So, Dave what's his chariot.

We're going to it where the tar is sorted and graded for different uses depending on its quality.

What will this chart be used for.

This is basically campfire jar which is low quality because of the high levels of tar and soot still present in it.

So it'll likely be pulverized and put in the pit.

What's the pit?

Well, you're familiar with carbon sequestration, of course.

No he's not.

None of us know what that is.

Did I know what carbon sequestration is?

No you don't.

Okay, well, I know carbon or carbon is French for car.

Good.

Oh, boy.

So.

And, Dave, you could back me up on this.

No chance.

Carbon square Station, as the name implies, is when you're at sea on a quest for a good car.

Because when you make it to land, you're going to need to drive.

Wow, that is so preposterously wrong.

I, I don't even know how to think about what I just heard.

Well, you know what they say.

Tomato.

Potato.

No.

They don't.

So carbon sequestration is the process of sequestering or storing carbon in the ground, rather than having it be released into the atmosphere to contribute to climate change.

Wait, so just burying char is a form of carbon sequestration.

You got it.

What about all the smoke from the fire it takes to create the char, though?

Doesn't that contain a bunch of carbon that pollutes the atmosphere?

Yes.

Smoke is actually the result of incomplete combustion, so efficiency is key.

If you build an efficient enough fire to achieve complete combustion, you won't be creating any polluting smoke.

But why not simply bury everything in the ground before bothering with all this char business?

Therein lies the rub.

Okay, check this out.

If I were to take this stick and bury it in the ground, what would happen to it?

A mole would bump into it.

Okay.

So next time you have a thought, I want you to give it a full two minutes before you let it come out of your mouth.

All right.

Carpe diem, bro.

Yeah, I can tell you don't know what that means.

All right.

Any actually plausible guesses?

Wouldn't this stick decompose?

Yes.

And how long do you think that take?

I don't know.

Well, a stick like this might break down within a year or two.

A large tree, perhaps a hundred or even several hundred years.

But if I bury this piece of jar in the ground, it'll be there for the next 5 to 10,000 years.

Oh, no way.

Way.

So you see that biological carbon is sequestered in the ground exponentially longer when it's in the form of char.

Is it only wood that can be made into char?

No, no.

Since all life on this planet is carbon based, virtually any once living material can be returned to its carbon foundation, which we call char.

But you don't want the material itself to catch fire, right?

Correct.

Ideally, you would heat up the material to the point that it would catch fire without it actually igniting.

But that doesn't make any sense at all.

You can't get something hot enough to catch fire and prevent it from doing so.

You want to wager on that?
