my uncle used to be a police officer, he had to sit at the station and do paperwork all day, and he had a gerbil that he "borrowed" from his co worker's cage, and when he got a message in the tube system wanting his gerbil back, my uncle put the gerbil and a note in the tube and sent him back, the gerbil arrived a little dazed and happy to be back with his owner, people called him Rocket
There were trains that had a piston going into a tube on the track. The tube had a slit on the top so it could fit the armature for the piston. The tube was then drained from air and the partial vacuum pulled the train forward. The slit in the pipe was sealed with leather and had to be oiled from time to time but random critters chewed it up. It was also impossible to make intersections with this system.
What seems missing here is why those early inventors wanted to send cars through tubes using air pressure. The only alternatives were cables, not yet in use for public transport, but used in mining operations and other industrial funicular mechanisms. The London Underground railways used steam engines and were very smoky, which the pneumatic tubes avoided. That smoke was reason for London's underground railways to not be copied in other cities for decades. Electric motors for trains were not yet perfected either. Air pumps for mining were, however, so that means of employment of a stationary above ground steam engine seemed the way to go. Cable car railways first in San Francisco and then copied in dozens of cities we've forgotten ever had them, were just a few years off, derived, again, from mining practices and some versions of elevators. The electric street railway development would be some 18 years away from practical commercial success. That made the underground railways a much more civilized means of transport. None of these old pneumatic tube technologies was even close to what the Hyperloop proposal envisions, as they all still need atmospheric pressure coming in behind the vehicle for propulsion, and have a very light vacuum ahead. Air molecular drag on the tube's inside surface is a problem even the Hyperloop will have to deal with, though to a very much lesser extent as it is such a very low pressure tube. The key to that system is found in its analogy to very high altitude flight, another regime where air breathing engines tend to fail us, and electric means of propulsion begin to look better so long as there is some air at low density to work with for some of its functions. For Hyperloop, having some air still left in the tube means not having to maintain a very high vacuum at great expense of energy cost and originally was considered useable for suspension of the car with air bearings, as that residual air did have to be diverted in some way around it. I feel that eventually a combination of air bearing (somewhat like the way that magnetic heads in disk drives "fly" and magnetic levitation control loops will emerge as the way those vehicles will be supported. There will always be a layer of attached air molecules however thin, near that tube wall and making use of it seems necessary and desireable.
One of the highlights of joining my mother on shopping trips to Montgomery Fair in downtown Montgomery in the 1950's was watching the sales clerks use pneumatic tubes to send and receive payment and receipts. I don't know if other cities had department stores that also used them. Thanks for the memory.
Canada Owns Yes. We had been there in 1951 and moved back in January 1954. We left in May 1961 when [coincidentally] Montgomery was still under martial law.
Dick Hunter One should never be too old to learn and I doubt I'm the oldest subscriber to this channel. BTW, I'm not a grandfather but thanks for thinking that. :-)
Ohhhhh no, I know what happens with this. First you rally the people to overthrow city hall with your rockin' tunes, then you install the pneumatic tubes, NEXT THING YA KNOW YOU'RE MUTUALLY POISONING EACH OTHER'S WINE AND WE'RE LEFT WITHOUT KINGS! I'VE HEARD THIS SONG BEFORE!
My parents installed a pneumatic elevator in their home. It only goes between two floors, but it works the same way as the old mail tubes do. You stand in an air-tight capsule. A fan sucks all the air out the top of the elevator, causing the air underneath the capsule to push it up. When you want to go down, vents open and gravity does all the work. The only downsides it has in my opinion are its size (it only holds one person comfortably, two people if they don't mind being cozy) and how loud the fans are when it's going up. You can't have a conversation when it's in use.
The video was pretty much this: "Pneumatic Tubes!!! YAY!!!" for the whole thing then right at the end, "But we're just gonna use magnetic and electric engines" Lol.
This is what me and my friends call a Brain Bang: I literally just 1 hour before this was posted watched the season 2 finale of LOST and they used pneumatic tubes to transfer notebooks from the Pearl Station to a landfill as part of the psychological experiment to test and see if the subjects would watch and document on everything the people in the Swan Station did.
I'm working on a draft of a novel. It has an alternate time line, and the protagonist helped implement a pneumatic train system that replaced domestic air travel in Europe, the US and parts of Asia. Wrote that section less than two week ago. So funny to find this in my feed now.
Those pneumatic tubes really do look exactly like the ones we use to transport samples at the hospital where I work, but the stations we have are a lot fancier =p
Brunel built an atmospheric railway before the earliest example you mentioned in the county of Devon in England. It didn't last long but when it did work it was said to be both smooth and near silent.
In the 1940's through 50's, many department stores did not have cash registers at check-out counters. You handwritten invoice and cash were sent by tube to a separate room, office, floor or building, where the math was checked, your copy of the receipt was marked paid and your correct change was returned by tube. All in just enough time to give the salesperson time to properly package your purchase and exchange pleasantries.
Cool vid Michael - They still use these in Kmart here in Australia for money collection from the till to the back office. It looked like magic when I was a kid.
in the UK many supermarkets have them to transport excess cash from the tills to a secure safe in the cash office for counting later. it's largely a more secure system as many people don't know about it and the tubes are hidden but there was one incident I read about where someone had knowledge of the systems would go into the disabled toilets remove the ceiling panels and lift themselves into the space above. they would then disconnect the pipes, catch the containers, release the money before sending the containers back down the system. if anyone checked the toilet they were empty and if anyone looked in the receiving area they would see a nice pile of containers bit it wasn't until the person left with visibly bulging trousers that they were able to catch them.
See, I would've thought the cheaper alternative (to building the horribly complicated tube networks) would be to have more of an operator system. Every desk/office has an send tube and a receive tube. You put your message in a canister, with the recipient's name on it somewhere, most likely a slip of paper in the canister, facing out. You hit send, and the canister goes off to a central receiving area, where a person takes the canister and puts it in the tube for the recipient, and off it goes. One set of tubes (in/out) per office, and far fewer points of failure. Still faster than a runner.
Surprised and disappointed that vacuum trash collection systems weren't included. Especially since they are still in use most notably Roosevelt Island in NY
They have one at the Co-Op in Beamish Museum. Actually, it might not be pneumatic, but it's similar. Little spherical cases that go along tubes/rails to different parts of the shop via a 'switchboard' room.
Bionicle incorporated the idea of a metropolis-spanning chute network into its story in 2004. There, the chutes weren't pneumatic, but instead were composed of some unknown fluid that was kept flowing by pumping stations. They were mostly used for high speed cargo transit, but some beings rode in them as well. Is a fluid filled chute system like that more feasible than a pneumatic one?
+Nathaniel Little You are describing a hydraulic system. Fluids (hydraulic), as opposed to gases (pneumatic), are incompressible and require some more complex machinery to make it work, plus filling tubes with liquid is more expensive.
They would need to have massive reservoirs of the fluid in order to help keep the system pressurized. Also if there was a leak in the car you were riding in you would probably drown or be crushed by the pressure before rescue could reach you. They would have to pump out vast quantities of liquid to reach a broken car. With air all that needs to be done is open up a vent, stop the car and let in enough air to last until help could arrive through an emergency tunnel.
I mean, we already communicate information via a series of tubes due to the inefficiency that would be caused if the primary transference medium were a truck, so using a similar system for more... material goods seems like a logical next step.
Hank Green I love this scishow here on youtube . Your show is one of the best and most educational stuff ive seen . But I also want to say I love your bother's ( John Green) work. Both of you the most intelligent people I admire. I love your science show because I am a huge science fan .and your brother for making by far the best books I have ever read . Both of you my most favorite people I have to admire. Thank you for making these videos. And also Thank your brother for making the best books I have ever read!!!
I think the best piece of media that depicts travel tubes the best is the game Satisfactory. Each tube has an entrance at each end consisting of a bladeless fan. Since it's a game it all just works but if i had to imagine how it would work IRL it'd be something like this You'd step onto a scale to tell the computer system your mass so it can adjust the airflow for your BMI. Then you step forward and get sucked into the tube and the computer begins tracking your progress through the tube using radio relays in each tube support. When you get close to the exit the fan there starts up sending an opposing air current at you slowing you down enough to exit safely. You'd probably still have to roll or something upon exiting though or turn around inside the tube to face feet first as you exit. The only problem i can see are sharp turns. Idk how you send a person through a tube and not have them splatter themselves all over the inside at the first sharp turn, so turns are going to have to be wide and gentle.
i'm referring to what people call #2. as is now it is sludgy and slows movement in the present sewage system, clogs the system, and raises pumping costs. what if people stored it on their property and then when these facilities were full emptied it into canisters in a pneumatic tube system which could deliver this human waste to plant to be burned for energy, converted to fertilize whatever. the average person produces four 5 gallon drums of #2 wet two drums dry per year. so #2 does not take much storage space per person/year so it could be stored on ones property for years. one could reline existing sewers to adapt them to serve as pneumatic transportation tubes.
The Hyperloop combines the idea of pneumatic tubes with free construction labor, right of way over land, and operation. His "quote" for the SF to LA system barely covers the cost of steel to make almost 400 miles of elevated tube.
one of the restaurants near my old school used to use this technology to send orders from the bar to the kitchen and it was so cool and the tube ran alonmg the ceiling and you could see the orders whoosh along
Pneumatic tubes also have to pump air behind the object. a vacuum will only get it so far/high before becoming ineffective. it's the same concept as sucking water through a straw: ten or so meters up and you'll need a pump.
at the Bottle depot when a giant bag was filled with bottles they would put it in a big tube and send it to the back of the store. I got to push the button once, it was cool.
+mike shaft Close but not quite. The chemicals in mint amplify and stimulate cold receptors in your tounge when binding to tastebuds, much like what happens with spicy food but opposite.
Simple economics. A pneumatic tube transport would be, like railroads and light rail, a system requiring a fixed infrastructure that's limited to traveling between specific points. That's great for highly-traveled routes, at least until circumstances change and that route isn't so popular or necessary anymore. The advantage of cars is primarily that they require limited infrastructure (well-built roads are nice, but not absolutely necessary) and allow you the freedom to go almost anywhere you want. The advantage of flying cars, if they ever come about, would be even less infrastructure requirements (basically just a place to take off and a place to land), and even more freedom of travel.
You should discuss the reasons that things don't scale well, the square - cube law, etc. Very likely, you will discover there some of the reasons pneumatic tubes have not successfully scaled up.
I always wondered how you'd land on your feet at the receiving station. Like getting into the tube you'd walk in but you'd land upside down at the other spot since the air pressure is at your feet.
I bit of irony a guy telling me tube transportation will never happen - as his image is transferred from their recording studio to my home in a You *Tube* video.
I know I could probably just go look this up, but... if the train doesn't use air pressure to accelerate, why a pneumatic tube? Is the benefit to lost air resistance great enough to justify building and running this tube? Or, does it use air pressure to come to a stop?
They have these pneumatic tubes in BJ's or was it Costco, all around their store. These always intrigued me when I was young and it looks like Elon Musk found them as well.
...am I the only one who thought of Kurzgesagt (probably not spelled right) when they saw the thumbnail? Kinda reminds me of his art style. And I mean, hey! He WAS the very first Sci-Show President of Space, after all. :) (and yes yes Futurama and OBEY, I mean the rounded cartoony solid-colour-shapes thing.)
+jcoronet2000 The shutter speed is far to fast, and/or the F-stop is too narrow, and/or the ISO is too low to pick up sufficient light from the stars. In order to expose the moon properly, ordinary, bright sunny day settings on the camera must be used. To expose the stars enough to see them, you would need a wider F-stop, slower shutter speed, and/or higher ISO, but these settings would greatly over expose the moon to the point where all contrast is lost, and all you'd see is a circle of white glare. Try it yourself. Take a snapshot of the moon with ISO 100 or 200, 1/125th to 1/250th of a second, at F11. Use a telephoto lens & tripod if you have one, then set the camera settings to "auto," swing the camera 180 degrees and take a picture. It will select the widest F-stop, a high ISO, and hold open the shutter for as long as "auto" allows. If light pollution is low enough, you should see some stars in that image, albeit motion blurred from Earth's rotation and the long exposure, and narrow angle if using zoom.
Nosirrbro It's got nothing to do with the camera's age, and everything to do with correctly exposing the film or CCD to the available light. You can't have it both ways. A brand new digital camera behaves the same way.

They have these pneumatic tubes in BJ's or was it Costco, all around their store. These always intrigued me when I was young and it looks like Elon Musk found them as well.
why when u take a picture with flash on a black square on your hand does it shock you
are the ones at the bank the same mechanism?
My local bank has a pneumatic tube system. When i was little they would send a lollipop in it along with my moms stuff.
Yeah. That's true. I sure wish those tubes are used for transportation and delivering things.
...am I the only one who thought of Kurzgesagt (probably not spelled right) when they saw the thumbnail? Kinda reminds me of his art style. And I mean, hey! He WAS the very first Sci-Show President of Space, after all. :)
(and yes yes Futurama and OBEY, I mean the rounded cartoony solid-colour-shapes thing.)
Isn't it that certain city in New York uses something like this to collect trash? I do not recall where I read it.
my parent's bank had a drive through with pneumatic tubes when I was a kid.
You guys should have used a clip from Futrama
Thought the thumbnail said 'Pubic Tubes' when I was scrolling through my subs lol
why aren't there stars in the moon photos?

The shutter speed is far to fast, and/or the F-stop is too narrow, and/or the ISO is too low to pick up sufficient light from the stars. In order to expose the moon properly, ordinary, bright sunny day settings on the camera must be used. To expose the stars enough to see them, you would need a wider F-stop, slower shutter speed, and/or higher ISO, but these settings would greatly over expose the moon to the point where all contrast is lost, and all you'd see is a circle of white glare.
Try it yourself. Take a snapshot of the moon with ISO 100 or 200, 1/125th to 1/250th of a second, at F11. Use a telephoto lens & tripod if you have one, then set the camera settings to "auto," swing the camera 180 degrees and take a picture. It will select the widest F-stop, a high ISO, and hold open the shutter for as long as "auto" allows. If light pollution is low enough, you should see some stars in that image, albeit motion blurred from Earth's rotation and the long exposure, and narrow angle if using zoom.
+balzonurchin Short answer: The moon's surface is too bright for old cameras to be able to clearly see it and the stars.
+balzonurchin that was an awesome well thought out response. thank you.
Nosirrbro It's got nothing to do with the camera's age, and everything to do with correctly exposing the film or CCD to the available light. You can't have it both ways. A brand new digital camera behaves the same way.
jcoronet2000 You're welcome.
Tell your writers that maglev has nothing to do with air resistance {2:53}
how do fiber optic cables work
Didn't MI6 essentially turn an Oil Pipeline into a sort of Pneumatic Tube in Living Daylights?
Do a video about pilotless planes
What about traffic jams IN Pneumatic Tubes?
What if the internet is actually a series of pneumatic tubes?
Please do an episode just on the hyper loop
Why not developing proper Pneumatic Tube System for package or grocery delivery over drones?.
Am I the only one that gets reminded by this of that one shuttle scene from the polar express?
Is this a re-upload? I have already seen this.
