Abstract
An electrical power production system including a plurality of generator assemblies having: at least one piezoelectric generator for generating electrical power in response to a mechanical force applied onto said first generator, an actuator for applying a mechanical force onto the generator when said actuator is biased, a rotatable cam having a cam surface, a follower means for following the cam surface, a lever connected to the follower means, said lever being mounted as a lever arm and engaging with the actuator so as to bias said actuator when the cam is rotated and the cam surface exerts a mechanical force on the follower means, a rotatable wheel rotated by a power source and coupled to the cams so that setting said rotatable wheel in rotation at a rotation speed causes the rotation of said cams at another rotation speed, which is greater than that of said rotatable wheel.
