One function of elevator cables is the emergency brake system (fail closed) — hope the power in this mag system is really really redundant!

"One function of elevator cables is the emergency brake system "

With this maglev system (as with conventional elevators, trains and trolleys), there is a speed governor system. When the governor spins too fast, the centrifugal force activates a braking system.

It could still have the type of safety brake that mounts under the car and engages when excessive downward motion is detected.

Maybe they are based on electropermanent magnets - ie. defaults to on, current switches off.

I'm not sure how the elevator works, but if you've ever tried to toss a magnet down a copper tube, it appears to defy gravity - no electricity involved. Something similar could work to create a "fail-proof" elevator.

I'm guessing there is a mechanical failsafe in place, but I want to see test data proving it works before I get in one of these

They have emergency batteries, and a mechanical brake if those fail, just like regular elevators.

How does this behave in the event of a power failure?

how well will credit cards and storage media survive being inside the linear engine "rotor" ?
[+] TD-Linux|8 years ago|reply
The linear motor is confined to the rails behind the cabin. It's basically a bigger version of the linear motors seen on some CNC equipment.

I'm curious to learn about the routing algorithms for this -- more precisely, how they differ from 1-d elevator scheduling routines.

Going horizontally and vertically in an elevator is like playing side scrolling games but this time you are inside the game! Very exciting!

5 times as expensive to install, and looking at all those moving parts probably 10 times as epensive to maintain.

That's only for the first version. It's not unlikely that they can compete by price in the future. First versions of a new technology are (nearly) always more expensive than the existing, mass produced product.

Elevators are a huge constraint in tall buildings, something like this could have a dramatic impact on overall building costs.
