Machine Extracts Sweat From Clothes & Turns It Into Drinkable Water
How do you like the idea of extracting the sweat from your clothes and turning the moisture into drinkable water? Well, more than 1000 people have already drunk other people's sweat in Gothenburg. The machine is already in use in Sweden - and it just works like washing machine. The sweaty clothes get spinned and heated so that the sweat is removed. The vapour is then passed through a special membrane that only lets the water molecules pass through, which is then condensed to water. The project has been designed as a part of campaign by Unicef in Sweden to highlight the fact that 780 million people in the world do not have access to clean water.
The creator of the machine, Er. Andreas Hammar says that the output of this machine is cleaner than the local tap water (obviously). Hammar is known in Sweden for his TV appearances. The critical part of the sweat machine is the water purification component developed by a company called HVR in association with Royal Institute Of Technology. The technique used to separate water from salt is called 'membrane distillation'.
Hammar said that he used a substance similar to Goretex that only lets the steam pass through leaving behind bacteria, clothing fibers and other unwanted substances. He points out that the astronauts on the ISS (International Space Station) have something similar which converts Urine into drinkable water. He adds that his machine was a lot cheaper to build.
The amount of drinkable water produced by the system is directly proportional to how sweaty the person is. However, a normal person would produce about 10 ml. The machine is on display at the Gothia Cup - World's largest international youth football tournament. The organizers were bit disappointed because people didn't sweat to their expectations, because of the weather. To fix that problem, the organizers have installed exercise bikes alongside the machine. Those who want to try drinking water from their own sweat have to exercise like there's no tomorrow, develop thirst and get water from their own sweat.
We've setup a poll at the bottom of this article to know how many of you would love to try drinking water made from their own sweat.
