Energy harvesting pavement powers its own streetlights.
London-based startup Pavegen has developed tiling that can harvest kinetic energy from people’s footsteps, turning it into up to 8 watts of electricity per footstep.
The tiles are made of 95 percent recycled tyres, and use a proprietary wireless communications technology to transmit data about the number of footfalls and the energy generated via the Internet. A wireless network of the tiles could provide valuable information to city planners and nearby business owners about the number of pedestrians in the area at different times of the day.
At the last Summer Olympics in London, the tiles were installed outside a tube station where they generated enough energy to power lights in the area for five hours a night.
