The relevance of (bulk) transition-metal oxides for thermoelectric generation is discussed. A large power factor (i.e., a large electronic conductivity coexisting with a large Seebeck coefficient) seems more easily achievable in either hopping-type semiconductors or in highly correlated metallic systems such as layered cobaltites.
