Marvel Fusion lands $70M for laser-powered fusion bet

Published

on

A scientist oversees a laser experiment.

When it comes to fusion power, there are two basic approaches: One, create a small star here on Earth that’s held in place by powerful magnetic fields. Two, use intense lasers to make a succession of even smaller stars, but repeat the process several times per second.

Moritz von der Linden likes his odds with the latter. In a world racing to wean itself off fossil fuels, fusion power promises to be an effectively limitless supply of energy, using widely available materials to recreate conditions that are hotter than the surface of the sun.

But most analysts believe commercial fusion power is still at least a decade away, and it’s up against renewable energy and battery storage, which continue to grow cheaper by the year. “Fusion has to come fast and it has to come cheap,” the co-founder and CEO of Marvel Fusion told TechCrunch. “Otherwise nobody needs it, and nobody will be willing to pay for it.”

Marvel Fusion is one of several companies pursuing what’s known as inertial confinement fusion. It’s the same basic approach used at the National Ignition Facility, a Department of Energy lab which proved in 2022 that controlled fusion reactions could generate more power than it took to ignite them. That’s a helpful milestone for any startup chasing the thus-far elusive technology.

But where NIF’s lasers are based on decades-old designs, Marvel is using cutting-edge technology to improve its lasers’ power and efficiency. The startup will soon build a demonstration facility in collaboration with Colorado State University, where it hopes two 100-Joule lasers will prove its core technology. Shovels hit the dirt on October 16, and von der Linden expects it’ll be operational by early 2027.

Those lasers will fire faster than the blink of an eye — in the femtosecond range, or one billionth of second — bombarding a nanostructured target with photons that blast away its electrons and scatter the remaining positively charged ions. Those ions will then hit Marvel’s fuel, igniting a fusion reaction. Currently, the company is using a mix of mainly hydrogen and boron, though von der Linden says the company is taking a “mixed fuel” approach to keep its options open should a more advantageous combination come along.

Compared with NIF’s fuel pellet, which is ensconced in a one-centimeter gold hohlraum that takes two weeks to manufacture and load, Marvel’s fuel and target were designed for mass manufacturing. The fuel itself is solid at room temperature, making it simpler to handle than NIF’s fel, which relies on either gaseous or cryogenically frozen hydrogen isotopes. Marvel’s target is simpler, too, made of silicon, not gold.

“That was kind of an awakening,” von der Linden said. “When the physics guys found out silicon works better, the target guys were like, ‘Hallelujah! We can use standard lithography from chip manufacturing.’” At the dimensions Marvel intends to manufacture, about 50 to 80 nanometers per feature, the company can use semiconductor manufacturing equipment that’s up to a decade old. It can produce around 5,000 targets on a standard 300 millimeter wafer.

If the Colorado experiments go as planned, the company will increase both lasers’ energy in 2028 or 2029. To hit those milestones, Marvel recently raised €62.8 million in a Series B round, the company exclusively told TechCrunch. HV Capital led the round with participation from b2venture, BayernKapital, Deutsche Telekom, SPRIND, and Tenglemann Ventures. The company was also selected by the European Innovation Council for a €2.5 million grant and up to €15 million in equity investment, which if made will be an extension of this round.

Marvel’s first commercial-scale prototype should be finalized around 2032 or 2033, von der Linden said, and it will contain between 10 and 20 two-kilojoule lasers. “With 20 lasers, we have the ability to really engineer the acceleration of the ions.” Each will fire around ten times per second.

That’ll be the moment of truth. While the company’s Colorado facility will be a useful milestone, “it’s like driving a Ferrari with a two cylinder engine,” von der Linden said. “It will move, but it won’t do what it’s supposed to do,” which in Marvel’s case is generate useful amounts of power. If the full-scale prototype fires on all, er, lasers, then the startup has a chance of crossing the fusion finish line. The race is on.

Galaxy Tab S10 accessories are cross-compatible with the Tab S9 (with one caveat)

Published

on

AI will shape every aspect of daily life, Samsung’s AI life

Samsung has ensured that the latest Galaxy Tab S10 accessories are cross-compatible with the previous generation. Accessories for the Samsung Galaxy Tab S9 will also work on the new tablets. There’s however, one minor but glaring limitation.

Galaxy Tab S10 and Tab S9 accessories are cross-compatible

Samsung officially announced the Galaxy Tab S10 series on Thursday. Just as predicted in the leaks, Samsung is offering just two variants of the tablet this year: the Galaxy Tab S10 Plus and Galaxy Tab S10 Ultra.

What’s surprising, other than the pricing of the tablets, is the fact that their accessories can reportedly work with the previous generation of the Galaxy Tab, and vice versa. In other words, Galaxy Tab S9 users can slap their accessories onto the new Tab S10. So, those who upgraded to the latest Galaxy Tab S10 can continue using the Tab S9 accessories.

This is an important decision consideration from two perspectives. First, the Galaxy Tab S9 accessories needn’t be discarded. This is a win for reducing e-waste.

Secondly, Samsung may follow this design philosophy for future generations of its premium tablets, and perhaps smartphones as well. This wasn’t the case with the previous generation of Samsung Galaxy tablet models. Specifically speaking, accessories made for the Galaxy Tab S8, such as Book Covers and Book Keyboard Covers, are incompatible with the Galaxy Tab S9 series.

What’s concerning is that Samsung could have ensured cross-compatibility between the Tab S8 and the Tab S9 accessories. However, the company altered the location of the camera as well as the S Pen on the newer tablet models, eliminating the possibility of reusing accessories.

Should Samsung Galaxy Tab S10 users reuse their Tab S9 accessories?

The Galaxy Tab S9 launched just last year, so its accessories might not have experienced severe wear. It makes perfect sense to continue using them. It is, however, important to note that there’s no base Galaxy Tab S10 model.

Galaxy Tab S9 accessories are too small to fit the larger Galaxy Tab S10+ and Tab S10 Ultra. So, if you’re moving to a Galaxy Tab S10 model from the base Galaxy Tab S9, then you’re going to have to buy new accessories.

What’s the caveat?

There’s one more minor, but quite noticeable, limitation. The older Galaxy Tab S9 Keyboard Cover has a “Lang” key. Samsung replaced this key with a new “Galaxy AI” button on the 2024 Keyboard Covers. Pressing this key brings up Google Gemini or Samsung Bixby.

What this means is that swapping the Keyboard Cover will render this key useless. Samsung might release an update that could switch the function of the key depending on the model of the tablet the Keyboard Cover is attached to. But for now, the Galaxy AI button won’t work on the older Galaxy Tab S9 models.

The best deals to shop ahead of the October Big Deal Days sale

Early deals ahead of the October Big Deal Days sale and everything we know so far

Amazon Prime Big Deal Days is back this year, returning on October 8 and 9. The “fall Prime Day” of sorts has served as the online retailer’s unofficial kickoff to the holiday shopping season for the past few years.

We expect most of the deals to be Prime exclusives, meaning you must be an active Prime subscriber to get the discounts. There are always a couple of deals available for everyone, though, so it’s worth perusing Amazon’s site even if you don’t pay for Prime. It’s also worth doing so now because we’ve found a number of solid early Prime Day deals already available. These are the best of the bunch; we’ll be updating this post regularly in the lead-up to October Prime Day, so check back for the latest deals.

In addition to discounts on iPads and Apple Watches, you can save a bit on the new AirPods 4 right now. AirTags have a slight discount as well, both in single and multi-packs.

It’s a safe bet that we’ll see even more Amazon gear discounted on October Prime Day, but for now, you can snag a Fire tablet on sale, as well as Ring and Blink security cameras for much cheaper than usual.

Early Prime Day deals on tech include discounts on robot vacuums, webcams, smart plugs and more. There are also wireless earbuds and smartphones that you can grab for cheap, along with storage gear and power banks.

While these discounts aren’t technically October Prime day tech deals, we’d be remiss not to mention them. While sales on streaming services are becoming more common, there isn’t as much rhyme or reason to them as there is to, say, Amazon’s Prime Day sale cycle. That said, if you see a discount on a service you’ve been meaning to try, it’s worthwhile to jump on it.

October Prime Day will be held on October 8 and 9 this year.

October Prime Day is a members-only sale event run by Amazon in which the online retailer has thousands of sales on its site that are exclusively available to those with an active Prime members.

October Prime Day will last two full days.

Most October Prime Day deals will not be revealed until the days of the event. However, in years past, we’ve seen everything from clothing to household essentials to outdoor gear go on sale during this event. Engadget cares most about tech deals, and in past fall Prime Days, we’ve seen things like phones, tablets, headphones, earbuds, robot vacuums, smart home gear and more receive deep discounts.

Yes, because most deals will be Prime exclusives. However, there are always a few decent deals available to all Amazon shoppers, so it’s worth checking out Amazon’s site during October Prime Day to see where you can save even if you don’t pay for Prime.

SocialAI is an entirely new way of talking to AI

Published

on

Steven Johnson on Google, NotebookLM, and AI research

Roughly a month ago, Michael Sayman realized he could finally build the app he’d been thinking about for years: a social network where everyone but you is an AI bot. Large language models are finally good enough and cheap enough that the experience might actually feel social and useful, and not like a gimmick or a game. And so, after years of waiting and months of testing the latest models, Sayman got to work.

The app he built is called SocialAI, and it has become something of a viral phenomenon since it launched. (All he’d tell me is that it was downloaded 20,000 times in the first couple of days — but says the number has gone up substantially since then.) Some people thought it seemed fun and useful; other people thought it felt deeply dystopian. Is a social network still a social network, they wondered, if you’re the only human present? Still others thought the whole thing was an art project of sorts, a social commentary on the state of the online world.

On this episode of The Vergecast, Sayman says it’s really all of the above. But most of all, it’s an attempt to build an entirely new way to interact with AI models. Instead of a chatbot, which tries to deliver you the single best response to your prompt, SocialAI offers you options and filters in the form of replies. When you respond to a bot, or favorite a reply, that teaches the model more about what you’re looking for — and lets you choose your own AI adventure instead of just hoping the model gets it right.

“Over the past 10 years, we’ve had social media giants iterating relentlessly,” Sayman says, “with all the data in the world, to try and perfect an interface where people can interact with as many people and points of view as possible, right?” SocialAI looks like Twitter or Threads, he says, not to trick you into forgetting all the reply guys are AI but because we all know exactly how social networks work. “It’s not social for the sake of the social network, but social for the sake of social interface.”

SocialAI is still in its very early stages, which you’ll be able to tell immediately from the quality of some of the replies. Still, Sayman says he’s already seeing encouraging usage and feedback — and he has lots of ideas about where to take the app next. The future of AI probably isn’t a text box, but it also probably isn’t exactly a Twitter clone, either. We talk through some of the features he’s planning on launching, how the interface might change over time, why he thinks of social network design as the new skeuomorphism, and whether there’s a business in SocialAI over time.

Ultimately, Sayman doesn’t think of SocialAI as a dystopian nightmare. The truly dystopian thing, he says, is the current state of things, in which you never know who’s human and who’s not, and everyone’s just posting through it all the time on increasingly dangerous and problematic platforms. “I’m not trying to replace the human to human connection,” he says. “I’m trying to help people find a way to have a secondary option when that human isn’t around for them, so that they don’t have to rush to social media.” Next time you need to vent, he hopes you might decide to tell the bots instead. They’ll be there for you.
