The Fusion Conclusion is an independent publication by Dan Brunner on fusion as a technical field, an industrial sector, and a capital allocation problem. It is written for investors, suppliers, operators, and serious observers who want a clear, technically grounded view of what is real, what is overstated, and what matters next.
I publish three kinds of work:
- Fusion Fortnightly: separating the signal from the noise across the industry
- Technical-commercial deep dives: on companies, reactor concepts, and supply-chain bottlenecks
- Essays and market notes: on where fusion capital, engineering effort, and industrial demand are actually heading
About Dan
I co-founded Commonwealth Fusion Systems and served as CTO, where I led technology strategy, intellectual property, and the early conceptual design of SPARC. I hold a PhD in Applied Plasma Physics from MIT. Through Future Tech Partners, I advise investors and industrial companies on fusion and fusion-enabling technologies.
This publication is grounded in public information, first-principles reasoning, and my own analysis.

While I use today's AI tools to supercharge my research, copy-edit my writing, and debug my coding, I commit to publishing only my original ideas and writings, not AI slop. Any slop here is due to good old-fashioned human error.
