Abstract: A thermoelectric generator sleeve is adapted to be attached to a base of an electrical socket, which has one or more light bulbs (Incandescent, Fluorescent, LED, etc.). The heat created by the light bulbs is absorbed by the thermoelectric generator sleeve that allows the efficient conversion of heat energy into electrical energy by using thermoelectric generators. The aesthetically designed spatial configuration of the thermoelectric generators provides efficient thermal energy conversion and storage for the converted heat energy. Additional electronic circuitry to regulate the energy produced is holistically integrated into the thermoelectric generator sleeve to provide added functionality and safety.
