An efficient electrical power generator employs a plurality of piezoelectric devices in a rigid container. The top cover of the rigid container is capable of moving and in direct contact with a large hydraulic cylinder. A small cylinder, hydraulically coupled with the large one, through tubing is capable to displace a liquid contained in the tubing. An input force applied on the small cylinder, is multiplied by the large cylinder, which compresses the piezoelectric devices causing them to produce an electrical output
