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.

Sweet. My new Prius gets between 812448 RPH and 48 MPG. I think I've saved enough on gas to get one of these...
Futurama here we come!
Have you metaroderated recently?
the world's largest penis pump. Good grief, I can't believe I just said that.
Rick : I think Richard Harrelson has them.
Mr. Johnson : Get Richard in here NOW !
Zoooooooof - plop
... 204 Kg = ~450 lbs
I think I think, therefore I think I am.
There are only 96 people in the US that it can actually lift....
oops make that 74, McDonalds are doing an all you can eat special today.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
Laziness and status aside;
The real answer is for the Elderly and the disabled. IF you check out That Home Site you'll find a lot of interest in residential elevators. If it isn't feasible to buy a single level house, an elevator allows you full access to your entire abode.
In the future, I would want to not be isolated from my friends in the Space Station.

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.
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.

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!
Signature.
news flash:
elevators don't run on guinea pig droppings. All modern elevators (excepting perhaps the Space Elevator) run on ONLY electricty.
Did I miss something here?
The truth about Led Zep should never be told on
Simple physics. Your water pressure it between 20 and 60psi. (Anything higher will break hoses) City water is generally on the high end because cities have to reach the upper floors of houses on top of hills, and regulators are a lot each to install and maintain than pumps. Well water is often on the low end because you set it for what you need.
20 psi means that if you have a tube with a piston with one square inch of surface area, the piston will hold up 20lbs. A little math and you can find how big a piston you need to lift the weight (Not mass, we care about fighting gravity) you are concerned about. Now just place the piston in a tube long enough, and apply water. It will lift your elevator.
The hard part is making this without digging a hold DOWN 2 stories to place your tube in. There are many solutions to this, they are left as an exercise for the reader.
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?

Probably a better example is Aloha Airlines flight 243, which looked a whole shitload worse.

Only one fatality, which is kind of amazing if you look at the pictures (flight attendant blown out).

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.
