Through 62 presentations this week, researchers at CFS and our collaborators are shining a physics spotlight on our SPARC fusion demonstration machine — and how it paves the way for our ARC power plant. 1/4 #FusionEnergy

It’s time to detail the third of the six milestones every company must reach on the way to commercial fusion energy. Our CEO Bob Mumgaard laid these out last year in an open letter — a guide for outside observers to track how well fusion energy companies are doing (cfs.energy/news-and-med...). 1/3

With a one-time investment of $10 billion, the United States has a chance to reshape its energy future for the better. A few days ago, the @fusionindustry.bsky.social detailed just how the country should put that money to work. 1/6

Data is good. Publishing it is good. This paper from Sam Wurzel and Scot Hsu is a peer-reviewed scorecard that lets us all track the concrete progress on our commercialization milestones — the solid foundation that builds trust in the fusion energy industry. 1/3 #FusionEnergy

To get the first half of our vacuum vessel from Italy to the USA, we flew it on an Antonov An-124 Ruslan aircraft, an unusual 4-engine cargo plane with room for the 48-ton component. Unlike passenger planes, the nose of the An-124 hinges upward to load and unload cargo. #FusionEnergy #PlaneSpotting

"Fusion’s potential impact on global energy systems is profound. It offers energy independence by decoupling power generation from natural resources, making it ideal for urban centers and regions with limited land." 1/2 #FusionEnergy

Getting half of SPARC'S vacuum vessel to Devens, Massachusetts was no easy task. 1/2 #FusionEnergy

Big update: Half of our vacuum vessel, the very heart of our SPARC fusion machine, has landed in Devens, Massachusetts. #PowerMoves

Very excited to be able to talk about something I've been working on for a while now - we're working with Commonwealth Fusion Systems, IMO the leading fusion startup in the world, to take our work on AI and tokamaks and make it work at the frontier of fusion energy. deepmind.google/discover/blo...

Google is working with Commonwealth Fusion Systems again, though not in the way you might think. The tech company's DeepMind division is providing its AI tools to help the fusion startup maximize power from its forthcoming reactor. techcrunch.com/2025/10/16/t...

It’s time to bring the new computing power of AI to fusion energy. Today, Commonwealth Fusion Systems and Google DeepMind — giants in these two fields — revealed that we’ve joined forces to explore how AI can improve our SPARC fusion machine. blog.cfs.energy/with-ai-alli... 🧵 #FusionEnergy #AI

At CFS, we believe AI has the potential to break bottlenecks in traditional computing and accelerate fusion energy progress. At Tuesday's Special Competitive Studies Project conference about fusion and AI, our CEO Bob Mumgaard described how fusion could be one of many fields that AI could remake. 🧵

“The central dynamic of the fusion race is clear: the United States laid the scientific groundwork; China is positioning to win the industry…" So concludes a new report on the race to reap fusion energy's benefits: economic advantages, energy independence, a lead in AI & national security. 🧵

"I’m optimistic the ARC power plant will come online within the next decade. When that day comes, it will be a huge win for America’s energy independence—and for the world’s quest for abundant sustainable energy." 1/2 — Bill Gates #FusionEnergy

This week, we announced that a production version of our groundbreaking magnet technology passed our rigorous testing, clearing it for use in our SPARC fusion machine. The @energygov.bsky.social's Milestone program validated our tests, and awarded CFS $8 million for reaching the milestone.

Two of our co-founders, CEO Bob Mumgaard and Chief Science Officer Brandon Sorbom, are a rare breed: scientists who earned PhDs in plasma physics who also have deep business acumen. 1/3

It’s a great moment to celebrate milestones at CFS — in more ways than one. Today we announced we’re done manufacturing one of our key magnets and putting it through a rigorous, month-long battery of performance tests — which it passed. 1/4 #PowerMoves

On Monday, we announced a power purchase agreement with Eni, one of the largest energy companies in the world, in a deal worth more than $1 billion. But how can we sign an agreement like that without yet having demonstrated a machine that actually produces fusion energy? 1/2 #FusionEnergy

The fusion startup has inked a deal with Italian energy company Eni. The move is likely intended to set a price for fusion power.

Less than three months after announcing our partnership to sell Google power from our first ARC fusion power plant, we now have a second customer: Eni, an integrated energy company based in Italy with operations in 60 countries. 1/4 #PowerMoves

Yesterday in Chesterfield County, our ARC fusion power plant moved one step closer to the grid as the Chesterfield County Board of Supervisors unanimously approved a conditional use permit for the project. Our planned site is now zoned for fusion energy generation. #FusionEnergy #Virginia 🧵1/4

When our CEO Bob Mumgaard says you can see the Chinese fusion program from space, this is what he’s talking about. The country is investing heavily — $6.5 billion over the last two years — to try to win the race to commercialize fusion power: the last source of energy humanity will need. 1/4

To help fusion energy observers get a better handle on our industry’s progress our CEO, Bob Mumgaard, is detailing the six steps every fusion company must take on the path to delivering power competitively. Today, he digs into the second step: get your fusion fuel hot enough. #FusionEnergy

Why work on our ARC fusion power plant when we haven't switched on our SPARC demonstration machine? It's a fair question. Our answer: at CFS, we've deliberately charted a path to fusion energy that lets us work in parallel on multiple projects. 🧵1/3 #FusionEnergy blog.cfs.energy/how-863m-in-...
