Paris Marathon will harvest energy from runners

Watching a big city marathon is an incredible sight. Wave after wave of runners voluntarily running along city streets, expending enormous amounts of energy to cross the finish line 26.2 miles from the start. And at the Paris Marathon this weekend at least some of that energy produced by the estimated 40,000 runners won’t be wasted.

The race, sponsored by Schneider Energy, will cover 82 feet of the course with tiles that collect energy from footsteps and turn them into kinetic energy that’s collected in a battery and used to power electric signs and display screens along the race route, Bloomberg reports. Every footstep can generate as much as 8 watts of energy.

The energy harvesting tiles are made by Pavegen Systems http://www.pavegen.com/ , a London-based company, which says its tiles are the "first tangible way for people to engage with renewable energy generation."
