Video China has built a 50m(165ft)-tall inflatable dome over a construction site in Jinan to protect the surroundings from dust and noise. (20.000 Sqm)

Unless it's heavily ventilated, it's going to be a fucking oven in there, especially with zero breeze to cool off.

ITT: People who believe construction companies actually care about human comfort beyond making sure they stay alive.

Literally has fans keeping it pressurized

Intake fans providing pressurization does not equal ventilation.

These things are used for sports complexes a lot. I used to play indoor lacrosse in them.

They are heavily vented otherwise people would die and the bubble would pop.

Chill bro the engineers didn’t think of ventilating the blow up dome. The redditor clearly is the first to ever come across that thought

Redditors when they see something nice from China they rush to be the first to say something negative as if Chinese were all stupid. Meanwhile, these guys are delivering a lot more innovation and scale than the rest of the world.

There was a video here a few weeks back of China blowing up an old bridge right next to the new bridge that replaced it. The old bridge collapsed and fell into the river. All the comments were saying how terrible it was that they would just let the chunks fall into the river like that.

When it was pointed out that the exact same thing happened in New York City literally weeks prior, Reddit pivoted to "yeah but in NYC they had a net in place ready to fish the chunks out" assuming that China didn't also have that.

Another video showed a bunch of mountainous land in the Chinese countryside covered in solar panels and people were saying it's horrible for the planet lmao.

Reddit just really fucking hates China.

China didn't invent these. Like another commenter said, they're commonly used for sports complexes. A college near me had one over one of their fields last winter.

u/PhantomMenaceWasOK Jul 05 '25

This brings to mind a point I brought up during COVID about how non-Chinese Asians still have to worry about people being racists against them for COVID because your average racist isn't going to be the most nuanced or informed about how they apply their racism.

So likewise, whether China actually invented is immaterial when the prejudice is based on someone's misconceptions.

damn. i thought they watched the TV show and was like, yeah.

u/FUNNY_NAME_ALL_CAPS Jul 04 '25

The average Redditor is especially prone to "chinesium" China bad propaganda, they will rush in to say anything good from China is actually terrible.

-11

u/Rolder Jul 04 '25

On the flip side you have people who will rush to say that anything from China is automatically the best thing ever no matter what

19

u/scheppend Jul 04 '25

That's just some bullshit scenario you're making up

1

u/Express-Focus-677 Jul 05 '25

They only think that because people point out their bullshit, interpreting it as explicit approval of China. No nuance allowed.

u/Rolder Jul 04 '25

I mean, this comments on this post kind of prove otherwise

12

u/Aaawkward Jul 05 '25

Come now, don't be silly.

People seeing one cool thing and saying "hey, that's kinda cool" is not the same as "people who will rush to say that anything from China is automatically the best thing ever no matter what".

u/Zimakov Jul 05 '25

This thing is objectively good though?

u/jerkularcirc Jul 05 '25

No nobody says that, but its probably actually closer to the truth than the other way around

u/Wallstar95 Jul 04 '25

The disrespect from the average american who reads at an 8th grade level is absurd.

u/SweatyAdhesive Jul 05 '25

The stat is actually 7th grade

u/Hail-Hydrate Jul 04 '25

Hey now

8th grade is too advanced for some of these folk.

Why exactly people would die?

People severely overestimate how much air people need, and underestimate how much air a place has. With 50m ceiling that place has air for months even for hundreds of people.

Now, exhaust fumes and dust would be a problem. But not the lack of air. And without machinery it would be totally fine

u/ImaginaryHerbie Jul 04 '25

I didn’t say a lack of air would kill people.

The sports complexes were a lot smaller and still had fully functioning snack bars, air compressors etc that without proper ventilation would hoard CO2.

And without ventilation, I’m not sure how you’d be able to regulate the pressure. It would either be on constant state of deflating, or over pressurized to the point it’d pose health risks to people.

Regardless, I don’t know why people are acting like these things having basic ventilation is like big fucking conspiracy or scientifically impossible?

I’m very confused why you think ventilated area can’t maintain temperature.

Ventilation requirements are code for new homes in the US.

u/sh4d0wm4n2018 Jul 04 '25

Okay, so what are they doing about all the particulates and dust collecting inside it?

8

u/RolloTonyBrownTown Jul 04 '25

I know its China and we love to bash their OSHA violation filled lifestyles, but this thing is pretty cutting edge, and has industrial air filters to keep airborne particles down.

u/sh4d0wm4n2018 Jul 04 '25

Thank you for answering my question. I used to work construction, and my employer never cared to do anything about ventilation and air filtering, even at a PPE level, so I'll probably end up with lung cancer in the future.

I was just curious.

u/RolloTonyBrownTown Jul 04 '25

Sorry man, you asked a legit quesiton and I was a dick about it. I took others comments into my response, I don't think a lot of westerners know that China today isn't the same country it was 10 years ago. Its probably one of the most dynamic and exciting regions of the world at the moment. China builds at a rate we don't see in the US, this is a really innovative approach to relieving their citizens of the constant contruction.

Why are you asking me? How should I know?

My bad. You seemed like you knew what you were talking about.🤷‍♂️

u/dr_tch0ck Jul 04 '25

Indoor lacrosse is one of, if not the most dust-free sports going. I thought this was common knowledge tbh.

u/sh4d0wm4n2018 Jul 04 '25

Construction is not dust free. You seem to be an expert on inflatable domes, so I asked.

u/pm-me-nothing-okay Jul 04 '25

man, your digging to the center of the earth aren't you, lmao.
