Swedish startup Orbital Systems originally collaborated with NASA to develop the technology for their shower system, called OAS, which the company claims reduces water waste from showers by 90%. With a built-in purification system, OAS reuses the same batch of water, using only two gallons per shower – versus 20 gallons used in a typical shower. The company plans to take this technology developed for space and put it in people’s homes, which will not only save water, but save families a lot of money, the company says.
