Artificial Blubber Keeps Divers Warmer Longer

Artificial Blubber Keeps Divers Warmer Longer
An innovative new gas infusing process adds artificial blubber to let wetsuits keep wearers warmer longer.

Developed by the team at MIT, the process builds on the common technique of infusing wetsuits with tiny pockets of nitrogen gas to add insulation. To increase the suit’s insulation properties, the team experimented with adding either xenon or krypton gas to the suits, which both have a lower thermal conductivity than nitrogen. The gas was infused by placing a standard wetsuit in an autoclave for one day, and resulted in an insulating layer able to allow the wearer to survive in water as low as 50°F for up to twenty hours.
