Considering the obesity rate in the country and the FitBit craze, this could be a win-win for all of us.
Children have been harnessing energy from their steps ever since 1992, when L.A. Gear introduced sneakers that light up. For most adults, however, the ambient energy created by the simple act of walking is forever lost. Considering that the average person takes around 216 million steps in a lifetime, it’s a significant waste.
Inventor Laurence Kemball-Cook hopes to harness the lost energy at two points of contact: the shoe and the floor. In 2009, Kemball-Cook founded Pavegen, a company whose floor tiles can capture the power of footsteps. The technology uses compression to skim a tiny fraction of the energy created when a human steps on the tile. It’s been installed in more than 100 projects around the world, including a football stadium in Rio de Janeiro and a terminal in Heathrow Airport. The energy is stored in batteries inside the tiles, where it can then be used to power lighting, advertisements, and way-finding solutions, which guide people through an environment via directional arrows.
Now Kemball-Cook and his R&D team have turned their attention to the shoe itself, hoping to apply the same principles used in the tiles as a way to harness personal energy. “The idea is that the energy source would be readily available to the shoe wearer,” explains Kemball-Cook, who has been in discussions with major footwear manufacturers such as Nike and Reebok about ways the technology could be incorporated into consumer products. “You could walk from work and charge your phone en route instead of waiting to use a charger at home. Runners could charge their music players during a jog.”
