Powered by fossil fuel derived energy.

Nano engineered fuel cells could provide the energy where it's needed.

So much more energy can be stored with fuel than with batteries.

Fuel, Skripach, fuel...

linear by cyclical fossil fuel energy by renewable energy, sunlight wasteful by waste free and abusive by benign and labor productivity by resource productivity.

Your car won't go forever unless the engine keeps burning fuel to drive and consuming energy

The fuel shortage awoke the country to the need for developing atomic energy.

less than one percent of the fuel energy ends up moving the driver.

How much energy did the neutron have that you smack the nuclear fuel with?

Thermodynamics typically gives us about 30 percent of the energy when we burn fuel.

If you use more energy to get the fuel than is contained in the fuel, it's not worth the effort to get it.

Fuel the Jet, Fuel the Jet.

After all, the energy content of antimatter is a billion times higher than conventional fuel.

One unit like this is an energy unit of fossil fuel oil, coal or gas.

About 7 calories of fossil fuel energy are used to produce 1 calorie of food.

Well, in the long term, it's absolutely certain that present methods can't because they're so entirely dependant on energy, on fossil fuel energy.

It's the same energy question that you're looking at today, but it's different sources of fuel.

Every time you do so, some of the energy contained in the original fuel is lost.

Mine fuel

Primary fuel?

Fuel report.

Fuel supply?

Jet fuel.

Our fuel.

Fuel cells.

Fuel... power...

They have used the fuel of their pain to begin to redirect that energy towards another mission and another trajectory.

Enthusiasm and energy

matter and energy.

And abracadabra, energy.

And they put fuel in here.

Fuel drive's spun up and ready.

And maybe its hidden agenda, an energy manifesto something that would be free, completely free of fuel as we know it.

So we embarked upon the reinvention around an electrochemical engine, the fuel cell, hydrogen as the energy carrier.

And all I could detect was this energy energy.

Because combining matter and antimatter would create so much energy, science fiction is full of ideas about harnessing the energy stored in antimatter, for example, to fuel spaceships like Star Trek.

I need fuel.

No fuel injection?

I require fuel.

We're losing fuel.

How much fuel?

Fuel the jet.

And his wife, the bearer of fuel,

Drop the fuel tanks and pull up!

And that's energy poverty.
