Membrane-based AWE Device (MAWED)

In order to meet DARPA need, ChromoLogic LLC (CL) proposes developing a Membrane-based AWE Device (MAWED) to ensure a consistent supply of potable water as a distributable system. Unlike traditional cooling-condensing and absorption/desorption methods, MAWED uses an energy-efficient vapor capture and passive condensing approach, combined with a compact, high-surface-area design to meet DARPA requirements. When integrated, MAWED has a dimension size of 72×94×71 cm3 (L×W×H) with energy consumption of 74.6 Wh to generation 1 L potable water at 40 °F 30% RH. The energy consumption decreases with increasing temperature and humidity. Its straightforward design makes it a plug-and-play system, eliminating the need for complex sensors and control systems. Water is captured through diffusion and capillary effect, preventing contamination from the ambience and the capturing process. Additional water purification components eliminate potential biological contamination from long-term storage. Furthermore, the mineralization filter enhances the water's health by adding minerals. In Phase I, CL will fabricate a small prototype for the proof of concept. In Phase II, a high-fidelity full-size prototype will be prepared and demonstrated at DARPA facilities.
