'Sweat Machine' Wrings Sweat Off Your Clothes, Turns It Into Drinking Water!
This is probably the first in its kind. The Sweat Machine, a creation of Swedish engineer Andreas Hammar, wrings sweat off your cloth, purifies it, and then offers the same to you as clean potable drinking water. The machine is based on a technology developed with The Royal Institute of Technology in Stockholm in Sweden. As you ruminate over this concept, Hammar goes a step ahead saying that the drinking water extracted off the cloth is cleaner that what you get in normal Swedish tap water.
How the machine works?
The sweat machine heats and spins the cloth extracting whatever liquid it can, and then a membrane filters the extract. The filter is THE most sophisticated part that defines the machine. Water vapour enters the material easily, where salts, bacteria and fibres from the clothes are trapped.
The machine was installed at the UNICEF-organized youth football tournament Gothia Cup in a bid to raise awareness about lack of clean water, and how it's making 780 million people across the world suffer. Fans watching the game could catch up the machine's action, as they quenched their thirst with each others sweat. Swedish soccer players Tobias Hysén and Mohammed Ali Khan, who'd earlier resolved to drink a glass of water extracted from their own sweat, got to have the first sip.
ISS has a similar technology where astronaut's sweat and urine are extracted and are converted to potable drinking water. Though the technology is pretty much the same, Sweat machine is a whole lot cheaper to develop in comparison to ISS's machine.
