Unsinkable Metal Tubes Could Lead to Resilient Ships, Floating Platforms and Renewable Energy Innovations

Aluminum tubes etched to be superhydrophobic trap air to remain afloat despite damage, enabling new resilient floating platforms and renewable wave energy applications, researchers said.

Summary by TechXplore
More than a century after the Titanic sank, engineers still have hopes of someday creating "unsinkable" ships. In a step toward reaching that lofty goal, researchers at the University of Rochester's Institute of Optics have developed a new process that turns ordinary metal tubes unsinkable—meaning they will stay afloat no matter how long they are forced into water or how heavily they are damaged.
