- The substance of the tree is carbon,
where did that come from?
It comes from the air.
It's carbon dioxide.
Yeah, people look at trees
and they think it comes out of the ground.
The plants grow out of the ground.
But if you ask where the substance comes,
you find out, where does they come from?
Trees come out of the air?
They surely come out of the ground.
No, they come out of the air.
No, they come out of the air.
The carbon dioxide in the air
goes into the tree and it changes it.
Kicking out the oxygen.
And then pushing the
oxygen away from the carbon
and leaving the carbon
substance with water.
Water comes out of the ground.
Only it came out of the air, didn't it?
Came down from the sky.
So most of it, almost all of it the tree
is out of the ground.
I'm sorry, it's out of the air.
Now, of course I told you
the oxygen and carbon
stick together very tight.
How is it the tree's so smart,
manages to take the carbon dioxide,
which is the carbon oxygen nicely combined
and undo that for some reason.
Ah, life.
Life has some mysterious quirks.
No, the sun is shining.
And it's the sunlight
that comes down and locks
this oxygen away from the carbon.
So it takes sunlight to
get the plant to work.
And so the sun, all the time,
is doing the work of separating the oxygen
away from the carbon,
the oxygen is some kind
of terrible byproduct,
which it spits back into the air
and leaving the carbon and water and stuff
to make the substance of the tree.
And then when we take the
substance in the tree,
and stick it in the fire place
It is the only oxygen made by these trees.
And all the carbon would much prefer
to be close together again.
And once you've let the
heat to get it started,
it continues and makes
an awful lot of activity
while it's going back together again.
And all this nice light
and everything comes out
and everything is being undone,
you're going back to carbon and oxygen,
back to carbon dioxide.
And the light and the
heat that's coming out.
That's the light of the sun that went in.
The sun that went in.
So it's sort of stored
sun that's coming out
when you burn a log.
So it's sort of stored
sun that's coming out
when you burn a log.
So it's sort of stored
sun that's coming out
When you burn a log
So it's sort of stored
sun that's coming out
When you burn a log
So it's sort of stored
sun that's coming out
When you burn a log
So it's sort of stored
sun that's coming out
When you burn a log
