Vacuum-Controlled Elevator Developed
Aenox writes "Vacuum Elevators of Florida have released a one-man elevator system that easily slots into buildings. It has gone on sale in the U.S. for around $20,000 and uses only electricity to power vaccum-inducing suction turbines that can lift 204Kg several floors up. They claim it provides a smooth ride but from the video it looks like it could use some oil."
But O'Connor adds that a series of mechanical breaks will activate should there be a sudden loss of pressure, to prevent the capsule falling.
I'm glad to see this because this was my first thought on watching the video. I can imagine all sorts of overly dramatic Hollywood type scenarios...... Cut the power to the building.....drama ensues. Or, a couple of well placed bullets into the side of the plexiglas causing a sudden implosion and dramatic falling of the lift. Also, one would want to ensure there are no leaks from the capsule to the inside of the lift tube. That sort of thing could play havoc on your eardrums, sinuses and eustachian tubes. Ask anyone who has been in a plane when they open a cargo door before completely equalizing the pressure in the cabin...... Wow, talk about uncomfortable.

Does NewScientist.com have editors?
Call me picky, but if you're doing a professional publication, there are some standards you ought to uphold.
But O'Connor adds that a series of mechanical breaks will activate should there be a sudden loss of pressure, to prevent the capsule falling.
Well. this certainly doesn't sound promising. I would think that in the event of a sudden loss of pressure, the elevator would 'break' quite satisfactorily on its own, without the need for additional mechanical help.
The elevator costs between $20,000 and £22,000.
That's actually quite a large price range, once you figure out the exchange rate.
Clearly someone over at NewScientist.com is asleep at the switch. The sad fact is that this is nothing new....even sadder is the fact that this sort of thing is now acceptable, even in professional publications.

It seems there's no shield between the occupant and the sides of the stationary tube.
If that is true there could be risks if stuff (like clothing) gets caught at the wrong places... Not very high I suppose - it's just like using an escalator - if you careless/stupid enough to get something caught you better hope it rips rather than you rip...
All the pneumatic pumps I've used are maddeningly noisy. I hope this one's an exception.

The primary market for residential elevators is for the elderly and wheelchair bound. From what I can see, this elevator isn't stable or safe enough for a frail elderly person, and it isn't large enough to fit a wheelchair or scooter.
So the only market for this thing is going to be for rich people who'd rather blow money on a toy than take the stairs. While I'm sure there's a market for that, it's not going to be a big one.
There is nothing so pathetic as seeing a beautiful young theory roughed up by a tough gang of facts.

I reckon the intent putting classical music in the video is to distract customers of the sound of the pumps? Found it nowhere on their page.

Just because you can mod me down, doesn't mean you're right. Shoes for industry!
for my Grandmother whose mobility was starting to wane. It was powered by water pressure (from a regular tap (faucet)) on the way up with a valve controlling the water release for a smooth ride down. I have always wondered how it was able to provide enough lift (it still puzzles me today). Regular water pressure? I must take my camera next time I venture there. He's a metal-worker by trade (specifically I'm not sure) so the quality of the structure is first class.
SOmething's really odd here -- the people who would most need this are folks who are in wheelchairs. And yet the tube is clearly too narrow for any sort of handicapped person. Why invent a freaking elevator for the people who don't need one? Do they have a handicapped version? Looking at the size of the capsule, I doubt a person with arm braces could fit in there. It seems really cruel to make an easy-to-install elevator that won't fit the people who need it.
They claim it provides a smooth ride but from the video it looks like it could use some oil
Hmm I guess this elevator really sucks then...

Aha, so there's prior art? Then I guess we won't see them succeed at patenting it, if they try.
I've heard that many an inventor has been foiled by prior art in fantasy movies. I move that we declare fantasy movies illegal, in order to protect intellectual property. Fantasy/scifi movies are like pirating the future!

Did I miss something here?
The truth about Led Zep should never be told on
What happens if you open the door when the elevator is not on that floor? It looks like it would open right up. If that is the case, what would happen if you opened the door, and by accident dropped something into the tube? Would it get sucked up by the fan and blow out the system? Do the doors lock when the capsule isn't on that floor? (sorry for two posts in two minutes; my friend and I just got to discussing this sweet contraption)

He stole my story I tried to post yesterday, and I had a better tag line too:
2005-05-06 18:01:29 Elevator from Futurama! (Hardware,Technology) (rejected)
and a better description.
This elevator comes in 2 modes: 2 floor mode and a 3 floor mode. It is easy to install, you only need to make a round hole in the floor/ceiling and put the round tube-shaft through it. It works by pumping the air out of the tube from the top (a pump generates 87dBA of noise,) and since the pressure underneath the cabin stays the same, the cabin goes up.
Safety is guaranteed by a mechanical lock that stops the cabin dead in case if pressure under the cabin becomes weaker than the pressure from above. On the other hand if electricity cut off from the pump, the cabin wouldn't get stuck between the floors, it would slide down slowly due to slow pressure venting.
There is a clever cabin ventilation scheme...
anyway, this thing looks a lot like the mode of transportation used in Futurama and my last sentence was:
Now I wish someone came up with an american favorite Suicide Booth, then my day would be complete.

Bullets won't be much a problem. The glass in this thing is the same thing they make bullet proof glass out of. Maybe not as thick, but it should still be enough. Even if not, this stuff won't shatter like glass, so the leak won't be as sudden.

I think this is a pretty neat idea, but how much would a regular elevator install cost. That could actually take multiple people and lots of stuff..

Tristan, you're not going to get any usable help here, unless you give us usable information. Are you getting an error message of some sort?
Initially, I had trouble as well. I was getting a page that said "SERVICE UNAVAILABLE". It was not a problem on my machine, however. There were so many people trying to see the same video that the server could not keep up (Google for "slashdot effect"). I tried the mirror link that was posted elsewhere, and it worked fine. I am running Firefox on a Fedora core 3 machine and I am using mplayer to view the file. It works, no problems.

I use the stairs. I even use the stairs when a hotel puts me on the 8Th floor.[1]
This is for some friends and relatives who can't take stairs. Have you seen what MS does to people? Ever see a 40 year old who cannot walk? It isn't pretty. Then there are general old people who can walk, but need help on stairs. I want an elevator in my house for them. Too bad this model isn't big enough for a wheelchair.
[1]If I can find ones that you can enter without setting off the fire alarm anyway. Back in school it was not an excused absence from your finals if you were trapped in an elevator for the test, as some of my fellow students discovered (rated capacity was 12 people, and there were 15. This was a 12 dorm). No I no longer take an elevator that is close to full.
...like it would really suck.
This is a great physics problem. What maximum pressure (in atm) must the vacuum chamber above have in order to lift a 200-lb man and a 200-lb elevator capsule? Assume 1 atm below, and a tube with 1 m diameter. Let's compare answers.
...and uses only electricity to power vaccum inducing suction turbines
Not to be picky with regard to the article summary, but what the hell else did they think it was going to be powered with? Hamster wheels?
Imagine that! It uses only electricity! Our former model tried the hamster wheel approach, connected directly to the suction turbines. But this one is new and improved!
Sheesh...
He who has no
While still a clever design, this is a giant step backwards because it does not provide positive position control. Vacumn just provides a force, not a means of controlling position. From the video it looked like he had to tweak the elevator position before he could open the door.
As for opening the door above the car while it's running, remember there is a vacumn holding the door shut with at least a few hundred lbf.
Nice troll... now go out and catch some fresh air :)
The AACS key is NOT 0xF606EEFD628B1CA427BEA93A9CA9773F
if you watched the video you would see this isnt marketed towards the handicapped but to rich/dumb office execs, if you look at the tube you would of seen there isnt enough room to open a newspaper never mind walkers/wheelchairs
but then again this is slashdot where people comment first before thinking about what they are actually saying (much like the current USA president (perhaps its a culture thing))
It was enough to slashdot the server. Welcome to the world of facts, Ta Mere...

Thanks for that link. There are more videos there, downloads are fast, and the videos seem smoother than the one linked from the story.
Two- or three-floor versions are currently available, and the company is now developing a four-floor system and another that can accommodate a wheelchair.
Wheelchair support coming in a future patch!
Why do they use a vacuum instead of pressure? I can imagine that due to the round shape it is better to have a higher outside pressure instead of a low one (to distribute the force), but this should not be a technological problem (use stronger glass, reinforce...). Creating a vacuum sounds more difficult to me than creating pressure. On top of this, pressure can lift any load, while vacuum is restricted to the atmospheric pressure times the surface area of the floor.
It would seem to me that there's a limit to the amount of vacuum you can get above an elevator, but no limit in the pressure you could generate below it. I mean, if the elevator is 4 feet across, then the absolute theoretical limit of wieght that could be pulled up by suction (assuming standard sea-level pressure) would be...
interesting. Google can't parse:
(pi * ((inches in 1 foot * 2)^2) * psi in 1 atm) / lbs in 1 ton
but substituting in values, you get:
(pi * ((12 * 2)^2) * 14.6959488) / 2000 = 13.2965812
OK. I guess that's not so very strange after all. In a 4 foot wide elevator, you can lift 13 tons with a hard vacuum above it. Damn. 15psi sure does add up quick.
Pound! Bang! Bin! Bash! is this a shell script or a Batman comic?
I wonder what happends if that elevator stucks for some reason with a person inside it. Will he have anough air to breath while waiting for somebody to let him out? And wouldn't it be easier to build a similar regular elevator (without counterweight if dimension of that elevator must remain small), but with more common technology and without need of air tightneds..

Look 14 seconds into the film - is that a marble bust in the middle of the picture back against the wall - and the head is tilted back? If this doesn't have Batman written all over it, I don't know what does. All they need now is to put a pole in the middle so you can slide down.

This company is from florida. As someone else stated before, a piston elevator would need a hole as deep as the elevator is high. When you are in florida, if you dig down, water comes out. This elevator is good for homes that cant dig for a pneumatic piston and cant have a huge pulley system to pull the elevator. They'll probably use it for two floor hotel suites and things like that.
by how slow this thing is? The one at the bank really rips along, and for the money, I want a FUN ride!
man, I feel like mold.
I hope that the elevator is engineered better than their web server.
They're missing out on a lot of customers right now that are trying to research these things.
Don't think that a small group of dedicated individuals can't change the world. It's the only thing that ever has.
I was at a mall once where a girl got a foot mangled. It's why the things have emergency stop buttons.
Basically, there are two major points of failure: between the side of each stair and the escalator wall, and more likely, at the end of the escalator where the stair slides under the floor.
It's possible for loose clothing (low hanging pant, shoe lace, etc) to get caught between the stair and housing, and pull in a limb. Another problem is small children who sit on th escalator and get things like drawstrings caught.
But don't take my word on it, how about the Consumer Product Safety Commission?

It seems like a really pointless bit of technology - i can understand that its main use is for places where you don't want to dig a shaft for a pneumatic lift and maybe don't have room for a motor on top and a counter weight, but this is just over the top! Ok so it has emergency breaks should the pressure fail, but cable lifts have always had very simple, very reliable locking mechanisms. If the door on an upper level is opened or its seal fails for some reason, the lift won't work. Seals like that don't last for ever. If the glass/plastic is broken for some reason you'll get a possibly hazardous implosion and if the roof of the cabin was to fail the person inside would suffer from explosive decompression. A simple motor and pulley is surely much more reliable and easier to maintain than a full scale vacume pump system? and as for control - well it didnt exactly look precise from that video, im not sure why the sucked-out air from the top was not fed into the bottom to make it a little more stable (it says the bottom is at atmospheric pressure, i guess it would mean building the tube to withstand low and high pressure. Making this lift any bigger (for more than 2 people) would seem like a big challenge, as would extending its range, so you have to ask the question: why would a lift company invest in a technology that was inherently restricted to a few floors and a couple of people (and barely a wheelchair)?? Why not take a cable lift and try and fit the whole package into something similar to this - they could keep the tube and have a fully circular counter-weight, which would look pretty cool. This technology doesn't seem to make sense unless you have a discount on turbines and plastic tubing, and clients who want to send non-wheelchair bound people up 2 floors one at a time...

I agree with you, in this particular case. Although no one particularly cares about grammatical rules, which really are flexible, the article is just wrong. Breaks are very different from brakes, and dollars are not pounds. This isn't a small spelling/grammar issue, it's factual inaccuracy.

...you just stepped in and it sucked you up a floor, rather than having to stand in a casule. That would be impossible, but way cooler.
Now the question is, who had the cajones to fly the plane from Hawaii to Mojave? Safely landing the plane after the roof peeled off is one thing. It's quite another to get into an airplane whose fuselage has partially peeled away and fly it several thousand miles. Especially if most of the flight is over water. That took big brass ones in my book.
The article the grandparent references states that the plane was dismantled in Hawaii. Looking at the plane on the Mojave tarmac from about 1/2 a mile away, the plane looked intact - wings, fuselage etc. Perhaps someone who has seen the plane closer than that could comment.
So much for the top exit door. Pfffffffffffffoooomp!

This elevator looks too small to accomodate a wheel chair. So, the only people who can use it are those who don't need it.
For the price of this elevator, you could install a full size elevator. I have used one elevator that I am told cost $30,000 to install and that included boring a vertical shaft and horizontal tunnel through the side of a mountain. For considerably less cost, you could build a single person elevator.
They claim that the elevator saves energy because it uses gravity on the descent. What they don't tell you is that it uses more than twice as much energy on the way up as a similarly sized elevator using the conventional counterweight design. A counterweight elevator only has to raise the weight of the occupants since the weight of the car is balanced out by the counterweight. Indeed, the counterweight might be as much as the weight of the car plus maximum occupancy load, in which case the elevator needs to use power to lower the car and only needs to release the brakes and overcome friction to raise. Futher, the inefficency of the vacuum pump could be considerable.
A hydraulic elevator of the size shown could also have been constructed using a cable or chain over a piston that travels half the distance as the elevator car (same design as used on many forklifts). This would be simpler, more reliable, and avoid the dynamic load problem described below. The design could be as compact and "portable" as the vacuum elevator.
Vacuum induced lift is a constant force rather than constant displacement technology. This is a very serious problem. When you step off the car, you can expect it to spring upwards. They probably hide this serious problem by making an elevator that can only serve two floors. At the top floor, you drive into a hard stop. At the bottom floor, you do not allow the door to open until the vacuum cylinder is fully vented. On a multifloor design, you could have a mechanical lock that engages before the door opens but then when the lock released there would be a sudden jolt if the passenger was not the same weight as the previous passenger (if any).
The large seals required and the fact that they must operate past doorways (unlike a hydraulic lift) will lead to significant maintenence problems.
This product looks to be pure gimmick. The technology used and other aspects of the design are totally inappropriate to the task.

How did you arrive at 32 feet? I believe you're confusing this with sucking up a column water (ie a water pump at the top of the piping). Scroll up a few posts and you'll see someone posted the relavent equations to calculate max lift which is really just pressure differential x area.
This is old news. My checks and deposit slips use this same sort of elevator all the time. Just be sure to ask the homeowner before sending coin.
