Zero fuel. Zero moving parts. Zero failure points. When primary water sources are compromised and resupply is hours or days out, the solar still converts saturated ground into clean, distilled water through nothing but sealed plastic and solar radiation — a redundancy that keeps operating long after filters clog and batteries die. Built in under thirty minutes from gear already on hand, it's the kind of low-tech resilience that separates mission-capable from mission-ended. Link in the first comment.
