I’ve been watching China ramp up its fusion energy efforts for years. Now the country is taking it to the next level by providing capital of $2.1 billion for the new China Fusion Energy Co., a subsidiary of the state-owned China National Nuclear Corporation. This is now a direct,

.RealtaFusion offers a deep look here into the tradeoffs of the mirror fusion concept. This is a good example of how to push the field forward. It has what you'd want. The authors: • Use state of the art tools • Show what changed from prior studies • State assumptions

Last year, I published an open letter describing the six steps that companies have to take to bring a competitive fusion power plant to the grid. The idea is to give a framework to investors, press, analysts, science enthusiasts, and others watching the growing fusion energy

Today we announced our Series B2 investment round — $863 million from a broad group of investors from around the world. This funding, which is the largest chunk of committed capital for a deep-tech company since our Series B in 2021, will take Commonwealth Fusion Systems to the next level. We’ll

Why work on our ARC fusion power plant when we haven't yet switched on our SPARC demonstration machine? It's a fair question. And here's our answer: at CFS, we've deliberately charted a path to fusion energy that lets us work in parallel on multiple projects. Our new $863

To help fusion energy observers get a better handle on our industry’s progress, I’m detailing the six steps every fusion company must take on the path to delivering power competitively. Today, I’m digging into the second step: get your fusion fuel hot enough. For fuel, fusion

I read through Zap Energy’s new paper about Century. It’s great to see more people tackling the integration challenges of a fusion machine, especially one as novel as the z-pinch. This was nicely executed — you can clearly see how if the plasma physics works out as hoped there

Big update: Half of our vacuum vessel, the very heart of our SPARC fusion machine, has landed in Devens, Massachusetts. The vacuum vessel is the donut-shaped chamber inside SPARC that'll house our fusion fuel — a superhot cloud of charged particles called a plasma. The delivery
