Mechanical movement exerted upon or over roadways is transmitted and converted to mechanical movement conducive towards the production of electrical energy. In one disclosed system, ramped or angled push bars are disposed within a roadway, such that a front set of bars and back set of bars will not be moved simultaneously. A series of one way values may enable subterranean fluid chambers to move a pendulum flywheel or rotor in a continuous direction or in a back and forth movement.
