Features: Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications such as CCD camera, picnic cooler, beverage cooler , alternate power sources, or even for your own custom car drink warmer/cooler.Since they consit primarily of semiconductor material sandwiched between ceramic plates and have no moving parts.It will even generate electricity if you apply heat to one side while keeping the other side cold.This device must be used in conjunction with a heat sink to avoid burned.
