The team's paper, "Solid-State Additive Manufacturing of Porous Ti-6Al-4V by Supersonic Impact," published Nov. 9 in Applied Materials Today. "If we make implants with these kind of porous structures, and we insert them in the body, the bone can grow inside these pores and make a biological fixation," Moridi said. "This helps reduce the likelihood of the implant loosening. And this is a big deal. There are lots of revision surgeries that patients have to go through to remove the implant just because it's loose and it causes a lot of pain." Moridi added: "We only focused on titanium alloys and biomedical applications, but the applicability of this process could be beyond that. Essentially, any metallic material that can endure plastic deformation could benefit from this process. And it opens up a lot of opportunities for larger-scale industrial applications, like construction, transportation and energy."

Rolls Royce Plans 16 Mini-Nuclear Plants For UK (bbc.com) 213
The company's UK "small modular reactor" (SMR) group includes the National Nuclear Laboratory and the building company Laing O'Rourke. The government says new nuclear is essential if the UK is to meet its target of reaching net zero emissions by 2050 -- where any carbon released is balanced out by an equivalent amount absorbed from the atmosphere. But there is a nuclear-sized hole opening up in the energy network. Six of the UK's seven nuclear reactor sites are due to go offline by 2030 and the remaining one, Sizewell B, is due to be decommissioned in 2035. Together they account for around 20% of the country's electricity.
Each plant would produce 440 megawatts of electricity -- roughly enough to power Sheffield -- and the hope is that, once the first few have been made, they will cost around 2 billion pounds each. The consortium says the first of these modular plants could be up and running in 10 years, after that it will be able to build and install two a year. By comparison, the much larger nuclear plant being built at Hinkley Point in Somerset is expect to cost some 22 billion pounds but will produce more than 3 gigawatts of electricity -- over six times as much.

A Self-Taught Garage Inventor Sees His Liquid Air Storage Idea Make the Big Time (cnbc.com) 129
The technology being deployed by Highview Power stems from an idea developed by Peter Dearman, the brains behind the concept of a "liquid air engine." According to the U.K. government, Dearman -- who's been described by the BBC as a "self-taught backyard inventor" -- worked alongside a team from the University of Leeds to develop the idea of "using air as a form of energy storage" when compressed and liquefied. The new site, which is scheduled to open in 2023, will be operated by Highview Power in partnership with another firm called Carlton Power.

Western Digital's Ultrastar DC ZN540 Is the World's First ZNS SSD (tomshardware.com) 30
ZNS SSDs have a number of advantages over traditional block-based SSDs. For one, they place data sequentially into zones and have better control over write amplification, since the software 'knows' what it is dealing with. This means that ZNS SSDs don't need as much overprovisioning as traditional enterprise drives. Many enterprise drives rated for 3DWPD (drive writes per day) reserve up to 28% of their raw capacity for overprovisioning. ZNS needing as little as a tenth of that significantly increases usable SSD capacity. Second, since ZNS manages large zones rather than a bunch of 4KB blocks and doesn't need to perform garbage collection as often as traditional SSDs, it also improves real-world read and write performance. Finally, ZNS substantially reduces DRAM requirements.

Raspberry Pi 4 Can Be Safely Overclocked To 2.15 GHz (hackaday.com) 16
At 2.0 GHz, the Pi 400 got up above 60 C and showed signs of continuing to warm up even after 50 minutes, but it was nowhere near throttling. So I tried 2.2 GHz, at which speed the CPU refused to boot entirely. Backing down to 2.15 GHz, it ran just fine, so I left it for three hours. It settled in at a cozy 62.5 C, which is warm, but well within specs.
I ran the CM4 with the larger heatsink at 1.8 GHz to give some basis for comparison to the cheap heatsinks. What a big difference a big hunk of aluminum makes! It settled in at a comfortable 68 C or so. Even pushing it up to 2.15 GHz and leaving it for a couple hours, it stayed just a hair below 70C (158F) -- a safe margin on the throttling threshold -- and only a few degrees warmer than that huge heat spreader in the Pi 400.Further reading: The Verdict After Hackaday's Teardown of a Raspberry Pi 400: 'Very, Very Slick'.

Hyundai Reportedly In Talks To Buy Softbank-Owned Boston Dynamics (bloomberg.com) 15
A sale of Boston Dynamics would mark another twist in the trajectory of a company that spun out of the Massachusetts Institute of Technology in the early 1990s and operated independently until Google bought it in 2013. It was sold again in 2017, that time to SoftBank. At times, Boston Dynamics has functioned more like a research organization than a business, churning out machines that are technologically advanced and whimsical but unprofitable. That includes Spot, a maneuverable dog-like robot. Videos of its creations regularly rack up millions of views on YouTube; however, the company has said it is not currently generating profits. By contrast, Hyundai makes highly practical industrial robots intended for factory use.

Dish To Shut Down Slingbox, Devices Will Become 'Inoperable' In 2022 (variety.com) 52
In an FAQ about the shutdown, Dish said Slingbox is being discontinued because "We've had to make room for new innovative products so that we can continue to serve our customers in the best way possible." Sling will not be releasing any new products; most authorized resellers have been out of stock of the Slingbox devices "for a couple years," according to the company. Sling Media was acquired by EchoStar in 2007 for $380 million, which at the time was Dish's parent company. Years before Netflix became a streaming powerhouse, the Slingbox "place-shifting" devices let customers watch pay-TV channels over the internet. But the products never became a mainstream category in the way streaming-media players like Roku and Amazon's Fire TV have.

Scientists 3D Print Microscopic Star Trek Spaceship That Moves On Its Own (cnn.com) 52
Microswimmers are small particles that can move through liquid on their own by interacting with their environment through chemical reactions. The platinum coating on the microswimmers reacts to a hydrogen peroxide solution they are placed in, and that propels them through the liquid. "By studying synthetic microswimmers, we would like to understand biological microswimmers," Samia Ouhajji, one of the study's authors, told CNN. "This understanding could aid in developing new drug delivery vehicles; for example, microrobots that swim autonomously and deliver drugs at the desired location in the human body." In their project, the physicists also printed shapes like boats, trimers and helices, with each object's shape affecting their swimming behaviors.

As UK Military Begins Mass Coronavirus Testing, Head of Armed Forces Ponders Robot Soldiers (sky.com) 47
And he shared a thoughtful answer when asked whether the army might try to recruit fewer soldiers. "[W]hat I'm hinting at is that we need to be thinking about how we measure effects in a different way. I mean I suspect we can have an army of 120,000 of which 30,000 might be robots, who knows. But the answer is we need to open our minds to perhaps numbers not determining what we should be doing but rather the effect that we can achieve, is really what we should be looking for."
The armed forces are playing a key role in the government's response to the pandemic, with some 2,000 personnel deployed to Liverpool to help with a mass coronavirus testing programme for the city. "I suspect if that works successfully we might find there are other areas where we need to help in a similar sort of fashion," General Carter said. He said using the military to take over the entire coronavirus testing programme was an option but added that he had confidence in the current set-up at the moment.
The Guardian focused on the robots: Thirty thousand "robot soldiers" could form an integral part of the British army in the 2030s, working alongside humans in and around the frontline, the head of the armed forces said in a television interview on Sunday...
All Britain's armed forces have been engaged in a string of research projects involving small drones or remotely powered land or underwater vehicles, some of which are armed and others for reconnaissance. The Ministry of Defence says its policy is that only humans will be able to fire weapons, although there is growing concern about the potential danger of unrestricted robot warfare, led by the Campaign to Stop Killer Robots.
Technology under development includes the i9 drone, which is powered by six rotors and carries two shotguns. Remotely operated, it is intended to be used to storm buildings, typically an urban warfare situation that generates some of the highest casualties.

HP Replaces 'Free Ink for Life' Plan With '99 Cents a Month Or Your Printer Stops Working' (eff.org) 193
Doctorow writes that it was just the beginning: HP's latest gambit challenges the basis of private property itself: a bold scheme! With the HP Instant Ink program, printer owners no longer own their ink cartridges or the ink in them. Instead, HP's customers have to pay a recurring monthly fee based on the number of pages they anticipate printing from month to month; HP mails subscribers cartridges with enough ink to cover their anticipated needs. If you exceed your estimated page-count, HP bills you for every page (if you choose not to pay, your printer refuses to print, even if there's ink in the cartridges). If you don't print all your pages, you can "roll over" a few of those pages to the next month, but you can't bank a year's worth of pages to, say, print out your novel or tax paperwork. Once you hit your maximum number of "banked" pages, HP annihilates any other pages you've paid for (but continues to bill you every month).
Now, you may be thinking, "All right, but at least HP's customers know what they're getting into when they take out one of these subscriptions," but you've underestimated HP's ingenuity. HP takes the position that its offers can be retracted at any time. For example, HP's "Free Ink for Life" subscription plan offered printer owners 15 pages per month as a means of tempting users to try out its ink subscription plan and of picking up some extra revenue in those months when these customers exceeded their 15-page limit. But Free Ink for Life customers got a nasty shock at the end of last month: HP had unilaterally canceled their "free ink for life" plan and replaced it with "a $0.99/month for all eternity or your printer stops working" plan...
For would-be robber-barons, "smart" gadgets are a moral hazard, an irresistible temptation to use those smarts to reconfigure the very nature of private property, such that only companies can truly own things, and the rest of us are mere licensors, whose use of the devices we purchase is bound by the ever-shifting terms and conditions set in distant boardrooms. From Apple to John Deere to GM to Tesla to Medtronic, the legal fiction that you don't own anything is used to force you to arrange your affairs to benefit corporate shareholders at your own expense. And when it comes to "razors and blades" business-model, embedded systems offer techno-dystopian possibilities that no shaving company ever dreamed of: the ability to use law and technology to prevent competitors from offering their own consumables. From coffee pods to juice packets, from kitty litter to light-bulbs, the printer-ink cartridge business-model has inspired many imitators.
HP has come a long way since the 1930s, reinventing itself several times, pioneering personal computers and servers. But the company's latest reinvention as a wallet-siphoning ink grifter is a sad turn indeed, and the only thing worse than HP's decline is the many imitators it has inspired.

The Verdict After Hackaday's Teardown of a Raspberry Pi 400: 'Very, Very Slick' (hackaday.com) 71
Hackady's verdict? The new Raspberry Pi 400 "is very, very slick." Inside, there's a flat-flex that connects the keyboard, and you see that big aluminum heat sink. It's almost the full size of the keyboard, and it's thick and heat-taped to the CPU. You know it means business. It's also right up against the aluminum bottom of the keyboard, suggesting it could get radiative help that way, and maybe keep your fingers warm in the winter. (I didn't feel any actual heat, but it's gotta go somewhere, right? There are also vents in the underside of the case.)
Four PZ1 screws and a little bit of courage to unstick the pad get you underneath the heat spreader to find, surprise!, a Raspberry Pi 4. This was a little anticlimactic, as I've just spent a couple weeks looking over the schematics for my review of the new Compute Module 4, and it's just exactly what you'd expect. It's a Raspberry Pi 4, with all the ports broken out, inside a nice keyboard, with a beefy heat spreader. Ethernet magnetics sit on one side, and the wireless module sits on the other. That's it!
"[C]ombine this with a small touch screen, and run it all off of a 5 V power pack, and you've got a ton of portable computing in a very small package.
"If you're not mousing around all the time anyway, there's a certain streamlined simplicity here that's mighty tempting."

A Biden Victory Positions America For a 180-Degree Turn On Climate Change (seattletimes.com) 251
destinyland shares their report: While some of Biden's most sweeping programs will encounter stiff resistance from Senate Republicans and conservative attorneys general, the United States is poised to make a 180-degree turn on climate change and conservation policy. Biden's team already has plans on how it will restrict oil and gas drilling on public lands and waters; ratchet up federal mileage standards for cars and SUVs; block pipelines that transport fossil fuels across the country; provide federal incentives to develop renewable power; and mobilize other nations to make deeper cuts in their own carbon emissions... Biden has vowed to eliminate carbon emissions from the electric sector by 2035 and spend $2 trillion on investments ranging from weatherizing homes to developing a nationwide network of charging stations for electric vehicles.
That massive investment plan stands a chance only if his party wins two Senate runoff races in Georgia in January; otherwise, he would have to rely on a combination of executive actions and more-modest congressional deals to advance his agenda.
Still, a number of factors make it easier to enact more-ambitious climate policies than even four years ago. Roughly 10% of the globe has warmed by 2 degrees Celsius (3.6 degrees Fahrenheit), a temperature rise the world has pledged to avoid. The price of solar and wind power has dropped, the coal industry has shrunk, and Americans increasingly connect the disasters they're experiencing in real time — including more-intense wildfires, hurricanes and droughts — with global warming. Biden has made the argument that curbing carbon will produce high-paying jobs while protecting the planet...
Some of the new administration's rules could be challenged in federal court, which have a number of Trump appointees on the bench. But even some conservative activists said that Biden could enact enduring policies, whether by partnering with Congress or through regulation... The new administration may be able to broker compromises with key industries that have experienced regulatory whiplash in the past decade, including the auto industry and power sector, while offering tax breaks for renewable energy that remain popular with both parties. And Biden can rebuild diplomatic alliances that will spur foreign countries to pursue more-ambitious carbon reductions...
Biden's advisers have said that they plan to elevate climate change as a priority in departments that have not always treated it as one, including the Transportation, State and Treasury departments. It will influence key appointments, affecting everything from overseas banking and military bases to domestic roads and farms.... Biden's pledge to achieve a carbon-free U.S. power sector within 15 years would mean the closing or revamping of nearly every coal- and gas-fired power plant around the country, and the construction of an unprecedented number of new wind turbines and solar farms. On top of that, engineers still need to devise a better way of storing energy when the sun is not shining or the wind is not blowing.
"If I were advising Biden on energy, my first three priorities would be storage, storage and storage," said Sen. Angus King, I-Maine, who worked in the alternative energy businesses before running for office.

Tesla Project To Install Another Giant Battery In Australia (bloomberg.com) 63
Installing the new system in Australia's second-most populous state will help to modernize and stabilize the local grid, which is targeting 50% of its power to come from renewable sources by 2030, Neoen said Thursday in a media release. The Paris-based company is targeting the battery to be operational by the end of 2021. [...] Victoria's grid still relies heavily on aging coal-fired plants, which have become increasingly unreliable during periods of extreme heat. The state has experienced power outages in recent summers as the system struggled to cope with a surge in demand as businesses and households cranked up air conditioners. Neoen's new project in Victoria will be supported by a 250 megawatt grid services contract with the Australian Energy Market Operator, and will also partner with network provider AusNet Services, the company said.

Bentley Will Ditch Internal Combustion Engines By 2030 (arstechnica.com) 114
Bentley already introduced a plug-in hybrid EV version of the Bentayga SUV and next year it plans to add another pair of PHEVs to its roster -- presumably the Continental GT coupe and Flying Spur sedan. In 2025, the company plans to introduce a battery electric vehicle; Bentley CEO Adrian Hallmark told Autoweek that "you've got to pick a point in time where battery power density, especially for bigger cars, is the liberator for us. We've always said that the mid-2020s is the time when you can expect to see 120-plus kilowatt-hour batteries coming through the supply chain." 2025 will also be the last year you'll be able to buy a Bentley that doesn't plug in, because in 2026 the brand is dropping everything other than PHEVs and BEVs. In 2030, those PHEVs will be gone, too, leaving just BEVs to wear the winged B badge with pride. Along the way, Bentley is also pledging to reduce its factory's environmental impact and go plastic neutral.

Several US Utilities Back Out of Deal To Build Novel Nuclear Power Plant (sciencemag.org) 207
However, critics of the project say the developments underscore that the plant, which is designed by NuScale Power and would be built at the Department of Energy's (DOE's) Idaho National Laboratory, will be untenably expensive. M. V. Ramana, a physicist who works on public policy at the University of British Columbia, Vancouver, says he's not surprised that so many utilities have opted out of the project. The question, he says, is why so many are sticking with it. "They ought to be seeing the writing on the wall and getting out by the dozens," he says.
