Abstract
A thermoelectric device has a cylindrical structure with a hollow central annulus member in which a fluid is pumped so that the heated fluid is pumped from the center of the structure and discharged on the outer surface of an outer annulus member or with the reversal of electrical current, the heated fluid is pumped from the outer periphery and discharged in the central tube. A plurality of thermoelectric cells are positioned in the space between the inner and outer annulus members with the cells being radially directed relative to the axis of the inner annulus member. A thermoelectric device having a similar structure may be used for the conversion of thermal energy to electrical energy when a thermal gradient is imposed between the inner member of the structure and the peripheral surface.
