Paris Goes Green

The Energy-harvesting Tile

Sunday's Paris Marathon was the platform for a progressive initiative to convert the energy used by runners into a renewable source. Energy-harvesting tiles were laid across 82 feet of the Parisian course, meaning the footsteps of the 40,000 runners taking part were converted into kinetic energy.

The tiles, which are made from recycled truck tyres, were laid out near the beginning of the race as runners moved through the Champs-Elysées. Each footstep is said to have generated as much as 8 watts of kinetic energy, which was then used to power electric signs and display screens along the route.

The technology has been invented by London based company Pavegen Systems, who hope the tiles can be used to reduce carbon emissions and boost energy efficiency in cities around the world. Schneider Electric SA, sponsors of the Paris Marathon, are hopeful that the event will eventually become energy producing.

Pavegen Chief Executive Officer Laurence Kemball-Cook commented: "Imagine if your run or walk to work could help to power the lights for your return journey home in the evening. It's a viable new type of off-grid energy technology that people love to use and which can make a low-carbon contribution wherever there is high footfall, regardless of the weather."
