A linear rotary generator includes a magnet, a housing defining a cavity receiving the magnet, and a solenoid around the cavity. The magnet has a magnetic axis that rotates about a rotational axis as the magnet rolls along a direction perpendicular to the rotational axis. As the magnet passes through the solenoid, it induces an alternating current in the solenoid. The rotary power generator may be fixed to an object experiencing motion, which causes the magnet to roll in the housing and generate electricity for the object.
