Abstract

Marines must drink over a gallon of water a day to operate safely and effectively in hot climates. We propose to build field test prototype units to demonstrate innovative technology for a compact drinking water chiller. The chiller can boost water consumption by cooling an individual soldier s drinking water to low temperatures in the hottest environments. The unit will be portable, re-usable, requires no external source of electric power, and can meet the Navy s needs for cooling capability, compact size, and light weight. In Phase I, we proved the feasibility of our approach by: (1) evaluating alternative technologies and identifying an innovative cooling approach with the optimal combination of cooling capacity, cost, efficiency, reliability, component life, and weight; (2) demonstrating the basic cooling process in the laboratory; and (3) showing that the Phase II prototype can meet the Navy s specifications. In Phase II, we will build prototype coolers, demonstrate operation under realistic conditions, and deliver prototypes to the Navy for evaluation.
