The author’s patented thermoelectric generator system uses a steam pipe as a heat source and ambient cooling in an exterior location at the Agricultural University of Iceland. This produces up to 7.2 watts (W) steady state using 6 thermoelectric modules.
The system has been powering a 3G webcam system since 2017 while it’s surplus power trickle charges 12 volt (V) batteries. New low power monitoring options originally developed for photovoltaic systems can be easily retrofitted for improved efficiency, additional and control options. The test results confirm the viability of a thermoelectric generator as power sources for security systems.
