While cars, computers, and a wide range of other technologies have benefitted from new designs and novel advances, the elevator has lagged behind. In most buildings, elevators still use the same cable-based system they did when they were invented. But some are working to revolutionize this system with the same technology used by high-speed rail: magnets. By using electromagnets to create linear motors that would drive each elevator car on a cushion of air, an elevator system would be freed of its cables and allowed to move in all directions.
Who Invented The Elevator?
Evidence suggests that the first elevator may have been built in ancient Rome.
