These things seem to repeat over and over:
1) roads paved with solar cells
2) roads with rotary fans next to them that collect "free energy" (actually saps mpg from trailing cars / increases gas usage / just add gas tax instead)
3) sidewalks that depress and generate free electricity as people walk on them (old people, wheel chairs, kids, etc)
Small solar makes sense to charge some small stuff in the event of power loss. Or a small panel that keeps the car battery topped up, that kind of thing.
