    Facing Post-Brexit Petrol Shortage, UK Issues Emergency Visas for EU Truck Drivers
    Slashdot reader AleRunner tipped us off to some excitement in the UK: The British government said on Friday it may draft in the army to help deliver gas after shortages caused by a scarcity of truck drivers forced the closure of stations across the country. The haulage industry said there was a shortfall of some 100,000 drivers, and that could also lead to shortages of turkeys and toys this Christmas. Some 25,000 drivers returned to Europe after Brexit, and the pandemic halted the qualification process for new workers... Gas is just the latest thing that people in the U.K. are finding hard to come by after its departure from the European Union. Previously McDonald's has been forced to take milkshakes off the menu, KFC has run short on chicken and supermarket shelves have been left bare. The crisis is already beginning to bite in other areas of life, with 18 percent of adults saying they have been unable to buy essential food items in the past two weeks, according to the U.K.'s Office for National Statistics. The pandemic means that many countries are facing supply chain problems, as manufacturing centers in Asia are hit by continuing cases and restrictions. Now the Associated Press reports the government has decided to issue thousands of emergency visas to foreign truck drivers: Post-Brexit immigration rules mean newly arrived EU citizens can no longer work visa-free in Britain, as they could when the U.K. was a member of the trade bloc. Trucking companies have been urging the British government to loosen immigration rules so drivers can more easily be recruited from across Europe... One cause of the trucker shortage is a backlog caused by the suspension of driver testing for months during Britain's coronavirus lockdowns. The government has already increased testing capacity, as well as extending the number of hours that drivers can work each week, prompting safety concerns. The government said military driving examiners would be pulled in to further boost civilian testing capacity.

    After 47 Years, US Power Company Abandons Still-Unfinished $6 Billion Nuclear Power Plant
    America's federally-owned electric utility, the Tennessee Valley Authority, has spent billions of dollars with nothing to show for it, reports the Chattanooga Times Free Press. "Nearly 47 years after construction began on the Bellefonte Nuclear Power Plant in Northeast Alabama, the Tennessee Valley Authority is giving up its construction permit for America's biggest unfinished nuclear plant and abandoning any plans to complete the twin-reactor facility..." Giving up the construction permit at Bellefonte signals the end of any new nuclear plant construction at TVA with only seven of the 17 nuclear reactors the utility once planned to build ever completed.... Since the 1970s, a total of 95 nuclear reactors proposed to be built by U.S. utilities have been canceled due to rising construction costs, slowing power demand and cheapening power alternatives. The NRC now regulates 93 remaining commercial nuclear reactors at 56 nuclear power plants, including TVA's Sequoyah and Watts Bar nuclear plants in East Tennessee and the Browns Ferry nuclear plant in Athens, Alabama. Collectively, those nuclear plants provide more than 40% of TVA's power and over 20% of the nation's electricity supply... TVA spokesman Jim Hopson said in the past two decades, the growth in power demand in the Tennessee Valley has continued to slow as more energy efficiency measures have been adopted and the price of natural gas, solar power and additional hydroelectric generation has declined in competition with nuclear. Thanks to long-time Slashdot reader The Real Dr John for sharing the story. And today the Chattanooga Times Free Press opinions editor offered this suggestion: TVA still owns the 1,600-acre site, as well as the plant that has never — and likely now will never — generate the first spark of nuclear-produced electricity. But that doesn't mean it can't make power some other way. A gas plant? Uggh. A wind field? Seems unlikely given the stillness of North Alabama. A solar plant? That could be more of a possibility. All of the transmission equipment and the electrical grid is at the ready... By now — after siting, building, scrapping, building again, abandoning, putting up for sale, agreeing to sell for pennies on the dollar and finally going to court to defend not selling the Bellefonte Nuclear Plant — TVA ratepayers and taxpayers have lost somewhere between $6 billion (according to TVA) and $9 billion (according to a 2018 letter from five congressmen)... TVA spokesman Jim Hopson said Wednesday that TVA is making no decisions immediately. "But we're not taking anything off the table," he added... Hopson said TVA's May 2021 "strategic intent and guiding principles" notes the utility has solar commitments to date of more than 2,300 megawatts of solar capacity expected to come online by the end of 2023. Including those projects, TVA expects to add 10,000 megawatts of solar power by 2035 — a 24-fold increase from today. That 10,000 megawatts of solar power would be equal to more than eight would-be Bellefonte reactors.

    Chipmakers To Carmakers: Time To Get Out of the Semiconductor Stone Age
    Long-time Slashdot reader BoredStiff shares this report from Fortune: Moore's law of ever-increasing miniaturization seemingly never reached the automotive industry. Dozens of chips found in everything from electronic brake systems to airbag control units tend to rely on obsolete technology often well over a decade old. These employ comparatively simple transistors that can be anywhere from 45 nanometers to as much as 90 nanometers in size, far too large — and too primitive — to be suitable for today's smartphones. When the pandemic hit, replacement demand for big-ticket items like new cars was pushed back while sales of all kinds of home devices soared. When the car market roared back months later, chipmakers had already reallocated their capacity. Now these processors are in short supply, and chipmakers are telling car companies to wake up and finally join the 2010s. "I'll make them as many Intel 16 [nanometer] chips as they want," Intel chief executive Pat Gelsinger told Fortune last week during his visit to an auto industry trade show in Germany. Carmakers have bombarded him with requests to invest in brand-new production capacity for semiconductors featuring designs that, at best, were state of the art when the first Apple iPhone launched. "It just makes no economic or strategic sense," said Gelsinger, who came to the auto show to convince carmakers they need to let go of the distant past. "Rather than spending billions on new 'old' fabs, let's spend millions to help migrate designs to modern ones...." Reliability plays a major concern. Most systems in cars are safety-critical and need to perform in practically every situation regardless of temperature, humidity, vibrations, and even minor road debris. With so much at stake, tried and true is better than new and improved.... If semiconductor suppliers like Intel and Qualcomm have their way, however, the days of the auto industry relying on these cheap commodity chips are numbered. The article cites a prediction that 10% of pre-pandemic car production could be eliminated due to chip shortages — and includes this quote from a press briefing by the Volkswagen Group's head of procurement. "Because of a 50-cent chip, we are unable to build a car that sells for $50,000."

    Samsung Engineers Propose 'Copying and Pasting' the Brain onto AI Chips
    Samsung has proposed a way to build brain-like computer chips by "copying and pasting" a brain's neuron wiring map onto 3D neuromorphic chips. Engadget reports: The approach would rely on a nanoelectrode array that enters a large volumes of neurons to record both where the neurons connect and the strength of those connections. You could copy that data and 'paste' it to a 3D network of solid-state memory, whether it's off-the-shelf flash storage or cutting-edge memory like resistive RAM. Each memory unit would have a conductance that reflects the strength of each neuron connection in the map. The result would be an effective return to "reverse engineering the brain" like scientists originally wanted, Samsung said. The move could serve as a 'shortcut' to artificial intelligence systems that behave like real brains, including the flexibility to learn new concepts and adapt to changing conditions. You might even see fully autonomous machines with true cognition, according to the researchers. "Envisioned by the leading engineers and scholars from Samsung and Harvard University, the insight was published as a Perspective paper, titled 'Neuromorphic electronics based on copying and pasting the brain'..." Samsung said in a statement. In short, they're proposing a method that "directly downloads the brain's neuronal connection map onto the memory chip."

    US Military Seeks Comments on Its Plan to Build a Small, Transportable Nuclear Reactor
    America's Department of Defense "is taking input on its plan to build an advanced mobile nuclear microreactor prototype at the Idaho National Laboratory in eastern Idaho," reports the Associated Press: The department began a 45-day comment period on Friday with the release of a draft environmental impact study evaluating alternatives for building and operating the microreactor that could produce 1 to 5 megawatts of power. The department's energy needs are expected to increase, it said. "A safe, small, transportable nuclear reactor would address this growing demand with a resilient, carbon-free energy source that would not add to the DoD's fuel needs, while supporting mission-critical operations in remote and austere environments," the Defense Department said. The draft environmental impact statement cites President Joe Biden's January 27 executive order prioritizing climate change considerations in national security as another reason for pursuing microreactors. The draft document said alternative energy sources such as wind and solar were problematic because they are limited by location, weather and available land area, and would require redundant power supplies. The department said it uses 30 terawatt-hours of electricity per year and more than 10 million gallons (37.9 million liters) of fuel per day. Powering bases using diesel generators strains operations and planning, the department said, and need is expected to grow during a transition to an electrical, non-tactical vehicle fleet. Thirty terawatt-hours is more energy than many small countries use in a year. The department in the 314-page draft environmental impact statement said it wants to reduce reliance on local electric grids, which are highly vulnerable to prolonged outages from natural disasters, cyberattacks, domestic terrorism and failure from lack of maintenance. The department also said new technologies such as drones and radar systems increase energy demands... The Defense Department said a final environmental impact statement and decision about how or whether to move forward is expected in early 2022. If approved, preparing testing sites at the Idaho National Lab and then building and testing of the microreactor would take about three years.
