Okay, maybe that isn't exactly news. But the fact that designers and engineers in France have developed a shower that recreates that natural filtration process is.
The shower has a mini-eco system underneath it. As the waste water goes down the drain it passes through a series of natural filters, including reeds, rushes and sand. Eventually returning to a catch.
While the design is not in production yet, the inventors hope to see it become something concrete soon. They have been inundated with quires since they put the design up on the internet. They hope that their design not only helps people think about recycling water, but also how they use water.
