CA How much electricity?

This is Alfred Gonzalez.

They are adding energy to the clock in the rate of 2.5 Watts.

Hold on there. Will you listen to me?

As you might guess doing so would take a huge amount computation for even the most modest scene.

It's interesting, say, to take a 25 megawatt, 25 million watts, and you compare it to the standard big iron of an ordinary Westinghouse or Ariva, which is 1.2, 1.6 billion watts.

You are sitting, you are relaxed, you're looking at me.

Wind power produces a bit more 2.5 watts per square meter.

Joules per second, or Watts.

40 Watt incandescent lamp

100 Watt incandescent lamp

200 Watt incandescent lamp

watts

And here's a solar park in Vermont, with real data, delivering 4.2 watts per square meter.

So this weighs a little more than a tenth of a pound.

This, this is a FreedomBox.

Army issue! Take Dr. Russell to the infirmary. Run a check on him.

It's a very, very expensive proposition to use battery backup for the grid. It has not ever been able to be accomplished on a grid level before because of how much it costs to store a watt hour in a battery.

This is time consuming tinkering but it can eventually produce a breakthrough

Recording, sir.

It was such a useful idea that the metric system unit for power, the Watt, is named after James Watt.

And it's very important to be low power, and I hope that's picked up more by the industry.

Being generous to concentrating solar power,

And one of the great ones of all time,

So, this facility delivers 14 watts per square meter this one 10 watts per square meter and this one in Spain, 5 watts per square meter.

CA How big?

let me go back and look at what's been happening with solar cells.

I was walking from the elevator over here, and even just looking at the stage right now so there's probably 20,500 watt lights right now.

This lasts six months with no power absolutely zero power, because it loses less than a half a watt.

Those were major breakthroughs.

Energy crops deliver half a watt per square meter in European climates.

James Watt's steam engine of 1788 was a major breakthrough.

Basically they were able to light a 60 watt light bulb at a distance of about two meters.

And it's actually as much as your laptop computer it's just 10 watts.

During the day, the Nutmeg collects energy from solar panels on the roof of the wheelhouse, and from a 450 watt turbine up the mast.

I'm probably producing 150 watts at the moment.

Half of the world's population lives in countries that are already above that line.

Solar panels, when you put them on a roof, deliver about 20 watts per square meter in England.

But more interestingly, the thermodynamics of this say, you're never going to get more than 20 percent efficiency.

Last month, MlT put out a study showing that by the end of this decade, in the sunny parts of the United States, solar electricity will be six cents a kilowatt hour compared to 15 cents as a national average.

Solar parks, because of the gaps between the panels, deliver less.

That's one gigawatt in a square kilometer, which works out to 1,000 watts per square meter.

Those are lines of equal power consumption per unit area, which I measure in watts per square meter.

It's currently 10 billion miles away from Earth, transmitting with that dish, with the power of 20 watts, and we're still in contact with it.

There's 10,000 watts of light pouring on the stage, one horsepower is 746 watts, at full power.
