Electrical power generating system

摘要

An electrical power generating system is disclosed which utilizes as a source of energy the otherwise wasted energy expended by motor vehicles moving along a roadway. The system includes a vibrational transducer which is mounted in the roadway and which is constructed for producing electrical energy directly from the vibrational energy imparted to the transducer from the motor vehicles passing thereacross. The electrical energy thus produced may be used to charge a storage battery for powering various devices, such as traffic signals, warning devices, and the like.
