Kinetic pavement generates extra energy at Olympics

A temporary footbridge by London’s Olympic Park is being fitted with 12 energy-harvesting tiles designed to generate additional electricity during the Games.

Made from recycled lorry tyres and recycled aluminium, the tiles flex 5mm when stepped on, which creates the electricity. The company behind the tiles – Pavegen Systems – is elusive about the precise technology it employs, but according to an interview last year with The Engineer, the Pavegen team has invented a hybrid solution which takes advantage of the ability of certain materials to transform mechanical strain into an electric charge.

Forecast to generate a total of 21 kilowatt hours of electricity over the course of the Olympic Games, the tiles are unlikely to make a significant dent in the event’s overall energy use. However, as the company’s video highlights below, the installation could signal the mainstream uptake of a new renewable energy source.
