Safe drinking water can be made from sweat

[1]

A machine that takes sweat from your gym clothes and turns it into drinkable water has been developed in Sweden.
The Sweat Machine built by engineer Andreas Hammar, has a filter, developed at the Royal Institute of Technology in Stockholm, as the highest technology component.
The rest is off-the-shelf parts, including a clothes dryer. To get the water out of the sweat — which is 99 per cent water itself — they put the sweaty clothes in the dryer component.
That spins and squeezes out the sweat, Discovery News reported. The sweat gets heated, exposed to UV light and pushed through the high-tech filters, to get rid of salts and bacteria.
