What happens to an electric vehicle's big slab of batteries once it no longer holds a sufficient charge? On Thursday, Redwood Materials moved that conversation forward with an announcement that it has started its EV battery recycling program, with Ford and Volvo as partners.
US law requires an EV's traction battery to maintain at least 70 percent of its original state of charge after eight years or 100,000 miles. Even older EVs—ones with proper thermal management for the battery pack—are showing resilience to battery degradation over time.
But eventually, a pack will no longer be suitable for propelling a car, at which point it can be given a second life as static storage. After the battery degrades enough, it's time for recycling.

The first laptops with Intel Arc discrete graphics are expected to begin shipping before the end of March, and now Intel says we can expect to see the first Intel Arc graphics cards for desktop computers in the second quarter of the year with workstation-class GPUs coming in Q3, 2022.
All told, the company says it expects to ship more than 4 million discrete GPUs this year. The chip maker is also laying out a roadmap that promises at least two more big launches coming later on.
One is a previously undisclosed GPU in the cloud service code-named “Project Endgame,” which Intel says “will enable user to access Intel Arc GPUs through a service for always-accessible, low-latency computing experience.”
This sounds a lot like it could be Intel’s answer to NVIDIA’s GeForce Now game streaming service, which basically lets gamers leverage NVIDIA’s cloud-based servers to play games on a phone or PC with entry-level hardware that might not otherwise be able to handle things like ray-tracing or gaming on a 120 Hz display.
It’s unclear if Project Endgame will be similarly focused on gaming though, or if Intel plans to leverage its GPU-in-the-cloud service for other tasks. The company says Project Endgame will launch later in 2022.
The company also says its begun designing a new GPU architecture code-named “Celestial,” which is designed for the “ultra-enthusiast segment,” suggesting that while the company’s first discrete GPUs (code-named “Alchemist”) may not exactly be NVIDIA RTX 3080 killers, the company does expect to play in that space eventually.
More importantly, given the impact global supply chain issues have had on the availability of NVIDIA and AMD GPUs, the fact that Intel expects to ship any discrete GPUs at all this year is probably good news for folks looking for a bit more graphics horsepower than they can get from systems with integrated graphics alone.
For over a decade, the US has blended ethanol with gasoline in an attempt to reduce the overall carbon pollution produced by fossil fuel-powered cars and trucks. But a new study says that the practice may not be achieving its goals. In fact, burning ethanol made from corn—the major source in the US—may be worse for the climate than just burning gasoline alone.
Corn drove demand for land and fertilizer far higher than previous assessments had estimated. Together, the additional land and fertilizer drove up ethanol’s carbon footprint to the point where the lifecycle greenhouse gas emissions—from seed to tank—were higher than that of gasoline. Some researchers predicted this might happen, but the new paper provides a comprehensive and retrospective look at the real-world results of the policy.
Proponents have long argued that corn-based ethanol bolsters farm incomes while providing a domestic source of renewable liquid fuel, while critics have said that its status as a carbon-reducing gasoline additive relies on questionable accounting. Based on the new study, both sides may be right.

Now that Windows 11's first major post-release update has been issued, Microsoft has started testing a huge collection of new features, UI changes, and redesigned apps in the latest Windows Insider preview for Dev channel users. By and large, the changes are significant and useful—there's an overhauled Task Manager, folders for pinned apps in the Start menu, the renewed ability to drag items into the Taskbar (as you could in Windows 10), improvements to the Do Not Disturb and Focus modes, new touchscreen gestures, and a long list of other fixes and enhancements.
But tucked away toward the bottom of the changelog is one unwelcome addition: Like the Home edition of Windows 11, the Pro version will now require an Internet connection and a Microsoft Account during setup. In the current version of Windows 11, you could still create a local user account during setup by not connecting your PC to the Internet—something that also worked in the Home version of Windows 10 but was removed in 11. That workaround will no longer be available in either edition going forward, barring a change in Microsoft's plans.
While most devices do require a sign-in to fully enable app stores, cloud storage, and cross-device sharing and syncing, Windows 11 will soon stand alone as the only major consumer OS that requires account sign-in to enable even basic functionality. Apple's Macs still allow for local account creation during setup, and you can skip signing in when you set up iPhones and iPads (an Internet connection is sometimes required for device activation, though). Android likewise needs an Internet account for activation but doesn't require signing in to get you to the home screen. Even Chrome OS has a guest mode that you can use to enable basic browsing without a user account.

Porsche's next race car is so new that it still doesn't have an official name. It's not even due to enter its first race for more than 11 months. But there are few things Porsche takes more seriously than a racing program, particularly one that has a good chance of victory at significant races in Daytona, Sebring, and Le Mans. That's why the car has already completed its first test at the Circuit de Catalunya near Barcelona, Spain.
After all, this new car, built for a new "hypercar" class in the IMSA's WeatherTech championship and the FIA's World Endurance Championship, has a lot to live up to. Porsche has had 22 overall wins in the Rolex 24 at Daytona, 18 overall wins at the 12 Hours of Sebring, and 19 overall wins at the 24 Hours of Le Mans.
"We're the first to put an LMDh vehicle through its paces in test mode," said Jonathan Diuguid, managing director of Porsche Penske Motorsport. "This gives us the chance to systematically sort out every aspect over the coming weeks and months and to take on the competition in 2023 with the best possible preparation."

The first laptops powered by AMD’s Ryzen 6000 mobile processors should arrive soon with new models on the way from Acer, Asus, Dell (Alienware), Lenovo, Razer, and others. While AMD’s 2022 mobile chip lineup will eventually include a wide range of processors including 15-watt U-series chips and 45+ watt Ryzen 6000HX series processors, the first laptops to hit the streets will be powered by 35-watt HX series processors.
For the most part, AMD’s new chips seem to offer a modest boost in CPU performance when compared with their Ryzen 5000 counterparts. But AMD has moved from a 7nm manufacturing process to 6nm, bringing improved density and efficiency.
Tom’s Hardware reports that while CPU performance gains measured in the single-digit percentages might sound underwhelming at a time when Intel’s 12th-gen Core H-series chips are delivering much bigger gains, AMD seems confident that its approach is more efficient than Intel’s, which will allow the same CPU architecture to scale well to energy-efficient U-series chips and high-performance H-series processor while allowing for long battery life.
Intel’s 12th-gen “Alder Lake” processors use a hybrid architecture that combines high-performance CPU cores with energy-efficient cores, allowing a PC to use just the cores that are needed for a certain task or to fire up all the cores at once. AMD says it’s only using high-performance cores, but they offer the kind of efficiency needed to balance power consumption and battery life in laptops.

That said, Tom’s Hardware notes that some of AMD’s claims seem a bit questionable, stating that a Ryzen 9 6900HS processor is up to 2.62X more efficient than a Core i9-12900HK because the former tops out at 35-watts during sustained performance while the later can go as high as 110 watts… but it’s highly unlikely that any laptops will actually have the cooling capabilities to allow Intel’s chip to stay at 110 watts for very long.
Anyway, while it remains to be seen whether AMD’s 6000 chips will be truly competitive with Intel’s Alder Lake processors this year when it comes to CPU performance, AMD will most likely take the lead when it comes to integrated graphics performance.
For the past few years AMD has been using its Radeon Vega architecture for integrated graphics. This year’s chips ship with Radeon 600M graphics based on RDNA 2 architecture and according to the company’s own benchmarks, not only does it outperform Intel’s Iris Xe graphics in gaming benchmarks, but it comes close to NVIDIA’s GeForce RTX 1650 discrete GPU.
Right now it seems like Intel may have the edge in CPU performance, while AMD is taking the lead in integrated graphics. But it’s unclear if that will continue to be the case as the companies release more chips: so far we’ve only seen independent reviews of devices powered by H-series processors, and it’s possible that they won’t be reflective of the more energy-efficient U-series chips set to launch later this year.
We may have to wait a little while to see laptops that truly take advantage of AMD’s new integrated GPU because the first laptops to ship will have Ryzen 6000HS chips paired with discrete graphics from AMD or NVIDIA. While the integrated graphics will likely handle some tasks, those discrete GPUs will most likely kick in when you need them most for things like gaming, graphic design, or video editing.
