We're out of petrol.

You inject people with petrol.

Petrol is no longer a cheap fuel.

Tastes like petrol. That's what it is. Excellent.

Can you spare me a few liters of petrol?

Our car ran out of petrol after ten minutes.

They might have some spare petrol in that watchtower.

And left only 60 for petrol food and housing?

We didn't want to buy more petrol anyways. You animal!

Less petrol stations per capita the bigger you are not surprising.

I thought that it wrote Texaco! I wanted to stop for petrol!

Now, I didn't start this fire, but I did pour petrol on it.

We did see the petrol drum. That could've been in the water for months.

We truly, you know, have modest goals of replacing the whole petrol chemical industry (Laughter) (Applause)

And you have refining and delivery of that crude oil as what we call petrol or gasoline.

We put the big petrol barrel with a portrait of Mr. President on it, in the middle of the Main Street.

That is that the number of petrol stations in the city is now given to you when you tell me its size.

If you have a car that no one knows, and you know to borrow petrol with the help of hose, you quite some time to travel.

We recognize this is a finite resource, and it's simply crazy to do this, to put a liter and a half of petrol in the trash every time you get a package.

In a single cubic foot of this material about what would come around your computer or large television you have the same energy content of about a liter and a half of petrol.

In between, perhaps some more realistic options on the transport lever are electric vehicles, so electric bikes and electric cars in the middle, perhaps four times as energy efficient as the standard petrol powered tank.

This shows that in this very simple example, which happens to be a mundane example of number of petrol stations as a function of size plotted in the same way as the biology you see exactly the same kind of thing.
