Architects will be able to create escalators in any shape they want, even freeform curves, thanks to the first significant rethink of escalator design since the 'moving stairway' was invented in 1897. A system known as the 'Levytator' has been developed by Jack Levy, an Emeritus Professor of Mechanical Engineering at City Univ. London. Unlike traditional designs, where redundant steps move underneath those in use, the Levytator utilizes a continuous loop of curved modules, which can follow any path upwards, flatten and straighten out, and descend once more, all with passengers onboard.
