How Ancient Roman Automatic Doors Worked 🤔

Interesting, but never built. The mechanism shown is from a conceptual drawing by the Greek engineer Heron, working in Egypt under Roman rule. Archaeological evidence shows no traces of this complex pneumatic system ever being built. The concept, however, was ahead of its time.

average citizen must have though of it as magic

Ancient engineers > half the startups today 💀

me when i start a fire and wait an hour for the heat to boil water and fill a bucket instead of simply using my hands to open a door

Did this actually exist or is it just someone's fantasy? Where's a real example of it?

Bro they had better tech than my society’s building 😭🚪

Ancient Rome was basically running on pure genius energy 🧠⚙️

Reminds me of this 😤😤😤

How A Glass Drop Shatters Bullets 🤔

I hope no one is stupid enough to think any civilization is going to build this complicated bullshit just to wait for a log burning over 30 minutes to open a door. A door that opens against the weight of small bucket of water.

Interesting but incomplete at best - what closes the doors? Less weight in the bucket won't do it alone, must have another counter wt or something

They really said automation 2,000 years ago 😭⚙️🧠

Heat travels up... not through a pole underground to heat ware in a ball.

That's pretty genius. Considering we still utilize hydropneumatic doors, this has to be along the world's oldest technologies.

Imagine walking into a temple and it auto-opens… peak vibe 😭🔥

I have news for you, that is an Ancient Greek invention that was used by Romans. Romans mostly apprehended Ancient Greek inventions.

Romans basically invented ‘smart doors’ without electricity 😮‍💨

Oh that’s how that works, and here I thought this was so fake in god of war

Bro Romans were doing IoT before it was cool 😭⚙️

The physics seem dubious. Even if the heat from the fire travelled all the way into the tank, which already seems iffy, why doesn't the expanding air simply escape towards the path of least resistance, i.e. towards the fire, rather than starting to push the water out of the tank?

Automatic doors without sensors… Romans were different fr 😮‍💨

I never knew the fire heat can travel downward 🤔

It must have been such a pain in the ass to wake up in the middle of the night in Ancient Rome and go through all this just to open your bathroom door.

so you had to light a fire and wait around for 15 minutes lmao

Rome Goldberg machine

Some people will think it was done by Aliens

ancient tech was lowkey insane for its time

And it took only 12 minutes for door to start moving.

How Khazad-dûm doors worked

Shit that never happened /10

So this would be chemical energy -> kinetic transfer? Cause the burning fuel is actually doing the work

🤔So that's how they functioned🤔

Public school has failed every single one of you. Assuming this all works and would open the door, the water is now in the bucket. There is no emptying of the bucket or refilling of the initial container built in to this.
