Green Pavement makes Electricity

Paving slabs that convert energy from people's footsteps into electricity are set to help power Europe's largest urban mall, at the 2012 London Olympics site.

The recycled rubber "PaveGen" paving slabs harvest kinetic energy from the impact of people stepping on them and instantly deliver tiny bursts of electricity to nearby appliances. The slabs can also store energy for up to three days in an on-board battery, according to its creator.












The Potential
"Up to 52,000 people per hour pass through busy train stations. The average person takes around 200 million steps in their lifetime."







Although each step produces only enough electricity to keep an LED-powered street lamp lit for 30 seconds, Kemball-Cook says that the tiles are a real-world "crowdsourcing" application, harnessing small contributions from a large number of individuals.
"We recently came back from a big outdoor festival where we got over 250,000 footsteps -- that was enough to charge 10,000 mobile phones," said Kemball-Cook.
