The John P. Stevens High School InvenTeam will invent a life jacket for prolonged search and rescue. It is designed to increase chances of survival for individuals in dangerous aquatic situations for a prolonged but undetermined amount of time. It will provide not only basic flotation and heat insulation but also hydration via manually operated desalinating system that renders seawater potable and the user’s location via emergency position-indicating rescue beacon that alerts rescuers, dramatically increasing chances of survival and rescue. It will cost approximately $1,400 for the prototype and approximately $800 when taken to mass production. It has the potential to be offered alone and as a staple of emergency packs available in various vehicles such as planes and ships as a method of immediate response to aquatic emergencies and disaster.
