Energy storing device and method of using the same

A ball, comprising:

• a shell defining a spheroid and having a cavity disposed therein, the shell comprising an opening and a panel configured to close the opening, the panel having a sleeve extending radially inward from an inner surface thereof;
• a generation module disposed in the cavity and fixed relative to the shell, the generation module comprising:
• a housing;
• a pendulum, an electric generator, and a battery disposed in the housing, a rotor of the electric generator mechanically coupled to the pendulum at a first axis of rotation of the pendulum, the electric generator electrically coupled to the battery;
• wherein the generation module is configured such that an acceleration of the ball relative to a playing surface causes the pendulum to rotate about the first axis of rotation;
• wherein the generation module is configured such that the rotation of the pendulum rotates the electric generator which generates electrical energy, at least a portion of which is stored by the battery;
• a socket disposed at least partially within the cavity and accessible from an outside surface of the shell, the socket electrically coupled to the battery and configured to transmit electrical energy from the battery to a device disposed externally relative to the ball, the device requiring electrical energy for operation.
