its most complex system-on-chip or SOC to date. Ponte Vecchio features some 100 billion transistors, nearly twice as many as Nvidia's flagship A100 data center graphics processing unit. The chip's 100 billion transistors are divided among no fewer than 47 individual processing modules made using five different manufacturing processes. Normally, an SOC's processing modules are arranged side by side in a flat two-dimensional design. Ponte Vecchio, however, stacks the modules on one another in a vertical, three-dimensional structure created using Intel's Foveros technology.

The bulk of Ponte Vecchio's processing power comes from a set of modules aptly called the Compute Tiles. Each Compute Tile has eight Xe cores, GPU cores specifically optimized to run AI workloads. Every Xe core, in turn, consists of eight vector engines and eight matrix engines, processing modules specifically built to run the narrow set of mathematical operations that AI models use to turn data into insights... Intel shared early performance data about the chip in conjunction with the release of the technical details. According to the company, early Ponte Vecchio silicon has demonstrated performance of more than 45 teraflops, or about 45 trillion operations per second.

The article adds that it achieved those speeds while processing 32-bit single-precision floating-point values floating point values — and that at least one customer has already signed up to use Ponte Vecchio. The Argonne National Laboratory will include Ponte Vecchio chips in its upcoming $500 million Aurora supercomputer. Aurora will provide one exaflop of performance when it becomes fully operational, the equivalent of a quintillion calculations per second.

What Does It Take to Build the World's Largest Computer Chip? (newyorker.com) 23

The New Yorker looks at Cerebras, a startup which has raised nearly half a billion dollars to build massive plate-sized chips targeted at AI applications — the largest computer chip in the world. In the end, said Cerebras's co-founder Andrew Feldman, the mega-chip design offers several advantages. Cores communicate faster when they're on the same chip: instead of being spread around a room, the computer's brain is now in a single skull. Big chips handle memory better, too. Typically, a small chip that's ready to process a file must first fetch it from a shared memory chip located elsewhere on its circuit board; only the most frequently used data might be cached closer to home...

A typical, large computer chip might draw three hundred and fifty watts of power, but Cerebras's giant chip draws fifteen kilowatts — enough to run a small house. "Nobody ever delivered that much power to a chip," Feldman said. "Nobody ever had to cool a chip like that." In the end, three-quarters of the CS-1, the computer that Cerebras built around its WSE-1 chip, is dedicated to preventing the motherboard from melting. Most computers use fans to blow cool air over their processors, but the CS-1 uses water, which conducts heat better; connected to piping and sitting atop the silicon is a water-cooled plate, made of a custom copper alloy that won't expand too much when warmed, and polished to perfection so as not to scratch the chip. On most chips, data and power flow in through wires at the edges, in roughly the same way that they arrive at a suburban house; for the more metropolitan Wafer-Scale Engines, they needed to come in perpendicularly, from below. The engineers had to invent a new connecting material that could withstand the heat and stress of the mega-chip environment. "That took us more than a year," Feldman said...

[I]n a rack in a data center, it takes up the same space as fifteen of the pizza-box-size machines powered by G.P.U.s. Custom-built machine-learning software works to assign tasks to the chip in the most efficient way possible, and even distributes work in order to prevent cold spots, so that the wafer doesn't crack.... According to Cerebras, the CS-1 is being used in several world-class labs — including the Lawrence Livermore National Laboratory, the Pittsburgh Supercomputing Center, and E.P.C.C., the supercomputing centre at the University of Edinburgh — as well as by pharmaceutical companies, industrial firms, and "military and intelligence customers." Earlier this year, in a blog post, an engineer at the pharmaceutical company AstraZeneca wrote that it had used a CS-1 to train a neural network that could extract information from research papers; the computer performed in two days what would take "a large cluster of G.P.U.s" two weeks.

The U.S. National Energy Technology Laboratory reported that its CS-1 solved a system of equations more than two hundred times faster than its supercomputer, while using "a fraction" of the power consumption. "To our knowledge, this is the first ever system capable of faster-than real-time simulation of millions of cells in realistic fluid-dynamics models," the researchers wrote. They concluded that, because of scaling inefficiencies, there could be no version of their supercomputer big enough to beat the CS-1.... Bronis de Supinski, the C.T.O. for Livermore Computing, told me that, in initial tests, the CS-1 had run neural networks about five times as fast per transistor as a cluster of G.P.U.s, and had accelerated network training even more.

It all suggests one possible work-around for Moore's Law: optimizing chips for specific applications. "For now," Feldman tells the New Yorker, "progress will come through specialization."

Hydrogen Lobbyist Quits, Calls 'Blue Hydrogen' a Distraction Possibly Locking in Fossil Fuel Use (arstechnica.com) 189

Remember that study that found that "blue" hydrogen (produced from natural gas using a carbon-capture technique) may be worse for the planet than coal?

"That study was apparently a tipping point for Chris Jackson, who this week stepped down as chair of the UK Hydrogen and Fuel Cell Association..." reports Ars Technica. Jackson wrote in a LinkedIn post announcing his resignation, "while there might not be a single 'right' answer, there are answers that are wrong." Jackson continues by saying that blue hydrogen is "at best an expensive distraction, and at worst a lock-in for continued fossil fuel use" which would derail goals that the country and the world have set for decarbonizing the economy. He takes particular issue with the fact that oil and gas companies have asked the UK government for decades of subsidies while also claiming that blue hydrogen will be inexpensive to produce. "If the false claims made by oil companies about the cost of blue hydrogen were true, their projects would make a profit by 2030," he told The Guardian. "Instead, they're asking taxpayers for billions in subsidies for the next 25 years. They should tell the government they don't need it. The fact that they don't tells you everything you need to know."

Samsung Surpasses Intel to Become Top Semiconductor Manufacturer (tomshardware.com) 19

Tom's Hardware reports: Based on revenue, Samsung Electronics has reclaimed the number one semiconductor manufacturer spot on the back of a strong Q2 2021, according to the latest IC Insight's The McClean Report, which investigates the state of the semiconductor industry in several areas.

The South Korean company achieved a 19 percent increase in overall IC sales compared to Q1 2021, bringing in a total of $20.29 billion in the April-June period alone... On the other hand, Intel achieved a smaller three percent QoQ (Quarter-over-Quarter) increase that resulted in a cool $19.3 billion in chip sales. For reference, AMD, which is generally considered to have a competitive CPU portfolio compared to Intel, brought in a comparatively measly $3.85 billion...

According to the present-day report, Samsung has achieved the top spot mainly due to ascending ASP (Average Sale Price) of NAND and DRAM, with the latter being a significant high-volume advantage over Intel, which doesn't produce RAM. Samsung had last been the top manufacturer back in Q3 2018 — again on the back of strong NAND and DRAM results in the midst of a market shortage.
