The Compact-Fusion Landscape
A neutral map of the approaches in the field — high-field tokamaks, stellarators, FRCs, inertial and magneto-inertial — and where the Kronos design sits within it.
- High-field tokamak
- Compact, HTS magnets (Kronos's family)
- Stellarator
- Steady, disruption-free, complex
- FRC / MTF
- Compact, simpler, less mature
- Inertial
- Pulsed, laser-driven
Private and public fusion today spans several approaches, each a reasonable bet on a hard problem. A neutral map:
| Approach | Character |
|---|---|
| High-field tokamak | Compact, high-field HTS magnets — the fastest-growing family; Kronos's |
| Stellarator | Steady-state, disruption-free; complex 3D engineering |
| FRC / magneto-inertial | Compact and simpler; thinner experimental record |
| Inertial / laser | Pulsed pellet compression |
Within the high-field tokamak family, Kronos's specific position is distinctive: low-neutron D–³He fuel (most peers run D–T), direct energy conversion (most use a steam cycle), a negative-triangularity edge, and radical openness. The field benefits from multiple approaches being pursued in parallel; Kronos's is a particular, openly-documented bet. See the main approaches to fusion.
