Earlier this year, a relatively unknown startup from Finland made a startling announcement: It had finally solved solid-state batteries.
Technology
Is the ‘Holy Grail of batteries’ finally ready to bless us with its presence?
Not only that, but Donut Lab, a spinoff of Verge Motorcycles, said that its solid-state battery — long considered the “Holy Grail of batteries” for their high-density, durable, fast-charging abilities — would go into production later this year.
Battery experts were understandably skeptical. After all, solid-state batteries are one of those technologies, along with artificial general intelligence and the hyperloop, that seem perpetually two years away. And while most legitimate efforts in this field — whether academic or commercial — have some level of published research or recognizable names attached, Donut Lab seemed to have emerged out of nowhere, with no known researchers or prior presence in the field. This lack of traceability immediately raised concerns about the startup’s credibility.
“I can’t say they didn’t do it,” said Eric Wachsman, the director of the Maryland Energy Innovation Institute and an expert on solid-state batteries and solid oxide fuel cells. “All I can say is they haven’t demonstrated that they have.”
The skepticism seems warranted, especially when you consider how many other people have been chasing the solid-state dream. Were we really to believe this obscure startup had beaten Toyota, Stellantis, and the entire nation of China to the punch? The odds were against it.
Donut Lab seemed to anticipate the doubt, launching a website last February called idonutbelieve.com that would serve as a platform to publish independent tests verifying that, in fact, its solid-state battery was real, and spectacular. Over the course of several weeks, the startup posted third-party results from state-owned VTT Technical Research Centre of Finland that it said proved its battery was what it said it was: a fast-charging, high-energy-density solid-state battery that wasn’t actually a supercapacitor in disguise.
“The resistance won’t disappear when we present the proof,” Donut Lab CEO and cofounder Marko Lehtimäki said in a video. “It will just intensify because this new technology is a threat to the established players in the industry.”
But Donut Lab is still hiding the ball on some key information. At CES in January, the startup said its solid-state battery has an energy density of 400Wh per kilogram—roughly twice that of typical lithium iron phosphate (LFP) batteries in production. Not only that, but it could charge to full in five minutes, had a practically unlimited lifespan of 100,000 charging cycles, was unaffected by heat and cold (negative 30 degrees Celsius and 100C), and contains no rare earth elements, precious metals, or flammable liquid electrolytes.
Much of that remains unsubstantiated. Even after posting five independent test reports from VTT, the startup has yet to demonstrate three of the most important metrics: chemistry, density, and cycle-life claims.
The stakes are incredibly high. Imagine an electric vehicle that can travel 700–800 miles on a single charge, and that wasn’t at risk of bursting into flames because the flammable electrolytes had been replaced with a solid material.
In lithium-ion batteries, the motion of the liquid electrolytes generates heat, and in certain situations, this can slip into a “thermal runaway” effect that results in a fire. By comparison, solid-state batteries would make it safer to quickly draw power from (or add it back to) the battery, meaning you could theoretically charge an EV faster. It also could mean, structurally, less room has to be devoted to temperature control, which could allow companies to squeeze more battery cells into the same size pack.
After reviewing the tests of the Donut battery, Wachsman said there are still significant concerns. During the extreme heat tests, for example, the pouch surrounding Donut’s battery lost its vacuum seal. Gas generation inside batteries — caused by processes like electrolyte decomposition or oxygen release — can lead to swelling and rupture of the battery pouch. But without knowing the exact chemistry of the cell, it’s difficult to say how significant it is that Donut’s battery had this failure.
Setting aside the Donut battery for a moment, solid-state batteries have struggled to graduate from the laboratory to the assembly line because of well-documented problems. These batteries are often plagued by the formation of metallic cracks called dendrites that cause them to short circuit. Think of them like cracks that form on a sidewalk when a tree root grows underneath.
Dendrites have been a thorn in the side of battery developers since the 1970s. One reason lithium-ion batteries have become ubiquitous while other approaches have stalled is that their commonly used graphite anodes are less susceptible to dendrite formation.
But new discoveries could help engineers finally overcome these hurdles. A research team from MIT recently published a study in Nature that found that chemical reactions caused by high electrical currents that weaken the electrolyte also make it more susceptible to dendrite growth. That’s why developing stronger electrolytes alone hasn’t solved the decades-old dendrite problem. And it could point to the importance of developing more chemically stable materials to finally fulfill the promise of solid-state batteries.
Progress is already being made — where else? — in China. Last month, CATL, which controls nearly 40 percent of the global battery market, filed a patent application for solid-state batteries with a reported 500Wh energy density. According to CarNewsChina, the battery maker has already been planning small-scale production in 2027. But automotive-grade cells won’t be ready likely until the end of the decade.
Other Chinese companies are rushing ahead. Automaker FAW said recently that its “liquid-solid-state” lithium-rich manganese cell with 500Wh/kg was ready for vehicle integration.
China is already laying the groundwork for mass production by the end of the decade, by which point it hopes the technology will be mature. And why wouldn’t it? This is a country that has taken EVs and battery development seriously for years, allowing it to corner the market on much of the world’s supply.
Different companies are taking different approaches. For example, Honda is committed to sulfur-based electrolytes despite emerging alternatives. Last October, Toyota announced “the world’s first practical use of all-solid-state batteries in BEVs” by 2027 or 2028. And Mercedes, using a prototype battery from startup Factorial, was able to get an electric EQS sedan a real-world range of 749 miles.
“The companies probably have a ways to go,” said Alevtina Smirnova, director of the NSF Industry-University Cooperative Research Center for Solid-State Electric Power Storage. “Because there is no comparison to what is happening now in China to what is happening here in the US.”
For its part, Donut Lab is unperturbed by the skepticism around its claims. On April 1st, Lehtimäki posted a new video addressing some of the controversy surrounding its solid-state batteries. He also revealed that Donut Lab had created a second, more production-ready version of its battery that would start shipping to customers later this year.
There was a crucial admission: The widely discussed “100,000 cycles” figure was a design target, he said, not an experimentally verified result. Actual testing has been conducted over shorter cycles, with projections extrapolated based on known variables such as charge rate, temperature, and usage conditions.
He then pivoted to a more near-term project: Donut Lab’s latest merch drop, including a “tin-foil”-covered bucket hat.

Valve has some good news and bad news about Steam Controllers. The good news: if you make a reservation for a Steam Controller, the company will now show you one of three estimates of when you’ll be able to actually order your gamepad: by September 2026, by December 2026, or sometime in 2027. The bad news: any reservations made today “indicate a 2027 date for shipping,” Valve says.
“We have no plans to stop making Steam Controller,” according to Valve. “But as we look at the current demand compared to how many we know we can make by the end of the year, we want to manage expectations as much as we can with regards to when folks can expect to receive their order.”
Valve’s very good new Steam Controller went on sale in early May, and the initial rush led some people to run into frustrating problems with trying to check out ahead of the controllers eventually going out of stock. A few days later, the company announced that it would be implementing a reservations queue for interested buyers so they could get on a waitlist. If you’re on the waitlist, when you get notified that a Steam Controller is ready for you to buy, you have 72 hours to actually make the order.
“When we launched Steam Controller last month, we quickly saw that initial demand exceeded our expectations,” Valve says. “Switching to a reservation queue has (hopefully) cut down on the headaches on the customer side, and for us it’s also been helpful as we plan ahead and try to get as many out as quickly as we are able.”
All three of Valve’s big hardware products were delayed from a planned early 2026 launch because of the component crisis, Valve still hasn’t announced when the Steam Machine PC or Steam Frame VR headset might go on sale. However, just yesterday, Valve officially launched its big SteamOS 3.8 update with support for the Steam Machine. It’s also been importing a lot of hardware into the US as of late.

The next time you pull up to a McDonald’s drive-thru, the voice taking your order may not be human. McDonald’s is testing a new AI-powered system called ArchIQ at five U.S. locations. The company has not said where those restaurants are located. The voice assistant, nicknamed Archy, can take drive-thru orders and has shown it can handle both English and Spanish.
For anyone who has repeated “no pickles” into a speaker box more than once, this could sound helpful. However, if you remember McDonald’s last AI drive-thru experiment, you may also wonder whether your burger order could somehow turn into a bag full of surprise McNuggets.

WOULD YOU EAT AT A RESTAURANT RUN BY AI?

What is McDonald’s AI drive-thru?
ArchIQ is McDonald’s new AI system for restaurants. It can take drive-thru orders and also help with operations behind the scenes.
In a post on X, McFranchisee, an anonymous McDonald’s franchisee account, said the system is currently in five test stores and has processed more than one million transactions. The account also said about 90% of orders were completed without a human stepping in. That number sounds promising. Still, McDonald’s has not confirmed a nationwide launch date. For now, this remains a limited test.
The system also appears to connect with a bigger McDonald’s plan called “McDonald’s > NEXT.” CEO Chris Kempczinski described the strategy as a way to bring in more customers and improve restaurant productivity. The plan also includes menu changes, restaurant redesigns, technology upgrades and more focus on hospitality.
Why McDonald’s is testing AI ordering
Drive-thrus can get chaotic fast. Someone changes an order after the total appears. A child calls out from the back seat. Road noise makes the speaker hard to hear. Then the driver remembers the extra sauce after everything has already gone through. That is the type of pressure McDonald’s wants AI to handle.
If ArchIQ works well, it could help restaurants move cars through the line faster. It may also reduce mistakes during busy hours. Workers could then focus more on preparing food, handling payments and helping customers who need a real person.
ArchIQ also appears to have a management role. In the same X post, McFranchisee described Archy as a tool that could alert managers to bottlenecks or other issues before they slow down operations.

McDonald’s tried AI drive-thru ordering before
This new test follows McDonald’s earlier AI drive-thru experiment with IBM. That program involved more than 100 restaurants. McDonald’s ended the test in 2024 after customers complained about order accuracy. Some mistakes also went viral, creating an embarrassing moment for McDonald’s and raising questions about whether the technology was ready for the drive-thru. Customers reported wrong items, strange quantities and other order mix-ups. That history is why this new test will get extra attention.
This time, McDonald’s is working with Google technology. McFranchisee also claimed every McDonald’s in the U.S. is getting Google Edge Cloud hardware in anticipation of the rollout. McDonald’s seems to believe the newer system can perform better than the last one. The real test will come when regular customers use it during real drive-thru rushes.
How McDonald’s AI drive-thru could help customers
If McDonald’s gets this right, the most obvious benefit is speed. An AI ordering system does not get tired during a long shift. It may also help more customers order in the language they prefer. That could make a busy drive-thru feel less frustrating, especially during breakfast or late-night hours.
The system may also ask clearer follow-up questions and catch missing details before the order reaches the kitchen. That would be a win for customers who want to get in, get their food and get on with the day.
The biggest problem with AI drive-thru orders
The biggest concern is accuracy. AI can still misunderstand people. That gets frustrating fast when you are trying to grab lunch between errands or get your kids fed from the back seat. A wrong order wastes time. It also puts workers in the position of fixing a mistake the machine made.
There is also the customer service side. Some people like hearing a real person at the speaker. Others may find an AI voice cold or annoying, especially if the system gets confused.
Then there is the privacy question. If an AI system takes your order, customers may wonder what gets collected, how long it is kept and who can access it. McDonald’s has not publicly explained those specifics for this current ArchIQ test.
ALEXA+ LETS YOU ORDER FOOD LIKE A REAL CONVERSATION

How to avoid AI drive-thru mistakes
Before you leave the drive-thru, take a moment to check the order screen. Make sure the items match what you said. Listen when the system repeats your order. Keep your receipt until you confirm the food is right.
Also, avoid sharing extra personal details at the speaker box. Your order should only require your food choices and payment.
If the AI gets confused, ask for a crew member. You do not need to keep going back and forth with a machine over fries.
What this means for you
For now, you probably will not notice a change at your local McDonald’s. The ArchIQ test appears limited to five U.S. restaurants, and the company has not said when it could expand.
Still, this gives customers a preview of where fast food may be heading. AI could soon play a bigger role in how restaurants take orders and manage the kitchen. That may speed up the line, though it could also make the experience feel less personal.

Kurt’s key takeaways
McDonald’s clearly wants AI to play a bigger role in its restaurants. From a business point of view, the idea makes sense. Shorter drive-thru lines could help franchisees and customers. Better restaurant data could also help managers fix problems faster. But I still want the human backup. Food orders can be messy because people are messy. We change our minds. We talk over each other. We forget the extra ketchup until the last second. AI may handle much of that one day. For now, I would treat it like any busy drive-thru interaction. Speak clearly. Check the order. Do not pull away until you know your food is right.

Midjourney CEO David Holz just showed off the company’s first hardware product and plans to build a San Francisco spa, which he admitted is a bit different from the “cat pictures” produced by its AI image generator. Dubbed The Midjourney Scanner, it’s an ultrasound-based full-body scanner that uses a ring of sensors to capture vertical slices of the inside of your body, looking at the composition of your muscle, fat, bone, and organs to start. Holz said ideally, you could do this once a year or every single day, as it “aims for image quality comparable to MRI in many ways.”
He mentioned that one way he’d like to use it would be to see how his body changes in response to diet and workout changes, saying, “I’m not the most measured man on Earth yet, you know, but maybe I want to have that daily [measurable information].” A set of job listings advertises the company’s goal as trying to “build and launch the world’s first full-body ultrasound CT scanner, ultimately bringing safe, fast, and high fidelity preventative scanning to billions via a magical spa experience.”
The Midjourney Scanner was developed in a partnership with ultrasound tech company Butterfly Network, which said it uses “40 Butterfly Ultrasound-on-Chip imaging modules per system.”
The scanning process starts with stepping onto a platform that drops down into the water on rails through a ring of thousands of transducers that create ultrasonic waves. It then records the ripples passing through your body to analyze them and create detailed 3D images. The scan takes about 60 seconds. Holz said about a dozen people have been scanned so far.
It starts by stepping into a shallow pool of golden light. You then begin to descend into the water. Your body passes through a ring of underwater sensors, each acting like a dolphin, using its echolocation. The sensors send ultrasonic sound waves through your body from every angle. With enough waves, and enough angles, we form an image of what’s happening inside your body.
It combines those sensors with two petaflops of processing power. But after watching the livestreamed reveal, I’m still unclear on what Midjourney’s AI image generation tech exactly has to do with the Midjourney Medical effort, beyond an alternative business for otherwise-unused AI compute.
Holz hopes to put 10 of the scanners into a Midjourney Spa location in San Francisco’s Union Square that will open before the end of 2027 and offered to scan the hands of attendees at its launch event. The Midjourney Spa will have a gym, saunas, and cold plunges to go along with the hot tub–equipped scanning rooms where visitors will get into the water to be scanned.
He did mention that various medical applications would require FDA clearances, but for now, Midjourney Medical says it’s working on “body composition maps” that don’t require the same level of clearance as diagnostic imaging. It also says the “library of scans” users create can be shared with doctors, AI health tools, or others, and that, “We take data privacy seriously — more details on our data policies will come as we get closer to launch.”
Holz suggested that eventually these scans could become better than an MRI, without radiation, powerful magnets, or other complicating factors, to get a look at what’s going on inside people’s bodies “real fast.” In response to a question, he imagined a future where the FDA had a class of devices to look at “weird” things and allowed people to “just try to get as much data as we can.”
