In space, astronauts go for years without a fresh supply of water. Floating in a capsule in outer space they wash and drink from the same continuously recycled source. So why, asked Swedish industrial designer Mehrdad Mahdjoubi, do we not do the same on Earth?
This was the concept behind the OrbSys Shower -- a high-tech purification system that recycles water while you wash. In the eyes of Mahdjoubi, we should start doing it now, before it becomes a necessity.
