Forget lithium ion — world’s first silicon-carbon battery blows that tech away

Forget lithium ion — world’s first silicon-carbon battery blows that tech away Story by Richard Priday • February 28, 2023 Phone maker Honor showed off a world-first battery that's made using silicon and carbon to give upcoming handsets a distinct capacity advantage over those using currently available battery tech. During the on-stage announcement at MWC 2023, Honor CEO George Zhao claimed the battery features a 12.8% higher energy density compared to regular graphite batteries. That means either the same capacity as a typical battery in a smaller space, or more capacity in the same space, depending on how you wish to take advantage of the new technology. Zhao put this announcement in context by saying that if the newly released Honor Magic5 Pro used this technology, its 5,100 mAh battery would instead have a capacity of 5,450 mAh. Honor drew attention to the "low voltage aggregation technology" that makes this capacity increase possible. Capacity at 3.5V is 240% better on the silicon-carbon battery than on a normal battery, which Zhao claimed would help in those awkward moments when your smartphone is on low charge and starts draining the battery faster to continue drawing the same current. Zhao concluded by saying he believed this technology would come "very soon," which hopefully means it'll only take a generation or two of Honor smartphones before we get to try out this new battery tech. In fact, the future may have already arrived in China, as the version of the Magic5 Pro shipping there is listed with the 5,450 mAh battery capacity that Zhao mentioned. We have to admit we're a bit jealous that version is not being offered on the global model. Our best phone battery life champions can all last at least 11 hours on our custom battery test, and while we haven't tested the Magic5 Pro yet, its larger-than-average battery should mean positive things for its longevity. No doubt whenever a phone with a silicon-carbon battery turns up on European or American shores, it'll also stand a strong chance of making it onto that list. https://www.msn.com/en-us/news/technology/forget-lithium-ion-world-s-first-silicon-carbon-battery-blows-that-tech-away/ar-AA1834RE?ocid=msedgntp&cvid=56e1678729e14f6aa227e9f121ad08ad&ei=9

Report: World’s 1st remote brain surgery via 5G network performed in China

World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 ·           A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media  reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling.  “You barely feel that the patient is 3,000 kilometers away,”  he said.

Visualizing The Power Of The World's Supercomputers

Visualizing The Power Of The World's Supercomputers   BY TYLER DURDEN FRIDAY, JAN 21, 2022 - 04:15 AM   A supercomputer is a machine that is built to handle billions, if not trillions of calculations at once. Each supercomputer is actually made up of many individual computers (known as nodes) that work together in parallel. A common metric for measuring the performance of these machines is  flops , or  floating point operations per second . In this visualization,  Visual Capitalist's Marcus Lu uses  November 2021 data from  TOP500  to visualize the computing power of the world’s top five supercomputers. For added context, a number of modern consumer devices were included in the comparison. Ranking by Teraflops Because supercomputers can achieve over one quadrillion flops, and consumer devices are much less powerful, we’ve used  teraflops  as our comparison metric. 1 teraflop = 1,000,000,000,000 (1 trillion) flops. Supercomputer Fugaku  was completed in March 202

BMW traps alleged thief by remotely locking him in car

BMW traps alleged thief by remotely locking him in car Stealer's Wheel? Seattle police department quotes "Watchmen" movie in a recap of the recent arrest. Tech Culture by Gael Fashingbauer Cooper December 4, 2016 5:00 PM PST It's maybe the most satisfying arrest we can imagine. Seattle police caught an alleged car thief by enlisting the help of car maker BMW to both track and then remotely lock the luckless criminal in the very car he was trying to steal. Jonah Spangenthal-Lee, deputy director of communications for the Seattle Police Department, posted a witty summary of the event on the SPD's blog on Wednesday. Turns out if you're inside a stolen car, it's perhaps not the best time to take a nap. "A car thief awoke from a sound slumber Sunday morning (Nov. 27) to find he had been remotely locked inside a stolen BMW, just as Seattle police officers were bearing down on him," Spangenthal-Lee wrote. The suspect found a ke
