 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.

+Moon Village Association analysis quantifies the power constraint for He-3 extraction specifically: traditional thermal methods require 12 MW solar concentrators for industrial-scale processing (1,258 tonnes/hour) or seven-digit wattage for mobile rovers. With He-3 at ~2 mg/tonne requiring >150 tonnes of regolith per gram, the power requirement creates a mobility-centralization dilemma where neither distributed nor centralized processing is 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.

+- He-3 predominantly found in particles <100 μm
+- Over 150 tonnes of regolith required per gram of He-3
+- He-3 distributed across ~40 million km² of lunar surface
+- Traditional heat-based extraction requires 800°C heating
+- 12 MW solar concentrator needed for 1,258 tonnes/hour processing rate
