MASSACHUSETTS, June 21, 2017 - A company called Open Water Power (OWP) has developed a water-powered battery to improve performance of unpiloted underwater vehicles. OWP’s aluminum water power system is said to be safer than lithium-ion batteries and allow the sub-surface drones 10 times more range. The U.S. Navy is working with OWP to replace batteries in acoustic sensors designed to detect enemy submarines. “Our power system can drink sea water and discard waste products,” said OWP Chief Science Officer Ian Salmon McKay. “But that exhaust is not harmful, compared to exhaust of terrestrial engines.” OWP was recently acquired by L3 Technologies.
