Before you scream ‘absurd’, let me tell you that I am talking about Puri – a sea water desalinating bottle. There are several ways to remove saline from sea water, for example evaporation, vapor-pressure, and ion-exchange membrane method but all of them are not practical for use on a life raft or rescue boat and require big equipments. The Puri on the other hand is a slim portable bottle that works with a pumping action. Take a look at its video below.
Puri is a 2013 IDEA Design Awards entry.
