Self-Powered Piezoelectric Water Purification: An Open-Source Technology for Global Water Access

Two billion people lack access to safely managed drinking water. Waterborne diseases kill approximately 485,000 people annually, predominantly children under five. Every water purification technology that reliably works requires electricity, chemicals, or replaceable consumables. In the communities where waterborne disease is most lethal, none of these supply chains are reliable. This white paper describes a water purification technology that requires none of them. The Self-Powered Piezoelectric Water Purification System (Patent 44, CoreMason Technologies) installs as a cartridge inside a standard water pipe. Water flows through the cartridge. The flow vibrates piezoelectric elements inside. The elements convert that vibration into ultrasonic acoustic pulses. The pulses produce cavitation — microscopic bubble collapse events generating temperatures of 4,000-5,000 degrees Celsius and pressures exceeding 1,000 atmospheres at microscopic scale — destroying pathogens, degrading organic contaminants, preventing biofilm, and inhibiting mineral scaling. The water purifies itself by flowing. No electricity. No chemicals. No filters. No maintenance. Patent 44A extends this architecture to saltwater and brackish water desalination, addressing the accelerating crisis of saltwater intrusion into coastal freshwater aquifers. Both patents are released as CC0 — complete public domain. Any government, NGO, manufacturer, researcher, or community can use, build, deploy, and distribute this technology without permission, without royalty, and without restriction.
