Sweat Machine – Turns Sweat Into Drinking Water

While drinking water that has been made out of other people’s sweat may sound rather unappealing, the reason behind this new machine (built by a group of tech-savvy, environmentalist Swedes) is to highlight the very real problem of water shortage in many parts of the world.

An issue that is only going to get worse as population growth continues.

Aptly named the “Sweat Machine” the technology employed to make it work comes straight out of NASA. The machine works by extracting the perspiration, which is 99% water, out of people’s clothes.

Dirty clothes are tossed into a dryer, where they are spun and squeezed for every last drop of liquid.

The liquid is then heated, exposed to ultra-violet light and then passed through a series of high-tech filters to remove the salt, bacteria and any other undesirable particles.

The Sweat Machine was unveiled as part of a UNICEF campaign promoting safe drinking water.

The final stage of the purification process, involves a simple coffee filter. This retains any textile fibres left over from the clothes. The result is perfectly drinkable distilled water.

Although the Sweat Machine is unlikely to be of any practical use in the fight against water shortage, the technology does help draw attention to the kinds of innovation that will be required to feed the World’s thirst in decades to come.
