Due to the well-known advantages of thermoelectricity, such as reliability, reduced maintenance and scalability, the present paper studies the possibilities of thermoelectric generators, devices based on solid-state physics, to directly convert fumaroles heat into electricity due to the Seebeck effect. For this purpose, a thermoelectric generator composed of two bismuth-telluride thermoelectric modules and heat pipes as heat exchangers was installed, for the first time, at Teide volcano (Canary Islands, Spain), where fumaroles arise in the surface at 82       \u2218  C    . The installed thermoelectric generator has demonstrated the feasibility of the proposed solution, leading to a compact generator with no moving parts that produces a net generation between 0.32 and     0.33        W    per module given a temperature difference between the heat reservoirs encompassed in the 69\u201386       \u2218  C     range. These results become interesting due to the possibilities of supplying power to the volcanic monitoring stations that measure the precursors of volcanic eruptions, making them completely autonomous. Nonetheless, in order to achieve this objective, corrosion prevention measures must be taken because the hydrogen sulfide contained in the fumaroles reacts with steam, forming sulfuric acid.<\/jats:p>","DOI":"10.3390\/s20123547","type":"journal-article","created":{"date-parts":[[2020,6,23]],"date-time":"2020-06-23T09:05:33Z","timestamp":1592903133000},"page":"3547","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Prospects of Autonomous Volcanic Monitoring Stations: Experimental Investigation on Thermoelectric Generation from Fumaroles"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0140-6689","authenticated-orcid":false,"given":"Leyre","family":"Catalan","sequence":"first","affiliation":[{"name":"Department of Engineering, Institute of Smart Cities, Public University of Navarre, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Araiz","sequence":"additional","affiliation":[{"name":"Department of Engineering, Institute of Smart Cities, Public University of Navarre, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Aranguren","sequence":"additional","affiliation":[{"name":"Department of Engineering, Institute of Smart Cities, Public University of Navarre, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"German D.","family":"Padilla","sequence":"additional","affiliation":[{"name":"Instituto Volcanologico de Canarias (INVOLCAN), 38320 San Cristobal de La Laguna, Spain"},{"name":"Instituto Tecnologico y de Energias Renovables (ITER), 38600 Granadilla de Abona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro A.","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Instituto Volcanologico de Canarias (INVOLCAN), 38320 San Cristobal de La Laguna, Spain"},{"name":"Instituto Tecnologico y de Energias Renovables (ITER), 38600 Granadilla de Abona, Spain"},{"name":"Agencia Insular de Energia de Tenerife (AIET), 38612 Granadilla de Abona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nemesio M.","family":"Perez","sequence":"additional","affiliation":[{"name":"Instituto Volcanologico de Canarias (INVOLCAN), 38320 San Cristobal de La Laguna, Spain"},{"name":"Instituto Tecnologico y de Energias Renovables (ITER), 38600 Granadilla de Abona, Spain"},{"name":"Agencia Insular de Energia de Tenerife (AIET), 38612 Granadilla de Abona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celestino","family":"Garcia de la Noceda","sequence":"additional","affiliation":[{"name":"Instituto Geologico y Minero de Espa\u00f1a (IGME), 28003 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose F.","family":"Albert","sequence":"additional","affiliation":[{"name":"GAIA Geotermia y Aguas Minerales S.L., 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Astrain","sequence":"additional","affiliation":[{"name":"Department of Engineering, Institute of Smart Cities, Public University of Navarre, 31006 Pamplona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,23]]},"reference":[{"key":"ref_1","unstructured":"(2020, January 16).
