OK, this is Mount Everest.

(Laughter) And so we've been working on a chassis of the wall itself.

I keep repeating the words to my self But I can't give voice to them

Well, a man can dream.

And that's Mount Olympus on Mars, which is a kind of huge volcanic shield on that planet.

A little village from the area here.

They fixed the sign to the wall.

It was a very productive silver mine.

High walls. lots of cameras. guys with guns.

So, I would sleep in a hypoxic tent every night.

This is a view of base camp.

But his biggest shot yet to come

I'll take you to the top of the Himalayas.

OK, this is the route up Everest.

Let's do b right there. b is at the coordinate let's see, its x coordinate, and just drop down there, is 7.

There are high walls about the town.

Antarctica.

It's altitude is even higher than Mt Fuji About 3800 meter

And they live up on the Chang Tang, the Tibetan Plateau, way in the western part of the country.

High performing systems are very clear what good performance is.

We know where they are, and we're going to go and get them next year.

And this match, again, is called product market fit.

So negative 6, that's right there.

What is the altitude of the plateau?

They're pulling off the highway.

In high altitudes, people find it hard to breathe.

And they threw up walls political walls, trade walls, transportation walls, communication walls, iron curtains which divided peoples and nations.

You can barely stand outside the tent.

Elevation 2590 meters speed decreases with time of flight

And at this altitude, I can run flat out for a halfmile before my hands start shaking.

Below the threshold we perceive things as they are.

And a group at Itch, which is now part of IDEO, designed this interactive wall that's about four stories tall.

Every thousand feet above, is a whole new set of equations

So these are the results.

We can stop at nine billion if we do the right things.

The stars themselves

It was the sweetest, most mysterious looking place any one could imagine.

I want you to estimate the height of the building.

Here is another example of a part that we want to ID grip

I exercise. (Laughter)

The thing blocking my path was a stone wall of less than 1 meter's height.

They had to climb a wall six feet high.

The Berlin Wall?

But the laws are kind of like sushi in a way there are all kinds.

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