Fan ducts for airliners.

We've gotta reroute all these ducts.

And the hydrothermal vents were in an acidic environment.

They're exhaust vents of some type.

Disappeared into one of the cooling ducts.

I think I have no tear ducts.

We also found the deepest vents known yet 5,000 meters the hottest vents at 407 degrees Celsius vents in the South Pacific and also in the Arctic where none had been found before.

This is one of these hydrothermal vents.

It's how they find the hydrothermal vents.

Go in through the air conditioning vents.

The vents are emitting a black body radiation an IR signature and so they're able to find these vents at considerable distances.

He's in the vents! He got the diamond!

You see the sunbeams coming from the ventilation ducts and the train approaching.

No question. It's using the air ducts to move around.

We're all choking, and there's smoke pouring through the vents, under the doors.

And he can't understand how this barbarism can be tolerated, and he vents his frustrations.

We can't fix it out here anyway and we need to reroute a couple of ducts.

It wasn't my fault, really. Sebulba flashed me with his vents.

He inspected the air conditioning ducts last year, computer relays the preceding year.

So we repair the barricades at these two intersections, and weld plate steel over these ducts here, here and here.

Clean out the air ducts in your home, in your workplace, in your school.

Everything was painted typography over the whole damn thing, including the air conditioning ducts.

And we also found this spectacular yeti crab that lives near boiling hot hydrothermal vents at Easter Island.

This will allow heat and chemicals to escape through hydro thermal vents, providing more comfortable conditions for underwater life.

Knock it off. I catch you playing in the air ducts again, I'll tan your hides.

I need to see air ducts, electrical access tunnels, subbasements, every possible way into this complex.

So at those deep oceanic vents, fantastic chemistry began to happen, and atoms combined in all sorts of exotic combinations.

Since this space is a waiting room for outpatients, we usually keep a lid over the vents.

And before the discovery of these vents, all life on Earth, the key to life on Earth, was believed to be the sun and photosynthesis.

Cool air usually comes out of the ceiling through the air ducts, cooling the whole room at full blast.

Monsters, I'm so proud of you, I could cry, if I hadn't lost my tear ducts in the war.

They commissioned a group of their best scientists to investigate, and what they found was that all these tape drives were located near ventilation ducts.

What we found is that these rooms remained relatively stagnant until Saturday, when we opened the vents up again.

Lister, a loose animal aboard this ship could get anywhere. It could get into the air ducts, it could get into Holly.

In their way they saw many whales sporting in the ocean, and in wantonness fuzzing up the water through their pipes and vents, which nature has placed on their shoulders.

It fits exactly where we need to fit it, right in the center of the hubs of the ducts in the system very critical.

We find microbial life in every part of the planet in ice, in coal, in rocks, in volcanic vents it's an amazing thing.

So with Firefly, what we did is the problem is electronics get hot, and you have to put in vents or fans to keep them cool in most products.

And taking them down so that they had access astrobiologists, planetary scientists, people who were interested in these extreme environments taking them down to the vents, and letting them see, and take samples and test instruments, and so on.

The red dot is the laser light of the submarine Alvin to give us an idea about how far away we are from the vents.

So, having done these expeditions, and really beginning to appreciate what was down there, such as at the deep ocean vents where we had these amazing, amazing animals they're basically aliens right here on Earth.

I was seeing creatures at hydrothermal vents and sometimes things that I had never seen before, sometimes things that no one had seen before, that actually were not described by science at the time that we saw them and imaged them.

Now you've heard of hydrothermal vents, but the other discovery is that deep below the sea floor, there is vast reservoir of microbial activity, which we have only just discovered and we have almost no way to study.

So, we put the room service menus over the vents in the wall, we put blankets at the bottom of the door, we put the kids on the windowsill to try to get some air.
