Viva / Seawater energy jacket

people will meet several dangers in water-sport, such as drowning, cold and requiring additional equipment for rescue. Some of these problems can be solved by using lifejacket, but not the hypothermia.

Normal body temperature is 37 grad, If the core body temperature decrease to lower than 35°C, people would already lain on a bed in hospital. When below 28 grad, there be no vital signs. People will lose grads easily in cold water, specially sick people.

Unfortunately, most of people don't really pay attention to Hypothermia. To prevent people from hypothermia danger, I designed Viva, which use the natural energy from seawater and metal.
