Fossilised.

Coal is a fossil fuel.

It's a fossilized worm.

Fossil record study?

Intrinsically safe environments

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

Without it, we'd be in serious trouble.

and food into people.

And every single oil is different when it hits water.

Linear take, make, waste.

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

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

As the pressure grew, so did the heat, until a chemical reaction transformed the organics into hydrocarbon fossil fuels

And you could actually find full fossil evidence of these.

We now rely on distant countries for basic necessities.

What is today completely impossible get rid of our dependency on fossil energy.

Ralph Waldo Emerson described language as fossil poetry.

Suburbia, and many communities were designed on the assumption of plentiful oil and energy.

We've talked about the soil erosion.

Of those, only nuclear and hydro are green.

Electric cars run on electricity.

20,000 years ago in Germany, their skulls were identical to ours

Improvement of natural energy technology

So we went out and collected a whole bunch of stuff and we found a whole bunch of little ones.

And they changed the atmosphere.

He is a living fossil!

The continent is abundant in fossil fuels.

So the hypotenuse is now going to be five.

So one of my graduate students, John Scannella,

What is life after fossil fuels going to be like?

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.

And what's really important about dental calculus is that it fossilizes just like the rest of the skeleton, it's abundant in quantity before the present day and it's ubiquitous worldwide.

Coal is chemically allied to diamonds.

But before it was fossil poetry

But I also am in the fueling business.

They're everywhere, they're all over the place.

She took the bone, and she dumped it into acid.

You know, you're gazing upon your very distant ancestors.

We just dug up a new skeleton...

This is the Stone Age.
