The survival time even when wearing the best of wetsuits is extremely limited when the Navy Seals carry out their dives in the Arctic Waters or when people or rescue teams need to dive in lakes and ponds which are covered in ice. More over the experience can be extremely painful as the pain is excruciating. It is therefore very important to find out ways and means to extend the survival time underneath the water without having any negative impact on the mobility. The US Navy and science divers have been seeking some sort of a technology or a technique which can extend their time within ice cold waters. Their wait seems to be now over as two professors from MIT have collaborated and have developed a way by which the survival time for conventional wetsuits increase.

The process they have developed is a very simple one and comprises simply the placement of the wetsuit inside a pressure tank which is filled with heavy inert gas for around a day. The treatment then last for as long as 20+ hours for people who need to spend more time in the water. After this the wetsuit is placed in a sealed bag and is opened only just before having to use the suit to dive into the water. The two professors realize that if trapped air is placed in a box which also holds the wetsuit, the insulating property of the wetsuit material increases extensively. This results in the lowest possible heat transfer of any wetsuit which has existed till date. The two professors set a world record by developing the lowest thermal conductivity wetsuit almost as if giving the feeling of wearing a coat of air.
