The tidal power generator includes a hollow container, an impeller designed for unidirectional rotation, an electric generator fixed in the container, and a chargeable power source. A first opening and an opposite second opening are defined in the container. The impeller is positioned at the second opening and configured for unidirectionally rotating pushed by air flow. The electric generator includes a stator and a rotor extending from the stator. The rotor is fixedly connected to the impeller. The rotor rotates with rotation of the impeller so that the stator outputs electrical energy. The power source is configured for storing the output electrical energy.
