Power is recovered from an escalator or a moving walkway as the step orbits an endless track on rollers. A generator is connected to a roller orbiting the track. A battery backup is provided. The power is used for emergency lighting on the step, and for data transmission. Advertising and messages are displayed on a dynamic video screen mounted on the step. The apparatus is mostly contained within the escalator step. Information is communicated wirelessly to a remotely located central control station and back to the step, so as to display information in real time and to update advertising while the escalator is in operation. The central control station also monitors performance parameters. The visual display can include LED lighting.
