There’s so many levels to this. Like a hotel.

I can't find the revolving door! What level is it on again? What side of the building? Damnit, I feel so inadequate.

Just remember to push the little button on the side of the door first

Fellas, there's no point arguing with the flight attendants about wireless signal safety. Just smile and lie that you've switched it to airplane mode.

[–] LwL 25 points 2 weeks ago (1 children)

Yea, they just have to enforce it, not make sensible rules. Just let them do their jobs in peace and go petition the relevant aviation authorities if it bothers you that much.

[–] [email protected] 9 points 2 weeks ago (1 children)

Nah, fuck that. Anarchy forever. People should break pointless rules. But they should also lie about it when it's a hill this pointless to die on.

[–] LwL 23 points 2 weeks ago (1 children)

Oh no I agree, feel free to break that rule, just don't make it the flight staff's problem.

Oh, sorry for misunderstanding

What a pleasant exchange.

Just one question, can dragons give consent?

[–] [email protected] 2 points 2 weeks ago

Some can. There's lots of different kinds of dragons across the multiverse. Drag's engaged to marry a dragon who is entirely capable of speech, reasoning, and consent.

it's not for safety anyway, it's to prevent the cell towers on the ground overloading when 200 phones connect and then disconnect in a second.

Until all the lights flicker in the lobby

OK but is this actually a thing that happens? Can the door motor feed back into the grid, or are there safeguards against that?

[–] [email protected] 21 points 2 weeks ago (1 children)

As a prospective electrical engineer, i sure hope there's a safeguard against that, since i believe it would be quite simple and cheap to include. If you spin it fast enough you might overload and fry it though, even if it is there.

[–] Buddahriffic 3 points 2 weeks ago (1 children)

Would it be possible to put the energy generated back into the motor to make it easier to spin it faster? Maybe use some capacitors to have it switch between generator and motor mode on a repeating cycle?

[–] [email protected] 4 points 2 weeks ago (1 children)

It's definitely possible, but I'm having a hard time trying to justify it. The amount of power a motor like this would draw i very low, so a few percentage points here or there doesn't matter. The complexity of the circuit can quickly become fairly complex with something like this and i doubt the extra manufacturing costs would be worth it. Especially not for the seller, since they could easily (and probably do) just write in the warranty or whatever to not spin it excessively.

[–] Buddahriffic 1 points 2 weeks ago (1 children)

Yeah I was just curious because it's a difficult thing to wrap my mind around on the physics side of things. Like it is capable of generating energy and that energy could be used to spin the motor, but the two parts are opposites. It's like using the energy from a flywheel to spin that same flywheel.

[–] cam_i_am 2 points 2 weeks ago

In general it is often true that a motor and a generator are two sides of the same coin.

If you put a current through a wire you can make a magnet move which can be used to spin a motor. And symmetrically, if you spin a wire and make its magnet move near a wire you can induce a current in the wire.

Depends on the exact wiring and stuff but yeah sometimes you can damage a motorised device by manually spinning the thing without turning it on.

Can someone explain this to me ? Imagine I'm neither a native english speaker nor a revolving door engineer

[–] EmpathicVagrant 11 points 2 weeks ago (2 children)

Someone latched onto the phrase ‘hotel-masturbating’ and things turned into ‘how to bring a hotel (building) to climax.

[–] [email protected] 7 points 2 weeks ago (1 children)
[–] [email protected] 1 points 2 weeks ago

yeah, just like that

[–] [email protected] 3 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

but what was it supposed to mean initially ? people who masturbate in hotels ?

I'm getting Hotel Royale flashbacks.
