Vast Swath of US At Risk of Summer Blackouts, Regulator Warns (newsnationnow.com) 195

An anonymous reader quotes a report from NewsNation: Blackouts could plague a number of states in the U.S. this summer, regulators warn, as a combination of drought, heat, potential cyber attacks, geopolitical conflicts and supply chain problems could disrupt the power supply, according to a grim new report (PDF) from the North American Electric Reliability Corporation (NERC). The regulatory body found that large swathes of the U.S. and parts of Canada are at an elevated or high risk of energy shortfalls during the summer's hottest months.

The Midwest is at especially high risk due to the retirement of older plants, which has caused a 2.3% decrease in capacity from last summer, as well as increased demand, according to NERC. In the Southwest, plummeting river levels may cripple hydropower production, the group warned, and in Texas drought-related heat events could cause extreme energy demand. A NERC map shows all states in the western half of the continental U.S., including North Dakota, South Dakota, Nebraska, Kansas, Oklahoma and Texas are at least under elevated risk of energy shortfalls, with parts of the northeastern-most states under high risk. Many states under the Midcontinent Independent System Operator (MISO), such as Arkansas, Louisiana, Michigan, Wisconsin, Iowa, Minnesota, Iowa, Illinois and Indiana are either entirely or partly at high risk.
"Industry prepares its equipment and operators for challenging summer conditions. Persistent, extreme drought and its accompanying weather patterns, however, are out-of-the-ordinary and tend to create extra stresses on electricity supply and demand," said Mark Olson, NERC's manager of Reliability Assessments. "Grid operators in affected areas will need all available tools to keep the system in balance this summer."

Solar-Powered Desalination Device Wins MIT $100K Competition (mit.edu) 77

The winner of this year's MIT $100K Entrepreneurship Competition is commercializing a new water desalination technology. MIT News reports: Nona Desalination says it has developed a device capable of producing enough drinking water for 10 people at half the cost and with 1/10th the power of other water desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar panel. The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT's Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current.

"Because we can do all this at super low pressure, we don't need the high-pressure pump [used in reverse osmosis], so we don't need a lot of electricity," says Crawford, who co-founded the company with MIT Research Scientist Junghyo Yoon. "Our device runs on less power than a cell phone charger." The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers. The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil and gas separation, and more.

China Chipmaker SMIC Says Phone, PC Demand Has Dropped 'Like a Rock' (nikkei.com) 24

Top Chinese chipmaker Semiconductor Manufacturing International Co. says demand for mobile phones, personal computers and home appliances has dropped "like a rock" and shows no signs of recovering. From a report: Speaking to investors on Friday, CEO Zhao Haijun said the Russia-Ukraine war and China's COVID lockdowns have massively dented demand for consumer electronics and home appliances, which in turn has led to a "serious" adjustment in chip orders for those segments. "Many smartphone, PC and home appliance companies had exposure in Russia and Ukraine, and their revenues [from those markets] are now gone. Sales in their home market [of China] have also fallen due to the COVID situation domestically," Zhao said.

"We cannot yet see an end to the downtrends in these segments," Zhao added. "There are at least 200 million units of smartphones that will disappear suddenly this year and the majority of them are from our domestic Chinese phone makers." Demand for consumer electronics "dropped like a rock, very seriously," the executive said. "Some of our customers are holding more than five months of that type of inventory." However, Zhao said SMIC's factories are still running at 100% capacity, as the company has been allocating resources to products that are still in great shortage, such as power management chips and microcontrollers used in green energy, electric vehicles and industrial applications.

Report: 'Nvidia's LHR Limiter Has Fallen, But Gamers Shouldn't Worry' (tomshardware.com) 46

Slashdot reader Hmmmmmm shared this report from Hot Hardware: When Nvidia launched its Ampere Lite Hash Rate (LHR) graphics card with the feared Ethereum anti-mining limiter, the world knew it was only a matter of time before someone or a team cracked it. NiceHash, the company that designed the QuickMiner software and Excavator miner, has finally broken Nvidia's algorithm, restoring LHR graphics cards to their 100% Ethereum mining performance....

Graphics card pricing has been plummeting, and we're starting to see better availability at retailers, with some GPUs selling at or below Manufacturer Suggested Retail Price. So QuickMiner's arrival shouldn't influence the current state of the graphics market unless big corporations want to buy out everything in sight for the last push before Ethereum's transition to Proof-of-Stake (PoS), often referred to as "The Merge," is complete. We see that as unlikely, considering current profitability even on a 3080 Ti sits at around $3.50 per day and would still need nearly a year to break even at current rates. Initially scheduled for June, The Merge won't finalize until "the few months after," as Ethereum developer Tim Beiko has expressed on Twitter.

It will be interesting to see if Nvidia responds to this with updated drivers or implements LHRv3 in the remaining GPUs. However, it's perhaps not worth the effort at this point, and all existing LHRv2 and earlier cards can just stay on current drivers for optimized mining performance.

Facing High Demand, Texas Asks 26 Million to Use Less Electricity This Weekend (cnn.com) 240

Friday a heat wave hit Texas — prompting the non-profit that manages power for Texas's 26 million customers to...ask them to use less of it.

"The Electric Reliability Council of Texas (ERCOT) made the appeal in a statement Friday, saying that soaring temperatures increased demand and caused six power generation facilities to trip offline," reports CNN. "That resulted in the loss of about 2,900 megawatts of electricity."

The statement asks Texans "to conserve power when they can by setting their thermostats to 78-degrees or above and avoiding the usage of large appliances (such as dishwashers, washers and dryers) during peak hours between 3 p.m. and 8 p.m. through the weekend." CNN reports: The appeal comes as record temperatures across most of the southern U.S. this weekend are expected to worsen a deepening drought. From Phoenix to Amarillo, Texas, record temperatures are expected to reach triple digits, with a chance for some parts of Texas to break daily records over the next seven days.

ERCOT came under scrutiny last year after record cold temperatures in February caused the state's highest electricity demand and more than 200 people died during the power crisis, with the most common cause of death being hypothermia. In March 2021, ERCOT's president and CEO, Bill Magness, was fired following widespread power outages during a series of winter storms that left many residents in the dark for days. Now the heat is testing Texas' power grid....

Temperatures from the mid-90s to the low 100s are expected on Sunday, with much of central and western Texas reaching 100 to 105 degrees — approximately 10 to 15 degrees above average.

Nuclear Energy: the Case Against (theguardian.com) 362

"We do not need to plunge headlong into a nuclear future," argues Serhii Plokhy, author of the book Atoms and Ashes: From Bikini Atoll to Fukushima.

He notes Belgium's adding a 10-year extension to the life of two of its nuclear reactors, France's program to build 14 new reactors, and Boris Johnson's pledge to create supply 25% of the UKs power needs with nuclear energy by 2050. On the surface, the switch to nuclear makes sense. It would not only enable European countries to meet their ambitious net zero targets, since it produces no CO2. It would also make them less vulnerable to Russian threats, and allow them to stop financing the Russian war machine....

What the Russian takeover of [Ukraine] nuclear facilities exposed is a hazard inherent in all nuclear power. In order for this method of producing electricity to be safe, everything else in society has to be functioning perfectly. Warfare, economic collapse, climate change itself — all of these increasingly real risks make nuclear sites potentially perilous places. Even without them, the dangers of atomic fission remain, and we must ask ourselves: are they really worth the cost...?

Technological developments, growing international cooperation and rising safety standards did indeed do a great deal to ensure that no major nuclear accident occurred for 25 years after Chernobyl. But the Fukushima explosions demonstrated that such improvements have not eradicated the dangers surrounding nuclear power plants.... Can anything be done to make reactors safer? A new generation of smaller modular reactors, designed from scratch to produce energy, not to facilitate warfare, has been proposed by Bill Gates, and embraced, among others, by Macron. The reactors promised by Gates's TerraPower company are still at the computer-simulation stage and years away from construction. But his claim that in such reactors "accidents would literally be prevented by the laws of physics" must be taken with a pinch of salt, as there are no laws of war protecting either old or new reactors from attack.

There is also serious concern that the rapid expansion in the number of plants, advocated as a way of dealing with climate change, will increase the probability of accidents. While new technology will help to avoid some of the old pitfalls, it will also bring new risks associated with untried reactors and systems. Responsibility for dealing with such risks is currently being passed on to future generations.

This is the second great risk from nuclear power: even if a reactor runs for its lifetime without incident, you still have a lot of dangerous material left at the end of it. Fuel from nuclear power plants will present a threat to human life and the environment for generations to come, with the half-life of some radioactive particles measured in tens of thousands of years.... Nuclear power plants generally have no alternative to storing their high-level radioactive waste on site....If what we bury today in the New Mexico desert — the waste created by our nuclear ambitions — is so repulsive to us, why do we pass it on to others to deal with?

The author's counter-proposal: expanding the use of renewable energy: New research should be encouraged, grid infrastructure should be built up, and storage capacity increased. Billions that would otherwise go to new nuclear infrastructure, with all the attendant costs of cleanup that continue for decades and beyond, should be pumped instead into clean energy.

In the meantime, we obviously have an existing nuclear industry, and the solution is not to run away in panic, but to take good care of the facilities that already dot our countryside. We must not abandon the industry to its current state of economic hardship, as that would only mean inviting the next accident sooner rather than later.

Samsung Is Reportedly Planning To Raise Chip Prices By 20% (pcmag.com) 28

Samsung is currently considering raising the cost of its semiconductor products by up to 20%, as well as those it manufactures for other companies, which would ultimately lead to consumers paying more for new devices. PC Magazine reports: As Bloomberg reports, the price hike consideration is in response to just about everything in the world getting more expensive, including the cost of raw materials and the logistics surrounding production pipelines. The final price increase is expected to be linked to sophistication of the components being manufactured, but that still means vendors will end up paying between 15-20% more for chips. Samsung is a huge player in the semiconductor industry, producing processors for a wide-range of industries, as well as memory products, storage solutions, and foundry solutions which allow other semiconductor products to be manufactured. Adding up to a 20% price rise across all those sectors will inevitably push up prices for any products that use Samsung components.

A Colony of Blue-Green Algae Can Power a Computer For Six Months (interestingengineering.com) 49

An anonymous reader quotes a report from Interesting Engineering: Researchers from the University of Cambridge have managed to run a computer for six months, using blue-green algae as a power source. A type of cyanobacteria called Synechocystis sp. PCC 6803 -- commonly known as "blue-green algae," which produces oxygen through photosynthesis when exposed to sunlight, was sealed in a small container, about the size of an AA battery, made of aluminum and clear plastic.

Christopher Howe from the University of Cambridge and colleagues claim that similar photosynthetic power generators could be the source of power for a range of small devices in the future, without the need for the rare and unsustainable materials used in batteries. The battery made of blue-green algae has provided a continuous current across its anode and cathode that ran a microprocessor. The computer ran in cycles of 45 minutes. It was used to calculate sums of consecutive integers to simulate a computational workload, which required 0.3 microwatts of power, and 15 minutes of standby, which required 0.24 microwatts. The microcontroller measured the device's current output and stored this data in the cloud for researchers to analyze.

Howe suggests that there are two potential theories for the power source. Either the bacteria itself produces electrons, which creates a current, or it creates conditions in which an aluminum anode in the container is corroded in a chemical reaction that produces electrons. The experiment ran without any significant degrading of the anode and because of that, the researchers believe that the bacteria is producing the bulk of the current. Howe says that the approach could be scaled up, but further research is needed to figure out how far.
The research was published in the journal Energy & Environmental Science.

Scientists Discover Unexplained Abundance of Rare Nuclear Fusion Fuel on Earth (vice.com) 87

An anonymous reader quotes a report from Motherboard: Scientists have discovered evidence that a key rare resource, called helium-3, is potentially ten times more common on Earth than previously known -- though the source of all this extra supply remains mysterious, reports a new study. The finding is important because helium-3 could serve as a foundation of limitless clean power for our civilization, but has been seen as inaccessible since it is largely found in outer space locations, especially the Moon. Helium-3 is an isotope of helium, which means it contains the same number of protons as this common element but a different number of neutrons. This isotope is considered a potentially powerful energy source for future fusion reactors, making it a star of science fiction as well as a sought-out resource in the real world. However, while small amounts of the substance are produced by geological processes and from the fallout of nuclear weapons testing, there is thought to be very little helium-3 available on Earth.

Now, scientists led by Benjamin Birner, a postdoctoral scholar in geosciences at the University of California San Diego, have captured evidence for a previously unknown abundance of helium-3 in the atmosphere, which "presents a major puzzle in the helium-3 budget" and "motivates a search for missing helium-3 sources on Earth, especially since helium-3 is considered an important, yet scarce, resource," according to a study published on Monday in Nature Geoscience. Known sources of helium-3 on Earth only account for 10 percent of the surplus, the researchers said. Birner and his colleagues serendipitously uncovered this inferred surplus of helium-3 (3He) while tackling another challenging problem: measuring the overall rise in atmospheric helium as a result of human consumption of fossil fuels. The team pioneered a first-of-its-kind technique for estimating these anthropogenic helium emissions by examining another isotope, helium-4 (4He), which in turn led to the perplexing conclusion that there is some unknown source of helium-3 on our planet. "We only measured the change in atmospheric 4He," Birner said in an email. "However, previous work by other researchers indicates that the helium isotopic ratio of the atmosphere (3He/4He) is roughly stable. Together these observations imply an increase in atmospheric 3He that matches the rise in 4He or we would see a change in the atmospheric isotope ratio."

Helium-3 could be the ideal fuel for nuclear fusion, a potential energy source that mimics the same process that powers stars. Though nuclear fusion may not materialize as a practical power source for decades, assuming it is feasible at all, its potential to provide clean and limitless energy to the global human population makes it a tantalizing area of study. To that end, scientists across fields are likely to be interested in locating this unexplained surplus of helium-3 on Earth that has been implied by the new research. "That increase of 3He is quite puzzling because we don't have a good explanation for the source of this 3He so far," Birner noted. "It's quite an important puzzle to solve also because 3He is an important and scarce resource for nuclear fusion reactors. Based on the reported uncertainties in previous studies of the atmospheric 3He/4He trend, the buildup of 3He looks significant, but our study clearly motivates a closer look at the atmospheric 3He/4He trend."

California Energy Officials Warn of Possible Blackouts This Summer For Up To 4M (usnews.com) 112

Reuters reports: California energy officials on Friday issued a sober forecast for the state's electrical grid, saying it lacks sufficient capacity to keep the lights on this summer and beyond if heatwaves, wildfires or other extreme events take their toll....

California has among the most aggressive climate change policies in the world, including a goal of producing all of its electricity from carbon-free sources by 2045. In an online briefing with reporters, the officials forecast a potential shortfall of 1,700 megawatts this year, a number that could go as high as 5,000 MW if the grid is taxed by multiple challenges that reduce available power while sending demand soaring, state officials said during an online briefing with reporters. Supply gaps along those lines could leave between 1 million and 4 million people without power.

Outages will only happen under extreme conditions, officials cautioned, and will depend in part on the success of conservation measures.

Giving Old Dams New Life Could Spark an Energy Boom (msn.com) 50

"Extreme drought has drastically reduced reservoir levels and is causing a decline in electricity production from hydropower," reports the Washington Post.

"Yet while climate change has parched the West, these same forces have greatly increased precipitation in much of the Midwest, the South and the East. There, hydropower is gaining momentum, and supporters say that in many places it is poised for a big resurgence." And the Post sees this benefiting "a growing effort to retrofit so-called nonpowered dams, or any dams created for a need other than hydropower, for electricity production..." In 2016, a U.S. Department of Energy study forecast that hydropower in the United States could expand from its current capacity of 101 gigawatts to nearly 150 gigawatts by 2050. This growth would come not from new dam construction but from upgrading existing hydroelectric resources, adding pumped storage capacity, and retrofitting nonpowered dams for hydropower.... Nonpowered dams compose the vast majority of America's dam infrastructure. They can be found across the country, come in all sizes and were built to address a wide array of needs, including flood control, navigation, water supply and recreation.

Out of the estimated 90,000 dams in the United States, about 2,200 of them generate hydroelectric power. These hydropower resources, however, account for 7 percent of national energy production and contribute 37 percent of the nation's renewable energy supply....

Solar and wind produce energy intermittently, but hydropower can operate day or night, 24/7. Some hydropower facilities can shut down or ramp up energy production very quickly, providing energy grids with stopgap flexibility during peak demand or in the case of blackouts.... The addition of hydropower to nonpowered dams can be financially attractive to developers. Typically the dam's operation is not changed, so there is usually much less opposition from communities and environmental groups than there would be to a new dam project.

The article points out that last year's U.S. infrastructure funding included money to add hydropower to "nonpowered dams."

Rechargeable Molten Salt Battery Freezes Energy In Place For Long-Term Storage (scientificamerican.com) 40

An anonymous reader quotes a report from Scientific American: During spring in the Pacific Northwest, meltwater from thawing snow rushes down rivers and the wind often blows hard. These forces spin the region's many power turbines and generate a bounty of electricity at a time of mild temperatures and relatively low energy demand. But much of this seasonal surplus electricity -- which could power air conditioners come summer -- is lost because batteries cannot store it long enough. Researchers at Pacific Northwest National Laboratory (PNNL), a Department of Energy national laboratory in Richland, Wash., are developing a battery that might solve this problem. In a recent paper published in Cell Reports Physical Science, they demonstrated how freezing and thawing a molten salt solution creates a rechargeable battery that can store energy cheaply and efficiently for weeks or months at a time.

Most conventional batteries store energy as chemical reactions waiting to happen. When the battery is connected to an external circuit, electrons travel from one side of the battery to the other through that circuit, generating electricity. To compensate for the change, charged particles called ions move through the fluid, paste or solid material that separates the two sides of the battery. But even when the battery is not in use, the ions gradually diffuse across this material, which is called the electrolyte. As that happens over weeks or months, the battery loses energy. Some rechargeable batteries can lose almost a third of their stored charge in a single month.

"In our battery, we really tried to stop this condition of self-discharge," says PNNL researcher Guosheng Li, who led the project. The electrolyte is made of a salt solution that is solid at ambient temperatures but becomes liquid when heated to 180 degrees Celsius -- about the temperature at which cookies are baked. When the electrolyte is solid, the ions are locked in place, preventing self-discharge. Only when the electrolyte liquifies can the ions flow through the battery, allowing it to charge or discharge. Creating a battery that can withstand repeated cycles of heating and cooling is no small feat. Temperature fluctuations cause the battery to expand and contract, and the researchers had to identify resilient materials that could tolerate these changes. [...] The result is a rechargeable battery made from relatively inexpensive materials that can store energy for extended periods.
"Right now the experimental technology is aimed at utility-scale and industrial uses," notes the report. "The PNNL team plans to continue developing the technology, but ultimately it will be up to industry to develop a commercial product."

Swarming Drones Autonomously Navigate a Dense Forest (techcrunch.com) 15

Chinese researchers show off a swarm of drones collectively navigating a dense forest they've never encountered. TechCrunch reports: Researchers at Zheijang University in Hangzhou have succeeded, however, with a 10-strong drone swarm smart enough to fly autonomously through a dense, unfamiliar forest, but small and light enough that each one can easily fit in the palm of your hand. It's a big step toward using swarms like this for things like aerial surveying and disaster response.

Based on an off-the-shelf ultra-compact drone design, the team built a trajectory planner for the group that relies entirely on data from the onboard sensors of the swarm, which they process locally and share with each other. The drones can balance or be directed to pursue various goals, such as maintaining a certain distance from obstacles or each other, or minimizing the total flight time between two points, and so on.

The drones can also, worryingly, be given a task like "follow this human." We've all seen enough movies to know this is how it starts ... but of course it could be useful in rescue or combat circumstances as well. A part of their navigation involves mapping the world around them, of course, and the paper includes some very cool-looking 3D representations of the environments the swarm was sent through.

Apple Reaches Settlement To Pay $15 To Some iPhone 4S Owners Over Throttling (macrumors.com) 34

An anonymous reader quotes a report from MacRumors: Apple has agreed to settle a long-lasting six-year class-action lawsuit that accused it of knowingly slowing down iPhone 4S devices following the iOS 9 update in 2015, agreeing to pay some iPhone 4S owners who had experienced poor performance $15 each for their claims. The class-action lawsuit was initially filed in December 2015 by plaintiffs representing a group of iPhone 4S customers from New York and New Jersey. The lawsuit accused Apple of falsely marketing the iOS 9 update as providing enchanted performance on devices it supports, including the iPhone 4S.

Under the settlement, Apple allocated $20 million to compensate iPhone 4S owners in New York and New Jersey who experienced poor performance after updating to iOS 9. Customers who believe they are entitled to the $15 must "submit a declaration under the penalty of perjury that, to the best of their knowledge, they downloaded iOS 9, or any version thereof, onto their iPhone 4S... their iPhone 4S experienced a significant decline in performance as a result, are entitled to a payment of $15 per applicable device." A website will be created where customers who believe they are entitled to the settlement will be able to submit a form, providing their name, email, iPhone 4S serial number (if possible), and mailing address.

AMD Doubles the Number of CPU Cores It Offers In Chromebooks (arstechnica.com) 23

AMD announced the Ryzen 5000 C-series for Chromebooks today. "The top chip in the series has eight of AMD's Zen 3 cores, giving systems that use it more x86 CPU cores than any other Chromebook," reports Ars Technica. From the report: The 7nm Ryzen 5000 C-series ranges from the Ryzen 3 5125C with two Zen 3 cores and a base and boost clock speed of 3 GHz, up to the Ryzen 7 5825C with eight cores and a base clock speed of 2 GHz that can boost to 4.5 GHz. For comparison, Intel's Core i7-1185G7, found in some higher end Chromebooks, has four cores and a base clock speed of 3 GHz that can boost to 4.8 GHz.

On their own, the chips aren't that exciting. They seemingly offer similar performance to the already-released Ryzen 5000 U-series chips. The Ryzen 5000 C-series also uses years-old Vega integrated graphics rather than the upgraded RDNA 2 found in Ryzen 6000 mobile chips, which, upon release, AMD said are "up to 2.1 times faster." But for someone who's constantly pushing their Chromebook to do more than just open a Chrome tab or two, the chips bring potentially elevated performance than what's currently available.

Ireland: Data Centers Now Consuming More Electricity Than Rural Homes (irishtimes.com) 46

According to the Irish Times, citing new figures from the Central Statistics Office, data centers used up a greater share of electricity consumption than rural homes in the State last year. From the report: The overall share of metered electricity consumed by data centers has almost tripled in just six years, from 5 percent in 2015 to 14 percent last year. By comparison, urban homes accounted for 21 per cent of metered electricity consumed in 2021 compared with 12 percent consumed by rural dwellings. The figure for electricity consumption by data centers last year represents an increase of 32 percent in that year.

Data centers consumed 265 per cent more electricity in the three-month period between October and December 2021 compared with the three months between January and March 2015. Total metered electricity consumption increased by 16 per cent over the six years with data centers accounting for the 70 per cent of the increased consumption over that period. The surge in electricity use by data centers has come under scrutiny due to concerns about the State's energy supply and the targeted reduction in carbon emissions to tackle climate change.
"There should be more discussion and more serious consideration of a moratorium [to block the opening of more data centers in order to reduce emissions]," said Dr Patrick Bresnihan, a geography lecturer at Maynooth University.

Allowing electricity consumption by data centers to continue to increase would make it harder for the Government to push policies where it is asking individuals to reduce consumption at a time "when consumption by data centers is so high and clearly just growing," said Dr Bresnihan.
