How Energy-Generating Sidewalks Work
These innovative pavings convert the kinetic energy of footsteps into clean electric energy.

When your foot pushes down on the floor, the flywheel spins, rotating a coil of wire in the presence of a magnetic field, which produces an electric current. To give you a feel for these units, lifting a textbook off the floor and putting it on a table takes about 10 joules of energy.
