Abstract
One or more piezoelectric elements are employed to generate electrical energy from one or both of the mechanical energy of a moving part of a conventional engine or vehicle or the combustion energy of an internal combustion engine. The generated electrical energy can be stored and used to power an electric motor in order to supplement the power generated by the conventional engine.
