An anonymous reader quotes a report from Ars Technica: There's a new fast-charging network coming to North America. It's called Greenlane, and it's a $650 million joint venture between Daimler, NextEra Energy Resources, and a BlackRock investment fund. But it's unlikely you'll recharge your passenger EV at a Greenlane site any time soon -- this new network is being designed specifically for medium- and heavy-duty commercial EVs. [...] Based on the company's renderings, Greenlane's sites will be much more comfortable for big rigs. The first of these sites will be in Southern California, and Greenlane says it will build out a network along critical freight routes on the East and West Coasts, as well as in Texas. To begin with, the company will focus on commercial EV recharging, but refueling infrastructure for hydrogen fuel cell EVs will follow. In time, Greenlane plans to add chargers for passenger (or light-duty) EVs. "Greenlane is designed to begin to tackle one of the greatest hurdles to the trucking industry's decarbonization -- infrastructure," said John O'Leary, Daimler Trucks North America's president and CEO.

"The nation's fleets can only transform with the critical catalyst of publicly accessible charging designed to meet the needs for medium- and heavy-duty vehicles. Together with our strong partners, BlackRock and NextEra Energy Resources, we are launching Greenlane to address the unique demands of the industry, support our mutual customers, and provide a dual benefit to all electric vehicle drivers who will be able to utilize this new network. We're excited to take this next step and look forward to sharing more of Greenlane's plans in the future," O'Leary said.

An anonymous reader quotes a report from Engadget: The controversial EARN IT Act, first introduced in 2020, is returning to Congress after failing twice to land on the president's desk. The Eliminating Abusive and Rampant Neglect of Interactive Technologies Act, (EARN IT) Act is intended to minimize the proliferation of Child Sexual Abuse Material (CSAM) throughout the web, but detractors say it goes too far and risks further eroding online privacy protections.

Here's how it would work, according to the language of the bill's reintroduction last year. Upon passing, EARN IT would create a national commission composed of politically-appointed law enforcement specialists. This body would be tasked with making a list of best practices to ostensibly curb the digital distribution of CSAM. If online service providers do not abide by these best practices, they would potentially lose blanket immunity under Section 230 of the Communications Decency Act, opening them up to all kinds of legal hurdles -- including civil lawsuits and criminal charges. [...] The full text of H.R.2732 is not publicly available yet, so it's unclear if anything has changed since last year's attempt, though when reintroduced last year it was more of the same. (We've reached out to the offices of Reps. Wagner and Garcia for a copy of the bill's text.) A member of Senator Graham's office confirmed to Engadget that the companion bill will be introduced within the next week. It also remains to be seen if and when this will come up for a vote. Both prior versions of EARN IT died in committee before ever coming to a vote. The Center for Internet and Society at Stanford Law School, the Center for Democracy and Technology, and the American Civil Liberties Union all oppose the bill.

Those defending it include the Rape, Abuse & Incest National Network (RAINN), saying that it will "incentivize technology companies to proactively search for and remove" CSAM materials. "Tech companies have the technology to detect, remove, and stop the distribution of child sexual abuse material. However, there is no incentive to do so because they are subject to no consequences for their inaction."

Amazon has launched its Anti-Counterfeiting Exchange (ACX), an initiative to help retail stores label and track marketplace counterfeits as part of the e-commerce giant's efforts to crack down on organized crime on its platform, the company announced on Thursday. From a report: Online marketplaces in the United States including Amazon face hurdles in keeping counterfeiters off their platforms and fake merchandise from entering their warehouses. The new program mimics data exchange programs by the credit card industry to find scammers and identify their tactics. Stores and Amazon marketplace sellers can anonymously contribute information and records flagging counterfeiters to a third-party database or use the database to avoid doing business with the bad actors.

"We think it is critical to share information about confirmed counterfeiters to help the entire industry stop these criminals earlier," Dharmesh Mehta, Amazon's vice president of selling partner services, said in a statement. The Seattle-based retail giant piloted the anti-counterfeiting initiative in 2021 with an undisclosed number of apparel, home goods and cosmetics stores, where counterfeiting is most common.

Now Australian online businesses that put up hurdles to make it harder for customers to unsubscribe from their services may face a crackdown from the federal government, with plans to be unveiled later this year. The Guardian reports: The practice of "forced continuity" or "subscription trapping" involves building design features of a website or app in a way that impedes a customer's ability to cancel a particular service. The chair of the Australian Competition and Consumer Commission (ACCC), Gina Cass-Gottlieb, said in a speech to the National Press Club on Wednesday a prohibition on unfair trade practices would help protect consumers and small businesses "exposed to manipulative practices designed to get them to agree to unfair or unfavorable contract terms".

The consumer watchdog has called for new powers in Australian consumer law to crack down on such practices since 2017. A spokesperson for the regulator said subscription traps can cause "significant harm to consumers and some small businesses." "These practices make it difficult for consumers to cancel subscriptions after fixed-term periods, with the consequence that many subscriptions roll over to paid subscriptions despite consumers no longer utilizing or wanting them," the spokesperson said. The report cites a discrepancy in the steps required to canceled an Amazon Prime subscription. In Europe, "there is a simple two-step process," reports the Guardian. "But customers in Australia must navigate four convoluted steps, with the wording and location of the cancellation button changing between each screen."

This is due to Australia's lack of unfair trading practices laws that exist in Europe and other countries.

An anonymous reader quotes a report from the Washington Post: Amazon has branded itself as a climate crusader, touting its commitment to renewable energy and sustainable practices. But in Oregon, it helped quietly quash a climate bill that would have regulated its data centers. The bill would have set a 100 percent carbon emissions reduction deadline of 2040 for high energy users. Its goal was to rein in industries with outsize carbon footprints, like cryptocurrency mines and data centers, of which Amazon is planning three more in the state that would be powered by fossil fuels. Though the bill would have matched the timeline of Amazon's own "Climate Pledge," which promises net-zero carbon emissions by 2040, the company helped kill it, said Oregon state Rep. Pam Marsh.

"Amazon's representatives were in the Capitol lobbying against the bill from the very first moment of discussion," said Marsh, chair of the Oregon House climate committee and sponsor of the bill, HB2816. Though Amazon did not testify publicly, Marsh said the company's lobbyists helped organize the opposition and "successfully nurtured fear that our energy requirements would drive away the development of data centers." "No one wants that," Marsh continued, "but we do want them to use energy in a responsible, sustainable manner."

In addition to the Climate Pledge, Amazon has set a goal of moving entirely to renewable energy by 2025; the company has spent millions on solar and wind energy projects and is the largest private purchaser of clean energy. From its $2 billion climate fund to the Climate Pledge, Amazon has invested heavily in creating the perception that it's an environmental leader. But its dealings in Oregon show that, behind the scenes, it wants to call the shots on how that transition happens. Amazon spokesperson David Ward said in a statement that "a number of organizations, including Amazon, oppose HB2816 because the bill does not address the build-out of electric infrastructure that is needed to bring more clean energy to the grid."

"Building new renewable projects requires infrastructure investments in the grid and today there are hurdles in key areas like permitting and interconnection," he continued. "Accelerating energy infrastructure permitting and interconnections for renewables like solar and wind would have a greater impact on reducing emissions, bringing more clean energy to the grid, and helping achieve our goal of accessing more clean energy in Oregon."

Oregon's biggest business organizations are all opposed to the bill, reports Government Technology. "That includes Oregon Business & Industry and the Technology Association of Oregon, and the national trade group TechNet." Aside from Amazon and its lobbying behind the scenes, no other major tech company has taken a position on the bill.

Researchers have announced a major cybersecurity find -- the world's first-known instance of real-world malware that can hijack a computer's boot process even when Secure Boot and other advanced protections are enabled and running on fully updated versions of Windows. From a report: Dubbed BlackLotus, the malware is what's known as a UEFI bootkit. These sophisticated pieces of malware hijack the UEFI -- short for Unified Extensible Firmware Interface -- the low-level and complex chain of firmware responsible for booting up virtually every modern computer. As the mechanism that bridges a PC's device firmware with its operating system, the UEFI is an OS in its own right. It's located in an SPI-connected flash storage chip soldered onto the computer motherboard, making it difficult to inspect or patch. Because the UEFI is the first thing to run when a computer is turned on, it influences the OS, security apps, and all other software that follows. These traits make the UEFI the perfect place to run malware. When successful, UEFI bootkits disable OS security mechanisms and ensure that a computer remains infected with stealthy malware that runs at the kernel mode or user mode, even after the operating system is reinstalled or a hard drive is replaced.

As appealing as it is to threat actors to install nearly invisible and unremovable malware that has kernel-level access, there are a few formidable hurdles standing in their way. One is the requirement that they first hack the device and gain administrator system rights, either by exploiting one or more vulnerabilities in the OS or apps or by tricking a user into installing trojanized software. Only after this high bar is cleared can the threat actor attempt an installation of the bootkit. The second thing standing in the way of UEFI attacks is UEFI Secure Boot, an industry-wide standard that uses cryptographic signatures to ensure that each piece of software used during startup is trusted by a computer's manufacturer. Secure Boot is designed to create a chain of trust that will prevent attackers from replacing the intended bootup firmware with malicious firmware. If a single firmware link in that chain isn't recognized, Secure Boot will prevent the device from starting.

An anonymous reader shares a report: In the decade following US President John F Kennedy's 1961 announcement of America's mission to put a man on the moon, the number of physical science PhDs tripled, and that of engineering PhDs quadrupled. Now, the country is embarking on a moonshot to rebuild the semiconductor fabrication industry. Corporations that want a cut of the $39bn in manufacturing incentives within the Chips and Science Act programme can start filing their applications for subsidies on Tuesday. In order to get them, they'll have to show that they are contributing to something that may be even more difficult than putting a man in space: building a 21st-century workforce. America has plenty of four-year graduates with crushing debt (the national average for federal loan debts is more than $37,000 a student) and underwhelming job prospects. It also has plenty of college dropouts and young people with high-school degrees who are trying to make ends meet through minimum-wage jobs supplemented by gig work.

What it lacks are the machinists, carpenters, contractors and technicians who will build the new fabrication facilities. It also needs to triple the number of college graduates in semiconductor-related fields, such as engineering, over the next decade, according to commerce secretary Gina Raimondo. Raimondo, who is well on her way to becoming the industrial strategy tsar of the administration, gave a speech to this effect earlier this month. In it, she underscored not only the need to rebuild chip manufacturing in a world in which the US and China will lead separate tech ecosystems, but also to ensure that there are enough domestic workers to do so. "If you talk to the CEOs of companies like TSMC and Samsung [both of which are launching fabs in the US], they are worried about finding these people here," Raimondo told me. She cites workforce development -- alongside scale and transparency -- as major hurdles that must be overcome to meet the administration's goals.

Genetically modified seedlings from biotechnology company Living Carbon have been planted in a low-lying tract of southern Georgia's pine belt. According to a paper that has yet to be peer reviewed, these trees are engineered to grow 50 percent faster than non-modified ones over five months in the greenhouse. The New York Times reports: The poplars may be the first genetically modified trees planted in the United States outside of a research trial or a commercial fruit orchard. Just as the introduction of the Flavr Savr tomato in 1994 introduced a new industry of genetically modified food crops, the tree planters on Monday hope to transform forestry. Living Carbon, a San Francisco-based biotechnology company that produced the poplars, intends for its trees to be a large-scale solution to climate change. "We've had people tell us it's impossible," Maddie Hall, the company's co-founder and chief executive, said of her dream to deploy genetic engineering on behalf of the climate. But she and her colleagues have also found believers -- enough to invest $36 million in the four-year-old company.

The company's researchers created the greenhouse-tested trees using a bacterium that splices foreign DNA into another organism's genome. But for the trees they planted in Georgia, they turned to an older and cruder technique known as the gene gun method, which essentially blasts foreign genes into the trees' chromosomes. In a field accustomed to glacial progress and heavy regulation, Living Carbon has moved fast and freely. The gene gun-modified poplars avoided a set of federal regulations of genetically modified organisms that can stall biotech projects for years. (Those regulations have since been revised.) By contrast, a team of scientists who genetically engineered a blight-resistant chestnut tree using the same bacterium method employed earlier by Living Carbon have been awaiting a decision since 2020. [...]

In contrast to fast-growing pines, hardwoods that grow in bottomlands like these produce wood so slowly that a landowner might get only one harvest in a lifetime, said [Vince Stanley, a seventh-generation farmer who manages more than 25,000 forested acres in Georgia's pine belt]. He hopes Living Carbon's "elite seedlings" will allow him to grow bottomland trees and make money faster. "We're taking a timber rotation of 50 to 60 years and we're cutting that in half," he said. "It's totally a win-win." [...] The U.S. Forest Service, which plants large numbers of trees every year, has said little about whether it would use engineered trees. To be considered for planting in national forests, which make up nearly a fifth of U.S. forestland, Living Carbon's trees would need to align with existing management plans that typically prioritize forest health and diversity over reducing the amount of atmospheric carbon, said Dana Nelson, a geneticist with the service. "I find it hard to imagine that it would be a good fit on a national forest," Dr. Nelson said. Living Carbon is focusing for now on private land, where it will face fewer hurdles. Later this spring it will plant poplars on abandoned coal mines in Pennsylvania. By next year Ms. Hall and Mr. Mellor hope to be putting millions of trees in the ground. The report notes that the modified trees are all female, "so they won't produce pollen."

"They're also being planted alongside native trees like sweet gum, tulip trees and bald cypress, to avoid genetically identical stands of trees known as monocultures; non-engineered poplars are being planted as experimental controls."

An anonymous reader quotes a report from CleanTechnica: Ford CEO Jim Farley made a blockbuster of a statement this week. According to the somewhat jovial and optimistic cousin of late comedic actor Chris Farley, producing electric vehicles requires about 40% less labor than producing the same number of fossil-powered cars. The fact that electric vehicles are "simpler" than internal combustion engine (ICE) vehicles has long been a talking point of electric vehicle fans and evangelists (aka EVangelists). This has mostly come into play when talking about lower maintenance costs. There aren't all the belts, tubes, hoses, etc. that you find in a gasmobile. That means fewer parts that can break and less maintenance over time. What is less discussed is what Jim Farley has highlighted this week -- that it also means simpler production and a smaller labor force manufacturing the world's cars and trucks.

Interestingly, Farley is also taking this difference to shift Ford back to more vertical integration. Rather than lay off workers, Farley aims to retrain them to produce more parts within the walls of Ford. As Farley says it, "we have to insource, so that everyone has a role in this growth." Nonetheless, that's not easy and certainly not going to be 100% smooth. Farley noted that the transition to EVs would involve "storm clouds." Recall that Ford aims to reach 50% EV sales by 2030, up from just a few percent in 2022. Making that massive transition provides the opportunity for a new approach and retraining, but also plenty of likely hurdles and challenges.

The FT highlighted that back in the days of Henry Ford, vertical integration was the name of the game. "A shift in corporate strategy towards more vertical integration at Ford would hark back to the company's early days when founder Henry Ford owned forest, iron mines, limestone quarries and even a rubber plantation in Brazil to wholly control the company's supply chain," the media outlet stated. "If Henry Ford came back to life, he would have thought the last 60 years weren't that exciting, but he would love it right now because we're totally reinventing the company," Farley said.

Ericsson subsidiary Vonage will pay $100 million to settle Federal Trade Commission allegations that it created a web of obstacles for its customers to cancel the internet-based telephone service and charged unexpected termination fees. From a report: The agreement, filed in a federal court Thursday, represents the largest settlement of its kind in the FTC's enforcement push against companies that allegedly throw up high hurdles to customers seeking to cancel subscriptions or services. New Jersey-based Vonage will be required to obtain consumers' express consent for services and simplify its cancelation process. The cost of a subscription ranged from $5 to $50 a month for consumers, and potentially thousands a month for businesses, the FTC said. The commission said it received hundreds of complaints from consumers about Vonage's tactics.

One piece of news from Tesla's AI Day presentation on Friday that was overshadowed by the company's humanoid "Optimus" robot and Dojo supercomputer was the improvements to Tesla's Full Self Driving software. According to Autopilot director Ashok Elluswamy, "there are now 160,000 customers running the beta software, compared to 2,000 from this time last year," reports The Verge. From the report: In total, Tesla says there have been 35 software releases of FSD. In a Q&A at the end of the presentation, Musk made another prediction -- he's made a few before -- that the technology would be ready for a worldwide rollout by the end of this year but acknowledged the regulatory and testing hurdles that remained before that happens. Afterward, Tesla's tech lead for Autopilot motion planning, Paril Jain, showed how FSD has improved in specific interactions and can make "human-like" decisions. For example, when a Tesla makes a left turn into an intersection, it can choose a trajectory that doesn't make close calls with obstacles like people crossing the street.

It's known that every Tesla can provide datasets to build the models that FSD uses, and according to Tesla's engineering manager Phil Duan, now Tesla will start building and processing detailed 3D structures from that data. They said the cars are also improving decision-making in different environmental situations, like night, fog, and rain. Tesla trains the company's AI software on its supercomputer, then feeds the results to customers' vehicles via over-the-air software updates. To do this, it processes video feeds from Tesla's fleet of over 1 million camera-equipped vehicles on the road today and has a simulator built in Unreal Engine that is used to improve Autopilot.

Just over two years after its launch, Facebook is shutting down the Facebook Gaming app on October 28, 2022. Now, when you open the app, you'll see a banner stating that the app will no longer be available on iOS and Android after that date. The app also won't be available on the Google Play Store or the Apple App Store. From a report: "Despite this news, our mission to connect players, fans and creators with the games they love hasn't changed, and you'll still be able to find your games, streamers and groups when you visit Gaming in the Facebook app," the notice reads. "We want to extend our heartfelt thanks to all of you for everything that you've done to build a thriving community for gamers and fans since this app first launched."

If you've been using the app, you can download your search data before the app is discontinued. The app launched in April 2020 toward the start of the COVID-19 pandemic as a way for users to watch their favorite streamers, play instant games and take part in gaming groups. Facebook experienced some hurdles trying to launch the app, as Apple rejected the app numerous times, citing its rules that prohibit apps with the main purpose of distributing casual games. Apple's rules forced Facebook to remove actual gameplay functionality from the app.

On Monday, Apple expanded its DIY repair program to include MacBook Air and MacBook Pro laptops equipped with M1 chips (including the Pro and Max). At least, in theory. The repairability experts at iFixit, who regularly dissect Apple's gadgets, have taken a look at the new program, and their outlook is...mixed. iFixit's Sam Goldheart writes that the new MacBook Pro guides "threw us for a loop." The issue: the documentation "makes MacBook Pros seem less repairable" than they have been in the past. From a report: The repair manual for replacing the 14-inch MacBook Pro's battery, for example, is a whole 162 pages long. (One of the first steps, of course, is "Read the entire manual first.") The reason the guide is so long, it turns out, is that replacing these batteries isn't just a matter of popping the battery out. A user needs to replace the entire top case and keyboard in order to replace the battery. Needless to say, it is unusual for a laptop battery replacement to require a full-computer teardown.

And then, as Goldheart points out, there's the matter of the money. The "top case with battery" part that you'll need to purchase for the 2020 and 2021 MacBook Pro models is not cheap -- after rooting around Apple's store, Verge editor Sean Hollister found that you can expect to pay well upwards of $400 for the top case with battery after the repair credit. "Apple is presenting DIY repairers with a excruciating gauntlet of hurdles: read 162 pages of documentation without getting intimidated and decide to do the repair anyway, pay an exorbitant amount of money for an overkill replacement part, decide whether you want to drop another 50 bucks on the tools they recommend, and do the repair yourself within 14 days, including completing the System Configuration to pair your part with your device," Goldheart writes in summary. "Which makes us wonder, does Apple even want better repairability?"

An anonymous reader shares this report on The Switchblade, "an aircraft that doubles as a car."

It could be "just weeks away from getting its wheels off the ground after an inspection by America's Federal Aviation Administration determined that the vehicle is safe to fly: The project has been 14 years in the making, and Sam Bousfield, CEO of Samson Sky and inventor of the Switchblade, said he's "stoked" to reach this milestone. After passing the FAA inspection, his team wasted no time in beginning the high-speed taxi test. They were out on the taxiway the next day. "[The crew] took off their 'I'm doing R&D' and they put on their 'I am flight test' crew hat, and I think that really set the tone for everything after," Bousfield said. "So, we're in a different game now...."

Just like a pocket knife, the Switchblade's wings slip smoothly into the body of the vehicle with the touch of a button, allowing it to seamlessly transition from sky to air. Its tail also unfurls or retracts, depending on if it's being used to fly or drive. The idea is that the vehicle could be parked in a garage, driven to an airport, flown to a new destination, and then driven anywhere on the ground after it lands. When a trip is over, the user can fly it home or fly it elsewhere.
"The side windows (in the doors) will be power windows," noted a tweet Thursday on the car manufacturer's official Twitter feed @FlyingSportsCar.

And Maxim points out that The Switchblade can be flown at up to 200 mph and as high as 13,000 feet, "for up to 450 miles, with the 190-hp liquid-cooled three-cylinder powering the single propeller." On the ground, the Switchblade can achieve a brisk 125 mph, making it similar to "a little flying sports car," Bousfield added.

Before production begins, the Switchblade has more regulatory hurdles that flying cars will need to overcome. Owners will need a pilot's license and either a motorcycle or driver's license to operate it in both flight and ground modes, plus car/motorcycle and aircraft insurance. But for now, the FAA flight approval has inspired Bousfield to keep charging ahead....

It will be at least a few more years before civilians are flying their own Switchblades, which are expected to cost around $170,000. But anyone can join the 1,670 people who have reserved one free of charge.

What if we glimpsed alien life for the first time by peering through a natural telescope made by the Sun's gravity? This wild idea, known as a solar gravitational lens (SGL) mission, may sound like an Einsteinian fever dream, but scientists have now found that it is "feasible with technologies that are either extant or in active development," according to a new study. Motherboard reports: Researchers led by Henry Helvajian, senior scientist in the Physical Sciences Laboratories at the nonprofit research center The Aerospace Corporation, have now shared the initial results of this ongoing NIAC study on the preprint server arxiv, which have not been peer-reviewed. Though the team cautioned that the mission would need to overcome several technical challenges, it could ultimately answer one of humanity's most fundamental questions: Are we alone in the universe?

"The SGL offers capabilities that are unmatched by any planned or conceivable optical instrument," according to the study, which was co-authored by Slava Turyshev, a scientist at NASA's Jet Propulsion Laboratory and principal investigator of the NIAC mission concept. "With its unique optical properties, the SGL can be used to obtain detailed, high resolution images of Earth-like exoplanets as far as 100 light years from Earth, with measurement durations lasting months, or at most a few years." "Of particular interest is the possibility of using the SGL to obtain images of high spatial and spectral resolution of a yet-to-be-identified, potentially life-bearing exoplanet in another solar system in our Galactic neighborhood," the researchers added. "The direct high-resolution images of an exoplanet obtained with the SGL could lead to insight on the on-going biological processes on the target exoplanet and find signs of habitability."

The focal point of the Sun's gravitational lens is located all the way out in interstellar space, some 550 and 900 times the distance that Earth orbits our star, which is much farther than any spacecraft has ventured beyond our planet. Helvajian and his colleagues envision their mission as consisting of a one-meter telescope that is accompanied by a sunshade and propelled by solar sails that produce thrust by capturing solar radiation, in a somewhat analogous fashion to wind-propelled sails. Even if they were able to overcome the technical hurdles involved with this concept -- which include the development of more reliable solar sails and long-duration navigation and communications systems -- the team estimated that it would take at least 25 to 30 years for a spacecraft to reach this far-flung location, in the best case scenario. That said, if a telescope were able to spot alien life, arguably the biggest breakthrough in science, it would be well worth the long wait.

Volvo Trucks said Monday that it had begun to test vehicles that use "fuel cells powered by hydrogen," with the Swedish firm claiming their range could extend to as much as 1,000 kilometers, or a little over 621 miles. CNBC reports: In a statement, Gothenburg-headquartered Volvo Trucks said refueling of the vehicles would take under 15 minutes. Customer pilots are set to begin in the next few years, with commercialization "planned for the latter part of this decade." Fuel cells for the vehicles will be provided by cellcentric, a joint venture with Daimler Truck that was established in March 2021. Alongside hydrogen fuel cell vehicles, Volvo Trucks -- which is part of the Volvo Group -- has also developed battery-electric trucks. [...] While there is excitement in some quarters about the potential of hydrogen-powered vehicles, there are hurdles when it comes to expanding the sector, a point acknowledged by Volvo Trucks on Monday. It pointed to challenges including the "large-scale supply of green hydrogen" as well as "the fact that refueling infrastructure for heavy vehicles is yet to be developed."

Described by the IEA as a "versatile energy carrier," hydrogen has a diverse range of applications and can be deployed in a wide range of industries. It can be produced in a number of ways. One method includes using electrolysis, with an electric current splitting water into oxygen and hydrogen. If the electricity used in this process comes from a renewable source such as wind or solar then some call it "green" or "renewable" hydrogen. Today, the vast majority of hydrogen generation is based on fossil fuels. Last week, Volvo Construction Equipment, which is also part of the Volvo Group, said it had commenced testing of a "fuel cell articulated hauler prototype."

An anonymous reader quotes a report from Interesting Engineering: [T]he world is now one step closer to seeing operational space-based solar energy as scientists from China's Xidian University completed testing and inspection on a ground array built to collect space-based solar power. They conducted a successful test of the "world's first full-link and full-system solar power plant" on June 5, according to a press statement from the university. The space-based solar power plant is a 246-feet-tall (75 meters) steel tower built on Xidian University's southern campus.

In theory, the Xidian University power plant will connect to orbital satellites that will harvest solar power 24/7 due to their geostationary orbits, before beaming that energy down to Earth via high-frequency microwave beams. The power plant will feature five different subsystems aimed at developing space-based solar power arrays. Space-based solar power has great potential as it can collect energy continuously while sidestepping common problems such as bad weather and waiting for daybreak. However, hurdles do remain, such as assessing the effects of a high-frequency energy beam on communications, air traffic, and the well-being of nearby residents.

Xidian University's new ground station is part of a space-based solar power proposal called OMEGA, which stands for Orb-Shape Membrane Energy Gathering Array. The project was first proposed in 2014 by Duan Baoyan from the Xidian University School of Electromechanical Engineering and his colleagues. [...] China's OMEGA project, meanwhile, has successfully transmitted energy wirelessly as microwaves over a distance of approximately 180 feet (55 meters). This capability puts the project three years ahead of its original schedule, the university says in its press release. Still, Baoyan concedes that a lot of work is still required, and fully operational space-based solar power could still be years away.

The US defence contractor L3Harris is in talks to take over NSO Group's surveillance technology, in a possible deal that would give an American company control over one of the world's most sophisticated and controversial hacking tools. From a report: Multiple sources confirmed that discussions were centred on a sale of the Israeli company's core technology â" or code â" as well as a possible transfer of NSO personnel to L3Harris. But any agreement still faces significant hurdles, including requiring the blessing of the US and Israeli governments, which have not yet given the green light to a deal. In a statement, a senior White House official said: "Such a transaction, if it were to take place, raises serious counterintelligence and security concerns for the US government." If agreed, the deal would mark an astounding turnaround for NSO, less than a year after the Biden administration placed the company on a US blacklist and accused it of acting "contrary to the foreign policy and national security interests of the US."

There is enough energy in the nuclear waste in the United States to power the entire country for 100 years with clean energy, says Jess C. Gehin at the Idaho National Laboratory. CNBC reports: There are 93 commercial nuclear reactors at 55 operating sites in the United States, according to Scott Burnell, spokesperson for the Nuclear Regulatory Commission. Twenty-six are in some stage of decommissioning process. All of the nuclear reactors that operate in the U.S. are light-water reactor designs [...]. In a light-water reactor, uranium-235 fuel powers a fission reaction, where the nucleus of an atom splits into smaller nuclei and releases energy. The energy heats water, creating steam which is used to power a generator and produce electricity. The nuclear fission reaction leaves waste, which is radioactive and has to be maintained carefully. There are about 80,000 metric tons of used fuel from light-water nuclear reactors in the United States and the existing nuclear fleet produces approximately an additional 2,000 tons of used fuel each year, Gehin told CNBC. But after a light-water reactor has run its reactor powered by uranium-235, there is still tremendous amount of energy potential still available in what is left.

"Fundamentally, in light-water reactors, out of the uranium we dig out of the ground, we use a half a percent of the energy that's in the uranium that's dug out of the ground," Gehin told CNBC in a phone interview. "You can get a large fraction of that energy if you were to recycle the fuel through fast reactors." Fast reactors don't slow down the neutrons that are released in the fission reaction, and faster neutrons beget more efficient fission reactions, Gehin told CNBC. "Fast neutron reactors can more effectively convert uranium-238, which is predominantly what's in spent fuel, to plutonium, so you can fission it," Gehin said.

Even as private companies are working to innovate and commercialize fast reactor designs, there are significant infrastructure hurdles. Before nuclear waste can be used to power fast reactors, it has to go through reprocessing. Right now, only Russia has the capacity to do this at scale. France, too, has the capacity to recycle used nuclear waste, Gehin said, but the country generally takes its recycled fuel and puts it back into existing light water reactors. For now, the Idaho National Lab can reprocess enough fuel for research and development, Gehin told CNBC, but not much more.

Private companies commercializing fast reactor technology are pushing for domestic fuel supply chains to be developed. TerraPower says it's investing in supply chains and working with elected leaders to build political support, while Oklo has received three government awards and is working with the government to commercialize fast reactor fuel supply chains domestically. The other option to power fast reactors is to create HALEU fuel, which stands for high-assay low-enriched uranium, from scratch, rather than by recycling nuclear waste. (Where conventional reactors use uranium enriched up to 5%, HALEU is uranium enriched up to 20%.) It's arguably easier to produce HALEU directly than by recycling spent waste, says Gehin, but ultimately, the cheaper option will win out. "It will be largely be driven by what makes sense economically." Regardless, Russia is the only country that has the capacity to make HALEU at commercial scale.

Playdate, the hotly anticipated video game system from Portland tech company Panic, began shipping Monday after a succession of manufacturing setbacks delayed the gadget by more than two years. OregonLive reports: Playdate is a throwback to the handheld video games of the 1980s. Designers eschewed the latest graphics technology in favor of a simple, black-and-white screen and an old-fashioned directional button pad. In a note of whimsey, the $179 Playdate also has a crank on the side. The crank provides various functions across the 24 games that come with purchase. (Games will be released online, two at a time, over the next 12 weeks.)

Panic is a software company, not an electronics manufacturer, and its first foray into computer hardware encountered a string of problems -- exacerbated by the pandemic and the resulting global shortage in computer chips. Most recently, Panic announced last November that many of its first 5,000 Playdates had faulty batteries. The company responded by sending them all back to its manufacturing contractor in Malaysia for replacement with new batteries from a different supplier.

Playdate fielded 20,000 orders in just 20 minutes when the first gadgets went on sale last July. And despite the delays, initial reviews Monday were very enthusiastic [...]. All the reviews noted, though, that Panic is a long way from untangling its production snarls. Only the first orders are going out now -- thousands more Playdates are coming sometime later, though Panic hasn't said just when. There's also good news for DIYers: iFixit's teardown says the gaming system is relatively easy to fix if you ever need to replace its battery or buttons.
