(Mainichi Daily News)   World's first "maglev" elevator should ready by 2008. Scientists pointed out the biggest problem in making such a device was how they got the doors to make that cool "shhh-ing" when opening and closing   (mdn.mainichi-msn.co.jp) divider line 56

What's the point of using maglev if you don't make it faster than a conventional elevator? What a waste.

The famous Star Trek "door sound" was made from a combination of an air compressor and a shoe that was 'squeaked' across a floor.

I'm thinking the bigger issue just might be the FRICKIN' BACKUP POWER SYSTEM should the FRICKIN' POWER GO OUT!

What do you know, it's not only more comfortable but quieter as well when compared to conventional elevators...I wonder if that has to do with it traveling at 1/3 the speed?

JWMthree: What's the point of using maglev if you don't make it faster than a conventional elevator? What a waste.

Why? Height is probably the biggest reason. Conventional elevators are limited by cable lengths.

Pontentially less maintenance because, except for the car, no moving parts.

Might be easier to put multiple cars in one shaft, if you'd want to do that.

Absalom: I'm thinking the bigger issue just might be the FRICKIN' BACKUP POWER SYSTEM should the FRICKIN' POWER GO OUT!

It's trivial to implement a braking system that uses induction to slow the car. It can't stop it entirely, but it could almost certainly slow it to a perfectly non-lethal speed. Such brakes are already in common use in amusement parks, and are virtually failsafe.

Ouch. I read the article, got to the bottom, and my eye caught the word "plunge" in one of the links about stocks falling, and I got the willies.

Actually if they are using the supercooled superconductors for levitation, then levitation can be maintained even with a total power loss. Levitation is produced by superconducting magnets, which will work as long as they stay cold enough. Electricity is normally used for a cooling system, but the elevator could probably just return to the ground floor or apply a brake before the magnets warm up.

Conventional elevators could be faster (IIRC) but there is a limit to the vertical acceleration a person can sustain. The quieter/more comfortable aspects are the main advantage, as well as what evaned has pointed out.

No doubt they will get faster; this is the first one.

And I forgot to mention about the induction brakes: if you constrain yourself by saying that the elevator car has permanent magnets, I can't think of a design where you don't get at least some induction braking for free.

Levitation is caused by the fork lift behind the curtain.

My office builing is 60 some off stories. To get to my floor i take an express elevator that bypasses the first 30 of them. They really can't make one go much faster than that thing does without it being uncomfortable for many people. Hell people complain about their ears popping as is. (probably blows through the 30 floors in under 10 seconds, although I never timed it)

As mentioned above, the benefit to this probably has to due with maintence. Less (no?) moving parts in a setup like this, nothing to really generate friction to wear out, etc. You probably don't notice it in your office because typically there are a bunch of elevators and work can be done afterhours and whatnot, but when you live in a building with an elevator, you will find the damn things break all the friggin time. 8 floors really friggin sucks when you have groceries.

Modern traction elevator motors are already gearless which means the only thing holding you up is magnatism. KONE Elevators created the first commercially viable axial-synchronous motor for elevators. It has perminant magnets on a rotating sheave and an electromagnet on the fixed side. The electromagnet polarity shifts around the axel causing the sheave to move as the like poles repel/attract. They have brakes that are pulled in via solenoids so if the electricity cuts off the solenoids release and the spring operates the brake. There are also brakes on the car that activate if it goes too fast and a plunger at the bottom to slow you down too.

A spinoff of the Space Elevator project is likely to be ordinary elevators that are very fast and safe.

That is, much of the Space Elevator is funded by technology spinoffs they will invent en route to the SE itself.

Imagine if you had just an ordinary cable a few millimeters thick that could perform the same task as a steel cable an inch or two in diameter. The weight and cost savings will be enormous. Ordinary elevators would become much faster, their motor not having to lift the steel cable, too.

They might be missing the boat with maglev. Instead of using it to propel the elevator, its best use might be in making a smooth ride and smoothly braking the elevator when it reaches its destination.

Skyscrapers have elevators that go in excess of 15-20 mph. You can certainly get normal elevators to go faster... but they're likely old and/or too darned expensive to replace.
