Some materials exhibit thermoelectricity, a phenomenon not only useful for heating and cooling applications but also for power generation. In his Perspective, Tritt describes results reported by Sales et al. (p. 1325) on a class of thermoelectrics called skutterudites. These compounds are promising higher performance in applications such as deep space probes, new generation automobiles, and temperature stabilization.
