 Interlune's full-scale lunar excavator prototype processes 100 metric tons of regolith per hour, but the press release emphasizes 'reduced power consumption' without providing specific kW requirements. This creates an observable gap between demonstrated hardware capability (excavation throughput) and the power infrastructure needed to operate it continuously. LunaGrid's 1kW demonstration scale is orders of magnitude below what continuous 100-tonne/hour excavation would require, making power the binding constraint on whether this hardware can actually operate as designed.

+Heat-based He-3 extraction quantifies the power constraint: requires seven-digit wattage (>1 MW) per mobile processing unit or 12 MW solar concentrator for centralized processing at 1,258 tonnes/hour throughput. The 2mg/tonne concentration and 40 million km² distribution area create a power-mobility coupling where neither distributed nor centralized architectures are viable with current technology.

 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.

+## Key Facts
+- He-3 concentration on lunar surface is approximately 2 mg per tonne of regolith
+- He-3 is predominantly found in particles smaller than 100 micrometers
+- Over 150 tonnes of regolith must be processed per gram of He-3 extracted
+- He-3 is distributed across approximately 40 million km² of lunar surface
+- Traditional thermal extraction requires heating to 800°C
+- A 12 MW solar concentrator can process 1,258 tonnes of regolith per hour using thermal methods
