Now, machine that turns sweat into safe-to-drink water

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. The water then goes through a coffee filter to get the fibres from the clothes out and the result is distilled water.

Some 500 people have successfully tried out the machine, the report said.
Stefan Ronge, chief creative officer at Deportivo, an advertising agency which backed the project in conjunction with UNICEF, said the idea is to highlight the scarcity of fresh water in some regions of the world.
The machine will be shown off this week at the Gotha Cup, a youth soccer tournament in Sweden. Players will bring in their sweaty clothes and get a cup of water back.
