People installed kinetic paving slabs around an area in London. These slabs generate energy from people’s footsteps as they walk over them.

The electricity can be stored in batteries, or it can power a street light, for example. One of the installations powers two streetlights in the heart of the financial district.

This new technology can also send wireless data, using the energy from footsteps. People already installed the tiles in many other locations worldwide.

Difficult words: kinetic (relating to motion), paving slab (something flat and thick which people can step on), district (an area of a city), tile (a thin slab).
