In Short- this is a prototype of a device that would heat or cool you with a device the size of a large watch.

The article is portraying it as an energy saver, but I wonder if if could be used to help with either heat stroke, or with hypothermia.


The approach is somewhat similar to what Stanford Research was using on their Cooling Glove, used for cooldown after exercise.
