I actually had the opportunity to fully design & fabricate a pneumatic tube capsule to deliver and distribute medical supplies, pharmaceuticals and even lab tests that would shoot from any zone in the hospital in under 60 seconds for one of the newest and most high tech hospital in my country. It was quite stressful working with million digit system, a blockage would have caused SERIOUSLY major issues, I was very nervous for that first test but am happy to say I nailed the dimensions on only the 2nd iteration and it made its maiden voyage across the hospital flying goods distributed by an automated robotic pharmacist. That memory will live with me forever, from CAD to Fab, I poured a metric butt tonne of elbow grease on it. Bonus fact: The first video with the red capsule is called a “Swiss Log”

As a kid I loved watching the Pneumatic tubes working in my local Tesco supermarket, the cashier would send whatever through it and it would be whisked away, strange how we didn’t really notice all the tubes and stations at each till disappearing, I guess smart devices and WiFi etc kinda took over in a far more efficient way

Banks aren’t looking to replace them anytime soon. They’re still installed at newly installed sites, although more and more often the person you’re talking to is in a central location and the local branch tellers are following directions for physical objects from them, rather than talking to the customer directly.

As an RN, tube systems have been part of my workplace from the start. They are just ideal for that application. Anecdotally, they seem pretty reliable too. I can count on one hand the number of times the tube system broke down at hospitals I've worked at, and regular maintenance isn't done all that often. Also...they result in a hilarious scene in the movie Tommy Boy.

Futurama theme was playing in my head the whole time.

It was not that long ago that many department stores used them before the days of electronic credit approval. If you wanted to purchase something with your store charge account, the sales clerk would send the paperwork to the credit office who would look up your account and either approve or decline the charge. Some stores also used them for cash purchases. The sales slip and your cash would be sent to the credit office. A few minutes later your receipt and your change would come back. Some banks and pharmacies are still using them for drive up service.

There is a bar in Milwaukee WI that uses a pneumatic tube to shake drinks. Sends your drink for a trip around the whole building with a bunch of twists and turns, and since the tube is clear you get to watch.

I used to work in a Tesco supermarket and we used pods to send cash from the checkouts to the cash office. You would take the notes out of the till, screw it into a capsule and a pneumatic tube would send it very fast. That way you didn’t have to walk through the store carrying cash, it was all sent through tubes and locked away.

In southern New England, my bank, and many others in the area, are hybrid, with ATMs against the building, and a pneumatic tube in the next lane. I've had the same bank account for over twenty-five years.

man, this made me remember the Tom Scott pneumatic tube video, it already feels like it's been too long without his videos

We use them all the time in the hospital. Just built a new scifi esq tower and it has a multi tube loader like a revolver.

i remember Costco used to have these to each cashier stations

Good production quality! I loved all the old photos. :) I've been curious about pneumatic tubes ever since I was a kid, but this is the first really concise and clear explanation I've heard of their advantages disadvantages and uses.

C1 Expresso in Christchurch NZ uses one to deliver small meals and chips to your table. I think it was pictured in a short bit towards the end. It’s in an old post office and repurposed the tube system. It’s able to be upkept as the local hospital has a new pneumatic tube system for the lab and blood.

Every bank drive thru still uses these

A really neat video, well presented. Still in use in hospitals in New Zealand, a great way to quickly deliver samples or paperwork between multi-storey buildings and requiring low maintenence costs. Nice to see a different technology highlight on this channel as opposed to the usual computer-centric content. Great job.

This was a great episode thankyou James

Parents have that pneumatic air elevator, it's loud but it was needed due to space constraints. It's pretty fun to use but there's a definite weight limit that thankfully it won't try to work if it's overloaded.

I previously worked at a movie theater and each box office had 1 of these for doing money order changes when more coins or lower denomination bills were needed. It helped managers from needing to walk downstairs to collect the larger bills, go back upstairs to the safe to exchange the currency, then walk back downstairs to give the exchanged money. Plus, from a security standpoint, it meant the box office doors didn't have to be opened and large amounts of money didn't have to repeatedly be walked through the lobby with guests around.

When I was studying, I did work experience at the local hospital, and they have three separate tube mail systems, all in use. Really interesting stuff, I even got to help service one of them.

Stores still have that in my hometown, as a way for cashiers to safely get checks and money to the back office frequently

hospital manager from north Italy here, we use pneumatic tube mail to quickly send samples to the labs that are located on floor -2 also blood bags where needed (usually E.R.)

Banks and Home Depot / Lowe's still use them in the garden dept to send things back and forth inside the buildings

I've actually seen them in the last decade at some grocery stores as a method by which cashiers will send batches of cash to the office rather than wait for a supervisor or manager to come by and pick it up by hand. Sometimes it's faster and easier that way.

This is the best tech quickie you've done in a long time, maybe ever What an absolute delight

I worked in a hospital that was built in the 1900s and slowly expanded. They had, on some wings, a pneumatic tube system to deliver lab samples (blood, tissue, whatever, usually blood). Actually, the ironic part is that the tubes ran to the pediatric wing, which was built in about 2003 or so. Before that, it was a parking lot that was partially covered by the floors above it. So those tubes were definitely put in place in 2003. The OLD system for lab delivery is a dumbwaiter, actually, and that was probably put in when the original hospital was built at the turn of the century. I had to run one such blood sample from pediatrics to the lab myself, however. We had this infant (couldn't be more than a year old) who we kept pricking their foot and sending the blood up. Twice we did this and twice the lab called down stating it had clotted too much. So, on the third run, which I was in there observing, the nurse passed it to me and told me to take it up by hand and keep gently rolling it.

I never knew that massive networks of these things to deliver parcels existed until recently. Also, the hospital I work for has a network inside the building that is used a lot for sending samples and small medications around the hospitals.

Tom Green had a video on this on his channel. He sent a camera through it recording the trip.

Montréal's Glenn hospital built after 2010 was fitted with such a system exactlt to carry samples to labs. Apparently ahs fancy routing based on some code on teach tube so it gets sent to the right lab. My local supermarket has such a system to send cash collected from cash registers to the office upstairs. where it goes into a safe.

In the early 2000s my local Costco had a system set up for sending messages to employees, i always found it fascinating to watch at a kid when it would go off, but it was hardly used by that point. I used to go to Costco probably once a week, and i think i only ever saw it go off like 5 times total.

I remember cashiers using the tubes at the Home Depot I worked at, instead of walking cash to the back room, it was SOOO much faster just to have the front manager zip it to the back room given it was basically a 5min walk from the main registers to the back room.

saw some in a hospital once, let nurses send samples to the lab. apparently always a surprise when you opened the capsules since there was a fairly high chance the thin glass walls of the blood collection tubes were prone to shattering mid transit so you always ran the risk of a dangerous bloody mess. they didn't use them.

So THAT'S what was going on about that fish canon meme !

We still have these systems in the aircraft hangar I work in. We use them for transporting smaller parts and gaskets between the warehouse and the hangar.

My Sainsbury's Supermarket has them since our shop has 2 floors (floor 2 is staff only) They've sadly been put out of use and replaced with tellermate boxes.

There's also the garbage eating goat in Spokane (and I'm sure several other places) that uses a tube as a fancy trash can. I also remember when Costco had a massive tube system running everywhere, namely from the vault to the casiers.

Ive seen them few years ago at a Tesco store, so still used today.

I have never thought about traveling in tubes… now I can’t stop… thanks james 😅

Costco used to have these systems for depositing cash out of the drawer. If a cashier showed as having too much cash in their drawer, they would pull the cash, count it and put it with a count slip in a canister and shoot it off to an office somewhere.

Coles Supermarkets in Australia still use this system for their staffed checkouts. These are not just legacy installations. They're installed in new built supermarkets as well.

Oohhh series on obscure infrastructure tech?? love this!

The main issue with larger pneumatic rail is the same issues you have with rail- NIMBYs, uneven and varying terrain, track maintenance, and hard corners. You can't just draw a straight line and every bend requires more overall pressurized force to keep it moving. The tiny tubes in your bank or building apply more than enough force than is needed to move a small object, whereas the amount of force needed to move a car or a cabload of people is way higher. And the getting in and out of the tube will take forever, unless you want your blood and eyes to boil. And any $$$ estimate some tech bro spouts about the cost of the setup is based in BS, as costs can vary so much and the obscene costs of rail projects are them being realistic and open ended towards things like "Oh, for 300 km of the route we were gonna put the rail is right on top of gravel sediment over a cave system that will erode and potentially sinkhole from all the weight we're putting on top of it."- all of which apply to large pneumatic tubes, which would weight more than two lines of steel rails on top of wood. I'd recommend watching "Well there's your Problem" podcast which covers the Pneumatic Rail (and I even saw it as a precursor to Hyperloop) and they recently did a episode on Hyperloop itself breaking down why the tech fails in both concept, mechanics, and engineering to the point a Bus line would be cheaper and move more people even if the hyperloop was transporting 5 people at a time at supersonic speeds.

I'm an IT technician in a hospital here in Italy. The pneumatic tubes are much more interesting than our entire network. And sometimes even more reliable. 😅

They are still used in some UK supermarkets. The are used to move cash from the tills to the cash office.

A lot of supermarkets had them here in Germany where things like cash and receipts could be sent to and from the register without someone having to run around the often huge supermarket.

Dude that hat is so awesome. I will def. come back for the next episode. You go bro!

I remember seeing them at some supermarkets here in Europe when I was younger. For fast transfers of large amounts of cash from the registers without leaving seats on busy days I guess.

Loved it! Though bring Anthony I miss this dude, he explains amazingly!

Need more of this moderator!!!!!! And awesome info!

First time I saw the system was in Amsterdam. It was bieng used to transfer gems from one desk to another throughout the building. Was 12 or 13 and really amazed ❤

I recently came across a pneumatic tube system in a relatively new convenience store (Centra in Killinarden, Tallaght for any Irish people watching!). If you order some takeaway food, it's put in the tube and sent back to the checkout. It's a high crime area so I presume it's being done as a security measure.

I imagine a good use case for pneumatic tubes would be in security at an airport. It would be a great service to be able to check in items you are not allowed to have in the cabin like pocket knives, nail clipeprs toothpaste and other items banned. Send it via pneumatic tubes to lugage and have it shipped as checked luggage.

The reason pneumatic tubes actually counts as a "secure storage" is because you can have parts of the system pressurized/vacuumized at all times, and then have it connected to a pressure monitor. The system can by the pressure monitors know the "integrity" of the system at all times, and raise a alarm and shut down the system if any tampering occurs, and require a service technician to reset the system with his code. This in contrast to a mechanical conveyor system, where a culprit could intercept a delivery of pot or similiar and thus doesn't fulfill the requirement of "secure storage" unless all rooms where transport occurs, are alarmed and guarded. The good thing with pressure monitors, is also that the pump system can vary the pressure randomly, effectively "sending a code", and then verify the same "pressure code" is received at the other end. If someone tampers with the piping and for example tries connecting a external pump or vacuum cleaner or something to the system in a attempt to cheat the pressure monitoring system and being able to intercept things, then the "pressure code" will not match what the other end sends, thus the system can know tampering has happened. The fact is that these pressure monitors can be so sensitive that if a pipe section has been serviced and replaced, then the pressure monitor system has to be recalibrated for it to not trip, just because the volume of the pipe has slightly changed due to the servicing, which is "visible" to the pressure monitors. In addition, its also possible to identify capsules with for example RFID, and have RFID coils at different locations in the pipe, timing the exact time it takes for a capsule to reach certain points. If this differs too much from the expected time, a tamper alarm could be raised too. This is why pipe transport can be classified to the same security standards as the secure storage locations itself. Think like a supervisored alarm cable (with end of line resistors) - but with physical transport. This is why banks like the system. However, the problem with, what you said, shoving bed frames and foreign objects into the pipes, can be largely solved in two ways: Either make the public points receive-only in single-use capsules or make the pipe system completely sealed, meaning the capsules are not taken out, instead a door is opened on the capsule and the objects put into. If you want to make such a system very safe against foreign objects, you could have that the door on the capsule is spring loaded and open inwards. Then you put your thing into the capsule. When you are done, the capsule is lifted by a solenoid, from a pressure releasing valve, then the section where the capsule is, is simply pressurized. This causes the inside of the capsule to pressurize, effectively locking the door on the capsule, while this can be monitored by a RFID pressure sensor, verifying the door is securely locked and there is no leaks. Then its sent to the destination, where the capsule now hits the pressure-releasing valve, which will now release the pressure inside the capsule, which then allows the capsule door to be opened. This would completely eliminate foreign objects in the piping system. This doesn't however solve the problem with human transport, but it can be solved in a similiar way with interlocked doors on the pipe and the "capsule" inside (but without the pressure lock, a pressure lock is just needed for a small capsule where you don't have space for complicated locking mechanisms), preventing any capsule release unless both doors are securely locked. Still the problem with debris between the outer and inner door, which isn't a big deal in a object transport system, as it won't hurt its performance as much, so a human transport would need some kind of vacuum cleaner that starts when both doors have closed and locked, which cleans the area between the doors, before capsule is released.

I remember the checkout girls at my local supermarket cashing up in the middle of the day, rolling a chunk of money and putting it in a dispatch cylinder, then popping it into a phenumatic transport

Imagine the heist movie where somebody diverts the tube at a major bank or something.

i work as an IT in a hospital. we use such a system to transport bags of probes (blood etc) from stations to the lab and back. quite fascinating to see something like this in person.

Quite honestly I have to wonder why point-to-point parcel isn't a thing by tubes. You wouldn't need a food courier or mail/parcel courier, and those services are perpetually getting more expensive and unreasonable to use. I envision it would only work well in high rises though. Where everything you need in your unit (food, clothing/laundry,trash/recycling collection, etc) could just have a tube capsule with several NFC id's on them. So the blue-white capsule is for recycling, the white-black capsule is for laundry, the red-green striped tube is for food, the solid-green capsule for trash. Stick the capsule in the tube, the basement sucks it down, reads the id and then does whatever it needs to do with it, then sends the capsule back up empty. Likewise if you get a parcel or food couriered, they simply come to the building with the capsule and just stick it in the tube in the guest parking. The basement computer checks who it's for and sends it to them, and then when they got it, it sends the empty capsule back to the courier. It could work, I just don't see it ever being cost effective except for some really tall buildings (eg ones with more than 10 floors) even the 30 floor build I live in, the amount of time it takes uber-eats, amazon or purlator to get to my floor can be a good 10 minutes.

Some larger stores here in Finland use pneumatic systems to safely transport cash between the offices and cash registers. I think it's a legitimate safety benefit for the workers to not have to keep excess cash accumulated through the day in the register or carry it in the middle of a busy hypermarket in person.

In industrial environments, these pneumatic conveying systems are used for all sorts of things. Often you don't even need a case. Systems like this can bulk transport coffee beans, plastic pellets, sand, grains, seeds, and so on. And there's always need to transport such things from one container to another, or to a top-loading train car.

I work in aerospace, these ones are amazing for large company grounds and complexes

We used to have one of these that put experiments into our nuclear reactor. The same reactor still has functioning message tubes for the different locations--even if the reactor doesn't work anymore.

The fish cannon just tickled me big time, love it!

My old job had that system to transport Invoices and other paperwork across Warehouses Offices and different Buildings alltogether. It was always a Highlight to me when i got to send away a so called "Bomb". But always scary when one arrives due to the still highspeed of the Bomb

I remember going and visiting my mom while she was working at the local hospital. You could put the tube in and punch in the destination, so when she was on break we would send mail to ourselves. 😊

Some pharmacies here (Finland) deliver the products from their storage to the desk with pneumatic tubes. They are not relics or legacy by any means for this purpose (as you can't digitize drugs).

The hospital near me has one of this systems for transporting medication, blood samples, and things like that.

The hospital near my house still use it for samples and medicine transfer.

I work at a hospital, we use these a lot. User error is a common thing. I remember how a few times the canister got messy cuz someone didn't seal a sample properly inside

My local home depot (built in 2012) is still using these same tubes to send money from cash registers to bookkeeping

haha "whoops, bankrupt" xDD ohhhhhhh, boy. omg the salmon cannon! i remember that day. it was a good day. I remember seeing these tubes at every supermarket checkout in the UK. Almost never saw them used. I wonder if some still remain. ...Put me in the picture with "these men are all dead".

Very much still used in the UK larger supermarkets. To take money and time sheets to the back office.

I would like to make-a the deposit. "NOT YOU AGAIN!" *frantically pours marinara sauce into tube*

I work as an optician and we still have one of those for connection of our store and the workshop upstairs. My chef once said we need to take care of it, as the company that build it is no longer there and we might not be able to replace it, if it ever breaks.

A lot of people get them installed in homes now too to transport laundry down to the laundry room as well.

This was genuinely fascinating.

I used to work at a movie theater that still had one of these. I used it a few times

We used to have these at the supermarket I worked at in high school for sending excess cash from the register to the counting room. This was less than 20 years ago.

There’s a company that installs them in your house as a modern laundry chute, it’s pretty cool stuff!

Today they are usually used (at least in canada) to send cash away from registers, so if the place get robbed the will only get a few hours of cash which isn't much in Canada. They can be seen publicly in "Reno Depot" for example.

The reason why we don't travel in tubes is simple and can can be explained in one sentence. *Clears throat...* "Because it REALLY sucks."

Meanwhile, in the board room- Jerry: I've got this GREAT idea guys! Boss: Okay, Jerry! Let's hear it! Jerry: Well, first off, let's just say that my idea really sucks! Boss: I'm going to have to let you go, Jerry.

There are some in the US that are used on pharmaceutical locations like Walgreens, especially if they handle 2 lanes.

Very common here in Grece in large supermarkets... It's a safe way for cashiers to send money to a secure office so they don't keep too much at their station.

Hospitals use these a lot to transport blood samples to the labs for testing, particularly emergeny departments

A streamlined vehicle traveling through stationary air has its own surface area exposed to the wind of its passage. A blunt vehicle traveling through a tube feels no wind, but the entire length of tube from end to end must have the full wind flowing over the huge internal surface area of the tube. This causes immense friction losses and makes flow-driven tubes impractical.
