Orbital Systems, a ‘clean-tech’ startup out of Sweden, has raised $15 million in Series B funding. The company’s founder and CEO Mehrdad Mahdjoubi has developed new re-purification technology, in collaboration with NASA, that significantly reduces the amount of water and energy used when taking a shower. The same technology can also be used to save water in other domestic situations.

The clever bit, however, is the filter tech that ensures bacteria and other ‘bad’ elements found in water coming off your body is removed in each cycle and that if the water is deemed too contaminated, it’s discarded altogether. The result is that the company claims OAS consumes only 5 litres of water compared to up to 150 for a 15 minute shower.
