And that's 24 karat gold. And it's constructed. I built it.

Kevin, can you help? Let me see if I can help us find the circuit board.

These are diatoms, single celled phytoplankton with skeletons of silicon ... circuit boards of the future.

I got the boards already built. They go right into the CPU.

So they're really small, generally, they're square and flat and hard, and frankly, most of them just aren't very attractive, and so my team and I have been thinking of ways to really change and mix up the process and the outcome of designing electronics.

So, I started this company called Solar Devices.

I love the Fab Lab. her first night in the lab because she was going to make the sensor.

A protection system has been built into this circuit.

With this system a protection circuit has been built in.

This system has a built in protection circuit.

When he sees her in person, he says it's an impostor.

It achieves this by rotating LEDs about two axes.

The protection circuit is built into the system.

Move. No. Move.

So each chain, or each element, wants to turn right or left.

So it's a really slow process, it's really expensive, and the outcome of that process, namely electronic circuit boards, are limited in all sorts of kind of interesting ways.

I built an amplifier yesterday.

It works because it's non conductive.

In Google's case, the world isn't as simple as just red and green.

Design a printed circuit board.

John built a bookcase.

That's what we've been building for the last few hours.

And then I started rubbing, very very gently, till some of the edges were quite square.

Now, let's take a look at how we can do this systematically so we can actually build an algorithm that can find answers like this.

Put it together ourselves.

Can you make it work?

And honestly, where we've gone through over the last 11 years, through an attempt to find ways of turning circuits and cells and parts and pathways of the brain on and off, both to understand the science and also to confront some of the issues that face us all as humans.

The mechanic assembled the engine.

But the bones of this thing are threequarters inch of cobalt alloy hard plate.

Can you set up the bike?

I stood with my arms folded.

And it was the first thing I ever built.

If you think about this, this entire conversation we've had was how to get the basic data so you can put together a revenue model that's based on fact rather than fiction.

One of them little old fiberglass shithouses.

(Music) (Laughter) (Applause)

Don't ask me that.

He learned how to put a radio together.

Von Neumann, and a logician, and a mathematician from the army put this together.

Circuit

What will the world look like in a tenth of a second?

Assemble three cars in four weeks? Ha!

So the question is, how hard would it be to assemble this, right?

It's like the parts list of your body.

You have at least two customers segments and you have two value props and attending revenue streams.

Only pieces now waiting to make sense.
