[ExI] RES: RES: UltraRope could make kilometer-high elevators possible

[Henrique Moraes Machado]

Not at all. I don't think I've got the resources to do a cost analysis
(neither know how to). 
I was just brainstorming and MagLev was just one idea. For instance, why do
elevators have to have a shaft? They could as well spiral around the
building. They only need energy to go up and could be lifted by some kind of
crank like rollercoasters and go down by gravity alone, with air dampening
or using Lenz current (or some other method) to slow it down. 
Elevator companies lack imagination. J

I read this a few days ago and got me thinking. Why do elevators have to use
cables at all? Can't they build a maglev elevator or something? Not talking
about the space elevator obviously, but building elevators.
 
One significant obstacle to a maglev building elevator would be the safety
issues solved by the Otis elevator brake. Perhaps it's not such a stretch to
solve the issue, but then is it really a maglev elevator?
 
I do think you've got a really good point here, and I suspect the issue
probably revolves around the expense of building such a beastie. Have you
done a cost analysis Henrique?
