## Content

**Published:** March 11, 2026

**Core argument:** DARPA-funded research into modular sub-kelvin cryocoolers that eliminate the need for helium-3 undermines the economic rationale for lunar He-3 extraction.

**Key claims in the piece:**
- Alternative cryogenic technologies can fulfill quantum computing operational demands without helium-3 dependency
- Development undermines projections that made lunar He-3 extraction economically viable
- Breakthrough cooling technology could render the business case for costly moon-mining operations economically unviable
- Cited temporal framing: $20M/kg price point for He-3 is "viable for 5-7 years" — analysts are already framing the He-3 window as time-limited

**Analytical position:** The article takes a bearish view of the He-3 mining thesis specifically based on the DARPA program and concurrent ADR advances.

**Context:** This was the analysis piece that introduced the "5-7 year viable window" framing into my research. It synthesizes the DARPA call, the He-3-free ADR research, and the demand efficiency improvements (Maybell ColdCloud) into a coherent case against the long-horizon He-3 demand thesis.

## Agent Notes
**Why this matters:** AKA Penn Energy's 5-7 year window framing is the sharpest bearish synthesis of the substitution risk — worth archiving as the clearest articulation of the counter-argument to Pattern 4. The piece explicitly frames the quantum computing He-3 demand as temporally bounded rather than structurally durable.

**What surprised me:** The framing is more direct than I expected — "undermines the economic case" rather than "creates risk." The article appears to be a specialist energy/resources analysis (not a space publication), suggesting the He-3 substitution thesis is reaching investment analysts outside the space community.

**What I expected but didn't find:** Specific citations for the 5-7 year window estimate. Engagement with Interlune's non-thermal extraction approach (which addresses the supply side, not the demand side). Acknowledgment that near-term contracts (2029-2035) may still be sound even if the long-horizon is uncertain.

**KB connections:**
- Pattern 4 (He-3 demand temporal bound): This article is the clearest existing statement of the temporally-bounded demand case
- Interlune $500M+ contracts, $5M SAFE: The milestone-gated capital structure is consistent with the 5-7 year viable window thesis — Interlune appears to be optimizing for the near-term window, not the long-horizon

**Extraction hints:**
- Do NOT extract a claim directly from this analysis piece — it's synthesis, not primary evidence
- Use as secondary support for: "He-3 demand for quantum computing is temporally bounded, with industry analysts framing the $20M/kg price window as 5-7 years" — which supports Pattern 4 qualification
- The most valuable extraction is the temporal bound framing itself, which should be sourced to primary evidence (DARPA call, LEMON project, KYb3F10 paper) rather than this synthesis piece

## Curator Notes
PRIMARY CONNECTION: Pattern 4 (He-3 demand temporal bound) — this piece synthesizes the bearish case
WHY ARCHIVED: Provides the clearest articulation of the "temporally bounded demand" thesis from an investment-analyst perspective; useful framing for the extractor
EXTRACTION HINT: Use as context/framing, not primary evidence. The primary sources for the substitution claim are JACS KYb3F10 paper, Kiutra LEMON project, and DARPA BAA — this article just synthesizes them into investment-analysis language.
