Abstract
An asymmetric flywheel is coupled to an input gear that is attached to a lever or alike. The input gear and flywheel gear are engaged as the user rotates the lever. As a result, the flywheel spins and electricity is generated by the micro electromagnetic generator. When there is no direct user manual input, the input gear and the flywheel gear are disengaged. The flywheel is an unbalanced pivoted mass that rotates with inertial forces from physical accelerations by user's movement and gravitational forces, similar to a self-winding mechanism automatic watch. AC electricity is generated as a result of the flywheel's movement.
