So many negative comments for a Saturday. This is a marvel of engineering and deserves a celebration. Humbled by our ability to re-invent more and more. Well done to all involved.

#12I hate to be so cynical, but for how often the TK elevator in our building is out of service (these things have been around for 100 years and still break down more than a Fiat), I don't have the confidence necessary to step foot in this thing.

#13looks expensive to build, purchase and maintain. not sure there's anything "revolutionary" here.
If the rails are solid state using for example magnetic levitation, I can see this being much cheaper to maintain.

#14My dad was is an elevator repair man, has been for the last 33 years. When I asked him what he thought about his job, he said "just like any other, it has its ups and downs"
But after seeing this, now we are going back and forth on the future of the industry!

#15"World's first 3D people mover" might be a more appropriate --- and enticing --- title, because "rope-free" can also refer to hydraulic elevators (which have been around for over a century.)
As far as I can see, the design only allows 2D movement. If you wanted the lift to move toward or away from the camera, you would need either some kind of 2nd attachment point on a different side.
why couldn't a horizontal segment have a curve to change the Z axis by whatever angle you wanted to get to.
Also, they could have a completely circular horizontal segment to move people through an upper level of a round building - like a stadium...

Time out of service has much more to do with who services them.

Note that a TK elevator doesn't mean it's actually still maintained by TK. For example in my previous building there was an Otis elevator but at some point the maintenance stickers on it became TK's, probably because they offered a cheaper maintenance contract.
TLDR: the manufacturer can't do much about the owner not maintaining their product properly.

#18Impressive video. The implementation looks complicated and might have reliability issues.
Wonder what tech they use for traction while moving vertically.

#19Off-topic, who is the narrator? I think I've heard him on another German "corporate presentation" video, and I can hear a slight German accent... And back on-topic, googling to find the details instead of just a flashy video, here's Tom Scott on MULTI: https://www.youtube.com/watch?v=kdTsbFS4xmI
He sounds somewhat similar to the kurzgesagt voice-over artist.
