Odd Lots
How the Invention of Rope Gave Us Modern Civilization

Hmm.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And the reason why it can do this is that there's this material called graphene.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

It's a very strange material.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And the way it's made is very strange.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

But it's basically carbon that uses gaseous depositation onto a copper substrate.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And when the conditions are right, it actually forms these hexagonal rings.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

They're all interconnected.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And those interconnected hexagonal rings use the strongest bond known in nature.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

Wow.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

But that's only one atom layer thick.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

Then you deposit it again and another layer forms and then another and another.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And you can go to 26,000 layers, as Adrian Nixon told me about.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And this tether is incredibly strong.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

I mean, it's unbelievably strong.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

You need something that's capable of 90 gigapascals of tensile strength to do this.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

And this graphene has been tested up to 120 gigapascals of strength.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

So it's very much capable of doing the job.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

The biggest drawback is that you have to have, it's a manufacturing drawback.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

You have to be able to make a tether 100,000 miles long with no brakes.

Odd Lots
How the Invention of Rope Gave Us Modern Civilization

So that's a little bit of a challenge.
