I know there have been some applications of piezoelectric floors put in places people walk (to generate small amounts of electricity). I wonder if this could have some practical value in roads. The energy would be small, but perhaps it would be enough to keep some distant electronic systems fed.
- mkl 7y agoA solar panel is probably a better option. That's how some illuminated signs and environmental sensors are powered around here.
- thombat 7y agoThe problem with piezoelectric flooring is that the power generated is "stolen" from the person crossing it. Take too much power, e.g. by having a perceptible deformation of the surface, and the person will have the feeling of walking on soft sand or snow and may avoid walking on it. Take too little and the exercise becomes pointless: even with a very generous set of assumptions the PaveGen system produced 1/5000th of a person's power need.
