Inertia Enterprises finds a way to make its fusion fuel fast
Fusion startup Inertia Enterprises said it has found a way to cut the time it takes to make its fuel pellets from several days to just minutes.
By slashing fuel filling time, Inertia says it has knocked down one of the ten barriers it must overcome to deliver the first phase of its commercial power plant ambitions. The startup gave TechCrunch an exclusive first look at the process.
The advance was not guaranteed: Investors gave Inertia $450 million on the premise that it could commercialize technology developed at the National Ignition Facility (NIF), which is an elaborate science experiment that requires painstaking care and feeding to operate. At the NIF, making fuel pellets can take a week or more and cost a small fortune. That’s not a great recipe for a profitable operation.
“But when you really double-click on it, you’re like, wait a minute, they’re only making a handful of them a year,” Jeff Lawson, co-founder and CEO of Inertia, told TechCrunch. “I put on my commercial hat and was like, wait a minute, I know the word for this: Prototypes.”
At Inertia, the team set about turning those prototypes into something mass manufacturable. “That’s why we’re hiring people from the likes of Apple,” he said. “There’s a bunch of industrial engineers who are like, ‘Alright, I guess I have to go figure out how to make that a billion times over in a factory.’”
NIF’s fuel pellet is far from an iPhone, though. The outside is a spherical diamond shell, and just inside, there’s a thin layer of frozen deuterium and tritium, the isotopes of hydrogen that can fuel a fusion reactor. Inside the crystalline layer lies a mix of gaseous deuterium and tritium. Each solid layer must be as close to perfectly spherical as possible.
Those fuel pellets are then wrapped in gold casings known as hohlraums, which convert laser energy into X-rays that compress the fuel pellet inside. If everything goes to plan, that compression causes atoms to fuse and release energy. But even small imperfections in the spherical shape can disrupt the ignition process, preventing a fusion reaction from reaching its full potential.
Inertia had to condense the process to the point where it makes commercial sense without straying too far from the physics discovered at NIF.
“What happens if you try to do it faster?” Lawson said. The team had a head start: Annie Kritcher, co-founder and chief scientist at Inertia, designed the first fusion experiment at NIF that released more power than it consumed.
After several rounds of development, the startup was able to grow the crystals in about 30 minutes, something that could take up to a week at NIF. Altogether, a single fuel pellet can be made in about two to three hours, and the process can be ramped to industrial scale. Inertia developed the process with help from the NIF at the Lawrence Livermore National Lab, with which the startup has formed a public-private partnership.
Inertia has an advantage that NIF does not, though. Because the startup is planning to use a laser that is four times more powerful than the one currently at the NIF, it can tolerate more imperfections in the fuel pellet. This also helped speed the manufacturing process.
“We actually have a lot of margin,” Lawson said. “That’s our strategy, to oversize our driver, our laser, to give us lots of margin to go play with in every other part of the system.”
Reducing fuel filling time has the knock-on effect of reducing the amount of tritium Inertia needs to hold at any given time. Tritium is radioactive, and handling it requires care. It’s also extremely expensive at the moment, about $30,000 per gram, and only about 25 kilograms are stockpiled globally, according to the journal Science.
Inertia, like many fusion startups, plans to make its own tritium with help from the fusion reactions, but it still needs some inventory to get started. Plus, reducing manufacturing time helps keep inventory small. Inertia expects its full-scale commercial power plant will use ten fuel pellets every second.
“By reducing the latency of this step, you’ve made your facility smaller; you’ve made the whole thing faster, the whole thing more efficient,” Lawson said.

Patreon launches 30 new creator features, including short-form Clips and revamped discovery
The team at Patreon, the membership platform for creators, has been building like crazy and is now revealing the result. On Thursday, the company debuted dozens of new features to help creators get discovered, build their community, learn from insights, and more.
Patreon says its roadmap is meant to reflect the core philosophy that today’s internet has failed creators by prioritizing fleeting engagement over genuine community, making it hard for creators to be fairly paid.
“The current version of the web is a failed promise for creators and fandoms. As creators, we can’t even reach our followers on the platforms anymore,” wrote Patreon CEO Jack Conte in an announcement about the new features. “Social media has created mass polarization, addiction, and made it increasingly difficult to build a creative community and business. I refuse to believe that this is the best or only way that the internet can work for creators and fans. I believe it can and should be better,” he added.
Patreon’s changes, however, acknowledge the role that short-form video platforms, like TikTok or Reels, play in helping creators find an audience.
To make that discovery easier, it’s rolling out a feature on iOS called Clips, which will turn creators’ videos into short, shareable clips. These can be downloaded and shared off-platform, as on TikTok, or posted as Patreon’s own short-form post format, known as Quip.

Plus, creators will be able to leverage new tools that offer potential fans more previews of their work.
The tools, which are still in early testing, include suggested video previews, which will pull out the most engaging parts of their paid videos, and another that lets creators quote snippets of their longer written posts into Quips. The video previews can be shown to fans who are weighing whether or not to pay to unlock the content or subscribe to a membership, while the text-based, quote Quips can be shared as previews to the Home feed, offering creators more exposure.

Native video and Quips are also now rolling out to creators of adult (18+) content.
Another significant change in today’s update involves Patreon’s discovery algorithm.
Before, the company’s recommendation systems focused on finding creators similar to those the user already liked, but it tended to favor larger creators. Now, discovery will focus more on comparing a particular post to other posts by topic, craft, style, theme, and other factors. Patreon says this will help to highlight smaller creators, too.

The company is also rolling out several new features designed to deepen fandoms and help make Patreon more of a destination.
The highlight here is a new communities feature called Niches, which allows creators to participate in dedicated, topic-based communities built around specific interests, subcultures, or fandoms. This could help fans discover more of what they like, without needing to dig around the site to find all the different creators focused on the topic at hand.

Patreon will also roll out other tools, like support for Live Q&As on creator livestreams, and tools that let fans make their own profiles. (Those profiles and the communities are now in early testing, while the Live Q&As are now arriving.)


Another set of tools will help creators track their audience and earnings, which can be key to developing a healthy fandom.
Patreon is launching more granular earnings, membership, and growth analytics, with an earnings tab that breaks down earnings by tier and billing cadence. The platform is also adding membership insights, like member counts that show free trials and members in payment retry, plus filters to break down memberships by trial, gift, active, and retrying status.


A revamped version of the Payouts tab will also show creators a complete record of the earnings moving in and out of their account.
Soon, Patreon will also add creator milestones, or key growth moments, to celebrate special moments in terms of the growth of their community.
As part of its longer-term roadmap, Patreon plans to develop security features like anti-AI scraping tools, real-time spam detection, expanded auto-moderation, additional verification measures, and more.
The full list of improvements includes thirty new or revamped features, some of which are still in early testing. Over the next few months, creators should expect to see many more changes arrive, Patreon said.

Meta brings Pocket, an app that lets you vibe-code and share games, to US users
Meta’s experimental vibe-coding gaming app, Pocket, is now rolling out to everyone in the U.S. The app, which arrived quietly last month in the test market of Brazil, allows people to generate small, interactive games using AI prompts, which are published to a scrollable feed.
Based on Meta’s acqui-hire of the team at the vibe-coded gaming platform Gizmo earlier this year, these games — or “gizmos” as they’re called — respond to touch and the tilt of your phone, play sound effects, and can include clips of your favorite songs.
They can also use photos from your camera roll or access your camera. The resulting games can then be shared on your profile, where others can save them, remix them into other creations, or simply repost them.

The app is the latest example of Meta’s push to make AI creation tools mainstream, following its earlier efforts that included making AI-generated images with its Meta AI app as well as AI videos created with an experimental app called Vibes.
Pocket now joins these and several other standalone mobile applications from Meta in recent months. CEO Mark Zuckerberg has credited the increased output to AI-enabled software development, which makes it faster for the company to test and ship new ideas.
“Earlier this year, we shipped Instagram Instants. We also just launched Forum, a stand-alone Groups app, and Seller, a stand-alone Marketplace app. I expect it to become a lot easier to ship new apps,” he told analysts on July’s earnings call. “So we are planning to build out more ideas and use our recommendation systems to scale them.”
In addition to Instants, Forum, and the Seller app, Meta has shipped an experiment involving AI bedtime stories, and this week, a Meta AI app for Mac.
