12:45a	Alphabet Puts Prototype Robots To Work Cleaning Up Google's Offices The company announced today that its Everyday Robots Project -- a team within its experimental X labs dedicated to creating "a general-purpose learning robot" -- has moved some of its prototype machines out of the lab and into Google's Bay Area campuses to carry out some light custodial tasks. The Verge reports: "We are now operating a fleet of more than 100 robot prototypes that are autonomously performing a range of useful tasks around our offices," said Everyday Robot's chief robot officer Hans Peter Brondmo in a blog post. "The same robot that sorts trash can now be equipped with a squeegee to wipe tables and use the same gripper that grasps cups can learn to open doors." These robots in question are essentially arms on wheels, with a multipurpose gripper on the end of a flexible arm attached to a central tower. There's a "head" on top of the tower with cameras and sensors for machine vision and what looks like a spinning lidar unit on the side, presumably for navigation. As Brondmo indicates, these bots were first seen sorting out recycling when Alphabet debuted the Everyday Robot team in 2019. The big promise that's being made by the company (as well as by many other startups and rivals) is that machine learning will finally enable robots to operate in "unstructured" environments like homes and offices.

1:25a	Ford Plans To Produce 600,000 EVs a Year By the End of 2023 Ford CEO Jim Farley announced that the automaker is planning to produce 600,000 electric vehicles per year by the end of 2023, "which will double the number of EVs it originally intended to manufacture," notes Engadget. From the report: According to Automotive News, production will be spread across the Mustang Mach-E, F-150 Lightning and E-Transit. Ford's current EV lineup is wildly popular, Farley said, and the demand is "so much higher" than the company expected. The Mustang Mach-E is selling on three continents, while the Ford F-150 Lightning has been popular from the time it was announced. Ford received 100,000 reservations within three weeks after it was unveiled, and that number's now up to 160,000 -- all placed with a $100 refundable deposit. Due to the high demand for the F-150, Ford previously decided to invest $250 million to boost its production, creating 450 new jobs to help it make 80,000 trucks a year. It's unclear how much that target would change now that the company is doubling its manufacturing goal. Read more of this story at Slashdot. (Comment on this)
2:02a	First Electric Autonomous Cargo Ship Launched In Norway Zero emissions and, soon, zero crew: the world's first fully electric autonomous cargo vessel was unveiled in Norway, a small but promising step toward reducing the maritime industry's climate footprint. TechXplore reports: By shipping up to 120 containers of fertilizer from a plant in the southeastern town of Porsgrunn to the Brevik port a dozen kilometres (about eight miles) away, the much-delayed Yara Birkeland, shown off to the media on Friday, will eliminate the need for around 40,000 truck journeys a year that are now fueled by polluting diesel. The 80-meter, 3,200-deadweight tonne ship will soon begin two years of working trials during which it will be fine-tuned to learn to maneuver on its own. The wheelhouse could disappear altogether in "three, four or five years", said Holsether, once the vessel makes its 7.5-nautical-mile trips on its own with the aid of sensors. "Quite a lot of the incidents happening on vessels are due to human error, because of fatigue for instance," project manager Jostein Braaten said from the possibly doomed bridge. "Autonomous operating can enable a safe journey," he said. On board the Yara Birkeland, the traditional machine room has been replaced by eight battery compartments, giving the vessel a capacity of 6.8 MWh -- sourced from renewable hydroelectricity. "That's the equivalent of 100 Teslas," says Braaten. The maritime sector, which is responsible for almost three percent of all man-made emissions, aims to reduce its emissions by 40 percent by 2030 and 50 percent by 2050. Despite that, the sector has seen a rise in recent years. Read more of this story at Slashdot. (Comment on this)
3:34p	Texas Plans To Become the Bitcoin Capital, Vulnerable Power Grid and All An anonymous reader quotes a report from Bloomberg: Texas, already home to the most vulnerable power grid in the U.S., is about to be hit by a surge in demand for electricity that's twice the size of Austin's. An army of cryptocurrency miners heading to the state for its cheap power and laissez-faire regulation is forecast to send demand soaring by as much as 5,000 megawatts over the next two years. The crypto migration to Texas has been building for months, but the sheer volume of power those miners will need -- two times more than the capital city of almost 1 million people consumed in all of 2020 -- is only now becoming clear. The boom comes as the electrical system is already under strain from an expanding population and robust economy. Even before the new demand comes online, the state's grid has proven to be lethally unreliable. Catastrophic blackouts in February plunged millions into darkness for days, and, ultimately, led to at least 210 deaths. Proponents like Senator Ted Cruz and Governor Greg Abbott, both Republicans, say crypto miners are ultimately good for the grid, since they say the miners can soak up excess clean power and, when needed, can voluntarily throttle back in seconds to help avert blackouts. But it raises the question of what these miners will do when the state's electricity demand inevitably outstrips supply: Will they adhere to an honor system of curtailing their power use, especially when the Bitcoin price is itself so high, or will it mean even more pressure on an overwhelmed grid? Miners setting up shop in the Lone Star State can often count on a 10-year tax abatement, sales tax credits and workforce training from the state, depending on where they are located and how many jobs they add. Even without formal incentives, the cheap power prices and the state's hands-off policy toward business is often enough of a lure. The pitch is working: The grid operator Electric Reliability Council of Texas, or Ercot, will account for about 20% of the Bitcoin network globally by the end of 2022, up from 8% to 10% today, according to Lee Bratcher, president of the Texas Blockchain council. Right now, Ercot has somewhere between 500 and 1,000 megawatts of mining capacity, out of about 2,000 nationwide. The state grid will add another 3,000 to 5,000 megawatts of mining demand by the end of 2023, he said. Read more of this story at Slashdot. (Comment on this)
5:34p	Could Fusion Energy Provide a Safer Alternative to Nuclear Power? "One way to help eliminate carbon emissions and thereby fight global warming may be to exploit fusion, the energy source of the sun and stars..." argues a new article in Bulletin of the Atomic Scientists (shared by Slashdot reader DanDrollette). Though fusion energy would involve controllng a "plasma" gas of positively charged nuclei and negatively charged electrons heated to 150 million degrees Celsius, progress is being made — and the upside could be tremendous: One major advantage of using fusion as an energy source is that its underlying physics precludes either a fuel meltdown — such as what happened at Three Mile Island and Fukushima Daichi — or a runaway reaction, such as at Chernobyl. Furthermore, the amount of radioactive material that could be released in an accident in a fusion power plant system is much less than in a fission reactor. Consequently, a fusion system has much less capability to damage itself, and any damage would have much less dangerous consequences. As a result, current concepts for fusion systems may not necessitate an evacuation plan beyond the site boundary. Another advantage of fusion is that neither the fuel nor its products create the very long-lived radioactive waste that fission does, which means that fusion does not require long-term, geological storage... When and how can fusion contribute to mitigating climate change? Private companies are in a hurry to develop fusion, and many say that they will be able to put commercial fusion power on the US electric grid in the early 2030s. The total private financing in this sector is impressive, at about $2 billion... After looking over the state of publicly and privately funded fusion research, the National Academies recommended that the United States embark upon a program to develop multiple preliminary designs for a fusion pilot plant by 2028, with the goal of putting a modest amount of net electricity on the U.S. electrical grid from a pilot plant starting sometime in the years between 2035 and 2040, use the pilot plant to study and develop technologies for fusion, and have a first-of-a-kind commercial fusion power plant operational by 2050. The United Kingdom has recently announced a plan to build a prototype fusion power plant by 2040. China has a plan to begin operation of a fusion engineering test reactor in the 2030s, while the European Union foresees operation of a demonstration fusion power plant in the 2050s... We must look beyond the 2035 timeframe to see how fusion can make a major contribution, and how it can complement renewables... [P]roviding low-carbon electricity in the world market, including later in the century, is of great importance for holding climate change at bay. Read more of this story at Slashdot.

11:25p	Is 'The NFT Bay' Just a Giant Hoax? Recently Australian developer Geoffrey Huntley announced they'd created a 20-terabyte archive of all NFTs on the Ethereum and Solana blockchains. But one NFT startup company now says they tried downloading the archive — and discovered most of it was zeroes. Many of the articles are careful to point out "we have not verified the contents of the torrent," because of course they couldn't. A 20TB torrent would take several days to download, necessitating a pretty beefy internet connection and more disk space to store than most people have at their disposal. We at ClubNFT fired up a massive AWS instance with 40TB of EBS disk space to attempt to download this, with a cost estimate of $10k-20k over the next month, as we saw this torrent as potentially an easy way to pre-seed our NFT storage efforts — not many people have these resources to devote to a single news story. Fortunately, we can save you the trouble of downloading the entire torrent — all you need is about 10GB. Download the first 10GB of the torrent, plus the last block, and you can fill in all the rest with zeroes. In other words, it's empty; and no, Geoff did not actually download all the NFTs. Ironically, Geoff has archived all of the media articles about this and linked them on TheNFTBay's site, presumably to preserve an immutable record of the spread and success of his campaign — kinda like an NFT... We were hoping this was real... [I]t is actually rather complicated to correctly download and secure the media for even a single NFT, nevermind trying to do it for every NFT ever made. This is why we were initially skeptical of Geoff's statements. But even if he had actually downloaded all the NFT media and made it available as a torrent, this would not have solved the problem... a torrent containing all the NFTs does nothing to actually make those NFTs available via IPFS, which is the network they must be present on in order for the NFTs to be visible on marketplaces and galleries.... [A]nd this is a bit in the weeds: in order to reupload an NFT's media to IPFS, you need more than just the media itself. In order to restore a file to IPFS so it can continue to be located by the original link embedded in the NFT, you must know exactly the settings used when that file was originally uploaded, and potentially even the exact version of the IPFS software used for the upload. For these reasons and more, ClubNFT is working hard on an actual solution to ensure that everybody's NFTs can be safely secured by the collectors themselves. We look forward to providing more educational resources on these and other topics, and welcome the attention that others, like Geoff, bring to these important issues. Their article was shared by Slashdot reader long-time Slashdot reader GradiusCVK (who is one of ClubNFT's three founders). I'd wondered suspiciously if ClubNFT was a hoax, but if this PR Newswire press release is legit, they've raised $3 million in seed funding. (And that does include an investment from Drapen Dragon, co-founded by Tim Draper which shows up on CrunchBase). The International Business Times has also covered ClubNFT, identifying it as a startup whose mission statement is "to build the next generation of NFT solutions to help collectors discover, protect, and share digital assets." Co-founder and CEO Jason Bailey said these next-generation tools are in their "discovery" phase, and one of the first set of tools that is designed to provide a backup solution for NFTs will roll out early next year. Speaking to International Business Times, Bailey said, "We are looking at early 2022 to roll out the backup solution. But between now and then we should be feeding (1,500 beta testers) valuable information about their wallets." Bailey says while doing the beta testing, he realized that there are loopholes in the NFT storage systems and only 40% of the NFTs were actually pointing to the IPFS, while 40% of them were at risk — pointing to private servers. Here is the problem explained: NFTs are basically a collection of metadata, that define the underlying property that is owned. Just like in the world of internet documents, links point to the art and any details about it that are being stored. But links can break, or die. Many NFTs use a system called InterPlanetary File System, or IPFS, which let you find a piece of content as long as it is hosted somewhere on the IPFS network. Unlike in the world of internet domains, you don't need to own the domain to really make sure the data is safe. Explaining the problem which the backup tool will address, Bailey said, "When you upload an image to IPFS, it creates a cryptographic hash. And if someone ever stops paying to store that image on IPFS, as long as you have the original image, you can always restore it. That's why we're giving people the right to download the image.... [W]e're going to start with this protection tool solution that will allow people to click a button and download all the assets associated with their NFT collection and their wallet in the exact format that they would need it in to restore it back up to IPFS, should it ever disappear. And we're not going to charge any money for that." The idea, he said, is that collectors should not have to trust any company; rather they can use ClubNFT's tool, whenever it becomes available, to download the files locally... "One of the things that we're doing early around that discovery process, we're building out a tool that looks in your wallet and can see who you collect, and then go a level deeper and see who they collect," Bailey said. Bailey said that the rest of the tools will process after gathering lessons based on user feedback on the first set of solutions. He, however, seemed positive that the talks of the next set of tools will begin in the Spring of next year as the company has laid a "general roadmap." Read more of this story at Slashdot.
