Abstract.Recently a formula for the variance of the thermal voltage between the ends of a conductor has been proposed. We discuss this formula with regard to possibilities of manipulating the thermal voltage. In particular, utilizing the dependence of the variance of the voltage on the density of the electronic gas confined to the conductor, we point out a possibility of voltage amplification by the exposition of the conductor to an electrostatic field. This possibility is noteworthy insofar as it necessitates only negligible input of electric power.
