Personal Cooling System

Summer is hot. And we all need to find ways to cool down. So I built a thermoelectric cooling system that can mount to your wrist. A thermoelectric element acts like a miniature refrigerator. It can turn electricity directly into a change in temperature. By adding a heat sink, you can improve the efficiency of the cooler. This apparatus gets mounted to your wrist right above your radial artery. At this point there is a lot of blood moving near the surface. By cooling this point your blood helps to distribute the cooling effect over your whole body. It looks ridiculous, but it works.
