The shower works as a "closed loop system," the article reported, where water that goes down the drain is instantly purified to drinking water standards and then pumped back through the showerhead.

"With my shower, which is constantly recycling water, you'd only use about five liters of water for a 10 minute shower ... In a regular shower you would use 150 liters of water — 30 times as much. It's a lot of savings," said Mahdjoubi.

According to the article, the process is so quick that the water only needs to be reheated slightly.

"In an extreme environment such as a space mission to Mars, design concepts are brought forward to use all of the possible resources to make it there and back. I don't see any reason why we can't be as efficient on Earth as we can be in space," said Mahdjoubi.
