Pedestrians to power walkway to London 2012 Olympic park

A pioneering walkway leading to the Olympic Park will be lit round-the-clock by the footsteps of a million spectators during the London 2012 Games. The award-winning British renewable technology has been commissioned by the Olympic Delivery Authority (ODA) to light the temporary bridge leading from West Ham Station - one of the three transport hubs feeding the London 2012 Games - to the Olympic Park.
Twelve energy harvesting floor tiles along a walkway connecting the Station to the Greenway walking route to the Olympic Park, are expected to receive more than 12 million impressions, generating 72 million joules of energy - enough to power a small electric car for 397 laps of the Olympic athletics track or charge 10,000 mobile phones for an hour.
The power will be used to illuminate the walkway for eight hours at full power during the night, and 16 daylight hours at half power. As well as 24-hour lighting, the units will also produce an energy surplus of around thirty five per cent, to be stored as a contingency in batteries onboard the units.
ODA Transport Director, Hugh Sumner said: "The widespread use of energy-efficient technology is one of the main features of London 2012. This foot-powered lighting system for one of the main walkways into the Olympic Park is just one of the many sustainable initiatives the ODA have deployed during the Games and will really get people thinking about how an individual can make a difference, while getting to and from their events."
David Stubbs, Head of Sustainability at the London Organising Committee (LOCOG) said: "We want people coming to the Games to be able to do their bit for the environment and this is a great example where, literally in a few steps, people can actively contribute towards making these truly sustainable Games."
The tiles were produced by British renewable energy terchnology company Pavegen Systems Ltd. The units each contain wireless transmitters able to send information via the web, allowing both spectators and organisers to monitor how much renewable energy is being generated via their computers and smartphones. This information will both reward and inform visitors, but could also enable the operators of this and similar events, to better understand and manage traffic flows.
