Cyborg system stifles your need to drink water
...Inserts that go in our noses convert moisture in the air we breathe into water, and other inserts at the ends of our renal and digestive systems keep water from leaving by those routes. A collar on our neck helps prevent perspiration by turning our body heat into electricity, so it doesn’t make us perspire, losing precious liquid.
Aside from the unpleasant joy of things stuffed in areas I care not to think of, my first thought is of Dune, desert planet of Arrakis, of the spice melange and the Fremen culture.
Perhaps the stillsuits were powered by body heat, though I thought it was from the pumping action during walking.
Anyways - I just thought this was yet another futurist idea that apparently is about to come to fruition.
