40 Watt incandescent lamp

100 Watt incandescent lamp

200 Watt incandescent lamp

That's 200 watt hours.

This is Stephen Watt.

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

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

A back of the envelope computation for a 40 watt bulb, shows that it emits about 10 to the 19th photons per second.

We start here with our workhorse one watt hour cell.

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.

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.

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.

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

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

You would need about 40 times as much to run a bright, 100 Watt light bulb.

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