Recommends pursuing terrestrial production alternatives. - -## Agent Notes -**Why this matters:** This is the strongest peer-reviewed technical critique of He-3 extraction. It represents the disconfirmation target for the "He-3 as first viable lunar resource" hypothesis. The MVA is a credible institution (European Space Agency partner), not a fringe skeptic. - -**What surprised me:** The critique is specifically and solely about heat-based extraction methods. The entire argument assumes 800°C heating as the extraction mechanism. Interlune's non-thermal approach (10x less power) is not addressed because this analysis predates or ignores Interlune's specific IP. This makes the critique a partial miss rather than a complete refutation. - -**What I expected but didn't find:** Any engagement with non-thermal extraction chemistry. The paper treats heat-based methods as the only option, which is the key assumption that Interlune is challenging. - -**KB connections:** -- [[power is the binding constraint on all space operations because every capability from ISRU to manufacturing to life support is power-limited]] — this paper makes the power constraint quantitative for He-3 specifically -- falling launch costs paradoxically both enable and threaten in-space resource utilization — the mobility-centralization dilemma is a regolith logistics problem, not directly a launch cost problem - -**Extraction hints:** -- Claim: "Heat-based helium-3 extraction on the lunar surface faces a fundamental power-mobility dilemma that makes large-scale extraction impractical with current technology" (confidence: likely — based on solid physics) -- Counter-claim candidate: "Non-thermal helium-3 extraction approaches may resolve the power-mobility dilemma identified in heat-based systems, though Earth-prototype performance has not been validated in the lunar environment" - -## Curator Notes -PRIMARY CONNECTION: [[power is the binding constraint on all space operations because every capability from ISRU to manufacturing to life support is power-limited]] -WHY ARCHIVED: Provides the strongest counter-evidence to the "He-3 as viable first lunar resource" thesis; necessary for calibrating confidence on He-3 extraction claims -EXTRACTION HINT: The key scope distinction is heat-based vs. non-thermal extraction. A claim accurately characterizing this paper must specify that it applies to heat-based methods only.
