The devices that computers use are what's called a transistor.

They landed near the Verteron Array.

It's no more than an anode and a cathode separated by an electrolyte, right?

That's a little better. Woman That side is better.

And his thoughts made him reach for Katie.

Volta's battery works at room temperature.

I'm picking up a power surge in the array.

Without the array to divert them toward the polar caps, the comets could hit anywhere, even the domed cities.

This is where the supply of current flows out from, you see?

Target the directional array on grid 459.

I've just taken over the Verteron Array on Mars.

I've just taken over the verteron array on Mars.

We can now reach those circuits.

Your electrodes came off last night.

This electrode here, called the gate, controls the flow of current from the source to the drain these two electrodes.

So this is what we did.

And this forces magnesium to de alloy and return to the upper electrode, restoring the initial constitution of the battery.

This is Frank Drake's electronics in 1960.

like the one that you can see here in the photo.

Our targeting array is still down.

The verteron array is on the other side of that rise.

Someone's tapping into the telemetric array.

This is work done with my colleague Helen Mayberg from Emory.

I've got a real estate problem.

They put electrodes or sensors on my head.

Miss baum's electrodes must have slipped off again.

One part of the virus grabs a carbon nanotube, the other part of the virus has a sequence that can grow an electrode material for a battery, and then it wires itself to the current collector.

So this looks something like this.

This is the place where the meditators you can see it's kind of inspiring.

I'll be back later to attach your electrodes.

Enterprise will destroy the array as ordered.

In the 1950s,

And that current, electrical current, is carried by electrons, just like in your house and so on.

This is the starting point for designing a battery two electrodes, in this case metals of different composition, and an electrolyte, in this case salt dissolved in water.

We stimulate one place, the other place. We can stimulate lots of places.

Here's one that's in prototyping by Medtronic that's smaller than a penny.

The lights are out in these areas of the brain.

And here we can see him getting the therapy.

Now they know what part of the brain they can remove in order to cure the patient.

And what you have here is, when you actually turn on the gate, you get an increase in the amount of current, and you get a steady flow of current.

The 21st century now allows us to build bigger glasses much bigger glasses.

All this paraphernalia. He might panic.

And the astronauts went up and experienced the pinnacle of separation.

This is the Allen Telescope Array, about 350 miles from whatever seat you're in right now.

I won't destroy the array unless we have no other choice.
