Doors are some seriously ancient tech but they have this problem where they can only keep people out if they’re closed. This bizarre but clever take on the “revolving door” by a company called Barbecan, on the other hand, aims to get you inside, but simultaneously keep any ne’er-do-wells out. Specifically ne’er-do-wells with bombs and guns.
This system, which Barbecan calls the “Linear Revolving Door” works by encasing every entrant to a building within his or her own little private cell on the way in. While they’re in there, sensors check for guns or bombs or whatever bad news you might be able to detect, and if the results are positive, the linear revolving door can either trap the target in there, or reverse to spit him out. It helps to see what it would look like in action.
While it seems like the Linear Revolving Door could be effective, it’s also got none of the simplicity of traditional doors. And man would it suck if the mechanical doors that are designed to contain bombers and gunman break down and won’t open. And that’s to say nothing of expense. Still, a system like this could be pretty useful in particularly high risk areas. Don’t expect to see it any time soon though; Barbecan is just in the patenting stage of this one. But if crazy spurts of violence keep up, then you can imagine something like this is going to show up eventually. [Barbecan via Discovery]

very clever
BUT
i can imagine them breaking down a lot, they seem so complicated, that they cant be that reliable especially after 12 months in service
Problems with this system.
1. Mechanically complex, liable to break down regularly.
2. The moving walls would have to be thick/heavy if thing was meant to contain a bomb blast, thus any system would be put under considerable strain, again causing breakdowns.
3. there is a gap which allows the walls to pass, this means a gas based attack would not be contained.
4. the video shows each person taking about 10 seconds to pass through with about only 3 of those enclosed by the moving walls, can any system scan for bombs/guns/etc in this time and if so, where are they going to go as most of the lane walls will be required for the mechanism of the moving walls.
5. In the example shown you can just walk round the outside
What’s with the key logo?
Now, to be pedantic at 5-45am
1) Not if a decent company builds it.
2) Walls don’t need to be thick, if the ceiling is the weakest part of the ‘temporary’ box then the main force of any explosion would go up, taking path of least resistance. Also,if they were balanced properly weight shouldn’t be too much of an issue.
3) A slight negative pressure system could solve that.
4) Detectors would work generally in under 1 second and they could be in the floor.
5) Fair point but you have to hope they go through the security channel
I get the feeling a similar result could be achieved with a lot less moving parts… let me get my pencil.
Yes, it’s called a revolving door
highly over engineered
And you think this is a new door design?
Banks in Greece already use these doors, sans the gun detectors. Essentially, you are trapped in a reinforced glass enclosure with a door behind and a door in front. The door in front can only open when the door behind is locked. While inside the enclosure, security checks you are potentially a good customer and opens the door in front.
Treating everyone like a criminal that someone has to approve of to enter the branch is annoying to say the least.
No, you’re thinking of secure doors, which are used pretty much everywhere. The difference in this design is that you don’t have to stop – you continue walking while the door opens before you and closes behind you; hence the comparison to revolving doors.
Ah, thanks! I looked at the render and I thought the doors were opening and closing rather than revolving.
So the only leap here from the standard ‘air-lock’ type system is magical sensors that can detect bombs and guns in a few seconds.
Frankly this is over-complicating a non-issue.
Would be so easy to troll if the doors were made of glass…keep walking presuming door is going to open *THUD*
