Prospects of autonomous volcanic monitoring stations: experimental investigation on thermoelectric generation from fumaroles

Fumaroles represent evidence of volcanic activity, emitting steam and volcanic gases at temperatures between 70 and 100 °C. Due to the well-known advantages of thermoelectricity, such as reliability, reduced maintenance and scalability, the present paper studies the possibilities of thermoelectric g...
