SUMMARY
This discussion centers on the operation of thermoelectric devices and their compliance with the second law of thermodynamics. Thermoelectric devices convert heat into electrical energy by exploiting a temperature difference between two plates, known as the hot and cold reservoirs. The conversation highlights that while adding heat to a wire generates an initial current, it quickly reaches thermal equilibrium, ceasing current flow. In contrast, thermoelectric generators (TEGs) maintain a temperature gradient, allowing them to operate efficiently and produce electrical work below the theoretical limits set by thermodynamic laws.
