I want you to have 3 cups, a plateful of sulfur rich vegetables every day.

That's why you're building these pyramids of sulfur blocks.

Rp7 rocket fuel burns at 5.000 degrees.

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

We've talked about the soil erosion.

Michael and I were standing way at the side of the kitchen.

One deluxe sulfur soak

If we started today, 10 years from now, at the end of this window of opportunity, those fuel efficient cars will reduce our fossil fuel needs by four percent.

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.

We have a fuel leak!

It's like Michigan... hardcore propellant.
