1. The invention relates to an electrical power production system comprising a plurality of generator assemblies (Ega, Egb) that each include: at least one piezoelectric generator (Ga, Gb) suitable for generating electrical power in response to a mechanical force applied onto said first generator; an actuator (Aa, Ab) suitable for applying a mechanical force onto the generator (Ga, Gb) when said actuator (Aa, Ab) is biased; a rotatable cam (Ca, Cb) having a cam surface (Sca, Scb); a follower means (MSa, MSb) for following the cam surface (Sca, Scb); a lever (La, Lb) connected to the first follower means (MSa, MSb), said lever being mounted as a lever arm and engaging with the actuator (Aa, Ab) so as to bias said actuator when the cam (Ca, Cb) is rotated and the cam surface (Sca, Scb) exerts a mechanical force on the follower means (MSa, MSb); and a rotatable wheel (R) rotated by a power source. Said rotatable wheel is coupled to the cams (Ca, Cb) so that setting said rotatable wheel in rotation at a rotation speed (WR) causes the rotation of said cams at another rotation speed (Wca, Wcb), which is greater than that of said rotatable wheel. |
