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.

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
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.
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.
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.
