The fundamental currency of our universe is energy.
It lights our homes, grows our food, powers our computers.
We can get it lots of ways:
Burning fossil fuels, splitting atoms,
or sunlight striking photovoltaics.
But there's a downside to everything
Fossil fuels are extremely toxic,
Nuclear waste is... well, nuclear waste,
And, there are not enough batteries to store sunlight for cloudy days yet.
And yet the sun seems to have virtually limitless free energy.
Is there a way we could build a sun on Earth?
Can we bottle a star?
[Intro Jingle]
The sun shines because of nuclear fusion.
In a nutshell, fusion is a thermonuclear process.
Meaning that the ingredients have to be incredibly hot.
So hot, that the atoms are stripped of their electrons
Making a plasma where nuclei and electrons bounce around freely.
Since nuclei are all positively charged,
They repel each other.
In order to overcome this repulsion,
The particles have to be going very, very fast
In this context, very fast means "very hot"
Millions of degrees
