One company has designed a system, called Sweat Machine, to wring sweat out of clothes and turn it into potable water.

The Sweat Machine heats and spins clothes to extract the liquid from them, then filters the extract with a membrane developed with the Royal Institute of Technology in Stockholm. Yum.

The filter is the most sophisticated part of the machine. It’s “a bit like Goretex,” one of the machine’s designers, engineer and Swedish TV host Andreas Hammar, told the U.K.’s The Independent. Water vapor passes through the material easily, but it traps bacteria, salts and fibres from the clothes.

The demonstration is supposed to draw attention to the fact that 780 million people around the world don’t have access to clean drinking water. Contaminated water can be deadly, especially for children. UNICEF will be raising money for a more practical solution for those kids-water purification tablets.
