If the rails are solid state using for example magnetic levitation, I can see this being much cheaper to maintain.

- samstave 9y agoEver been in an elevator during a power outage?
- dom0 9y agoProbably no one at ThyssenKrupp thought of that. You should write them a letter outlining your concerns.
- mschuster91 9y agoNo problem either - do it like on freefall towers or on other park attractions, where eddy current brakes, fully passive, are employed as safety mechanism.
- dom0 9y agoAll elevators have multiple safety brakes working on their guide rails (this is the famous invention of Otis); so do these. Besides batteries lasting longer (two hours, they say) than the median European power outage.
- CydeWeys 9y agoPlus hopefully battery banks (which you'll likely want on the elevators anyway to be able to store energy from regenerative braking) to power the car long enough to come to a rest where the passengers can get out in the event of a power outage. There's going to be several layers of safeguards, like there are with current elevators.
