A Swedish engineer has built a new machine for Unicef that can convert a person’s sweat into clean drinking water.

Hammer revealed that the machine extracted moisture from worn clothes and sent it through a series of filters that purified the water and provides a water supply that is cleaner than the local tap water. More than 1,000 people so far have drunk water cleaned by the machine.
“We use a substance that’s a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibres and other substances out. They have something similar on the [International] Space Station to treat astronaut’s urine – but our machine was cheaper to build. The amount of water it produces depends on how sweaty the person is – but one person’s T-shirt typically produces 10ml [0.3oz], roughly a mouthful”, Hammer said.
