Here's a piece of limestone.

Those white cliffs are a dense Cambrian limestone.

And it's just limestone, nothing really special about it.

Would it give this block of limestone new properties?

The core comes up as these cylindrical tubes of limestone.

And it's different than this limestone, you can see that.

And that's not snow that's what the white limestone looks like.

Now a block of limestone, in itself, isn't particularly that interesting.

We don't just want limestone dumped everywhere in all the pretty canals.

So it would all be built in stone, in French limestone, except for this metal piece.

And Lost City was characterized by these incredible limestone formations and upside down pools. Look at that.

And so here the protocells are depositing their limestone very specifically, around the foundations of Venice, effectively petrifying it.

But gradually, as the buildings are repaired, we will see the accretion of a limestone reef beneath the city.

But imagine what the properties of this limestone block might be if the surfaces were actually in conversation with the atmosphere.

Ray It was Crease Limestone, and that was produced by sea creatures 350 million years ago in a nice, warm, sunny atmosphere.

The mountains of Bashan are majestic mountains. The mountains of Bashan are rugged.

And if you look even closer, you'll see, in that limestone, there are little shells and little skeletons that are piled upon each other.

This is our protocell technology, effectively making a shell, like its limestone forefathers, and depositing it in a very complex environment, against natural materials.

And when you see mountains, remember mountains can be moved.

And architect Christian Kerrigan has come up with a series of designs that show us how it may be possible to actually grow a limestone reef underneath the city.

Again I lifted up my eyes, and saw, and behold, four chariots came out from between two mountains and the mountains were mountains of brass.

I love how they were able to preserve most in everything that makes you feel close to nature butterflies, man made forests, limestone caves and hey, even a huge python.

Qasr Al Hayr East The Umayyad limestone castle of Qasr Al Hayr East is in an isolated location in the middle of the Syrian Badia, 100 kilometres northeast of Palmyra.

I climb mountains.

And I turned, and lifted up mine eyes, and looked, and, behold, there came four chariots out from between two mountains and the mountains were mountains of brass.

The mountains tent pins?

And stabilized the mountains

The mountains tent pins?

And stabilized the mountains

And solidified the mountains.

And solidified the mountains.

and the mountains crumbled

and the mountains crumbled

And the mountains pegs?

And the mountains pegs?

and the mountains stakes?

setting firm the mountains,

and the mountains stakes?

setting firm the mountains,

and the mountains fragmented

and the mountains scattered,

and the mountains fragmented
