The first tunnels date back to 60 B.C.

Limestone pie and hot melted silver.

Energy Return on Energy Invested.

But after some nagging, I got him to do that.

It looks beautiful.

According to the Roman scholar Pliny the Elder, citizens of the Empire believed that limestone from a quarry near Troy would dissolve flesh.

We're not killing the colony we're taking a small core sample out of the top.

Well, we have to take a little excursion, and we'll start in central Texas.

So I looked up a plastic so I decided that I could mine some of this modern day rock.

Here's from Big Sur, like they're little jewels.

Hands weathered and worn and proud of it.

Maybe they could extract carbon dioxide.

They shouldn't be there. And we called it Lost City.

And as we sit, exchanging free ideas with each other, there are still people mining coal in order to power the servers, extracting the minerals to make all of those things.

Digging Hassle

Here's from Big unclear , like they're little jewels.

Gerty, what is the status on Harvester 3?

The dip slopes in the overlying limestone, the orientation of the flora, shallow waters...

But he got great terms on it.

It's about 400 million years old.

And then they are fossilized over millions of years.

Separation technologies are going to be extremely important.

Over on the eastern side it's gentle, as you can see.

This is how you farm oil.

But also, if there is something that we cannot reach because it is too high on a cliff, we have a little laser system which will actually zap the rock, evaporate some of it, and actually analyze what's coming from that rock.

You also have a buffer zone that's 17 square kilometers.

Tura Caves

The crate is at the bottom of Ryder's Quarry.

All harvesters running smoothly.

Harvesters are fine.

In my time, where I come from, this is a simple mining vessel.

Latin'calx 'for'lime'

The energy of the sun, trapped in rock, harvested by machine from the far side of the moon.

I know about the dig.

Near one of the stalled harvesters...

Because you've got to include the man who grew the coffee, which was brewed for the man who was on the oil rig, who was drilling for oil, which was going to be made into the plastic, etc.

What we are going to be doing with that Rover as it drives around, it's going to go and analyze the chemical composition of rocks.

I picked this up at MlT. It's a little younger.

We're in Pole Canyon, looking west up the western escarpment of Mount Washington, which is 11,600 feet on top.

You can see some of the major fossil sites that we've been working in the north.

Your diamond you've all heard, probably seen the movie Blood Diamond.

The dead have been covered with lime.

That's a person down there by the wheel.

In Alberta people work nonstop, 24 hours by seven to extract as much oil as they can.

I'm just passing the last of the harvesters. Looks like John.
