Large scale array of thermoelectric devices for generation of electric power

A thermoelectric power generating device is assembled from multiple thermoelectric elements disposed in a chip structure, the chip structure forming a power generating core. Multiple cores are stackedwithin a thermal container such that thermal energy provided at a first end of the thermal container is delivered in a serial manner to the stacked cores. The thermal container includes heat absorbers, heat reflectors and heat transmission barriers so that minimal thermal energy is lost through the walls of the container and maximum thermal energy flows from the heat source through and past the cores to an ambient temperature end of the container so as to create a controlled temperature differential from the hot end to the cooler end of the container as well as across each core stacked therein. The temperature differential across each core results in the generation of electrical energy, such electrical energy being collected by standard power utilization techniques.
