"Pavegen" manufactures energy generating sidewalks. I.e. Pedestrians generate electricity (approx 2.1 watts per hour per panel) just by walking.
These could be use to generate electricity from foot traffic at security check points, bathrooms, security entryways, tracks or even roadways etc --- anywhere where there is heavy foot traffic.
This not only helps with generating electricity but also helps to move the government into the green age.
