Some desert animals, like the kangaroo rat, get through their lives without needing to drink even a drop of water. Now, a Japanese design company aims to make humans just as efficient. Faced with a fictional, future scenario of global apocalypse, Takram was tasked with the challenge of creating a water bottle for the end-times. The designers quickly realized that the best approach was not a bottle at all, but a set of artificial organs that retain and recycle the water already present in the body. Their Hydrolemic System is the cyborg's answer to surviving global warming, nuclear explosions and Death Valley.
Humans are leaky. We sweat, pee, and breathe out all our hard-earned water. The Hydrolemic System uses several devices to minimize this loss. Two nasal inserts harvest exhaled moisture. A generator implanted in the jugular, in combination with a neck collar, transforms body heat into electricity and reduces the need for sweating. Even better are the urine concentrator and the rectal fecal dehydrator, both intended to make every bathroom trip a dry-as-dust affair. The system works in concert with "rubedo candies", small pills that contain a day's nutrients and 32 mL of water – less than a thimble-full.
