Who's Actually To Blame For the Texas Power Disaster? (cnn.com) 663

With millions of Texans still without power in the wake of a winter storm and frigid temperatures, everyone is looking for someone to blame. From a report, shared by a reader: Many Democrats are blaming Gov. Greg Abbott (R) for failing to adequately prepare for the storm. Many conservatives are blaming the environmental movement -- insisting that frozen wind turbines show the limits of alternative energy sources. (This is a gross exaggeration.) But the primary fall guy is the Electric Reliability Council of Texas (ERCOT), an independent organization that operates Texas' power grid. "This was a total failure by ERCOT," said Abbott on Tuesday. "These are the experts. These are engineers in the power industry. These aren't bureaucrats or whatever the case may be. These are specialists, and government has to rely upon on these specialists to be able to deliver in these types of situations." The story, as you might guess, is actually slightly more complicated than that. It's rooted in Texans' views of their state as a quasi-independent country -- and a desire to have as little federal interference in their lives as possible. Yes, there are politics at the root of this. "Texas' secessionist inclinations have at least one modern outlet: the electric grid," wrote the Texas Tribune back in 2011.

To understand what is happening right now in Texas -- and who's to blame -- you have to go back to 1935, when President Franklin Delano Roosevelt signed the Federal Power Act, which governed electricity sharing and sales between the states. Basically, it allowed the federal government to regulate states who brought power in from outside their state lines. Texas, never a fan of federal intrusion, set up its own power grid system -- split between northern and southern Texas -- to avoid any federal involvement. That led eventually to the formation of ERCOT in 1970 and this strange fact: There are three power grids in the United States -- the eastern power grid, the western power grid and, well, Texas. Yes, you read that right. Texas has its own power grid. Because it is Texas. And while being independent from the yoke of federal regulation has always been a point of pride for Texas, the limits of that strategy are being realized now. See, because Texas -- or at least 90% of the state -- is controlled by ERCOT, they can't simply borrow power from either the eastern or western power grids. That's never been a problem before because Texas has always been able to generate more power than its citizens need. But the reality is that Texas is an electricity island, which isn't a problem until the lights go out, and you don't have enough power in the state to turn them back on. Now, there's no question that ERCOT bears some blame here, too.

Google, Microsoft, Qualcomm Protest Nvidia's Arm Acquisition (bloomberg.com) 47

Some of the world's largest technology companies are complaining to U.S. antitrust regulators about Nvidia's acquisition of Arm because the deal will harm competition in an area of the industry that is vital to their businesses. Alphabet's Google, Microsoft and Qualcomm are among companies worried about the $40 billion deal and are asking antitrust officials to intervene, Bloomberg News reported Friday, following up on CNBC's report from earlier today that talked only about Qualcomm's efforts. At least one of the companies wants the deal killed, Bloomberg added. From the report: The acquisition would give Nvidia control over a critical supplier that licenses essential chip technology to the likes of Apple, Intel, Samsung Electronics, Amazon.com and China's Huawei Technologies. U.K.-based Arm is known as the Switzerland of the industry because it licenses chip designs and related software code to all comers, rather than competing against semiconductor companies. The concern is that if Nvidia owns Arm, it could limit rivals' access to the technology or raise the cost of access.

Qualcomm Objects To Nvidia's $40 Billion Arm Acquisition (cnbc.com) 12

U.S. chipmaker Qualcomm has told regulators around the world that it is against Nvidia's $40 billion acquisition of British chip designer Arm, CNBC reported Friday, citing sources familiar with the matter. From the report: The company has told the Federal Trade Commission, the European Commission, the U.K.'s Competition and Markets Authority and China's State Administration for Market Regulation that it has concerns about Nvidia buying Arm, which is currently owned by Japanese tech giant SoftBank. The FTC's investigation has moved to a "second phase" and the U.S. regulator has asked SoftBank, Nvidia and Arm to provide it with more information, according to two sources who are familiar with the deal but wished to remain anonymous due to the private nature of the discussions. Complying with the information request is likely to take many months as several large documents will need to be produced, the sources said. During the second phase, the FTC will also engage with other companies who may have relevant information that could help it to make a decision, they added.

Bitcoin Consumes 'More Electricity Than Argentina' (bbc.com) 355

Thelasko shares a report from the BBC: Bitcoin uses more electricity annually than the whole of Argentina, analysis by Cambridge University suggests. 'Mining' for the cryptocurrency is power-hungry, involving heavy computer calculations to verify transactions. Cambridge researchers say it consumes around 121.36 terawatt-hours (TWh) a year -- and is unlikely to fall unless the value of the currency slumps. Critics say electric-car firm Tesla's decision to invest heavily in Bitcoin undermines its environmental image.

The online tool has ranked Bitcoin's electricity consumption above Argentina (121 TWh), the Netherlands (108.8 TWh) and the United Arab Emirates (113.20 TWh) - and it is gradually creeping up on Norway (122.20 TWh). The energy it uses could power all kettles used in the UK for 27 years, it said. However, it also suggests the amount of electricity consumed every year by always-on but inactive home devices in the US alone could power the entire Bitcoin network for a year.
"Bitcoin is literally anti-efficient," David Gerard, author of Attack of the 50 Foot Blockchain, explained. "So more efficient mining hardware won't help -- it'll just be competing against other efficient mining hardware. This means that Bitcoin's energy use, and hence its CO2 production, only spirals outwards. It's very bad that all this energy is being literally wasted in a lottery."

In regard to Tesla's decision to buy bitcoin, Mr Gerard added: "Elon Musk has thrown away a lot of Tesla's good work promoting energy transition. This is very bad... I don't know how he can walk this back effectively. Tesla got $1.5 billion in environmental subsidies in 2020, funded by the taxpayer. It turned around and spent $1.5 billion on Bitcoin, which is mostly mined with electricity from coal. Their subsidy needs to be examined."

Biden Team Pledges Aggressive Steps To Address Chip Shortage (yahoo.com) 175

The Biden administration is working to address the global semiconductor shortage that has caused production halts in U.S. industries including autos, White House Press Secretary Jen Psaki said. From a report: The administration is identifying choke points in supply chains and discussing an immediate path forward with businesses and trading partners, Psaki told reporters at the White House on Thursday. In the longer term, policy makers are looking for a comprehensive strategy to avoid bottlenecks and other issues the semiconductor industry has been facing for years. President Joe Biden is expected to sign an executive order directing a government-wide supply chain review for critical goods in the coming weeks, with the chip shortage a central concern behind the probe. The order will compel a 100-day review led by the National Economic Council and National Security Council focused on semiconductor manufacturing and advanced packaging, critical minerals, medical supplies and high-capacity batteries, such as those used in electric vehicles, two people familiar with the draft said. Additional supply-chain assessments are expected within a year, focused on critical products -- materials, technology and infrastructure -- and other materials tied to defense, public health, telecommunications, energy and transportation.

Chrome Will Soon Lose Support For Some Ancient CPUs (techspot.com) 141

If you're one of the few people still using a PC with an x86 processor more than 15 years old, here's another reason to upgrade: the devices will not work with future Chrome releases, starting with version 89 of the world's most popular browser. TechSpot reports: The Chromium development team announced that CPUs older than the Intel Core 2 Duo and AMD Athlon 64 would not work with Chrome 89 and future versions as they do not meet the new minimum instruction set requirement of SSE3 (Supplemental Streaming SIMD Extensions 3) support. So, if you are still sporting an Intel Atom or Celeron M CPU, you'll soon be counting Chrome as one of the many programs that are incompatible with your potato-like rig. The devices will no longer attempt to install the browser, while running it will result in the software crashing. It's noted that the change only affects Windows as Chrome OS, Android and, Mac already require SSE3 support.

The Nintendo Switch Can Now Run Android 10, Unofficially 20

Thanks to the hard work of the SwitchRoot team, it's now possible to enjoy an Android 10-based LineageOS 17.1 port on your Nintendo Switch console. XDA Developers reports: The Android 10 release is based on the LineageOS 17.1 build for the NVIDIA SHIELD TV and brings many improvements over the previous release, including a much-needed deep sleep mode so the OS doesn't murder your console's battery life. It's also generally faster and more responsive than the previous Android 8.1 Oreo version, according to the SwitchRoot team.

The ROM comes in two flavors: a Tablet build that offers a standard Android UI with support for all apps and an Android TV build that supports both docked and undocked use cases but has more limited app support. The former is recommended if you primarily use your Nintendo Switch while undocked, while the latter will offer a much-better docked experience. As for bugs and broken things, the developer says games built for the SHIELD (Half-Life 2, Tomb Raider, etc.) aren't supported, and you might notice some stuttering with Bluetooth audio. Some apps also may not support the Joy-Con D-Pad.

In order to install this build, you'll need an RCM-exploitable Nintendo Switch, a USB-C cable, a high-speed microSD card (formatted to FAT32), and a PC. If you already have the Android 8.1 Oreo build installed on your SD card, just make sure to back up your data before installing the Android 10 build, as flashing this new ROM will wipe all data. After installing the ROM itself, be sure to flash the Google Apps package, Alarm Disable ZIP, and Xbox Joycon Layout ZIP if you use an Xbox controller.

Qualcomm Unveils the First 10-Gigabit 5G Modem (engadget.com) 12

Qualcomm has unveiled the X65, what it says is the "world's first" 10-gigabit 5G modem. Engadget reports: While that's not hugely faster than the 7.5Gbps of the X60, it promises a speed that was previously reserved for Ethernet and other wired connections. The X65 also boasts some helpful functional improvements, including AI-based antenna tuning that better responds to hand grips. You'll also find better power-saving measures and a newer "Smart Transmit" system that boots upload speeds and overall coverage.

The X65 is currently sampling to customers and should reach shipping devices in 2021, although Qualcomm didn't name customers. Don't count on it reaching many phones, at least not at first. [...] While it will support "premium smartphone experiences," you're more likely to see it used in laptops, fixed 5G broadband or similar areas where a separate modem isn't an issue.

The iPhone 12 Mini Was Apple's 2020 Sales Flop (arstechnica.com) 73

An anonymous reader quotes a report from Ars Technica: Bad news for lovers of smaller phones: the iPhone 12 mini has sold poorly compared to other phones in the iPhone 12 lineup -- poorly enough that analysts wonder whether Apple will remain committed to the smaller phone design moving forward. A data firm called Counterpoint Research found that the iPhone 12 mini accounted for just 5 percent of overall sales from the company's smartphone lineup in early January. And J.P. Morgan analyst William Yang told Reuters that screens under 6 inches now account for only 10 percent of smartphones sold industry-wide.

The data from Counterpoint is not the first to tell this story. Consumer Intelligence Research Partners (CIRP) broke down iPhone 12 lineup sales in detail last month. They found that the iPhone 12 Pro and 12 Pro Max made up about 20 percent of sales from the larger iPhone 12 lineup during the launch window, while the non-Pro, 6.1-inch iPhone 12 accounted for 27 percent. But they also said the iPhone 12 mini "likely disappointed Apple" with only 6 percent of sales during the period measured -- pretty close to the number Counterpoint shared a couple of months later.

While all this data shows that the iPhone 12 mini has underperformed, it doesn't tell us why. According to CIRP's data, the also-small iPhone SE performed a little better (likely due to its significantly lower price) but it still didn't make up a huge chunk of sales. So while it's possible that the iPhone 12 mini's slow sales are partially a result of cannibalization by the cheaper SE, small phones are clearly not doing well in general. There are a lot of reasons small phones are less popular now. For one thing, users are consuming more rich media content. Many people watch as much TV and film on their phones as they do on their TVs now, and some social media platforms like TikTok and Snapchat are focused on rich media that may be more enjoyable to some on a larger display. But if anything, these sales numbers make the future of one-handed smartphones look even dimmer than before.

Aurora 7 Laptop With 7 Screens Unveiled (gizmodo.com) 52

Sometimes one screen isn't enough and you need two. Sometimes even two doesn't get the job done, and you need three. If your job requires seven screens, a UK firm now has you covered. Gizmodo reports: The Aurora 7 laptop seems lifted straight from the imagination of a Hollywood prop builder working on a bad hacker flick. But with seven foldout screens, there's little chance anyone could actually use this beast on their laps. It's a mobile transforming workstation for those who need more screen real estate than they have room for monitors. Created by a UK company called Expanscape, the Aurora 7 is very much just a prototype at this stage in the game (as is evident by the extensive use of 3D-printed parts), but it's designed to be true mobile workstation for everyone from developers to content creators to even well-funded gamers wanting a more immersive experience from a computer they don't have to leave at home. Powered by an Intel i9 9900K processor backed by 64GB of DDR4 RAM and an NVIDIA GTX 1060 series graphics card, the Aurora 7 also comes with 2TB of hard drive storage and an additional 2.5 TB of SSD storage, plus all the ports you could ever need to expand its capacity even further. But the star of the show is the complicated mosaic of screens which includes four 17.3-inch 4K (3840 x 2160) LCDs -- two in portrait mode and two in landscape -- as well as three smaller 7-inch screens all pushing 1920 x 1200 pixels, with one located in the laptop's wrist rest. The laptop has a battery life of one hour. No word on pricing or when it starts shipping.

German Institute Develops 'Powerpaste' That Stores Hydrogen Energy At 10x the Density of a Lithium Battery (hackaday.com) 124

A German research organization has developed a magnesium-based "Powerpaste" with an energy density ten times more than current battery technology. Hackaday reports: We've been promised hydrogen-powered engines for some time now. One downside though is the need for hydrogen vehicles to have heavy high-pressure tanks. While a 700 bar tank and the accompanying fuel cell is acceptable for a city bus or a truck, it becomes problematic with smaller vehicles, especially ones such as scooters or even full-sized motorcycles. The Fraunhofer Institute wants to run smaller vehicles on magnesium hydride in a paste form that they call POWERPASTE.

The idea is that the paste effectively stores hydrogen at normal temperature and pressure. At 250C, the paste decomposes and releases its hydrogen. While your motorcycle may seem hot when parked in the sun, it isn't getting quite to 250C. Interestingly, the paste only provides half the available hydrogen. The rest is from water added start a reaction to release the hydrogen. Fraunhofer claims the energy density available is greater than that of a 700 bar tank in a conventional hydrogen system and ten times more than current battery technology.

One thing that's attractive is that the paste is easy to store and pump. A gas station, for example, could invest $20-30,000 and dispense the paste from a metal drum to meet low demand and then scale up as needed. A hydrogen pumping setup starts at about $1.2 million. Fraunhofer is building a pilot production plant that will produce about four tons of the material a year.

Intel Benchmarks Say Apple's M1 Isn't Faster (pcworld.com) 260

PCWorld reviews Intel's recently-released benchmarks claiming Apple's M1 isn't faster than their 11th gen Core i7-1185G7 processor, among other things. Here are the claims Intel makes (visit the article to read PCWorld's "take" on each claim): MacBook M1 is slower than Core i7: Intel says in the WebXPRT 3 test, using the same version of Chrome for both the Core i7 system as well as the Arm-native MacBook, Intel takes the lead. The Intel chip was largely ahead in WebXPRT 3, and the x86 chip was nearly three times faster in finishing the photo enhancement test. Intel doesn't just use WebXPRT 3, though. It also shows the Core i7 pummeling the M1 in a PowerPoint-to-PDF export, and in multiple Excel macros by a factor of 2.3x. And yes, Intel used the Arm-native versions of Office for its tests.

Core i7 Crushes M1 in AI: For content creation tasks, Intel showed the Core i7 to be about 1.12x faster than the M1 in performing a 4K AVC-to-HEVC/H.265 file conversion. In this benchmark, they had the MacBook using the M1-native version of Handbrake. But the real destruction happens once you get to Topaz Lab's Gigapixel AI and Denoise AI, with the Intel Core chip crushing the M1 in AI-based noise removal and enlargement. Or maybe "crushing" is too nice a term, as it's more like the Core i7 outpaces the M1 by so much, the M1 wishes it had never been designed.

M1 doesn't support all the features: Intel also gives itself the lead in Adobe Premiere Pro, using the beta M1 native version in Auto Reframe, exporting to H.264 and H.265. They're decent wins, but come on, the code is still in beta for the Mac. That said, Intel points out that important features like Content Aware Fill are outright disabled on the beta version, and that's a concern. If the native version of Photoshop comes out, and there are critical features missing from it, that's a huge problem for Apple (and Adobe).

You can't be faster if you can't run it: For gaming, we see a bit of a back and forth between the Apple M1 and Core i7 in games that actually work on the MacBook. Intel doesn't let it end there, though, and decides to embarrass Apple further by showing the numerous games where the MacBook scores a 0 because game support just doesn't exist. Intel points out that "countless more" games "don't run on the M1," and then for good measure, it rushes Apple's bench with a list 10 more games you can't play on the M1 MacBook: Overwatch, Crysis Remastered, Halo MCC, Red Dead Redemption 2, PUBG, Monster, Hunter World, Doom Eternal, Microsoft Flight Simulator 2020, Apex Legends, and Rainbow Six Siege.

MacBook wouldn't win Evo certification: You know that fancy Intel Evo program that tries to improve laptop performance in key areas that annoy consumers? Well, Intel pretty much says that if Apple submitted the M1 MacBook to the same program that Asus, Dell, HP, Lenovo, MSI, Acer and others go through, it would be rejected. The reason? Intel says the M1 MacBook is too slow in doing things that anger consumers, such as "switch to Calendar" in Outlook, "start video conference Zoom" and "select picture menu" in PowerPoint.

Great battery life?: Perhaps the most shocking claim Intel showed deals with battery life. While performance tests can be cherry picked by those looking to prove an outcome, battery life usually can't be disputed. Apple's official claim gives the M1 MacBook up to 18 hours of battery life using Apple TV app to watch a 1080p video with the brightness set to "8 clicks from the bottom." Apple also claims up to 15 hours browsing 25 "popular" websites with the same "8 clicks" criteria. When Intel pitted a MacBook Air M1 against an Acer Swift 5 with a Core i7-1165G7, however, it found both basically dead even. The MacBook Air came in at 10 hours and 12 minutes, and the Acer Swift 5 lasted 10 hours and 6 minutes. The difference? Intel said it used Safari to watch a Netflix stream with tabs open with the screen set to a relatively bright 250 nits. On the Acer, Safari was subbed out for Chrome, but the brightness and Netflix remained the same. Intel did add that Apple's "8 clicks up" is about 125 nits of brightness on the MacBook Air which is pretty dim.

All kinds of things just don't work on the M1: Intel didn't just get into the performance of the M1. It also said it found the MacBook Pro had serious shortcomings, such as an inability to use more than one display with a Thunderbolt dock. And while the PC can use gaming headsets, eGPUs, a third-party finger print reader, Wacom Drawing tablet and Xbox Controller, Intel said it found the MacBook Pro simply doesn't work with eGPUs, and had multiple issues with other devices. That's just hardware incompatibility. Intel's rap battle with Apple also highlights issues with plug-ins for Ableton, Bitwig Studio, Avid Pro Tools, FL Studio, Motu and many others.

MIT Is Building a 'One-Stop Shop' For 3D-Printing Robots (techcrunch.com) 6

An anonymous reader quotes a report from TechCrunch: MIT's CSAIL department this week showcased "LaserFactory," a new project that attempts to develop robotics, drones and other machines than can be fabricated as part of a "one-stop shop." The system is comprised of a software kit and hardware platform designed to create structures and assemble circuitry and sensors for the machine.

A more fully realized version of the project will be showcased at an event in May, but the team is pulling back the curtain a bit to show what the concept looks like in practice. Here's a breakdown from CSAIL's page: "Let's say a user has aspirations to create their own drone. They'd first design their device by placing components on it from a parts library, and then draw on circuit traces, which are the copper or aluminum lines on a printed circuit board that allow electricity to flow between electronic components. They'd then finalize the drone's geometry in the 2D editor. In this case, they'd use propellers and batteries on the canvas, wire them up to make electrical connections, and draw the perimeter to define the quadcopter's shape."
For more information, CSAIL has released an accompanying video showing the machine in action. A technical paper is available here.

First 3D-Printed House Goes On Sale, Foreshadowing Faster, Cheaper Homebuilding (cnn.com) 134

"A company says it has listed the first 3D printed house in the United States for sale," reports CNN. "This is the future, there is no doubt about it," says Kirk Andersen, the director of operations at SQ4D Inc.

SQ4D uses automated building methods, or 3D printing, to build structures and homes... The company can set up its Autonomous Robotic Construction System at a build site in six to eight hours. It then lays concrete layer by layer, creating footing, the foundation of a house and the interior and exterior walls of the structure... "The cost of construction is 50% cheaper than the cost of comparable newly-constructed homes in Riverhead, New York, and 10 times faster," said Stephen King, the Zillow Premier agent who has the 3D house listing...

"I want people to not be afraid of automation...it is just a different tool and different method. But it's still the same product; we are still building a house at the end of the day," says Kirk Andersen, the director of operations at SQ4D...

"We can make things more affordable and safer. We can use the technology to tackle homelessness, and aid in disaster relief in an eco-friendly way," Andersen said.

Denmark Strikes Deal On Artificial Wind Energy Island (theguardian.com) 48

An anonymous reader quotes a report from The Guardian: Denmark's government has agreed to take a majority stake in a 25 billion euro artificial "energy island," which is to be built 50 miles (80km) offshore, in the middle of the North Sea. The island to the west of the Jutland peninsula will initially have an area of 120,000 sq meters -- the size of 18 football pitches -- and in its first phase will be able to provide 3m households with green energy. It will be protected from North Sea storms on three sides by a high sea wall, with a dock for service vessels taking up the fourth side.

In a broad deal struck on Wednesday night, the Social Democrat government agreed with its support parties and the rightwing opposition that the state should hold a 51% stake in the island, with the remainder held by the private sector. The project builds on an inter-party deal struck in June on energy policy, in which the parties agreed to construct two wind energy hubs, one artificial and another centered on the Baltic island of Bornholm. The two hubs will initially support 5GW of wind generation and triple Denmark's current installed offshore wind. The capacity will later be expanded to as much as 12GW.

IBM Quantum Computers Now Finish Some Tasks In Hours, Not Months (engadget.com) 34

IBM has found a way to combine a new program execution environment, Qiskit, with a balance of "classical" and quantum computing to deliver a 100 times speedup for tasks that depend on iterative circuit execution. Computations that take months now will take mere hours, IBM said. Engadget reports: Qiskit by itself allows more circuits to run at a "much faster" rate, and can store quantum programs so that other users can run them. However, it also uploads programs to conventional hardware sitting next to the quantum machines. Before you ask, this isn't really cheating -- the move is meant to cut the latency between a user's computer and the quantum chip.

IBM expects to release Qiskit sometime in 2021. Its roadmap also has quantum systems handling a wider range of circuits, and thus a wider range of computing challenges, by 2022. New control systems and libraries in 2023 will help IBM reach its goal of running systems with 1,000 or more qubits, taking the company closer to a "quantum advantage" where the technology can handle at least some tasks more efficiently or cost-effectively than traditional hardware.

Mac Utility Homebrew Finally Gets Native Apple Silicon and M1 Support (arstechnica.com) 43

An anonymous reader quotes a report from Ars Technica: Homebrew now supports Apple Silicon natively, albeit not with every package. The volunteer Homebrew team made the announcement on the Homebrew blog alongside today's release. While the native support is not yet comprehensive, it bridges the gap significantly, and users can still run Terminal via Rosetta 2 to do what they can't yet while running natively on Apple Silicon. The Homebrew blog post says "we welcome your help" in providing bottles for all packages moving forward.

Here's the full bullet point on Apple Silicon in the Homebrew 3.0.0 release notes: "Apple Silicon is now officially supported for installations in /opt/homebrew. formulae.brew.sh formula pages indicate for which platforms bottles (binary packages) are provided and therefore whether they are supported by Homebrew. Homebrew doesn't (yet) provide bottles for all packages on Apple Silicon that we do on Intel x86_64 but we welcome your help in doing so. Rosetta 2 on Apple Silicon still provides support for Intel x86_64 in /usr/local."

Nvidia is Requiring Laptop Makers To Be More Transparent About RTX 30-series Specs (theverge.com) 15

Nvidia is now requiring, not just encouraging, companies selling laptops with its new RTX 30-series graphics chips to be more transparent about the kind of power people can expect. From a report: Nvidia tells The Verge these companies will have to disclose specific clock speed stats and total graphics power on online product pages -- all of which tells people everything they need to know about a laptop's graphics potential, for better or worse. However, companies won't have to mention that these chips are Max-Q variants because, according to an Nvidia spokesperson, "Max-Q is no longer part of the GPU name." Rather, Max-Q is now solely used to communicate that a laptop with an RTX 30-series graphics chip ships with efficiency features like Whisper Mode 2, Dynamic Boost 2, and Advanced Optimus. Previously, seeing Max-Q branding made it easy to determine a laptop's general performance without having to know its specific clock speeds. It's encouraging to see Nvidia no longer allows companies to hide this vital information from marketing materials. It should go far enough in helping buyers make an educated purchase without having to wait on reviewers and early adopters to report on the specs.

The Empire State Building and Its Related Buildings Are Now Powered By Wind (thehill.com) 192

The iconic Empire State Building that has crowned Midtown Manhattan since the early 1930s is now a game changer in American architecture in a different way: by becoming completely powered with renewable energy. The Hill reports: Announced on Wednesday, Empire State Realty Trust (ESRT) confirmed that it struck a three-year contract with Green Mountain Energy to power its entire commercial real estate portfolio with renewable wind electricity. This reportedly makes ESRT the largest user of green power in U.S. real estate. Green Mountain Energy, based out of Vermont, is a leading sustainable energy provider, offering plans with public and private real estate groups using solar panels and wind turbines as the source of electricity.

ESRT controls more than 10.1 million square feet of real estate, all of which will be powered by renewable energy for the next three years. This switch will spare about 450 million pounds of carbon dioxide emissions from entering the atmosphere. This is roughly the equivalent of every New York State household turning off all of their lights for an entire month. Prior to this partnership, the Empire State Building underwent renovations a decade ago to help convert the building to be more environmentally friendly, resulting in a 40 percent reduction in energy usage prior to the contract with Green Mountain.

A New Lens Technology Is Primed To Jump-Start Phone Cameras (wired.com) 50

An anonymous reader quotes a report from Wired: A new company called Metalenz, which emerges from stealth mode today, is looking to disrupt smartphone cameras with a single, flat lens system that utilizes a technology called optical metasurfaces. A camera built around this new lens tech can produce an image of the same if not better quality as traditional lenses, collect more light for brighter photos, and can even enable new forms of sensing in phones, all while taking up less space.

Instead of using plastic and glass lens elements stacked over an image sensor, Metalenz's design uses a single lens built on a glass wafer that is between 1x1 to 3x3 millimeter in size. Look very closely under a microscope and you'll see nanostructures measuring one-thousandth the width of a human hair. Those nanostructures bend light rays in a way that corrects for many of the shortcomings of single-lens camera systems. The core technology was formed through a decade of research when cofounder and CEO Robert Devlin was working on his PhD at Harvard University with acclaimed physicist and Metalenz cofounder Federico Capasso. The company was spun out of the research group in 2017.

Light passes through these patterned nanostructures, which look like millions of circles with differing diameters at the microscopic level. The resulting image quality is just as sharp as what you'd get from a multilens system, and the nanostructures do the job of reducing or eliminating many of the image-degrading aberrations common to traditional cameras. And the design doesn't just conserve space. Devlin says a Metalenz camera can deliver more light back to the image sensor, allowing for brighter and sharper images than what you'd get with traditional lens elements. Another benefit? The company has formed partnerships with two semiconductor leaders (that can currently produce a million Metalenz "chips" a day), meaning the optics are made in the same foundries that manufacture consumer and industrial devices -- an important step in simplifying the supply chain. Metalenz will go into mass production toward the end of the year. Its first application will be to serve as the lens system of a 3D sensor in a smartphone. (The company did not give the name of the phone maker.)
