A Machine That Turns Sweat into Drinking Water.........

I came across this story today about a new invention that claims to be able to turn sweat into drinking water...

Those hot and sticky summer nights might have a new purpose - providing your next cool glass of H2O...

The machine was built for the United Nation's charity Unicef by engineer and TV personality Andreas Hammar, in Sweden, to promote the campaign to increase access to clean water.



More than 780 million people have no reliable clean water supply, according to Unicef, leading to thousands of daily deaths from contagion and basic thirst.

The sweat distillation machine is not intended as a solution to the issue, but a PR-tastic way to highlight the choices people in the developing world have to make.

The Sweat Machine takes moisture from worn clothes, purifies the water with a series of filters, and turns it into water that the makers insist is cleaner than the local tap water.

It then dares passers-by to drink the water - which apparently more than 1,000 people have so far done.

There are many different techniques to extract and purify water. The technical challenge was to build the sweat machine like in the space travel industry, where every filthy water drop whether it's cooling water, urine or just sweat, is invaluable. It is hard to believe, but the water extracted from the machine is actually cleaner than ordinary swedish tap water.

So what do you all think, would you give it a go?

iv'e always wondered why they haven't made one that cleans sea water,which also doubles to get the salt to

Hells yeah! That's one tiny step along the road to a functional stillsuit.

Just need to miniaturize the equipment, work on collection and filtering process to handle other fluids, and create a vascular suit with pumps in the heels.

Oh, Science. You'll get us there. I believe in you.

actually cleaner than ordinary swedish tap water.

Ok, I'll bite...why did they choose "Swedish" tap water for the comparison.....???

Residents of Ostersund, Sweden, were told their tap water is drinkable after three months of boiling water supplies after a parasite outbreak, officials said.

Oh, that's why!

Talk about a Rube Goldberg contraption.

Nice that it was made to bring awareness and such. But impractical in the output volume side.

Water is a possible replacement for petrodollars. Simple as that.

Actually, desalinization is used in many parts of the world, especially the Middle East. When I was in Saudi, you could use the municipal water from the process for cooking and cleaning, but not straight drinking though. May have changed now, as that was quite some years ago.

They usually run the desalinated water through a reverse osmosis system for drinking.
It's good.
Then they chlorinate it for storage.
Bleh.
