Energy-harvesting tiles placed along an 80 foot section of the Champs Elysee will capture energy from the pounding feet of 40,000 racers. The technology offers a tangible way for people to engage with renewable energy generation. The flexible tiles made from recycled truck tires convert kinetic energy from foot traffic into useable, off-grid electricity. The tiles’ top surface is made from 100% recycled rubber and the base is constructed from over 80% recycled materials. The system is versatile: use it for new developments or retrofit existing flooring systems.
During Hajj, perhaps the largest annual pilgrimage in the world, mobs of Muslims walk counter-clockwise seven times around the Kaaba, the black cube-shaped building at the heart of the Al-Masjid al-Ḥarām. Imagine the juice those tiles could collect if installed around the plaza? In addition, pilgrims run repeatedly between the hills of Al-Safa and Al-Marwah. That makes for gargantuan power potential.
Pavegen Systems Ltd., the U.K. tile maker, says the technology is waterproof, designed to be used in harsh outdoor locations, and best suited to high-footfall urban environments.
The inventors estimate that each footstep generates up to 8 watts of kinetic energy, enough to power a light bulb for about five days. Harvested energy can be stored in an on-board battery or used immediately to power applications such as pedestrian lighting, way-finding solutions and advertising.
