PROBLEM TO BE SOLVED: To generate power by melting snow by utilizing thermal energy in which underground water or sewage has and simultaneously utilizing their thermal energy. SOLUTION: A metal plate 2 is provided on one end of a plurality of thermoelectric elements 1 connected mutually electrically, the surface of the metal plate 2 is made a snow mounting face, a pipe 4 flowing underground water is brought into contact with the other end of the thermoelectric element 1, so that snow can be melted by thermal energy in which underground water has, and power is generated by Seebeck effect by giving a temperature difference on both the thermoelectric elements 1. Snow can be melted with thermal energy possessed by sewage by bringing the other end of a heat pipe 9 immersing one end in sewage C into contact with the other end of the plurality of the thermoelectric elements 1, and power is generated by Seebeck effect by giving a temperature difference on both the ends of the thermoelectric element 1.
