Free Bi-Directional EV Chargers Tested to Improve Massachusetts Power Grid

2026年2月8日 01:34

🤖 AI Summary

マサチューセッツ州の経済開発機関 **MassCEC** が、住民・学区・自治体を対象に「無料」の双方向(V2X)電気自動車充電器を提供する実証プログラムを開始した。
- 充電だけでなく、車両から電力を逆送できるため、停電時のバックアップ電源やピーク時の需要削減に活用できる。
- 需要応答イベントで 1 MW 超の電力を電網に供給でき、約 300 戸分の電力を 1 時間分まかなえる規模。
- 参加者は既存のユーティリティの“電力供給報酬”プログラムにも加入でき、電気代のさらなる削減が期待できる。
- バーチャル・パワー・プラント(VPP)として分散エネルギー資源を活用し、州全体の電力インフラ負荷軽減とクリーンエネルギー技術の普及を狙う。

この取り組みにより、マサチューセッツは全国的なクリーンエネルギーイノベーションのリーダーとして位置付けられる。
Somewhere on America's eastern coast, there's an economic development agency in Massachusetts promoting green energy solutions. And Monday the Massachusetts Clean Energy Center (or MassCEC) announced "a first-of-its-kind" program to see what happens when they provide free electric vehicle chargers to selected residents, school districts, and municipal projects. The catch? The EV chargers are bi-directional, able "to both draw power from and return power to the grid..." The program hopes to "accelerate the adoption of V2X technologies, which, at scale, can lower energy bills by reducing energy demand during expensive peak periods and limiting the need for new grid infrastructure." This functionality enables EVs, including electric buses and trucks, to provide backup power during outages and alleviate pressure on the grid during peak energy demand. These bi-directional chargers will enable EVs to act as mobile energy storage assets, with the program expected to deliver over one megawatt of power back to the grid during a demand response event — enough to offset the electricity use of 300 average American homes for an hour. "Virtual Power Plants are the future of our electrical grid, and I couldn't be more excited to see this program take off," said Energy and Environmental Affairs Secretary Rebecca Tepper. "We're putting the power of innovation directly in the hands of Massachusetts residents. Bi-directional charging unlocks new ways to protect communities from outages and lower costs for families and public fleets...." Additionally, the program will help participants enroll in existing utility programs that offer compensation to EV owners who supply power back to the grid during peak times, helping participants further lower their electricity costs. By leveraging distributed energy resources and reducing grid strain, this program positions Massachusetts as a national leader in clean energy innovation.

Japanese Volunteer Translators Quit After Mozilla Begins Using Translation Bot

2025年11月9日 02:34
Long-time Slashdot reader AmiMoJo shared this report from Linuxiac: The Japanese branch of Mozilla's Support Mozilla (SUMO) community — responsible for localizing and maintaining Japanese-language support documentation for Firefox and other Mozilla products (consisting of Japanese native speakers) — has officially disbanded after more than two decades of voluntary work... SUMO, short for Support Mozilla, is the umbrella project for Mozilla's user support platform, support.mozilla.org, that brings together volunteers and contributors worldwide who translate, maintain, and update documentation, tutorials, and troubleshooting guides for Firefox, Thunderbird, and other Mozilla products... According to marsf, the long-time locale leader of the Japanese SUMO team, the decision to disband was triggered by the recent introduction of an automated translation system known as Sumobot. Deployed on October 22, the bot began editing and approving Japanese Knowledge Base articles without community oversight. The article notes marsf's complaints in a post to the SUMO discussion forum, including the fact that the new automated system automatically approved machine-translated content with only a 72-hour window for human review. As a result, more than 300 Knowledge Base articles were overwritten on the production server, which marsf called "mass destruction of our work."

Why the Internet Archive is More Relevant Than Ever

2025年3月24日 20:34
It's "live-recording the World Wide Web," according to NPR, with a digital library that includes "hundreds of billions of copies of government websites, news articles and data." They described the 29-year-old nonprofit Internet Archive as "more relevant than ever." Every day, about 100 terabytes of material are uploaded to the Internet Archive, or about a billion URLs, with the assistance of automated crawlers. Most of that ends up in the Wayback Machine, while the rest is digitized analog media — books, television, radio, academic papers — scanned and stored on servers. As one of the few large-scale archivists to back up the web, the Internet Archive finds itself in a particularly unique position right now... Thousands of [U.S. government] datasets were wiped — mostly at agencies focused on science and the environment — in the days following Trump's return to the White House... The Internet Archive is among the few efforts that exist to catch the stuff that falls through the digital cracks, while also making that information accessible to the public. Six weeks into the new administration, Wayback Machine director [Mark] Graham said, the Internet Archive had cataloged some 73,000 web pages that had existed on U.S. government websites that were expunged after Trump's inauguration... According to Graham, based on the big jump in page views he's observed over the past two months, the Internet Archive is drawing many more visitors than usual to its services — journalists, researchers and other inquiring minds. Some want to consult the archive for information lost or changed in the purge, while others aim to contribute to the archival process.... "People are coming and rallying behind us," said Brewster Kahle, [the founder and current director of the Internet Archive], "by using it, by pointing at things, helping organize things, by submitting content to be archived — data sets that are under threat or have been taken down...." A behemoth of link rot repair, the Internet Archive rescues a daily average of 10,000 dead links that appear on Wikipedia pages. In total, it's fixed more than 23 million rotten links on Wikipedia alone, according to the organization. Though it receives some money for its preservation work for libraries, museums, and other organizations, it's also funded by donations. "From the beginning, it was important for the Internet Archive to be a nonprofit, because it was working for the people," explains founder Brewster Kahle on its donations page: Its motives had to be transparent; it had to last a long time. That's why we don't charge for access, sell user data, or run ads, even while we offer free resources to citizens everywhere. We rely on the generosity of individuals like you to pay for servers, staff, and preservation projects. If you can't imagine a future without the Internet Archive, please consider supporting our work. We promise to put your donation to good use as we continue to store over 99 petabytes of data, including 625 billion webpages, 38 million texts, and 14 million audio recordings. Two interesting statistics from NPR's article: "A Pew Research Center study published last year found that roughly 38% of web pages on the internet that existed in 2013 were no longer accessible as of 2023." "According to a Harvard Law Review study published in 2014, about half of all links cited in U.S. Supreme Court opinions no longer led to the original source material."

Internet Archive Celebrates New Public Domain Works with Remixes in Short Film Contest

2025年2月9日 01:34
To celebrate 2025's newest arrivals in the public domain, the Internet Archive held a special in-person event at their San Francisco headquarters, as well as a virtual celebration online. (It opens with an absolutely gorgeous rendition of "Happy Days are Hear Again" played on a musical saw.) And somewhere in the festivities they announced the winners of this year's annual "Public Domain Day Film Remix Contest." These remarkable films not only reimagined and transformed public domain works but also demonstrated the boundless potential of remixing creative works to create something new... Explore all 140+ submissions at the 2025 Public Domain Day Film Remix Contest collection at the Internet Archive... "The jury was deeply impressed by Queline Meadows's inspired mix of movies, images, music and text woven into a subtle and emotionally affecting video expressing a strong sense of nostalgia and the irretrievable passage of time," said film archivist Rick Prelinger... Filmmaker Samantha Close expresses both the breadth of 1929's production and the eternal bounty of the public domain, using images from 1929's films and public domain images from elsewhere and elsewhen. One honorable mention entry was described as "an audacious and yes, dopey exploration of the essential greatness of Internet Archive and the dread near-infinity of copyright."

Can Heat Pumps Still Save the Planet from Climate Change?

2024年11月4日 00:34
"One technology critical to fighting climate change is lagging," reports the Washington Post, "thanks to a combination of high interest rates, rising costs, misinformation and the cycle of home construction. Adoption of heat pumps, one of the primary ways to cut emissions from buildings, has slowed in the United States and stalled in Europe, endangering the switch to clean energy. "Heat pump investment in the United States has dropped by 4 percent in the past two years, even as sales of EVs have almost doubled, according to data from MIT and the Rhodium Group. In 13 European countries, heat pump sales dropped nearly in half in the first half of 2024, putting the European Union off-track for its climate goals." "Many many markets are falling," said Paul Kenny, the director general of the European Heat Pump Association. "It takes time to change people's minds about a heating system." Heat pumps — essentially air conditioners that can also work in reverse, heating a space as well as cooling it — are crucial to making buildings more climate-friendly. Around 60 percent of American homes are still heated with furnaces running on oil, natural gas, or even propane; to cut emissions from homes, all American houses and apartments will need to be powered by electricity... In the United States, experts point to lags in construction, high interest rates, and general belt-tightening from inflation... [Cora Wyent, director of research for the electrification advocacy group Rewiring America] added, heat pumps are still growing as a share of overall heating systems, gaining ground on gas furnaces. In 2023, heat pumps made up 55 percent of all heating systems sold, while gas furnaces made up just 45 percent. "Heat pumps are continuing to increase their total market share," she said. Homeowners may also run into trouble when trying to find contractors to install heat pumps. Barton James, the president and CEO of the Air Conditioning Contractors of America, says many contractors don't have training on how to properly install heat pumps; if they install them incorrectly, the ensuing problems can sour consumers on the technology... In the United States, low gas prices also make the economics of heat pumps more challenging. Gas is around three times cheaper than electricity — while heat pumps make up most of that ground with efficiency, they aren't the most cost-effective option for every household. The Post also spoke to the manager for the carbon-free buildings team at the clean energy think tank RMI. They pointed out that heating systems need to be replaced roughly every 15 years — and the next cycle doesn't start until 2035. The article concludes that "even with government policies and subsidies, many parts of the move to clean energy will require individual people to make changes to their lives. According to the International Energy Agency, the number of heat pumps will have to triple by 2030 to stay on track with climate goals. The only way to do that, experts say, is if incentives, personal beliefs, and technology all align."

Internet Archive Users Start Receiving Email From 'Some Random Guy' Criticizing Unpatched Hole

2024年10月21日 02:35
A post shared Saturday on social media acknowledges those admins and developers at the Internet Archive working "literally round the clock... They have taken no days off this past week. They are taking none this weekend... they are working with all of their energy and considerable talent." It describes people "working so incredibly hard... putting their all in," with a top priority of "getting the site back secure and safe". But there's new and continuing problems, reports The Verge's weekend editor: Early this morning, I received an email from "The Internet Archive Team," replying to a message I'd sent on October 9th. Except its author doesn't seem to have been the digital archivists' support team — it was apparently written by the hackers who breached the site earlier this month and who evidently maintain some level of access to its systems. I'm not alone. Users on the Internet Archive subreddit are reporting getting the replies, as well. Here is the message I received: It's dispiriting to see that even after being made aware of the breach 2 weeks ago, IA has still not done the due diligence of rotating many of the API keys that were exposed in their gitlab secrets. As demonstrated by this message, this includes a Zendesk token with perms to access 800K+ support tickets sent to [email protected] since 2018. Whether you were trying to ask a general question, or requesting the removal of your site from the Wayback Machine — your data is now in the hands of some random guy. If not me, it'd be someone else. The site BleepingComputer believes they know the larger context, starting with the fact that they've also "received numerous messages from people who received replies to their old Internet Archive removal requests... The email headers in these emails also pass all DKIM, DMARC, and SPF authentication checks, proving they were sent by an authorized Zendesk server." BleepingComputer also writes that they'd "repeatedly tried to warn the Internet Archive that their source code was stolen through a GitLab authentication token that was exposed online for almost two years." And that "the threat actor behind the actual data breach, who contacted BleepingComputer through an intermediary to claim credit for the attack," has been frustrated by misreporting. (Specifically, they insist there were two separate attacks last week — a DDoS attack and a separate data breach for a 6.4-gigabyte database which includes email addresses for the site's 33 million users.) The threat actor told BleepingComputer that the initial breach of Internet Archive started with them finding an exposed GitLab configuration file on one of the organization's development servers, services-hls.dev.archive.org. BleepingComputer was able to confirm that this token has been exposed since at least December 2022, with it rotating multiple times since then. The threat actor says this GitLab configuration file contained an authentication token allowing them to download the Internet Archive source code. The hacker say that this source code contained additional credentials and authentication tokens, including the credentials to Internet Archive's database management system. This allowed the threat actor to download the organization's user database, further source code, and modify the site. The threat actor claimed to have stolen 7TB of data from the Internet Archive but would not share any samples as proof. However, now we know that the stolen data also included the API access tokens for Internet Archive's Zendesk support system. BleepingComputer attempted contact the Internet Archive numerous times, as recently as on Friday, offering to share what we knew about how the breach occurred and why it was done, but we never received a response. "The Internet Archive was not breached for political or monetary reasons," they conclude, "but simply because the threat actor could... "While no one has publicly claimed this breach, BleepingComputer was told it was done while the threat actor was in a group chat with others, with many receiving some of the stolen data. This database is now likely being traded amongst other people in the data breach community, and we will likely see it leaked for free in the future on hacking forums like Breached."

Can Japan's H2-A Rocket Deliver a Precision-Lander to the Moon?

2023年9月10日 05:39
The Washington Post reports: Japan launched a lunar mission Thursday, overcoming multiple failures and delays to become the fifth country to head to the moon — just weeks after India — in a global race to better understand Earth's closest neighbor... It is scheduled to enter the moon's orbit in three to four months and land early next year. The rocket is carrying two space missions: a new X-ray telescope to help scientists better understand the origins of the universe and a lightweight high-precision moon lander that will serve as the basis for future moon landing technology. The telescope separated at 8:56 a.m., and the moon lander separated at 9:29 a.m... Japan has made several attempts to reach the moon, including its Omotenashi project to land an ultrasmall probe. In November, Japan abandoned the project after failing to restore communications with the spacecraft. Earlier this year, Tokyo-based space company ispace also pulled the plug on the first Japanese private-sector attempt to land on the moon. Japan's high-precision lander hopes to land within 328 feet (100 meters) of its target — which the article says it "much closer than conventional lunar landers, which usually have an accuracy of several kilometers."

The Orange Pi 5: a Fast Alternative To The Raspberry Pi 4

2023年3月26日 23:34
"With an 8-core Rockchip RK3588S SoC, the Orange Pi 5 is leaps and bounds faster than the aging Raspberry Pi 4," writes Phoronix: With up to 32GB of RAM, the Orange Pi 5 is also capable of serving for a more diverse user-base and even has enough potential for assembling a budget Arm Linux developer desktop. I've been testing out the Orange Pi 5 the past few weeks and it's quite fast and nice for its low price point. The Orange Pi 5 single board computer was announced last year and went up for pre-ordering at the end of 2022.... When it comes to the software support, among the officially available options for the Orange Pi 5 are Orange Pi OS, Ubuntu, Debian, Android, and Armbian. Other ARM Linux distributions will surely see varying levels of support while even the readily available ISO selection offered by Orange Pi is off to a great start.... Granted, the Orange Pi developer community isn't as large as that of the Raspberry Pi community or the current range of accessories and documentation, but for those more concerned about features and performance, the Orange Pi 5 is extremely interesting. The article includes Orange Pi 5 specs: A 26-pin headerHDMI 2.1, Gigabit LAN, M.2 PCIe 2.0, and USB3 connectivityA Mali G510 MP4 graphics processor, "which has open-source driver hope via the Panfrost driver stack."Four different versions with 4GB, 8GB, 16GB, or 32GB of RAM using LPDDR4 or LPDDR4X. "The Orange Pi 4GB retails for ~$88, the Orange Pi 5 8GB version retails for $108, and the Orange Pi 5 16GB version retails for $138, while as of writing the 32GB version wasn't in stock." In 169 performance benchmarks (compared to Raspberry Pi 4 boards), "this single board computer came out to delivering 2.85x the performance of the Raspberry Pi 400 overall." And through all this the average SoC temperature was 71 degrees with a peak of 85 degrees — without any extra heatsink or cooling.

Internet Archive Loses in Court. Judge Rules They Can't Scan and Lend eBooks

2023年3月26日 01:34
The Verge reports: A federal judge has ruled against the Internet Archive in Hachette v. Internet Archive, a lawsuit brought against it by four book publishers, deciding that the website does not have the right to scan books and lend them out like a library. Judge John G. Koeltl decided that the Internet Archive had done nothing more than create "derivative works," and so would have needed authorization from the books' copyright holders — the publishers — before lending them out through its National Emergency Library program. The Internet Archive says it will appeal. The decision was "a blow to all libraries and the communities we serve," argued Chris Freeland, the director of Open Libraries at the Internet Archive. In a blog post he argued the decision "impacts libraries across the U.S. who rely on controlled digital lending to connect their patrons with books online. It hurts authors by saying that unfair licensing models are the only way their books can be read online. And it holds back access to information in the digital age, harming all readers, everywhere. The Verge adds that the judge rejected "fair use" arguments which had previously protected a 2014 digital book preservation project by Google Books and HathiTrust: Koetl wrote that any "alleged benefits" from the Internet Archive's library "cannot outweigh the market harm to the publishers," declaring that "there is nothing transformative about [Internet Archive's] copying and unauthorized lending," and that copying these books doesn't provide "criticism, commentary, or information about them." He notes that the Google Books use was found "transformative" because it created a searchable database instead of simply publishing copies of books on the internet. Koetl also dismissed arguments that the Internet Archive might theoretically have helped publishers sell more copies of their books, saying there was no direct evidence, and that it was "irrelevant" that the Internet Archive had purchased its own copies of the books before making copies for its online audience. According to data obtained during the trial, the Internet Archive currently hosts around 70,000 e-book "borrows" a day. Thanks to long-time Slashdot reader esme for sharing the news.

Anonymous Launches Attacks Against Russia and Pledges Support For Ukraine

2022年2月27日 03:34
A long-time Slashdot reader shares this report Friday from the Independent: Hacking group Anonymous has said that it will support Ukraine in its fight against Russia, and has already claimed an attack on the state-controlled TV network Russia Today.... While the fight on the ground was happening, Russia Today's servers were taken offline. The broadcaster has been criticised for putting out "propaganda" to the extent that the UK government has asked media regulator Ofcom to review its output. Anonymous claimed credit for the attack, posting on Twitter that it took down the "propaganda station... in response to Kremlin's brutal invasion". The group did not respond to The Independent's request for comment. At the time of the tweet RT was briefly unavailable, before returning online without images. Currently, the broadcaster is online and appears to be operating as normal. "After the statement by Anonymous, RT's websites became the subject of a massive DDoS attack from nearly 100 million devices, mostly based in the US", RT told The Independent in a statement. "Due to the hack there were temporary website access limitations for some users, yet RT promptly resolved these issues...." Due to the nature of the Anonymous group, it can sometimes be difficult to verify their attacks as anyone can claim to be a member of the community without revealing their identity. Early Friday morning Anonymous also tweeted that "The Russian Ministry of Defense website is down."

DuckDuckGo Search Queries Grew 47% in 2021

2021年12月27日 08:59
"The privacy-focused search engine DuckDuckGo continues to grow rapidly, with the company now averaging over 100 million daily search queries and growing by almost 47% in 2021..." reports BleepingComputer: In 2020, DuckDuckGo received 23.6 billion total search queries and achieved a daily average of 79 million search queries by the end of December. In 2021, DuckDuckGo received 34.6 billion total search queries so far and currently has an average of 100 million search queries per day, showing a 46.4% growth for the year. While DuckDuckGo's growth is considerable, it still only has 2.53% of the total market share, with Yahoo at 3.3%, Bing at 6.43%, and Google holding a dominant share of 87.33% of search engine traffic in the USA. However, as people continue to become frustrated with how their data is being used by tech giants like Google, Facebook, Microsoft, and Apple, we will likely see more people switch to privacy-focused search engines. This year DuckDuckGo also released their own email forwarding service, and announced work on the DuckDuckGo Privacy Browser for Desktop — which will be built from scratch and not be based on Chromium.

YouTube Blocks 31st Ig Nobel Awards Ceremony, Citing Copyright on a Recording from 1914

2021年9月20日 00:34
The 31st annual Ig Nobel Prizes were awarded at a special ceremony on September 9th, announced the magazine responsible for the event, the Annals of Improbable Research. But this week they made another announcement. "YouTube's notorious takedown algorithms are blocking the video of the 2021 Ig Nobel Prize ceremony." We have so far been unable to find a human at YouTube who can fix that. We recommend that you watch the identical recording on Vimeo. Here's what triggered this: The ceremony includes bits of a recording (of tenor John McCormack singing "Funiculi, Funicula") made in the year 1914. YouTube's takedown algorithm claims that the following corporations all own the copyright to that audio recording that was MADE IN THE YEAR 1914: "SME, INgrooves (on behalf of Emerald); Wise Music Group, BMG Rights Management (US), LLC, UMPG Publishing, PEDL, Kobalt Music Publishing, Warner Chappell, Sony ATV Publishing, and 1 Music Rights Societies"

Mozilla Experiment: Set Default Search Engine to Bing for 1% of Firefox Users

2021年9月19日 05:34
"Mozilla is running an experiment on 1% of the Firefox desktop population currently, which sets the default search engine to Bing in the web browser," reports Ghacks: [I]n most regions, it is Google Search. Mozilla and Google extended the search deal in 2020 for another three years. Google is paying Mozilla "between $400 and $450 million per year" so that its search engine is the default in Firefox in most regions. Google has been Firefox's default search engine since 2017, when Mozilla ended its search deal with Yahoo early. Firefox users may change the default search engine to one of the other engines that are included by default, or an engine that is not included but can be added... The study started on September 6 and it will run until early 2022, likely January 2022. About 1% of Firefox desktop users may notice that the default search engine is changed when the installation of Firefox is picked for the experiment. Tip: load about:studies in the Firefox address bar to list the studies that the browser us currently taking part in and has completed already. Firefox users who don't want to participate in studies can disable the preference "Allow Firefox to install and run studies" on about:preferences#privacy.

NASA Struggles to Fix Failure of Hubble Space Telescope's 1980s Computer

2021年6月21日 00:34
The Hubble Space Telescope was launched into low-earth orbit in 1990 with an even older computer. Over the next 13 years it received upgrades and repairs from astronauts on five different visits from America's Space Shuttle. But now in 2021, "NASA continues to work on resolving an issue with the payload computer on the Hubble Space Telescope," reports SciTechDaily — though "The telescope itself and science instruments remain in good health." The operations team will be running tests and collecting more information on the system to further isolate the problem. The science instruments will remain in a safe mode state until the issue is resolved... The computer halted on Sunday, June 13. An attempt to restart the computer failed on Monday, June 14. Initial indications pointed to a degrading computer memory module as the source of the computer halt. When the operations team attempted to switch to a back-up memory module, however, the command to initiate the backup module failed to complete. Another attempt was conducted on both modules Thursday evening to obtain more diagnostic information while again trying to bring those memory modules online. However, those attempts were not successful.

Japan Poised to Approve Release of Fukushima Nuclear Plant Water Into the Ocean

2021年4月11日 00:34
New submitter evaverdeazul shared this report from Japan Today: The Japanese government is poised to release treated radioactive water accumulated at the crippled Fukushima nuclear plant into the sea despite opposition from fishermen, sources familiar with the matter said Friday. It will hold a meeting of related ministers as early as Tuesday to formally decide on the plan, a major development following over seven years of discussions on how to discharge the water used to cool down melted fuel at the Fukushima Daiichi plant. The treated water containing radioactive tritium, a byproduct of nuclear reactors, is said to pose little risk to human health because even if one drinks the water, so long as the tritium concentration is low, the amounts of tritium would not accumulate in the body and would soon be excreted. There is also no risk of external exposure even if the water comes in contact with skin. Still, concerns remain among Japan's fisheries industry and consumers as well as neighboring countries such as South Korea and China. The government has said it cannot continue postponing a decision on the disposal issue, given that the storage capacity of water tanks at the Fukushima complex is expected to run out as early as fall next year. It asserts that space needs to be secured on the premises, such as for keeping melted fuel debris that will be extracted from the damaged reactors, to move forward with the decades-long process of scrapping the complex. Plant operator Tokyo Electric Power Company Holdings Inc (TEPCO) says it will take around two years for the discharge to start.

SpaceX Launches a Falcon 9 Rocket Carrying a Crew Dragon Capsule With Four Astronauts

2020年11月16日 09:25
The big launch finally happens in 2 minutes. "All systems are go for tonight's launch at 7:27 p.m. EST of Crew Dragon's first operational mission with four astronauts on board," SpaceX tweeted this morning. But live coverage is already streaming on SpaceX's web site. Space.com explains it's the first operational flight of SpaceX's "astronaut taxi," the Crew Dragon: Called Crew-1, this will be the second Crew Dragon mission to carry astronauts. NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker, along with Japan Aerospace Exploration Agency astronaut Soichi Noguchi, will lift off from the historic Launch Complex 39A at NASA's Kennedy Space Center in Florida at 7:27p.m. EST (0027 GMT) to begin a six-month mission. Space.com reports that the astronauts completed their 9-mile (14 km) drive to the Falcon 9 rocket on the launch pad inside a pair of Tesla's electric Model X SUVs. In another report, CBS News has confirmed that SpaceX "plans to reuse the booster for the next Crew Dragon flight." NASA is counting on the Crew-1 flight and follow-on missions by SpaceX and Boeing to end the agency's sole reliance on Russian Soyuz spacecraft for trips to and from low-Earth orbit. NASA has spent $4 billion since 2006 buying seats aboard Soyuz spacecraft and another $6 billion to date on its Commercial Crew Program, ultimately awarding contracts to SpaceX and Boeing... With two successful test flights behind them, NASA engineers were able to certify the spacecraft after a detailed analysis of telemetry and inspections of the flight hardware. It was the first such certification since the space shuttle was being built in the 1970s and the first ever granted a commercially developed spacecraft. "I believe 20 years from now, we're going to look back at this time as a major turning point in our exploration and utilization of space," said Phil McAlister, director of commercial spaceflight development at NASA Headquarters. "It's not an exaggeration to state that with this milestone, NASA and SpaceX have changed the historical arc of human space transportation... The station's life support systems, including its water recycling equipment and carbon dioxide removal gear, have been beefed up to support a seven-member crew and additional stores and supplies have been laid in. But the U.S. segment of the station only has four crew "sleep stations" and Hopkins plans to bunk with a sleeping bag in the powered-down Crew Dragon.

Japan's NTT Docomo Admits Thieves Breeched Its e-Money Service

2020年9月14日 00:34
Long-time Slashdot reader PuceBaboon tipped us off to a story in Japan Times: About 18 million yen ($169,563) has been stolen from bank accounts linked to NTT Docomo Inc.'s e-money service, the company said Thursday, prompting police to begin an investigation into a suspected scam. As of Thursday, 66 cases of improper withdrawals from bank accounts linked to the mobile carrier's e-money service had been confirmed, NTT Docomo Vice President Seiji Maruyama told a news conference in Tokyo. "We apologize to the victims" of the improper withdrawals, Maruyama said at the news conference, which was also attended by other company executives. Maruyama acknowledged that checks on user identification had been "insufficient." NTT Docomo, which has stopped allowing customers to create new links between its e-money service and accounts at 35 partner banks, has said it will try to compensate victims for the full amounts stolen through negotiations with the banks.... In May last year, there were similar cases of improper withdrawals from Resona Bank accounts linked to NTT Docomo's e-money service. Docomo acknowledged it had failed to boost user identity checks to prevent a recurrence... In the recent cases, third parties are believed to have obtained the victims' bank account numbers and passwords, and used them to register with the e-money service to transfer funds.

Will Japan Have Flying Taxis by 2023?

2020年9月13日 07:34
Slashdot reader damitr shared IEEE Spectrum's look at Japan's push for flying taxi services: Last year, Spectrum reported on Japan's public-private initiative to create a new industry around electric vertical takeoff and landing vehicles and flying cars. Last Friday [August 28th], start-up company SkyDrive Inc. demonstrated the progress made since then when it held a press conference to spotlight its prototype vehicle and show reporters a video taken three days earlier of the craft undergoing a piloted test flight in front of staff and investors... In May, SkyDrive unveiled a drone for commercial use that is based on the same drive and power systems as the SD-03. Named the Cargo Drone, it's able to transport payloads of up to 30 kg and can be preprogrammed to fly autonomously or be piloted manually. It will be operated as a service by SkyDrive, starting at a minimum monthly rental charge of 380,000 yen ($3,600) that rises according to the purpose and frequency of use.... Tomohiro Fukuzawa, SkyDrive's CEO, established SkyDrive in 2018 after leaving Toyota Motor and working with Cartivator, a group of volunteer engineers interested in developing flying cars. SkyDrive now has a staff of fifty. Also in 2018, the Japanese government formed the Public-Private Conference for Air Mobility made up of private companies, universities, and government ministries. The stated aim was to make flying vehicles a reality by 2023... Fukuzawa is also targeting 2023 to begin taxi services (single passenger and pilot) in the Osaka Bay area, flying between locations like Kansai and Kobe airports and tourist attractions such as Universal Studios Japan. These flights will take less than ten minutes — a practical nod to the limitations of the battery energy storage system. "What SkyDrive is proposing is entirely do-able," says Steve Wright, Senior Research Fellow in Avionics and Aircraft Systems at the University of West England. "Almost all rotor-only electric vertical takeoff and landing vehicles projects are limited to sub-30-minute endurance, which, with safety reserves, equate to about 10 to 20 minutes flying."

Is Hot Asphalt Increasing Air Pollution?

2020年9月7日 06:43
"A new study suggests fresh asphalt is a significant, yet overlooked, source of air pollution," reports Science. "In fact, the material's contribution to one kind of particulate air pollution could rival or even exceed that of cars and trucks." UPI reports: And its emissions double as its temperature increases from 104 to 140 degrees Fahrenheit, researchers found. Sunlight plays a key role in these asphalt emissions, with even moderate levels of sunshine tripling the release of air pollutants, according to the study published Sept. 2 in the journal Science Advances... In-use pavement usually gets as hot as between 117 and 153 degrees Fahrenheit in the summer, while roofs can reach 167 degrees, the study authors said. As the major contributors to air pollution get cut back — for example, through cleaner vehicle emissions — passive pollution sources like these will have a growing influence on the air we breathe, said Peter DeCarlo, an associate professor and air pollution expert with Johns Hopkins University, in Baltimore. "In doing that reduction, we are discovering these new sources that are now playing a more prominent role in our air pollution issues," DeCarlo said.... Asphalt probably contributes most to air pollution when it's freshly laid, DeCarlo added. During the paving process, asphalt is heated to as much as 248 to 320 degrees Fahrenheit, the researchers said. "If you've ever been around people laying asphalt, you smell it. It's clear something is getting into the air when that happens," DeCarlo said. But asphalt likely continues to emit air pollutants even after it's aged, when sunlight bakes the material, he noted. Switching to concrete for paving would help reduce emissions, he said, but concrete is not an ideal paving material in all locales. Another possible solution might be the application of "cool pavement" technology, where colored sealants are applied to paved surfaces so they reflect more solar energy and become less likely to heat up, Gentner said. Emissions might also vary with different asphalt application methods and different formulations of the paving product, Gentner suggested.
