There are numerous commercial and military applications for the proposed technology. Commercial applications include untethered personal cooling systems for law enforcement, nuclear/chemical plant workers, and heat-sensitive multiple sclerosis patients. Military applications include personal cooling systems for soldiers or marines wearing chem/bio protective gear, body armor, EOD suits, or level-A HAZMAT suits. The proposed system can be used in any future space suit, with applications that include lunar and Mars exploration or constructing/servicing next-generation space telescopes while maintaining a clean environment. The basic technology can also be used to provide rugged, nonventing thermal and humidity control for spacecraft, manned rovers, and habitats.
