Abstract:

Thermoelectric energy harvesting was studied using the temperature difference in concrete bridges. A design of the heat sink unit of thermoelectric energy harvesters was parametrically analyzed using FE models. Prototype thermoelectric energy harvesters were fabricated and tested in a simple wind tunnel. The experiment was carried out on a concrete bridge. The concrete bridge accumulated thermal energy from sunlight, and the temperature difference with the air occurred. The thermal energy was harvested especially in daytimes. On the other hand, electric power was less generated at night-times than expected. The harvesting energy would be significantly improved if the problem is solved.
