The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.

I was reading A Coffin for Dimitrios (great book), and found a character saying "send me a pneumatique when you get to Paris." And in fact, there was a series of pneumatic tubes to speed the mail in Paris for over 100 years. Thought it was cool. Here's the wiki as well.

Some of those systems are still around. For example, Roosevelt Island in NYC has a pneumatic trash collection system. Apparently it's the only part of NYC that doesn't have trash piling up on the streets/sidewalks all the time.

We have had those in parts of Sweden for a long time.

Apparently they were invented in Sweden in the 1960s

But most of Sweden doesn't have those and we never have trash bags or something on the streets.

New York almost had a pneumatic subway system, but the inventor tried to go around Boss Tweed. Big mistake.

Pneumatic transit and atmospheric rail were kinda a fad in the 1800s. Even if it had been built it would have mainly been an attraction rather than a mode of transport. They were never really able to hammer out the kinks with maintenance and safety.

Funnily enough an atmospheric rail incident on the Dalkey atmospheric railway was more than likely the first time a human sustained a land speed over 100mph.

The son of the owner accidentally loosed the break on a single carriage that was supposed to convey a whole train and accidentally shot himself off alone, covering about 2 miles of track in less than 75 sec. Which in the 1840's would have been like engaging a Victorian warp drive.

Oh yeah, the people mover is really cool. Always been a goal to actually ride it if I ever make it down to Brazil.

It's a little bit easier to make them work nowadays with modern materials, rubber is probably a little more pleasant of a sealing material to work with compared to the og bearskin and lard.

Though one of the benefits of the lard is that the og one always smelled like a fry up when in use.

In 1824, a man called Vallance took out a patent and built a short demonstration line; his system consisted of a 6-foot (1.8 m) diameter cast-iron tube with rails cast in to the lower part; the vehicle was the full size of the tube, and bear skin was used to seal the annular space.

Back in the days before vulcanized rubber and plastics if you wanted to make a somewhat air tight seal you had to soak an animal skin in fat. With the amount of pressure you need to move a train, you need a pretty big and durable animal skin.

A letter from The Central Bureaucracy.

"Attention, Hermes Conrad"

"You are about to receive a letter from The Central Bureaucracy."

My God!

It's from The Central Bureaucracy!

The technology is still in use today and new systems are built, e.g. for moving around kab samples in large hospitals or industrial sites. Pretty hard to email those.

This is so steampunk I love it

Whose the US asshole that sent a cat

In the early 1900s, you could send pretty much whatever could fit in a standard cylinder. Theatre tickets, bills, postcards, novels and cats (yes, this did happen in New York’s pneumatic post) all whizzed around underground and reached their recipient in just an hour.

Name and shame

[–] Demdaru@lemmy.world 1 points 2 days ago

Cat tax had a little different meaning back then...

Prague did until 2002

[–] SubArcticTundra@lemmy.ml 11 points 3 days ago

Prague still has one although it's not in use any more
