Green sidewalk produces electricity

A 25-year-old engineer has developed pavement slabs that convert footsteps into electricity.

The “PaveGen” slabs harvest the kinetic energy that is produced from people stepping on them into small amounts of electricity that is sent to nearby appliances. The slabs can also store energy for up to three days.

Twenty tiles are planned for the crossing between London, England’s Olympic stadium and a new mall, the largest urban mall in Europe. The mall expects 30 million visitors in its first year. That should be enough footsteps to power half of the mall’s outdoor lighting needs.

The technology was recently used at an outdoor festival where 250,000 footsteps was enough to charge 10,000 mobile phones.
