Industrial Fusion Demonstrator Roadmap

Fusion research is moving towards industrial demonstrators, but achieving net energy gain (Q>1) alone is not enough to deliver a viable power system. Future demonstrators must sustain a self-heating plasma (Q>5), breed sufficient tritium fuel (TBR>1.2), and enable modular manufacturing, assembly, and replacement of magnets for maintenance. Systems engineering choices made now will determine whether fusion can scale from experimental devices to industrial power plants.
