NOVELTY - A thermoelectric power generator and storage module (1) comprises: at least one n-type thermoelectric element (2) thermally and electrically coupled to at least one p-type thermoelectric element (4), where the figure of merit (ZT) of the thermoelectric power generator and storage module is greater than 1.    USE - As a thermoelectric power generator and storage module (claimed) for generating and harvesting energy; in incinerator and exhaust applications, such as in a factory, power station, household furnace, automobile or any other industrial heat producing process, in power small devices and sensors requiring low power from low temperature gradients such as body heat, and in heat pumps (thermoelectric cooler), solar thermoelectric converters, thermoelectric sensors, thermal imaging and many other applications that can benefit from the production of electricity from heat.    ADVANTAGE - The figure of merit (ZT) of the thermoelectric power generator and storage module is greater than 1. The current bulk thermoelectric materials and devices have relatively low figures of merit (ZT) on the order of less than or equal to 1. The p-type and n-type thermoelectric materials and devices have a figure of merit of greater than 0.65 (preferably greater than 2).    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) new n-type thermoelectric material having a composition of formula (Sr1-xBax)1-yD'y(Nb1-yD'y)2Oz and having a figure of merit (ZT) greater than 0.5 or a composition of formula (Sr1-xD'x)2(Nb1-xD'x)2Oz;    (2) new p-type thermoelectric material having a composition of formula Li1-x'NbO2, and having a figure of merit (ZT) greater than 0.5; and    (3) manufacturing a thermoelectric power generator and storage module involving: providing several n-type thermoelectric elements and several p-type thermoelectric elements; thermally and electrically coupling each n-type thermoelectric element to a p-type thermoelectric element in layered stacked monoliths to form interconnected n-p regions.    x=0-1;    y= less than or equal to 1;    z=5-7;    x'=0-0.5;and    D'=dopant La, Y, Yb, Ti, Ta, V, W, U, or Mo.
