Coal is a fossil fuel.

Limestone pie and hot melted silver.

Without it, we'd be in serious trouble.

and food into people.

But after some nagging, I got him to do that.

Now there's no question about it at all we will only solve the problem of replacing fossil fuels with technology.

Linear take, make, waste.

It looks beautiful.

The only reason modern agriculture can get away with killing the life in the soil is through another use of fossil fuel.

The first tunnels date back to 60 B.C.

We call these slabs of the solid rock layer 'plates'.

We're not killing the colony we're taking a small core sample out of the top.

When this happens, they're compressed under tons of pressure, and turned into carbon based fossil fuels

We now rely on distant countries for basic necessities.

That.

Wonderful specimens.

But also, if there is something that we cannot reach because it is too high on a cliff, we have a little laser system which will actually zap the rock, evaporate some of it, and actually analyze what's coming from that rock.

Maybe they could extract carbon dioxide.

Well, we have to take a little excursion, and we'll start in central Texas.

This is called energy density.

We're running out of fresh water.

The world runs on fossil fuel.

Fossil fuel prices shot through the roof.

This stove burns oil.

This stove uses kerosene.

We've talked about the soil erosion.

Before WW1, all agriculture was Organic.

Electric cars run on electricity.

Improvement of natural energy technology

Petroleum was replacing coal as fuel.

All of the assignments involve hands on activities, from creating an outfit for a rock person... gt gt Student

The other side of the island is rock bluffs all the way down to the edge of the water.

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.

The continent is abundant in fossil fuels.

What is life after fossil fuels going to be like?

Great. And the fibre samples?

This one was a freebie.

They shouldn't be there. And we called it Lost City.

So, the idea is that if we fly around the world in a solar powered airplane, using absolutely no fuel, nobody ever could say in the future that it's impossible to do it for cars, for heating systems, for computers, and so on and so on.

Petrol is no longer a cheap fuel.

But I also am in the fueling business.

There's rock, lava base.
