This is not about rolling resistance, the energy harvested is removing a little bit of potential power, due to the road surface moving a little lower when the vehicle drives on it, so for the vehicle it resembles a slight incline to get out of, increasing the amount of energy the vehicle needs to spend by a small amount (no free energy) so it costs the passing motorists fuel to power the piezo road. There have been videos of this technology powering a charging station and sign to thank passing motorists for providing the power. The power output is small though. Running a display sign is no problem but don't think about fast charging. Cor
