Case Study: Israeli Roads

harvesting energy from vehicles
embedded the pavements with piezoelectric materials about 5 cm below the surface
energy produced from a 600v/h traffic flow:
- single lane road: 200kWh
- four lane road: 1.0MWh
setup: ten-meter strip of asphalt, with generators, and batteries placed
estimated service lifetime = 20 years
cost of implementation = $500,00 per km

harvesting energy from footsteps
Pavegen systems: have been used in the Paris Marathon (2013) and London Olympic games (2012), malls in U.K., and Riverdale Country School in New York City
designed pavement blocks or slabs to be placed in crowded urban environments
produce about 7 watts at 12 volts DC energy in a single step
- sufficient to light a LED street light for 30 seconds

This image is an example of how Pavegen Systems has implemented piezoelectric material in floor blocks to harvest pedestrian mechanical energy.
