I studied all the new things that had happened in solar cells, and was trying to look for ways we could innovate and make solar cells more inexpensively.

It's been 25 years since I was doing this, let me go back and look at what's been happening with solar cells.

Chip

Some people even say it takes more energy to make a solar cell than it will give out in its entire life.

They are powered by the sun. Solar panels power them.

And this image of the sun may suggest that the sun is something evil and aggressive, but we should not forget that all energy on this planet actually comes from the sun, and light is only a manifestation of that energy.

Sun energy

Yes, it will take a solar panel. Yes a solar panel will charge it.

So I thought of an idea what if we collect the sun with a large reflector like I had been thinking about way back when, when I was in high school but maybe with modern technology we could make a cheaper, large collector, concentrate it to a small converter, and then the conversion device wouldn't have to be as expensive, because it's much smaller, rather than solar cells, which have to be covering the entire surface area that you want to gather sun from.

They accumulate the solar energy.

Solar power system

Indeed, there is excellent potential for low cost solar power, zero emitting coal based technologies, and safe and reliable nuclear power. Solar radiation equals roughly 10,000 times our current energy use.

Solar radiation equals roughly 10,000 times our current energy use. We tap that solar power in many fundamental ways food production, wind power, hydroelectric power, solar heating, solar thermal electricity, solar panels but the possibilities for greatly increased use of inexpensive, widely available, and environmentally friendly solar power are huge.

Solar can do it, and we certainly have to develop solar.

Solar power panels

And just to kind of put us in perspective, this is a picture of Saturn taken with a spacecraft from behind Saturn, looking towards the Sun.

Optical debris can be detected by reflected sunlight when the debris object is sunlit while the ground below is dark.

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

It presents the solar panel to the sun, and at night it's a street lamp.

They're really nothing but a few pieces of carbon, crystallized under high pressure at great heat.

It is spin stabilized with a Sun pointing capability and deployable solar panels.

And now, this is a picture of atoms in the Sun's atmosphere absorbing light.

You understand a solar chimney.

(e) Solar array (SA).

And the technology that we settled on as an ideal partner for the Seawater Greenhouse is concentrated solar power, which uses solar tracking mirrors to focus the sun's heat to create electricity.

MIT just has a new radio chip that uses far less power than our chips.

This company manufactures computer chips.

You get barefoot solar engineers carrying solar panels into the remote mountains.

The satellite is a modular type with a flexible solar array paddle.

And the granola house has a special Sun Chip roof to collect water and recycle it.

The sun! It's given you sunstroke!

And there's much more solar than there is wind.

Solar Cookers International

The sun can be vertically overhead.

It will have a three axis stabilized bus with two panels of solar arrays and batteries.

This is a picture of Titan, backlit by the Sun, with the rings as a beautiful backdrop.

Despite the country s massive investment in solar and wind, it mostly sells solar panels to Western countries at subsidized prices. Wind makes up just 0.2 of China s energy, and solar accounts for 0.01 .

There's plenty of solar and wind.

Meanwhile, back at TED University, this wonderful woman is teaching you how to chop Sun Chips.

So and then when you compare the lifetime emissions of these various energy forms, nuclear is about even with solar and wind, and ahead of solar oh, I'm sorry with hydro and wind, and ahead of solar.

How does nature gather the sun's energy?

A tremendous amount of energy is coming at us from the sun.
