Manufacturing facility line and thermoelectric power generation method

The invention provides a manufacturing facility line and a thermoelectric power generation method. According to the present invention a thermoelectric power generation device having thermoelectric power generation units is provided to a manufacturing facility line the thermoelectric power generation units face heat sources and are disposed in accordance with the temperature of at least one of the heat sources and/or the output of the thermoelectric power generation units. As a result a manufacturing facility line in which heat sources are moved can be achieved with which thermal energy of the heat sources having fluctuating emission states can be efficiently converted into electrical energy and recovered.
