Due to the shortages of such basic commodities as fuel, food and drinking water.

Oh, well, actually they theoretically can separate the hydrogen from the oxygen and process that into providing fuel for manned space flights.

I was, you can see there, pulling two sledges.

Now, I'm not trying to pick on pancake mix.

I really only see five that can achieve the big numbers.

I need fuel.

Primary fuel?

Fuel supply?

Our fuel.

Pasta is high in carbohydrates.

Let's say we converted all the vehicles in the United States to battery electric vehicles, hydrogen fuel cell vehicles or flex fuel vehicles run on E85.

The result is planes are 300 times

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

Mine fuel

Primary fuel 2893 KRG.

What is he saying about the fuel?

Fuel cells.

In a nuclear power plant, you have a big pot of water that's under high pressure, and you have some fuel rods, and these fuel rods are encased in zirconium, and they're little pellets of uranium dioxide fuel, and a fission reaction is controlled and maintained at a proper level, and that reaction heats up water, the water turns to steam, steam turns the turbine, and you produce electricity from it.

My only instruments are an altimeter and time.

It's only halffull but it's functional.

And this is pure drinking water.

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

And lithium is in sea water. That's the yellow line.

The fuel cell looked great one tenth as many moving parts and a fuel cell propulsion system as an internal combustion engine and it emits just water.

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

The source of fuel crude oil.

Jet fuel.

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

Strong smell of gasoline.

Don't let me skip over that. Better biofuels are a really big deal.

Rp7 rocket fuel burns at 5.000 degrees.

Fuel, Skripach, fuel...

It's chemically fueled.

Fuelinjected.

But I'm not really concerned about the fuel.

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

All right, you got enough juice in those jetpacks to get up there, but not enough to make it home.

We've talked about the soil erosion.

The EROEI for oil today is as low as 10.

As the water temperature increases, the wind velocity increases and the moisture content increases.

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.
