STREED (Solar Thermal Resonant Energy Exchange Desalination)

Desalination & Distillation • Est. CapEx: $1,900 USD • Lifespan: 10 Years (Standardized)


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 Desalination & Distillation
Capital Cost (CapEx) $1,900 USD
Power / Energy Solar PV / Thermal
Target Scale Community Scale
Standard Lifespan 10 Years (Standardized)
Technology Maturity Prototype
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.
