Abstract
In a power generating mechanism, a heat sink is mounted on a CPU of a notebook PC to diffuse heat generated by the CPU. A Seebeck element module is mounted in the heat sink to cause a large difference in temperature based on heat emitted from the heat sink and ventilation carried out by a fan unit. Electromotive force obtained from the Seebeck element module is used to drive selected components of the notebook PC.
