Zero-Electricity Water-Hammer Desalination

Zero-Electricity Water-Hammer Desalination is a concept white paper proposing the use of controlled water-hammer pressure, generated from wave and tidal flows, to directly drive reverse osmosis without electricity as the main energy intermediary. The document outlines a shore-based system design, the complementary use of tidal baseload, and a multi-layer resilience approach (storage + accumulator + tide + optional low-grade thermal backup). It acknowledges earlier related work on hydraulic-ram desalination and presents this contribution as a system-level framing rather than a claim of first invention. All technical estimates are theoretical. The paper is intended as a public priority disclosure and an invitation to experimental collaboration. No experimental validation is claimed.
