ABSTRACT:
Electric power is generated downhole in a well using a thermoelectric device. A temperature gradient or differential .DELTA.T present in the well is applied to the thermoelectric device to produce a voltage potential across the output terminals of the device. The thermoelectric device includes a first thermocouple coupled to a heat source and a second thermocouple coupled to a heat sink source. The electric power generated by the thermoelectric device is used to recharge battery packs located downhole or to power electrical devices or systems.
