Well, the fuel consumption is proportional to the drag force.

They could slow down by about 50 percent.

The car consumes a lot of fuel.

How can we use this?

gas money.

They're relieving congestion, and they're frankly starting to save some fuel.

Blame high fuel costs, blame insurance premiums, blame technology.

Improvement of natural energy technology

A lot of environmentalists who are always trying to drive us towards using less energy, because all that energy's coming from the consumption of fossil fuel.

(Applause) So let's say the plane is 30 miles per gallon.

The global economy grows exponentially, at about 3 a year, consuming increasing amounts of non renewable fuels, minerals and metals, as well as renewable resources

I need fuel.

Primary fuel?

Fuel supply?

Our fuel.

So despite all sorts of experts like me flying around the planet and burning jet fuel, and politicians signing treaties in fact, you could argue the net effect of all this has been negative, because it's just consumed a lot of jet fuel.

So, traffic keeps flowing, so that means less braking, which means less accelerating, less gas and less pollution,

So I took the food supply of every single country and I compared it to what was actually likely to be being consumed in each country.

Mine fuel

Primary fuel 2893 KRG.

What is he saying about the fuel?

Fuel cells.

Col. Tigh, how much aviation fuel has been expended in this operation?

Taxes?

Partly through this debt system, the effects of economic growth have been spectacular in GDP, damming of rivers, water use, fertiliser consumption, urban population, paper consumption, motor vehicles, communications and tourism.

NASA described conditions that year as the worst since records began.

Let's see how far we can go by bending rules as we estimate the fuel efficiency, the miles per gallon of a 747.

The source of fuel crude oil.

Jet fuel.

What are the cost and expenses to operate the business model?

Rp7 rocket fuel burns at 5.000 degrees.

Fuel, Skripach, fuel...

It's chemically fueled.

Fuelinjected.

You can make ammonia out of hydrogen, which could be a fuel.

But I'm not really concerned about the fuel.

In this kind of reactor, you can't do that.

We've talked about the soil erosion.

Four, modern medicine.

I made a promise that the next time I would fly around the world, it would be with no fuel, independent from fossil energies, in order to be safe, not to be threatened by the fuel gauge.

I can't give you a fuel injection.

Drop the fuel tanks and pull up!

Fill her up.

Like those cars that run on corn.

We're losing fuel.
