The GlowintheDark Flashlight!

I've got data to back up all these assertions, by the way.

This makes a Hydrogen economy unlikely.

We can do the same for geothermal energy and solar power.

As of 2007, there are only about 4 square miles.

I love renewables. But I'm also pro arithmetic. (Laughter)

light bulbs, light.

Now we weren't actually going to put Archimedes in that beam.

I ran like lightning.

I ran as fast as lightning.

But the pay off is really enormous.

China leads their explosive growth and their plummeting cost.

I have a stake in these, so I'll have a disclaimer there.

In fact, if you flash them with a camera they catch on fire.

(Laughter)

And guess what?

And in six months they can become solar engineers.

(Laughter)

Went straight to the president.

Well, the GlowintheDark Flashlight, that was mine.

Mr. Wangdu, I can't believe it's you

For the first time, this year the cost of solar generated electricity is 50 percent that of diesel generated electricity in India 8.8 rupees versus 17 rupees.

Now that we have concentrated sunlight, what are we going to put at the center to convert sunlight to electricity?

He finished it as quick as lightning.

(Laughter) (Applause)

They're speaking to each other and actually becoming solar engineers.

She turned off the lights so she could enjoy the moonlight.

Now how are we going to do that?

This is Chuck Fleming in Times Square.

You probably think the electrons in an electric wire move instantaneously down a wire, don't you, at the speed of light when you turn the light on.

Now, think about where the world would be today if we had the light bulb, but you couldn't focus light if when you turned one on it just went wherever it wanted to.

That's a third of the U.S. population.

So, about two and a half hours of the day we could collect with a stationary component.

This has to be a bridge to the point where you can get to wind, to the point where you can get to solar, to the point where you can get to nuclear and hopefully you won't build the next nuclear plant on a beautiful seashore next to an earthquake fault.

Artificial light is produced by means of electricity.

Artificial light is produced by electricity.

Yeah. I believe we don't really appreciate what we have, and I only speak for myself.

Two terawatt hours, it's roughly half what the U.S. solar industry produced last year.

CA All right. So this is only one string to your energy bow.

But on the other hand, we have 14 billion of these

pennsylvania's exercising leadership on solar power and wind power.

We're often told though that only coal and nuclear plants can keep the lights on, because they're 24 7, whereas wind and solar power are variable, and hence supposedly unreliable.
