Water, Land, and Resource Profile: Summary
A consolidated, honest view: the burner is water-light and land-light by architecture, the breeder is compact but cooling-dependent, and both carry stated gates.
This page consolidates the water, land, and resource story for both machines in one honest view. The pattern throughout is architectural advantages that are real, paired with gates that are stated plainly rather than softened.
Water
The burner (Aegis / MetroVolt) is water-light because direct energy conversion removes the steam-cycle condenser — the dominant water demand of a thermal plant — leaving only modest, closed-loop residual heat. The breeder (Hyperion) carries a real thermal load and its water use depends on cooling choice (wet versus dry). Neither claim is a published water number; both are architecture-level and design-and-simulation based.
Land
Both machines are compact, high-power-density plants whose footprint is buildings and setbacks, not a collection field. Co-location with load (Aegis on defense installations, MetroVolt at data centers) avoids transmission-corridor land. Brownfield reuse is feasible. The land case is comparative and mechanism-based, not a numeric superiority claim.
Resources and gates
- Fuel: deuterium unlimited, tritium bred, lithium abundant; helium-3 is ~400x gated.
- Materials: mostly common and recyclable; specialty supply chains (REBCO, beryllium, tungsten) are the resilience issue.
- Gates stated plainly: helium-3 supply, burner availability (~0.86-0.995 vs Tier III 0.99982), plug-coil and plug-regime physics gates.
- Timeline: breeder construction begins Q2 2027, FOAK first tritium ~2030; no hardware net-gain claim before FOAK.
The honest bottom line: the water and land advantages are genuine and architectural, the fuel and materials picture is strong except for the helium-3 gate, and the availability and physics gates are real bounds. Stating advantages and gates together is what makes the whole profile defensible.
