Would you like a glass of ice cold sweat? Of course you would! Well, just get yourself a special sweaty water machine. All you have to do is fill it with perspiration soaked clothes and the machine will turn all that lovely bodily dampness into water. DELICIOUS!
Actually, the machine is being used in Sweden as part of a Unicef campaign to raise awareness about the lack of clean water in developing countries. So far 1,000 people in Gothenburg have so far ‘taken the dare’ to drink a glass of sweat, and seemed quite happy about it, too.
Engineer Andreas Hammar created the machine using a water purification system invented by a Swedish company called HVR. He said: ‘We use a substance that’s a bit like Goretex that only lets steam through but keeps bacteria, salts, clothing fibres and other substances out.’
He continued: ‘The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml [0.3oz], roughly a mouthful.’
The only problem is that you need a lot of sweat to produce any water. And unless you follow Eric Pickles around the Sahara with a bucket all day, you’re not going to help the 780,000 million people in the world without access to clean water.
But Hammar says it’s cleaner than the local tap water - and when you think that the stuff that comes out of the tap has been filtered through millions of bowels and bladders, a bit of sweat water is actually a tasty artisan treat.
