Futuristic Unmanned Submarines Could Move Like Stingrays — mashable.com

The next step in nature-inspired engineering could come in the form of small, stingray-like unmanned submarines. Researchers at Harvard University and the University of Buffalo have studied how the sea creatures swim and believe their movements could be built into future underwater vehicles to make them more efficient. The research may be especially applicable to small, driverless submarines that could perform water clean-up or rescue missions, Iman Borazjani, an engineering professor at the University of Buffalo, told Mashable.
