From step
to stored kWh.

Every plank of the bridge is a small power station. The energy system follows a deliberately conservative design used in transit hubs in London (Pavegen, 2017) and Tokyo (JR East, 2008) — proven, repairable, and easy to inspect.

In plain words

The same idea, with no technical words.

If the diagram below looks complicated, read this first. It's exactly the same journey, explained simply.

01

You walk

Your foot presses a floor tile down a tiny bit — a few millimetres you can't feel.

02

A spark is made

That little push runs a small generator inside the tile, making a short burst of electricity.

03

It gets tidied up

A small electronic part turns the messy burst into steady, battery-friendly power.

04

Cables collect it

Two wires under the deck gather the power from all 28 tiles into one line.

05

A controller decides

A smart box checks the battery and sends the energy where it's needed.

06

The battery saves it

The energy is stored until the evening — then it lights the bridge for free.

The path, drawn out

Watch the energy travel.

The dots show the energy flowing from a footstep all the way to the battery and out to the lights.

Seven stages, traceable end-to-end.

The same six simple steps, written the way an engineer would — with the numbers behind each stage.
