LIQUID METAL THERMOELECTRIC GENERATOR

摘要

A liquid metal thermoelectric generator comprises a containment chamber (2) for at least one liquid or liquefied metallic material, heating means (3) for heating the containment chamber (2) adapted to promote the expansion of the liquid or liquefied metallic material, a transmission element (4) operatively in contact with the liquid or liquefied metallic material to move upon the expansion thereof, means (5) for generating an electromotive force operatively associated with the transmission element (4). These latter comprise a magnetic or electromagnetic circuit (6) powered by an electric current for generating an electromagnetic field and having at least one movable junction element (7) operatively coupled to the transmission element (4) to move between a first closing position of the circuit (6) and a second opening position of the circuit (6) upon the transmission by the transmission element (4) of a force greater than the electromagnetic attraction acting on the movable junction element (7) to produce a variation of the flow of the field adapted to generate the electromotive force.
