NOVELTY - The thermoelectric generator comprises a petrol lamp (10), one or more thermoelectric converters (24) with thermocouples whose hot junctions associated with interior radiators (26) are in thermal contact with hot gases produced by the lamp and whose cold junctions are in thermal contact with ambient air by the intermediary of an exterior radiator (22), and a heat-insulating duct (20) for the passage of hot gases. The heat-insulating duct (20) is mounted in the upper part of the lamp above the flame and opens up in a cylindrical space where wings of the interior radiators (26) are extended. The thermoelectric converters are of semiconductor type.    USE - Used for supplying power to electronic apparatus such as a transistor radio and for recharging a mobile telephone.    ADVANTAGE - The generator has higher electric power than previous devices.    DETAILED DESCRIPTION - The thermoelectric converter (24) is in the form of a parallelepiped block serried between the interior radiator (26) and the exterior radiator (22). The interior radiator and the exterior radiator are linked by tightening means of type screw-nut associated with elastically deformable elements for absorbing the differential constraints of thermal expansion. The separating elements (50) made of thermally insulating material are interposed between the converter and the tightening means. The generator comprises two thermoelectric converters laid out diametrically opposite with respect to the axis of cylindrical space, or several thermoelectric converters laid out around the axis, and mounted between the exterior radiator one or more interior radiators whose wings are extended in the cylindrical space. The space between the interior radiators and the exterior radiator is filled with a refractory thermally insulating material, for example glass wool. The set formed by the exterior radiator, the interior radiators and the thermoelectric converters is carried by the heat-insulating duct (20), and can be displaced vertically with the duct when lighting the lamp.
