An anonymous reader shares the findings of a new study from the University of Chicago. From a report: If service becomes slow when you're trying to send a quick email on your smartphone, you might scroll through your network options and discover how many Wi-Fi networks there are. In fact, this plethora of options is itself the problem. These networks are in competition with one another, limiting the speed at which each can operate. University of Chicago researchers have demonstrated how this increased network competition could negatively impact internet service for everyday users.

When a cellular provider, such as T-Mobile or AT&T, licenses a spectrum band from the FCC, they reserve its exclusive use. As a result, networks operating on licensed bands experience little interference. This allows providers to establish fast and reliable service, but it comes at a cost. To improve bandwidth [to accommodate] more users] without breaking the bank, these providers have begun to also use the unlicensed spectrum via cellular networks using a mode called licensed assisted access (LAA), which operates on the same bands used for Wi-Fi. [The researchers] set out to examine how this shared use of the unlicensed spectrum, called coexistence, impacted both Wi-Fi and cellular users.

"We actually found an LAA station located on the UChicago campus, on a pole in front of the bookstore, and in this outside space campus Wi-Fi is also in use," [Monisha Ghosh, associate member in the Department of Computer Science at the University of Chicago and research professor in the Pritzker School of Molecular Engineering] said. "That provided an experimental platform in our backyard, so we started taking measurements." [...] By accessing multiple networks simultaneously, the group found that competition decreased performance -- reducing the amount of data transmitted, the speed of transmission, and the signal quality. This competition was particularly detrimental to Wi-Fi. When LAA was also in active use, data transmitted by Wi-Fi users decreased up to 97%. Conversely, LAA data only exhibited a 35% decrease when Wi-FI was also in use. Ghosh explained that the incompatibility between Wi-Fi and LAA owes in part to the different protocols each employs to deal with heavy internet traffic. The researchers presented their findings in a paper via arXiv.

A wireless pacemaker that can dissolve in the body has been created for patients who need only temporary help to regulate their heartbeat. The Guardian reports: While pacemakers can already be used for temporary periods, experts say there are problems, including that leads placed through the skin can pose an infection risk. The external power supply and control system can become accidentally dislodged, and heart tissue can be damaged when the device is removed. Now researchers say they have developed a battery-free pacemaker that can be implanted directly on to the surface of the heart and absorbed by the body when no longer needed. The device -- which Rogers said would cost about $100 -- is free of leads and can be controlled and programmed from outside the body.

Writing in the journal Nature Biotechnology, Rogers and colleagues report how they made the device -- which is thin, flexible and weighs less than half a gram -- from materials including magnesium, tungsten, silicon and a polymer known as PLGA, all of which are compatible with the body but which undergo chemical reactions that allow them to dissolve and be absorbed over time. The device, which resembles a tiny tennis racket in shape, is powered by wireless technology in which radio frequency power from an external device is sent to a receiver within the pacemaker where it is converted into an electrical current that is used to regulate the heart. Rogers said similar technology was used in applications such as wireless charging of smartphones and electric toothbrushes.

An anonymous reader quotes a report from 9to5Google: SMS is widely regarded as an insecure form of two-factor authentication, and another example of this has just emerged. A carrier looks to be injecting ads into the Google verification code used to sign in to services like Gmail. Action Launcher developer Chris Lacy today tweeted how his Google verification code -- which starts with "G-" -- featured an "SMS AD." The advertisement -- for a VPN -- includes a quick message and short URL. For those that immediately suspect this is just a phishing attempt, the verification code is legitimate and was requested by Lacy to successfully verify a login attempt. Google Messages even flagged the link/message as spam. As such, Googlers responding to the thread suspect this is an occurrence of a carrier appending an ad -- note the extra spaces -- into a real text message. It's very unlikely that Google's security teams would allow advertising into a very crucial part of the login process where end user trust is paramount.

Google issued the following statement to us today: "These are not our ads and we are currently working with the wireless carrier to understand why this happened." Google confirms that the "SMS AD" did not originate from its own advertising network. Meanwhile, it's working with the wireless carrier in question to find out what occurred. Lacy has decided "not to state the carrier for privacy reasons," and Google did not share that information either.

An anonymous reader quotes a report from The Verge: United Airlines is adding a long-awaited feature to the in-flight entertainment seatback screens of its new Boeing 737 Max 8 jets -- support for Bluetooth headphones. The company is making the upgrade as part of "United Next," a new plan to expand and modernize its fleet with what it says are larger, fuel-efficient jets and a more comfortable in-flight experience. Adding seatback screens made a huge difference in how tolerable flying is, but it's been held up by lagging audio support that The Verge has even written a guide to getting around. And this isn't a problem unique to United. Other airlines like Delta or JetBlue have been offering seatback screens for years, but have also saddled flyers with analog audio. United just might be one of the first airlines to start the next wave of inflight entertainment improvements (hopefully).

However, there's room for things to go a bit sideways. As part of its upgrades, United's new 737 Max 8 jets offer 10 or 13-inch inflight entertainment screens on the backs of all seats, which might mean a lot of people trying to connect to Bluetooth at once. That could cause interference, and might also make the process of connecting your headphones more of a chore if you're having to hunt through multiple devices trying to pair in the same menu. United currently only offers Bluetooth on its Max 8 jets which it says should start flying this summer. The company didn't share how it plans to address issues with Bluetooth, but said it's still "studying the technology."

London Underground passengers will be able to get mobile coverage across the rail network by the end of 2024, it has been announced. MacRumors reports: In a press release, Transport for London (TfL) said the capital's Oxford Circus, Tottenham Court Road and Bank stations would be among the first fully connected stations by the end of the year, followed by Tottenham Court Road, Euston, and Camden Town by the end of 2022. Mobile reception was introduced on the eastern half of the Jubilee line in March last year. TfL says the additional infrastructure will support 5G as well as 4G, but that it will be the responsibility of mobile operators to offer support for the fastest network speeds.

TfL is partnering with BAI Communications (BAI), a global provider of 4G and 5G connected infrastructure, to plug so-called coverage "not-spots" in the underground network. The over 1,242 miles of fibre cabling installed in London Underground tunnels will also benefit above-ground coverage for buildings and other infrastructure by allowing more mobile transmitters to be installed.

The BBC reports: China's Zhurong rover has sent back a batch of new images from Mars — including a "selfie". The robot, which landed in May, positioned a wireless camera on the ground and then rolled back a short distance to take the snap. To Zhurong's right is the rocket-powered platform that brought the six-wheeled vehicle to a soft touchdown. Both display prominent Chinese flags...

It weighs some 240kg. A tall mast carries cameras to take pictures and aid navigation; five additional instruments will investigate the mineralogy of local rocks and the general nature of the environment, including the weather. Like the current American rovers (Curiosity and Perseverance), Zhurong has a laser tool to zap rocks to assess their chemistry. It also has a radar to look for sub-surface water-ice - a capability it shares with Perseverance.
Slashdot reader InfiniteZero writes that the mission's "full resolution images including a 360 panoramic view of the landing site, can be found at the official CNSA website."

The three major carriers in the U.S. have now agreed to start providing vertical location data for 911 calls, which will help first responders quickly locate 911 callers in multi-story buildings. XDA Developers reports: The FCC wrote in its announcement, "FCC Acting Chairwoman Jessica Rosenworcel today announced breakthrough agreements with America's three largest mobile phone providers to start delivering vertical location information in connection with 911 calls nationwide in the coming days. This information will help first responders quickly locate 911 callers in multi-story buildings, which will reduce response times and ultimately save lives."

The FCC first announced in 2015 that carriers would be required to start sharing vertical location data. The original deadline was June 2nd, 2021, but AT&T, T-Mobile, and Verizon wanted an 18-month extension (allegedly due to issues testing the functionality during the COVID-19 pandemic). With the deadline rapidly approaching, the FCC began an investigation in April to find out what was taking carriers so long. All three major carriers have now agreed to start providing vertical location data to 911 call centers within the next seven days, and each company will pay a $100,000 settlement. The agreement also increases the scope of the vertical location data; instead of the data only being provided in select areas, vertical location information will be provided by carriers across the entire United States. However, it will likely take longer than a week for the vertical data to be used in most 9-1-1 call centers, as the change will require updated software and (possibly) additional training for emergency dispatchers.

An anonymous reader quotes a report from Bloomberg: Apple is working on a new iPad Pro with wireless charging and the first iPad mini redesign in six years, seeking to continue momentum for a category that saw rejuvenated sales during the pandemic. The Cupertino, California-based company is planning to release the new iPad Pro in 2022 and the iPad mini later this year [...]. The main design change in testing for the iPad Pro is a switch to a glass back from the current aluminum enclosure. The updated iPad mini is planned to have narrower screen borders while the removal of its home button has also been tested.

For the new Pro model, the switch to a glass back is being tested, in part, to enable wireless charging for the first time. Making the change in material would bring iPads closer to iPhones, which Apple has transitioned from aluminum to glass backs in recent years. Apple's development work on the new iPad Pro is still early, and the company's plans could change or be canceled before next year's launch [...]. Wireless charging replaces the usual power cable with an inductive mat, which makes it easier for users to top up their device's battery. It has grown into a common feature in smartphones but is a rarity among tablets. Apple added wireless charging to iPhones in 2017 and last year updated it with a magnet-based MagSafe system that ensured more consistent charging speeds.

The company is testing a similar MagSafe system for the iPad Pro. Wireless charging will likely be slower than directly plugging in a charger to the iPad's Thunderbolt port, which will remain as part of the next models. As part of its development of the next iPad Pro, Apple is also trying out technology called reverse wireless charging. That would allow users to charge their iPhone or other gadgets by laying them on the back of the tablet. Apple had previously been working on making this possible for the iPhone to charge AirPods and Apple Watches. In addition to the next-generation iPad Pro and iPad mini, Apple is also working on a thinner version of its entry-level iPad geared toward students. That product is planned to be released as early as the end of this year, about the same time as the new iPad mini. Apple is still reportedly working on a technology similar to its failed AirPower, a charging mat designed to simultaneously charge an iPhone, Apple Watch and AirPods. People familiar with the matter said it's also internally investigating alternative wireless charging methods that can work over greater distances than an inductive connection.

After being announced in 2017, the Atari VCS game console finally has a launch date: June 15th. HotHardware reports: However, pricing for the Atari VCS might leave many scratching their heads, especially considering that it is retro-centric and uses seriously underpowered hardware compared to modern gaming consoles from Sony and Microsoft. The base Onyx system is priced at $299, while an Onyx or Black Walnut All-in Bundle includes a wireless Classic Joystick and a wireless Modern Controller. Unfortunately, that bundle will set you back an eye-popping $399.

The Atari VCS [...] uses a rather pokey AMD Ryzen R1606G embedded APU. [...] However, Atari says that the VCS can also function as a full-fledged PC. You can even install Windows 10 or Linux on it, turning it into a versatile multimedia computer. The hardware is reportedly capable of running 4K videos and includes a built-in "Vault" containing 100 retro Atari 2600 and arcade games. That's all well and good for those with a penchant for retro gaming, but remember that we're talking about games that debuted roughly 40 years ago. That nostalgia could run a bit thin when you're talking about a device that costs $299 and up. Atari says over 11,000 of its original Indiegogo campaign backers have already received their consoles. Everyone else will have to purchase directly from Atari or a third party.

Samsung is killing the first-generation SmartThings Hub at the end of the month, kicking off phase two of its plan to shut down the SmartThings ecosystem and force users over to in-house Samsung infrastructure. "Phase one was in October, when Samsung killed the Classic SmartThings app and replaced it with a byzantine disaster of an app that it developed in house," writes Ars Technica's Ron Amadeo. "Phase three will see the shutdown of the SmartThings Groovy IDE, an excellent feature that lets members of the community develop SmartThings device handlers and complicated automation apps." From the report: The SmartThings Hub is basically a Wi-Fi access point -- but for your smart home stuff instead of your phones and laptops. Instead of Wi-Fi, SmartThings is the access point for a Zigbee and Z-Wave network, two ultra low-power mesh networks used by smart home devices. [...] The Hub connects your smart home network to the Internet, giving you access to a control app and connecting to other services like your favorite voice assistant. You might think that killing the old Hub could be a ploy to sell more hardware, but Samsung -- a hardware company -- is actually no longer interested in making SmartThings hardware. The company passed manufacturing for the latest "SmartThings Hub (v3)" to German Internet-of-things company Aeotec. The new Hub is normally $125, but Samsung is offering existing users a dirt-cheat $35 upgrade price.

For users who have to buy a new hub, migrating between hubs in the SmartThings ecosystem is a nightmare. Samsung doesn't provide any kind of migration program, so you have to unpair every single individual smart device from your old hub to pair it to the new one. This means you'll need to perform some kind of task on every light switch, bulb, outlet, and sensor, and you'll have to do the same for any other smart thing you've bought over the years. Doing this on each device is a hassle that usually involves finding the manual to look up the secret "exclusion" input, which is often some arcane Konami code. Picture holding the top button on a paddle light for seven seconds until a status light starts blinking and then opening up the SmartThings app to unpair it. Samsung is also killing the "SmartThings Link for Nvidia Shield" dongle, which let users turn Android TV devices into SmartThings Hubs.

Xiaomi's at it again: The company's new fast charging technology can get a smartphone from 0 to 100 percent battery in less than 8 minutes. From a report: The 200W wired charging tech, used on a modified Xiaomi MI 11 Pro with a 4,000mAh battery, gets the phone from 0-10% in just 44 seconds. The phone gets to 50% in 3 minutes, and it's fully charged in 7:57 minutes. In a YouTube video, Xiaomi also showcased its 120W wireless charging tech, which gets a smartphone with a 4,000mAh battery from 0 to 100 percent battery in 15 minutes.

If you use Alexa, Echo, or any other Amazon device, you have just over a week to opt out of an experiment that leaves your personal privacy and security hanging in the balance. From a report: On June 8, the merchant, Web host, and entertainment behemoth will automatically enroll the devices in Amazon Sidewalk. The new wireless mesh service will share a small slice of your Internet bandwidth with nearby neighbors who don't have connectivity and help you to their bandwidth when you don't have a connection.

By default, Amazon devices including Alexa, Echo, Ring, security cams, outdoor lights, motion sensors, and Tile trackers will enroll in the system. And since only a tiny fraction of people take the time to change default settings, that means millions of people will be co-opted into the program whether they know anything about it or not. The Amazon webpage linked above says Sidewalk "is currently only available in the US." [...] Amazon has published a white paper detailing the technical underpinnings and service terms that it says will protect the privacy and security of this bold undertaking. To be fair, the paper is fairly comprehensive, and so far no one has pointed out specific flaws that undermine the encryption or other safeguards being put in place. But there are enough theoretical risks to give users pause.

"A U.S.-backed consortium beat out one financed by China in a closely watched telecommunications auction in Ethiopia — handing Washington a victory in its push to challenge Beijing's economic influence around the world," reports the Wall Street Journal: The East African country said Saturday it tapped a group of telecommunications companies led by the U.K.'s Vodafone Group PLC to build a nationwide, 5G-capable wireless network.

The group had won financial backing for the multibillion-dollar project from a newly created U.S. foreign-aid agency. The agency offers low-interest loans, but the financing comes with a condition: the money won't be used to buy telecom equipment from China's Huawei Technologies Co. and ZTE Corp. Washington considers both a spying threat, an accusation the companies deny...

The telecom license auction in Ethiopia took on wider geopolitical significance amid heightened competition between the U.S. and China over key technological pursuits, from the rollout of 5G to chip manufacturing. "The U.S. and China are fighting a proxy war in Ethiopia for influence," said Zemedeneh Negatu, chairman of Fairfax Africa Fund LLC, a U.S.-based investment firm that focuses on Africa. After all but shutting out Huawei in the U.S., Washington has become more assertive about challenging Beijing's economic footprint overseas. It is using new financial tools to win influence and ensure that strategic assets in foreign countries stay in friendly hands...

Backing the Vodafone bid was the International Development Finance Corp., or DFC. The U.S. government-funded agency was created in December 2019 with a goal of offering alternatives to cheap, Chinese financing for foreign infrastructure projects... U.S. law also prohibits its loan from being used to buy Huawei or ZTE equipment, though one person familiar with the matter said it is possible the Vodafone-led bid could still buy some Chinese gear because of the project's size and cost.

Slashdot reader esm88 shares the BBC's story about a couple who experienced "a knock on the door from the police" investigating child abuse images posted online. "The couple insisted they had nothing to do with it. But the next few months were 'utter hell' as they attempted to clear their names," before their case was finally dropped in March: In February, a conversation with a friend who worked in cyber-security alerted them to the possibility that their router, supplied by their broadband provider Vodafone, might hold clues to what had happened. They had not changed the default passwords for either the router itself or the admin webpage, leaving it susceptible to brute force attacks. "We think of ourselves as competent users but we are not IT experts," said Matthew. "No-one told us to change the password and the setting up of the router didn't require us to go on to the admin menu, so we didn't.

"It came with a password, so we plugged it in and didn't touch anything."

Ken Munro, a security consultant with Pen Test Partners, told the BBC that it can take "a matter of minutes" for criminals to piggyback on insecure wireless connections... "So what I guess has happened here, is that the hacker has cracked the wi-fi password and then made changes to the router configuration, so their illicit activities on the internet appear to be coming from the innocent party." In March, when the couple's devices were returned and the case closed, the police officer assigned to liaise with them seemed to corroborate that unauthorised use of their wi-fi was to blame. But it couldn't be proved... The problem is industry-wide, points out Mr Munro.

"Internet service providers have started to improve matters to make these attacks harder, by putting unique passwords on each router. However, it will take years for all of the offending routers to be replaced," he said.

Israeli company ElectReon Wireless is building a kilometer-long stretch of electric vehicle-charging highway between Milan and Brescia in Italy. It's the first trial of its kind involving a highway and will help determine if the technology is ready for widespread adoption. Innovation Origins reports: In a nutshell, Electreon is building the infrastructure by installing copper coils under the asphalt. Energy is transferred directly and wirelessly to the vehicle's batteries while driving by means of magnetic induction. The system includes a control unit located on the side of the lane of the electrified road. A receiver is installed in the chassis of each electric vehicle that is participating in the trial.

ElectReon is working with more than ten Italian partners to carry out the test. The most important of these is Brebemi, who operate the toll road. The goal of the pilot is to see how the technology will fare on toll roads. Brebemi is footing the bill for the pilot project while ElectReon will supply the wireless electric road system. "Dynamic Wireless Power Transfer," as the technology is called, will be tested on different types of electric vehicles in both stationary and dynamic environments.

An anonymous reader writes: NBN Co has been forced to replace 10,000 faulty broadband devices in homes across the Blue Mountains west of Sydney after residents reported the technology was frequently struck by lightning and in one instance led to blue sparks flying out of a modem in a family's home. About 20,000 of the more than 32,000 homes in the Blue Mountains and Emu Plains have been connected to the national broadband network via fibre-to-the-curb (FttC) technology, which was set up under the Coalition government's multi-technology mixed model. That means fibre runs all the way to the edge of the property and connects to the home via the existing copper wire lead-ins from the curb.

Electrical storms in the Blue Mountains have wreaked havoc on the boxes that link the fibre to the copper. When lightning strikes the distribution boxes outside the house, sparks are sent flying up the copper lines, in turn frying the modems in people's homes. Guardian Australia understands the company has replaced 10,000 -- or half -- of devices inside the home that the company has identified as being prone to be affected by lightning. A spokesman for NBN Co confirmed that the company had found issues with the devices in areas of hard ground like sandstone. Sandstone is more resistant to electrical conduction than other soft earths. He said the devices fail in a safe way but the company nevertheless is issuing replacement devices people can install themselves. "We are now deploying a strengthened [device] that is much less likely to fail in these conditions.

A tech columnist for Inc. noticed that on June 8th Amazon will finally power up its massive "Sidewalk" mesh network (which uses Bluetooth and 900MHz radio signals to communicate between devices). And millions and millions of Amazon customers are all already "opted in" by default: The idea behind it is actually really smart — make it possible for smart home devices to serve as a sort of bridge between your WiFi connection and one another. That way, if your Ring doorbell, for example, isn't located close to your WiFi router, but it happens to be near an Echo Dot, it can use Sidewalk to stay connected.

The same is true if your internet connection is down. Your smart devices can connect to other smart devices, even if they aren't in your home. The big news on this front is that Tile is joining the Sidewalk network on June 14. That means that if you lose a Tile tracker, it can connect to any of the millions of Echo or Ring devices in your neighborhood and send its location back to you.

That's definitely a nice benefit, but it's also where things get a little murky from a privacy standpoint. That's because other people's devices, like your neighbor's, can also connect to your network. Amazon is pretty clear that Sidewalk uses three layers of encryption so that no data is shared between say, someone's Tile tracker and your network. The signal from the Tile is encrypted all the way back to the Tile app on your iPhone or Android smartphone... [But] whether or not you want your device connecting to other devices, or want your neighbors connecting to your WiFi, Amazon went ahead and made Sidewalk opt-out.
Opt out (for all your devices) using Alexa app's More tab (at the bottom): Settings > Account Settings > Amazon Sidewalk > Enabled.

Implantable miniaturized medical devices that wirelessly transmit data "are transforming healthcare and improving the quality of life for millions of people," writes Columbia University, noting the devices are "widely used to monitor and map biological signals, to support and enhance physiological functions, and to treat diseases."

Long-time Slashdot reader sandbagger shares the university's newest announcement: These devices could be used to monitor physiological conditions, such as temperature, blood pressure, glucose, and respiration for both diagnostic and therapeutic procedures. To date, conventional implanted electronics have been highly volume-inefficient — they generally require multiple chips, packaging, wires, and external transducers, and batteries are often needed for energy storage... Researchers at Columbia Engineering report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm cubed. The system is as small as a dust mite and visible only under a microscope...

"We wanted to see how far we could push the limits on how small a functioning chip we could make," said the study's leader Ken Shepard, Lau Family professor of electrical engineering and professor of biomedical engineering. "This is a new idea of 'chip as system' — this is a chip that alone, with nothing else, is a complete functioning electronic system. This should be revolutionary for developing wireless, miniaturized implantable medical devices that can sense different things, be used in clinical applications, and eventually approved for human use...."

The chip, which is the entire implantable/injectable mote with no additional packaging, was fabricated at the Taiwan Semiconductor Manufacturing Company with additional process modifications performed in the Columbia Nano Initiative cleanroom and the City University of New York Advanced Science Research Center (ASRC) Nanofabrication Facility. Shepard commented, "This is a nice example of 'more than Moore' technology—we introduced new materials onto standard complementary metal-oxide-semiconductor to provide new function. In this case, we added piezoelectric materials directly onto the integrated circuit to transducer acoustic energy to electrical energy...." The team's goal is to develop chips that can be injected into the body with a hypodermic needle and then communicate back out of the body using ultrasound, providing information about something they measure locally.

The current devices measure body temperature, but there are many more possibilities the team is working on.

An anonymous reader quotes a report from ZDNet: Cloudflare is testing out the possibility of security keys replacing one of the most irritating aspects of web browsing: the CAPTCHA. CAPTCHAs are used to catch out bots that are trawling websites and are often implemented to prevent online services from being abused. "CAPTCHAs are effectively businesses putting friction in front of their users, and as anyone who has managed a high-performing online business will tell you, it's not something you want to do unless you have no choice," Cloudflare says.

To highlight the amount of time lost to these tests, Cloudflare said that based on calculations of an average of 32 seconds to complete a CAPTCHA, one test being performed every 10 days, and 4.6 billion internet users worldwide, roughly "500 human years [are] wasted every single day -- just for us to prove our humanity." On Thursday, Cloudflare research engineer Thibault Meunier said in a blog post that the company was "launching an experiment to end this madness" and get rid of CAPTCHAs completely. The means to do so? Using security keys as a way to prove we are human.

According to Meunier, Cloudflare is going to start with trusted security keys -- such as the YubiKey range, HyperFIDO keys, and Thetis FIDO U2F keys -- and use these physical authentication devices as a "cryptographic attestation of personhood." This is how it works: A user is challenged on a website, the user clicks a button along the lines of "I am human," and is then prompted to use a security device to prove themselves. A hardware security key is then plugged into their PC or tapped on a mobile device to provide a signature -- using wireless NFC in the latter example -- and a cryptographic attestation is then sent to the challenging website. Cloudflare says the test takes no more than three clicks and an average of five seconds -- potentially a vast improvement on the CAPTCHA's average of 32 seconds. You can access cloudflarechallenge.com to try out the system.

An anonymous reader quotes a report from Jalopnik: [R]esearchers at Cornell University, led by Associate Professor of Electrical and Computer Engineering Khurram Afridi, have developed technology that would allow vehicles to be charged on the road while in motion. It would essentially turn U.S. roadways into wireless chargers. Afrindi says he has been working on the tech for the last seven years. Here's how it would work, according to Afrindi via Business Insider: "'Highways would have a charging lane, sort of like a high occupancy lane,' Afridi told Insider. 'If you were running out of battery you would move into the charging lane. It would be able to identify which car went into the lane and it would later send you a bill.' The science behind Afridi's project goes back over 100 years to Nikola Tesla, the inventor who used alternating electric fields to power lights without plugging them in. Afridi's technology would embed special metal plates in the road that are connected to a powerline and a high frequency inverter. The plates will create alternating electric fields that attract and repel a pair of matching plates attached to the bottom of the EV.No need to worry about stopping to charge unless you're down for the night. They have run into a problem, however. They can't seem to find the parts that can handle the high levels of power needed to charge vehicles enough while they are in motion. It would have to be a material that's not only weatherproof but able to withstand high voltage and heat from the passing vehicles."
