STREED (Solar Thermal Resonant Energy Exchange Desalination)

Membranes & Advanced FiltrationEst. CapEx: Low-cost / Locally fabricated


Technical Overview

A filter-free and battery-free solar desalination prototype from Rice University that converts saltwater to potable water around the clock. Built with durable, low-maintenance materials, it targets remote communities lacking reliable power infrastructure.


Key Specifications & Engineering Parameters

Parameter Specification
Category Membranes & Advanced Filtration
Capital Cost Low-cost / Locally fabricated
Primary Mechanism Sunlight heats a saltwater chamber to produce vapor, which is channeled into a separate condenser. A resonant energy exchange mechanism stores and transfers thermal energy rhythmically, allowing the system to maintain production overnight without filters, membranes, or external electricity.
Target Scale Household / Village Cluster
Standard Lifespan 10 - 20 Years
