Synthetic 'blubber' could triple divers' survival time in icy water
Even the hardiest diver can't last longer than an hour in cold water using a modern wetsuit, and that's no good if you're a special ops soldier or otherwise need to stay under the sea for hours at a time. MIT has a simple solution: imitate the blubber that keeps seals and polar bears safe. They've developed an "artificial blubber" that promises to extend swim times in chilly water (under 50F) to as long as three hours. The approach combines a newly processed material with pockets that keep the cold out.
