Starting today, Ford electric vehicle owners can use one of Tesla's 2,400+ superchargers, but there's a hitch. "They'll need to get an adapter that Ford will provide for free, although the company won't start shipping those until the end of March," notes the Associated Press. Product Reviewer MKBHD also notes that non-Teslas will need to park in a spot that blocks 2 spots where a Tesla would take up one. "If the charge station fills up the remaining spots with Teslas, the app will show 1 charger as available but the parking spot is blocked by the Mach-E," adds MKBHD. From the report: Last May, Ford became the first automaker to reach an agreement with the Austin, Texas-based Tesla to charge on its network, which is the largest and most well-placed in the U.S. Tesla has more than 26,000 plugs and nearly 2,400 Supercharger stations across the U.S. and Canada. Ford said its owners will have access to about 15,000 Tesla fast-charging plugs that are located strategically along travel corridors. Ford owners won't be able to use some older Tesla plugs.

Most other automakers followed Ford in joining Tesla's network and agreeing to switch to Tesla's plug, called the North American Charging Standard, which is smaller and easier to use than the current plugs on most other EVs sold in the two countries. Ford said adding the Tesla plugs will double the size of the network that can be used by Ford EV owners. There are nearly 166,000 Ford EVs in the U.S.

Ford is offering the adapters for free to the owners, who can sign up on the Ford.com website to reserve them between Thursday and June 30. The company will provide one free adapter per vehicle. Tesla's network was turned on Wednesday morning, and software enabling the Ford vehicles to charge at Tesla stations was to be sent out around the same time. Ford will switch to Tesla's charging connector with its second-generation EVs starting next year.

Intel's previously-unannounced Intel 10A (analogous to 1nm) will enter production/development in late 2027, marking the arrival of the company's first 1nm node, and its 14A (1.4nm) node will enter production in 2026. The company is also working to create fully autonomous AI-powered fabs in the future. Tom's Hardware: Intel's Keyvan Esfarjani, the company's EVP and GM and Foundry Manufacturing and Supply, held a very insightful session that covered the company's latest developments and showed how the roadmap unfolds over the coming years. Here, we can see two charts, with the first outlining the company's K-WSPW (thousands of wafer starts per week) capacity for Intel's various process nodes. Notably, capacity typically indicates how many wafers can be started, but not the total output -- output varies based on yields. You'll notice there isn't a label for the Y-axis, which would give us a direct read on Intel's production volumes. However, this does give us a solid idea of the proportionality of Intel's planned node production over the next several years.

Intel did not specify the arrival date of its coming 14A node in its previous announcements, but here, the company indicates it will begin production of the Intel 14A node in 2026. Even more importantly, Intel will begin production/development of its as-yet-unannounced 10A node in late 2027, filling out its roster of nodes produced with EUV technology. Intel's 'A' suffix in its node naming convention represents Angstroms, and 10 Angstroms converts to 1nm, meaning this is the company's first 1nm-class node. Intel hasn't shared any details about the 10A/1nm node but has told us that it classifies a new node as at least having a double-digit power/performance improvement. Intel CEO Pat Gelsinger has told us the cutoff for a new node is around a 14% to 15% improvement, so we can expect that 10A will have at least that level of improvement over the 14A node. (For example, the difference between Intel 7 and Intel 4 was a 15% improvement.)

A federal judge in Texas has granted a temporary order blocking the U.S. government from monitoring the energy usage of cryptocurrency mining operations, stating that the industry had shown it would suffer "irreparable injury" if it was made to comply. The Guardian reports: The US Department of Energy had launched an "eemergency" initiative last month aimed at surveying the energy use of mining operations, which typically use vast amounts of computing power to solve various mathematical puzzles to add new tokens to an online network known as a blockchain, allowing the mining of currency such as bitcoin. The growth of cryptocurrency, and the associated mining of it, has been blamed for a surge in electricity use as data centers have sprung up across the US, even reviving, in some cases, ailing coal plants to help power the mining. [...]

"The massive energy consumption of cryptocurrency mining and its rapid growth in the United States threaten to undermine progress towards achieving climate goals, and threaten grids, communities and ratepayers," said Mandy DeRoche, deputy managing attorney of the clean energy program at Earthjustice. Until now, a lack of publicly available information has only benefited an "industry that has thrived in the shadows," DeRoche added.

The crypto mining industry, however, has claimed it is the victim of a "politically motivated campaign" by Joe Biden's administration and has, for now, succeeded in averting a survey that it contends is unfairly onerous. "This is an attack against legitimate American businesses with the administration feigning an emergency to score political points," said Lee Bratcher, president the Texas Blockchain Council, one of the groups that sued to stop the survey. "The White House has been clear that they desire to 'to limit or eliminate' bitcoin miners from operating in the United States. "Although bitcoin is resilient and cannot be banned, the administration is seeking to make the lives of bitcoin miners, their employees, and their communities too difficult to bear operating in the United States. This is deeply concerning."

Optical discs that can store up to 200 TB of data could be possible with a new technology developed in China. If commercialized, it could revive optical media as an alternative to hard disk or tape for cost-effective long-term storage. The Register: Researchers at the University of Shanghai for Science and Technology (USST) and Shanghai Institute of Optics and Fine Mechanics (SIOM) say they have demonstrated that optical storage is possible up to the petabit level by using hundreds of layers, while also claiming to have broken the optical diffraction barrier limiting how close together recorded features can be.

In an article published in Nature titled "A 3D nanoscale optical disk memory with petabit capacity," the researchers detail how they developed a novel optical storage medium they call dye-doped photoresist (DDPR) with aggregation-induced emission luminogens (AIE-DDPR). When applied as a recording layer, this is claimed to outperform other optical systems and hard drives in terms of areal density -- the amount of storage per unit of area. To be specific, the researchers claim it to be 125 times that of a multi-layer optical disk based on gold nanorods, and 24 times that of the most advanced hard drives (based on data from 2022). The proposed recording and retrieval processes for this medium calls for two laser beams each. For optical writing, a 515 nm femtosecond Gaussian laser beam and a doughnut-shaped 639 nm continuous wave laser beam are focused on the recording area.

Maker Roni Bandini developed a Raspberry Pi project to address his neighbors' loud reggaeton music by creating an AI-driven system that distorts audio on nearby Bluetooth speakers when reggaeton is detected. Tom's Hardware reports: Powering this Bluetooth jamming device is a Raspberry Pi 3 B+. It's connected to a DFRobot OLED display panel, which has a resolution of 128 x 32px. Audio is observed using a USB microphone, while a push button handles when the system will perform a check to listen for any potential reggaeton. According to Bandini, the Pi is running Raspberry Pi OS. The AI system driving the machine learning aspects of the design is Edge Impulse. With this, Bandini was able to train the Pi to listen for music and more specifically identify whether the song playing is classifiable as reggaeton or not. The official project page is available at Hackster.

During a briefing at Mobile World Congress in Barcelona, Meghana Patwardhan, VP of Commercial Mobility at Dell Technology, told The Register that while the immediate future would consist of two worlds -- one with AI hardware and one without -- "every PC is going to be an AI PC in the longer term." From the report: In terms of new hardware, Dell used the Mobile World Congress event in Barcelona to show off new versions of its Surface-baiting Latitude 7350 convertible -- "the world's most serviceable commercial detachable," according to the company -- and its workstation-class Precision 3680 tower. Other devices in the Precision range include mobile workstations and the 3280 Compact Form Factor PC. Dell was also determined to present itself as a leader in hybrid working with the Premier Wireless ANC headset, replete with AI-based noise cancellation.

Duringt our talk, AI was never far from the lips of Dell's spokespeople as the company talked up the energy efficiency and future-proofing it saw in dedicated AI hardware, such as Neural Processing Units (NPUs) that are increasingly cropping up in CPUs. To illustrate the point, Dell boatsed about how much more efficient background blurring is on video calls when AI hardware is running compared to when it isn't. Hopefully, Microsoft will soon deliver a version of Windows capable of demonstrating a use for AI hardware that is more than hiding distractions in the background.

OpenAI, Microsoft, Nvidia, and Jeff Bezos are all part of a pack of investors in a business "developing human-like robots," reports Bloomberg, "according to people with knowledge of the situation..."

At the startup — which is named "Figure" — engineers "are working on a robot that looks and moves like a human. The company has said it hopes its machine, called Figure 01, will be able to perform dangerous jobs that are unsuitable for people and that its technology will help alleviate labor shortages." Figure is raising about $675 million in a funding round that carries a pre-money valuation of roughly $2 billion, said the people, who asked not to be identified because the matter is private. Through his firm Explore Investments LLC, Bezos has committed $100 million. Microsoft is investing $95 million, while Nvidia and an Amazon.com Inc.-affiliated fund are each providing $50 million... Other technology companies are involved as well. Intel Corp.'s venture capital arm is pouring in $25 million, and LG Innotek is providing $8.5 million. Samsung's investment group, meanwhile, committed $5 million. Backers also include venture firms Parkway Venture Capital, which is investing $100 million, and Align Ventures, which is providing $90 million...

The AI robotics industry has been busy lately. Earlier this year, OpenAI-backed Norwegian robotics startup 1X Technologies AS raised $100 million. Vancouver-based Sanctuary AI is developing a humanoid robot called Phoenix. And Tesla Inc. is working on a robot called Optimus, with Elon Musk calling it one of his most important projects. Agility Robotics, which Amazon backed in 2022, has bots in testing at one of the retailer's warehouses. Bloomberg calls the investments in Figure "part of a scramble to find new applications for artificial intelligence."

At CNN's product review site, one electronics reporter wrote they were "dumbfounded", "surprised," and "shocked" by the transparent screen on Lenovo's ThinkBook Transparent Display prototype. "This Micro LED screen is no slouch, either; a Full HD panel with up to 1,000 nits of brightness..." Let's get the big issue out of the way early: Lenovo is merely boasting what it can do, not what it will do. That's what a "concept" product means, of course. That said, it's still the most exciting thing I've seen in laptops in quite some time...

Thinking of major use cases for such a laptop, I basically considered any time you're out in public and want a more complete world view. While websites with white backgrounds look more opaque than transparent, the black backgrounds of a Notepad document and animations of space and fish fit the experience much better, as I could see the plants that Lenovo had placed behind the screen. The more websites use dark modes, the better this will go, too. Admittedly, I can also imagine some will blanch at the fact that such a laptop completely removes your privacy as a user. From those shopping for loved ones in the same room to those working on important business documents, the ThinkBook Transparent Display laptop could use a non-transparent mode, just like the LG OLED T offers. That said, I'm sure teachers would love to see what their kids are working on in the classroom.
The Verge calls it "an exceptionally cool-looking device that's capable of some fun novelties." The key draw is its bezel-less 17.3-inch MicroLED display, which offers up to 55 percent transparency when its pixels are set to black and turned off. But as its pixels light up, the display becomes less and less see-through, until eventually, you're looking at a completely opaque white surface with a peak brightness of 1,000 nits... How often, of course, do you actually want to see the empty desk behind your laptop? Would it be beneficial to be able to see your colleague sitting across from you, or would it be distracting? One of Lenovo's big ideas is that the form factor could be useful for digital artists, helping them to see the world behind the laptop's screen while sketching it on the lower half of the laptop where the keyboard is (more on this later).... 720p still feels like a very work-in-progress spec on a 17.3-inch laptop like this, but at least text shown on the screen during my demo was perfectly readable... Lenovo's transparent laptop concept feels like a collection of cool technologies in search of a killer app.
And yet Lenovo's executive director of ThinkPad portfolio and product Tom Butler tells the Verge he has "very high confidence" this will be in a real laptop within the next five years. (The Verge add that he "hopes that revealing this proof of concept will start a public conversation about what it could be useful for, setting a target for Lenovo to work toward.")

But would you use a laptop with a transparent screen?

Long-time Slashdot reader BishopBerkeley writes: Though it does not come as much of a surprise, a new study highlighted in IEEE Spectrum delves into how corporate profit motives are preventing the upgrading and the expansion of the U.S. electrical grid. The full report can be downloaded here from the source [the nonprofit economic research group NBER].

Besides opening up the market to competition, utilities don't want to lose control over regional infrastructure, writes IEEE Spectrum. "[I]nterregional lines threaten utility companies' dominance over the nation's power supply. In the power industry, asset ownership provides control over rules that govern energy markets and transmission service and expansion. When upstart entities build power plants and transmission lines, they may be able to dilute utility companies' control over power-industry rules and prevent utilities from dictating decisions about transmission expansion."
The article begins by noting that "The United States is not building enough transmission lines to connect regional power networks. The deficit is driving up electricity prices, reducing grid reliability, and hobbling renewable-energy deployment. " Utilities can stall transmission expansion because out-of-date laws sanction these companies' sweeping control over transmission development... One of the main values of connecting regional networks is that it enablesâ"and is in fact critical forâ"incorporating renewable energy... Plus, adding interregional transmission for renewables can significantly reduce costs for consumers. Such connections allow excess wind and solar power to flow to neighboring regions when weather conditions are favorable and allow the import of energy from elsewhere when renewables are less productive.

Even without renewables, better integrated networks generally lower costs for consumers because they reduce the amount of generation capacity needed overall and decrease energy market prices. Interregional transmission also enhances reliability,particularly during extreme weather...

Addressing the transmission shortage is on the agenda in Washington, but utility companies are lobbying against reforms.
The article points out that now investors and entrepreneurs "are developing long-distance direct-current lines, which are more efficient at moving large amounts of energy over long distances, compared with AC," and also "sidestep the utility-dominated transmission-expansion planning processes."

They're already in use in China, and are also becoming Europe's preferred choice...

Popular Science points out that for encoding data, "optical disks almost always offer just a single, 2D layer — that reflective, silver underside."

"If you could boost a disk's number of available, encodable layers, however, you could hypothetically gain a massive amount of extra space..." Researchers at the University of Shanghai for Science and Technology recently set out to do just that, and published the results earlier this week in the journal, Nature. Using a 54-nanometer laser, the team managed to record a 100 layers of data onto an optical disk, with each tier separated by just 1 micrometer. The final result is an optical disk with a three-dimensional stack of data layers capable of holding a whopping 1 petabit (Pb) of information — that's equivalent to 125,000 gigabytes of data...

As Gizmodo offers for reference, that same petabit of information would require roughly a six-and-a-half foot tall stack of HHD drives — if you tried to encode the same amount of data onto Blu-rays, you'd need around 10,000 blank ones to complete your (extremely inefficient) challenge.

To pull off their accomplishment, engineers needed to create an entirely new material for their optical disk's film... AIE-DDPR film utilizes a combination of specialized, photosensitive molecules capable of absorbing photonic data at a nanoscale level, which is then encoded using a high-tech dual-laser array. Because AIE-DDPR is so incredibly transparent, designers could apply layer-upon-layer to an optical disk without worrying about degrading the overall data. This basically generated a 3D "box" for digitized information, thus exponentially raising the normal-sized disk's capacity.

An anonymous reader shared this report from Electrek: Renewable developer Clearway Energy Group has completed a 452-megawatt (MW) solar farm in West Texas — and it's huge... It's built on around 5,000 acres of land and features over 1.1 million solar panels... Texas Solar Nova will generate enough electricity to power over 190,000 homes annually.

It's got an offtake agreement with telecoms giant Verizon, and agreements with auto component maker Toyota Boshoku and Swedish bearing and seal maker SKF to purchase renewable energy certificates (RECs). Both Toyota Boshoku and SKF have 12-year agreements for RECs.
The $660 million facility will "contribute significantly to the local tax base," the company said in a statement, "starting with an estimated $5.4 million in property taxes and wages to be paid in the first year."

"Crypto mines will have to start reporting their energy use in the U.S.," wrote the Verge in January, saying America's Energy department would "begin collecting data on crypto mines' electricity use, following criticism from environmental advocates over how energy-hungry those operations are."

But then "constitutional freedoms" group New Civil Liberties Alliance (founded with seed money from the Charles Koch Foundation) objected. And "on behalf of its clients" — the Texas Blockchain Council and Colorado bitcoin mining company Riot Platforms — the group said it "looks forward to derailing the Department of Energy's unlawful data collection effort once and for all."

While America's Energy department said the survey would take 30 minutes to complete, the complaint argued it would take 40 hours. According to the judge, the complaint "alleged three main sources of irreparable injury..."

- Nonrecoverable costs of compliance with the Survey
- A credible threat of prosecution if they do not comply with the Survey
- The disclosure of proprietary information requested by the Survey, thus risking disclosure of sensitive business strategy

But more importantly, the survey was implemented under "emergency" provisions, which the judge said is only appropriate when "public harm is reasonably likely to result if normal clearance procedures are followed."

Or, as Semafor.com puts it, the complaint was "seeking to push off the reporting deadline, on the grounds that the survey was rushed through...without a public comment period." The judge, Alan Albright, granted the request late Friday night, blocking the [Department of Energy's Information Administration] from collecting survey data or requiring bitcoin companies to respond to it, at least until a more comprehensive injunction hearing scheduled for Feb. 28. The ruling also concludes that the plaintiffs are "likely to succeed in showing that the facts alleged by the U.S. Energy Information Administration to support an emergency request fall far short of justifying such an action."
The U.S. Department of Energy is now...

• Restrained from requiring Plaintiffs or their members to respond to the Survey
• Restrained from collecting data required by the Survey
• "...and shall sequester and not share any such data that Defendants have already received from Survey respondents."

An anonymous reader shared this report from CNN: Dynabook Americas, the company formerly known as Toshiba, has recalled 15.5 million Toshiba laptop AC adapters over potential burn and fire hazards.

The company said it received 679 reports of the recalled AC adapters overheating or catching on fire, melting and burning, including 43 reports of minor burn injuries. Consumers should stop using the adapters immediately and contact them for a free replacement, Dynabook Americas said.

The recall applies to AC adapters sold both alongside Toshiba personal laptop computers and sold separately, with date codes ranging between April 2008 through December 2012. The adapters were manufactured in China. More than 60 models are part of the recall. The company published a webpage listing the impacted model numbers and serial numbers for the adapters.
Gatner points out the adapters are for "very old models," so "it's only a very small percentage of the population that is still using them."

The article cites figures from Gartner showing that while Toshiba once led the laptop market, it now makes up about 1%. "Nowadays, Lenovo dominates the category with 25%, followed by HP (22%), Dell (17%) and Apple (9%)."

An anonymous reader quotes a report from Ars Technica: India's plan to let a moratorium on imposing customs duties on cross-border digital e-commerce transactions expire may end up hurting India's more ambitious plans to become a global chip leader in the next five years, Reuters reported. It could also worsen the global chip shortage by spiking semiconductor industry costs at a time when many governments worldwide are investing heavily in expanding domestic chip supplies in efforts to keep up with rapidly advancing technologies.

Early next week, world leaders will convene at a World Trade Organization (WTO) meeting, just before the deadline to extend the moratorium hits in March. In place since 1998, the moratorium has been renewed every two years since -- but India has grown concerned that it's losing significant revenues from not imposing taxes as demand rises for its digital goods, like movies, e-books, or games. Hoping to change India's mind, a global consortium of semiconductor industry associations known as the World Semiconductor Council (WSC) sent a letter to Indian Prime Minister Narendra Modi on Thursday. Reuters reviewed the letter, reporting that the WSC warned Modi that ending the moratorium "would mean tariffs on digital e-commerce and an innumerable number of transfers of chip design data across countries, raising costs and worsening chip shortages."

Pointing to Modi's $10 billion semiconductor incentive package -- which Modi has said is designed to advance India's industry through "giant leaps" in its mission to become a technology superpower -- the WSC cautioned Modi that pushing for customs duties may dash those global chip leader dreams. Studies suggest that India should be offering tax incentives, not potentially threatening to impose duties on chip design data. That includes a study from earlier this year, released after the Semiconductor Industry Association and the India Electronics and Semiconductor Association commissioned a report from the Information Technology and Innovation Foundation (ITIF). [...] It's possible that India and other developing nations may seek to narrow the moratorium rather than end it. An Indian government official told Reuters that "these issues need to be discussed and settled" before India can make a decision on whether to extend the moratorium.

Humane announced that its AI Pin would start shipping in March, but there's been a small delay. From a report: Early adopters are now being told orders will arrive in mid-April at the earliest, according to a video update from Humane staffer Sam Sheffer and emails we saw in Humane's official Discord channel. On the plus side, the company says it'll now throw in three months of its pricy $24-a-month subscription for free with the $699 pin -- and will do so for any other customers who buy one before March 31st, too.

An anonymous reader quotes a report from Princeton Engineering: In the blink of an eye, the unruly, superheated plasma that drives a fusion reaction can lose its stability and escape the strong magnetic fields confining it within the donut-shaped fusion reactor. These getaways frequently spell the end of the reaction, posing a core challenge to developing fusion as a non-polluting, virtually limitless energy source. But a Princeton-led team composed of engineers, physicists, and data scientists from the University and the Princeton Plasma Physics Laboratory (PPPL) have harnessed the power of artificial intelligence to predict -- and then avoid -- the formation of a specific plasma problem in real time.

In experiments at the DIII-D National Fusion Facility in San Diego, the researchers demonstrated their model, trained only on past experimental data, could forecast potential plasma instabilities known as tearing mode instabilities up to 300 milliseconds in advance. While that leaves no more than enough time for a slow blink in humans, it was plenty of time for the AI controller to change certain operating parameters to avoid what would have developed into a tear within the plasma's magnetic field lines, upsetting its equilibrium and opening the door for a reaction-ending escape.

"By learning from past experiments, rather than incorporating information from physics-based models, the AI could develop a final control policy that supported a stable, high-powered plasma regime in real time, at a real reactor," said research leader Egemen Kolemen, associate professor of mechanical and aerospace engineering and the Andlinger Center for Energy and the Environment, as well as staff research physicist at PPPL. The research opens the door for more dynamic control of a fusion reaction than current approaches, and it provides a foundation for using artificial intelligence to solve a broad range of plasma instabilities, which have long been obstacles to achieving a sustained fusion reaction. The team published their findings in the journal Nature.

It's no surprise that the broader tech industry has largely moved away from physical disks to digital subscription-based models. But Microsoft's Gaming CEO Phil Spencer says Xbox isn't trying to do away with disks just yet -- even though making disk slots could become challenging in the future. From a report: "Our strategy does not hinge on people moving all-digital," Spencer said in a recent interview with Game File. "Getting rid of physical, that's not a strategic thing for us." While Spencer implied that disk slots have become somewhat old-school at this point, Xbox consoles will continue to offer both disk-compatible and diskless options if gamers still want to choose. Xbox hasn't confirmed yet whether the previously leaked diskless Xbox refresh of the Series X console is still coming, though.

"Gaming consoles themselves have kind of become the last consumer electronic device that has a drive," Spencer conceded, calling it a "real issue." Because so few manufacturers are still making physical disk slots, it's possible making consoles with them could become cost prohibitive in the future. "When you think about cogs that we're going to go put in a console -- and as you have fewer suppliers and fewer buyers -- the cost of the drive does have an impact," Spencer said.

Meta CEO Mark Zuckerberg said that it's working on a finger tracking neural wristband that will be ready to ship "in the next few years." UploadVR reports: Appearing on the Morning Brew Daily talk show on Friday, Mark Zuckerberg said "we're actually kind of close to having something here that we're going to have in a product in the next few years." [...] An entirely different approach to finger tracking is to sense the neural electrical signals passing through your wrist to your fingers from your brain, using a technique called electromyography (EMG). Theoretically this could have zero or even negative latency, perfect accuracy, work regardless of lighting conditions, and not be subject to occlusion. When discussing the technology in 2021 Reardon claimed that a recent breakthrough enabled decoding the activity of individual neurons for "almost infinite control over machines." Occlusion-free finger tracking of this quality and reliability could enable precise control of complex interfaces with incredibly subtle movements of your hand resting on your lap, making it an ideal input method for headsets and AR glasses. [...]

So how will this arrive in a Meta product? In early 2023 an internal Meta AR/VR hardware roadmap leaked to The Verge, revealing details about Quest 3, the existence of the headset now rumored to be called Quest 3 Lite, and the cancelation of the 2024 candidate for Quest Pro 2 in favor of a more ambitious but "way out" model. But this roadmap also mentioned that Meta was planning to release the neural wristband alongside the third generation Ray-Ban smartglasses in 2025 as the input method.

According to that roadmap, two models of the wristband will be offered at different price points - one with the neural input tech only and another that also has a display and camera to act as a smartwatch too. A second generation of the wristband will also apparently act as the input device for the true AR glasses Meta plans to launch in 2027. We should however note that this plan or the timeline may have changed in the year since.

"After years of rapid expansion, California's booming EV market may be showing signs of fatigue," reports the Los Angeles Times, "as high vehicle prices, unreliable charging networks and other consumer headaches appear to dampen enthusiasm for zero-emission vehicles.

"For the first time in more than a decade, electric vehicle sales dropped significantly in the last half of 2023..." Sales of all-electric cars and light trucks in California had started off strong in 2023, rising 48% in the first half of the year compared with a year earlier. By that time, California EV sales numbered roughly 190,807 — or slightly more than a quarter of all EV sales in the nation, according to the California New Car Dealers Assn. But it's what happened in the second half of last year though that's generating jitters. Sales in the third quarter fell by 2,840 from the previous period — the first quarterly drop for EVs in California since the Tesla Model S was introduced in 2012. And the fourth quarter was even worse: Sales dropped 10.2%, from 100,151 to 89,933...

Propelled by the sales success of Tesla, and boosted by electric vehicles from other automakers entering the market, consumer acceptance of EVs had seemed like a given until recently. In fact, robust sales growth is a key assumption in the state's zero-emission vehicle plan... Under the no-gas mandate, zero-emission vehicles must account for 35% of all new vehicle sales by model year 2026.... Nationally, EV sales growth also has slowed as automakers such as Ford and General Motors cut back — at least temporarily — on EV and battery production plans. Hertz, the rental car giant, is also pulling back on plans to shift heavily toward EVs. Hertz several years ago announced plans to buy 100,000 Teslas but is now selling off its EV fleet.

Corey Cantor, EV analyst at Bloomberg BNEF, an energy research firm, said that although recent sales figures are worrisome, there's plenty of momentum behind the EV transition, as evidenced by government mandates around the globe and massive investments by motor vehicle manufacturers and their suppliers. Those investments total $616 billion globally over five years, according to consulting firm AlixPartners.
But EVs haven't reached "price parity" with gas-powered engines, the article points out, so just 7.6% of the vehicles sold last year in the U.S. were electric — while in California, the market share for EVS was 20.1%.

The article also quantifies concerns about reliability of California's public charging system, which "according to studies from academic researchers and market analysts, can be counted on to malfunction at least 20% of the time." After $1 billion in state money for charger companies, the state's Energy Commission will now also start collecting reliability statistics, according to the article. But the article also cites wait times at the chargers. "Even if they were reliable, there aren't enough chargers to go around. EV sales have outpaced public charger installation."

Some good news? The federal government is spending $5 billion nationally to put fast chargers on major highways at 50-mile intervals. California will receive $384 million. Seven major automakers have also teamed up to build a North American charging network of their own, called Ionna. The joint venture plans to install at least 30,000 chargers — which would be open to any EV brand — at stations that will provide restrooms, food service and retail stores on site or nearby.

High-capacity DNA data storage "is closer than you think," Slashdot wrote in 2019.

Now IEEE Spectrum brings an update on where we're at — and where we're headed — by a participant in the DNA storage collaboration between Microsoft and the Molecular Information Systems Lab of the Paul G. Allen School of Computer Science and Engineering at the University of Washington. "Organizations around the world are already taking the first steps toward building a DNA drive that can both write and read DNA data," while "funding agencies in the United States, Europe, and Asia are investing in the technology stack required to field commercially relevant devices." The challenging part is learning how to get the information into, and back out of, the molecule in an economically viable way... For a DNA drive to compete with today's archival tape drives, it must be able to write about 2 gigabits per second, which at demonstrated DNA data storage densities is about 2 billion bases per second. To put that in context, I estimate that the total global market for synthetic DNA today is no more than about 10 terabases per year, which is the equivalent of about 300,000 bases per second over a year. The entire DNA synthesis industry would need to grow by approximately 4 orders of magnitude just to compete with a single tape drive. Keeping up with the total global demand for storage would require another 8 orders of magnitude of improvement by 2030. But humans have done this kind of scaling up before. Exponential growth in silicon-based technology is how we wound up producing so much data. Similar exponential growth will be fundamental in the transition to DNA storage...

Companies like DNA Script and Molecular Assemblies are commercializing automated systems that use enzymes to synthesize DNA. These techniques are replacing traditional chemical DNA synthesis for some applications in the biotechnology industry... [I]t won't be long before we can combine the two technologies into one functional device: a semiconductor chip that converts digital signals into chemical states (for example, changes in pH), and an enzymatic system that responds to those chemical states by adding specific, individual bases to build a strand of synthetic DNA. The University of Washington and Microsoft team, collaborating with the enzymatic synthesis company Ansa Biotechnologies, recently took the first step toward this device... The path is relatively clear; building a commercially relevant DNA drive is simply a matter of time and money...

At the same time, advances in DNA synthesis for DNA storage will increase access to DNA for other uses, notably in the biotechnology industry, and will thereby expand capabilities to reprogram life. Somewhere down the road, when a DNA drive achieves a throughput of 2 gigabases per second (or 120 gigabases per minute), this box could synthesize the equivalent of about 20 complete human genomes per minute. And when humans combine our improving knowledge of how to construct a genome with access to effectively free synthetic DNA, we will enter a very different world... We'll be able to design microbes to produce chemicals and drugs, as well as plants that can fend off pests or sequester minerals from the environment, such as arsenic, carbon, or gold. At 2 gigabases per second, constructing biological countermeasures against novel pathogens will take a matter of minutes. But so too will constructing the genomes of novel pathogens. Indeed, this flow of information back and forth between the digital and the biological will mean that every security concern from the world of IT will also be introduced into the world of biology...

The future will be built not from DNA as we find it, but from DNA as we will write it.
The article makes an interesting point — that biology labs around the world already order chemically-synthesized ssDNA, "delivered in lengths of up to several hundred bases," and sequence DNA molecules up to thousands of bases in length.

"In other words, we already convert digital information to and from DNA, but generally using only sequences that make sense in terms of biology."
