The Verge reports: Ford will soon start selling and shipping some Ford Explorers without the chips that power rear air conditioning and heating controls, according to a report from Automotive News. The automaker will instead ship the missing semiconductors to dealers within one year, which they will then install in customers' vehicles after purchase.

Ford spokesperson Said Deep told The Verge that heating and air condition will still be controllable from the front seats, and that customers who choose to purchase a vehicle without the rear controls will receive a price reduction. According to Deep, Ford is doing this as a way to bring new Explorers to customers faster, and that the change is only temporary.

The automaker originally had plans to ship partially-built, undrivable vehicles to dealers last year, but now, the unchipped vehicles will be both driveable and sellable. As pointed out by Automotive News, Ford's decision comes as an attempt to move the partially-built vehicles crowding its factory lots. Last month, hundreds of new Ford Broncos were spotted sitting idly in the snow-covered lots near Ford's Michigan Assembly Plant, all of which await chip-related installations....

Other automakers have also had to make sacrifices due to the chip shortage, with GM dropping wireless charging, HD radios, and a fuel management module that made some pickup trucks operate more efficiently.

Power blackouts and rising electricity costs have inspired "a small but growing number of Californians" to leave the power grid altogether for their own home-generated energy, reports the New York Times.

And thanks to "a stunning drop" in the cost of solar panels and batteries, "Some homeowners who have built new, off-grid homes say they have even saved money because their systems were cheaper than securing a new utility connection...." Nobody is quite sure how many off-grid homes there are but local officials and real estate agents said there were dozens here in Nevada County, a picturesque part of the Sierra Nevada range between Sacramento and Lake Tahoe. Some energy experts say that millions of people could eventually go off the grid as costs drop....

People going off the grid argue that utilities are not moving fast enough to address climate change and are causing other problems. In Northern California, Pacific Gas & Electric's safety record has alienated many residents. The company's equipment caused the 2018 Camp Fire, which killed dozens and destroyed the town of Paradise, about 70 miles north of Nevada City. The utility's effort to prevent fires by cutting off power to homes and businesses has also angered people. One of those residents is Alan Savage, a real estate agent in Grass Valley, who bought an off-grid home six years ago and has sold hundreds of such properties. He said he never loses power, unlike PG&E customers. "I don't think I'll ever go back to being on the grid," Mr. Savage said.

For people like him, it is not enough to take the approach favored by most homeowners with solar panels and batteries. Those homeowners use their systems to supplement the electricity they get from the grid, provide emergency backup power and sell excess energy to the grid.

The appeal of off-grid homes has grown in part because utilities have become less reliable. As natural disasters linked to climate change have increased, there have been more extended blackouts in California, Texas, Louisiana and other states.... Installing off-grid solar and battery systems is expensive, but once the systems are up and running, they typically require modest maintenance and homeowners no longer have an electric bill. RMI, a research organization formerly known as the Rocky Mountain Institute, has projected that by 2031 most California homeowners will save money by going off the grid as solar and battery costs fall and utility rates increase. That phenomenon will increasingly play out in less sunny regions like the Northeast over the following decades, the group forecasts....

Some energy experts worry that people who are going off the grid could unwittingly hurt efforts to reduce greenhouse gas emissions. That is because the excess electricity that rooftop solar panels produce will no longer reach the grid, where it can replace power from coal or natural gas plants. "We don't need everybody to cut the cord and go it alone," said Mark Dyson, senior principal with the carbon-free electricity unit of RMI.... Scott Aaronson, a senior vice president for security and preparedness at the Edison Electric Institute, a utility industry trade group, said that while off-grid living might appeal to some, it was "like having a computer not connected to the internet.... You're getting some value but you're not part of a greater whole," he said. "When something goes wrong, that's wholly on you...."

Off-grid systems are particularly attractive to people building new homes. That's because installing a 125- to 300-foot overhead power line to a new home costs about $20,000, according to the California Public Utilities Commission. In places where lines have to be buried, installation runs about $78,000 for 100 feet.
The article ends by pointing out that off-the-grid residents will soon also have a handy alternative to the giant electric batteries that store the excess energy from their solar panels: electric cars like the Ford F-150 Lightning and the Hyundai Ioniq 5.

"News of a fresh Spectre BHB vulnerability that only impacts Intel and Arm processors emerged this week," reports Tom's Hardware, "but Intel's research around these new attack vectors unearthed another issue.

"One of the patches that AMD has used to fix the Spectre vulnerabilities has been broken since 2018." Intel's security team, STORM, found the issue with AMD's mitigation. In response, AMD has issued a security bulletin and updated its guidance to recommend using an alternative method to mitigate the Spectre vulnerabilities, thus repairing the issue anew....

Intel's research into AMD's Spectre fix begins in a roundabout way — Intel's processors were recently found to still be susceptible to Spectre v2-based attacks via a new Branch History Injection variant, this despite the company's use of the Enhanced Indirect Branch Restricted Speculation (eIBRS) and/or Retpoline mitigations that were thought to prevent further attacks. In need of a newer Spectre mitigation approach to patch the far-flung issue, Intel turned to studying alternative mitigation techniques. There are several other options, but all entail varying levels of performance tradeoffs. Intel says its ecosystem partners asked the company to consider using AMD's LFENCE/JMP technique. The "LFENCE/JMP" mitigation is a Retpoline alternative commonly referred to as "AMD's Retpoline."

As a result of Intel's investigation, the company discovered that the mitigation AMD has used since 2018 to patch the Spectre vulnerabilities isn't sufficient — the chips are still vulnerable. The issue impacts nearly every modern AMD processor spanning almost the entire Ryzen family for desktop PCs and laptops (second-gen to current-gen) and the EPYC family of datacenter chips....

In response to the STORM team's discovery and paper, AMD issued a security bulletin (AMD-SB-1026) that states it isn't aware of any currently active exploits using the method described in the paper. AMD also instructs its customers to switch to using "one of the other published mitigations (V2-1 aka 'generic retpoline' or V2-4 aka 'IBRS')." The company also published updated Spectre mitigation guidance reflecting those changes [PDF]....

AMD's security bulletin thanks Intel's STORM team by name and noted it engaged in the coordinated vulnerability disclosure, thus allowing AMD enough time to address the issue before making it known to the public.

Walgreens and other retailers replaced some fridge and freezer doors with iPad-like screens, reports CNN. "And some shoppers absolutely hate it." The screens, which were developed by the startup Cooler Screens, use a system of motion sensors and cameras to display what's inside the doors — as well as product information, prices, deals and, most appealing to brands, paid advertisements. The tech provides stores with an additional revenue stream and a way to modernize the shopping experience. But for customers who just want to peek into the freezer and grab their ice cream, Walgreens risks angering them by solving a problem that shoppers didn't know existed. The company wants to engage more people with advertising, but the reaction, so far, is annoyance and confusion.

"Why would Walgreens do this?" one befuddled shopper who encountered the screens posted on TikTok. "Who on God's green earth thought this was a good idea?"

"The digital cooler screens at Walgreens made me watch an ad before it allowed me to know which door held the frozen pizzas," said someone on Twitter....

Walgreens began testing the screens in 2018 and has since expanded the pilot to a couple thousand locations nationwide. Several other major retailers are launching their own tests with Cooler Screens, including Kroger, CVS, GetGo convenience stores and Chevron gas stations. "I hope that we will one day be able to expand across all parts of the store," said Cooler Screens co-founder and CEO Arsen Avakian in an interview with CNN Business. Currently the startup has about 10,000 screens in stores, which are viewed by approximately 90 million consumers monthly, according to the company....

Politifact last month debunked a viral Facebook video that claimed "Walgreens refrigerators are scanning shoppers' hands and foreheads for 'the mark of the beast.'"

Avakian insists the tech is "identity-blind" and protects consumers' privacy. The freezers have front-facing sensors used to anonymously track shoppers interacting with the platform, while internally facing cameras track product inventory...

The items on display don't always match up with what's inside because products are out of stock.....

"This is the future of retail and shopping," Avakian said.
CNN notes that major corporations are backing the company Cooler Screens, which "has raised more than $100 million from backers including Microsoft and Verizon." But long-time Slashdot reader davidwr points out it's been done before. "Some gas stations have had video ads at the pump for years now. I boycott those stations on principle."

And Slashdot reader quonset wonders if we're one step closer to Futurama's vision of a world where advertisers enter our dreams.

Ukraine's two leading suppliers of neon, which produce about half the world's supply of the key ingredient for making chips, have halted their operations as Moscow has sharpened its attack on the country, threatening to raise prices and aggravate the semiconductor shortage. CNN Business reports: Some 45%-54% of the world's semiconductor grade neon, critical for the lasers used to make chips, comes from two Ukrainian companies, Ingas and Cryoin, according to Reuters calculations based on figures from the companies and market research firm Techcet. Global neon consumption for chip production reached about 540 metric tons last year, Techcet estimates. Both firms have shuttered their operations, according to company representatives contacted by Reuters, as Russian troops have escalated their attacks on cities throughout Ukraine, killing civilians and destroying key infrastructure. The stoppage casts a cloud over the worldwide output of chips, already in short supply after the coronavirus pandemic drove up demand for cell phones, laptops and later cars, forcing some firms to scale back production.

According to the latest updates from CNN, Ukraine's defense ministry claims Russia is planning to carry out "some sort of terrorist attack at the Chernobyl nuclear power plant" and blame Ukraine. The plant is currently without power and under Russian control. From the report: The Main Intelligence Directorate of the Ministry of Defence claimed on its Facebook page Friday that "the available intelligence says Putin has ordered that his troops to prepare a terror attack at Chernobyl for which the Russian invaders will try to blame Ukraine." The directorate also repeated that the plant "remains completely disconnected from the monitoring systems run by the International Atomic Energy Agency (IAEA)."

The Ukrainian Ministry of Defence also alleged Friday that Russian forces had denied a Ukrainian repair team access to Chernobyl. It claimed without offering evidence that "Belarusian specialists" went there posing as nuclear power experts and that Russian saboteurs were arriving to set up a terror attack. The ministry claimed that "without receiving the desired result from the ground military operation and direct talks, Putin is ready to resort to nuclear blackmail of the international community."

The IAEA said last week that it had not been able to re-establish communication with systems installed to monitor nuclear material and activities at either the Chernobyl or Zaporizhzhia plants following the loss of remote data transmissions from those systems. IAEA Director General Rafael Grossi said Thursday that the situation at the Chernobyl nuclear power plant, occupied by the Russian forces, was degrading as the IAEA was losing "a significant amount of information" on safeguarding monitoring systems. However, he said he was "quite encouraged [...] on one important thing, is that Ukraine and Russian Federation want to work with us, they agree to work with us." "Both Russia and Ukraine have repeatedly claimed without substantiation that the other side is planning to provoke an incident involving nuclear, chemical or biological agents," notes CNN.

On Wednesday, Russian's foreign ministry claimed that the U.S. operates a biowarfare lab in Ukraine, "an accusation that has been repeatedly denied by Washington and Kyiv," reports Reuters.

An anonymous reader quotes a report from Ars Technica: Pacific Gas and Electric (PG&E) will begin testing bidirectional charging in California with new pilot programs announced this week at General Motors and Ford. ["This will enable power to flow from a charged EV into a customer's home, automatically coordinating between the EV, home and PG&E's electric supply," explains InsideEVs.] [...] General Motors might be late to the EV pickup party, but on Wednesday, it was first to announce that it is working with PG&E on vehicle-to-home technology. This summer, the two companies will begin lab tests with different GM EVs before starting to test vehicle-to-home connections at some customer homes. The two companies say they plan to open up to a larger customer trial by the end of this year.

On Thursday, Ford and PG&E revealed similar plans at the CERAWeek conference in Houston. Few details have been made public so far, though we know that unlike in the GM pilot, PG&E will not be able to remotely operate the vehicle-to-home feature on demand. And unfortunately, neither the Ford Mustang Mach-E nor the e-Transit will be capable of bidirectional charging; it will just be the F-150 Lightning.

An anonymous reader quotes a report from Motherboard: A company that plans to drill deeper into Earth than ever before, creating holes that would extend a record-shattering 12 miles under our planet's surface, has raised a total of $63 million since its launch in 2020. Most recently, Quaise Energy, a startup that aims to revolutionize the geothermal energy market, secured $40 million in series A funding in February, reports Axios. The goal of these super-deep holes is to access a limitless amount of renewable energy from the heat deep inside Earth.

"This funding round brings us closer to providing clean, renewable baseload energy," said Carlos Araque, CEO and co-founder of Quaise Energy, according to BusinessWire. "Our technology allows us to access energy anywhere in the world, at a scale far greater than wind and solar, enabling future generations to thrive in a world powered with abundant clean energy." Geothermal energy has a low profile compared to other renewable energy sources such as solar, wind, and hydro, but Quaise believes it is "at the core of an energy-independent world," according to the company's website. This form of energy is among the oldest power sources harnessed by humans, but it only accounts for about 0.4 percent of net energy production in the United States, which is the world's biggest geothermal producer.

Quaise, which is a spinoff from the Massachusetts Institute of Technology (MIT), intends to pioneer this technology using vacuum tubes known as gyrotrons that shoot millimeter-wave light beams, powered by electrons in a strong magnetic field. Using these devices, the company plans to burn almost twice as far into Earth as the deepest holes ever made, such as Russia's Kola Superdeep Borehole or Qatar's Al Shaheen oil well, both of which extend for about 7.5 miles. Gyrotrons are powerful enough to heat plasma in nuclear fusion experiments, making them an ideal tool to probe unprecedented depths of some 12 miles, where subterranean rocks roil at temperatures of about 500C (930F). Water pumped into this searing environment would instantly vaporize as steam that could be efficiently converted to electricity. Araque and his team at Quaise plan to funnel their seed money into prototype technologies within the next few years. By 2028, the company aspires to retrofit coal-fueled power plants into geothermal energy hotspots, reports ScienceAlert. The process of drilling out these super-deep holes would take a few months, but once the setup is complete, they could provide limitless energy to a region for up to a century, according to Araque.

China exported nearly 500,000 electric cars in 2021 -- more than any other country in the world -- thanks to increasing sales in Europe and Southeast Asia by emerging cost-competitive automakers, Nikkei has learned. From the report: According to the General Administration of Customs of China, the number of passenger EVs exported in 2021 increased 2.6 times to 499,573 units. Meanwhile, Germany doubled its exports to about 230,000 units, while the U.S fell 30% to around 110,000 units, and Japan increased 24% to 27,400 units -- according to data compiled by the German Association of the Automotive Industry and the Japan External Trade Organization.

China accounts for 60% of global EV production, and is emerging as the world's factory for EVs having already secured the same position in digital product manufacturing. Exports to the EU grew in the wake of it announcing a policy to ban the sale of new hybrid and gasoline-powered vehicles in 2035. China's EV exports to Europe rose fivefold to 230,000 units, with the region absorbing half of China's total EV exports. Belgium imported 87,000 units and the U.K. 50,000 units. Of the almost 500,000 units exported, more than 100,000 appear to have originated from Tesla's Shanghai plant.

On February 24, Russian forces seized control of the Chernobyl nuclear plant and took its staff hostage, causing radiation levels to increase about 20-fold from all the heavy military vehicles stirring contaminated soil in the exclusion zone surrounding the plant. Today, the Ukrainian government warned that the abandoned nuclear power plant, including other nuclear facilities nearby, no longer have electricity after a power line was damaged. Axios reports: A loss of power at the plant could disrupt the cooling of radioactive material stored there, risking radioactive leakage that can be carried by wind to other parts of Europe. [...] "About 20,000 spent fuel assemblies are stored in the spent nuclear fuel storage facility-1. They need constant cooling, which is possible only if there is electricity. If it is not there, the pumps will not cool. As a result, the temperature in the holding pools will increase," the Ukrainian government said. "After that evaporation will occur, that will lead to nuclear discharge. The wind can transfer the radioactive cloud to other regions of Ukraine, Belarus, Russia and Europe. In addition, there is no ventilation inside the facility," it added.

The International Atomic Energy Agency said Wednesday that Ukraine had informed it of the power outage and called it a violation of a "key safety pillar" but saw "no critical impact on safety" in this case. The agency's director general said Tuesday that it was no longer receiving data monitoring systems installed at the plant and other facilities and that the handling of nuclear material in the Chernobyl Exclusion Zone had been put on hold. "I'm deeply concerned about the difficult and stressful situation facing staff at the Chernobyl nuclear power plant and the potential risks this entails for nuclear safety. I call on the forces in effective control of the site to urgently facilitate the safe rotation of personnel there," IAEA director general Rafael Mariano Grossi said Tuesday.

The Ukrainian government is preparing for the potential need to move its data and servers abroad if Russia's invading forces push deeper into the country, a senior cybersecurity official told Reuters on Wednesday. From the report: Victor Zhora, the deputy chief of Ukraine's State Service of Special Communications and Information Protection, emphasized his department was planning for a contingency, but that it is being considered at all suggests Ukrainians want to be ready for any Russian threat to seize sensitive government documents. The move could only happen after regulatory changes approved by Ukrainian lawmakers, Zhora said.

Government officials have already been shipping equipment and backups to more secure areas of Ukraine beyond the reach of Russian forces, who invaded on Feb. 24 and are laying siege to several cities. Last month Zhora told Politico there were plans to move critical data out of the capital Kyiv should it be threatened, but preparations for potentially moving data abroad go a step further. Ukraine has received offers to host data from a variety of countries, Zhora said, declining to identify them. For reasons of proximity "a European location will be preferred," he said.

Zhora gave few details of how such a move might be executed, but he said past efforts to keep government data out of Russia's grasp involved either the physical transport of servers and removable storage devices or the digital migration of data from one service or server to another. Government agencies would have to decide on a case by case basis whether to keep their operations running inside the country or evacuate them. [...] Russia possessing Ukrainian government databases and intelligence files could be helpful if Russia wanted to control Ukraine.

At its "Peek Performance" event, Apple today announced the third-generation iPhone SE, featuring the A15 Bionic chip, improved battery life, 5G connectivity, a new camera system, and more, all for a starting price of $429. MacRumors reports: The new iPhone SE features the same 4.7-inch display as the current model, but now offers the toughest glass in a smartphone on the front and back -- the same as on the back of the iPhone 13 and iPhone 13 Pro. The device's new 12MP Wide camera system offers a range of improvements and computational photography features including Deep Fusion, Photographic Styles, Portrait Mode, and Smart HDR 4.

The new iPhone SE contains the same A15 Bionic chip from the iPhone 13 and iPhone 13 Pro. [...] The A15 Bionic also gives the new iPhone SE longer battery life than the previous-generation and older 4.7-inch iPhone models despite having a compact form-factor and 5G connectivity. It continues to support fast charging and be compatible with Qi-certified chargers for wireless charging. Along with the new iPhone SE, Apple also unveiled the all-new Mac Studio and Studio Display, flagship M1 Ultra desktop processor, and updated iPad Air.

The next generation of Apple Silicon chips has arrived with the announcement of the company's new M1 Ultra SoC (system on a chip), the latest entry to Apple's M1 chipset lineup that's even more powerful than the M1, M1 Pro, and M1 Max chips its released so far. From a report: The key to the M1 Ultra is the Apple's UltraFusion architecture -- effectively, Apple is fusing together two separate M1 Max chips into a single, massive SoC, thanks to the 2.5TB/s inter-processor connection that the M1 Max offers. That design lets Apple double virtually all the specs from its M1 Max chip on the M1 Ultra: 20 CPU cores (16 performance and four efficiency), 64 GPU cores, a 32-core Neural Engine for AI processing, and up to 128GB of RAM. All told, Apple says that the M1 Ultra offers eight times the performance of the regular M1.

Laptops and smartphones made by Apple, Microsoft, and Google are considerably less repair-friendly than those made by competitors Asus, Dell, and Motorola, according to a new report. From a report: These findings may be unsurprising to people who like to fix gadgets, but the data to back them up comes from an unusual source: the companies themselves. The report, released today by the US Public Research Interest Group's Education Fund, draws on data companies are now releasing in France to comply with the government's world-first "repairability index" law, which went into effect last year. The law requires manufacturers of certain electronic devices, including cell phones and laptops, to score each of their products based on how easily repairable it is and make that score, along with the data that went into it, available to consumers at point-of-sale.

An anonymous reader quotes a report from Interesting Engineering: Green Hydrogen International (GHI) has unveiled its plans to build a 60 GW green hydrogen production facility near the Piedras Pintas salt dome in Texas. The facility will be the largest of its kind in the world, the company claimed in a press release. While the world seeks cleaner alternatives to the energy that can power long-haul flights and stand in as a substitute for natural gas, green hydrogen appears to be one of the front runners. With countries such as China, Saudi Arabia, Chile, Spain having initiated green hydrogen projects on a pilot basis, GHI would have to make a big splash to announce its arrival.

The company is hopeful that its proposed plant, capable of producing 2.5 billion kilograms of green hydrogen every year, will do exactly that. According to its website, GHI has seven projects that are under development with a combined output of one terawatt. The largest and the first one to get off the ground is Hydrogen City in Texas. Using onshore wind and solar energy, the project aims to produce 60 gigawatts of green hydrogen every year. The Piedras Pintas salt dome in Duval County will serve as the hydrogen storage facility for the project which in its initial stages will see a 2-gigawatt production facility being drawn up. Green hydrogen production is expected to begin by 2026 and it will tap into renewable energy from the Texan electricity grid. Green hydrogen produced at the facility will be piped to the coastal city of Corpus Christi and Brownsville, where industries will convert them to other products. "Hydrogen City is a massive, world-class undertaking that will put Texas on the map as a leading green hydrogen producer," GHI's founder and CEO Brian Maxwell said. "Texas has been the world leader in energy innovation for over 100 years and this project is intended to cement that leadership for the next century and beyond."

A research center housing a nuclear neutron source facility held at the Kharkiv Institute of Physics and Technology in eastern Ukraine was hit by Russian forces on Sunday, per a report from the state nuclear inspectorate. Motherboard reports: In a release published Sunday evening, the inspectorate called the blast "nuclear terrorism," spelling out a list of damages: a substation, which connects the plant to the electrical grid, on which the plant runs; cables within the facility's cooling system, which effectively prevent the plant from a meltdown; a heating line between structures in the facility; surface damages to the building that houses the structure; and windows across a number of buildings within the installation. "This list of damages is not complete so far. Currently, information on the consequences of the damages is being specified by the personnel," the report reads. An updated report following further inspection located no additional damage this morning.

The Security Service of Ukraine's Kharkiv branch said destruction of the facility could lead to "environmental disaster," the Kyiv Independent reported Sunday. Russian state-owned news agency TASS reported Sunday that the attacks were in fact brought on by Ukraine, a line that has since been debunked. The reactor, known as the NSA "Neutron Source" was built with support from the Illinois-based Argonne National Laboratory in service of an agreement signed between the U.S. and Ukraine at the 2010 Nuclear Security Summit in Washington, D.C. The U.S. invested $73 million in the project, which promised that the Kharkiv Institute of Physics and Technology would be "given the opportunity to build state-of-the-art technology in nuclear research that will contribute to "solving problems of nuclear power industry and extending technical lifetime of nuclear power plants,'" according to a report from the European Union Non-Proliferation Consortium.

NBC News reports that energy analysts "still expect most solar energy production in the near future to come from utility-scale projects, in part because of the savings that comes with massive installations."

Unfortunately, "It's those projects that are facing pushback." Local governments in states such as California, Indiana, Maine, New York and Virginia have imposed moratoriums on large-scale solar farms, as a national push for cleaner energy has collided with complaints about how the projects affect wildlife and scenic views. In one Nevada town west of Las Vegas, residents are trying to block a proposed 2,300-acre solar field. NBC News counted 57 cities, towns and counties across the country where residents have proposed solar moratoriums since the start of 2021, according to local news reports, and not every proposed ban gets local news coverage. At least 40 of those approved the measures. Other localities did so in earlier years.

That resistance is a threat to the big ambitions of the solar energy movement.
The current workaround? Solar panel installations "in unexpected places..." [Walmart] told NBC News it has more than 550 renewable energy projects, including solar and wind, implemented or under development. Several have opened recently in California, including with parking lot canopies. The company has a goal of using 100 percent renewable energy by 2035, up from 36 percent by its estimate now....

Houston has chosen the 240-acre site of a former landfill to install what the city said will be the largest infill solar project in the nation. In a neighborhood named Sunnyside, the project will generate enough electricity for 5,000 homes, according to the city. Similar projects have been built on landfills throughout New Jersey. An energy firm is building a solar project on a former coal mine on the border of Kentucky and West Virginia, while in New York state, researchers at Cornell University are testing putting solar panels in a field where sheep graze.

A city in Northern California says it has the largest floating solar farm in the U.S. at its wastewater treatment plant, and in January, a China-based energy company said it had built the world's largest floating solar array on a reservoir there. And last year, the Biden administration encouraged the development of solar projects on highway right-of-way, with a notice from the Federal Highway Administration telling field offices to work with states on ideas. Researchers at the University of Texas at Austin, including Webber, have said most states have more than 200 miles of interstate frontage suitable for solar development, especially near exits and rest stops.

Creative locations have a particular benefit: fewer potential neighbors who might complain.

"Every day, several petabytes of data are generated on the internet," says Kasra Tabatabaei, a researcher at the Beckman Institute for Advanced Science and Technology. "Only one gram of DNA would be sufficient to store that data."

So the Institute is now announcing the results of a project Tabatabaei worked on "to transform the double helix into a robust, sustainable data storage platform." CNET reports: Tabatabaei is the co-author of a new study, published in last month's edition of the journal Nano Letters... Essentially, the study team is the first to artificially extend the DNA alphabet, which could allow for massive storage capacities and accommodate a pretty extreme level of digital data.... DNA encodes genetic information with four molecules called nucleotides. There's adenine, guanine, cytosine and thymine, or A, G, C and T. In a sense, DNA has a four-letter alphabet, and different letter combinations represent different bits of data....

But what if we had a longer alphabet? Presumably, that'd give us a much deeper capacity. Following this line of thought, the team behind the new study artificially added seven new letters to the DNA repertoire.... "Instead of converting zeroes and ones to A, G, C and T, we can convert zeroes and ones to A, G, C, T and the seven new letters in the storage alphabet."
One of the study's co-principal investigators said their work "provides an exciting proof-of-principle demonstration of extending macromolecular data storage to non-natural chemistries, which hold the potential to drastically increase storage density in non-traditional storage media."

"The future of the nuclear power industry is being pushed on both by climate change and security fears stoked by Russia invading Ukraine and targeting the Zaporizhzhia nuclear power plant," reports CNBC, with the world's nations "coming to realize they can't meet their climate goals with renewables, like wind and solar, alone." Kenneth Luongo, founder of the security/energy nonprofit Partnership for Global Security, even tells CNBC there was a "sea change" in sentiment toward nuclear power at the 2021 United Nations Climate Change Conference. There are about 440 nuclear power reactors operating in more than 30 countries that supply about 10% of the world's electricity, according to the World Nuclear Association. Currently, 55 new reactors are being constructed in 19 countries, and 19 of those are in China. The U.S. only has two underway.... Currently, three new nuclear reactors are being built in Russia. But Russia is also the world's top nuclear technology exporter....

As Russia and China have risen to prominence, the United States has lost "the muscle memory" to build conventional nuclear reactors, Luongo said. Nuclear power got a poor reputation in the United States after the nuclear accident at Three Mile Island in 1979 in Pennsylvania, and more globally after the accidents at Chornobyl in the Ukrainian Soviet Union in 1986 and Fukushima in Japan in 2011. But the tide is starting to turn. The Biden administration's solution was included in the Bipartisan Infrastructure Law, which was signed into law November, and was effectively a big subsidy. The law includes a $6 billion program intended to preserve the existing U.S. fleet of nuclear power reactors.... At the same time, the Russia-Ukraine war gives the United States leverage to pry open more of a footprint in the global market. While the war is tragic, "it's going to result in more opportunity for U.S. nuclear firms as Russia really disqualifies itself," said John Kotek of the Nuclear Energy Institute [a U.S. nuclear industry trade association]. Russia's dangerous attack at Zaporizhzhia nuclear power plant in Ukraine and China's decision to not vote in favor of the IAEA's resolution to prevent the kind of attack "will blowback on both countries' nuclear export reputation," Luongo told CNBC....

Nuclear plants are expensive to build and have, in many places, become more expensive than other baseload energy alternatives like natural gas. However, the U.S. is pushing hard into what could become the next generation of nuclear. "The United States has made a decision that they don't want to allow Russia and China to dominate that next phase of the nuclear market. And so the U.S. is pouring billions of dollars — shockingly — billions of dollars into the development of what are called small modular reactors," Luongo said. Specifically, the government is using the Idaho National Lab as a testing ground for these reactors.
Without specifically mentioning nuclear energy, former Gawker editor Alex Pareene recently argued a program of "mass electrification and renewable energy" could diminish the power of "oligarchic petrostates."

"Staff at Ukraine's Zaporizhzhia nuclear power plant are being told what to do by the Russian military commander who seized the site last week, in violation of international safety protocols," reports the Guardian: The International Atomic Energy Agency (IAEA) expressed "grave concern" at the situation at the six-reactor plant, the largest in Europe. The agency was told by the Ukrainian nuclear regulator that "any action of plant management — including measures related to the technical operation of the six reactor units — requires prior approval by the Russian commander". The IAEA director general, Rafael Mariano Grossi, said on Sunday that the Russian military command over the nuclear plant "contravenes one of the seven indispensable pillars of nuclear safety and security" which states that the operating staff must be able to carry out their safety and security duties and be able to make decisions "free of undue pressure".

Russian forces shelled the Zaporizhzhia plant in the early hours of Friday morning, damaging a walkway between two of the six reactors, and starting a fire in a nearby building used for training. As a result some of the reactors were shut down and others were put on low power. The reactors themselves are well protected by a thick concrete shell, but there is concern that more vulnerable spent fuel rods could be hit, or that the power and cooling systems could be affected, potentially triggering a meltdown....

The IAEA said that the operators at the plant were now being able to rotate between three shifts, relieving the operators who had been on duty at the time the plant was seized, but there were still "problems with availability and supply of food" which the Ukrainian regulator said was affecting morale on the plant.
