Coal dust.

Trees give off oxygen and absorb carbon dioxide.

What we wanted to do was we wanted to find a way to harness this waste resource and turn it into a fuel that would be something that people could easily cook with, something like charcoal.

The woodcutter fells a tree with an ax.

It's the Tin Woodsman.

You'll find families like this who go out into the forest to find a tree, cut it down and make charcoal out of it.

The vessel was loaded with coal, lumber, and so on.

And the briquettes crumbled a little bit and we lost energy as they fell apart as they were cooking.

Now one of the reasons why there are so few trees is this people need to cook, and they harvest wood and they make charcoal in order to do it.

And also biggest coal mine here.

But one of the things that we found was when we did side by side comparisons with wood charcoal, it didn't burn as long.

The damage was so severe because the primary energy fuel in Haiti is charcoal, which is made from trees, which is made from trees, and it's left the country almost completely deforested.

But they're not just buying the juice they're also buying the carbon in the trees to offset the shipment costs associated with carbon to get the product into Europe.

Here's a piece of coal.

Have you ever tried spreading the Good Word? You mean, down in the coal mines?

And some of you might say, wait, how is that even a molecule? And just as a review, the end point of every line represents a carbon. So that's a carbon, that's a carbon, that's a carbon, that's a carbon, that's a carbon, that's a carbon.

Now, what does this have to do with energy?

And I don't know why, but I remember the story.

He strung a rope between the two trees.

And it is a bit of a problem.

Hold fast to this tree.

This is a violent process.

So one, two, three, four, five, six.

This is the story of how Harriet came to pay attention.

That is one big damn tree.

Carbon dioxide, having never gone above 300 parts per million, here is where CO2 is now.

So the number of neutrons can change, but this is carbon 12 right over here.

But I brought along here a lump of coal right here, one lump of coal.

Set here the charcoal pencil size used to simulate the drawing.

So that's the carbon nucleus in the center and then you have the hydrogens, so that's our carbon right there.

Canaries used to be used as kind of biosensors in mines.

In woodworking, we classify wood as hardwood, softwood or exotic wood.

And one of the things that I think is also interesting, is I have a friend up at UC Berkeley who's been doing risk analysis.

lots of mushrooms begin to form.

And here's a different way of mining coal.

Let's see, in carbon.

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

We took shelter under a tree.

I chopped a tree down.

Bears can climb trees.

Kijimasan.

Now, given what we just reviewed, let's think about what's happening with carbon.
