The future of fusion isn't built all at once. As #SPARC moves closer to operation, our team is commissioning the systems that make fusion possible — 1/4

What's different now about commercializing fusion energy compared to past efforts? Three things, CFS CEO and Co-founder Bob Mumgaard told Adele Peters of @fastcompany.com. 1/5

Our first three achievements as part of the @departmentofenergy.bsky.social (DOE)’s Milestone-Based Fusion Development Program centered on our SPARC fusion demonstration machine. Now we’ve attained the next two DOE milestones — this time recognizing SPARC’s successor, ARC. 1/6 #FusionEnergy #Energy

If you want to literally build the future, we're holding a hiring day on Saturday, August 15 for production technicians who can help our work in fusion energy innovation. It’ll be at CFS headquarters in Devens, Massachusetts. 1/3

Today, CFS announced another major advance in our fusion energy push: we raised an additional $1 billion in funding. This is the largest investment round in commercial fusion worldwide since our $1.8 billion funding round in 2021, bringing our total capital raised to $4 billion. 1/4 #FusionEnergy

In the last year, investors brought $4.5 billion of new funding to fusion companies, dwarfing governmental fusion budgets, according to the newest @fusionindustry.bsky.social yearly report on the industry. 1/4

It's been a busy six months at Commonwealth Fusion Systems (CFS). In the newest of our twice-yearly video updates, CEO Bob Mumgaard discusses how dry dress rehearsal is occurring in parallel with #SPARC assembly, and shares other recent progress: 1/3

In its 250 years, America has created some of the most influential innovations in human history. Now, almost 60 years after putting a man on the moon, we’re on the cusp of bringing a star to Earth. 1/2 #America250 #IndependenceDay #AmericanInnovation

It’s time for another Reddit Ask Me Anything (AMA) — only this time it’s more of an Ask Us Anything. From 9:30–11:30 a.m. ET on June 30, four of our physicists will answer your questions on our five new peer-reviewed papers about the physics basis of our ARC fusion power plant. 1/5 #FusionEnergy

“Support from the government would be essential … otherwise we fall into the trap we’ve fallen into many times before, where the U.S. seeds innovation with an 's' and then cedes it with a 'c'.” 1/3

Today, we laid the physics foundation for our ARC fusion power plant. ⚛️ With 5 deeply researched papers — validated by independent peer review and published in the Journal of Plasma Physics from @universitypress.cambridge.org — we’ve shown we've nailed the science of producing fusion power. 1/7

Today we announced a new strategic agreement with the Singapore-based @astarsg.bsky.social. This 5-year collaboration is designed to develop technologies for commercial fusion power plants. 1/7 #FusionEnergy

“Over and over we meet long-term milestones, like securing our supply of high-temperature superconducting (HTS) tape, delivering our first prototype magnet, building a factory, and taking delivery of long-lead equipment,” said CFS Chief Commercial Officer Rick Needham... 1/4

Today we announced a new major step in our commercialization effort: We’ve applied to plug our first ARC fusion power plant into the grid. This crucial move shows that CFS is successfully navigating the complexities of delivering power, not just generating it. 1/5 #PowerMoves

“Fusion uses tritium, but it also makes it as it goes. It’s sort of like a sourdough starter. You use it and then regenerate it— that’s been shown to work in various labs. So to do it, you need a little bit of starter. Right now, that starter comes mostly from fission power plants.” 1/5

The Boundary Collaborators Workshop lets us and collaborating researchers tackle these challenges. That’s important work as we prepare to operate SPARC and explore new boundary physics options for ARC. 6/6

But clever physics techniques let us lower that heat to bearable levels. In practice, how well we manage heat at the plasma’s edge strongly influences how well the fusion process works in the plasma core. 5/6 #FusionEnergy #physics

SPARC & ARC will produce energy by combining the particles in superhot fusion fuel called a plasma. The plasma core is the hottest part, at >150 million degrees Celsius. But the temperature will drop toward the edge of the plasma, a region that’s the focus of a specialty called boundary physics. 3/6

We just wrapped up our second Boundary Collaborators Workshop — a conference that lets Commonwealth Fusion Systems (CFS) experts meet with peers from universities, national labs, and companies whom we invite over to dig into the physics of our fusion machines. 🧵 1/6 #FusionEnergy #physics 🔌💡

4/4 As CFS CEO and Co-founder Bob Mumgaard puts it:

Humanity will ultimately benefit from a commercial fusion market in which companies tackle different approaches to fusion technology in parallel. That's why this partnership between CFS and Realta Fusion matters. 🧵 1/4 #FusionEnergy

CFS announced today we’ll design and build high-temperature superconducting (HTS) magnets for Realta Fusion in a long-term strategic partnership that’ll benefit both companies’ efforts to bring this new form of clean, affordable energy to the electricity grid. 1/4 #PowerMoves

3/5 That’s because we need to do a heap of prep work for each one, on top of the fact we'll need to thread each through a set of nine D-shaped toroidal field (TF) magnets before we can weld the two assemblies together. #Energy

With both halves of the SPARC vacuum vessel now inside Tokamak Hall, the donut shape of our tokamak is starting to make more visual sense. 1/5 #FusionEnergy

3/6 As part of CERAWeek, CFS CEO and Co-founder Bob Mumgaard sat down with Lucia Tian and Marc Spieler, two of our close working partners at Google and NVIDIA, to discuss how we're thinking about scaling fusion energy and how our technology and AI benefit from each others' advancements.

...And then there were two. Our D-shaped toroidal field (TF) magnets are the first of SPARC's three magnet types that we're installing, which is why our team is heads-down finishing and shipping these out of our magnet factory. 1/4 #SPARC
