An electricity generation device contains a rotational arm (1), a weight (2), and a moving mechanism (3). The rotational arm (1) is rotatable joined to an electricity generation mechanism (4) and configured with a track element (11) along its length. The weight (2) is movably configured in the track element (11). The moving mechanism (3) applies a first moving force to move the weight (2) from a first end side of the rotational arm (1) along the track element's length to a second end side opposite to the first end side. A torque is thereby produced to turn the rotational arm (1) and electricity is generated by the electricity generation mechanism. Also an electricity generation method is provided. |
