This is a
solar
LED lightbulb that we sell for a retail price of about 10 dollars in rural Haiti.
And at night, I would go around sometimes and I would speak with the street vendors and see if they were interested in buying these
solar
LED lamps.
Rather, when smart autos exchange electricity and information through smart buildings with smart grids, they're adding to the grid valuable flexibility and storage that help the grid integrate varying
solar
and wind power.
In fact, these
solar
power module costs have just fallen off the bottom of the chart.
And Germany now has more
solar
workers than America has steel workers.
Already in about 20 states private installers will come put those cheap
solar
cells on your roof with no money down and beat your utility bill.
In 2010, renewables other than big hydro, particularly wind and
solar
cells, got 151 billion dollars of private investment, and they actually surpassed the total installed capacity of nuclear power in the world by adding 60 billion watts in that one year.
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.
And in exactly the same way, the grid can handle wind and
solar
power's forecastable variations.
So here's our little
solar
system, as we pull away from our melted planet here.
Next, let's look at
solar
power.
Solar
panels, when you put them on a roof, deliver about 20 watts per square meter in England.
If you really want to get a lot from
solar
panels, you need to adopt the traditional Bavarian farming method, where you leap off the roof, and coat the countryside with
solar
panels, too.
Solar
parks, because of the gaps between the panels, deliver less.
And here's a
solar
park in Vermont, with real data, delivering 4.2 watts per square meter.
Remember where we are, 1.25 watts per square meter, wind farms 2.5,
solar
parks about five.
Concentrating
solar
power in deserts delivers larger powers per unit area, because you don't have the problem of clouds.
Being generous to concentrating
solar
power, I think it's perfectly credible it could deliver 20 watts per square meter.
And a fourth supply-side option: concentrating
solar
power in other people's deserts.
And this is the most powerful light source in the
solar
system.
And then I also have to say, this is the first step in us moving to other
solar
systems and potentially other galaxies, and I think this is the only time I ever out-vision Elon, because I want to meet other people in other
solar
systems.
I want to find people, or whatever they call themselves, in another
solar
system.
Together with the architects of Albert Speer & Partner, our engineers from Transsolar have been supporting, have been developing open-air stadia based on 100 percent
solar
power, on 100 percent
solar
cooling.
Our idea for the bid was 100 percent
solar
cooling, based on the idea that we use the roof of the stadia, we cover the roofs of the stadia with PV systems.
And this energy now is harvested throughout the year, sent into the grid, is replacing fossils in the grid, and when I need it for the cooling, I take it back from the grid and I use the
solar
energy which I have brought to the grid back when I need it for the
solar
cooling.
It was an astronomy book, and I poured over that thing for hours on end, and it was a combination of all these things that inspired me to pursue space exploration as my own personal dream, and part of that dream was, I always wanted to just fly around the
solar
system and visit different planets and visit moons and spacecraft.
Well, a number of years later, I graduated from UCLA and I found myself at NASA, working for the jet propulsion laboratory, and there our team was challenged to create a 3D visualization of the
solar
system, and today I want to show you what we've done so far.
Well, I can click on this home button over here, and that will take us up to the inner
solar
system, and now we're looking at the rest of the
solar
system.
Now, what happens is, as it flies underneath Saturn, Saturn grabs it gravitationally and flings it up and out of the
solar
system, so if I just keep letting this go, you can see Voyager 1 fly up like that.
And, in fact, I'm going to go back to the
solar
system.
