Unsinkable metal tubes could lead to resilient ships, floating platforms and renewable energy innovations

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.
