Btw, if traffic is stopped(idling) then power output is zero. It generates only when traffic is moving on and off the sections with piezo elements as it is the movement (change in stress) that creates the power. The most familiar version of piezo that almost everyone has at home is the lighter, where you squeeze a trigger to get a spark. That spark is generated because the trigger bends the piezo crystals inside the lighter. Cor
