An anonymous reader quotes a report from Wired: A new network of 3D-printed gun advocates is growing in America -- and this time things are different. Unlike previous attempts to popularize 3D-printed guns, this operation is entirely decentralized. There's no headquarters, no trademarks, and no real leader. The people behind it reckon that this means they can't be stopped by governments. Known only by his online moniker, Ivan the Troll is the de facto spokesman of an underground wave of 3D-printing gunsmiths. Ivan says he knows of at least 100 people who are actively developing 3D-printed gun technology, and he claims there are thousands taking part in the network. This loose-knit community spans across the whole world.

They communicate across several digital platforms, including Signal, Twitter, IRC, and Discord. They critique each other's work, exchange 3D gun CAD files, offer advice, talk theory, and collaborate on future blueprints. These 3D-printed gun enthusiasts -- who share similar ideas and political viewpoints on gun control -- mostly found each other online via gun control subreddits and forums. Ivan is just one small part of this network. He says he is from Illinois, and is of "college age," but otherwise he remains mostly anonymous, to lie low. At the same time though, he's launched bombastic PR videos demonstrating the new 3D-printed gun parts he's created in his garage, including a Glock 17 handgun frame. Ivan's group says the legal challenges around Defence Distributed and the company's founder Cody Wilson are irrelevant. According to the report, the group is uploading their files individually on services such as Spee.ch, a media-hosting site underpinned by the LBRY blockchain, "and they aren't waiting for anyone to give them permission." It adds: "They've made their own 3D-printed gun designs, modified old ones, and are keeping all the Defence Distributed ones available for free too."

An anonymous reader quotes a report from Engadget: A UN chief is concerned that a Cold War-era nuclear 'coffin' could be leaking radioactive material into the Pacific. According to Phys.org, the structure in question is on Enewetak atoll in the Marshall Islands -- where the U.S. conducted 67 nuclear weapons tests between 1946 and 1958. The tests included the Castle Bravo hydrogen bomb, which was reportedly about 1,000 times bigger than the atomic bomb dropped on Hiroshima. In the late 70s, waste from those tests was dumped into a crater and capped with a concrete dome 18 inches thick. That was intended to be a temporary solution, so the bottom of the crater was never lined.

Now, UN Secretary General Antonio Guterres and Marshall Islands President Hilda Heine fear nuclear waste could be leaking from the pit. They're also concerned about cracks in the concrete, which they worry could break apart if hit by a tropical cyclone. Guterres says the Pacific's nuclear history needs to be addressed.

Google just unveiled its newest version of Glass. It's not made to be a widespread consumer product, but there are business users who will care. And the latest Glass Enterprise Edition 2, with key upgraded specs, shows where most smartglasses are at. From a report: You might remember Glass as a strange 2013 footnote, but Glass has stuck around: it became an enterprise-targeted device in 2017, and has been used in a variety of other assistive ways. Plenty of other AR headsets have been moving into the enterprise space over the last couple of years too, from Microsoft HoloLens 2 to Vuzix' glasses. While the single-display design of Glass isn't going to allow 3D augmented reality like what you'd experience on HoloLens 2, there could be applications for other types of useful augmented reality via the improved built-in camera and upgraded onboard processor. Google's announcement touts the new onboard Qualcomm XR1 chip as enabling "support for computer vision and advanced machine learning capabilities."

Google representatives refused to comment on whether that means the new Glass could possibly adopt some Google Lens-like features, and Google's VP of VR and AR, Clay Bavor, said in a statement that "Using technologies like computer vision and AR, our team's focus has been on building helpful experiences that provide useful information in context. Glass Enterprise Edition 2 does just that, and we're excited to give businesses and their employees tools to help them work better, smarter and faster."

Friday the Washington Post published an essay by Gregory Jaczko, who served on America's Nuclear Regulatory Commission from 2005 to 2009 and was its chairman from 2009 to 2012. He says he'd believed nuclear power was worth the reduction they produced in greenhouse emissions -- until Japan's 2011 nuclear meltdown at the Fukushima power plant.

"Despite working in the industry for more than a decade, I now believe that nuclear power's benefits are no longer enough to risk the welfare of people living near these plants..." [Non-paywalled version here] The current and potential costs -- personal and economic -- are just too high.... The technology and the safety needs are just too complex and demanding to translate into a facility that is simple to design and build. No matter your views on nuclear power in principle, no one can afford to pay this much for two electricity plants. New nuclear is simply off the table in the United States....

Fewer than 10 of Japan's 50 reactors have resumed operations, yet the country's carbon emissions have dropped below their levels before the accident. How? Japan has made significant gains in energy efficiency and solar power.... What about the United States? Nuclear accounts for about 19 percent of U.S. electricity production and most of our carbon-free electricity. Could reactors be phased out here without increasing carbon emissions? If it were completely up to the free market, the answer would be yes, because nuclear is more expensive than almost any other source of electricity today. Renewables such as solar, wind and hydroelectric power generate electricity for less than the nuclear plants under construction in Georgia, and in most places, they produce cheaper electricity than existing nuclear plants that have paid off all their construction costs...

This tech is no longer a viable strategy for dealing with climate change, nor is it a competitive source of power. It is hazardous, expensive and unreliable, and abandoning it wouldn't bring on climate doom. The real choice now is between saving the planet or saving the dying nuclear industry. I vote for the planet.

CNBC reports: Tesla shares fell almost 8% on Friday to their lowest close since December 2016, after the National Transportation Safety Board said the company's Autopilot driver assistance system was engaged during a fatal crash in March... The accident was at least the third of its kind in the U.S. and raises concerns about Tesla's Autopilot technology.
Thursday Elon Musk also told Tesla's employees that he and their CFO will now personally review all expenses going forward in a new "hardcore" attempt to control expenses, calling it "the only way for Tesla to become financially sustainable and succeed in our goal of helping make the world environmentally sustainable."

And then there's the fires, reports CNBC: Recent reports of Tesla vehicles spontaneously catching fire could make potential customers wary at a time when virtually every automaker is getting ready to roll out battery-based vehicles, industry executives and analysts worry... Three of Tesla's sedans went up in flames without warning in recent months, one in Shanghai, another in Hong Kong, a third in San Francisco. Tesla has experienced at least 14 known battery fires in recent years...

Of the 14 known fires involving Tesla vehicles, the majority occurred after a collision, but there have been a growing number of blazes in which its products appear to spontaneously ignite. That appeared to be the case when, on April 21, a security camera in a Shanghai garage captured images of a Model S sedan smoldering before suddenly bursting into flames. Another fire engulfed a Tesla sedan that appears to have been hooked up to one of the company's Superchargers in Hong Kong. Then, two weeks ago, firefighters in San Francisco tweeted that they had been called to a garage where another Tesla Model S was on fire.

In an initial response, the automaker said it did not think the sedan itself was responsible for the California blaze. But it is investigating the two Chinese incidents, it said in a statement, and "out of an abundance of caution, we are revising charge and thermal management settings on Model S and Model X vehicles via an over-the-air software update that will begin rolling out today, to help further protect the battery and improve battery longevity..."
"As the face of the emerging battery-car market, Tesla's troubles have been widely reported, but it is by no means the only manufacturer to have experienced unexpected fires..." reports CNBC.

"Fires have been reported with Chevrolet Volts, Fisker Karmas, Mitsubishi iMiEVs and other electric vehicles."

Fast Company's technology editor Harry McCracken is also Slashdot reader #1,641,347. He contacted us Thursday with a story about Radio Shack's Model 100 -- and a rare training film from 36 years ago: Radio Shack's Model 100 wasn't the first laptop -- but it was the first popular one, and an innovative machine on multiple fronts. It was also the last computer to ship with Microsoft software personally coded by Bill Gates.

I recently came across an internal training film intended to help Radio Shack staffers explain the Model 100's benefits to potential customers. I've shared it -- and some thoughts on the system's importance -- over at Fast Company.
The article calls it "an even more important computer than it generally gets credit for," noting portable computers at the time weighed a whopping 24 pounds -- and required a wall outlet to run. So a four-pound PC that ran off batteries and could fit in a briefcase "introduced people to mind-bending ideas such as using a PC on an airplane" -- even if it only had 8K of memory.

The bankruptcy of one of America's largest coal producers revealed that the company was helping to fund "think tanks that have attacked the link between the burning of fossil fuels and climate change, as well as to several conservative advocacy groups that have attempted to undermine policies intended to shift the economy toward renewable energy," reports the Intercept. The document shows that Cloud Peak Energy helped fund the Institute of Energy Research, a Washington, D.C.-based group that has dismissed the "so-called scientific consensus" on climate change and regularly criticizes investments in renewable energy as a "waste" of resources. Several of the groups that receive funding from Cloud Peak Energy have used aggressive tactics to attempt to discredit environmentalists.

The Center for Consumer Freedom, one of the groups listed in the coal company's filing, is part of a sprawling network of front groups set up by a lobbyist named Rick Berman geared toward attacking green groups such as the Sierra Club and Food & Water Watch as dangerous radicals. Other organizations quietly bankrolled by Cloud Peak Energy have directly shaped state policy... The Montana Policy Institute -- a local libertarian think tank that promotes a discredited claim that world temperatures are falling, not rising, and questions whether humans cause climate change -- also received funding from the firm....

Four years ago, falling coal prices led to a series of bankruptcies of the largest coal companies in America. The filings, first reported by The Intercept, similarly revealed that the coal industry had financed a range of activists and organizations dedicated to spreading doubt about the science underpinning climate change...

In 2016, Greg Zimmerman, an environmental activist, stumbled upon a presentation titled "Survival Is Victory: Lessons From the Tobacco Wars." The slide deck was the creation of Richard Reavey, a vice president for government and public affairs at Cloud Peak Energy, and a former executive at Phillip Morris. Reavey argued that fossil fuel firms, particularly coal, should emulate the tactics of big tobacco, which similarly spent decades battling scientists and regulators over claims that its product harmed public health. In the New York Times coverage of the episode, Reavey told the paper that his firm "has never fought climate change -- never fought it, never denied it or funded anyone who does." The bankruptcy filing from last week, however, suggests otherwise.

dryriver writes: For capitalism to work for consumers in a beneficial way, the big players have to compete hard against each other and innovate courageously. What appears to be happening instead, however, is that every year almost everybody is making roughly the same product at roughly the same price point. Most 4K TVs at the same price point have the same features -- there is little to distinguish manufacturer A from manufacturer B. Ditto for smartphones -- nobody suddenly puts a 3D scanning capable lightfield camera, shake-the-phone-to-charge-it or something similarly innovative into their next phone. Ditto for game consoles -- Xbox and Playstation are not very different from each other at all. Nintendo does "different," but underpowers its hardware. Ditto for laptops -- the only major difference I see in laptops is the quality of the screen panel used and of the cooling system. The last laptop with an auto stereoscopic 3D screen I have seen is the long-discontinued Toshiba Satellite 3D. Ditto for CPUs and GPUs -- it doesn't really matter whether you buy Intel, AMD, or Nvidia. There is nothing so "different" or "distinct" in any of the electronics they make that it makes you go "wow, that is truly groundbreaking." Ditto for sports action cameras, DSLRs, portable storage and just about everything else "tech." So where precisely -- besides pricing and build-quality differences -- is the competition in what these companies are doing? Shouldn't somebody be trying to "pull far ahead of the pack" or "ahead of the curve" with some crazy new feature that nobody else has? Or is true innovation in tech simply dead now?

MySpace, which recently lost 50 million files uploaded between 2003 and 2015, is not alone in encountering problems. As the internet grows, batches of old information are increasingly disappearing from it. From a story: Amazon cloud services, for example, also experienced a substantial outage in 2011 and another in 2017. Though temporary, and without actual loss of data, these outages left users without access to precious and important files for some time. Preserving content or intellectual property on the internet presents a conundrum. If it's accessible, then it isn't safe; if it's safe, then it isn't accessible. Accessible content is subject to tampering, theft or other sorts of bad actions. Only content that is inaccessible can be locked and protected from hacking.

The internet currently accesses about 15 zettabytes of data, and is growing at a rate of 70 terabytes per second. It is an admittedly leaky vessel, and content is constantly going offline to wind up lost forever. Massive and desperate efforts are underway to preserve whatever is worth preserving, but even sorting out what is and what is not is itself a formidable undertaking. What will be of value in 10 years -- or 50 years? And how to preserve it? Acid-free paper can last 500 years; stone inscriptions even longer. But magnetic media like hard drives have a much shorter life, lasting only three to five years. They also need to be copied and verified on a very short life cycle to avoid data degradation at observed failure rates between 3% and 8% annually. Then there is also a problem of software preservation: How can people today or in the future interpret those WordPerfect or WordStar files from the 1980s, when the original software companies have stopped supporting them or gone out of business?

An anonymous reader quotes a report from The Guardian: A mind-controlled hearing aid that allows the wearer to focus on particular voices has been created by scientists, who say it could transform the ability of those with hearing impairments to cope with noisy environments. The device mimics the brain's natural ability to single out and amplify one voice against background conversation. Until now, even the most advanced hearing aids work by boosting all voices at once, which can be experienced as a cacophony of sound for the wearer, especially in crowded environments.

The hearing aid first uses an algorithm to automatically separate the voices of multiple speakers. It then compares these audio tracks to the brain activity of the listener. Previous work found that it is possible to identify which person someone is paying attention to, as their brain activity tracks the sound waves of that voice most closely. The device compares the audio of each speaker to the brain waves of the person wearing the hearing aid. The speaker whose voice pattern most closely matches the listener's brain waves is amplified over the others, allowing them to effortlessly tune in to that person. The scientists developed an earlier version of the system in 2017 that, while promising, had the major limitation that it had to be pre-trained to recognize speakers' voices. Crucially, the latest device works for voices it has never heard before. The study has been published in the journal Science Advances.

Valve's Steam Link app, which brings streaming games to your mobile device, is now available as a free download for iOS and Apple TV. The iOS launch comes nearly one year after Apple rejected the app due to "business conflicts." GameSpot reports: The Steam Link app promises to bring "desktop gaming to your iPhone or iPad." Users can pair a Steam controller or any MFI (Made-for-iPhone/iPad) controller to play games over a network connection provided they are on the same local network. The Steam Link app is effectively a replacement for the physical Steam Link device that Steam discontinued in 2018. Steam Link is already available on Android. As the Verge notes in their report, the biggest difference between the iOS and Android versions is that the iOS Steam Link app "doesn't allow users to purchase games from the Steam store, unlike on Android."

You can download Steam Link from iTunes here.

Most of the solar cells Tesla is producing at its Gigafactory in upstate New York "are being sold overseas instead of being used in the company's trademark 'Solar Roof' as originally intended," reports Reuters. "The exporting underscores the depth of Tesla's troubles in the U.S. solar business, which the electric car maker entered in 2016 with its controversial $2.6 billion purchase of SolarCity." From the report: Tesla has only sporadically purchased solar cells produced by its partner in the factory, Panasonic Corp, according to a Buffalo solar factory employee speaking on condition of anonymity. The rest are going largely to foreign buyers, according to a Panasonic letter to U.S. Customs officials reviewed by Reuters. When the two firms announced the partnership in 2016, the companies said they would collaborate on cell and module production and Tesla would make a long-term commitment to buy the cells from Panasonic. Cells are components that convert the sun's light into electricity; they are combined to make solar panels.

The situation raises new questions about the viability of cash-strapped Tesla's solar business. Musk once called the deal a "no brainer" - but some investors panned it as a bailout of an affiliated firm at the expense of Tesla shareholders. Before the merger, Musk had served as chairman of SolarCity's board of directors, and his cousin, Lyndon Rive, was the company's CEO. [...] Panasonic also produces traditional solar panels at the Buffalo plant for Tesla, but has been selling many of them to other buyers since at least last year due to low demand from the California car company, Reuters reported in August 2018. Tesla last month reported a 36 percent slide in its overall solar sales in the first quarter, adding to previous big drops since the SolarCity acquisition.

New solar panels created from a semiconducting material called cadmium telluride (CdTe) "have been found to produce electricity at lower costs than silicon panels and there has been a dramatic gain in efficiency brought about by adding an element called selenium to the cadmium telluride," reports Phys.Org. "Until now, it was not well understood why selenium increases efficiency but thanks to Tom Fiducia, a Ph.D. Research Student in the Center for Renewable Energy Systems Technology (CREST), and an international team of researchers, the puzzle has been solved." From the report: Their paper, titled "Understanding the role of selenium in defect passivation for highly efficient selenium-alloyed cadmium telluride solar cells," has revealed that selenium works by overcoming the effect of harmful, atomic-scale defects in CdTe panels. This explains the increase of efficiency as electrons (subatomic particles that carry electricity), which are generated when sunlight hits the solar panel, are less likely to be trapped and lost at the defects. This increases the amount of power extracted.

Tom, who is the lead author of the paper, says the team discovered this "unexpected" behavior by measuring how much light is emitted from selenium-containing panels. As selenium is not evenly distributed across the panels, they compared the 'luminescence' emitted from areas where there was little-to-no selenium present and areas where the selenium was very concentrated. Tom explained: "While it seems counter intuitive, good solar cell material that is defect-free is very efficient at emitting light, and so luminesces strongly. We mapped the luminescence emitted from a selenium-containing solar cell at a resolution of around 1/10,000th of a millimeter and compared it to a similarly high-resolution map of the selenium concentration taken on the exact same area of the cell. It is strikingly obvious when you see the data that selenium-rich regions luminesce much more brightly than the pure cadmium telluride, and the effect is remarkably strong." The new-found knowledge could be used to increase the efficiency of cadmium telluride solar panels even further, says Tom. "For instance, this could be by simply increasing the amount of selenium in the devices or altering its distributions within the cell."

An anonymous reader quotes a report from Ars Technica: Cloud Peak Energy, the U.S.' fourth-largest coal mining company, filed for Chapter 11 bankruptcy late last week as the company missed an extension deadline to make a $1.8 million loan payment. In a statement, Cloud Peak said it will continue to operate its three massive coal mines in Wyoming and Montana while it goes through the restructuring process. Colin Marshall, the president and CEO of the company, said that he believed a sale of the company's assets "will provide the best opportunity to maximize value for Cloud Peak Energy."

Cloud Peak was one of the few major coal producers who escaped the significant coal industry downturn between 2015 and 2016. That bought it a reputation for prudence and business acumen. But thinning margins have strained the mining company as customers for thermal coal continue to dry up. Coal-fired electricity is expected to fall this summer, even though summer months are usually boom times for coal plants as air conditioning bolsters electricity demand. That's because cheap natural gas and a boost in renewable capacity have displaced dirtier, more expensive coal. According to the Casper Star Tribune, Cloud Peak shipped 50 million tons of coal in 2018. The paper noted that after the bankruptcy filing, "speculation almost immediately began that Cloud Peak would sell its mines."

Lenovo is launching a new AR-and-VR system targeted at businesses. It's called ThinkReality, and from the looks and description of the device and platform, it looks like a competitor for Microsoft's HoloLens. Engadget reports: There are two parts to the new ThinkReality system -- the AR headset and a software platform. The ThinkReality A6 is a comfortable 380-gram headset with two fisheye cameras on the front, as well as depth sensors and a 13-megapixel RGB sensor. There's also microphones onboard for voice control, and the headset can also detect where you're gazing to optimize resolution or navigation. You'll also be able to interact with your virtual environments using an included 3DoF controller. Untethered, the A6 can last up to four hours with its 6,800mAh battery, and you can still use the device while it's plugged in and charging.

The headset connects to an SSD-sized compute box that contains a Snapdragon 845 CPU running an Android-based platform. There's also an Intel Movidius chips powering waveguide optics here, and each eye on the A6 offers a 40-degree diagonal field of view and 1080p resolution. By comparison, the HoloLens 2 uses a Snapdragon 850 CPU and packs two 2K MEMS displays. Microsoft also squeezes all the computing components into the headset rather than in a separate box like Lenovo does. While I'm not a fan of having to carry around an additional accessory to power a headset, this setup does make the ThinkReality A6 lighter, so it's a compromise I'm willing to make. You can wear the box on a belt clip or an armband, which should make it easy to move around when wearing this setup at work. Lenovo claims this is "one of the lightest fully featured AR headsets in its class," and during a brief trial with a non-working model, I certainly found the A6 lightweight.

An anonymous reader shares a report: It all started over lunch at a Dubai restaurant on March 19, 2017. It was the first time 45-year-old Li, met Costa, the 49-year-old Italian who's often known by peers in the industry as "Captain Magic." During their meal, Costa described a robot hedge fund his company London-based Tyndaris Investments would soon offer to manage money entirely using AI, or artificial intelligence. Developed by Austria-based AI company 42.cx, the supercomputer named K1 would comb through online sources like real-time news and social media to gauge investor sentiment and make predictions on US stock futures. It would then send instructions to a broker to execute trades, adjusting its strategy over time based on what it had learned.

The idea of a fully automated money manager inspired Li instantly. He met Costa for dinner three days later, saying in an email beforehand that the AI fund "is exactly my kind of thing." Over the following months, Costa shared simulations with Li showing K1 making double-digit returns, although the two now dispute the thoroughness of the back-testing. Li eventually let K1 manage $2.5bn -- $250m of his own cash and the rest leverage from Citigroup. The plan was to double that over time. But Li's affection for K1 waned almost as soon as the computer started trading in late 2017. By February 2018, it was regularly losing money, including over $20m in a single day -- Feb. 14 -- due to a stop-loss order Li's lawyers argue wouldn't have been triggered if K1 was as sophisticated as Costa led him to believe.

schwit1 quotes a report from Bloomberg: A plan by California's biggest utility to cut power on high-wind days during the onrushing wildfire season could plunge millions of residents into darkness. And most people aren't ready. The plan by PG&E comes after the bankrupt utility said a transmission line that snapped in windy weather probably started last year's Camp Fire, the deadliest in state history. While the plan may end one problem, it creates another as Californians seek ways to deal with what some fear could be days and days of blackouts. Some residents are turning to other power sources, a boon for home battery systems marketed by Sunrun, Tesla and Vivint Solar. But the numbers of those systems in use are relatively small when compared with PG&E's 5.4 million customers. Meanwhile, Governor Gavin Newsom said he's budgeting $75 million to help communities deal with the threat. PG&E said the city of Calistoga could have its service cut as many as 15 times this fire season, depending on how extreme the weather is. The utility also plans to set up dozens of so-called "resiliency centers," where backup generators can be brought in to run essential services.

"The utility aims to give at least two days warning about a shutoff and has embarked on a public awareness campaign including mailing letters to customers and is working to identify vulnerable residents," reports Bloomberg. "It also will be working to get power restored in a day after a shutoff, though its customers could be out for as many as five days."

At its Accelerate 2019 event in Orlando today, Lenovo previewed "the world's first foldable PC." While we don't know the name, price tag, or ship date, we do know that the foldable PC will be part of Lenovo's flagship ThinkPad X1 line and that it will arrive in 2020. VentureBeat reports: Lenovo backs up its "the world's first foldable PC" claim by saying it looked at laptops sold by major PC manufacturers this month. None shipped more than "1 million units worldwide annually" with foldable screens. Apparently Lenovo is hoping to ship at least 1 million units of its new foldable PC in the first year.

We don't know much about the device yet, and that's on purpose. Tom Butler, Lenovo's ThinkPad marketing director, did say that the company has been working on the device for "several years" with partners Intel, Microsoft and LG. He confirmed that those three have been part of the project from the very beginning. Intel chips and Windows will be powering the foldable ThinkPad. LG is responsible for manufacturing the screen, the highlight of the device. It's a 13.3-inch single OLED 2K display with a 4:3 aspect ratio. It's also a touchscreen and will support pen input. When folded in half, the width of the device is reduced by 50%, as you might expect.

Apple's VP of Apple Pay, Jennifer Bailey, announced new NFC tags that will let iPhone users make purchases simply by tapping their phones against the stickers, without the need to download a special app first. "The company is partnering with Bird scooters, Bonobos clothing store, and PayByPhone parking meters for the initial rollout," reports 9to5Mac. From the report: Apple also announced that inside the Wallet app, users will soon be able to sign up for loyalty cards in one tap, presumably presented to users as recommendations when they make eligible purchases. Right now, physical Apple Pay transactions require bulky terminals like those you find at retail store checkouts. With the new support, an iPhone will know how to read a specially-encoded NFC tag (that can be as inert as a sticker) and automatically show the Apple Pay purchase interface when a user holds their device near it. No third-party apps or other set up required.

The obvious example is a user can ad-hoc top up their miles on a hired electric scooter simply by tapping their phone or watch to a NFC sticker on the bike. For Bonobos, it will enable simpler self-service shopping with the ability to place NFC tags directly onto clothing rails. The new Apple Pay features will be rolling out later this year, presumably with more partners onboard now that the news is public. This is yet another step towards Apple's goal of replacing the wallet.

Amazon is rolling out machines to automate a job held by thousands of its workers: boxing up customer orders. From a report: The company started adding technology to a handful of warehouses in recent years, which scans goods coming down a conveyor belt and envelopes them seconds later in boxes custom-built for each item, two people who worked on the project told Reuters. Amazon has considered installing two machines at dozens more warehouses, removing at least 24 roles at each one, these people said. These facilities typically employ more than 2,000 people. That would amount to more than 1,300 cuts across 55 U.S. fulfillment centers for standard-sized inventory. Amazon would expect to recover the costs in under two years, at $1 million per machine plus operational expenses, they said. The plan, previously unreported, shows how Amazon is pushing to reduce labor and boost profits as automation of the most common warehouse task -- picking up an item -- is still beyond its reach.
