I don't mean BETTER. That's a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That's just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

Pneumatic tubes were way, way cooler than email.

Of course, you could only use them to send a message to someone in the same office building, so the comparison isn’t perfect… but you know what I mean.

I'm not crazy old, but I'm old enough that the supermarket I went to as a kid had these at all the checkout aisles and the cashiers would use them to send cheques/reciepts/ whatever.

It was awesome to see.

[–] ghashul@feddit.dk 23 points 1 month ago (1 children)

They still use them today in some supermarkets, now they use them to send packets of cigarettes through the store.

[–] Omega_Jimes@lemmy.ca 8 points 1 month ago (1 children)

That's actually a pretty good use. In my local market they send the person to a separate counter.

[–] 5wim@slrpnk.net 17 points 1 month ago (1 children)

Very cool, I've never seen the ones that can send a person. Can they breathe in transit?

[–] Cenzorrll@lemmy.world 7 points 1 month ago* (last edited 1 month ago) (1 children)

It's pneumatic, not vacuum. Geez.

[–] 5wim@slrpnk.net 3 points 1 month ago

Making it dangerous to smoke while in transit. I see why the people ones didn't catch on in the 50s.

[–] dharmacurious@slrpnk.net 11 points 1 month ago (3 children)

Okay, maybe my town is just not up to date, but these are still in use at all the banks and pharmacies where I live. Are they phased elsewhere?

[–] Omega_Jimes@lemmy.ca 6 points 1 month ago

I haven't seen one in years, but the fact that they're all used is awesome.

[–] kilgore_trout@feddit.it 1 points 4 weeks ago (1 children)

They are used in some hospitals in central Europe

[–] Kryptonidas@lemmy.wtf 1 points 3 weeks ago

In the Netherlands I see them in nearly every big hospital. I think for sending blood samples to the lab quickly. (Possibly among other things)

[–] FlyingSquid@lemmy.world 1 points 4 weeks ago

The Kroger pharmacy here replaced their awesome pneumatic tube with a boring sliding drawer.

[–] SGforce@lemmy.ca 32 points 1 month ago (2 children)

Some downtown big cities had the buildings interconnected.

[–] thehatfox@lemmy.world 30 points 1 month ago (1 children)

Prague had a large pneumatic post system which operated for 100+ years.

Prague pneumatic post.

[–] magnetosphere@fedia.io 4 points 1 month ago

I had no idea there were systems that spanned entire cities! Thanks for the link!

[–] tnarg42@lemmy.world 22 points 1 month ago (3 children)

Big hospitals still have them to send medications and random lightweight stuff around the complex. My wife has worked in two large hospitals that had pretty extensive tube systems, used especially with pharmacy.

[–] JackFrostNCola@lemmy.world 5 points 4 weeks ago* (last edited 4 weeks ago) (1 children)

Tom Scott does a youtube video about one in Canada (IIRC) where they send radioactive medicine from the lab a down the road to a hospital due to the half life of the medication making traditional transport (ie vehicles) impractical.

Edit: bothered to look it up

[–] fermionsnotbosons@lemmy.ml 2 points 4 weeks ago

I know of a hospital where the local university sends tracers with F-18 for PET scans in much the same way. Half-life of 110 minutes.

[–] aimizo@lemmy.world 2 points 1 month ago

My Walmart has them for a pharmacy drive thru.

[–] Jiggle_Physics@lemmy.world 1 points 4 weeks ago

The two major hospitals, relatively near me, use a combination of tubes, and robots, to dispense medications. One is working on completely robotic food service, and has completely robotic floor cleaning/polishing. Both, also, have robots that do the basic landscaping maintenance, like mowing/edging. There is more, it is interesting to walk around and see all these infrastructure systems work. Feels, at least partially, like the promised future of sci-fi.

[–] CrayonRosary@lemmy.world 4 points 4 weeks ago (2 children)

Before ATMs, bank drive-throughs (the ones with multiple lanes for cars) had pneumatic tubes to send cash and checks to the bank teller, or receive cash.

Some probably still do. I feel like I used one within the past 10 years.

[–] MrShankles@lemmy.world 3 points 4 weeks ago

They're still in use at most banks where I live. Most hospitals use them too; way faster than dumbwaiters

[–] magnetosphere@fedia.io 2 points 4 weeks ago

I remember those! I wouldn’t be surprised if they’re still in use. I’ve never used the drive-through lane at my bank. I can deposit checks online by taking a picture of it (which still seems weird to me), and I use the ATM for everything else.

Hate someone in the office? Pour hot coffee into the container and send it to your victim.

[–] BearGun@ttrpg.network 3 points 4 weeks ago

The factory i work at occasionally still uses them for delivering tests to the lab, pretty cool to hear them swish around in the pipes.
