Rat tunnel

Can't understand, loud 🔊🔊🔊🔊🔊🔊🔊🔊

I like this ancient method of cooling your home also. You can add pools of water at the bottom to further cool

Persian architecture in central cities of Iran like “Yazd” and “Kerman” where the desert is known for having one of the highest land surface temperatures on Earth, reaching up to 70.7 °C

What causes the colder heavier air to rise into the warmer house? In my house cold air stays in basement.

science for the rich, that cannot be used in overpopulated metropolis.

Way outdated. Google it yourself as to why.

Only made it 30 seconds in. Why do KZfaqr's always add music that is annoying and waaaaaay too loud? Bummed because I am very interested in this topic!

I need an architectural engineer to communicate with me to work in this way

The music is just to annoying 😮SMH

Low density, high density. Gravity need not apply!

The bedroom can be place acc to the person acc to vastu Sw and s are best place to have bedroom

Great idea to play music at that volume . I will find a quieter video............

stop before you watch lower the volume as far as you can or turn on closed captioning so the music doesn't give you headache

Should have titled it "How to grow mold in a pipe".

Channel name checks out

Rain enter your house

Dust catcher

thanks but it can`t be connected too internet after the change

No temperature numbers. So this is useless

very informative and useful

big love for u❤

At time 2.15 you said : Sherp angle makes more smooth flow ! Are you sure ?

Any technical references please? Something that can be used for putting together a detailed design? thank you

The music is very distracting do not included in your next video please

In the 1930’s, a similar system was set up in a hospital in Alice Springs, Australia, by the man who invented the Flying Doctors. 2 story building , with a tall turret. All windows and doors closed, except for the turret ones. Air inlet 2m outside the wall, feeding into the underground “hallway”. The hung 3 large hessian pieces, at intervals top to bottom in the “hallway”. The nurses and maids kept the hessian soaked, and had trays under to catch the drips. Each of the numerous rooms had a register in the floor, and the diagonally opposite corner of the ceiling. The first evaporative water-cooled house in Australia. Central Aust is a desert...0% humidity, up to 45deg C in summer. LouiseAustralia 🦘

The best air tunnel is the one that is submerged in subterranean water and with a type of aluminum honeycomb to better cool the air.

Buried at reasonable depth....... Video is a waste of time.

Wrong. One good thing is the video is mercifully short

Nothing good about this video. Nothing.

If you need to run a fan… pretty sure it’s it passive 😂

Such a tube would quickly become a maintenance nightmare invaded by rodents and overgrown by black mold. My lungs say "thanks but no thanks '. Instead it's well worth the small electrical cost to circulate a heat exchange fluid between the ground and air coils. Really

This will increase the weight of roof

What about Radon?

They should use that method to cool attics in houses which are nothing more than an oven on your home.

How is the sun gonna heat water in winter.... the air is freezing cold..

Why the music?.

It's not a cooling but minimal accetable air 😂😂😂😂

Sir water suply from water tank right ? Please tell

Carefully No Radon Gas gets in.

Great idea

Would have been good to go to a home with this system and get a temperature reading both inside and outside. See real world numbers, not just an explanation.

Mold in tunnel?

Not a wise idea. Bad utilisation of roof. Good for vertical walls. Instead put a jute shade 8feet above with bamboo support. Permeable and allow flow of wind.In extreme summer wet the jute toward dusk and it will cool the air beneath. Utilise the roof for more productive idea.

Arabic ancient engineering

Please remove the music

So tell me about Radon Gas

Interesting

Disgusting accent

This is interesting and actually very effective
