Free convection and electrical generation with thermoelectrics

The main advantage of thermoelectricity compared to conventional techniques of refrigeration and electricity generation lies in the absence of mechanical parts such as motors and compressors. Free convection based exchangers yield maximal safety due to the absence of fan or pump. We describe an electricity generating thermoelectric unit of the above type; it is designed for a small nuclear-powered submarine suitable for deep sea oil prospection. The purpose of the unit is to power an alarm system in case of reactor failure.
