How do astronauts take a shower?
While working at NASA, one of the things Mehrdad Mahdjoubi focused on is how astronauts had to conserve water – not only for drinking, but also for hygiene. When he moved back home to Malmö, he created a shower that uses 90% less water than a conventional one by instantly purifying and recirculating it to the showerhead. A typical 10-minute shower uses 100 litres of water, which Mehrdad’s system reduces to only 5 to 10 litres, while also making an 80% energy saving. In 2018, his company Orbital Systems got an EIB loan to scale up production and R&D.
