Abstract: A power generating brick comprising a brick body with a through hole provided along a vertical direction; a thermoelectric unit disposed in the through hole and comprising a heat collecting assembly, a thermoelectric power generation sheet and a heat sink; wherein, the heat sink is disposed at the lower end of the through hole; the thermoelectric power generation sheet is disposed on the heat sink; the heat collecting assembly is disposed on the thermoelectric power generation sheet; so as to generate electrical energy from a temperature difference between the cold and hot sides of the thermoelectric power generation sheet, and output electrical energy via wires connected to the positive and negative electrodes of the thermoelectric power generation sheet. The power generating brick can be laid on the pedestrian streets, squares, roads and roofs of a city or used as walls of a building.
