HarmonoLogic, LLC — Department of Defense SBIR Phase I: To address Army need for a novel scalable energy-efficient technology to generate potable

Description

To address Army need for a novel scalable energy-efficient technology to generate potable water on demand from atmospheric humidity in hot arid environments, HarmonoLogic LLC proposes to develop a Nanocapillary Atmospheric Water Generation (Nano-AWG) system. This system is based on Bio-inspired extremely efficient nanocapillary water condensation and multifunctional TiO2 thin film for water accumulation, purification and collection. Utilizing this nanocapillary effect and switchable wettability of multifunctional nanostructured thin film, the proposed Nano-AWG system is highly energy-efficient (<200 WHPL at 70degrees F & 40% RH and<800 WHPL at 35degrees F & 43% RH with 2 grams of water per kilogram of air), light-weighted, compact, cost-effectiveness (<20 lb,<20 X 20 X 30 in., and<$200 for a Nano-AWG system with capacity of 2 gallon-per-hour), and capable of operating in all environments. It offers real-time water quantity and quality monitoring and control, fieldability, ruggedness, and turn-key operation, and environment-friendliness. In Phase I HarmonoLogic will demonstrate the feasibility of Nano-AWG technology by fabricating and testing a TRL-4 prototype. In Phase II we plan to refine the technology and fabricate an integrated TRL-5 Nano-AWG prototype.
