Here’s an interesting device to take advantage of those bumpy roads to generate electricity.
Bike Generator Harnesses Power From Bumps on the Road
TreeHugger has shown all kinds of generators for bicycles, but here is a novel approach that would do well where I ride. Industrial designer Deco Goodman takes advantage of our crumbling infrastructure and pothole-filled roads by installing a piezo-electric generator in a shock absorber built into the seat post. Every tooth-jarring bump now is a little bit softer as the energy is converted to electricity and stored in the battery.
