This is Alfred Gonzalez.

Hold on there. Will you listen to me?

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

CA How much electricity?

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.

40 Watt incandescent lamp

100 Watt incandescent lamp

200 Watt incandescent lamp

watts

Joules per second, or Watts.

This, this is a FreedomBox.

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

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

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

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

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.

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,

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

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

CA How big?

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

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.

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.

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.

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.

Let me introduce you to a typical nuclear reactor.

The median is 1.98.

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 if you don't have grid supplied electricity, then the question of payback is a different one entirely.

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.
