The Physics Is Now on the Record: CFS Publishes the ARC Basis as DOE Locks the National Fusion Roadmap
CFS published five peer-reviewed papers behind ARC’s 400 MW design, days before DOE finalized its fusion roadmap. What’s proven — and what isn’t.
Fusion’s May 2026 Inflection: SPARC at 75%, Polaris in Tritium, and Why Q>1 Is Now a Construction Problem
Two private fusion machines crossed milestones this quarter that ITER won’t reach until 2039. Q>1 is no longer a physics question — it’s a schedule question.
Helion’s 150 Million Degree Bet: Why Field-Reversed Configuration Could Skip the Steam Cycle Entirely
Field-reversed configuration could skip the steam cycle entirely. Inside Helion Polaris and direct energy conversion.
SPARC Just Hit 75% Complete. Now the Hyperscalers Are Watching.
Commonwealth Fusion Systems lowered the second half of the SPARC vacuum vessel in May 2026. The path to Q greater than 1 is now a hardware question.

Helion’s Polaris Just Hit 150 Million Degrees. The Whole Fusion Industry Is Now Watching One Building in Malaga.
Polaris reached 150 million °C and the first private D-T fusion. Now Orion is breaking ground in Malaga, and Microsoft’s 2028 PPA is on the clock.
The Race to Power AI: Why Helion’s Direct Energy Conversion Is the Fastest Path to Fusion Electricity
AI data centers will consume 1,100 TWh in 2026 — Japan’s entire output. Helion Energy’s field-reversed configuration with direct magnetic energy conversion eliminates the thermal cycle entirely. No steam. No turbine. 150M°C D-T fusion demonstrated Feb 2026. 50 MW Orion plant building now. Grid power by 2028.
