So I said, well, I know how to fix this.

All you need to do is make an artificial star wherever you like, because there's a layer of sodium at 100 kilometers.

And we now have lasers that will excite that.

And so you can make a yellow star that's plenty bright enough.

to use that light to adjust the mirror wherever you like.

And nobody had ever heard of the sodium layer during that.

This was top secret meeting.

A bright source of light shining down through the atmosphere.

Most of the problem is fairly close to the ground, the first kilometer or two up.

And what would this be made out of?

So if you go to 100 kilometers, the earth is plowing through the dust of the solar system.

And so we're constantly burning up little micro meteorites.

And they're all loaded with sodium atoms.

And so they get released into the upper atmosphere and they stay there and make a layer that's about 10 kilometers thick.

And not many people know about that.

I happen to know about it.

And I knew you could use it, you know, for this method.

That's why I got called to Washington.

It was a highly secret invention for 10 years.

Wow.
