Escalator
From Tardis Wiki, the free Doctor Who reference
Jack Robertson's hotels used escalators to get between floors. (TV: Arachnids in the UK)
In Carthage in 1164 BC, Vicki Pallister lamented that escalator would not be invented for several thousand years. She once tried to describe the general concept to her husband Troilus but he did not understand it. (AUDIO: Frostfire)
