"Saudi Arabia has cut oil and gas production following drone attacks on two major oil facilities run by state-owned company Aramco..." reports the BBC. "TV footage showed a huge blaze at Abqaiq, site of Aramco's largest oil processing plant [the world's biggest oil producer], while a second drone attack started fires in the Khurais oilfield."

The Iran-aligned Houthi movement (fighting the Western-backed military coalition supporting Yemen's government) has claimed credit for the attacks. Slashdot reader dryriver shared this report from the BBC: Energy Minister Prince Abdulaziz bin Salman said the strikes had reduced crude oil production by 5.7m barrels a day -- about half the kingdom's output. A Yemeni Houthi rebel spokesman said it had deployed 10 drones in the attacks...

In a statement carried by the Saudi Press Agency (SPA), Prince Abdulaziz said the attacks "resulted in a temporary suspension of production at Abqaiq and Khurais plants". He said that part of the reduction would be compensated for by drawing on Aramco's oil stocks. The situation was under control at both facilities, Aramco CEO Amin Nasser said, adding that no casualties had been reported in the attacks.
The BBC also notes that Saudi Arabia produces 10% of the world's crude oil, adding that "cutting this in half could have a significant effect on the oil price come Monday when markets open."

Hot power cables snake through tunnels and channel under cities all around the world. All it takes is a fan/air coil to capture that heat for buildings. Researchers and a power company in the UK calculate that the essentially free heat could warm thousands of London homes. An anonymous Slashdot reader shares a report from IEEE Spectrum: Underneath London's bustling streets lie several kilometers of 2.5-meter-wide concrete tunnels lined with power distribution cables that can reach blistering temperatures. To cool the tunnels, vertical shafts spaced out every kilometer or two supply fresh air and eject hot air out into the open. Researchers at London South Bank University (LSBU) want to put that waste heat to use. A typical 1.8-km tunnel stretch between ventilation shafts produces 400 kilowatts of heat, enough to heat 100 homes or a small commercial office, they have found in a preliminary analysis done with the city's electricity network operator UK Power Networks.

This heat recovery scheme would have a third of the carbon emissions of a gas boiler delivering the same amount of heat. The researchers presented this work at the International Congress of Refrigeration in August. [...] A heat exchanger installed at the supply shaft reduced cable and tunnel air temperatures by 8 degrees Celsius, but the amount of heat recovered varied from about 100 kilowatts in colder months to 460 kW in high heat. Installed at the exhaust shaft, the system produced around 400 kW during all six months.

mrwireless writes: YouTube channel Real Engineering has posted a great video on the potential (and downsides) of geothermal power. I think it would be great to discuss this video on Slashdot, since in discussions about climate change, geothermal rarely comes up as a viable alternative.

The video mentions things like:
- Could power our needs twice over
- New technology makes it possible in more locations
- Works night and day
- Could be cost competitive (according to an MIT study)
- Workers from the oil drilling industry could find new jobs in this sector

So: why isn't geo-thermal energy getting as much attention as solar and wind?

According to leaker and former Apple blogger Sonny Dickson, the iPhone 11 lineup includes the necessary hardware for a two-way charging feature that was widely rumored for the devices, but Apple has disabled the feature on the software end. MacRumors reports: For months ahead of their unveiling, the latest iPhones were rumored to feature a Qi-based device-to-device charging feature, allowing for an Apple Watch, AirPods, and other accessories to charge on the back of the iPhones. The feature was expected to be similar to Wireless PowerShare on Samsung's Galaxy S10. The centered Apple logo on the iPhone 11 models was even believed to be partly intended to help customers know where to place their AirPods, Apple Watch, or other accessories to charge on the back of the iPhone.

Just hours before Apple's event this week, however, noted analyst Ming-Chi Kuo and Bloomberg's Mark Gurman said the feature appeared to have been canceled. In a note seen by MacRumors, Kuo said the feature was possibly abandoned because "the charging efficiency may not meet Apple's requirements." Teardowns of the iPhone 11 models will soon confirm whether the two-way charging hardware is in fact present in the devices. Deliveries to customers and in-store availability will begin Friday, September 20.

In new research published on Thursday in the journal Joule, Dr. Raman, an electrical engineer at the University of California, Los Angeles, demonstrated a way to harness a dark night sky to power a light bulb. The New York Times reports: His prototype device employs radiative cooling, the phenomenon that makes buildings and parks feel cooler than the surrounding air after sunset. As Dr. Raman's device releases heat, it does so unevenly, the top side cooling more than the bottom. It then converts the difference in heat into electricity. In the paper, Dr. Raman described how the device, when connected to a voltage converter, was able to power a white LED. The prototype built by Dr. Raman resembles a hockey puck set inside a chafing dish. The puck is a polystyrene disk coated in black paint and covered with a wind shield. At its heart is an off-the shelf gadget called a thermoelectric generator, which uses the difference in temperature between opposite sides of the device to generate a current. A similar device powers NASA's Curiosity rover on Mars; its thermoelectric generator derives heat from plutonium radiation. Usually, the temperature difference in these generators is stark, and they are carefully engineered to separate hot and cold. Dr. Raman's device instead uses the atmosphere's ambient temperature as the heat source. The shift from warm to cool is very slight, meaning the device can't produce much power.

His puck-in-a-dish is elevated on aluminum legs, enabling air to flow around it. As the dark puck loses warmth to the night sky, the side facing the stars grows colder than the side facing the air-warmed tabletop. This slight difference in temperature generates a flow of electricity. When paired with a voltage converter, the prototype produced 25 milliwatts of power per square meter. That is about three orders of magnitude lower than what a typical solar panel produces, and well short of even the roughly 4-watt maximum efficiency for such devices. Still, several experts said the prototype was an important contribution to a new and relatively unusual space in the renewable energy sector.

MojoKid writes: Gamer-targeted smartphones are beginning to pop up more often now, with devices like the Razer Phone 2, Xiaomi Black Shark, and the ASUS ROG Phone making waves in the market with performance enthusiasts. The latest release from ASUS, the ROG Phone II sports a specially binned chip from Qualcomm called the Snapdragon 855+. The higher performance SoC sports an octa-core CPU clocked at 2.96GHz, paired with an overclocked Adreno 640 GPU that can boost its performance up to 15 percent above spec. A generous 12GB of RAM, 1TB of storage and a 120Hz 6.59 FHD display trim out the rest of the ASUS ROG Phone II's specs. In addition, an enhanced on-board cooling system features a 3D vapor chamber, heat spreaders, and cooling pads that efficiently dissipate heat from inside the phone to the outside. It is designed to be above spec for the Snapdragon 855 chipset and necessary to keep 855+ stable during long gaming sessions. In benchmark testing, there's no question these system upgrades put up significantly better numbers than the average high-end Android phone on the market these days, such that the phone is about 10% faster than devices like Samsung's Galaxy Note 10 or the OnePlus 7 Pro. The ASUS ROG Phone II will be available later this month but pricing is still being determined.

Irreparably damaged your phone in a freak accident? Not to worry -- Google's got your back. From a report: The search giant today announced that subscribers to Google One, a subscription service that offers expanded cloud storage, can now take advantage of a whole-phone backup solution for Android that automatically copies videos, multimedia messages (MMS), and uncompressed photos to Google's datacenters. But wait, you might say, doesn't Google already offer a free backup solution for Android? That's true, but it only covers content, select data (apps, call history, contacts, and calendar), and settings. (Only Pixel phones get native SMS backup.) And while Google's eponymous Google Photos service backs up photos and videos for free, it by default resizes pics to 16MP (original-quality photos count against your Google Account storage). Google One doesn't touch photos before uploading them, and it throws in the aforementioned text messages backup at no extra charge.

An anonymous reader quotes a report from the BBC: McDonald's is to replace human servers with voice-based technology in its U.S. drive-throughs. The fast-food chain hopes the AI technology will make the ordering process more efficient. McDonald's is implementing the technology with the help of start-up Apprente, which it acquired this week. The move comes amid concern about workers whose jobs may become obsolete as a result of automation and new technologies. McDonald's plans to expand its newly formed McD Tech team by hiring more engineers and data scientists. The report notes that the company recently "invested in technology that could automatically alter individual drive-through menu panels, depending on factors such as the weather, for example automatically suggesting McFlurry ice cream on hot days or telling customers which items were already proving popular at that particular restaurant that day."

omfglearntoplay shares a report from CNN: Eight years after Japan's worst nuclear disaster, the government is not sure what to do with the contaminated water that remains -- but its environment minister says dumping it into the ocean might be the only choice. To cool fuel cores at the damaged Fukushima nuclear plant, operator Tokyo Electric has pumped in tens of thousands of tons of water over the years, according to Japanese national broadcaster NHK. Once used and contaminated, the water is put into storage. Now, storage space is running out. And during a televised press conference Tuesday, Japan's environment minister Yoshiaki Harada said he believed the only solution was to "release it into the ocean and dilute it." "There are no other options," he said. Japan's Chief Cabinet Secretary Yoshihide Suga emphasized that a decision has not yet been made. "There is no fact that the method of disposal of contaminated water has been decided," he said. "The government would like to make a decision after making thorough discussion."

Qbertino writes: The VW ID.3 (VW German Minisite and Configurator) is a compact car with a design loosely based on the very successful VW Golf line. The base model costs less than $33,000 with ranges of 330, 420, and 550 kilometers (or 205, 261 and 340 miles). Along with the car comes a new corporate identity with a newly designed logo reminiscent of the dawn of VW, signaling VW's transition into the electric era it announced with fanfare a while back. VW also isn't too shabby about giving credit where credit is due. "Without Elon Musk my job would be considerably harder," VW Chief Strategist Michael Jost was quoted as saying a few days ago. The base model of the ID.3 will only charge up to 50kW, but owners who want to charge faster (up to 100kW) can pay extra for that ability. "100kW charging will come standard on the midrange 58kWh version, while even faster 125kW charging will be available on the top-tier ID.3," reports The Verge. "The company is also offering an eight year / 160,000 kilometer warranty on the ID.3's battery pack."

According to a new study from the Rocky Mountain Institute, natural gas-fired power plants are on the path to being undercut themselves by renewable power and big batteries. Bloomberg reports: By 2035, it will be more expensive to run 90% of gas plants being proposed in the U.S. than it will be to build new wind and solar farms equipped with storage systems, according to the report. It will happen so quickly that gas plants now on the drawing boards will become uneconomical before their owners finish paying for them, the study said. The development would be a dramatic reversal of fortune for gas plants, which 20 years ago supplied less than 20% of electricity in the U.S. Today that share has jumped to 35% as hydraulic fracturing has made natural gas cheap and plentiful, forcing scores of coal plants to close nationwide.

The authors of the study say they analyzed the costs of construction, fuel and anticipated operations for 68 gigawatts of gas plants proposed across the U.S. They compared those costs to building a combination of solar farms, wind plants and battery systems that, together with conservation efforts, could supply the same amount of electricity and keep the grid stable. As gas plants lose their edge in power markets, the economics of pipelines will suffer, too, RMI said in a separate study Monday. Even lines now in the planning stages could soon be out of the money, the report found.

In an opinion article published last week on Wired, New York City Mayor and 2020 Democratic presidential candidate Bill de Blasio said as president he would issue a robot tax for corporations displacing humans and would create a federal agency to oversee automation. CNET reports: "The scale of automation in our economy is increasing far faster than most people realize, and its impact on working people in America and across the world, unless corralled, will be devastating," de Blasio wrote. De Blasio would call the new regulator the Federal Automation and Worker Protection Agency, which would safeguard jobs and communities. In addition, his proposed "robot tax" would be imposed on large companies that eliminate jobs as they become more automated. The tax would be equal to five years of payroll taxes for each employee eliminated, according to De Blasio.

"Biohackers took one small but important step toward the science fiction dystopia depicted in William Gibson's Johnny Mnemonic," reports The Parallax, in an article shared by a Slashdot reader: The Four Thieves Vinegar biohacking collective has not figured out how to precisely mimic the memory data transfer scenario Gibson conjured, but it has built a device to enable people to store and transfer data wirelessly in their bodies. Using off-the-shelf parts and focused efforts, the biohacking group has designed and built a networked hard drive, coated in a biosafe resin, to be subcutaneously implanted in the human body. It's powered by an external battery that connects to the device via an induction coil, and its storage capacity is limited only by the size of the microSD card it contains. Michael Laufer, who founded Four Thieves Vinegar, calls it the Pegleg.

In the small hours of August 8, in an operating room within the small house, two patients received the second version of the Pegleg implant, which Laufer says is the world's first subcutaneous networked drive... To make Pegleg v2, Laufer and his team removed from the Raspberry Pi both Micro USB connectors (one for power, one for data), the Mini HDMI connector, and the camera connector. They then soldered on a second Wi-Fi chip to enable it to transfer data to another Pegleg and allow other devices to connect to it, as well as an induction coil to enable it to be powered by a wireless battery resting in a contiguous sports armband or pants pocket. They enabled Bluetooth for future functionality, inserted a 512GB microSD card for storage, and updated the firmware. Finally, they coated the hacked device in a biocompatible acrylic resin to prevent it from interacting with the recipient's body and to diffuse the heat it emanates.

At 11:44 a.m. on the same day, Laufer -- an implant newbie who has three small tattoos but no piercings -- took a seat in the surgical room... During the procedure, Laufer passed out for a few seconds and vomited a little bit. But 32 minutes later, he had a functional "Pegleg" implant.

The electric utility non-profit NERC has posted a "Lessons Learned" document detailing a March 5th incident that Environment & Energy News calls "a first-of-its-kind cyberattack on the U.S. grid". While it didn't cause any blackouts -- it was at a "low-impact" control center -- NERC is now warning power utilities to "have as few internet facing devices as possible" and to use more than just a firewall for defense.

puddingebola shared this report from Environment & Energy News: The cyberthreat appears to have been simpler and far less dangerous than the hacks in Ukraine. The March 5 attack hit web portals for firewalls in use at the undisclosed utility. The hacker or hackers may not have even realized that the online interface was linked to parts of the power grid in California, Utah and Wyoming. "So far, I don't see any evidence that this was really targeted," said Reid Wightman, senior vulnerability analyst at industrial cybersecurity firm Dragos Inc. "This was probably just an automated bot that was scanning the internet for vulnerable devices, or some script kiddie," he said, using a term for an unskilled hacker...

In the March episode, a flaw in the victim utility's firewalls allowed "an unauthenticated attacker" to reboot them over and over again, effectively breaking them. The firewalls served as traffic cops for data flowing between generation sites and the utility's control center, so operators lost contact with those parts of the grid each time the devices winked off and on. The glitches persisted for about 10 hours, according to NERC, and the fact that there were issues at multiple sites "raised suspicion." After an initial investigation, the utility decided to ask its firewall manufacturer to review what happened, according to NERC, which led to the discovery of "an external entity" -- a hacker or hackers -- interfering with the devices. NERC stressed that "there was no impact to generation...."

Wightman said the "biggest problem" was the fact that hackers were able to successfully take advantage of a known flaw in the firewall's interface. "The advisory even goes on to say that there were public exploits available for the particular bug involved," he said. "Why didn't somebody say, 'Hey, we have these firewalls and they're exposed to the internet -- we should be patching?'"

Large power utilities are required to check for and apply fixes to sensitive grid software that could offer an entry point for hackers.
