"Assemblyman Mike Gatto Introduces Landmark Legislation to Capture Roadside Energy"
The technology, called “piezoelectric generation,” can produce as much as 44 megawatts of electricity per year from one single-lane, one-kilometer stretch of roadway — enough to power 30,800 homes for a year. The science works as follows: when a car or truck passes over pavement, the pavement vibrates ever so slightly. By placing relatively inexpensive piezoelectric sensors underneath a road, the vibrations produced by vehicles can be converted into electricity, which can be used to power roadside lights, call boxes and neighboring communities.
