So... what is the benefit of having it go sideways? Is it to go along the length of a building as well as the height?<br><br>I just don't see the benefit of something like this. It seems like a hugely complicated solution to a problem that doesn't exist. What's the problem with elevators that only go up and down? I'd really like to know.,(reply>), yes, that's the point. Like a paternoster, which was mentioned in the video :O,(reply>), I guess it could be kinda like a train system where multiple cars would be able to run on the same line without having collisions. I guess that makes sense for massive buildings that have high elevator traffic.,(reply>), I think the horizontal moving idea is to allow the elevator car to go from one shaft to the other so that you can have multiple cars per shaft and ease congestion
