A Thermoelectric-Based Point of Use Power Generator for Steam Pipes
A robust thermoelectric-based point of use power generation system with no moving parts that is designed to be clamped onto the outer wall of a steam pipe with a temperature of 160˚C plus was built and tested in ambient temperatures from 30 to 85˚C. The system consists of a pair of assemblies mounte...
