Open Question: Will Helium-3 Yield Suffice?
Whether bred and lunar helium-3 can close a 400x per-unit supply gap in time is a genuine open question, not a solved one.
The question
A commercial unit needs about 400x today's domestic helium-3. The breeder produces a ~1.97 kg/yr helium-3 class per unit from a ~4 kg/yr tritium class; the tritium breeding ratio lever (1.1/1.5/1.8) shapes the rate. The open question is whether a breeder fleet, then lunar recovery, can scale fast enough to feed burner fleets.
What is uncertain
- How large a breeder fleet must be per burner it feeds
- How quickly breeders can be built and fuelled
- Whether lunar recovery matures on any relevant horizon
- Handling losses that erode usable yield
Honest posture
We present fleet-scale burner deployment as gated on this yield, not as assured. The breeder makes the fuel real; lunar helium-3 makes fleet scale conceivable; neither is a guarantee of rate.
The uncertainty here is compound: breeder build rate, fleet size per burner, handling losses, and the distant maturity of lunar recovery all multiply. Presenting fleet-scale burner deployment as gated on yield — rather than as assured — is the only claim the evidence supports. The breeder makes the fuel real; whether it can be made real fast enough is not yet settled.
