The Fusion Conclusion is an independent publication launched in November 2025 by Dan Brunner. It aims to bring fusion insider insights to the "fusion-curious" outsiders wanting to learn more about the developing fusion energy industry.

I aim to publish regular posts:

  1. Fortnightly update on the latest happenings in the fusion industry.
  2. Essays on broad topics on the growing fusion industry.
  3. In-depth looks into fusion technical areas, often tied to recent essays.

About Dan

I was the co-founding Chief Technology Officer of Commonwealth Fusion Systems where I managed the company's technology roadmap and intellectual property. I built and led the early team doing the conceptual design of SPARC fusion demonstration device as well as other smaller projects.

I earned my PhD in Applied Plasma Physics (the fundamental physics of fusion devices) from MIT and worked there as a research scientist before founding Commonwealth Fusion Systems.

Presently, through Future Tech Partners, I advise investors, startups, and industry on new technologies with a strong focus on fusion energy.

AI policy

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.
