To calculate the energy generated by a thermocouple, one must consider the specific materials used, as the temperature gradient directly influences the potential difference produced. A thermocouple measuring 2 inches wide by half a meter long with a 2000 degrees Celsius gradient will yield varying electricity outputs based on its composition. The feasibility of using a non-metal plasma as a secondary conductor instead of a metal is questioned, as traditional thermocouples rely on metal properties. Manufacturer specifications are crucial for accurate calculations, and additional details are necessary for precise energy generation estimates. Understanding the thermoelectric effect is essential for further exploration of this topic.
