At the recent Paris marathon the runners literally generated electricity. Pavegen put down a series of tiles that create an electric charge when compressed, so all they had to do was lay the tiles along the marathon route. The resulting energy generated by the runners was enough to power signs and screens during the event; the goal is to have the marathon fully powered by the runners themselves.
The flexible tiles made from recycled truck tires will span a portion of the Champs Elysees for about 25 meters (82 feet) of the 42.2-kilometer course, according to Pavegen Systems Ltd., the U.K. maker of the tiles. Each footstep generates as much as 8 watts of kinetic energy, which is fed back to batteries that can charge display screens and electronic signs along the route, the company said.
Schneider Electric SA (SU), the race sponsor, aims to eventually make the Paris Marathon an event that generates energy rather than consumes it, Aaron Davis, the companyâ€™s chief marketing officer, said in Pavegenâ€™s statement. London-based Pavegen aims for its tiles to help cut carbon emissions and boost energy efficiency in cities around the world in the future, it said.
