Independence Duration and Fuel Interval
How long a base can run with no external supply is set largely by its on-site fuel interval, a key resilience metric for the burner.
A defining resilience metric
Independence duration is how long an installation can sustain mission power with no external input — no grid, no resupply. For a fuel-fed base it is short, set by fuel storage and consumption. For a burner it is potentially long, set by the energy density of its helium-3 charge and its steady operation.
Why the burner extends it
- D–3He is energy-dense: a small fuel mass carries a large amount of energy.
- Steady base-load operation means predictable, efficient fuel use.
- A compact charge is easier to stockpile on-site than bulk liquid fuel.
The honest boundary
Independence duration is bounded by two things beyond fuel: availability and non-fuel dependencies. A long fuel interval does not help if the unit is down (availability 0.86–0.995), so redundancy still matters. And the fuel charge must be filled from a sovereign supply that, at ~400× demand, does not yet exist at scale — so independence duration is a design property waiting on the fuel pathway.
Independence duration is one of the burner's most attractive resilience properties: a base that runs for a long interval on a compact, stockpilable charge is far less hostage to its supply lines. Stated honestly, it is a genuine advantage conditioned on availability and on a sovereign fuel supply being real.
A genuine advantage, honestly bounded
A base that runs a long interval on a compact, stockpilable charge is far less hostage to its supply lines — one of the burner's most attractive properties. It is bounded by availability, since a long fuel interval does not help while a unit is down, and by the sovereign supply that must fill the charge. Independence duration is a real advantage conditioned on the availability and fuel gates.
