Pedestrian footsteps, converted into energy


If the energy people expend dancing and working out can power cellphones, lights and other electrical appliances, why not apply the same notion to all the energy spent by millions of people every day simply walking along city sidewalks? That's precisely the idea behind Pavegen slabs, which can be inserted among regular sidewalk sections to capture the kinetic energy people spend just walking.

Each rubber slab from UK-based Pavegen Systems gets depressed by about 5 mm each time it gets stepped on. Using just that small movement, it can convert the kinetic energy used into electricity, which is then stored in the slab. Specifically, 5 percent of the energy harvested is used to make the slab's LED glow, making it clear to users that their energy has been captured. The rest can be used to power pedestrian lighting, information displays and many other applications. Pavegen's patent-protected technology has also been used to harvest energy from users' footsteps on stairs; custom branding is available.

Following recent tests in East London, Pavegen is now seeking both investors and additional testing sites for its eco-iconic innovation.
