Basically, by controlling the genes, you can control multiple materials to improve your device performance.

And you can do it the same, over and over again.

So something I think is very fascinating is

This is an overview of the solar cell prototype.

(Music)

I hope for a solar battery car.

I want a car that runs on solar power.

Upper left is a film they did on toy trains.

And Helios now begins the process of turning her back to the sun, to maximize the power from her solar array.

(Laughter)

And we thought a solar powered plane wouldn't really make sense, but you could do it and it would get a lot of publicity for solar power and maybe help that field.

And it needed to get much lower to be cost effective.

This is a new kind of solar cell that's based on how a leaf works.

Well there are many molecules that exist in nature, which are able to convert light into electricity.

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

We believe we're getting very close to something practical and affordable.

Since I installed solar panels on my house, my energy bill has been cut in half.

But that sure started me thinking about various things, and immediately, we began making a solar powered plane because we felt solar power was going to be so important for the country and the world, we didn't want the small funding in the government to be decreased, which is what the government was trying to do with it.

When all of these tariffs are reduced, the things that we're supposed to encourage, and jump start an industry, the industry collapses.

On an average adjusted day, a solar cell because the sun's moving across the sky, the solar cell is going down with a sine wave function of performance at the off axis angles.

You see, the battery is the key enabling device here.

Imagine making all of our hard materials that way.

And with 200 square meters of solar power on our plane, we can produce the same energy than 200 little lightbulbs.

And I brought one of those as well, that you can play around with outside afterward.

(Laughter)

So these molecules are called channelrhodopsins.

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.

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

All of our equipment, including film equipment, was charged by the sun.

It's been 25 years since I was doing this,

I'm, first of all, renewable energy's biggest fan.

There's a theory that if you can find a way to combine these elements into the design of a solar cell, you can harness 100 of the sun's energy.

China leads their explosive growth and their plummeting cost.

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

The special, light emitting objects,

This force could provide its own energy and water and not really have to be resupplied for say a month at a time.

What if we could harness them and convince them to not be an antibody that does something like HlV?

Also, what is he doing? Row, rowed.

Sun

The sun

The sun.

When blue light hits it, it opens up a little hole and allows charged particles to enter the eye spot, and that allows this eye spot to have an electrical signal just like a solar cell charging up a battery.

It's the only college which is fully solar electrified.
