The Society of Automotive Engineers, a U.S.-based standards organization known as SAE International, announced plans to support Tesla's EV "North American Charging Standard" or NACS port. "SAE's adoption will make it easier for electric vehicle charging station manufacturers and operators to implement the port while also making charging for EV owners more consistent and reliable," reports The Verge. From the report: Tesla's formerly proprietary charging port was opened up last year in a bid to become the de facto EV standard in the US. The US Joint Office of Energy and Transportation has worked with Tesla and the SAE in an effort to expedite the Tesla plug as a standard to improve the country's charging infrastructure.

SAE is also working with the ChargeX consortium, which was put together by the Biden administration so the Department of Energy's National Labs can help EV manufacturers create consistent tech across vehicles and chargers for items like universal error codes. SAE is lending its Public Key Infrastructure (PKI) technology to make charging more secure against cyber attacks. Also today, ChargePoint announced that customers setting up charging stations with its equipment could add Tesla's port standard to new orders of several commercial AC stations and DC fast chargers, as well as home AC charging systems later this year (via Electrek).

ChargePoint joins a handful of similar electric vehicle charging station companies that have announced support for Tesla's charging port. The standard has been gaining momentum since major legacy automakers Ford, GM, and Rivian all announced commitments to add Tesla's plug to their future vehicles. [...] Now, with SAE supporting NACS, larger EV charging company holdouts like the Volkswagen-owned Electrify America may have an easier time making the jump.

A collection of over 2,200 new old stock computers from the 1980s, manufactured by a company called NABU and featuring a groundbreaking pre-internet network, are being liberated from a barn in Massachusetts. "In a way, this is two stories: The first, of a breakthrough network from Canada, a consumer-friendly 1983 version of the internet decades ahead of its time," writes Ernie Smith via Motherboard. "The other story, of the man who got a hold of these machines, held onto them for 33 years, and mysteriously allowed them to flood the used market one day. One day, thanks to a confluence of the right people noticing the right eBay listings, these two stories merged and created a third story -- the tale of a computer network, brought back to life." An anonymous Slashdot reader shares an excerpt from the report: For more than two decades, the biggest retro computing story in recent memory sat like a sleeper cell in a Massachusetts barn. The barn was in danger of collapse. It could no longer protect the fleet of identical devices hiding inside. A story like this doesn't need the flash of a keynote or a high-profile marketing campaign. It really just needs someone to notice. And the reason anyone did notice was because this barn could no longer support the roughly 2,200 machines that hid on its second floor. These computers, with a weight equivalent to roughly 11 full-size vehicles, were basically new, other than the fact that they had sat unopened and unused for nearly four decades, roughly half that time inside this barn. Every box was "new old stock," essentially a manufactured time capsule, waiting to be found by somebody.

These machines, featuring the label of a forgotten brand built around an idea that was tragically too early to succeed, could have disappeared, anonymously, into the junkyard of history, as so many others like them have. Instead, they ended up on eBay, at a bargain-basement price of $59.99 each. And when the modern retro computing community turned them on, what they found was something worth bringing back to life. It took a while for anyone to notice these stylish metal-and-plastic machines from 1983. First, information spread like whispers in the community of tech forums, Discord servers, and Patreon channels where retro tech collectors hid. But then, a well-known tech YouTuber, Adrian Black, did a video about them, and these eBay machines, slapped with the logo of a company called NABU, were anonymous no more. [...]

Black was impressed. These devices, which utilized the landmark Z80 processor -- a chip common in embedded systems, arcade machines like Pac-Man, and home consoles like the Colecovision -- had an architecture very similar to the widely used MSX platform, making them a great choice for device hackers. (Well, minus the fact that they didn't have floppy drives.) Plus, they were essentially new. "It's new old stock, but it is tested," he says at the beginning of the clip. "I think the seller actually peeled the original tape off, tested it, and then taped it back up again." Essentially, this was the retro-computing version of a unicorn: An extremely obscure platform, being sold at a scale wide enough that basically anyone who wanted one could have it. And on top of all that, NABU -- an acronym standing for Natural Access to Bi-directional Utilities -- was essentially the 1983 version of AOL, except built around proprietary hardware. The flood of interest was so significant that it knocked the seller's eBay account offline for months while the company verified that the units were actually his. (They were.)

For people who love tinkering with devices, there was a lot to work with here, especially in 2023. There was a real chance that this relic of the past could live again, with its network available to anyone who took a chance on buying one of these devices. "The kind of hardware and software hacking that people are doing with those wouldn't have been possible 10 or even 5 years ago," says Sean Malseed, host of the popular YouTube channel Action Retro and one of the many people who bought a NABU from the mysterious eBay listing. "These machines were once considered basically e-waste, but instead they're seeing a very unlikely renaissance." So where did this computer come from? Why did this seller have so many? And why didn't you know about the NABU until now? [...]

Volve has joined Ford, General Motors, and Rivian in adopting Tesla's proprietary charging port. Car and Driver reports: Volvo says that starting in 2025 all of its electric vehicles will be equipped with a North American Charging Standard (NACS) port. This will allow them to charge at Tesla's far-reaching Supercharger network in Canada, Mexico, and the United States. The charging network is currently said to consist of 12,000-plus fast-chargers and is expected to continue to keep growing. "One major inhibitor to more people making the shift to electric driving, a key step in making transportation more sustainable, is access to easy and convenient charging infrastructure," Volvo CEO Jim Rowan said in a press release.

What does this mean for the owners of Volvo models built before the NACS adoption? The company says its current lineup of EVs, which includes the XC40 Recharge, the C40 Recharge, the recently revealed EX30, and the new three-row EX90 SUV that are are currently equipped with CCS-type charge ports, will be able to use an adapter to connect to Tesla's chargers. Volvo says the CCS-to-NACS adapter will be made available in the first half of next year, but what remains to be seen is how much it will cost, if anything. Also worth noting is that the automaker plans to offer a NACS-to-CCS adapter for future 2025 models for owners who wish to replenish their battery using that style charger.

Fossil fuels continue to dominate the global energy market. According to the industry's Statistical Review of World Energy report, global energy demand rose 1% last year, but fossil fuels still accounted for 82% of supply. Reuters reports: The stubborn lead of oil, gas and coal products in covering most energy demand cemented itself in 2022 despite the largest ever increase in renewables capacity at a combined 266 gigawatts, with solar leading wind power growth, the report said. "Despite further strong growth in wind and solar in the power sector, overall global energy-related greenhouse gas emissions increased again," said the president of the UK-based global industry body Energy Institute, Juliet Davenport. "We are still heading in the opposite direction to that required by the Paris Agreement."

The annual report, a benchmark for the industry, was published for the first time by the Energy Institute together with consultancies KPMG and Kearny after they took it over from BP (BP.L), which had authored the report since the 1950s. Scientists say the world needs to cut greenhouse gas emissions by around 43% by 2030 from 2019 levels to have any hope of meeting the international Paris Agreement goal of keeping warming well below 2C above pre-industrial levels. You can view some highlights from the report here.

An ancient Nevada lakebed could become a vast source of the lithium used in electric car batteries, reports the Associated Press. But "NASA says the same site — flat as a tabletop and undisturbed like none other in the Western Hemisphere — is indispensable for calibrating the razor-sharp measurements of hundreds of satellites orbiting overhead." At the space agency's request, the U.S. Bureau of Land Management has agreed to withdraw 36 square miles (92 square kilometers) of the eastern Nevada terrain from its inventory of federal lands open to potential mineral exploration and mining. NASA says the long, flat piece of land above the untapped lithium deposit in Nevada's Railroad Valley has been used for nearly three decades to get measurements just right to keep satellites and their applications functioning properly. "No other location in the United States is suitable for this purpose," the Bureau of Land Management concluded in April after receiving NASA's input on the tract 250 miles (400 kilometers) northeast of Las Vegas...

In Railroad Valley, satellite calculations are critical to gathering information beamed from space with widespread applications from weather forecasting to national security, agricultural outlooks and natural disasters, according to NASA, which said the satellites "provide vital and often time-critical information touching every aspect of life on Earth." That increasingly includes certifying measurements related to climate change. Thus the Nevada desert paradox, critics say. Although lithium is the main ingredient in batteries for electric vehicles key to reducing greenhouse gases, in this case the metal is buried beneath land NASA says must remain undisturbed to certify the accuracy of satellites monitoring Earth's warming atmosphere...

The area's unchanged nature has allowed NASA to establish a long record of images of the undisturbed topography to assist precise measurement of distances using the travel time of radio signals and assure "absolute radiometric calibration" of sensors on board satellites. "Activities that stand to disrupt the surface integrity of Railroad Valley would risk making the site unusable," Jeremy Eggers, a spokesman for NASA's Goddard Space Flight Center in Greenbelt, Maryland, told The Associated Press.
One company with most of the mining rights says the tract's withdrawal will put more than half the site's value out of reach, according to the article.

But the Associated Press got a supportive quote for the move from the satellite imaging company Planet Labs, which has relied on NASA's site to calibrate more than 250 of its satellites since 2016. "As our nation becomes ever more impacted by an evolving and changing environment, it is critical to have reliable and accurate data and imagery of our planet."

"One of the biggest pain points that comes with driving an electric vehicle is the time it takes to charge the battery," writes CNET. "Startup Ample's new technology can give drivers a full charge in about the same time it takes to fill a gas tank." Ample's model runs on the idea that the fastest charge is the one you never have to do. Its next-generation battery-swapping station can replace the battery on an electric vehicle in about five minutes...

Ample currently operates 12 first-generation swapping stations in the San Francisco Bay Area, mainly serving Uber delivery vehicles. The company expects to launch its next-generation station in the US, as well as Japan and Spain, later this year.
Their drive-through stations work with "just about any" kind of electric vehicle (including larger delivery vehicles), according to CNET's video report. Basically the company uses an "interface tray" that locks under the car (where the battery would go) containing its own charged battery cells. When a car drives in, a robotic system simply removes that tray and replaces it with another with fully-charged battery cells.

The company's co-founder argues this makes charging stations more like gas stations which service every kind of car — and adds that it's incredibly easy to deploy. "There's no construction involved... It comes in pre-built parts. You go through, connect them, test them — and you're up and running."

They've already got a deal with American EV automaker Fisker.

Interesting Engineering reports: Chinese authorities have officially given the green light to commission a working thorium-based molten salt nuclear reactor. Currently under construction since 2018, the reactor in question, "Thorium Molten Salt Reactor — Liquid Fuel 1" (TMSR-LF1), is being built at the Hongshagang Industrial Cluster, Wuwei City, Gansu Province.

If successful, the TMSR-LF1 has the potential to open doors for developing and constructing a more extensive demonstration facility by 2030. Additionally, it could lead to constructing a TMSR fuel salt batch pyro-process demonstration facility, which would enable the utilization of the thorium-uranium cycle by the early 2040s...

It runs on a combination of thorium and uranium-235, enriched at 19.75 percent by weight, and can operate at a maximum temperature of 650C for up to 10 years. The liquid fuel design is based on the Molten-Salt Reactor Experiment conducted by Oak Ridge National Laboratory in the 1960s...

China intends to construct a reactor with a capacity of 373 MWt by 2030 if the TMSR-LF1 succeeds.
Thorium is more abundant than uranium, notes the South China Morning Post — and China is thought to have one of the world's largest thorium reserves. But a thorium reactor should also produce less waste, and using molten salts as both a fuel and a coolant "potentially eliminates the need for large quantities of water, which is a significant advantage in areas where water resources are limited."

India has also been pursuing thorium-based nuclear technologies, including MSRs. The Indian Molten Salt Breeder Reactor project, initiated in the 1980s, aimed to develop a thorium-based breeder reactor. However, the project has faced challenges related to materials compatibility, fuel reprocessing and overall system complexity and has not progressed to commercial-scale use...

China reportedly plans to sell small thorium reactors to other countries as part of the Belt and Road Initiative, Beijing's global infrastructure plan.

Today, Rivian announced that it is switching from the Combined Charging System (CCS) standard to the North American Charging Standard (NACS), tesla's competing standard, in 2024. The automaker joins Ford and General Motors in adopting Tesla's charging plugs for its future electric vehicles. Ars Technica reports: "We're excited to work with Tesla and to see collaborations like this help advance the world toward carbon neutrality. The adoption of the North American Charging Standard will enable our existing and future customers to leverage Tesla's expansive Supercharger network while we continue to build out our Rivian Adventure Network. We look forward to continuing to find new ways to accelerate EV adoption," said Rivian founder and CEO RJ Scaringe in a statement.

In an email to customers, Rivian said that it would make adapters available, so people should not wait for the factory to switch over to the NACS port from CCS1. It also says that it will add Tesla charging sites to its mobile and vehicle navigation apps. From 2025, it will start building NACS ports into its vehicles. Like GM, Rivian is in the midst of deploying thousands of DC fast chargers with CCS1 plugs, and like GM, Rivian says that the switch to NACS does not affect those plans. As with Ford and GM, there are no details as to the terms of the deal between Rivian and Tesla.

The Texas power grid operator, ERCOT, has urged residents and businesses to conserve electricity as the first heat wave of the summer increases air conditioner usage, causing power reserves to potentially fall short. Power prices in the state's day-ahead market reached over $2,500 per MWh, and ERCOT issued a warning about a projected reserve capacity shortage, although controlled outages are not currently necessary. Reuters reports: ERCOT operates the grid for more than 26 million customers representing about 90% of the state's power load. The grid operator issued a "Watch" for what it called a "projected reserve capacity shortage with no market solution available for Tuesday" from 3 p.m. to 9 p.m. local time, which could push ERCOT to take more actions to maintain reliability. Although controlled outages are one of the most extreme actions a grid operator could take to maintain reliability, ERCOT said "controlled outages are not needed at this time."

ERCOT forecast power use would reach 81,348 megawatts (MW) on Tuesday before slipping to 80,991 MW on Wednesday. Tuesday's high, which is a little below a forecast earlier in the day, would still top the grid's current record peak of 80,148 MW on July 20, 2022. Day-ahead power prices for Tuesday settled around $2,500 per MWh at 5 p.m. local time in several zones, including Houston and Dallas, according to the ERCOT website. That compares with next-day prices at the ERCOT North Hub , which includes Dallas, that traded for $37 per MWh for the peak hours during the day on Monday, the U.S. Juneteenth holiday.

Apple today announced that its self-service repair program will be expanding to the iPhone 14 lineup, 13-inch MacBook Air with the M2 chip, and 14-inch and 16-inch MacBook Pro models with M2 Pro and M2 Max chips starting June 21. From a report: First launched in April 2022, Apple's program provides customers with access to parts, manuals, and tools to repair select devices. Apple says the program is designed for anyone with "experience repairing electronic devices," but says the "vast majority" of customers are better off visiting an Apple Store or Apple Authorized Service Provider. Apple also announced that customers can now complete the post-repair System Configuration process by placing the device into Diagnostics Mode and following the on-screen prompts. Users no longer need to contact the program's support team to complete this step, which verifies that the parts are genuine and working properly.

According to an industry insider, LCD TVs won't see any further development because all new R&D money is being spent on self-emissive displays like MicroLED and OLED, as well as on backlight technology like Mini-LED. Tom's Guide reports: According to Bob Raikes from Display Daily, it's all about OLED development. "I asked EMD (which is the US name of Merck KGaA and is by far the dominant supplier of LC materials), what they were doing to push LC materials for displays onto the next stage ... They are developing LCs for privacy windows and antennas, but they told us that 'there is no pull from clients' for significant development in LC materials," Raikes wrote in a recent article. "That shouldn't have been a surprise to me -- I have been talking about the switch to OLED and other emissive displays for the premium end (and later the mainstream) of the display market for a lot of years. Still, after decades of reporting on LC developments, it took a moment to sink in!"

As for what, specifically, manufacturers are working on, it's the production of QD-OLED panels for use in the high-end Samsung and Sony TVs like the Samsung S95C OLED and Sony A95K OLED as well as the development of PHOLED panels that use a blue phosphorescent material that has a longer shelf life and can go brighter than the traditional organic material in OLED panels. [...] Sadly, LCD TVs' days are coming to a close, but OLED TVs are still going strong.

As part of a series of articles on smart homes, the Verge visits an energy-efficient home in the southern California desert that's "part of California's first planned smart, solar-powered residential microgrid community." A surprisingly small number of solar panels on the roof soak up the sun in the desert landscape... funneling power into the tightly designed building envelope. Here, a 13-kilowatt hour home battery sits beside a smart load panel that controls every electrical appliance in the home, from the hybrid electric heat-pump water heater and high-efficiency heat pump HVAC system — both Wi-Fi enabled to share data — to the light switches, EnergyStar fridge, and energy-efficient induction cooktop. Using software algorithms, the Schneider load center intelligently determines where to best draw power from — the SunPower solar panels, the battery, or the grid. It then makes recommendations the Conriques can use to set automations that change power sources or reduce energy use when prices and demand spike...

The 43 new residences in KB Home-built Shadow Mountain, which launched in November 2022, and the 176 more planned as part of two communities, Durango and Oak Shade, are all-electric, solar-powered smart homes. By next year they will be connected to a 2.3 megawatt-hour community battery, sending any excess energy their panels generate to the common power source and creating a community microgrid. When the power goes down, the microgrid will kick in, isolating all 219 homes from the grid and keeping their essential functions up and running. The homes will draw first from their own battery (and potentially their EV) and then from the community battery. "When the system hits a potential steady state, they can ride a power outage for days, if not in perpetuity, with proper solar production," explains Brad Wills of Schneider Electric, manufacturers of the home's smart load panel, the community's microgrid components, and the software that runs the system...

Developed as a partnership between SunPower, KB Home, University of California, Irvine, Schneider Electric, Southern California Edison, Kia America, and the US Department of Energy, Shadow Mountain is designed to be a blueprint for how we can build better, smarter communities in the future... A recent DOE study estimated that by 2030, grid-interactive efficient buildings like those at Shadow Mountain could save up to $18 billion per year in power system costs and cut 80 million tons of carbon emissions annually.
The article describes how the community helps the larger power grid:

• They can send electricity back into the grid during periods of peak demand.

• The local power company now also has the option to "island" the entire community off the grid in times of high demand.

• The community "is also trialing high-output vehicle-to-home and vehicle-to-grid functions."

The Ecoomist asks: How can we "green" the high-temperature chemical processes in industries like steelmaking or the production of chemical or cement. "Because it is tricky or impossible to produce such temperatures for some industrial processes using electricity alone, firms rely on fossil fuels."

But a Finnish engineering firm called Coolbrook thinks they have an answer: The easiest way to think about Coolbrook's system is as a gas turbine in reverse. A conventional gas turbine — as used in power stations or jet engines — burns fossil fuel to create a hot, high-pressure gas that spins rotor blades. That rotational energy can be used to run a thrust-generating fan (as in jet aircraft) or converted to electricity in a generator (as in a power station). The new system begins instead with an electric motor. The motor spins the turbine's rotors. Gas or liquid is then fed to the turbine. Once inside, the rotors accelerate the stuff to supersonic speeds, and then rapidly slow it again. The sudden deceleration transforms the kinetic energy contained in the accelerated gas or fluid into heat. If the motor is powered by green electricity, then no carbon dioxide is produced...

Laboratory trials have shown that yields from the electrified process could be significantly higher than what can be obtained with fossil fuels. Assuming that everything goes according to plan, the firm will try producing heat for several other industrial processes... Joonas Rauramo, Coolbrook's boss, reckons his firm's technology could eliminate perhaps 30% of heavy-industrial emissions. And, he says, it can do so without needing to invent anything fundamentally new. "It is a known science," says Mr Rauramo. "It has just not been applied in exactly the way we are doing it."
The article's subheading puts it succinctly. "Running a turbine backwards can produce green heat."

"I predict that Generative Artificial Intelligence is going to go a long way toward keeping Moore's Law in force," writes long-time tech pundit Robert X. Cringely, "and the way this is going to happen says a lot about the chip business, global economics, and Artificial Intelligence, itself." The current el cheapo AI research frenzy is likely to subside as LLaMA ages into obsolescence and has to be replaced by something more expensive, putting Google, Microsoft and OpenAI back in control. Understand, too, that these big, established companies like the idea of LLMs costing so much to build because that makes it harder for startups to disrupt. It's a form of restraint of trade, though not illegal...

[T]here is an opportunity for vertical LLMs trained on different data — real data from industries like medicine and auto mechanics. Whoever owns this data will own these markets. What will make these models both better and cheaper is they can be built from a LLaMA base because most of that data doesn't have to change over time... Bloomberg has already done this for investment advice using its unique database of historical financial information. With an average of 50 billion nodes, these vertical models will cost only five percent as much to run as OpenAI's one billion node GPT-4...

[I]t ought to be pretty simple to apply AI to chip design, building custom chip design models to iterate into existing simulators and refine new designs that actually have a pretty good chance of being novel.

And who will be the first to leverage this chip AI? China... Look for fabless AI chip startups to spring-up around Chinese universities and for the Chinese Communist Party to put lots of money into this very cost-effective work. Because even if it's used just to slim-down and improve existing designs, that's another generation of chips China might otherwise not have had at all.

Quanta magazine thinks there's a better alternative to the artificial neural networks (or ANNs) powering AI systems. (Alternate URL) For one, ANNs are "super power-hungry," said Cornelia Fermüller, a computer scientist at the University of Maryland. "And the other issue is [their] lack of transparency." Such systems are so complicated that no one truly understands what they're doing, or why they work so well. This, in turn, makes it almost impossible to get them to reason by analogy, which is what humans do — using symbols for objects, ideas and the relationships between them....

Bruno Olshausen, a neuroscientist at the University of California, Berkeley, and others argue that information in the brain is represented by the activity of numerous neurons... This is the starting point for a radically different approach to computation known as hyperdimensional computing. The key is that each piece of information, such as the notion of a car, or its make, model or color, or all of it together, is represented as a single entity: a hyperdimensional vector. A vector is simply an ordered array of numbers. A 3D vector, for example, comprises three numbers: the x, y and z coordinates of a point in 3D space. A hyperdimensional vector, or hypervector, could be an array of 10,000 numbers, say, representing a point in 10,000-dimensional space. These mathematical objects and the algebra to manipulate them are flexible and powerful enough to take modern computing beyond some of its current limitations and foster a new approach to artificial intelligence...

Hyperdimensional computing tolerates errors better, because even if a hypervector suffers significant numbers of random bit flips, it is still close to the original vector. This implies that any reasoning using these vectors is not meaningfully impacted in the face of errors. The team of Xun Jiao, a computer scientist at Villanova University, has shown that these systems are at least 10 times more tolerant of hardware faults than traditional ANNs, which themselves are orders of magnitude more resilient than traditional computing architectures...

All of these benefits over traditional computing suggest that hyperdimensional computing is well suited for a new generation of extremely sturdy, low-power hardware. It's also compatible with "in-memory computing systems," which perform the computing on the same hardware that stores data (unlike existing von Neumann computers that inefficiently shuttle data between memory and the central processing unit). Some of these new devices can be analog, operating at very low voltages, making them energy-efficient but also prone to random noise.

"If everyone has an electric car, will the electric grid be able to support all those cars being recharged?"

That's the question being answered this week in the Washington Post's "Climate Coach" newsletter: We can already see a preview of our electric future in Norway, one of the countries with the highest share of EVs. More than 90 percent of new cars sold in the country were plug-in electric, according to the latest data, from May. More than 20 percent of the country's overall vehicle fleet is electric, a share expected to rise to one-third by 2025. So far, the grid has essentially shrugged it off. "We haven't seen any issue of the grid collapsing," says Anne Nysæther, a managing director at Elvia, a utility serving Oslo and the surrounding areas with the nation's largest concentration of EVs. The country, now almost entirely powered by renewables, has easily met the extra demand from EVs while slashing greenhouse gas emissions. That's good, because Norway will ban all new petrol and diesel cars by 2025...

To electrify everything — all these expected EVs, heat pumps and other big power draws — [the U.S.] will need to start building up our grid, according to Jesse Jenkins, an energy modeling and engineering expert at Princeton University. The United States must at least double its electricity supply by 2050, while stringing up 75,000 miles of new high-voltage lines by 2035, the equivalent of 15 round trips from Los Angeles to New York City, and connect new wind and solar generation to the grid. That sounds like a lot. But something like this has already been done. From the 1970s to the 1990s, the U.S. built new transmission capacity at a speed close to what is required today, writes Jenkins in Mother Jones, even as electricity demand grew.

An anonymous reader shared this report from CNN: Over the past few years, restaurants from White Castle to Wendy's have been investing in artificial intelligence tech for drive-thrus... [E]fforts have ramped up recently, with two announcements in May. CKE Restaurants (owner of Hardee's and Carl's Jr.) said it will roll out AI ordering capability more broadly after a successful pilot. Soon after, Wendy's said it had expanded its partnership with Google Cloud to include an AI ordering tool at the drive-thru. The chain is piloting the program in Columbus, Ohio this month.
Fast food restaurants "say it's a way to ease the burden placed on overworked employees, and a solution to bogged down drive-thrus overwhelmed by a surge of customers," according to the article. "But customers — and workers — may not be thrilled with the technology... " Frustrated customers have already documented cases of AI getting their orders wrong, and experts warn the noisy drive-thru is a challenging environment for the technology. And AI may swipe hours or even entire jobs away from fast-food workers... Out of ten orders placed by customers at an Indiana White Castle that uses AI in its drive-thru, three people asked to speak with a human employee, because of either an error or a desire to simply talk to a person, the Wall Street Journal recently reported.

That said, AI inherently improves as it collects more data. The experience may improve after tools take more orders and learn to better recognize voices.

For companies, a hiccup-y start seems to be well worth the potential boost to sales. One of the main benefits of using AI in the drive-thru is that it upsells relentlessly — leading customers to spend more, according to Presto Automation, an AI company that works with restaurants and has partnered with CKE... Some analysts are similarly bullish. "We believe that AI voice recognition and digital only lanes could speed up the average drive through service time by at least 20-30%," analysts wrote in a Bernstein Research note published in March. "We expect AI to augment the competitive advantages of restaurants with digital culture."

Short-staffed restaurants may see AI as a way to fill in the gaps... Some restaurants are still struggling to find staff. Meanwhile, dining trends have changed. The pandemic sent customers to drive-thrus in droves and some have kept the habit, contributing to slower drive-thru times.

The new Mac Studio started shipping to customers this week, giving product reviewers a chance to test Apple's "most capable chip ever." According to new benchmarks by YouTuber Luke Miani, the M2 Ultra features nearly double the GPU performance of last year's M1 Ultra, with notable performance improvements in other areas. 9to5Mac reports: While the M1 Max and M1 Ultra are blazing fast, the difference between the two wasn't as notable as some expected. In many tasks, the much cheaper M1 Max wasn't too far off from the top-end M1 Ultra variant, especially in video editing, photo editing, and 3D rendering. Despite the M1 Ultra literally being 2 M1 Max's fused, the performance was never doubled. For the M2 series, Apple has made some significant changes under the hood, especially in GPU scaling. In Luke's testing, he found that in some GPU heavy applications, like Blender 3D and 3DMark, the M2 Ultra was sometimes precisely twice the performance of M2 Max -- perfect GPU scaling! In Final Cut Pro exports, it nearly doubled again. He also found that the M2 Ultra doubled the GPU performance of the M1 Ultra in these same benchmarks -- a genuinely remarkable year-over-year upgrade.

The reason for the massive performance improvement is that Apple added a memory controller chip to the M2 generation that balances the load between all of M2 Ultra's cores -- M1 Ultra required the ram to be maxed out before using all cores. M1 Ultra was very good at doing many tasks simultaneously but struggled to do one task, such as benchmarking or rendering, faster than the M1 Max. With M2 Ultra, because of this new memory controller, Apple can now achieve the same incredible performance without the memory buffer needing to be maxed out. It's important to note that some applications cannot take advantage of the M2 Ultra fully, and in non-optimized applications, you should not expect double the performance.

Despite this incredible efficiency and performance, the better deal might be the M2 Max. In Luke's testing, the M2 Max performed very similarly or outperformed last year's M1 Ultra. In Blender, Final Cut Pro, 3DMark, and Rise of the Tomb Raider, the M2 Max consistently performed the same or better than the M1 Ultra. Instead of finding an M1 Ultra on eBay, it might be best to save money and get the M2 Max if you're planning on doing tasks that heavily utilize the GPU. While the GPU performance is similar, the M1 Ultra still has the advantage of far more CPU cores, and will outperform the M2 Max in CPU heavy workloads.

An anonymous reader quotes a report from Ars Technica: Intel does a lot of things, but it's mostly noted for making and shipping a lot of processors, many of which have been named after bodies of water. So, saying that the company is set to start sending out a processor called Tunnel Falls would seem unsurprising if it weren't for some key details. Among them: The processor's functional units are qubits, and you shouldn't expect to be able to pick one up on New Egg. Ever. Tunnel Falls appears to be named after a waterfall near Intel's Oregon facility, where the company's quantum research team does much of its work. It's a 12-qubit chip, which places it well behind the qubit count of many of Intel's competitors -- all of which are making processors available via cloud services. But Jim Clarke, who heads Intel's quantum efforts, said these differences were due to the company's distinct approach to developing quantum computers.

Intel, in contrast, is attempting to build silicon-based qubits that can benefit from the developments that most of the rest of the company is working on. The company hopes to "ride the coattails of what the CMOS industry has been doing for years," Clarke said in a call with the press and analysts. The goal, according to Clarke, is to make sure the answer to "what do we have to change from our silicon chip in order to make it?" is "as little as possible." The qubits are based on quantum dots, structures that are smaller than the wavelength of an electron in the material. Quantum dots can be used to trap individual electrons, and the properties of the electron can then be addressed to store quantum information. Intel uses its fabrication expertise to craft the quantum dot and create all the neighboring features needed to set and read its state and perform manipulations.

However, Clarke said there are different ways of encoding a qubit in a quantum dot (Loss-DiVincenzo, singlet-triplet, and exchange-only, for those curious). This gets at another key difference with Intel's efforts: While most of its competitors are focused solely on fostering a software developer community, Intel is simultaneously trying to develop a community that will help it improve its hardware. (For software developers, the company also released a software developer kit.) To help get this community going, Intel will send Tunnel Falls processors out to a few universities: The Universities of Maryland, Rochester, Wisconsin, and Sandia National Lab will be the first to receive the new chip, and the company is interested in signing up others. The hope is that researchers at these sites will help Intel characterize sources of error and which forms of qubits provide the best performance. "Overall, Intel has made a daring choice for its quantum strategy," concludes Ars' John Timmer. "Electron-based qubits have been more difficult to work with than many other technologies because they tend to have shorter life spans before they decohere and lose the information they should be holding. Intel is counting on rapid iteration, a large manufacturing capacity, and a large community to help it figure out how to overcome this. But testing quantum computing chips and understanding why their qubits sometimes go wrong is not an easy process; it requires highly specialized refrigeration hardware that takes roughly a day to get the chips down to a temperature where they can be used."

"The company seems to be doing what it needs to overcome that bottleneck, but it's likely to need more than three universities to sign up if the strategy is going to work."

An anonymous reader quotes a report from Scientific American: It could be a new world record, although no one involved wants to talk about it. In the south of France, a collaboration among 35 countries has been birthing one of the largest and most ambitious scientific experiments ever conceived: the giant fusion power machine known as the International Thermonuclear Experimental Reactor (ITER). But the only record ITER seems certain to set doesn't involve "burning" plasma at temperatures 10 times higher than that of the sun's core, keeping this "artificial star" ablaze and generating net energy for seconds at a time or any of fusion energy's other spectacular and myriad prerequisites. Instead ITER is on the verge of a record-setting disaster as accumulated schedule slips and budget overruns threaten to make it the most delayed -- and most cost-inflated -- science project in history.

The ITER project formally began in 2006, when its international partners agreed to fund an estimated [$6.3 billion], 10-year plan that would have seen ITER come online in 2016. The most recent official cost estimate stands at more than [$22 billion], with ITER nominally turning on scarcely two years from now. Documents recently obtained via a lawsuit, however, imply that these figures are woefully outdated: ITER is not just facing several years' worth of additional delays but also a growing internal recognition that the project's remaining technical challenges are poised to send budgets spiraling even further out of control and successful operation ever further into the future.

The documents, drafted a year ago for a private meeting of the ITER Council, ITER's governing body, show that at the time, the project was bracing for a three-year delay -- a doubling of internal estimates prepared just six months earlier. And in the year since those documents were written, the already grim news out of ITER has unfortunately only gotten worse. Yet no one within the ITER Organization has been able to provide estimates of the additional delays, much less the extra expenses expected to result from them. Nor has anyone at the U.S. Department of Energy, which is in charge of the nation's contributions to ITER, been able to do so. When contacted for this story, DOE officials did not respond to any questions by the time of publication.
