One step closer to sustainability

A state-of-the-art walkway lights the way to the Olympic Park

Among the various eco-sustainable projects implemented for London 2012, one of the most interesting ones is the pioneering walkway connecting West Ham Station to the Olympic Park. This will be lit round the clock by the footsteps of spectators passing through. It is made possible thanks to twelve special energy harvesting floor tiles produced by the British company Pavegen, specialized in renewable energy and technology. It has been estimated that the tiles will receive over 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 sixteen daylight hours at half power. The units will also produce an energy surplus of around 35%, which will be stored in the batteries. David Stubbs, Head of Sustainability at the London Organizing Committee 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 Games truly sustainable".
