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?

It appeared dead.

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

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

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.

The result is planes are 300 times

So the conclusion is planes and cars are roughly equally fuel efficient.

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?

Only if you control and regulate it, you will get that aerodynamic efficiency.

Normally, efficiency is crucial because the fuel cost of your engine over its life dwarfs the cost of the engine.

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.

General Electric natural gas turbine, you'll get about 60 percent efficiency.

The source of fuel crude oil.

Jet fuel.

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

We also discovered that efficiency doesn't matter so much if your energy source is free.

Rp7 rocket fuel burns at 5.000 degrees.

like water, forests, soils and fish faster than they can be replenished.

Fuel, Skripach, fuel...

It's chemically fueled.

Fuelinjected.

But if people start having expectations that wages will go down, that prices will go down then, they all go into panic mode and they stop spending.

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

But I'm not really concerned about the fuel.
