The field-dependent thermoelectric power of TaS3 is measured, and a general analysis of thermoelectricity in non-Ohmic conductors is applied. The Peltier heat coefficient of the nonlinear electric current is zero at high temperatures and independent of applied voltage at all temperatures. The present results are consistent with a moving condensate accompanied by low-temperature phonon drag, but not with certain alternative non-linear conduction mechanisms.
