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

The term Watt goes back to James Watt, who came up with the concept of horsepower to measure the amount of power produced by a typical work horse.

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

40 Watt incandescent lamp

100 Watt incandescent lamp

200 Watt incandescent lamp

That's 200 watt hours.

This is Stephen Watt.

Babylon routed every watt

let's compare the amount of power it takes to run this grandfather clock to the power we'd need to run a bright, 100 Watt light bulb.

The output power of a one square meter solar panel is about one watt, so it is difficult to use solar power on a large scale at present.

This clock uses so little power that you could run almost 300,000 clocks using the same power it takes to run one 100 Watt light bulb.

I am Tee Watt Kaa, leader of this colony. What do you...

And the price had gone down from 10 dollars a watt to about four or five dollars a watt, but it stabilized.

And this has a nameplate capacity of two megawatt hours two million watt hours.

We start here with our workhorse one watt hour cell.

But Tee Watt Kaa said he doesn't need our help.

That's the power of visual storytelling, that's the power of dance, that's the power of music the power of not knowing.

We've been working on this, actually, as an alternative energy source, starting way back with Johnson amp Johnson, to run an iBOT, because the best batteries you could get 10 watt hours per kilogram in lead, 20 watt hours per kilogram nickel cadmium, 40 watt hours per kilogram in nickel metal hydride, 60 watt hours per kilogram in lithium, 8,750 watt hours of energy in every kilogram of propane or gasoline which is why nobody drives electric cars.

The total energy imbalance now is about six tenths of a watt per square meter.

The power of the moon... the power of our future.

The power plant of tomorrow is no power plant.

Okay, the first power is the power of will.

Okay, the other power is the power of courage.

Along the way we scaled up to the 20 watt hour cell.

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

James Watt didn't actually invent the steam engine, he just refined it.

Against abuse of power.

Of having all power

The power of darkness.

Of that brain power.

It's in the developmental power of entrepreneurship, the ethical power of democracy.

I fear abuse of power, and the power to abuse.

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

The power of education, the power of education frightens them. They are afraid of women.

I am bereft of power.

That's a lot of power.

It's the power of focus.

I've got plenty of power.
