A total number of around 780 million people of two Americas (North & South) and Russia don’t have access to clean drinking water. And therefore lately UNICEF has built a machine called Sweat Machine that can turn sweat in T-shirt into drinking water!
The Sweat Machine has been created by Swedish engineer and TV personality Andreas Hammar upon the request of UNICEF. So, how does the machine work? Well, the machine spins and heats the sweaty T-shirt when kept in the machine in order to remove the sweat. The vaporized sweat then passes through a special membrane called ‘Membrane Distillation’ which only let water molecules get through it and at the end water comes comes out from the machine. Hammar has mentioned that one sweaty T-shirt normally provides around 10 ml (0.4 fl oz) of water – or only one mouthful.
Since the launch of this machine, more than 1,000 people have “drunk other’s sweat” in Gothenburg. But the very interesting thing is Swedish people apparently don’t sweat very much.
