Palm tree plantation in Borneo.

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.

The conclusion drag is proportional to area.

Being generous to concentrating solar power,

Let me scroll over.

Remember those increased summer time daylight hours?

I was the only human being in an area one and a half times the size of America, five and a half thousand square miles.

Now, if that happens, insects will attack from every point.

Good thing they had that number there so I could try it out.

A cube 20 miles on each side.

We learned in the imaginary numbers video, that hopefully you've watched, that every now and then in certain equations you end up with a square root of a negative number.

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.

You can always every perfect square has a positive or a negative root.

And so you see that this is roughly a little over 23 about 23 and 1 2 miles per hour.

On an average how many miles do you walk a day?

And so the first house has size two hundred four square feet, has three bedrooms second house has sixteen hundred square feet, has three bedrooms and so on.

When we're taking the square root, it's not just the positive square root.

Now I would argue, actually, if you look at the fact that on the highways today, you're only averaging about 30 miles per hour on average, according to the DOT the Skycar travels at over 300 miles an hour, up to 25,000 feet.

Where are you?

We can get another square furgle on there and we can get a third square furgle on there!

And yes, it's US 30 per square foot.

And then you get y is equal to and I'm doing this on purpose the plus or minus square root, because it can be the plus or minus square root.

Let me ask you the same question.

If some of you play chess, you'll know that 64 is a square number, and that's why chessboards, eight by eight, have 64 squares.

And two, there are better ways to do this.

I just the square root of it, and we have to get the square root of the denominator too.

Sum of all data items squared

The area is equal to (let me write this down)... We have (let me write it down)... We have

The suspension bridge is miles above.
