The Long Horizon

This is a hundred-year project stated honestly: near-term steps that are concrete, a far endgame that is aspirational, and no pretense that they are the same thing.

Vision, not specification. This page describes a future that fusion could help make possible — not a product promise, forecast, or performance claim. The Kronos machines today are design and simulation studies: the breeder (Hyperion) and the burner (Aegis / MetroVolt). No hardware net-gain has been demonstrated; construction of the first breeder is planned to begin in Q2 2027, with first-of-a-kind first tritium targeted around 2030.

Different claims for different distances

One reason visions lose credibility is that they collapse near and far into a single breathless promise. Kronos keeps them separate. The near term is a set of engineering milestones with dates and conditions. The far term is a picture of the world those milestones aim at. The first is a plan; the second is a direction.

Near term, the concrete facts are these: the machines are design and simulation studies today; construction of the first breeder is planned to begin in Q2 2027; first-of-a-kind first tritium is targeted around 2030; and no hardware net-gain is claimed before that. Everything beyond — fleets, abundance, a healed planet — is explicitly the long horizon.

Why the far term still belongs on the page

If only the milestones are stated, the work looks like an end in itself. The endgame explains why the milestones are worth the effort. Holding both — rigor about the next step, clarity about the destination — is how an ambitious project stays honest. The far term earns its place precisely because it is labeled as far.

The discipline

• Near-term claims carry dates and conditions and can be checked.
• Far-term claims are labeled vision and make no performance promise.
• No economics appear at either horizon.
