<P>PROBLEM TO BE SOLVED: To provide a power generator by thermoelectric generation corresponding to a peak of power demand by utilizing overheat of asphalt such as a road and can be sited at a place near a demand place. <P>SOLUTION: A polar plate A is installed just under an asphalt road surface which becomes a high temperature heat source, the polar plate A being in contact with the asphalt road surface. After that, a polar plate B and a polar plate C are installed so as to contact with water supply and sewerage pipes, a water storage groove, etc. which become low temperature heat sources. The polar plate B and the polar plate C do not come in contact with each other. The polar plate A and the polar plate B are connected with each other in a vertical direction with a p type semiconductor therebetween. The polar plate A and the polar plate C are connected with each other in a vertical direction with a n type semiconductor therebetween. The polar plates B, C are mutually connected by a conducting wire to configure a closed circuit. When heat is inputted to an asphalt road surface such as a road which is the high temperature heat source, a temperature difference is generated between the asphalt road surface and the water supply and sewerage pipes, etc. which are the low temperature heat sources. Consequently, a direct current is generated along a direction of the order of the p type semiconductor, the polar plate B, the conducting wire, the polar plate C, the n type semiconductor, the polar plate A, and the p type semiconductor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
